摘要

A motorized stationary sorghum thresher was developed and tested. The sorghum thresher had the following components: frame, hopper, threshing unit, sieve, reciprocating mechanism, blower and the collecting trays. The performance variables investigated were: threshing efficiency, cleaning efficiency and cleaning loss at six threshing speeds (2.64, 3.64, 4.4, 5.03, 5.78 and 6.28 m/s), six air speeds (3.67, 4.67, 5.17, 5.47, 7.33 and 8.33 m/s), five sieve oscillation speed (0.59, 0.88, 1.47, 2.05 and 2.64 m/s) and five feed rates (492.86, 521.43, 640, 720 and 740 kg/hr). A 3~4 factorial experiment in a completely randomized block design was used to study the effects and interactions of variables on the threshing efficiency, cleaning efficiency and cleaning loss. The threshing efficiency varied between 99.94 and 99.96 %, cleaning efficiency ranged between 94.35 % and 96.14 % and the cleaning loss varied between 6.5 % and 9.91 % at the average sorghum moisture content of 8 % wb. All the main factors and their interactions were not statistically significant for the threshing efficiency, cleaning efficiency and cleaning loss.
