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 crop from the hoist feeding bucket, lift it through the hoist, and enter the wind screening part through the hoist feeding pipe. The material is air-selected and separated twice in the grain-in and grain-out boxes that are screened by the wind. The light impurities are separated and discharged out of the machine through the dust collector and the trash auger; the large impurities and small impurities are screened and discharged through the trash pipe. The other good materials are screened out by the wind to the grain box and enter the specific gravity selection platform, and the materials pass The layering is carried out by the effect of wind, and the lighter materials (grate, mildew) pass through the hopper discharge machine, and the full materials enter the screening classifier (optional), and the materials are divided into 3-5 grades according to the geometric size of the materials (User requirements) Discharge out of the machine through the respective outlets of the discharging box.

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 food tank and the grain box for two wind selection separation, the light impurities separated, through the dust remover and chops Out of the machine, large impurities and small impurities after screening through the drainage pipe discharge, the rest of the better material through the wind screening out of the grain box into the gravity selection platform, the material through the role of the wind layering, lighter materials (箅, mold) through the removal of the machine in addition to the hybrid, Full material into the screening grader (optional), according to the geometry of the material will be divided into 3-5 levels (user requirements) through the discharge bin of their respective exits are discharged from the machine.

5. working procedure: feed the crop from the elevator feeding bucket, lift it through the hoist, and enter the air screening section through the elevator feeding pipe, The materials are separated by air separation in the air filter feed tank and the outlet bin, and light impurities are separated, except for the dust collector and the discharge auger; after screening, the large impurities and small impurities are discharged through the discharge pipe, and the other better materials are screened out of the grain tank through the air to enter the specific gravity fine selection platform, and the materials are layered by the action of wind. The lighter materials (grates, mildew) are removed by removing the light impurities Outside the hopper discharge machine, the full material enters the screening classifier (optional), and the material is divided into 3-5 grades (required by the user) according to the geometric dimension of the material, and then discharged out of the machine through the outlet of the discharge box.<br>
