5．工作程序：将作物从提升机喂入斗喂入，通过提升机提升，经提升机输料管

5. Working procedure: Feed the crops from the hoist feeding bucket, lift them through the hoist, and enter the wind screening part through the hoist feeding pipe. The materials are air-selected and separated twice in the grain-in and grain-out boxes that are screened by the wind. Light impurities are separated and discharged out of the machine through a dust collector and agitator;

5． Working procedures: the crop from the lifter feed into the bucket feed, through the lifter lift, by the lifter feed tube into the wind screening part, the material in the wind screening of the feed tank and the grain box for two wind selection separation, the separation of light impurities, through the dust remover and the discharge of the dragon out of the machine;

5. Working procedure: feed the crop from the feeding bucket of the elevator, lift it through the elevator, and enter the air screening part through the conveying pipe of the elevator. The material is separated by twice air separation in the grain inlet box and the grain outlet box of the air screening, so as to separate the light impurities, and discharge them out of the machine through the dust collector and the impurity removal auger;<br>
