[0020] Please see Figures 1-7In this embodiment of the present invention, a starch grinding device includes a feed pipe 1 and a housing 2. The feed pipe 1 is welded to one side of the top of the housing 2. A grinding body 6 is arranged at the center of the housing 2. Four grinding rollers 7 are evenly distributed on the conical surface of the grinding body 6. A hard brush is provided on the inner wall of the recess on the grinding body 6 that accommodates the grinding rollers 7. The hard brush can clean the rollers 7 when they rotate. The surface of the grinding rollers 7 is provided with clockwise rotating patterns. A conical grinding disc 9 is arranged below the central axis of the grinding body 6. The inner wall of the grinding disc 9 is provided with counterclockwise rotating patterns. The grinding disc 9 is fitted on the outside of the grinding body 6. There is a gap between the conical surface of the grinding body 6 and the inner wall of the grinding disc 9. The grinding roller 7 is exposed in the recess of the grinding body 6 and is in contact with the inner wall of the grinding disc 9. An annular collector 13 is set directly below the grinding disc 9. A height adjustment support plate 15 is set above the bottom plate of the box 2. A motor dust cover 12 is fixed to the side of the height adjustment support plate 15 away from the grinding disc 9 by bolts. The grinding disc drive motor 11 is fixed inside the motor dust cover 12. A drive motor 4 is fixed to the outer side of the box 2 by bolts. The grinding disc drive motor 11 rotates counterclockwise, and the drive motor 4 rotates clockwise. The different directions of the texture of the grinding disc 9 and the grinding roller 7, combined with the rotation direction, can increase the grinding capacity. The output end of the grinding disc drive motor 11 and the bottom end of the grinding disc 9 are both connected to the grinding disc drive pulley 8. The grinding disc 9 and the grinding disc drive pulley 8 of the grinding disc drive motor 4 are connected by a belt. A pad 14 is provided between the height adjustment support plate 15 and the bottom of the grinding body 6. A height adjustment bolt 16 is provided at the bottom of the housing 2, passing through the bottom plate of the housing 2 and connected to the height adjustment support plate 15. The gap between the grinding body 6 and the grinding disc 9 can be adjusted by adjusting the height adjustment bolt 16, which is suitable for various particle size requirements.

[0021] Among them, the output end of the drive motor 4 and the top of the grinding body 6 are both connected to pulleys 8. The grinding body 6 and the pulleys 8 of the drive motor 4 are connected by belts. The top of the housing 2 is equipped with a belt cover 3. The grinding disc drive motor 11 drives the grinding disc 9 to rotate counterclockwise, and the drive motor 4 drives the grinding body 6 to rotate clockwise. The different rotation directions of the grinding body 6 and the grinding disc 9 can increase the grinding capacity and improve efficiency.

[0022] Among them, the bottom of the grinding disc 9 is evenly distributed with multiple straight slot holes, which can ensure that the ground material can fall smoothly into the collector 13 through the straight slot holes when the grinding disc 9 is rotating;

[0023] The bottom outer side of the housing 2 is equipped with four balance support feet 5. The balance support feet 5 can help adjust the horizontal state of the device and extend the service life of the grinding body 6 and the grinding disc 9.

[0024] In operation, starch enters the housing 2 through the feed pipe 1. The drive motor 4 drives the mill body 6 to rotate clockwise via the pulley 8, and the mill disc drive motor 4 drives the mill disc 9 to rotate counterclockwise via the mill disc drive pulley 8. The starch enters between the mill disc 9 and the mill body 6, and is ground by the grinding rollers 7 on the mill body 6 in contact with the mill disc 9. The grinding rollers 7 on the mill body 6 are equipped with hard brushes in their grooves to clean the material adsorbed on the grinding rollers 7. Because the grinding rollers 7 have clockwise grooves and the mill disc 9 has counterclockwise grooves, and the grinding rollers 7 have clockwise grooves, the grinding disc 9... The grinding body 6 rotates clockwise in coordination with the grinding disc 9 rotating counterclockwise, greatly improving grinding efficiency. After grinding to the appropriate level, the ground material enters the bottom of the grinding disc 9. The bottom of the grinding disc 9 has multiple slots through which the material can enter the collector 13 and be discharged from the box 2 for collection. To change the required particle size, the height adjustment bolt 16 at the bottom of the box 2 can be adjusted to move the adjustment support plate up and down, thereby adjusting the gap between the grinding disc 9 and the grinding body 6 to meet various grinding requirements.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
