    摘要:

    利用小麦扶持脱粒装置试验台,以脱粒损失率为指标进行了滚筒转速、板齿倾角单因素试验,初步确定了脱粒滚筒转速和板齿倾角。在此基础上,以脱粒损失率和含杂率为指标,进行了滚筒转速、筛孔尺寸和脱粒间隙三因素正交试验和滚筒转速、脱粒间隙两因素回归试验,优化确定了该扶持脱粒装置的最佳参数组合。当筛孔尺寸为14 mm、板齿倾角为0°、脱粒间隙为18.5 mm、滚筒转速为927 r/min、滚筒长度为700 mm时,脱粒损失率和含杂率分别为2.71%和19.20%。

    Abstract:

    By using the self-designed threshing apparatus test- bed, single- factor tests of roller- speed and tooth- angle were carried out and the values of these two factors were obtained. On this basis, the three factors orthogonal test, including the speed of the roller, the mesh aperture and the thresh gap, was researched. The two factors regression experiment, including the roller speed and the thresh gap, was also studied. Optimum parameter combination of threshing apparatus was obtained. When the mesh aperture was 14 mm, tooth angle was 0°, thresh gap was 18.5 mm, roller speed was 927 r/min and roller length was 700 mm, the threshing loss rate was 2.71% and the trash content was 19.20%.
