The bottom of the scraper 43 contacts and acts on the first filter screen 32.

[0021] As Figures 2 - 5As shown in the figure, it further includes a housing 5, a reduction gear set 51, a grinding disc 6, a second filter screen 61, a gear ring 7, a transmission gear 8, and a grinding drum 81. The output shaft of the motor 4 rotates through the middle of the first filter screen 32. In the middle of the bottom of the first filter screen 32, a housing 5 is fixedly connected. A reduction gear set 51 is installed inside the housing 5. The upper end of the reduction gear set 51 is the input shaft, and the lower end is the output shaft. The top of the input shaft of the reduction gear set 51 is fixedly connected to the bottom of the output shaft of the motor 4. The bottom of the output shaft of the reduction gear set 51 is fixedly connected to the upper top of the grinding disc 6. The upper part of the grinding disc 6 is in the shape of an inverted frustum. The lower top of the grinding disc 6 is an annular inclined surface that slopes downward outward with the inverted frustum as the center. The lower part inside the grinding disc 6 is in the shape of an inverted frustum, and the outer part of the lower part of the grinding disc 6 is in a ring structure. A second filter screen 61 is fixedly connected between the outer side of the annular inclined surface of the grinding disc 6 and the top of the ring structure. The second filter screen 61 is located inside the first grinding frame 2. The lower part of the grinding disc 6 is rotationally closed with the bottom of the first grinding frame 2. The upper part of the outer side of the ring structure of the grinding disc 6 is fixedly connected with a gear ring 7. The gear ring 7 is located outside the grinding disc 6. Three grinding drums 81 are evenly spaced and rotatably connected to the lower part of the first grinding frame 2. The grinding drums 81 are in the shape of an inverted frustum with an inclined setting. The inclined surfaces on one side where the three grinding drums 81 are close to each other are in contact with the inclined surface of the upper inverted frustum side of the grinding disc 6, and the bottoms of the inclined surfaces on the inverted frustum sides of the three grinding drums 81 are in contact with the annular inclined surface of the lower top of the grinding disc 6. On the side where the grinding drums 81 are far from each other, a transmission gear 8 is fixedly connected. The transmission gear 8 meshes with the gear ring 7.

[0022] As Figure 1 and Figure 2 shown in the figure, it further includes a guiding frame 9. A guiding frame 9 is fixedly connected to the middle of the support frame 1. The guiding frame 9 is located directly below the grinding disc 6. The second filter screen 61 is in communication with the inside of the guiding frame 9.

[0023] As Figure 5 and Figure 6 shown in the figure, it further includes a scraping bar 91. Three scraping bars 91 are fixedly connected to the circumference of the bottom of the inverted frustum of the lower part of the grinding disc 6 at equal intervals. The scraping bars 91 are inclined. The scraping bars 91 are in contact with the inner wall of the guiding frame 9.

[0024] As Figure 1 shown in the figure, it further includes a collection box 10. The collection box 10 is slidably connected to the inner bottom of the support frame 1. The collection box 10 is located directly below the guiding frame 9.

[0025] When the raw materials need to be ground, rotate the cover plate 31 to open it, so that the cover plate 31 is disengaged from the feed inlet of the second grinding frame 3, thereby opening the second grinding frame 3. Then pour an appropriate amount of raw materials to be ground into the second grinding frame 3. Under the action of gravity, the raw materials to be ground fall onto the first filter screen 32. Subsequently, rotate the cover plate 31 in the reverse direction to reset it, so that the cover plate 31 comes into contact with the feed inlet of the second grinding frame 3, thereby closing the second grinding frame 3.

[0026] Then, control the output shaft of the motor 4 to drive the conical connecting block 41 to rotate clockwise. The conical connecting block 41 drives the crushing blade 42 and the scraping plate 43 to rotate clockwise. Through the continuous rotation of the crushing blade 42 in contact with the raw materials on the first filter screen 32, the raw materials can be crushed. At the same time, through the contact between the bottom of the scraping plate 43 and the first filter screen 32, the crushed raw materials on the first filter screen 32 can be scraped, so that the materials that meet the aperture size of the first filter screen 32 fall downward into the first grinding frame 2, and the materials that do not meet the aperture size of the first filter screen 32 continue to move with the scraping plate 43, preventing the first filter screen 32 from being blocked. And through the contact between the inclined surface of the scraping plate 43 and the materials, the materials can be pushed and gathered in a specific direction, facilitating the subsequent crushing. In this way, it is possible to crush and screen at the same time, ensuring the crushing effect while automatically screening, with simple operation, time-saving and labor-saving, and improving work efficiency.

[0027] At the same time, the output shaft of the motor 4 is decelerated by the reduction gear set 51 and will drive the grinding disc 6 to rotate slowly clockwise. The grinding disc 6 drives the second filter screen 61 and the gear ring 7 to rotate clockwise. Through the meshing of the gear ring 7 and the transmission gear 8, three grinding drums 81 will be driven to rotate synchronously. Through the contact between the inclined surfaces on both sides of the grinding drums 81 and the inclined surfaces on both sides of the grinding disc 6 respectively, the materials falling into the first grinding frame 2 can be fully ground. And through the continuous rotation of the grinding disc 6 driving the ground materials to move, the materials in the first grinding frame 2 can be alternately contacted with the three rotating grinding drums 81 in turn for grinding, so that the materials can be quickly and comprehensively ground, ensuring the grinding effect and improving the grinding efficiency. And the continuously rotating second filter screen 61 can screen the ground materials while effectively preventing the materials from blocking the second filter screen 61, automatically screening the materials and reducing subsequent operation steps; Under the action of gravity, the ground qualified materials are guided by the guiding frame 9 and will fall downward into the collecting frame 10 for collection. At the same time, the grinding disc 6 drives the scraping bar 91 to rotate. Through the contact between the scraping bar 91 and the inner wall of the guiding frame 9, the materials on the guiding frame 9 can be scraped off, so that the materials can smoothly fall downward into the collecting frame 10, thereby reducing material residue and improving work efficiency.

[0028] After use, the output shaft of the control motor 4 stops working, causing the conical connecting block 41, the grinding disc 6 and its upper components and the grinding drum 81 to stop working. Then, the collection box 10 is pulled forward to disengage the collection box 10 from the support frame 1. Subsequently, the ground materials can be uniformly collected, which is convenient for operation. After collection, the collection box 10 is placed back on the support frame 1. Then, according to needs, the above steps are repeated to process the next batch of raw materials to be ground, facilitating subsequent normal use.

[0029] As Figure 6 shown, it further includes an anti-slip pad 11, and the bottom of the support frame 1 is fixedly connected with the anti-slip pad 11. The setting of the anti-slip pad 11 can increase the friction between the bottom of the support frame 1 and the ground, thereby improving the safety of use.

[0030] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
