In view of the shortage of diesel/ kerosene in the villages and the electricity-crisis, Mr.Pooranlal Kushwaha developed the bullock-driven water lifting pump so that the farmers could use their existing resources and get sufficient water for irrigation and domestic work.
The pump has a gear box, crown gear teeth (24” diameter), pinion teeth (4” diameter), gear 70 teeth (12“ diameter), pinion 20 teeth (2” diameter), gear shaft, bearings, shaft, pulley, V belt, centrifugal pump ( without electric motor) 3 hp. and yoke ( 3 m long)
The major function of the Pooran bullock-driven water lift pump is to convert the bullock energy into mechanical energy. The main component is the reduction gear unit, which transmits power to the system. The main conversion unit, which consists of an old chaff cutter gearbox and the gear reduction unit are installed on a suitable foundation.
The bullock’s average speed is 3 rpm. The 14” diameter pulley converts the rotation to 10 rpm. The 4” diameter pulley further increases the rotation to 350 rpm. The 25” diameter pulley fixed on 4” diameter pulley further increases it to 1400 rpm.
The pump provides an output equivalent to that of a 3hp. electrically-operated centrifugal pump.
The bullock-drawn centrifugal pump can be operated with a pair of bullocks without causing them much fatigue. A reduction gear unit and a conversion unit (the main components enabling conversion of bullock energy into mechanical energy) are employed. The pulleys of several dimensions which are employed serve to increase the speed from 3 rpm (by bullocks) to a maximum of 1400 rpm, necessary for lifting water by pump. The discharge of this pump, which is equivalent to a 3 hp. electrically-operated centrifugal pump, can be increased according to suitable power transmission design. There is scope for using the bullock-drawn unit in other agriculture processes, as a chaff cutter or groundnut decorticator during the idle period. |
