Design and Development of Fertilizer Spraying Machine

Abstract

In agricultural sector, generally farmer uses the traditional way of carrying a spray tank on his back and spray onto the crop. This is time consuming, costly and fatigue is also a major concern. These problems can be overcome by using a reciprocating multi sprayer. It facilitates uniform spread pesticides or insecticides. Precision made nozzle tip is used for adjustable stream capable of throwing foggy spray depending on the requirement. we use a slider crank mechanism to convert rotary motion into reciprocating motion to operate the pump. The pesticide is spread through the nozzle giving a continuous flow of pesticide at the required pressure. A special arrangement adjusts the pressure from low to high. We also use a weed cuter for removing the unwanted weeds. By using this agricultural sprayer, spraying time, weeding time and human efforts are reduced and resulting in cost reduction. Aim of the project is that the farmer need not carry the entire pesticide sprayer pump on his shoulders, but just pull/push the mechanism mounted on the trolley to operate the pump to spray.This makes the farmer feel more comfortable, relaxed and less tiresome by reducing human efforts due to the constant pumping action.
