[0023] There are four positioning holes 401, and each of the four positioning holes 401 is a group of two and is respectively distributed on one side and the other side surface of the reinforcement frame 4. The inner wall of each positioning hole 401 is correspondingly distributed with a connecting bearing 402, and the outer surface of the connecting bearing 402 is fixedly connected to the inner wall of the positioning hole 401.

The outer surface of each transmission shaft 403 is correspondingly distributed with a number of crushing teeth 405, and a number of gathering plates 406 are equidistantly distributed on one side and the other side surface of the inner wall of the reinforcement frame 4.

[0024] The driving assembly includes a driving motor 5, a first sprocket 6 is installed on the outer surface of the transmission shaft 403, a chain 601 is installed on the outer surface of the first sprocket 6, a bracket 602 is installed on one side surface of the bottom shell 2, a transmission rod 603 is installed on the inner wall of the bracket 602, a second sprocket 604 is installed on the outer surface of the transmission rod 603, and the driving motor 5 is installed on the top surface of the processing table 1.

[0025] The driving motor 5 is fixedly connected to one end of its transmission shaft 403, the inner wall of the chain 601 is meshed with the outer surface of the first sprocket 6, the inner wall of the chain 601 is meshed with the outer surface of the second sprocket 604, the transmission rod 603 is movably and rotatably connected to the bracket 602, and one end of the transmission rod 603 is fixedly connected to the inner wall of the second bevel gear 208.

[0026] Usage process: When the anti-graffiti paint raw material crushing device is needed, the drive motor 5 is started, and the raw materials to be crushed are put in from the top of the reinforcement frame 4. When the drive motor 5 is started, the transmission shaft 403 connected to its output end is driven to rotate. At this time, the rotating transmission shaft 403 rotates on the inner wall of the connecting bearing 402, and the outer surface of the transmission shaft 403 is equipped with a transmission gear 404, and the transmission gear 404 and the other transmission gear 404 are meshed with each other. Therefore, when the drive motor 5 drives one transmission shaft 403 and the transmission gear 404 to rotate, the transmission gear 404 will drive the other transmission shaft 403 to rotate, so that the two transmission shafts 403 rotate in the same direction, and the outer surface of the transmission shaft 403 is equipped with a powder Crushing teeth 405, when the raw material falls on the outer surface of the crushing teeth 405, the rotating crushing teeth 405 will contact with the raw material, and the crushing teeth 405 rotating with the transmission shaft 403 will squeeze the raw material, and the raw material will be initially crushed by squeezing. At this time, the crushed raw material will fall on the inner wall of the bottom shell 2 and fall on the top surface of the grinding cone 301, and the outer surface of the transmission shaft 403 is equipped with a first sprocket 6. When the driving motor 5 drives the transmission shaft 403 to rotate, the first sprocket 6 installed on its outer surface will also be driven to rotate through the transmission shaft 403. The outer surface of the first sprocket 6 is equipped with a chain 601. At this time, the rotating first sprocket 6 will drive the chain 601 to move by rotating, and the inner wall of the chain 601 At the same time, they mesh with the outer surface of the second sprocket 604, so the rotating first sprocket 6 will drive the second sprocket 604 to rotate through the chain 601, and the rotating second sprocket 604 will drive the transmission rod 603 to rotate on one side surface of the bracket 602, and one end of the transmission rod 603 is fixedly connected to the inner wall of the stabilizing bearing 206, and a second bevel gear 208 is installed on one side surface of the stabilizing bearing 206, so when the transmission rod 603 rotates, it will drive the second bevel gear 208 to rotate, and the second bevel gear 208 and the first bevel gear 207 are meshed with each other. At this time, the first bevel gear 207 will rotate synchronously with the second bevel gear 208, and the grinding shaft 3 is slidably inserted into the inner wall of the first bevel gear 207 and the stabilizing bearing 206. When the first bevel gear 207 rotates, it drives the grinding shaft 3 to rotate. When the grinding shaft 3 rotates, the top surface of the grinding cone 301 contacts the dropped raw material. At this time, the raw material moves to between the grinding cone 301 and the bottom shell 2 with rolling. Because the grinding cone 301 is in a rotating state at this time, and the outer surface of the grinding cone 301 is installed with a first crushing plate 302, when the grinding cone 301 rotates, it drives a plurality of first crushing plates 302 installed on its outer surface to rotate. At this time, the rotating first crushing plates 302 contact the raw material and push the raw material to move. When the raw material moves, it contacts the second crushing plate 205. Because the second crushing plate 205 is in a stationary state, and the first crushing plate 302 is in a moving state,When the first crushing plate 302 and the second crushing plate 205 come into contact with the raw material, the raw material will be crushed by the first crushing plate 302 and the second crushing plate 205 due to the shear force, thereby achieving secondary crushing of the raw material.

[0027] When the raw material is crushed for the second time, the crushed raw material will fall into the gap between the grinding cone 301 and the bottom shell 2. Because the outer surface of the grinding cone 301 is relatively rough, the grinding cone 301 will crush the raw material during rotation. As the grinding cone 301 rotates, the grinding cone 301 will grind the second crushed raw material, so that the size of the raw material is further reduced. When the volume of the raw material is reduced, the raw material will slide out of the gap between the grinding cone 301 and the bottom, and finally fall out of the discharge port 204, thereby realizing multi-stage crushing of the raw material and reducing the volume of the raw material. When the discharge size of the raw material needs to be adjusted, a wrench is used to rotate the adjusting rod 702, and the outer surface of the adjusting rod 702 is provided with a first thread groove 701, and the outer surface of the adjusting rod 702 The first thread groove 701 and the second thread groove 703 on the inner wall of the positioning frame 7 are meshed with each other, and the top surface of the adjusting rod 702 is movably and rotatably connected to the bottom surface of the grinding cone 301 through the positioning bearing 704. When the adjusting rod 702 rotates, the height of the adjusting rod 702 inside the positioning frame 7 will change due to the rotation of the thread. The adjusting rod 702 with the height change will drive the grinding cone 301 to move up and down through the positioning bearing 704, thereby changing the height of the grinding cone 301 inside the bottom shell 2. When the height of the grinding cone 301 changes, the size of the gap between the grinding cone 301 and the bottom shell 2 will also change with the change in the height of the grinding cone 301, thereby controlling the control and adjustment of the size of the raw material crushing.

[0028] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
