摘　　要：利用自行设计的板齿-栅格凹板组成的脱粒分离装置,在试验室内对水稻进行脱粒分离的单因素试验,通过计算和分析,总结出滚筒转速与喂入量的变化对脱粒损失、未脱损失、断穗率、糙米率、功率消耗以及茎秆破碎程度的影响规律和原因,指出该装置具有脱粒分离性能增强、脱不净率低、脱粒损失小、断穗少和脱出物中轻杂物含量较高的特点。Using self-designed plate teeth-grid intaglio of threshing and separating devices,in the laboratory for threshing rice separate single-factor test,by calculating and analysis,summarized roller speed and feed changes in the amount of threshing losses,the net rate of removal is not cut off ear,brown rice,and power consumption as well as the degree of influence stem broken the law and reason,the kinds of devices with enhanced separation performance of threshing, the net rate of removal is not low,threshing loss,broken ear less extrusion materials in the light of the characteristics of a high content of debris.
