Abstract:
Annual use of draught animals needs to be increased to reduce the burden of maintenance cost of bullocks, which can be possible by using post-harvest machines in rotary mode. Performance evaluation of a bullock operated rotary gear transmission system was conducted for paddy threshing by a hold-on type paddy thresher with respect to various parameters namely rotary system, physiological and machine parameters at three different levels of working radii in rotary mode. The lowest draft requirement, highest speed of operation of bullocks and highest thresher drum speed were observed to be 454.34 N, 0.73 m sec-1 and 435.45 rpm respectively at 3.8 m working radius. At this working radius, the physiological parameters of working bullocks such as pulse rate, respiration rate and body temperature were found to be within sustainable loading capacity of the bullocks. The machine parameters like threshing capacity and threshing efficiency were observed to be highest of 136.87 kgh-1 and 94.34 per cent respectively at a working radius of 3.8 m. The average mechanical transmission efficiency and performance index of the rotary system were found to be 64.84 per cent and 12.36, respectively.
