通过作业质量的检查可以大致判断需调整的部位,具体方法如下: 1 脱粒不净。主要原因是滚筒转速低、脱粒间隙大或两侧的间隙不一致、喂入不均匀、作物太湿等。可根据收割时的具体情况分析进一步确定。 2 破碎率过大,碎茎秆使筛子超负荷且在筛子上籽粒损失过大。其原因是由于滚筒转速过高及脱粒间隙太小所致。可先调大割台的脱粒间隙,并注意间隙是否一致,局部地方间隙是否过小。调大间隙
By checking the quality of operations can be roughly judged to adjust the site, the specific method is as follows: 1 Threshing is not net. The main reason is the drum speed is low, threshing gap or gap on both sides of the inconsistent feed uneven, crops are too wet. According to the specific circumstances of the harvest to further determine the analysis. 2 Broken rate is too large, broken stem overload sieve and grain loss on the sieve too large. The reason is due to the drum speed is too high and threshing gap is too small. You can adjust the threshing gap of the main header and pay attention to whether the gaps are the same or not, and whether the local gaps are too small. Increase the gap
