How does a hand sprayer work? How to make a homemade garden sprayer from improvised materials. canister sprayer

When carrying out horticultural work, a lot of effort goes into the fight against pests attacking vegetable and berry beds, bushes, fruit trees. The processing season with special products begins in early spring and ends in late autumn. It's time to think about how to make a sprayer with your own hands in order to fully meet uninvited guests. It is worth considering that an assistant in confrontation with insects should not become a source of additional problems. The dosage of drugs and the accuracy of spraying the liquid are important.

Types and arrangement of different types of sprayers

High-quality processing of plants by various means is a responsible task. It is necessary to observe a set of unwritten rules, the main of which is do no harm. An overdose of chemicals is fraught with detrimental consequences. Spraying is carried out using special equipment. Regardless of whether it is planned to purchase ready-made equipment or self-assemble a garden sprayer, they start with choosing the optimal model.

Simple hand sprayer

The simplest hand tool

It is intended for processing of small sites, beds and undersized bushes. It features a simple design solution: a pump-action pump is mounted in the tank lid, with the help of which air is pumped and the required pressure is reached. The solution is sprayed by pressing the lever. Working volume - from 0.5 to 2 liters.

Care must be taken during operation to avoid contact with airborne chemical particles. The device is kept away from the face, and work is carried out in a medical mask and protective gloves.

How a pump sprayer works

This model is convenient for processing low trees, shrubs, vegetable gardens. It is characterized by a more advanced device than the manual counterpart. The lid performs a dual function - it clogs the liquid inside the container and at the same time is a pump. Working volume - from 3 to 12 liters, pressure - 3-4 atmospheres. Equipped with a shoulder strap.

The drug is supplied through a hose, at the end of which a rod 1-3 m long is fixed. The liquid is sprayed through a nozzle, which makes it possible to cover a larger area than when working with a manual counterpart.

Pump sprayer has to be carried around the site

Sprayer knapsack manual type

The knapsack garden sprayer is designed for processing large areas - up to 0.5 ha. It has two chambers - pumping and working volume from 12 to 20 liters. For safety reasons, the pump is separated from the solution container. If the air chamber ruptures under overpressure, the liquid will not spill or cause harm.

A significant disadvantage is the need to constantly maintain pressure in manual mode. At the same time, it has a fairly high performance and extended operational capabilities. A careful study of the design will help you decide how to make a do-it-yourself tree sprayer if you don’t want to spend money on a production model.

Knapsack hand sprayer is mainly used for work in summer cottages.

Knapsack accumulator sprayer

This type of equipment is referred to as "enhanced comfort" models. Structurally, it almost does not differ from a manual knapsack sprayer, but it has an important advantage. Air is not pumped in manually, but with a battery-powered pump. The energy source is charged from a conventional household network. Offline work is about 3 hours.

There is a wide range of models on the market with a capacity from 12 to 20 liters. You can purchase a small sprayer with a volume of 5 liters. Another valuable feature is the telescopic rod, on which up to 3 nozzles can be mounted.

Mandatory attribute - nipple valve for pressure relief

Pump type home appliances

Pumping tools do not have a working capacity and resemble compact bicycle pumps with a hose, the free end of which is lowered into a vessel with a solution for treating plants. Such a unit is convenient for processing a garden, shrubs and low trees.

The solution can be poured into a container of any size and any configuration - a bucket, a canister, a barrel and even a bottle. To fill the vessel, you do not need to disconnect or disassemble anything. Ideal for the use of different solutions - you do not have to wash the dishes before filling with another composition.

Design features of the sprayer

Each country house, backyard or small farm has its own needs for processing plants. Therefore, the desire to assemble the equipment on your own or modify the factory sample is quite justified.

Most often, home craftsmen are driven by the desire to improve the labor-intensive process of processing trees. The height of some fruit crops reaches 10-12 m, and the tops of walnuts are completely inaccessible.

The task is simplified by the simple design of the sprayer:

• working container made of materials that are insensitive to the effects of chemical compounds;
• pump, electric or gasoline pump;
• pump chamber;
• sealed lid;
• safety valve to relieve excess pressure;
• flexible hose for supplying the finished solution;
• lever or trigger for adjusting the supply of the drug;
• a rigid rod of the required length, on which the sprayers are fixed.

Do-it-yourself sprayer assembly scheme

How to make a garden tool from a canister

The easiest way to self-assemble is to make a sprayer from a canister, preferably a metal one. The container is durable, resistant to corrosion, insensitive to chemical compounds.

The most convenient is a canister with a volume of 10-12 liters, to which it is easy to adapt belts and make a satchel. Any one is suitable as a pump: foot-operated automobile, electric vibration, for example, the popular "Kid", which is found in many households.

An ordinary nipple is suitable for mounting the valve, and accessories - a hose, a rod, nozzles - are sold at any agricultural store.

The canister is used as a container

However, there is a significant drawback. If the work is planned to be carried out on a large area, you will have to use an industrial extension cord or look for other options for connecting to the network. But on a plot of 6-8 acres, the unit is indispensable and will be a reliable assistant.

The advantages include the use of an electric pump, which significantly expands the range of application of the sprayer. In the spring, many summer residents use a soapy solution to wash the bark of trees. In autumn, in order to prevent diseases, they are treated with urea and other natural remedies.

The electric pump allows you to maintain a constant pressure of 2 bar, which has a positive effect on the spraying efficiency. But what if the site does not have 6 acres, but all 60?

Milk cans with a capacity of 30 liters are often used as a tank.

How to assemble a unit for processing large areas

Homesteads or farms, large in size, are treated with sprayers with a volume of 100 liters or more. A walk-behind tractor or a minitractor acts as a draft vehicle. An indisputable advantage of the design is the ability to connect the pump to a walk-behind tractor using a belt drive or a power take-off shaft.

Suitable for use when spraying:

• gardens;
• vineyards;
• fields.

Step by step assembly

Depending on the need, vertical or horizontal rods are used. It is also possible to adjust the pressure. For example, when lifting the solution to a considerable height, 2 bar may not be enough, and you will have to raise the pressure to 3-4 bar.

Before you make a sprayer on a walk-behind tractor, perform the following preparatory work:

1. Install the container. Not only the material of the tank is important, but also the volume. Consumption of the drug per 100 sq. m ranges from 2 to 5 liters, depending on the intensity of spraying and the number of nozzles.
2. Assemble the structure almost by analogy with a homemade knapsack sprayer. Be sure to provide a valve to relieve excess pressure.
3. Connect and turn on the pump. When choosing equipment, they check whether the model is suitable for the walk-behind tractor.
4. The rods equipped with nozzles are hung and brought into working condition.

Important requirements and assembly videos

When spraying orchards, telescopic booms are usually used. This makes it possible to process trees of various heights and not waste time, irrigate leaves and branches with a solution from all sides.

The length and number of nozzles on the horizontal bars used in the processing of fields depends on the width of the beds, as well as the dosage of the solution for every 100 square meters. m. The optimal distance is 40-50 cm. Under pressure, the drug is sprayed evenly from all holes, and the level of irrigation of each plant will be approximately the same.

The motor sprayer is productive and convenient, but its cost is also high

Do not confuse two different types of equipment - a motor-sprayer and a structure that is mounted on a motor-block. In the first case, we are talking about an improved autonomous professional model powered by a gasoline engine.

The rest of the sprayer is similar to knapsack counterparts. Its performance cannot be compared with devices designed for fields and gardens. You can clearly see the differences in the video.

How to use the sprayer pump

The pump is the key and most expensive component in a sprayer system, which often stifles the desire to automate the irrigation of a garden or vegetable garden with medicinal solutions. Is it worth buying special equipment, or will it be possible to get by with improvised means?

Homemade from a tank

New life for car battery

Car owners change the battery about once every five years. Responsible - more often, without waiting until the density of the electrolyte drops to a critical level. But maintaining a vehicle's electrical system is one thing, and generating power to power a low-powered motor is another.

The design is simple:

• metal grips are connected to the battery;
• connect a two-core electrical cable in a soft braid and a standard cigarette lighter (it is important to observe the polarity);
• a motor is placed inside the container, which acts as a pump;
• connect with hose and sprayer;
• get to work.

Such a device is suitable for processing strawberries and other undersized crops. A significant drawback is that the working area is limited by the length of the cable. The battery is charged using a standard device.

Centrifugal pump

Using a centrifugal pump

You can make a garden sprayer with your own hands using a conventional centrifugal pump that has served its time in a well or well. Additionally, you will need a pressure regulator, which is a tee with a shut-off valve for connecting a washing machine. The item is installed on the outlet shoulder.

Next, the assembly is carried out according to the general scheme, the solution is prepared and poured into the container. Lastly, the pump is immersed and set to work. The disadvantages of this option include the stationary position of the liquid tank, which is compensated by the length of the hose.

The power of the centrifugal pump is large enough to maintain the required pressure. Also, the design is effective for irrigation.

Scheme of the sprayer from the pump "Brook"

The option of using a 12V battery pump is not ruled out. The small unit has enough power to ensure uninterrupted operation for several hours.

The undoubted advantage is the ability to connect the device to a conventional manual pump-action sprayer, in which the pump has failed. This is not just a repair, but a modernization that will significantly speed up the work.

There is nothing better than making the world a better place on your own. But if it is not possible to make a sprayer with your own hands, you should take a closer look at the finished models and consult with professionals. Experts in garden equipment will tell you the best model suitable for use in a particular household. Your backyard everyday life will become less busy with labor-intensive work, and you will find time for new ideas and achievements.

From timely and quality use of special means when growing a crop, the quality of the grown products, its productivity, and, ultimately, the return on financial and physical investments depend.

Every gardener wants to please himself and his loved ones with a crop grown with his own hands, which can be saved and further increased.

A garden sprayer is an important and highly effective tool in the competent organization of labor in a garden plot, which allows you to protect the plant, fertilize it in time, carry out prevention, while using a minimum of harmful substances, acting selectively and accurately.

How does a garden sprayer work?

Any sprayer works on pressure difference principle ambient air and working fluid (chemicals or fertilizers) in a sealed container. Sprayers work on the same principle, and for.

Due to the high pressure, the liquid tends to break out and, when the valve is opened, passes through a flexible hose and a hollow telescopic “fishing rod” with nozzles, spraying in the form of a cloud, a fan, a jet, or in a combined form.

The pressure of the working fluid is created in various ways, depending on the device and the purpose of the sprayer. It can be a powerful motorized sprayer for trees 5-10 m tall or a simple hand sprayer for plants in a flower bed.

For more information about garden sprayers, see the video below:

Classification according to the method of creating pressure of the working fluid

Motor sprayers

The most powerful from garden sprayers - these are motor sprayers; spraying occurs under the pressure of a jet of air created by a membrane-type pump driven by a small engine, usually gasoline.

Membrane type

Diaphragm type pump (membrane, diaphragm pump) - a positive displacement pump, where the working body is flexible plate, fixed at the edges. Under the action of some mechanism or forces, the plate bends, performing the function of a piston pushing the working fluid.

Electric knapsack

A slightly less powerful class is the electric backpack garden sprayer. The diaphragm pump is powered by a 12 volt battery.

Due to its optimal power and size, this sprayer has gained wide recognition and is often used for more than its intended purpose; and for example, for window cleaning or as a sprayer in construction and renovation. You can also make . The working fluid is in a container behind the back of the operator.

Garden backpack

Garden backpack sprayer manual - the most simple, convenient and versatile option. The pressure in it is created by manually moving a special lever that controls the pump pump. Increased pressure is created in a special pumping chamber, from where the liquid is supplied to the spraying system.

pump action

The pump pump is cylinder with a moving piston; at the end of the body there is a valve for the intake of pumped air into the working area and for preventing its exit, thereby forcing an increased pressure of the working fluid.

Knapsack manual

There are also manual knapsack sprayers with pressure pumping pump directly into the container with working fluid. Their disadvantage is the not always strong design of the seams of the working container, as a result of which the seams can diverge, which can lead to operator burns.

Video on how to choose the right sprayer.

Be careful with these models.

Pump on the belt

An automobile electric pump was originally designed for pressures up to 3-4 atmospheres and often has a built-in pressure indicator.
Stages of work:

1. A hole is marked on the cylinder where the nipple will be installed. It is better to mark closer to the neck for the convenience of future connections.
2. The hole is drilled slightly smaller than the diameter of the neck of the nipple for its tight installation.
3. The rubber seal of the nipple is lubricated with liquid soap and the nipple is inserted into the drilled hole using round nose pliers. After installation, the nipple should hold pressure.

Assembly and connection of the pump:

• pour the required amount of liquid into the balloon;
• connect the pump hose to the nipple on the cylinder;
• connect the wires of the battery and the car pump, observing the polarity;
• turn on the pump and watch the pressure readings; when the pressure reaches 2.5-3 atm, turn off the pump;
• check the sprayer in operation.

After setting the required jet quality, the system is set up and ready for operation. Next, the pump with the battery must be fixed on the sprayer cylinder. For this, any rectangular bag of the required size is suitable. It is desirable to make a hole in it for reading the pressure gauge.

For additional fastening to the bag, you can sew straps - "Velcro" on top and bottom, the upper part of the straps will "grab" the neck of the cylinder, the lower - its middle part, making it possible to easily dismantle the entire structure.

12V 10Ah battery is enough for charging two bottles with a capacity of 5 liters, while charging the battery of the specified capacity can take up to 10 hours. If this is not enough to complete all the work, you can purchase a second battery and charge them alternately.

And finally, the easiest option. How to make a sprayer from a simple plastic bottle. If you have a desire to increase spraying performance without buying expensive devices, you can do with little effort.

For this you will need:

• a children's bicycle pump accidentally found on the mezzanine (or its store counterpart Puky HP-25);
• plastic bottle of the required volume;
• bicycle nipple;
• sprayer (spray nozzle screwed onto the throat of a standard plastic bottle);
• needle nose pliers.

Procedure:

1. We cut out the nipple from the old bicycle chamber along with the round rubber section into which it is glued. The diameter of the rubber “washer” is about the size of an average coin, it will serve as an internal seal.
2. We twist the sealing nut from the nipple body - it will tighten the connection from the outside.
3. We drill a hole in the upper part of the plastic bottle with a diameter for the nipple.
4. We launch the nipple into the neck of a plastic bottle and “catch” it inside with the help of two knitting needles, directing it into the drilled hole.
5. We grab it with needle nose pliers and pull the nipple out, pressing the rubber seal against the wall from the inside.
6. We drip a couple of drops of waterproof glue on the hole between the nipple and the edges of the drilled hole.
7. We cut out the second rubber sealing washer from the bicycle chamber and, after the glue has dried, carefully put it on the nipple.
8. We twist the nut on top of the nipple until it stops.

It remains to screw the hose from the pump to the nipple, fill in the liquid and screw the spray gun onto the neck.

If the size of the plastic bottle is noticeably larger than the liquid intake pipe that comes with the spray gun, any plastic tube of the same diameter will work for replacement; the main thing is that she got to the bottom and had a slightly "oblique" cut.

After installing the sprayer, it is necessary to fix the pump with transparent tape on the bottle.

The pump handle in the closed position should be slightly higher than the neck of the plastic bottle and spray gun, so that the fingers of the hand do not touch its walls and interfere with the pumping process, and also so that the handle does not interfere with unscrewing the spray gun.

Make several pumping movements with the pump, feeling how the walls of the bottle become elastic. Having pumped up the container almost to the density of a “soda bottle”, you can press the spray gun handle. The pressure of the jet and the absence of the need for frequent pumping will pleasantly please you.

Conclusion

Modern imported devices are not always economically viable in our unstable climate, when it is not always possible to harvest even one crop. Russian products do not always reach the required level in terms of quality and reliability.

But this only means that, having shown ingenuity and ingenuity, you can collect no less efficient and reliable do-it-yourself copies that are not inferior to the best samples, albeit not in design, but in reliability and overall efficiency.

Summer residents who are engaged in growing plants on their plots know how important it is to properly and timely care for plantings, whether it be trees, bushes or flowers. For effective care, every amateur gardener or gardener has a garden sprayer. Often gardeners-inventors make a sprayer with their own hands. It should be noted that it is not so difficult to design a homemade sprayer on your own, providing good care for all plants and protecting yourself from frequent machine repairs.

The main task of a garden sprayer is to effectively spray liquid (chemicals, fertilizers, stimulants, etc.) onto plants. The liquid applied in this way adheres perfectly to the plantings and exhibits its protective properties for a long time. Spraying is a necessary measure to protect bushes and fruit trees from diseases and pests (caterpillars, aphids, mites, etc.). In order for the processing process to proceed correctly, it is worth using special equipment - a garden sprayer.

All devices of this purpose can be divided into groups according to the principle of operation (from elementary manual to self-propelled). There are the following types:

1. Manual sprayer, which is a plastic tank with a lid with a built-in pump pump. The pump creates the necessary pressure in the tank, then you can spray the liquid by pressing the lever located on the handle. Units of this type are produced with a tank volume from 0.5 to 2 liters. It is excellent for spraying seedlings and other small plantations.
2. The pump sprayer is designed for spraying a large number of plants. The volume of the tank is 3-12 liters. It must be worn on the shoulder on a special belt. There is also a pump on the lid, and a hose (1-1.5 meters) with a special handle, a rod and a nozzle comes from the body. Today, pump-action garden sprayers are one of the most popular. This is a great option for processing areas up to 30 acres.
3. Hand-held knapsack sprayer - here the pressure is built up in the pump. Devices of this type are convenient in that they can be carried behind the back, like a backpack. When processing plantings with the help of this unit, you need to pressurize with one hand, and hold the spray bar with the other hand, which is not very convenient and rather tiring.

1. The backpack battery sprayer is an improved model of the previous one. Its main advantage lies in the fact that the pressure is generated by means of an electric drive from the battery. Such a mechanism greatly facilitates the process of processing plants and speeds up the process. Electric garden sprayers, due to their efficiency and productivity, are suitable for small private gardens and vegetable gardens, as well as for mini-farms.
2. It is expedient to use a petrol motor-sprayer for work on large areas. The volume of the liquid container here varies in the range of 12-20 liters. Sprayers of this type are divided into two types: knapsack, which are worn behind the back; wheeled, which can be freely moved around the garden and vegetable garden.

All of the above units can be easily bought in the markets or specialized stores, as well as ordered via the Internet. But you can do it on your own by making the device yourself from available materials. Perhaps this method will be the most correct, because a self-made garden sprayer can be easily adjusted to your needs and not worry about repairs in case of any breakdown.

What materials will be required

Many gardeners and gardeners use home-made means for spraying green spaces on their plots. You don't have to be an engineer or an inventor to make a garden sprayer - just be smart. For work in the garden or greenhouse, you can use an ordinary broom that will cope with the role of a sprayer. This is a cheap and easy method, but not very practical as chemicals are spilled in the process.

To process a small number of bushes or seedlings, you can make an excellent manual sprayer from a windshield wiper container. Before use, you just need to wash the container well to clean it of unwanted elements. If you plan to create a more advanced garden sprayer, for example, an electric one, then you will need quite complex and serious parts: a tank, a pump, a check valve, a reinforced hose, a spray bar, a push-button switch, a stranded wire, etc. If you wish, you can even do self-propelled vehicle, but for this you already need to use equipment.

How to do it yourself

Consider how you can design a battery sprayer. To make it, you need to take a tank - an old pump-action sprayer with a broken pump that cannot be repaired is perfect. At the same time, it is extremely important that there is an airtight tank, a working rod and an air valve.

You will also need a battery (12 V) and a car compressor. You need to drill a hole in the tank and insert the car nipple to which the compressor is connected. To seal the hole for the washers, you can lay a rubber gasket or blow it with sealant. Then the compressor must be connected to the battery.

Due to the high pressure in the tank, the spray is very fine. The required pressure is pumped up, and its excess exits through the valve. The undeniable advantage of a self-designed battery sprayer is the ability to repair and replace any element. When working with any sprayer, it is worth remembering to follow the safety rules: protective clothing, use gloves, a respirator, a headgear. At the end of the work, the device should be disassembled and thoroughly rinsed with water, then dried and reassembled.

The future harvest fully depends on how timely and efficiently special tools are used for processing horticultural crops and trees. In this regard, every gardener on the farm should have a manual pump-action sprayer.

This is a practical tool that helps to perform high-quality crop processing or top dressing, acting efficiently and accurately.

Tool Feature

Until recently, a simple broom soaked in special chemicals was used to treat plants and trees in the garden. It is hard to call this method practical, effective and convenient.

In addition, the use of a broom often led to the poisoning of the gardeners themselves.

Today, almost every gardener has a special tool with which the process of processing horticultural crops becomes much easier, more convenient and more efficient. This is a sprayer.

Modern manufacturers offer a wide range of sprayers, each of which has design features, advantages and disadvantages.

The most popular among different types is a manual pump-action sprayer.

Regardless of the type of sprayer, its design remains standard. It consists of the following elements:

The quality of each of the above elements affects the efficiency of the sprayer, as well as its life.

The principle of operation of the equipment

The popularity of manual garden pump sprayers among gardeners and gardeners is primarily due to the simplicity of the design and the principle of their operation.

Summer residents, gardeners, farmers, villagers - all of them are united by work on the ground and care that this season grapes are not affected by mildew, tomatoes by late blight, potatoes are not eaten by the Colorado potato beetle, and fruit and berries are not eaten by aphids. And even decorative flower beds are not protected from pest attacks. That is why any self-respecting gardener should have a garden sprayer in his arsenal. With it, you can not only spray pesticides or biological products that harm pest populations, but also home-made protective solutions, all kinds of foliar top dressing, fertilizers and biostimulants. Choosing a good reliable sprayer is not such an easy task, as a seemingly high-quality product can actually have a lot of flaws that will “come out” at the first use. And the variety of forms of sprayers, their principles of operation, functionality only complicates the task. In this article, we will talk about how to choose the right garden sprayer and how to make it yourself.

What are garden sprayers?

It is most convenient to subdivide garden sprayers according to the principle of operation, especially since their volume, convenience and functionality are also very dependent on this. Modern manufacturers of garden sprayers produce various products from almost all categories, which will be listed below. Each has its own line, which has individual characteristics.

Manual garden sprayer

A manual garden sprayer is a plastic container with a lid, in which a pump pump is mounted. Using the pump, the necessary pressure is created in the container by pumping by hand, then the solution can be sprayed by pressing the button or lever located on the handle. Hand sprayers come in 0,5 l before 2 l. This volume is enough to process seedlings, plants in a greenhouse or flower garden. At the same time, the sprayer body itself is held in the hands or even in one hand. The price of a garden sprayer largely depends on the manufacturer.

gardena produces manual sprayers with such a volume of 0.5 l, 1 l, 1.5 l. All models are equipped with a safety valve for air release, a filter and a liquid control scale, a nozzle nozzle perfectly regulates the flow of water - you can make both a jet and a fine spray. The products of the German company Gardena are one of the most expensive. For example, a 1.5 liter manual sprayer costs $30. For comparison, a sprayer of the same production volume Sadko will cost only $ 5, while it will also be equipped with a brass nozzle, much more durable than plastic.

Pump-action garden sprayer

The pump-action garden sprayer is a container from 3 before 12 l, which can be worn on the shoulder with a special belt. The cover of such a sprayer is also at the same time a pump, with the help of which a pressure of 3-4 atm is created in the tank. A 1-1.5 m long hose goes from the sprayer body, to which a handle and a 1-3 m rod with a nozzle at the end are attached. On the handle there is a button or lever, after pressing which the liquid begins to spray. For long-term processing, there is a shutter button that locks the open position of the nozzle. This greatly facilitates the work, since there is no need to constantly press the button. When the pressure in the container drops, it must be increased again using the pump, and then continue spraying. At the moment, pump-type garden sprayers are the most popular, as they can process land up to 30 acres.

Garden sprayer Marolex considered the most reliable and successful solution. Sprayers made in Poland have a metal telescopic boom of 80 cm (extends up to 1.35 m), an additional 3 m boom can be purchased for processing tall trees. All parts are made of high-strength materials that are resistant to chemicals and mechanical stress. The connections of all components and parts are thought out very well, the products serve for many years without breakdowns. A distinctive feature of the Marolex garden sprayer is the increased pressure in the chamber - 4 atm., Against 3 atm. from competitors. This allows you to use the device longer. At the moment, there are sprayers with a volume of 5 liters, 7 liters, 9 liters, 12 liters. They do not differ much in price, therefore, units of 12 liters worth 30 - 35 USD are considered the most popular, they can always be filled with less than the maximum volume. The only conditional disadvantage of Marolex can be called the fact that the mesh filter is not too fine-meshed.

Comparison garden sprayer Solo made in Germany is somewhat more expensive, 11 liter model - 55 USD. But at the same time, the sprayer handle is non-telescopic, only 50 cm long. The pressure in the tank is 3 atmospheres. The kit includes many different nozzles, a wide jellied funnel. A significant advantage of Solo sprayers is the manufacturer's warranty for 5 years, but in the absence of service in the region, it is simply meaningless.

Sprayer garden knapsack manual

A knapsack sprayer is somewhat different from a pump-action sprayer. The pressure is injected not in the chamber with the solution, but in the pump chamber, this serves as a kind of protection for the operator, since even if the chamber bursts from excessive pressure, the solution will not spill. Knapsack sprayers have straps that can be used to carry them on the back, and an additional fixation strap on the stomach prevents the backpack from tilting and moving. Such a sprayer is called manual because it has a handle on the side, with which pressure is pumped into the chamber. As a result, working with a knapsack unit looks like this: the apparatus itself is behind the back, with one hand the pressure is constantly pumped up (the handle jerks up / down), and the rod with the sprayer is held with the other. The system is somewhat tedious, although it allows you not to stop for pumping, as is the case with a pump-action sprayer.

Knapsack garden sprayers are 12 l, 15 l, 18 l and 20 l. They are used to process large plantings up to 50 acres. Some models allow you to rearrange the handle for right-handed and left-handed people. The weak point of such sprayers is the place where the handle is attached to the body. Please note that there is an additional cushioning material / plastic part between the handle and the body, otherwise the body will crack on the first day.

Oddly enough, the cheapest representative of this category is not a Chinese garden sprayer Grinda, for which there are many complaints, and the Polish analogue of Sadko. For comparison Grinda Fine Spray for 15 liters has a rather well-thought-out design and a mechanism for attaching the inflation handle, but on the other hand, the handle, for which it would be convenient to carry the device from place to place, is quite small and inconvenient. Otherwise - a metal telescopic rod, a nozzle with an adjustable jet, a wide mouth and a price of 50 USD.

In the same time Sadko SPR-12 for 12 liters comes with a repair kit, 4 spray nozzles and a brass nozzle, as well as a convenient handle for carrying the sprayer and costs only 27 - 30 USD.

The most expensive can be safely considered a garden sprayer Gardena Comfort Backpack Sprayer for 12 liters, which is no different from Sadko, but costs almost 100 USD. The body of the sprayer is made of high-strength plastic in a dark turquoise color, which makes it very difficult to see how much liquid is left in the tank. On the other hand, German quality gives hope that the unit will last a very long time.

Battery garden sprayer

If you pay 100 - 120 USD for a garden sprayer, then only for a battery. This is another type of knapsack sprayer, only the pressure in it is not built up manually, but with the help of an electric drive from the battery. This greatly facilitates the work, the second hand remains free, just know to direct the bar where necessary. The battery is charged from a conventional 220 V power supply, it lasts for 3 hours of operation. Usually such sprayers are produced with a tank volume 15 l, 16 l, 17 l, 20 l, but there are also small 5 l.

garden sprayer Sadko SPR-20E- one of the best and demanded units of this category. From 1 to 3 brass spray nozzles can be mounted on the telescopic rod, which greatly speeds up the processing. The kit comes with another plastic rod and a set of nozzles. The sprayer lid has a convenient handle, with which you can unscrew the lid and move the unit itself, but the second is questionable, since the weight of a full tank is very large, and the plastic fastenings of the handle are not so reliable. It is convenient to carry the sprayer behind the back on soft straps; a manometer and a pump power regulator are built into the body. Works absolutely silently in comparison with petrol units.

For large areas, it is more convenient to use a garden sprayer that runs on liquid fuel, such as gasoline. The volume of the tank for the sprayed liquid in such models is from 12 to 20 l. Gasoline sprayers come in knapsacks that can be carried on the back, and on wheels, they can be rolled around the garden or vegetable garden like a cart. Farmers with a large farm will be helped by a sprayer with long battery life, as you can freely move around the territory and stop only to top up the solution and fuel. Manufacturers claim that with the help of a standard motorized sprayer, up to 5 hectares of the garden can be processed in one working day.

The boom and nozzle in gasoline garden sprayers are very different from pump-action models, it is more like a fire engine hose. With the help of a powerful air stream, the water jet turns into a finely dispersed substance, which can be sprayed with a wide or narrowly directed jet. The jet range reaches 15 m (8 - 15).

The cheapest unit from this category is a Polish garden sprayer Sadko GMD-4212. The 2 horsepower gasoline engine runs on A92 gasoline, sprays up to 8 m, nozzles are included, and a rotary nozzle allows you to spray liquid in the form of a "fog" or aerosol. The capacity of the solution tank is 14 liters, the cost of the sprayer is only 200 USD. This manufacturer also has more expensive models, for example, Sadko GMD-7717. It is equipped with a more powerful motor (5 hp) that sprays liquid 15 m horizontally and 12 m high. Its cost is about 325 USD.

A more expensive option garden sprayer Stihl SR 450 Brazilian production with a 14 l tank and a 3.5 hp engine. This model has a perfect engine start system, which reduces shocks as much as possible, and an anti-vibration system, which unloads the back muscles of the worker. The cost of such a sprayer is about 700 USD. Around the same price range are petrol garden sprayers. SOLO(Germany) for 12 and 20 liters with engines of 2.9 and 4.1 hp. costing from 700 to 900 USD

For ease of use, it is better to choose models in which the engine start button and speed control are on the handle. This greatly facilitates the work and allows you to quickly respond to different situations.

Mounted sprayers are used only in tandem with a tractor or other heavy equipment, so they are well suited for processing vast farmlands. The unit is hung on tractors such as T-25, T-40, YuMZ, MTZ. The sprayer itself has a tank capacity 200 , 400 , 600 , 800 , 1000 or 2000 l, as well as a piston-diaphragm pump and a fan. With the help of a fan, such flow turbulences are created that the liquid is sprayed evenly, even falling on the back of the plant leaf. The cost of mounted sprayers starts from 1600 USD.

DIY garden sprayer

Garden sprayers cannot be attributed to durable units. Of course, there are times when a conventional pump-action sprayer lasts 10-15 years without any complaints. But more often the opposite happens - the pump fails, the lid bursts, the handle breaks. All these breakdowns are very unpleasant, because if the nozzle and filter can be changed, then repairing the pump will either be too expensive or simply impossible due to the lack of parts. That is why many do not dare to buy expensive sprayers, but prefer to make them on their own.

Although the battery sprayer does not belong to super-expensive models, you can still save money on buying it by making it yourself from improvised materials. The tank is old or new. pump sprayer, for example, a garden sprayer Kvazar with a non-working pump. The main thing is that the tank is airtight, the handle and the rod are working, and there is air valve to relieve excess pressure. Next, you need a car compressor and a 12V battery.

We drill a hole in the sprayer tank and insert it into it car nipple to which we connect compressor. To seal the hole, sealant can be blown under the washers or a rubber gasket can be placed. We connect the compressor to a 12 V battery or to two 6 V batteries. All additional devices (compressor and battery) can be attached to the sprayer body with adhesive tape or electrical tape.

Due to the constantly high pressure in the tank, the liquid spray is finely dispersed and of high quality. You do not need to pump anything manually, and excess pressure is released through the valve. The advantage of a home-made battery sprayer is the versatility of additional equipment; in case of failure, you can buy a new one in any store and any model, and not look for a new battery for a specific sprayer model.

Electric Homemade Garden Sprayer

The manufacturing technology of a homemade sprayer described below is suitable for processing gardens and vegetable gardens at a small distance from the power source. You can move the sprayer around the territory on a hand cart or wheelbarrow, unwinding a large coil with an extension cord.

We'll need capacity, a large plastic barrel or even a milk can will do, as well as vibration pump, pump sprayer sprayer, flexible hose, adapters and push button switch.

We put and fix the container on the hand cart, lower the submersible vibration pump into it. If the water intake hole at the pump is at the bottom, then we lower the pump almost to the very bottom. And if from above, then we attach a hose to it and lower the hose to the bottom. The pump outlet hose and cable are led out through the cover. Please note that an air intake hole must be provided in the lid so that a vacuum is not created inside the container after pumping out the liquid.

We connect the supply hose of the pump to the hose leading to the rod, we crimp the connection. We disconnect the electric cable supplying the pump into two outside the tank, we lead one core to the switch.

The sprayer boom must have a button or trigger to turn on the liquid supply. Under this button or trigger, you must install a push-button switch that will turn on the pump. It turns out that when we press the button, the pump turns on and the liquid begins to flow, we release the button and the pump turns off. In more detail, all the details can be seen in the photo.

How to choose a garden sprayer

A garden sprayer is selected for a certain type and scope of work, so the main selection criteria will be the volume of the tank, the principle of operation, functionality and workmanship.

Sprayer volume. The capacity of the liquid tank is necessary to process the maximum area at a time. For a garden or vegetable garden with an area of ​​​​up to 15 acres, 9 - 12 liters is enough. Sprayers with a smaller volume are suitable for processing flower beds, small flower beds or several trees in the garden. For example, to process one small tree, 2 liters of solution are needed, and one large tree 8 - 10 liters. Sprayers with a tank volume of 12 - 20 liters can be used in small farms or gardens. It is also important who will be spraying, if a fragile woman, then buying a sprayer with a volume of more than 8 liters is impractical.

Most often, the line of each manufacturer includes models of various sizes: 0.5 l, 1 l, 2 l, 3 l, 5 l, 8 l, 9 l, 12 l. For example, a garden sprayer Kwazar Polish-Ukrainian production can be selected for every taste and need.

Pump. All pump sprayers have the same principle of operation of the pump. Air is pumped by moving the handle up and down. A pump in a metal case is more reliable and durable, although much depends on the quality of the material. For some, plastic pumps last 20 years, while for others they burst after a week.

Nozzle - sprayer. The nozzle is also an extremely important element of the sprayer. All modern models are equipped with a spray that can be adjusted to achieve a different type of jet. Many manufacturers offer additional nozzles in the kit. Most garden sprayers have nozzles made of plastic. And although a lot depends on the quality of the plastic, it is still better to pay attention to models with a metal brass nozzle, such as the Gardena garden sprayer. Its cost is an order of magnitude higher than that of competitors, precisely because the unit is equipped with a brass nozzle.

The bar is a hose. Standard fixed plastic rods are not the best option. Firstly, they are too short 50 - 80 cm. Secondly, they are not very reliable. A more durable and successful solution is metal telescopic rods. The optimal length of the rod is 1 - 1.5 m. An additional 3 m rod can be purchased for processing tall trees.

Important! Please note that not all manufacturers offer long handles and rods, and products from other models do not fit at the joints.

Air valve. The sprayer must have a safety valve through which excess pressure can be released. Some models are equipped with special marks that become visible if critical pressure is reached.

Replaceable nozzles and nozzles are offered by almost all manufacturers.

Liquid volume control scale helps to control the flow of liquid, as well as pour the exact amount of solution. Pay attention that liquid is visible through the body of the sprayer. For example, dark turquoise Gardena units do not allow you to see the liquid level, it is simply not visible, although the scale is applied. It is better to choose models from transparent or translucent plastic.

Belts and fasteners. The weakest points of sprayers are the fastening connections and the attachment points of the belts. It is almost impossible to repair them. Therefore, pay attention to the quality of performance. For example, the attachment points of the belts must be strong enough not to burst, and the attachment ring should preferably be made of metal. The attachment points of parts must be threaded from durable plastic or metal (very rare).

maintainability. The most important selection factor is the availability of the service of this manufacturer in the region and the availability of spare parts. The sprayer can be praised by everyone and everything, but yours will fail in a couple of months, and it will not be possible to repair it - it's a shame. Pay attention to the range of spare parts for a specific model of the sprayer, so that in the event of a breakdown it can be easily replaced. Parts that cannot be replaced must be strong, reliable and well thought out.

A garden sprayer is an important tool, but making it from start to finish, like some people make from an old fire extinguisher, is not practical. The cheapest pump-action sprayer (7 - 9 liters) costs 15 - 18 USD. For ease of use, it can be improved by hanging a battery and a compressor.
