Other storage bins 2 that are not being fed remain in a closed state and are not easily contaminated. Embodiment 2

[0053] On the basis of the first embodiment, it is disclosed that the rotation control mechanism includes a movable block 14, a transmission shaft 15 and a motor 16. The movable block 14 is arranged below the feeding chute 11, and the top of the movable block 14 is designed with an inclined structure. The transmission shaft 15 is arranged in the middle of the movable block 14 to control the rotation of the movable block 14. The motor 16 is connected to the transmission shaft 15 to control the rotation of the transmission shaft 15. A vertical sliding structure is formed between the movable block 14 and the feeding chute 11. When the movable block 14 moves upward, the discharge port 12 is closed. A vertical sliding structure is formed between the movable block 14 and the transmission shaft 15. A first connecting block 17 is fixed on the surface of the transmission shaft 15. The transmission shaft 15 drives the movable block 14 to rotate through the first connecting block 17. A second connecting block 18 is fixed inside the feeding adjustment disc 10. A vertical sliding structure is formed between the second connecting block 18 and the movable block 14. A vertical control mechanism is arranged outside the movable block 14. The vertical control mechanism includes a return spring 19, a sliding fitting ring 20 and a pressing-down mechanism. The return spring 19 is arranged below the movable block 14 to provide an upward thrust for the movable block 14. The sliding fitting ring 20 is fixed above the return spring 19, and the upper surface of the sliding fitting ring 20 is in contact with the lower surface of the movable block 14. The pressing-down mechanism is arranged above the movable block 14 to control the downward movement of the movable block 14;

[0054] When it is necessary to control the rotation of the feeding adjustment disc 10, the motor 16 can be started to drive the transmission shaft 15 to rotate. The transmission shaft 15 drives the movable block 14 to rotate through the first connecting block 17. The movable block 14 drives the feeding adjustment disc 10 to rotate through the second connecting block 18, changing the orientation of the discharge port 12 on the feeding adjustment disc 10. After the feeding is completed, the pressing-down effect provided by the pressing-down mechanism on the movable block 14 can be released. At this time, the return spring 19 will push the movable block 14 upward through the sliding fitting ring 20, causing the movable block 14 to move along the feeding chute 11 to block the discharge port 12, keeping the feeding channel 13 in a closed state. When feeding is required later, the movable block 14 can be controlled to move downward to open the feeding chute 11 and the discharge port 12. Embodiment Three

[0055] Based on Embodiment 2, it is disclosed that the downward pressing mechanism includes a control rod 21, a positioning frame 24 and a driving mechanism. The control rod 21 is rotatably installed above the movable block 14. The positioning frame 24 is fixed inside the guiding cover 7, and a vertical sliding structure is formed between the control rod 21 and the positioning frame 24. The driving mechanism is connected to the control rod 21. A dust suction pipe 22 is connected to the right side of the guiding cover 7. A through port 2201 communicating with the dust suction pipe 22 is provided on the right side of the guiding cover 7. The outer end of the dust suction pipe 22 is connected to a dust suction mechanism 23 to absorb the dust generated by the falling of the product. The driving mechanism includes a connecting groove 25, a pressing block 26, an adsorption plate 27 and a support plate 28. The connecting groove 25 is opened at the upper end of the control rod 21.

The right side of the pressing block 26 is designed with an inclined structure. The adsorption plate 27 is fixed to the right side of the pressing block 26 and the adsorption plate 27 is located on the left side of the through port 2201. The support plate 28 is fixed inside the guiding cover 7. The right side of the pressing block 26 penetrates through the support plate 28 and forms a left-right sliding structure with the support plate 28;

[0056] In the default state, the return spring 19 pushes the movable block 14 upward to block the feeding groove 11. When feeding, it is necessary to start the dust suction mechanism 23, so that it absorbs the dust generated by the falling of the product in the guiding cover 7 through the dust suction pipe 22 and the through port 2201 to avoid dust overflow. During the suction process, the adsorption plate 27 moves to the right under the suction force, driving the pressing block 26 to move. The pressing block 26 will press the connecting groove 25, driving the control rod 21 to move downward, so that the control rod 21 presses the movable block 14 to open the feeding groove 11 and the discharge port 12 to ensure the normal progress of subsequent feeding. After feeding is completed, the dust suction mechanism 23 is turned off, the attraction force received by the adsorption plate 27 is released, the return spring 19 pushes the movable block 14 upward, and the pressing block 26 is pressed and reset by the connecting groove 25.
