[0047] It should be noted that the sides of the second synchronous wheels 11 that are close to each other are fixedly connected with drive rods 12, and the drive rods 12 are eccentrically arranged. The two drive rods 12 are respectively used in conjunction with the rotating frame 20 on the same side. During the rotation of the drive rods 12, the rotating frame 20 is pressed down, and the rotating frame 20 rotates downward through the extension rod 22 and the intermediate rod 23. The intermediate rod 23 drives the brush plate 24 to move downward, and then after the drive rod 12 is out of contact with the rotating frame 20, the brush plate 24 is reset under the action of the torsion spring 21, thereby forming a reciprocating motion.

[0048] In the present invention, the scraping mechanism includes a collecting box 9 for collecting impurities, the top of the collecting box 9 is slidably connected to two second sliders 25, the tops of the two second sliders 25 are fixedly connected to the same slag collecting bucket 26, the top of the slag collecting bucket 26 is fixedly connected to a first scraper 27, the top of the first scraper 27 is in contact with the conveyor belt 2, and the first scraper 27 is used to remove materials that are more firmly adhered.

[0049] In particular, one side of the second slider 25 is fixedly connected to a side rod 28, one end of the side rod 28 is rotatably connected to a push rod 17, one end of the push rod 17 is rotatably connected to a drive shaft 29, the two drive shafts 29 are respectively fixed to the two second synchronous wheels 11, the two drive shafts 29 are eccentrically arranged, the drive shaft 29 drives the push rod 17 to reciprocate, the push rod 17 drives the second slider 25 to reciprocate through the side rod 28, the second slider 25 drives the slag bucket 26 and the first scraper 27 to move, thereby increasing the speed of the first scraper 27 and improving the cleaning effect.

[0050] It should be noted that a pull-out box 38 is plugged into one side of the collection box 9, and the pull-out box 38 is used to collect the fallen materials.

[0051] In the present invention, the water replenishment mechanism includes a water replenishment pipe 18 and a mounting seat 33. The water replenishment pipe 18 is fixed on the surface of the bottom plate 6. A plug 30 is inserted at the top of the water replenishment pipe 18. The top of the plug 30 is fixedly connected to a top plate 31. One side of the top plate 31 is fixedly connected to a connecting shaft 32. The mounting seat 33 is fixed to an outer wall of one side of the water tank 7. The top of the mounting seat 33 is rotatably connected to a swing frame 34. A driving groove 36 is provided at one end of the swing frame 34. The connecting shaft 32 is slidably connected to the driving groove 36. Two floating balls 35 are fixedly connected to one end of the swing frame 34 away from the driving groove 36. One side of the water replenishment pipe 18 is fixedly connected to a water outlet pipe 37. The water outlet pipe 37 passes through the water tank 7. When the liquid level drops, the floating ball 35 falls with it, thereby causing one end of the swing frame 34 to rotate downward, and the driving groove 36 at the other end drives the plug 30 to move upward through the connecting shaft 32, so that tap water enters the water tank 7 through the water outlet pipe 37, thereby improving the automation degree of the device.

[0052] In particular, both sides of the frame 1 are fixedly connected with protective plates 4, and the first synchronous wheels 8 and the second synchronous wheels 11 on both sides are respectively located in the protective plates 4 on both sides, and the protective plates 4 increase the safety of the device.

[0053] In the present embodiment, a freezing and scraping structure 39 is fixedly provided on the bottom plate 6. The freezing and scraping structure 39 is arranged on the right side of the water tank 7 and is located directly below the conveyor belt 2. When the conveyor belt 2 transports food with high viscosity and difficult to clean, the conveyor belt 2 cannot be thoroughly cleaned by only relying on the brush roller 10. The freezing and scraping structure 39 can freeze-dry the food with high viscosity and difficult to clean and then scrape it. The freezing and scraping structure 39 includes a fixed groove 40. The top of the fixed groove 40 is open, and the top of the fixed groove 40 is gap-matched with the bottom of the conveyor belt 2. A plurality of electric telescopic rods 41 are fixedly provided on the bottom wall inside the fixed groove 40. The output ends of the electric telescopic rods 41 are fixedly connected to the same bracket 42. A liquid nitrogen storage tank 43 is fixedly provided in the bracket 42. The outlet of the liquid nitrogen storage tank 43 is connected to the bottom of the conveyor belt 2 through a pipe. The pipeline is connected with multiple nozzles 44, and a control valve is arranged in the pipeline. Multiple nozzles 44 are fixedly arranged on the top of the bracket 42. A through hole for the pipeline to pass through is opened on the bracket 42. A second scraper 45 is also arranged on the right side of the bracket 42. The height of the second scraper 45 is higher than the height of the nozzle 44. A strip hole for food residues to fall is opened on the top of the bracket 42 between the nozzle 42 and the second scraper 45. When encountering food residues with high viscosity and difficult to remove, the height of the bracket 42 is adjusted by the electric telescopic rod 41 so that the second scraper 45 is abutted against the conveyor belt 2, and then liquid nitrogen is sprayed out by the multiple nozzles 44 to instantly freeze the difficult-to-remove substances, and then the second scraper 45 is used to thoroughly remove them, and the scraped residues enter the fixed groove 40 from the strip hole for collection, which further improves the cleaning effect of the cleaning and conveying device for food processing. After use, the bracket 42 can be reset by the electric telescopic rod 41. The fixed groove 40 can protect the liquid nitrogen storage tank 43. A door 46 is hinged on the right side of the fixed groove 40, and the residue inside the fixed groove 40 can be cleaned through the door 46.

[0054] When the self-cleaning conveying device for food processing of this embodiment is in use, the motor 3 is started, and the motor 3 drives the conveying roller 5 to rotate, thereby driving the conveyor belt 2 to convey the raw materials. While the conveying roller 5 rotates, the brush roller 10 is driven to rotate through the cooperation of the second synchronous wheel 11, the first synchronous wheel 8 and the synchronous belt, and the conveyor belt 2 is cleaned by the brush roller 10. At the same time, the bottom of the brush roller 10 is immersed in water, and the brush roller 10 is wetted and cleaned by water to maintain the cleaning ability of the brush roller 10. The pressure roller 15 conflicts with the brush roller 10, and the excess cleaning water on the brush roller 10 can be squeezed out to avoid too much water on the brush roller 10 and prevent the conveyor belt 2 from being too wet. Then the threaded rod 16 is rotated, and the threaded rod 16 drives the pressure roller 15 to move through the first slider 14, thereby changing the conflict strength between the pressure roller 15 and the brush roller 10, which is convenient for adjusting the water content of the brush roller 10 and improving the flexibility of use.

[0055] When the second synchronous wheel 11 rotates, the driving rod 12 is also driven to rotate. During the rotation of the driving rod 12, the rotating frame 20 is pressed down, and the rotating frame 20 rotates downward through the extension rod 22 and the intermediate rod 23. The intermediate rod 23 drives the brush plate 24 to move downward. Then, after the driving rod 12 is separated from the contact with the rotating frame 20, the brush plate 24 is reset under the action of the torsion spring 21, and then contacts the brush roller 10, and stirs the cleaning water at the same time, and so on and so forth, thereby cleaning the brush roller 10, thereby improving the cleaning degree and cleaning effect of the brush roller 10;

[0056] While the second synchronous wheel 11 rotates, the push rod 17 is driven to reciprocate through the eccentrically installed drive shaft 29, and the push rod 17 drives the second slider 25 to reciprocate through the side rod 28, and the second slider 25 drives the slag collecting bucket 26 and the first scraper 27 to move, so that the first scraper 27 scrapes off the material firmly adhering to the conveyor belt 2, and the fallen material falls into the pull-out box 38 after being guided by the slag collecting bucket 26, which is convenient for centralized processing;

[0057] When the liquid level in the water tank 7 drops, the float 35 falls accordingly, causing one end of the swing frame 34 to rotate downward, while the driving groove 36 at the other end drives the plug 30 to move upward through the connecting shaft 32, so that tap water enters the water tank 7 through the outlet pipe 37. Conversely, when the water level rises, the plug 30 closes the water supply pipe 18, thereby improving the degree of automation of the device.

[0058] When encountering food residues that are difficult to remove and have high viscosity, the height of the bracket 42 is adjusted by the electric telescopic rod 41 so that the second scraper 45 is in contact with the conveyor belt 2, and then liquid nitrogen is sprayed through multiple nozzles 44 to instantly freeze the difficult-to-remove substances, and then the second scraper 45 is used to thoroughly remove them, thereby further improving the cleaning effect of the cleaning and conveying device for food processing, and the residues inside the fixed groove 40 are regularly cleaned through the box door 46.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
