针对稻秸秆粉碎装置对含水率较高的青秸秆工作时会出现粉碎不充分、机具堵塞、还田不均匀等问题,设计了一种悬挂在联合收割机后面的新型稻秸秆粉碎还田装置。该装置采用滚刀式的切割方式,设置有输送绞龙和专门的还田装置,采用结构设计的方式提高秸秆还田机具的秸秆粉碎长度合格率,降低秸秆还田不均匀度,对装置完成研制并对其进行了台架试验。

Aiming at the problem that the straw crushing device works on the green stalk with high water content,the crushing is not enough,the machine is clogged,and straw returning in field is uneven,a new type of straw crushing and returning device hanging behind the combine harvester is designed.The device adopts a hob-type cutting method,provided with a conveying auger and a special returning device,and adopts a structural design method to improve the qualified rate of the straw crushing length of the straw returning machine and reduce the un...
