One side of the two support frames 5 is fixed with a first housing 4 by bolts. The circumferential outer wall of the first housing 4 is slidably connected with a second housing 6. The circumferential inner wall of the second housing 6 is fixed with a sieve plate 20 by bolts. The circumferential outer wall of the second housing 6 is fixed with a plurality of first fixing plates 8 by bolts.

At the same time, the raw materials in the material box 2 will enter the top of the sieve plate 20 along the connecting pipe 12. Continue to rotate the pushing mechanism. Due to the pulling force of the first tension spring 10, the second housing 6 is reset, thus realizing the rapid addition of raw materials into the grinding device. The operation is simple, the feeding is convenient, and there is no need to stop the grinding device.

[0025] Among them, the pushing mechanism includes a first fixing frame 16, which is fixed to the circumferential outer wall of the material box 2 by bolts. A reduction motor is fixed to the inner wall of one side of the first fixing frame 16 by bolts, and the output shaft of the reduction motor passes through the first fixing frame 16 and is fixed to a push block 13 by bolts.

A fixing mechanism for limiting the top plate 3 is arranged on one side of the top plate 3. When the servo motor is started, the output shaft of the servo motor drives the first grinding disc 25 to rotate, and at the same time the first grinding disc 25 drives the plurality of second grinding discs 29 to rotate. At the same time, the toothed ring 28 meshes with the gear 26, causing the second grinding disc 29 to rotate self - sufficiently, thus realizing the grinding of the raw materials.

[0027] Among them, the fixing mechanism includes two sliding grooves 22, both of which are opened on the top of the top plate 3. An L - shaped plate 23 is slidably connected in each of the two sliding grooves 22. Two clamping grooves 30 are opened on the circumferential inner wall of the first housing 4, and the clamping grooves 30 are clamped with the L - shaped plate 23. A second tension spring 21 is fixed to one side of each of the two L - shaped plates 23 by bolts, and the other end of the second tension spring 21 is fixed to the second fixing frame 24. At the same time, when the two L - shaped plates 23 are pulled inward, the L - shaped plate 23 is disengaged from the clamping connection with the clamping groove 30, and the top plate 3 is disengaged from the fixation, thus greatly facilitating the disassembly of the grinding mechanism, and further greatly facilitating the maintenance and cleaning of the grinding mechanism.

[0028] Among them, the collection mechanism includes a collection box 7, the collection box 7 is arranged at the bottom of the second housing 6, and an adsorption mechanism for fixing the collection box 7 is provided at the top of the collection box 7, which facilitates the collection of the ground raw materials through the collection box 7.

[0031] The working principle of the present invention: When in use, the servo motor is started, the output shaft of the servo motor drives the first grinding disc 25 to rotate, and at the same time the first grinding disc 25 drives a plurality of second grinding discs 29 to rotate. At the same time, the toothed ring 28 meshes with the gear 26 to make the second grinding disc 29 rotate self - sufficiently. Then, under the pulling force of the first tension spring 10, the first fixing plate 8, the second housing 6, and the leakage plate 20 move upward, so that the raw materials on the top of the leakage plate 20 come into contact with the first grinding disc 25 and the second grinding disc 29, thereby realizing the grinding of the raw materials. At the same time, the ground raw materials will fall into the collection box 7 along the through - holes of the leakage plate 20. When the raw materials in the grinding device are ground, first add the raw materials into the material box 2, and then start the reduction motor. The output shaft of the reduction motor drives the push block 13 to rotate. The inclined surface of the push block 13 pushes the convex block 14, so that the first fixing frame 16, the material box 2, the connecting pipe 12, and the second housing 6 move downward, so that the first housing 4 does not block the outlet of the connecting pipe 12. At the same time, the raw materials in the material box 2 will enter the top of the leakage plate 20 along the connecting pipe 12. Continue to start the reduction motor, the output shaft of the reduction motor drives the push block 13 to continue to rotate, so that the push block 13 is separated from the convex block 14. At the same time, due to the pulling force of the first tension spring 10, the raw materials on the top of the leakage plate 20 come into contact with the first grinding disc 25 and the second grinding disc 29 to grind the raw materials, and so on.

[0032] The technical features of the above - mentioned embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above - mentioned embodiments are described.
