An electromagnetic brake can be installed at the output end of the second motor 11 for locking and braking when the second motor 11 does not operate. When the filtering and screening cylinder 18 rotates, the feeding port of the filtering and screening cylinder 18 will move to the lower part, so that the materials in the filtering and screening cylinder 18, including foreign objects, will freely fall by gravity;

[0032] Convenient box door 12, symmetrically and rotatably connected to the inner wall of the crushing box 2. The outer wall of the convenient box door 12 is fixedly connected with a door handle 13. By pulling the door handle 13, the convenient box door 12 rotates, so as to open the crushing box 2, so that the inside of the crushing box 2 can be processed when necessary;

The outer wall of the collection box 20 is fixedly connected with a push-pull handle 21. The top wall of the collection box 20 is fixedly connected with a filtering inclined plate 22. A powder collection bin 23 is arranged inside the collection box 20, and a foreign object collection bin 24 is also arranged inside the collection box 20. The top wall of the collection box 20 is detachably connected with a guide frame 26. The powder collection bin 23 collects powders, and the foreign object collection bin 24 collects foreign objects. The two can automatically exchange positions by sliding the collection box 20, which is convenient for classifying and collecting powders and foreign objects.

[0037] Refer to Figure 3 , the cleaning assembly includes a shielding plate 14 fixedly connected to the inner wall of the feeding box 3. The outer walls of the shielding plate 14 and the fixing plate 19 are both fixedly connected with evenly distributed cleaning brushes 15, and the outer wall of the cleaning brushes 15 abuts against the outer wall of the filtering and screening cylinder 18. The surface of the filtering and screening cylinder 18 is cleaned by the cleaning brushes 15.

[0038] Refer to Figure 1and Figure 4 , the inner wall of the guide plate 27 is threadedly connected with a guide rod 28, and the guide rod 28 is located inside the guide frame 26. The collection box 20 can slide out of the support base 1, and the guide rod 28 needs to be taken out so as to be centrally taken out after the powder material.

[0039] Refer to Figure 5 , symmetrically distributed rotating shaft bases 6 are fixedly connected to the outer wall of the crushing box 2. A rotating rod 7 is rotatably connected to the inner wall of the rotating shaft base 6. A driven pulley 8 is fixedly connected to the outer wall of the rotating rod 7. A crushing hammer piece device 25 is also fixedly connected to the outer wall of the rotating rod 7.

[0040] Refer to Figure 1 and Figure 4 , the output end of the first motor 4 is fixedly connected with a driving pulley 5. Belt bodies 9 are arranged on the outer walls of the driving pulley 5 and the driven pulley 8. The driving pulley 5 is driven to rotate by the output end of the first motor 4, and then rotates through the belt body 9, and further drives the driven pulley 8 to rotate.

[0041] Specifically, when the protective device for preventing foreign matter from entering the crusher is working / in use: first, when the material enters through the feed box 3, it will enter the filter screening cylinder 18 along the feed box 3 and the feed port of the filter screening cylinder 18 (not marked in the figure), and at this time, the driving pulley 5 is driven to rotate by the output end of the first motor 4, and then the belt body 9 is rotated, and then the driven pulley 8 is driven to rotate, thereby driving the rotating rod 7 to rotate, thereby driving the crushing hammer 25 to rotate and crush and pulverize the material. After the material is crushed to the passing standard of the filter hole (not marked in the figure) of the filter screening cylinder 18, it will automatically fall and enter the powder in the collection box 20. In the collection bin 23, if the equipment detects foreign matter, the first motor 4 stops running and the second motor 11 starts running. The output end of the second motor 11 drives the driving gear 16 to rotate, and then engages the transmission teeth 29 to drive the filter screening drum 18 to rotate through the rotating circle 17. The output end of the second motor 11 can be installed with an electromagnetic brake for locking the second motor 11 when it is not running. When the filter screening drum 18 rotates, the feed port of the filter screening drum 18 rotates and moves downward, so that the material in the filter screening drum 18, including foreign matter, falls freely under the action of gravity. During the rotation of the filter screening drum 18, the guide plate 27 and the guide rod 28 are driven to rotate, thereby squeezing The guide frame 26 is pressed to drive the collection box 20 to slide in the support base 1. At this time, the foreign matter collection bin 24 replaces the original position of the powder collection bin 23 and is partially blocked by the filter inclined plate 22 to play a guiding role, so that the material and foreign matter can enter the foreign matter collection bin 24. Then the output end of the second motor 11 is flipped, so that the filter screening cylinder 18 is flipped, that is, the guide plate 27 and the guide rod 28 are flipped, thereby driving the guide frame 26 and the collection box 20 to move back to their original positions. At this time, the foreign matter collection bin 24 is located outside the crushing box 2, which is convenient for manual centralized processing of foreign matter. When cleaning is required, the drive gear 16 is driven by the output end of the second motor 11 The filter and screening drum 18 rotates, and then engages the transmission teeth 29 to drive the filter and screening drum 18 to rotate, and cooperates with the cleaning brush 15 to clean the material powder retained on the filter and screening drum 18. The maximum rotation range is a right angle. Due to the range of motion between the guide rod 28 and the guide frame 26, the maximum rotation range of the filter and screening drum 18 is a right angle during the installation of the guide rod 28. The toilet door 12 can be opened through the door handle 13 as needed. The guide rod 28 is threadedly engaged with the guide rod 28 and the guide plate 27 to remove the guide rod 28, thereby releasing the rotation range of the filter and screening drum 18, that is, the rotation range of the filter and screening drum 18 is a right angle, and cleaning can be flexibly performed according to the amount of powder on the filter and screening drum 18.

[0042] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
