| 摘 要： | 在切纵流双滚筒脱粒分离性能试验装置上，进行喂入量为6kg／s的水稻脱粒分离性能试验，研究其最佳脱粒分离的结构参数和运动参数。试验结果表明，切纵流双滚筒联合收割机收获水稻的最佳组合方式为：切流滚筒间隙27mm，纵轴流滚筒间隙14mm，切流滚筒线速度为25．9 5m/s，纵轴流滚筒线速度为28．23m/s，纵轴流滚筒齿杆间距为140mm。并对切流滚筒脱粒分离籽粒的轴向分布、纵轴流滚筒脱粒分离籽粒的轴向和径向分布进行了研究，为后续清选装置的研究提供了设计依据。

| Abstract: | The performance of threshing and separation of tangential-longitudinal combine at the feed rate 6kg/s of rice was tested and the optimal structural parameters and operation parameters were explored. Test results showed that when tangential concave-drum gap was 27mm, longitudinal concave-drum gap was 14mm, linear velocity of tangential drum and longitudinal drum were 25.95m/s and 28.23m/s respectively, and the space of spike of longitudinal drum was 140mm, the tangential- longitudinal combine obtained optimal performance of threshing and separation. Grain distribution under tangential drum and longitudinal drum along axial direction and radial direction were analyzed, which provided design basis for cleaning device. |
