摘要

Preliminary testing of the developed picking aid was done in the field using various combinations of the picker end diameters (20, 25, 32 and 40 mm) and suction pressures (25, 30, 35, 40,45 and 50 mm of Hg) to study their effect on picking efficiency, trash content and output capacity. For assessing the parameters at a uniform level of suction pressures, extrapolation of the trend line had to be used to estimate picking efficiency, trash content and output capacity. Maximum picking efficiency of 96.3 % was achieved at a picker end diameter of 25 mm with a suction pressure of 45 mm of Hg. Minimum trash content of 0.65 % was observed at a picker end diameter of 20 mm with suction pressure of 30 mm of Hg. Maximum output capacity of 6.25 kg/h was achieved at a picker end diameter of 25 mm with suction pressure of 45 mm of Hg. The picking aid was then evalu ated for long term field trials with the optimized picker end diameter (25 mm) at varying suction pressures (35, 40, 45 and 50 mm of Hg) for two stages of picking. Though the picking efficiency and output capacity was maximum at 50 mm suction pressure for the first picking, trash content increased at this suction pressure. However, minimum trash content of 5.7 % was obtained at 35 mm of Hg with a picking efficiency of 93.9 % and output capacity of 4.2 kg/h. Similarly, for the second stage of picking, minimum trash content of 4.39 % was at 35 mm suction pressure with picking efficiency of 92.8 % and output capacity of 4.01 kg/h.
