The toothed ring 503 is made of stainless steel to avoid the situation that the toothed ring 503 rusts during long-term use, and a cleaning rod 504 fixedly arranged inside the toothed ring 503. When the toothed ring 503 rotates, the cleaning rod 504 can be driven to rotate. The cleaning rod 504 is in contact with the inner wall of the feeding frame 3. When the cleaning rod 504 rotates, the material on the inner wall of the feeding frame 3 can be scraped and cleaned.

[0032] Embodiment Two

[0033] Please refer to Figures 1-5 , the cleaning part 5 also has a driving motor 501 fixedly arranged above the mounting block 402. The driving motor 501 is connected to an external power supply and is fixed above the mounting block 402 by multiple groups of bolts to improve the stability of the overall structure, and a transmission gear 502 fixedly arranged above the driving motor 501. By starting the driving motor 501, the transmission gear 502 can be driven to rotate. The transmission gear 502 is meshed with the toothed ring 503.

By providing two groups of cleaning rods 504, the inner wall of the feeding frame 3 can be cleaned more quickly, and the cleaning speed of the feeding frame 3 can be improved.

[0034] Embodiment Three

[0035] Please refer to Figures 1-5 , the protection part 6, which is arranged above the mounting block 402. The protection part 6 has a protection frame 601 fixedly arranged above the mounting block 402. The protection frame 601 is in the shape of a hollow frame, and both the driving motor 501 and the transmission gear 502 are arranged inside the protection frame 601. The protection frame 601 protects the driving motor 501 and the transmission gear 502 to avoid structural damage caused by external collisions. The connecting block 602 fixedly arranged on the outer side of the protection frame 601 is fixed to the outer wall of the protection frame 601 by welding to prevent the connecting block 602 from separating from the protection frame 601. The fixing rod 603 rotatably connected to the inner side of the connecting block 602 and the switch door 604 hinged to the protection frame 601 on the side of the connecting block 602. The switch door 604 can be opened or closed by rotating the fixing rod 603. The operation is simple, which is convenient for the staff to perform regular maintenance on the structure inside the protection frame 601. The outer wall of the protection frame 601 is provided with a heat dissipation port 605, and a dust-proof net is arranged at the heat dissipation port 605. The heat dissipation port 605 is convenient for the driving motor 501 to dissipate heat, and the dust-proof net blocks external dust to prevent dust from entering the protection frame 601. A rubber pad is arranged on one side of the fixing rod 603 where it is located at the switch door 604, and the rubber pad is in contact with the switch door 604. The friction between the rubber pad and the switch door 604 can fix the fixing rod 603, thus ensuring the stability of the switch door 604 after being fixed.

[0036] Working principle: First, when it is necessary to clean the inner wall of the feeding frame 3, start the driving motor 501. The driving motor 501 works to drive the transmission gear 502 to rotate. Since the transmission gear 502 is meshed with the tooth ring 503, the rotation of the transmission gear 502 will drive the tooth ring 503 to perform a circular motion. Since the cleaning rod 504 is fixedly connected to the tooth ring 503 and the cleaning rod 504 is in contact with the inner wall of the feeding frame 3, the circular motion of the cleaning rod 504 can clean the inner wall of the feeding frame 3, reducing the situation of materials adhering to the inner wall of the feeding frame 3 and ensuring the subsequent material input efficiency of the feeding frame 3;

[0037] Secondly, when it is necessary to maintain the structure inside the protection frame 601, manually rotate the fixing rod 603 to separate the rubber pad on one side from the switch door 604, and then pull the switch door 604 to maintain the structure inside the protection frame 601. When it is necessary to fix the switch door 604 after the maintenance is completed, the switch door 604 can be rotated to fit the protection frame 601, and then the fixing rod 603 is rotated in the reverse direction so that the rubber pad on one side fits the switch door 604 to complete the fixing of the switch door 604. The operation is simple, which is convenient for the staff to perform regular maintenance on the structure inside the protection frame 601.
