出现脱粒机滚筒爆炸、机手断指、甚至机毁人亡事故的主要原因:1.超速运转,规定转速下的平衡遭到破坏,部分机件受力过大,滚筒变形爆炸;2.运转中组成滚筒的零件折断、脱落、松动、移位,产生了碰撞和破坏性的连锁反应;3.脱粒时喂入深度过大,或抓握秸秆太紧,把手拽了进去。因此,务必认真采取预防措施。 1.必须按随机说明书选配动力机及其皮带轮,不能提高滚筒转 The emergence of threshing machine drum explosion, finger broken hands, or even crash the main reasons for the accident: 1. Overspeed, the provisions under the balance of speed has been destroyed, part of the mechanical stress is too large, the drum deformation and explosion; In the composition of the cylinder parts broken off, off, loose, shift, resulting in a collision and destructive chain reaction; 3 throat feed depth is too large, or grasp the straw too tight, dragged into it. Therefore, be sure to take precautions carefully. 1. Must follow the random manual matching power machine and its pulley, can not increase the drum
