The conveying roller 4 is located on the upper inner side of the grading box 2, and its function is to push the potatoes forward in the grading box 2 to ensure that they can pass the grading process. The baffle 3 is located on both sides of the grading box 2 to guide and limit the movement direction of the potatoes to ensure that they move along the set path. A plurality of output boxes 5 are located on one side of the grading box 2 to receive and contain the sorted potatoes. The partition 6 is used to separate products of different grades.

[0025] Reference Figure 1 , Figure 2 and Figure 4The cleaning component includes a cleaning pipe 9, which is fixedly connected to the inside of the grading box 2, a water pump 14 is fixedly connected to one side of the grading box 2, the cleaning pipe 9 is fixedly connected to the output end of the water pump 14, and a nozzle 10 is fixedly connected to one side of the cleaning pipe 9. The filtering component includes a water storage tank 1, which is fixedly connected to the lower part of the grading box 2, a filter frame 7 is slidably connected to the inside of the water storage tank 1, a filter plate 16 is fixedly connected to the inside of the filter frame 7, a sealing ring 13 is fixedly connected to the outer periphery of the filter frame 7, a sealing groove is opened inside the water storage tank 1, and the sealing ring 13 is snap-connected inside the sealing groove. An input pipe 15 is fixedly connected to the input end of the water pump 14, and the input pipe 15 is fixedly connected to the inside of the water storage tank 1.

[0026] Specifically, the cleaning pipe 9 is located inside the grading box 2 and is used to provide water. The water pump 14 is located on one side of the grading box 2 and is used to deliver water into the cleaning pipe 9. The nozzle 10 is located on one side of the cleaning pipe 9 and is used to spray water onto the potatoes for cleaning. The water storage tank 1 is located at the lower part of the grading box 2 and is used to store water and also serves to stabilize the equipment. The filter frame 7 is located inside the water storage tank 1 and is used to filter impurities in the water. The filter plate 16 is fixed inside the filter frame 7 to further help filter the cleaning liquid. The sealing ring 13 is used to seal the filter frame 7 to prevent water leakage and can also fix the filter frame 7. The input pipe 15 connects the water pump 14 and the water storage tank 1 and is used to deliver water to the grading box 2.

[0027] Reference Figure 1-Figure 3 The support plate 17 and the grading box 2 are provided with a plurality of drainage holes, and the inclined plate 11 is also provided with drainage holes. The output box 5 is abutted against the upper part of the support plate 17, and the partition plate 6 is abutted against the upper part of the support plate 17. A handle is fixedly connected to the outside of the filter frame 7, and the material used for the sealing ring 13 is rubber.

[0028] Specifically, the support plate 17 is fixed inside the water storage tank 1 to support the output box 5, and multiple drainage holes are opened on the upper part and inside the grading box 2 to help drain water. The drainage holes exist on the support plate 17, the inclined plate 11 and other components to drain water and prevent water from accumulating inside the device. The handle is used to facilitate the removal of the filter frame 7, and the rubber material has good sealing performance.

[0029] Working principle: When the equipment is running, potatoes are transported into the grading box 2 through the conveying rollers 4. As the distance between the conveying rollers 4 gradually increases from small to large, potatoes of different sizes fall into different spaces. Then, the potatoes are guided by the inclined plate 1 8 and the inclined plate 2 11 to be sent to the corresponding output box 5, thereby completing the automatic grading of potatoes. During the cleaning process, the water pump 14 draws out the water in the water storage tank 1, sprays it through the nozzle 10, cleans the potatoes, and washes away the dirt on the surface. The dirty water after cleaning flows into the lower part of the grading box 2 through the guidance of the inclined block 12, and is filtered through the filter assembly. In the filter assembly, the sealing ring 13 is engaged inside the sealing groove, dividing the water storage tank 1 into a cleaning area and a sedimentation area. The dirty water after cleaning is filtered by the filter plate 16, leaving the dirt on the filter plate 16, and the clean water flows into the cleaning area of ​​the water storage tank 1 through the channel inside the filter plate 16. When the filter plate 16 needs to be cleaned, the handle is pulled to disengage the sealing ring 13 from the sealing groove, and then the filter plate 16 is pulled out to clean the dirt on the surface. The cleaned filter plate 16 is inserted into the water storage tank 1 again, and the sealing ring 13 and the sealing groove are engaged to restore the normal operation of the filter assembly.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
