Design and fabrication of agriculture multi sprayer / Nabil Najwan Salehudin Alayob and Syidatul Akma Sulaiman

In agricultural sector generally farmer uses traditional way that is spray carried on backpack and spraying crop. This becomes time consuming, costly and human fatigue is major concern, these problems can be overcome by using agricultural multi sprayer. The main objective of the agriculture multi sprayer is to reduce the workers energy and can make the work quickly and smoothly. It facilitates uniform spread of the chemicals, precision made nozzle tip for stream and capable of throwing foggy spray depending on requirement. In our project we use sprocket and chain that be connected by the connecting rod mechanism to convert rotary motion into reciprocating motion to operate the pump, thus the pesticide is spread through the nozzle. This work gives continuously flow of pesticide at required pressure and height. By using agricultural sprayer, spraying time human efforts reduces because the workers didn’t need to pump manually and results in cost reduction
