摘 要: | 为满足我国现阶段高产水稻的高效收获要求,提出了一种喂入量为7~9kg的履带式新型斜置切纵流双滚筒联合收获机的总体配置方案,论述了斜置切纵流双滚筒脱粒分离装置中切流脱粒滚筒、切流凹板筛、锥形螺旋过渡喂入装置、斜置纵轴流滚筒和纵轴流凹板筛的结构设计,确定了各个工作部件的工作参数。田间试验表明:该装置在收获水稻喂入量为8.57kg/s时,脱粒损失率为0.79%,籽粒破碎率为0.1%,各项性能指标均达到设计要求;同时,在喂入量增大时,该装置各工作部件功耗较为平稳,适应性较强。

Abstract: | 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 7~9 kg/s was proposed and the combinational threshing and separating unit of oblique tangential-longitudinal combine was designed .The design focused on the designing process of structural and operational parameters of tansverse tangential cylinder tangential concave , conical spiral transition device , axial rotor and concave . And determine the working parameters .Field test showed that the total loss was 0.79%, the damage rate was 0.3%and the impurity content was 0.8%,when the feed rate was 8.57kg/s,which met the demands of the design . |
