我团场使用的zMAJ—161收割机的割台部分,普遍存在着两个问题。一是茎杆在螺旋推运器处堆积,造成喂入量不均匀,致使滚筒堵塞、脱粒不净,给清选也带来不利。二是当机车割速稍高时,个别作物被割台推过去,割不下来,造成割茬高低不齐、收割不净。由于以上两种原因,一般亩产在400—500斤时,机车收割速度只能控制在3公里/小时左右,不利于该机效率的发挥。 There are two common problems with the header section of the zMAJ-161 harvester that I use in my field. First, the accumulation of stalks at the auger, resulting in uneven feeding, resulting in drum clogging, threshing is not net, also brought adverse to the election. Second, when the locomotive cut-off speed is slightly higher, individual crops are pushed over the header, can not cut, resulting in uneven cutting, harvesting is not net. Due to the above two reasons, the general mu produce 400-500 kg, the locomotive harvesting speed can only be controlled at 3 km / h, is not conducive to the efficiency of the aircraft.
