摘　　要：利用谷子半喂入脱粒装置试验台,以脱不净率为指标进行了滚筒转速的单因素试验;以滚筒碾压段接料籽粒质量分数和杂余籽粒率为指标,进行了碾压辊状态的对比试验。在此基础上,以脱粒损失率、含杂率和杂余籽粒率为指标,进行了滚筒转速、脱粒间隙、凹板筛条间隙的正交试验和回归试验,优化得到该半喂入脱粒装置的最优参数组合。在试验条件下,当碾压辊可转动、滚筒转速为620 r/min、脱粒间隙为12.5 mm、凹板筛条间隙为9 mm时,脱粒损失率和含杂率分别达到0.91%和10.91%。By using the millet head-feed threshing unit test-bed,the single factor test of roller speed was carried out with the index of threshing without a net rate. The contrast test of the state of grinding rollers was carried out with the index of kernel mass fraction and doped kernel rate in grind stage. On the basis,taking the threshing loss rate,impurity rate and doped kernel rate as indexes,the orthogonal test and regression test on the roller speed,the threshing gap and the concave mesh aperture were carried out. The optimal parameter combinations of the millet head-feed threshing unit were obtained. When the grinding rollers are rotatable,and the roller speed,the threshing gap and the concave mesh aperture is 620 r / min,12. 5 mm,and 9 mm respectively,the threshing loss rate and the impurity rate is 0. 91% and 10. 91%,respectively.
