Design, Development and Fabrication of Agricultural Spraying Machine - Mechanical Engineering Project


Abstract:
Agricultural spraying is traditionally done by farmers who carries knapsack type sprayer because of its versatility, design and cost. But it is time consuming and requires human efforts causing problems like back pain.
Hence, in order to overcome these problems, we have designed and developed a new agricultural sprayer which is more efficient than traditional sprayers and requires negligible human efforts. A multi functional device will come in handy that can be used in different stages of farming as per farmers requirements.

Agricultural Spraying Machine
Introduction -
A sprayer is a device used to spray chemicals or liquids depending upon application. In agriculture, sprayers are used to apply herbicides, fertilizers and pesticides on crops. Sprayers come in different range of sizes from man portable units to self-propelled units similar to tractors.

Objectives -
To reduce overall cycle time for agricultural sprayer.
To reduce human efforts in order to reduce fatigue load on farmers.
Easy to assemble and disassemble.
Easy to operate by unskilled workers.
Highly durable.
Must be affordable.
Use of multi nozzles in order to spray large area at faster rate.

Types of Sprayers -
Knapsack Sprayer
Hand Sprayer
Pump Sprayer
Compression Sprayer
Garden Sprayer
Stirrup Sprayer

Disadvantage of these type of sprayers is that they are heavy, hand operated and has to carry on shoulders which causes fatigue to the operator. Hence, it became a need to design a sprayer which will overcome all above problems.

Construction -
This sprayer contains chain, sprocket, wheel, chassis (frame) with handle, connecting rod and a pump.

Working -
The connecting rod is engaged with the piston of the sprayer which reciprocates causing pumping action  resulting in increased pressure inside the pump which is further used to spray chemicals when the nozzle is opened on the sprayer line.

Advantages -
1. Human effort in pumping is reduced.
2. Increased capacity of spraying.
3. Fatigue load reduced.
4. Cost effective.
5. Increased rate of spraying thus reducing time in spraying.

Applications -
1. Agriculture.
2. Horticulture.
3. Florticulture.
4. Spraying of germicide.
