1987年,我场刚购进的6台金马1065自走式联合收割机中的4台,在收割水稻时钉齿滚筒先后被砸坏7次,而每台机子的作业量不足800亩。凹齿板,杂余均布搅龙、凹板、滚筒轴及机壳也有不同程度的损坏。下面就滚筒被砸原因予以探讨并提出修复方案。 In 1987, four of the 6 Jinma 1065 self-propelled combine harvesters that I just bought in the market had been smashed 7 times during the harvesting of rice while the workload of each machine was less than 800 mu. Recessed teeth, heterogeneous uniform auger, concave plate, roller shaft and chassis also have different degrees of damage. Here to smash the reasons for the drum to be discussed and put forward the restoration program.
