在使用收割机收割大豆时,往住会造成螺旋推运器伸缩齿间严重堵塞,以致无法收割。人工清理费工、劳动强度大,而且解决不了问题。为什么会堵塞呢?这是因为大豆间混有杂草和其它豆棵,大豆又有较长的茎藤,易造成齿间缠绕。当拨禾轮把已割的豆棵拨入推运器输送区时,推运器的伸缩齿间隔插入百棵中,间断地把豆棵拨向输送室的喂入区。在此过程中,豆棵夹在齿间随推运器一起转动。当推运器转过一定角度,伸缩齿逐渐缩入螺旋筒,其中大部分豆棵沿切向被抛入倾斜输送室的喂入 When using harvesters to harvest soybeans, live-in will cause serious blockage of the auger’s retractable teeth, making it impossible to reap the harvest. Manually clean up workers, labor-intensive, and can not solve the problem. Why is it clogged? This is because the weeds are mixed with other beans in the soybeans, and the longer stems and vines in the soybeans can easily cause entanglement between the teeth. When the reel has been cut beans into the conveyor conveyor area, the retractor retractable teeth inserted into the interval, intermittently to the transfer of beans to the feeding room feeding zone. During this process, the bean clip rotates with the auger between the teeth. When the auger turns a certain angle, the telescopic teeth gradually shrink into the spiral cylinder, most of which are tangentially fed into the inclined transport chamber
