[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0016] See also Figure 1A bidirectionally adjustable chute impurity removal device comprises a chute body 1, a bellows 2, a fan 3, and a damper 4. The chute body is welded from sheet metal and has a sloped cross-section. A tuyere is located at the bottom of the chute, which is assembled with the damper. The damper is an adjustable connecting rod mechanism comprising multiple blades, a shaft, a connecting rod, and a handle. The handle can be rotated to adjust the blade angle, thereby adjusting the air volume.

[0017] The bellows 2 includes a bellows body and an adjustment plate, which is installed on the top panel in the vertical direction of the bottom air outlet surface of the slide pipe body 1, connecting the slide pipe body 1 and the fan 3 to achieve gas circulation.

[0018] The fan 3 is located on the top of the wind box 2 and is connected to the dust removal pipe to discharge impurities and dust outside the room.

[0019] See also Figure 1 Grain flows from top to bottom along the inner wall of the bottom of the chute body, achieving a separated state when passing through the cross-sectional slope. In this separated state, external air, under the action of the fan, enters through the damper 4 at the bottom of the chute body 1, penetrates the grain layer, and carries away impurities and dust, and is then discharged through the bellows 2 and fan 3. During the impurity removal process, the blade angle of the damper 4 and the air outlet area of ​​the bellows 2 can be adjusted respectively to change the air volume and pressure required for impurity removal, achieving the best impurity removal effect while ensuring that the grain is not carried out.

[0020] refer to Figure 2 The figure shows a schematic diagram of the slide pipe body 1, which mainly includes a lower base plate 7, an upper base plate 6, an air guide plate 5 and a cover plate 8. All of them are bent from plates and then formed by welding. The bottom is made of stainless steel to increase wear resistance.

[0021] The upper base plate 6 and the lower base plate 7 shown in the figure form a fault at the position of the wind guide plate 5 shown in the figure. The two have the same inclination angle but are not coplanar. The lower base plate 7 is located below the fault, forming a natural drop.

[0022] After the gas enters through the air door, it penetrates the grain layer from bottom to top under the action of the air guide plate. The contact area between the gas and the grain is larger, and the impurity removal effect is better and more significant.

[0023] See also Figure 3 The figure shows that the bellows 2 includes a bellows body 9 and an adjustment plate 10. The bellows body is a sheet metal part, welded into shape, with mesh holes on both sides and a fan mounting hole on the top surface for connecting the fan.
