Abstract:
Harvesting of drumstick pods by traditional methods such as use of hook and bamboo, climbing labour on tree is difficult task. In order to reduce losses during harvesting of drumstick and to maintain fruit quality, judgmental visibility in selective cutting, and damage to the drumstick during the harvesting, long working hours and uncomfortable posture of worker, a manually operated Cutter was developed. The device consisted of clutch lever, a clutch wire, an extension mechanism, a cutting mechanism. During operation, it was observed that field capacity of manually operated drumstick cutter was 0.0072 ha/hr. Anthropometric data of age group operators of (25-40 years) were determined. Heart rate, oxygen consumption rate, energy expenditure rate and body part discomfort score of physiological and postural parameters of age groups were determined during working on manually operated drumstick cutter at agriculture working field. In Ergonomic evaluation Heart rate, oxygen consumption rate, energy expenditure rate and body part discomfort score were varied from 98 to 120 b/min, 0.450 to 0.670 l/min, 10 to 17 kl/min and 22.12 to 49.43, respectively for age groups (20 to 35) years of workers during working on manually operated drumstick cutter. Maximum of heart rate, oxygen consumption rate, energy expenditure rate and body part discomfort score were found 120 b/min, 0.70 l/min, 17 kJ/min, 49.43, for worker age of 31-35 year, on manually operated drumstick cutter. Minimum of heart rate, oxygen consumption rate, energy expenditure rate and body part discomfort score were found 98 b/min, 0.450 l/min, 10 kJ/min, 22.12, for worker age group of 20 to 23 years on manually operated drumstick cutter.
