使用E-512联合收割机收割亩产400斤以上的小麦时,会出现严重的跑粮现象。经调查发现,跑粮是由于使用调整不当和清粮机构转速不够引起的。现将跑粮部位、原因分析和预防措施介绍如下,供参考。跑粮的部位 E-512联合收割机跑粮主要在逐稿器上和消选机构的上筛两个部位。跑粮的原因 1.逐稿器前上方安装的挡帘调得太高,或在排除故障时,将挡帘卷起,未及时放下。逐稿器前上方安装的可调胶皮挡帘是用来阻滞茎秆运动的,以便使混杂在茎秆内的籽粒,有充足的时间分离出来。如果挡帘调得太高或卷起来,茎秆就会毫不受阻地排出,使籽粒来不及分离,就随同茎秆一起排出了。 2.在排除故障时,由于人进入键箱上部,将筛孔上的扇形舌踏下去,使筛孔变小。这样,从茎秆中分离出的籽粒,难以从筛孔漏下,而随同茎秆排出。 3.收割含杂草多的作物时,杂草缠挂在键面上,堵住键筛孔,使籽粒不能漏下而跑掉。
When E-512 harvesters harvest more than 400 pounds of wheat per mu, serious run-down can occur. After investigation, run grain is due to improper use of the adjustment and insufficient speed of the grain clearing mechanism. Running grain now part of the reasons analysis and preventive measures are as follows, for reference. Part of the running grain E-512 combine harvester running grain mainly in the draftsman and the selection of institutions on the sieve two parts. Reasons for running grain 1. Curtains installed above the top of the strawboard must be adjusted too high or the curtains should be rolled up and not promptly dropped when troubleshooting. Adjustable rubber curtains installed on the top of the strawbin are used to stop the movement of the stalks in order to allow enough time to separate the grains mixed in the stalks. If the curtain is adjusted too high or rolled up, the stalks will be discharged without obstruction, so that the grain can not be separated, it is discharged along with the stalks. 2. In the troubleshooting, because people into the upper part of the key box, the fan on the sieve tongue, so that the smaller sieve. In this way, the grain separated from the stalk is difficult to escape from the sieve and is discharged along with the stalk. 3. Reaping weed-rich crops, weeds wrapped around the key surface, blocking the key sieve, so that the grain can not drain and run away.
