[0015] The adjusting plate 24 is rotatably mounted in the corresponding bearing of the air classifier 2 via a plate shaft 26. A connecting plate 27 is integrally formed at the outer end of the plate shaft 26 located in the air classifier 2. The electric push rod 25 is rotatably mounted at a corresponding position in the air classifier 2, and a clamping plate 28 is fixedly mounted at the outer end of the output rod of the electric push rod 25. A clamping groove is formed between the clamping plates 28.

The electric push rod 25 controls the rotation of the connecting plate 27 to control the rotation angle of the adjusting plate 24, thereby adjusting the feeding speed.

[0016] like Figure 1 and Figure 2 As shown, in this embodiment, the exhaust pipe 3 includes a ventilation pipe 31 and a wind control component disposed on the ventilation pipe 31 for controlling the wind suction force. One end of the ventilation pipe 31 is connected to the dust removal channel 23, and the other end is connected to the filter bag dust collector 4.

[0017] The air control assembly includes a wind vane 33 and a base plate 32 disposed at the outer end of the ventilation duct 31.

Positioning holes 36 are distributed along the center of the wind shaft at the outer end of the base plate 32. The positioning pin 35 is inserted into the corresponding positioning hole 36 to fix the wind vane 33, thereby adjusting the airflow suction.

[0018] like Figure 2 As shown, in this embodiment, the filter bag dust collector 4 includes a dust collection box 41 and an exhaust fan 42 disposed on the upper end of the dust collection box 41. Several sets of dust collection filter bags 43 are distributed inside the dust collection box 41 to retain impurities inside the dust collection box 41.

[0021] The working principle of this utility model is as follows: Sesame seeds are introduced into the air classifier box 2 from the feed hopper 21. The material control component adjusts the feeding speed of the sesame seeds. The filter bag dust collector 4 draws away the airflow in the air classifier box 2 through the ventilation pipe 31, so that the dust removal channel 23 generates suction, which makes the light impurities in the sesame seeds rise vertically along the dust removal channel 23. It can also draw away the dust raised by vibration in the screening box 5, thereby improving the internal environment of the air classifier box 2 and the dust removal box 41.

[0022] Sesame seeds in the air separator 2 fall onto the first screen plate 51, where large particles of impurities are filtered out. Sesame seeds fall onto the second screen plate 52, where small particles of impurities enter the dust collection hopper. Sesame seeds are discharged from the second discharge hopper 57 on one side, thus achieving the screening of sesame seeds.
