由于牵引式联合收获机的低割性能较自走式联合收获机为优,所以它是我们目前豆收的主要机型。又由于大豆是一种吸湿性很强,对气候于湿变化反应很灵敏的作物,加上牵引式联合收获机脱粒装置的设计缺陷,豆收中一般破碎都较重,尤其干旱年份的豆收后期,有的单位破碎率高达25%以上,这不但使大豆产量减少,又降 Because of its low cutting performance, the Trailed Combine Harvester is better than the self-propelled Combine Harvester so it is the main model we currently receive from beans. And because soybeans are highly hygroscopic, sensitive to climate changes in wet crops, coupled with the design of traction combined threshing device defects, the beans are generally broken in the harvest are heavier, especially in the dry year of the beans harvest Later, some units broken rate of up to 25% or more, which not only to reduce soybean production, down
