[0002] Air-cushion machines are widely used in industries such as food, medicine, electronics, chemical industry, glass, ceramics, etc., especially in occasions that require high cleanliness, low pollution, and precise control. They not only improve the conveying efficiency of materials, but also reduce the risk of material breakage and pollution, and lower production costs and maintenance expenses.

[0003] The principle of the dust cleaning device is that when the air-cushion machine starts to operate, the dust cleaning device is started accordingly. The dust collection system first collects and processes the dust and impurities on the conveyor belt through the dust suction nozzle. At the same time, the dust scraping mechanism scrapes off the stubborn dust and impurities attached to the conveyor belt under the drive of the drive motor.

[0004] The existing dust cleaning device cannot effectively remove the dust and materials on the conveyor belt. These residues will continue to accumulate on the conveyor belt, increasing the weight of the conveyor belt. The remaining dust and materials may exacerbate the friction between the conveyor belt and the air cushion layer, resulting in increased equipment wear and shortened equipment service life. Therefore, a dust cleaning device for an air-cushion machine is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology, that is, the existing dust cleaning device cannot effectively remove the dust and materials on the conveyor belt. These residues will continue to accumulate on the conveyor belt, increasing the weight of the conveyor belt.

A driving roller 8 is rotatably arranged inside the support seat 6 and fixedly installed on the driving shaft 7. An air cushion conveyor belt 9 is sleeved on the roller surface of the driving roller 8. The middle section of the upper part of the air cushion conveyor belt 9 is located inside the upper part of the air box 5, and the middle section of the lower part is located inside the bottom of the air box 5. A roller brush 12 is arranged between the support plates 11. Both ends of the roller brush 12 are rotatably installed inside the support plates 11 through bearings, and the roller brush 12 is arranged below the outer side of the driving roller 8. During operation, when using the air cushion machine to transport materials, the driving motor 4 is started to drive the driving shaft 7 to rotate.

The transmission wheel 10 drives the roller brush 12 to rotate inside the support plates 11 through the rotating wheel 13 and the belt 14. At the same time, by pumping air into the air box 5, an air flow layer is formed between the air box 5 and the middle section of the upper part of the air cushion conveyor belt 9, so that the air cushion conveyor belt 9 is lifted. The driving roller 8 drives the air cushion conveyor belt 9 to rotate. Materials are put into the sealed box body 1 through the feed hopper 2, and the materials fall onto the upper part of the air cushion conveyor belt 9 for transportation. During the transportation of the materials, dust is generated, and the air mixed with dust inside the sealed box body 1 is extracted through the dust suction pipe 3 and then pumped into the dust removal device for dust removal. At the same time, the materials are transported to the discharge port for discharging through transportation. After discharging, the air cushion conveyor belt 9 continues to move between the roller brush 12 and the driving roller 8, and the rotating roller brush 12 cleans it.

[0023] One end of the driving shaft 7 penetrates through the support seat 6 and is fixedly installed with a transmission wheel 10. One end of the roller brush 12 penetrates through the support seat 6 and is fixedly installed with a rotating wheel 13.

[0028] Working principle: When using the air-cushion machine for material transportation, the driving motor 4 is started to drive the driving shaft 7 to rotate. The driving shaft 7 drives the driving roller 8 to rotate. At the same time, the driving shaft 7 drives the transmission wheel 10 to rotate. The transmission wheel 10 drives the roller brush 12 to rotate in the support plate 11 through the rotating wheel 13 and the belt 14. At the same time, air is pumped into the air box 5 to form an air flow layer between the air box 5 and the middle section of the air-cushion conveyor belt 9, so as to lift the air-cushion conveyor belt 9. The driving roller 8 drives the air-cushion conveyor belt 9 to rotate. Materials are put into the closed box 1 through the feeding hopper 2. The materials fall to the upper part of the air-cushion conveyor belt 9 for transportation. Dust is generated during the material transportation process. The air mixed with dust inside the closed box 1 is extracted through the dust suction pipe 3 and then pumped into the dust removal device for dust removal. At the same time, the materials are transported and moved to the discharge port for discharging. After discharging, the air-cushion conveyor belt 9 continues to move to between the roller brush 12 and the driving roller 8, and the rotating roller brush 12 cleans it. After the roller brush 12 clears the dust on the air-cushion conveyor belt 9, the dust spills into the air. The induced draft fan 16 is started. The operation of the induced draft fan 16 forms a negative pressure in the ash hopper 15, sucking the dust cleaned by the roller brush 12 into the ash hopper 15, and then blowing it into the gauze bag 17. It is filtered through the gauze bag 17, and finally the clean air is discharged.
