纵轴流锥型滚筒脱粒装置设计与试验

摘要

In order to lower power consumption, speed up the axial conveying of materials in threshing cylinder and improve the efficiency of machine cleaning of wheat breeding plot seed combine harvester, a longitudinal axial conical cylinder threshing unit with conical short-rasp-bar tooth structure was designed. The experimental results showed that the new device could speed up the conveying of materials in threshing cylinder and lower power consumption while threshing wheat, and the amount of wheat seed residued in the shell internal was little and there was no need to do manual clearing. The threshing unit can be applied to half-feeding breeding plot wheat seed combine harvester with cyclone air cleaning devices.%为了降低功耗,加快脱粒滚筒轴向物料输送速度,提高小区育种小麦种子收获机清机效率,设计了一种纵轴流锥型滚筒脱粒装置,滚筒采用锥型短纹杆一板齿结构.试验结果表明,该纵轴流锥型滚筒脱粒装置在作业时小麦脱粒混合物料轴向输送速度快、功耗低,罩壳内部种子残留量小,无需人工清机,适用于以旋风分离器为气流清选装置的半喂入式小区育种小麦种子收获机.
