When in use, the cutting piece can be made to work by driving the motor, and the processing assembly 6 is a prior art and will not be described in detail in this article.

[0035] Reference Figure 3-Figure 5 The bottom of the processing bed 2 is fixedly connected with a connecting pipe 7, and the other end of the connecting pipe 7 is fixedly connected with a water tank 8. The interior of the water tank 8 is slidably connected with a filter box 9, and the front side of the filter box 9 is fixedly connected with a mounting plate 10. The interior of the mounting plate 10 is fixedly connected with a compression spring 11, and the other end of the compression spring 11 is fixedly connected with a block 12. A slot 13 is provided in the middle of the water tank 8, and the block 12 and the slot 13 are plugged together. By inserting the filter box 9 and the mounting plate 10 into the water tank 8, when the mounting plate 10 enters, the block 12 will be squeezed and the block 12 will compress the compression spring 11, so that the mounting plate 10 can be completely entered into the water tank 8. When the block 12 moves to a position perpendicular to the slot 13, the block 12 can be bounced into the slot 13 under the action of the compression spring 11, so that the filter box 9 can be quickly installed and fixed.

[0036] Reference Figure 3-Figure 5 The side of the block 12 close to the filter box 9 is set to an arc shape. Under the action of the arc, the block 12 can enter the water tank 8 and can be quickly squeezed by the water tank 8 to move the block 12. The middle part of the mounting plate 10 is rotatably connected with a disassembly component. The inner bottom of the water tank 8 is fixedly connected with a water pump 16. The output end of the water pump 16 is fixedly connected with a water outlet pipe 17. The middle part of the water outlet pipe 17 is fixedly connected to the outside of the processing component 6, and the end of the connecting pipe 7 away from the water pump 16 faces the processing area of ​​the processing component 6.

A pull rope 15 is fixedly connected to the outer side of the rotating rod 14. The other end of the pull rope 15 is fixedly connected to the side of the card block 12 close to the compression spring 11. The pull rope 15 can be reeled in by rotating the rotating rod 14. At this time, the card block 12 can be pulled out of the middle part of the card slot 13 under the action of the other end of the pull rope 15, so that the filter box 9 can be quickly removed, thereby reducing the difficulty of cleaning the filter box 9 and reducing the labor intensity of employees.

[0038] Reference Figure 1-Figure 3A handle is fixedly connected to one end of the rotating rod 14 away from the mounting plate 10, and an anti-skid groove is provided on the outer side of the handle. The rotating rod 14 can be rotated more effectively and comfortably under the action of the handle and the anti-skid groove. Two inclined plates 25 are fixedly connected to the inside of the processing bed 2. A groove is provided at the inner bottom of the processing bed 2, and the groove is arranged between the two inclined plates 25. The working fluid used can quickly flow into the groove and enter the connecting pipe 7 through the inclined plate 25, which can increase the discharge speed of the working fluid. At the same time, it can prevent impurities in the working fluid from entering the connecting pipe 7 and flowing into the water tank 8 along with the working fluid, and can prevent impurities from sticking to the inside of the processing bed 2.

[0039] Reference Figure 3 , Figure 5 and Figure 6 The bottom of the filter box 9 is fixedly connected with a fixed block 18, and the middle part of the filter box 9 is rotatably connected with a convex rod 20. The bottom end of the convex rod 20 is fixedly connected with an impeller 19, and the impeller 19 is rotatably connected to the middle part of the fixed block 18. The outer side of the convex rod 20 is slidably connected with a sleeve shell 21, and the interior of the sleeve shell 21 is fixedly connected with a compression spring 22, and the other end of the compression spring 22 is fixedly connected with a scraper 23. The top of the sleeve shell 21 is fixedly connected with a fastening nut 24, and the fastening nut 24 and the convex rod 20 are threadedly connected. When the working fluid enters the fixed block 18, the impeller 19 can be made. At this time, under the action of the convex rod 20, the sleeve shell 21 can drive the scraper 23 to rotate, and then the impurities filtered at the inner circle position in the middle of the filter box 9 can be swept to the outer circle, which can increase the single use time of the filter box 9, while reducing the frequency of cleaning the filter box 9, which can further reduce the labor intensity of employees.

[0040] Reference Figure 6 The filter box 9 can be cleaned by rotating the sleeve 21 and the sleeve 21 can be removed and replaced by rotating the fastening nut 24, so that the filter box 9 can be fully cleaned. The interior of the sleeve 21 is slidably connected with a partition, which is fixedly connected between the compression spring 22 and the scraper 23. The partition can prevent the scraper 23 from tilting during movement, so that the bottom side of the scraper 23 can contact the filter box 9, and the impurities filtered by the inner circle of the middle part of the filter box 9 can be swept to the outer circle when the scraper 23 rotates, so as to prevent the filter box 9 from being quickly blocked. A plurality of supporting legs are fixedly connected to the bottom of the bottom plate 1, and a connecting rod is fixedly connected to the side close to the plurality of supporting legs. The stability of the bottom plate 1 can be improved by the supporting legs and the connecting rod, so that the overall shaking can be greatly reduced during the operation of the processing bed 2.

[0041] Working principle: When in use, the filter box 9 and the mounting plate 10 are inserted into the water tank 8. When the mounting plate 10 enters, the block 12 is squeezed and the block 12 compresses the compression spring 11, so that the mounting plate 10 can completely enter the water tank 8. When the block 12 moves to a position perpendicular to the slot 13, the block 12 can be ejected into the slot 13 under the action of the compression spring 11, so that the filter box 9 can be quickly installed and fixed. The block 12 and the slot 13 can be separated by rotating the rotating rod 14 and under the action of the pull rope 15, so that the restriction on the mounting plate 10 can be released, and the filter box 9 can be quickly removed;

[0042] Among them, when the working fluid enters the fixed block 18, it will drive the impeller 19 to rotate. At this time, the shell 21 can be rotated under the action of the convex rod 20, and then the scraper 23 can sweep the impurities filtered from the inner circle of the middle part of the filter box 9 to the outer circle, which can delay the speed of clogging of the filter box 9. At the same time, under the action of the compression spring 22, the scraper 23 can be ejected when it is worn, so that the scraper 23 can continue to contact with the filter box 9, and the shell 21 can be removed and replaced by rotating the fastening nut 24.

[0043] 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.
