摘　　要：为了研究含杂率对清选环节的影响规律,以风机转速、风机倾角和曲柄转速为试验因素,以含杂率作为评价指标,在清选试验台上进行水稻清选试验,得到回归模型以及影响含杂率的主因素,为风筛式清选装置的设计及制造提供依据。In order to study the impact law on dirt percentage of air-and-screen cleaning device, as experiment factors with fan rotational speed, fan rake angle, crank rotational speed and dirt percentage, as the evaluation index with dirt- percentage,experimental study in the cleaning test-bed, get the regression model,and analysis the main causes of affec- ting the dirt percentage, which has important meaning to guide design and manufactory of cleaning device.

关 键 词：清选装置 风筛式 含杂率
