| Popis: | An experiment was conducted to study the effect of threshing speed and feeding weights on the maize threshing machine efficiency, threshing speed of the threshing machine included 270, 470 and 570 rpm, the feeding weights of the threshing included 4, 7 and 10 kg, in the specific productivity, specific energy consumed, threshing efficiency and broken cobs. The results showed that increasing the speed of threshing unit from 270 to 470 then to 670 rpm had a significant effect on specific productivity, specific energy consumed, threshing efficiency and broken cobs. Increasing the threshing feeding weights from 4 to 7 then 10 kg led to increasing the specific productivity along with a decreasing in the specific energy consumed, threshing efficiency and broken cobs .The highest specific productivity was 7.98 kg/kw.h. The least specific energy consumed 0.127 kwh/kg at the threshing speed of 470 rpm and the feeding weights 10 kg. While the threshing efficiency was 100% with broken cobs of 0%, at 470 rpm threshing speed for all of the feeding weights. |
