Abstract:

A double chain-sprocket winnower was developed to reduce the hand drudgery and increase the efficiency of the winnower. The winnower consisted of two stage chain and sprocket transmission system with an overall speed increment ratio of 6. The performance and ergonomical evaluation of the developed winnower was carried out using anemometer and pulse oximeter, respectively. Both the evaluation parameters were compared with the pinion driven winnower and single chain-sprocket type winnower.The double chain sprocket developed highest wind speed with an average wind speed of 5.92 m/s followed by pinion driven type winnower with an average wind speed of 4.66 m/s and single chain sprocket type winnower with an average wind speed of 4.08 m/s. Further, the double chain sprocket required lowest energy expenditure with an average value of 13.23 kJ/min, whereas the energy required for single chain sprocket type and pinion driven type winnower was 15.76 kJ/min. and 17.38 kJ/min, respectively. The overall weight of the machine was only 23.5 kg and the production cost of the developed winnower was Rs. 4492 making it affordable for small and marginal farmers.
