The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be construed as a limitation on the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a belt cleaning device, including a bottom plate 1, and support plates 2 are fixedly installed at the four corners of the upper end surface of the bottom plate 1. Drive rollers 4 are rotatably installed on two corresponding support plates 2 at the front and back.

[0024] A motor 3 is fixedly installed on the side wall of the support plate 2, and the output shaft of the motor 3 is fixedly connected to the drive roller 4.

[0025] A belt 5 is sleeved and drivingly connected outside the two drive rollers 4. Brush rods 7 are rotatably installed on two corresponding support plates 2 at the front and back. The brush rods 7 are in contact with the surface of the belt 5.

[0026] A linkage assembly is provided between the brush rod 7 and the drive roller 4.

[0027] The linkage assembly includes a first gear 6 and a second gear 8. The first gear 6 is fixedly installed at one end of the drive roller 4 close to the brush rod 7. The second gear 8 is fixedly installed at one end of the brush rod 7, and the first gear 6 and the second gear 8 are meshingly connected.

[0028] U-shaped frames are fixedly installed on two corresponding support plates 2 on the left and right. A moving plate 12 is slidably installed inside the U-shaped frames.

[0029] Two connecting plates 13 are fixedly installed on the moving plate 12.

[0030] To ensure the stability of the connecting plate 13 during movement, a fixed plate is fixedly connected between the two support plates 2 facing away from the U-shaped frame, and one end of each of the two connecting plates 13 facing away from the moving plate 12 is slidably installed on the fixed plate in a limited manner.

[0031] Scrapers 14 are fixedly connected to the opposite surfaces of the two connecting plates 13. The belt 5 passes between the two scrapers 14. A drive assembly is provided on the moving plate 12.

[0032] The driving component includes a ball screw pair, a first bevel gear 9, and a second bevel gear 11. The ball screw pair includes a reciprocating screw rod 10 and a ball nut. The reciprocating screw rod 10 is rotatably installed in the U-shaped frame, and the ball nut is fixedly connected to the moving plate 12. The ball nut is in mating connection with the reciprocating screw rod 10.

[0033] The second bevel gear 11 is fixedly installed at one end of the reciprocating screw rod 10, and the first bevel gear 9 is fixedly installed at one end of the transmission roller 4. The first bevel gear 9 is in meshing connection with the second bevel gear 11.

[0034] To facilitate the collection of waste residue, a collection box 16 is fixedly installed on the upper end surface of the bottom plate 1, and a guide plate 15 is fixedly connected to the upper end of the collection box 16. The guide plate 15 is a cone with the tip facing downwards.

[0035] Working principle:

[0036] During use, the motor 3 is started, and the output shaft of the motor 3 rotates to drive the transmission roller 4 to rotate. The rotation of the transmission roller 4 drives the rotation of one transmission roller 4 through the belt 5, so that the two transmission rollers 4 rotate synchronously.

[0037] The rotation of the transmission roller 4 drives the first bevel gear 9 to rotate, which in turn drives the second bevel gear 11 to rotate. The rotation of the second bevel gear 11 drives the reciprocating screw rod 10 to rotate, which in turn drives the moving plate 12 to move on the reciprocating screw rod 10, which in turn drives the connecting plate 13 to move. The movement of the connecting plate 13 drives the scraper 14 to move. At the beginning, the moving direction of the scraper 14 is the same as the movement direction of the belt 5. When the scraper 14 moves a certain distance, due to the action of the reciprocating screw rod 10, the moving direction of the scraper 14 changes and is opposite to the movement direction of the belt 5, scraping off the waste residue on the surface of the belt 5.

[0038] The rotation of the other transmission roller 4 drives the first gear 6 to rotate, which in turn drives the second gear 8 to rotate. The rotation of the second gear 8 drives the brush rod 7 to rotate to clean the surface of the belt 5. The brush rod 7 and the scraper 14 actively clean the waste residue on the belt, thereby improving the cleaning efficiency.

[0039] The waste residue swept or scraped off falls into the collection box 16 through the guide plate 15.

[0040] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
