摘　　要：提出了一种喂人量为4～5ks／s的履带式切纵流双滚筒联合收获机的总体配置方案，论述了切纵流双滚筒脱粒分离装置切流脱粒滚筒、切流凹板、过渡口、纵轴流滚筒和纵轴流凹板等结构与运动参数的设计。田间试验与性能测试表明：该机收获水稻时喂入量达到4．86kg／s时，整机损失率为1．47％，破碎率为0．2％，各项技术指标达到了设计要求。With the development of rice harvesting with large scale in China, high-efficiency of combine is more and more important. In order to satisfy the urgent demand of high-efficiency combine, the overall structure of a new crawler-type combine with a feed rate of 4 - 5 kg/s was proposed and the combinational threshing and separating unit with a transverse tangential cylinder and axial rotor was designed. The design focused on the designing process of structural and operational parameters of tansverse tangential cylinder tangential concave, transition section between tansverse tangential concave and rotor concave, axial rotor and concave. Field test showed that the total loss was 1.47% and the damage rate was 0.2% , when the feed rate was 4.86 kg/s, which met the demands of the design.
