一、杂余推运器的堵塞问题。 C-12M联合收割机在收割黄豆、田菁、高粱等作物时,杂余推运器常发生堵塞,如果发现不及时,将会损坏皮带、推运器搅龙片和链板,影响收割机工作效率。杂余推运器堵塞的原因和故障排除方法如下。 1.第一清洁室下筛孔径选用不当。此筛孔径过小,会增加黄豆破碎率;过大,颗粒、杂余分离不清,加重杂余推运器负荷,造成堵塞。所以此筛应选用10毫米孔径为宜。 2.风向调整不当,风量过小。应将导向板风向调
First, the congestion jumped blocker problem. C-12M Combine harvester In the harvest of soybeans, Sesbania, sorghum and other crops, the residue often blockage, if not found, it will damage the belt, auger and the chain board, affecting the harvester Work efficiency. The reasons for congestion blocker and troubleshooting are as follows. 1. The first clean room under sieve aperture improper use. This sieve pore size is too small, will increase the rate of soybean crushing; too large, particles, impurities separation is not clear, increase the load of residual conveyor, causing blockage. So this screen should use 10 mm aperture is appropriate. 2. Improper adjustment of the wind, the air flow is too small. Wind direction of the guide plate should be adjusted
