Familiarity with different types of sprayers and its efficiency

What does sprayer or pesticide literally mean?

The word Sprayer, which literally means sprayer or liquid sprayer, is a sprayer.
Sprayers or in fact foliar sprays are used to spray a variety of solutions such as pesticides, liquid fertilizers and micronutrients, amino acids and water to wash trees and plants and… on crops and orchards and various types of sprayers and Manual, motor, tractor and self-propelled sprayers can be used for spraying on target plants.
The components of the sprayers work together to suck liquid from the tank, compress the liquid, and finally spray the liquid with high pressure toward the target.
Manual sprayers, pump sprayers, rear motor sprayers, wheeled motor sprayers, motorized sprayer sprayers, tractor tractor sprayers, tractor traction sprayers and self-propelled sprayers are different types of sprayers.

Hand sprayers, motor and pump back sprayers

Hand sprayers are more commonly used in homes or small gardens. This sprayer is available in capacities of 0.5 to 5 liters and spraying is done by squeezing the air inside the tank using a pump and then by opening the valve or squeezing the toggle.
The housing of these sprayers is made of plastic and usually do not have high spray pressure.

Backpack sprayers are commonly used in small farms or greenhouses.
The capacity of this type of sprayer is between 10-20 liters and it is available in the market for its rechargeable and pump type or dual-use model that uses both of the mentioned types.
The air inside the tank of this type of sprayer, which is made of plastic or steel, is compressed using a pump or electric pump and produces a pressure equal to 2-8 times, and is sprayed by opening the spray valve or pressing the lance lever.
Pump motor and motor atomizer models are the two types of rear motor sprayers.
The performance of ball sprayers differs from that of motor rear sprayers.
Using a two-stroke or four-stroke gasoline engine, the pump connected to it rotates and the suction and compression of the liquid from the tank begins. The compressed fluid is directed to the lance with a pressure equal to 10-15 times and then sprayed on the desired tree or plant.
In this method, spraying and spraying the solution is wasted.
The tanks of these sprayers are available in capacities of 12, 14, 20 and 25 liters and made of polyethylene.
The functional difference between atomizer back sprayers, which are in fact the most standard type of garden and field sprayers in this type, is with powder-sprayed sprayers and diffuse liquid with compressed air or air, while liquid-sprayed pump sprayers They have hydraulics.
The nozzles of this device usually have a 4-way adjusting valve with the ability to change the amount of poison output, and the function of this device is to guide the liquid by gravity or by using a centrifugal pump in garden models.
The device is also equipped with a two-stroke turbine engine whose impeller is responsible for compressing and directing air to the hose and wind pipe. The high-pressure wind automates the liquid outside the nozzle and directs it to the target. This mechanism saves 50% in the use of pesticides and pesticides.
On the other hand, the mixture of air and liquid makes the pest control action more effective. It is also possible to equip this device with a micron nozzle equipped with a grooved rotating disk that breaks the liquid and automates it before the wind. This action reduces the consumption of toxins and increases the efficiency of the device.

Wheeled motor sprayers

Wheeled motor sprayers have a four-stroke gasoline engine with a power of 5 to 5.5 hp.
The tank is placed on a tubular chassis or iron profile, it is made of polyethylene or steel and is available in capacities of 100-200 liters. This sprayer, as its name implies, is portable and two rims and tires in the size of 350 x 8 are connected to its chassis with Excel.
This device has the same function as pump motor back sprayers and has the ability to use piston and diaphragm pumps.
The power required for the pump is supplied by a powerful gasoline engine or single-phase or three-phase electric motor.
The suction of the liquid inside the tank is done by the pump, the pistons equipped with the liquid packing are compressed and finally the high pressure liquid is sprayed from the sprayer hose and the lance towards the target.

Portable motor sprayers work similarly to wheeled motor sprayers, except that they do not have a tank.

This device is easy to move and is suitable for areas with limited transportation or difficult areas.
The appropriate tank of this device can be stored permanently in the garden, greenhouse or farm or it can be moved separately.

Tractor sprayers are a huge breakthrough in pesticides and agriculture

The required power of the sprayers behind the tractor is supplied from the PTO of the tractor and the required power of the device pump and canvas jacks in some models is supplied by the tractor hydraulic circuit.
This sprayer is available in two types of rider and traction. The rider type is connected to three points or the hydraulic arms of the tractor and is equipped with ceramic or diaphragm piston pumps that get their required force from the tractor, as mentioned before.
Some models have a centrifugal pump or centrifuge.
This type of sprayer is usually equipped with polyethylene nozzles with a capacity of 200, 400, 600, 800, 1000 and 1200 liters, and in other advanced and standard models, two other tanks are installed for hand washing and system washing.

Due to the lower speed and crushing of the crop, riding sprayers are more welcomed by farmers and especially farmers. The small volume of tanks is the only disadvantage of this type of sprayer, which has a higher volume of tanks with higher power tractors in new models.
Sprayers on the back of a riding tractor can be used in gardens, farms, greenhouses and even in livestock, especially livestock.

Sprayers behind the field tractor are available in two models with boom and turbine.
In the canvas model, depending on the volume of the tank, the ability to install canvases with a working width of 8 meters to 30 meters is available on the device.
This type of sprayer is the optimal and most suitable type of sprayers and agricultural sprayers in the world.
Field turbine sprayers are other types of tractor-mounted sprayers and their main use is in large fields of wheat, barley, canola and summer crops.
Due to the low accuracy of spraying, this type of sprayer should not be used to destroy weeds and is suitable for combating flying pests and insects.
Crop turbulent sprayer can be considered as a type of crop atomizer sprayer.
This type of sprayer uses a powerful centrifugal fan that receives the required power from the PTO tractor through a two-speed auxiliary gearbox.
In atomizer sprayers, the transfer of liquid to the nozzles is usually done with a low pressure centrifugal pump or by gravity, but in turbulents, this operation is done by a high pressure pump.
The vertical throw height of turbulent sprayers is up to 20 meters and their horizontal throw range is between 30 and 50.

Tractor sprayers have a mechanism similar to riding sprayers.
As their name suggests, these sprayers are pulled behind the tractor and have an axis and two wheels in proportion to the capacity of the tank, and therefore have tanks with a larger capacity and we have between 1000 and 3000 liters.
The tanks are made of polyethylene, steel or galvanized.

Low speed, lack of controllability and crushing of the product are the weaknesses of traction sprayers.
Tensile sprayers are suitable for farms equipped with a turbo liner or canvas, and are usually garden trowel sprayers equipped with a garden fan, which is also called a garden atomizer.

Features of self-propelled sprayers

Self-propelled sprayers, which are available in both garden and field, are usually equipped with a powerful and independent diesel engine that is used to provide the driving force of the hydraulic system, propulsion system and sprayer pump.
Although the garden type produces self-propelled sprayers, its canvas crop series, which is used more with canvases with their working width, is more in demand.
