摘　　要：针对小型水稻联合收割机的气流清选系统进行了研究。通过设计计算获得了初始设计参数,以此为依据制作样机并在田间进行了试验。试验结果表明计算和实际有较大差异。在原设计基础上更改了一些敏感参数,再次试验获得较好的清选效果,清洁率和损失率均达到要求。The cleaning system for small combine harvester was studied in the paper. The initial design parame ters were obtained through computation and the prototype was manufactured based on the data. The field experiment demonstrated that there was a large difference between the computation and actual use. Some parameters were mod ified and a better effect of the cleaning system was achieved by another field experiment with cleaning rate and lose rate meeting the requirements.
