叶尼赛-1200联合收割机具有马力强劲、行走可靠、脱粒彻底等优点,可进行谷物、豆类、大颗粒作物的联合及分段收割,且工作效率可观。但也存在一定的缺点,由于该机采用双滚筒式脱粒装置,脱出物较碎,清选面积较小,在产量较高地段收割时,易出现因清选不过来而造成的跑粮现象。为解决上述问题,我 With the advantages of strong horsepower, reliable running, threshing thoroughly, etc., the combination of the grain, beans and large grain crops can be harvested at the Yenisei 1200 Combine Harvester and the work efficiency is considerable. However, there are also some shortcomings. Due to the double-roller threshing device, the projectiles are more crushed and the clearing area is smaller. When harvesting in the higher yielding section, the running grain phenomenon easily occurs due to the clearance. To solve the above problem, I
