小麦联合收割机在作业中,常因滚筒堵塞导致作业进度下降。其原因:喂入量过大;脱粒装置上的滚筒转速低,滚筒凹板间的间隙太小;小麦秸秆潮湿等。根据上述原因,可采取以下对策:1.适当降低小麦联合收割机的前进速度,以减少滚筒、凹板间的秸秆输入量。2.适当提高麦茬高度,缩短割下农 Wheat combine harvester in operation, often due to blockage caused by the roller job progress decreased. The reason: the amount of feed is too large; threshing device drum speed is low, the gap between the drum concave plate is too small; wet wheat straw and so on. Based on the above reasons, the following measures can be taken: 1. Appropriate to reduce the speed of wheat combine harvester to reduce the amount of straw between the drum, concave plate input. 2. Appropriate to raise the height of stubble, cut short cut farming
