Design and fabrication of an engine paddy rice suction transporter.

Abstract

A motorized paddy suction transporter machine made of locally available materials using local technology was designed, fabricated and tested for bagging and transporting paddy dried on the concreate pavements to solve intensive manual paddy rice drying activities done. The paddy suction transporter comprises of the following major components flat blades type centrifugal fan, power transmission system, flexible pipe conveyor system, and frame. results show significate difference on the collecting capacity, noise level and fuel consumption when rotation seed of the air mover shaft was varied. Other parameters such as collecting efficiency, air velocity, cracked grain percentage were significantly affected by varying rotational seed of the air mover shaft. The paddy suction transporter had a collecting efficiency of 86% with a collecting capacity of 560kg/hr. at a maximum rotational speed of centrifugal fan shaft of about 2700rpm with an engine of 8hp. The machine has an initial investment of 3,930,135/=. utilizing the machine for 2920 hours a year generating an income of 312,000,000/=. These needs a time recovery of about one year.
