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。
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 crawlertype combine with a feed rate of 7 ~ 9kg / 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 8.57 kg / s,which met the demands of the design.
