India is set to be an agricultural based country and approximately 75% of the peoples are dependent on farming directly or indirectly, in this agriculture sector there is a lot of field work, such as weeding, reaping, sowing etc. Apart from these operations, spraying is also an important operation to be performed by the farmer to protect the cultivated crops from insects, pests, fungi and diseases for which various insecticides, pesticides, fungicides and nutrients are sprayed on crops for protection. In today's world, we use many different spraying technologies involving use of energy like electrical energy, solar energy, and chemical energy of fuels. This fact makes us know that how large amount of energy is getting used at such place where mechanical energy can be used instead of direct energy sources. Farmers are facing enormous problem while spraying the pesticide like tank capacity is very small, high cost and spaying time taken more. In order to reduce these problems many different type of sprayers has been introduced in the market, but these devices do not meet the above problems or demands of the farmers. To solve these difficulties develop a new equipment that is mechanically operated wheel driven sprayer, it is a portable device and does not need any fuel to operate, which is easy to move and spray the pesticide by moving the wheel. This wheel operated pesticide spray equipment consumes less time and achieves uniform nozzle pressure; we used crank mechanism with piston pump, which is driven by the wheel The Project aims at developing a low cost mechanically operated sprayer pump for Indian middle scale farmers, Study the literature review, user study and market study. Based on literature and market study develop QFD and PDS char, and generate the many concepts. A final concept has been select for further development and detailing. A full scale working model has been fabricated for design validation. The device has been validated with the user group and got good feedback from the user.
