Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 4This utility model provides an embodiment comprising: a roller 1, providing a placement area for macadamia nuts during washing; the roller 1 is the main body of the device for stability; multiple holes are provided on the outside of the roller 1 to facilitate water flow; a conveyor belt 2 is fixedly connected to the inner wall of the roller 1, causing the macadamia nuts to tumble and move forward as they roll within the roller 1; an outer ring 3 is fixedly connected to the outer wall of the roller 1, causing the roller 1 to rotate under the drive of a gear 20; a discharge plate 7 contacts the front end of the roller 1, guiding the macadamia nuts as they are discharged from the front end of the roller 1, ensuring they are concentrated and do not scatter; a water tank 4 is fixedly connected to the lower end of the discharge plate 7, providing stability by fixing the discharge plate 7 above the water tank 4; the water tank 4 provides stability to the entire device; and a feeding plate 8 contacts the rear end of the roller 1, allowing the macadamia nuts to pass through... The feed plate 8 is centrally conveyed into the drum 1. The lower end of the feed plate 8 is fixedly connected to the water tank 4, providing stability by fixing the feed plate 8 at the upper end of the water tank 4. The upper end of the water pump 16 is fixedly connected to the water supply pipe 11, allowing the water pumped from the water pump 16 to flow into the spray pipe assembly 5 and be sprayed out. The rear end of the spray pipe assembly 5 is fixedly connected to the water supply pipe 11 for stability. The upper end of the water supply pipe 11 is fixedly connected to the spray pipe assembly 5, which is equipped with multiple spray nozzles. This allows the macadamia nuts to be rinsed at a specific angle while tumbling, enhancing the tumbling effect and improving the cleaning effect. The front end of the spray pipe assembly 5 is fixedly connected to the support column 9, which provides a fixing effect for the front end of the spray pipe assembly 5. The bottom end of the support column 9 is fixedly connected to the bottom end of the inner wall of the water tank 4, ensuring stability between the water tank 4 and the spray pipe assembly 5.

[0032] Reference Figure 2 , Figure 3A water tank 15 is fixedly connected to the bottom of the inner wall of the water tank 4, keeping the water tank 15 in one area so that it will not change position after water is poured into the water tank 4, providing a stable fixing effect. A water pump 16 is fixedly connected to the upper end of the water tank 15. The water pump 16, which is existing technology, will transport the water passing through the water tank 15 to the water supply pipe 11. A water filtration mechanism is provided at the front end of the water tank 15. The water filtration mechanism includes a water filter box 14. The rear end of the water filter box 14 is fixedly connected to the water tank 15. The water filter box 14 will filter out water containing impurities. The filtered water is sent to the water tank 15 through the filter screen 19. The bottom of the filter tank 14 is fixedly connected to the bottom of the inner wall of the water tank 4, providing a stable fixation. A shrink bag 13 is fixedly connected to the upper end of the filter tank 14, allowing the primary screening box 10 on the shrink bag 13 to extend and retract freely. When the water level changes, the primary screening box 10 will also change position. The primary screening box 10 is fixedly connected to the upper end of the shrink bag 13 and has holes to collect larger impurities without clogging. The water flows through the inlet of the filter tank 14. Float plates 12 are fixedly connected to both sides of the primary screening tank 10, ensuring the inlet of the primary screening tank 10 is always parallel to the water surface. This allows impurities floating on the water surface to enter the primary screening tank 10 with the water flow. Screening blades 17 are rotatably connected to the inner wall of the filter tank 14. Water flows in from the top of the filter tank 14 and out from the rear end into the intermediate water tank 15. The water flow inside the filter tank 14 pushes the screening blades 17 to rotate, carrying away impurities adhering to the filter screen 19. Filter screens 19 are provided on the inner wall of the filter tank 14. 9. Fine impurities are filtered out and do not flow into the water tank 15. The outer wall of the sieve leaf 17 contacts the inner surface of the filter screen 19, so that the impurities on the filter screen 19 are carried away by the sieve leaf 17 and sent to the sludge storage plate 18. The bottom of the water tank 14 has an opening, and the sludge storage plate 18 is inserted into the inner wall of the opening, so that the impurities carried away by the sieve leaf 17 are stored in the sludge storage plate 18. The bottom of the sludge storage plate 18 is a filter screen, so that the impurities are separated from the water when the sludge storage plate 18 is removed. The side of the sludge storage plate 18 is provided with small protrusions to fix the sludge storage plate 18 in the water tank 15.

[0033] Reference Figure 1 , Figure 4A support rod 6 is fixedly connected to the bottom of the inner wall of the pool 4, providing support and stability for the outer ring 3. A gear 20 is rotatably connected to the inner wall of the support rod 6, and a locking tooth is fixedly connected to the inner wall of the outer ring 3. The outer wall of the gear 20 meshes with the outer wall of the locking tooth, causing the locking tooth of the outer ring 3 to drive the roller 1 to rotate through meshing with the gear 20. This meshing makes the connection between the outer ring 3 and the gear 20 more stable. A motor 21 is fixedly connected to the outer wall of the support rod 6, providing stability for the motor 21. The output end of the motor 21 is fixedly connected to the outer wall of the gear 20, providing power for the rotation of the gear 20.

[0034] Working principle: To clean a large number of macadamia nuts, they need to be fed into the equipment from the feeding plate 8. The macadamia nuts will enter the inside of the drum 1 from the feeding plate 8. Driven by the motor 21, the gear 20 will rotate, which will drive the drum 1 to rotate. The conveyor belt 2 inside the drum 1 will make the macadamia nuts inside tumble. The side water spray pipe group 5 will spray water from the side to rinse the macadamia nuts and increase the degree of tumbling to ensure a more thorough cleaning. The macadamia nuts conveyed to the front end will be sent out through the discharge plate 7 to complete the cleaning work.

[0035] During the cleaning process, a large amount of impurities are washed away. The water pump 16 returns the water to the pool 4 and then sends it back to the spray pipe assembly 5 to rinse the macadamia nuts. The water needs to be filtered to prevent impurities from clogging the pump 16 and the spray pipe assembly 5. The water that has rinsed the macadamia nuts flows into the pool 4, and the impurities also flow with the water flow into the water tank 15. First, the impurities flow into the primary screening box 10. Larger impurities that float on the surface are left in the primary screening box 10 to prevent them from clogging the inlet to the filter tank 14. Some smaller impurities enter the interior of the filter tank 14 after passing through, and these impurities are filtered out by the filter tank. The filter screen 19 between the filter screen 14 and the water tank 15 intercepts the water flow, which drives the screen leaf 17 to rotate. The screen leaf 17 carries away the impurities deposited on the filter screen 19 and sends them to the sludge plate 18 to prevent the impurities from clogging the filter screen 19. This prevents these small impurities from clogging the nozzles of the water spray pipe assembly 5 and damaging the pump 16. The water that passes through the filter screen 19 is pumped back to the water spray pipe assembly 5 by the pump 16 for recycling. The primary screen box 10 can be opened from the connection between the float plate 12 and the primary screen box 10 to remove impurities. The sludge plate 18 can be pulled out from the bottom of the filter tank 14 to remove the small impurities filtered by the filter screen 19.
