脱粒机在脱粒作业中,常发生滚筒被茎秆堵塞的故障,可以用以下的方法预防: 1.直径小的滚筒,在脱粒水稻或潮湿的的小麦及长秸秆作物时,容易缠草。因此应选购直径较大的滚筒。小直径滚筒脱粒机脱粒小麦时,可将麦头切下脱粒,不要脱秸秆潮湿的作物。 2.滚筒转速不能过低或过高。过低,滚筒易堵塞,过高,籽粒易破碎,且耗用的能量多。一般以满足作物脱粒的速度为好。如脱小麦,以每分钟1650～1950转为好;脱粒籼稻以每分钟1450～1550为好;脱粒梗稻以每分种1550～1800转为好。
Threshing machine in the threshing operation, often occur drum stalk blocked failure, can be prevented by the following methods: 1. Small diameter drum, threshing paddy or wet wheat and long straw crops, easy to wrap grass. So should buy a larger diameter roller. Small diameter drum thresher Thresh wheat, threshing the wheat head, do not take off the straw wet crops. 2 drum speed can not be too low or too high. Too low, drum easily blocked, too high, easy to break the grain, and energy consumption. Generally to meet the crop threshing speed as well. Such as wheat off, to 1650 ~ 1950 turn into good; threshed indica to 1450 ~ 1550 per minute is good; threshed stems to 1550 ~ 1800 per minute turn for the better.
