Development of A Manually Operated Sprinkler Machine

Authors: Nweke, Collins Sopuluchukwu

Abstract: This project focuses on the development of a manually operated sprinkler machine for pesticide spraying in agricultural fields. The aim is to improve productivity, reduce costs, manpower, and minimize environmental impact. The project report begins by discussing the background of farming and the importance of effective disease and pest control. Various types of sprinklers used in agriculture are examined, along with the use of fertilizers and pesticides. The limitations of current farming machinery are identified, including high costs, complex designs, transportation difficulties, and inefficiencies in pesticide application. The objectives of the study are to select the materials and to design and fabricate the sprinkler machine. The working principle of the machine involves converting rotary motion from the chain drive to reciprocating motion with the help of a connecting rod that is attached to the pump and the driven or rear sprocket thereby allowing the pump to pressurise the pesticide in the container and discharge it through the nozzles. The methodology discusses the systematic approach to design and fabrication, considering factors such as farm requirements, crop types, and safety standards. The results and observations demonstrate the machine's ability to provide a stable flow of pesticide, achieve an even spray pattern, maintain hose connectivity, and ensure smooth wheel and chain drive operation. The discharge rate and coverage area meet the necessary specifications, and the machine proves to be user-friendly and easy to operate.
