[0026] like Figure 1-4 As shown, the present invention proposes a rice surface dust cleaning device, including symmetrically distributed side plates 6. A drive wheel 22 and a driven wheel 23 are rotatably connected to opposite ends of the symmetrically distributed side plates 6. A cleaning conveyor belt 1 is fitted onto the outer end faces of the drive wheel 22 and the driven wheel 23. A drive motor 7 is provided on the outer end face of one side plate 6. The output shaft of the drive motor 7 passes through the side plate 6 connected to it and is coaxially connected to the drive wheel 22. A water spraying assembly is provided above the cleaning conveyor belt 1. Support assemblies are provided on the opposite sides of both side plates 6. The two support assemblies are connected to a collection frame 11 via multiple second fixing rings 9. The bottom of the collection frame 11 is connected to a water outlet assembly via a water outlet hopper 14. A scraping mechanism is provided on the left end of the opposite side of both side plates 6. The distance between the scraping end of the scraping mechanism and the outer end face of the cleaning conveyor belt 1 is 1mm to 2mm.

[0027] In this invention, the drive motor 7 is started, which drives the drive wheel 22 to rotate. The drive wheel 22 can drive the driven wheel 23 to rotate through the cleaning conveyor belt 1. At this time, the rice to be cleaned is evenly spread on the cleaning conveyor belt 1. The spread rice will be moved by the moving cleaning conveyor belt 1. Then, the water spraying component sprays the rice on the cleaning conveyor belt 1 to remove the dust. The water and dust removed will fall into the collection frame 11 and the water outlet 14 through the openings on the cleaning conveyor belt 1. When there is too much water in the collection frame 11 and the water outlet 14, the water can be drained through the water outlet component. When the cleaning conveyor belt 1 transports the cleaned rice to the designated place, the scraping mechanism can remove the rice attached to the outer end surface of the cleaning conveyor belt 1.

[0028] In an optional embodiment, the water spray assembly includes a water pump 17, a connecting pipe 3, and a spray head 2. The water pump 17 is located on the outer end face of one side plate 6. One end of the connecting pipe 3 is connected to the water outlet of the water pump 17, and the other end of the spray head 2 is connected to the spray head 2. The spray head 2 is located above the cleaning conveyor belt 1 with its water outlet facing downward.

[0029] It should be noted that the water inlet of the fixing clamp 10 is connected to an external water pipe. When the water pump 17 is started, water can be pumped into the external water pipe and delivered to the connecting pipe 3. Then, the water is discharged through the spray head 2, thereby cleaning the dust off the rice.

[0030] In an optional embodiment, it further includes a first fixing ring 4, a support frame 5, and fixing clamps 10. The first fixing ring 4 is sleeved on the outer end face of the connecting pipe 3. The outer end face of the first fixing ring 4 is connected to the edge of the upper end face of one side plate 6 through the support frame 5. Multiple fixing clamps 10 are sleeved on the outer end face of the water pump 17, and the multiple fixing clamps 10 are fixed to the outer end face of the side plate 6 connected to the water pump 17.

[0031] It should be noted that the first fixing ring 4 fixed on the support frame 5 can support and fix the connecting pipe 3, ensuring the stability of the connecting pipe 3 during installation. In addition, the multiple fixing clamps 10 ensure the stability of the water pump 17 during fixing.

[0032] In an optional embodiment, the support assembly includes a support plate 13 and support rods 12. The two side plates 6, which are far apart from each other, are respectively connected to the support plate 13. Multiple support rods 12 are spaced apart at the bottom of the support plate 13. Second fixing rings 9 are sleeved on the outer end face of the support rods 12. The outer end face of the collection frame 11 is connected to multiple second fixing rings 9.

[0033] It should be noted that the multiple support rods 12 at the bottom of the support plate 13 can provide stable support for the support plate 13, thereby providing stable support for the side plate 6.

[0034] In an optional embodiment, the water outlet assembly includes a water outlet pipe 16 and a valve 15. The water outlet pipe 16 is located at the water outlet at the bottom of the water outlet hopper 14, and the valve 15 is sleeved on the outer end face of the water outlet pipe 16.

[0035] It should be noted that when valve 15 is opened, the water inside the collection box 11 and the water outlet 14 can flow out through the water outlet pipe 16.

[0036] In an optional embodiment, the scraping mechanism includes a scraper plate 8, a mounting frame 18, fixing bolts 19, and a vibration assembly. The vibration assembly is located between the two side plates 6. The mounting frame 18 is located on the vibration end of the vibration assembly. The scraper plate 8 is located in the mounting groove on the side of the mounting frame 18 away from the vibration assembly. Multiple fixing bolts 19 pass through the mounting frame 18 and extend into the interior of the scraper plate 8. The fixing bolts 19 and the scraper plate 8 are threadedly connected. The vibration assembly includes an electric push rod 20 and a mounting bracket 21. The mounting bracket 21 is located between the two side plates 6. Multiple electric push rods 20 are located on the mounting bracket 21. The vibration ends of the multiple electric push rods 20 are connected to the mounting frame 18.

[0037] It should be noted that the mounting frame 21 can support multiple electric push rods 20. Activating multiple electric push rods 20 can cause the scraper plate 8 to vibrate slightly through the mounting frame 18, ensuring that the gap between the limiting end of the scraper plate 8 and the cleaning conveyor belt 1 is between 1mm and 2mm, which is less than the width of a grain of rice. Furthermore, the electric push rods 20 are miniature electric push rods. When the cleaning conveyor belt 1 moves the rice, the rice adhering to the outer end face of the cleaning conveyor belt 1 can be scraped off by the scraper plate 8. The vibrating scraper plate 8 also facilitates the rice on it to fall off its inclined surface.

[0038] In an optional embodiment, the upper surface of the scraper 8 is smoothly inclined, so that the rice can fall easily when it is scraped down by the scraper 8.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
