摘　　要：以一种钉齿脱粒元件为试验对象,以喂入量、滚筒转速和脱粒间隙为因素,以籽粒脱净率为评价指标进行正交试验。试验结果表明:对籽粒脱净率的影响程度为喂入量>滚筒转速>脱粒间隙;最佳工作参数为喂入量5.5 kg/s,滚筒转速950 r/min,脱粒间隙20 mm(入口)和15 mm(出口)。In this paper,a kind of threshing element of nail teeth was developed as the test object,and the orthogonal test was carried out with the feed rate,drum speed and threshing gap as the factors,and the grain threshing rate as the evaluation index.The results show that:The effect on grain threshing rate is feeding>drum speed>threshing gap;The best working parameters are feeding 5.5 kg/s,drum speed 950 r/min,threshing gap 20 mm(inlet)and 15 mm(outlet).
