风筛式清选装置功耗的试验研究

摘要

为了研究风筛式清选装置功耗的影响规律,以风机转速、风机倾角、曲柄转速为试验因素,以功耗作为评价指标,在清选试验台上进行水稻清选试验,得到回归模型,分析了影响功耗的主要成因,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 of power consumption of air-and-screen cleaning device, the fan rotational speed, fan rake angle and crank rotational speed were taken as the experimental factors, and power consumption as the evaluation index. Rice cleaning test was carried out on the cleaning test-bed. The regression model was built, and the main cause of affecting the power was analyzed and provided as the basis for design and manufactory of air-and-screen cleaning device.
