Design and Fabrication of Automatic Pesticides Sprayer

Abstract

Farming is the heart of Indian culture .Agriculture sector largest Employment providing sector. The farmers comes under different levels according to their economic condition like small marginal medium and rich farmers. In large scale rural area farmers using manually operated instrument instead of new techniques. In addition to that spraying pesticides is also preliminary action taken by farmers to protect crop from insect diseases fungi and pests. Number of technologies are used for spraying pesticide by using electric solar and chemical energies. Instead of wasting these energies we can use mechanical energy. Although using
these equipment's farmers face different problems like expensive than manual. less working area less sprayer tank capacity more time consuming etc. To overcome these limitations number of product are launched in market. But they are not able to come over all the limitations at a time. We found a solution for all the problems by developing model which is based on crank-mechanism and mechatronics system mainly Bluetooth RC controlled. Main objective of this paper is to construct automatic pesticide sprayer to minimize the farmer efforts. An accurate working model has been fabricated. It gives similar nozzle pressure and cover maximum area. We used crank-mechanism along with piston pump. which is derived by rotation of wheel. for the turning moments and liner motion of system with help of planetary gear motor, Motor driver, remote and controllers.
