Why is a mechanical sprayer necessary?

 

The term "mechanical sprayer" describes a technique for treating crops with chemicals while utilising mechanical tools like sprayers and atomizers. Mechanical sprayers are designed to apply a variety of chemicals, including pesticides, herbicides, fungicides, and fertilisers. They are available in a variety of sizes and types.

Mechanical pumps are used to generate pressure in a tank containing the chemical solution in mechanical sprayers. The pump generates a fine mist that can be sprayed over crops by forcing the solution through one or more nozzles. This mist settles on the leaves and stems of the plants, where it can efficiently ward off pests and illnesses or supply essential nutrients.

How does agricultural mechanical spraying work?

A pump is used in mechanical sprayers in agriculture to create pressure that pushes liquid through a number of nozzles or atomizers. Depending on its chemical composition, the liquid may be a pesticide, herbicide, fertiliser, or other substance intended to defend or promote plant growth. The liquid is produced by the nozzles or atomizers into a fine mist, which is then sprayed onto the plants or soil. Depending on the needs of the crop and the kind of chemical being used, the spray mist can be altered to produce different droplet sizes.

The operator can control the rate and direction of the spray using a set of valves on the mechanical sprayer, which can be mounted on a tractor or other vehicle. The spray pattern and volume can be adjusted automatically by some sprayers based on the size and shape of the field, thanks to GPS and computerised systems.

Modern agriculture makes extensive use of mechanical sprayers, which can be very efficient at applying precisely measured amounts of chemicals to crops. To prevent misuse or environmental contamination, they must be used properly and cautiously.

How does mechanical spraying benefit farmers?

1. Time Saving: Farmers can save time by using mechanical spraying, which is quicker and more effective than manual spraying. This makes it possible for farmers to cover more ground in a shorter amount of time, which is crucial during the crucial phases of crop growth.

2. Consistent application: Chemicals can be applied uniformly and continuously over a large area by mechanical sprayers, ensuring that every plant receives the same amount of treatment. This makes it easier to control weeds and pests and guarantees that crops get the right amount of nutrients.

3. Precision: Mechanical spraying can be performed precisely and accurately, minimising the waste of chemicals and the possibility of over- or under-spraying. As a result, the overall cost of crop protection decreases.

4. Safety: Using mechanical spraying reduces exposure to potentially harmful chemicals, making it safer for farmers and their employees. This is so that the risk of exposure is decreased. Mechanical sprayers are made to contain the chemicals and reduce drift.

Components of a mechanical sprayer

Tank: The chemical mixture is stored in a tank that is a feature of mechanical sprayers. Small tanks on handheld sprayers and large tanks on sprayers mounted on tractors are two different sizes of tanks that can be used.

1. Pump: To pressurise the chemical mixture in the tank and force it through the spray nozzles, a pump is used.

2. Spray nozzles: Spray nozzles are used to apply chemical mixtures to crops. They are attached to sprayers. Depending on the crop and the application, different types of nozzles are used.

3. Boom: A boom is a protruding, extended arm made of metal or plastic that houses the spray nozzles on a sprayer. Depending on the application and the type of crop, booms can be either fixed or adjustable.

4. Pressure gauge: To make sure the chemical mixture is applied at the proper pressure and to monitor the pressure in the tank, a pressure gauge is used.

5. Control valves: Control valves are used to modify the pressure in the tank and the flow rate of the chemical mixture.

6. Filters: Before the chemical mixture is sprayed on the crops, filters are used to remove debris and other contaminants.

Range of sprayers

Sprayers can be divided into several categories based on the volume of liquid they handle:

1. High-volume sprayer (400 litres or more per hectare)

2. Sprayer with a low volume (5 to 400 litres per hectare)

3. Spraying with an ultra-low volume (ULV) device (less than 5 litres per hectare).

Nozzle’s Components

Nozzle body: It is the primary component that houses all other nozzle components.

Swirl plate: A metal disc with two tangential holes that causes the liquid it is in to swirl or rotate.

Nozzle Disc: The element that divides the fluid into tiny droplets is the nozzle disc. It resembles a flat disc with a hole in the middle. The spray solution is under additional pressure when it enters the disc from the swirl plate; as a result, when it leaves the orifice, it separates into tiny droplets. The disc is specifically designed to give the existing air a flat fan, hollow cone, or solid cone discharge.

Strainer: A strainer is a tiny, circular plastic ring with nylon wire mesh inside of it that is used to remove any dust particles from chemical solutions.

Spacer: To ensure that the solution travels effectively, two numbers of runner/plastic rings have been placed between the nozzle plate and the swirl plate and between the swirl plate and the strainer.

Conclusion

Modern agriculture requires the use of mechanical sprayers. Compared to manual spraying, they offer a more effective and efficient way of applying fertilisers, pesticides, and herbicides to crops. Mechanical sprayers are used to lessen the environmental impact of chemical applications, increase crop yields, and lower labour costs.

The ability to accurately and consistently apply chemicals, which results in better pest and disease control, healthier crops, and higher yields, is one of the main benefits of mechanical sprayers. Modern mechanical sprayers also come with cutting-edge features like GPS guidance, automatic boom height control, and safety features, all of which increase their effectiveness, accuracy, and safety.
