顿河—1500联合收割机在我团已使用三年,在使用中首先遇到的是三台收割机都有不同程度的在摆环机构——摆环箱出了问题.造成箱盖螺栓旷动,无法紧固,最后导致箱盖破裂,迫使停止作业.针对上述情况,我们对摆环箱及盖进行改装,改装后经二个夏收,三年秋收试用,效果很好.其中有一台车共收割9800亩地,收获粮食490万公斤.具体作法如下:1.对摆环箱进行拆检.拆检后,发现“U”型叉轴上下窜动.由于上、下窜动与“U”轴垂直的传动轴形成一个扭力,使摆环箱盖损坏.为此我们将原机铸造的摆环箱盖,改制成熟铁钢件摆环箱盖.
Dayton -1500 combine harvester in my group has been used for three years, the first encounter in the use of three harvesters have varying degrees of swinging mechanism - swing ring box out of the problem.
