Design, Assembling and Testing of Electric Knapsack for Greenhouse

Abstract

An experiment was conducted at Um Dom south east of Khartoum- Sudan. The objective of the experiment is to modify the motorised knapsack to be operated by blower, and to achieve the field performance test. Another modification was done to the way of compressing the liquid to the nozzle from the tank by replacing separate fan for this purpose and testing machine was the use of spraying plants cultivated in the greenhouses. The new design was done by replaced the internal combustion engine with electric motor and fan. The result shows that the flow rate per time achieved by the Assembling equipment is the same as the equipment before modification which is (3.79ml/sec). Also the cost of the new equipment is (110SDG) which is too cheaper than the motorized knapsack sprayer before modification (2500SDG).
