A discharge port 8 of a square structure intersecting with the discharge port 8 is provided on the bottom surface of the transition box 6. The square structure can form a horizontal structure when wheat is discharged into the discharge port 8, thereby increasing the contact area with the wind, and guide bases are also provided at both ends of the inner wall of the transition box 6;

[0025] A debris removal barrel 9 is provided below the discharge port 8, and both ends of the bottom surface of the debris removal barrel 9 are supported and connected by arc seats 23 respectively. A through groove 10 adapted to the inner wall of the discharge port 8 is provided on the debris removal barrel 9, and a regulating device capable of controlling the flow rate is provided in the through groove 10. An air inlet pipe 21 intersecting the air inlet pipe 21 is provided on one end surface of the debris removal barrel 9, and a collecting bag 22 is sleeved at the opening on the other side. A collecting port 7 is also provided on the bottom surface of the debris removal barrel 9 at a position corresponding to the through groove 10.

[0026] Through the above structure, the air inlet pipe 21 is connected to an external fan, so that when the wheat falls into the impurity removal barrel 9, the light impurities inside can be blown into the collecting bag 22, thereby performing air separation and impurity removal operations on the wheat.

[0027] like Figure 2 and Figure 4 As shown, the regulating device comprises a sealing plate 11, a sliding seat 15 and an adjusting screw 16. The sealing plates 11 that can slide left and right are symmetrically connected on the top wall of the impurity removal cylinder 9 corresponding to the two ends of the through slot 10. A groove body 14 is opened along the axial direction of the top surface of the impurity removal cylinder 9 corresponding to the middle position of each sealing plate 11. The sliding seat 15 fixedly connected to the sealing plate 11 is penetrated in the groove body 14. In this way, under the action of external force, the sliding seat 15 can be driven to move left and right for adjustment, and the sealing plate 11 can be driven to move left and right for adjustment, so as to effectively adjust the flow rate at the through slot 10.

[0030] In specific use, first connect the air inlet pipe 21 to the external fan, then inject the wheat into the storage barrel 3, and then adjust the opening size of the through groove 10 by sliding the sealing plates 11 at both ends left and right. After the adjustment is completed, the sliding seat 15 is positioned with the cooperation of the locking nut 19 and the adjusting screw 16, and the adjusted sealing plate 11 is positioned at the same time, so as to effectively adjust the flow at the discharge port 8. Then start the external fan, open the switch valve 5 to allow the wheat to flow downward into the transition box 6, and then, with the cooperation of the square-structured discharge port 8 and the through groove 10, the wheat is made to flow into the impurity removal barrel 9 in a planar structure. Under the action of the fan and the air inlet pipe 21, wind force is introduced into the impurity removal barrel 9, and the light impurities in the wheat are blown into the collecting bag 22. At the same time, the wheat flows out from the collecting port 7 for collection, thereby improving the use efficiency of the device.
