今年麦收,我场一台东风-5型联合收割机在作业中,一条底筛传动链因润滑不良突然断裂,使筛体停止抖动,逐稿器送来的麦粒不能通过底筛送往粮仓。这时,只有极少量的麦粒被送往粮仓,但驾驶员没有及时发现,又继续工作了3～4分钟,底筛上积存了大量的麦粒及颖壳。这样,逐稿器运动时,不断与积存物碰撞,致使逐稿器严重变形,逐稿器之间相互摩擦碰撞,使两个逐稿器折断。当时故障表现:机体剧烈抖动,并伴有“咕咚”、“咕咚”的响声,只有极少量的麦粒进入粮仓。这一事故提醒我们,收割机机体庞大,结构复杂,在使用中一定要注意勤看、勤听、勤检查、勤保养。
This year, wheat harvest, my field a DF-5 combine harvester in operation, a bottom sieve chain due to poor lubrication suddenly broken, so that sieve body to stop jitter, by the bottom of the grain sent to the silo can not be sent to the silo . At this moment, only a very small amount of grain was taken to the granaries, but the driver did not find out in time and continued to work for 3 to 4 minutes. A large amount of grains and glume shells were accumulated on the bottom sieve. In this way, during the motion of the paper organizer, the collision with the accumulated objects is continuously caused, which leads to the serious deformation of the paper-throwing device and the friction between the paper-strikers and the collision of the paper-writers. At that time the fault performance: the body fierce jitter, accompanied by “Gudong ”, “Gudong ” sound, only a very small amount of grain into the granary. This accident reminds us that harvester body is huge, complex structure, in use must pay attention to Qin, Qin listen, ground inspection, ground maintenance.
