Manually operated modified linseed crop thresher was developed from ergonomics considerations. Anthropometric data were taken in selected age subjects 25-40 years for male workers. Anthropometric data regarding body dimensions were obtained for male workers from SHUATS, Prayagraj. During the methods of threshing operation (thresher and traditional method) the working heart rate was recorded with proper technique and oxygen consumption rate, energy expenditure rate and body parts discomfort scoring was obtained. The heart rate, oxygen consumption, energy expenditure rate and BPDS were obtained in the mean value 115.19 beats/min, 0.63 l/min, 9.59 kJ/min and 44.93 for thresher operating whereas 127.56 beats/min, 0.77 l/min, 11.56 kJ/min and 55.43 for traditional method operating. |
