[0026] Specific application examples of the utility model:

[0027] The grinding head 3 is arranged at the end of the rotary rod 2, and the grinding head 3 extending into the grinding tube 1 is driven to rotate by rotating the rotary rod 2 to grind the raw material. A sealing assembly 4 is arranged on the rotary rod 2 near the end of the grinding head 3. The sealing plate 43 in the sealing assembly 4 is mutually abutted and matched with the inner wall of the grinding tube 1 to limit the material in the grinding tube 1. The sealing plate 43 can be detachably arranged on the fixed block 42, which is conducive to the removal and replacement of the sealing plate 43 to adapt to grinding tubes 1 with different inner diameters. The fixed block 42 and the connecting block 41 are rotatably connected to each other to prevent the sealing plate 43 from abutting against the inner wall of the grinding tube 1, thereby hindering the rotation of the rotary rod 2. The baffle 44 arranged on the side of the connecting block 41 near the bottom of the grinding tube 1 covers the fixed block 42, and rotates and slides with the fixed block 42, and covers the gap between the fixed block 42 and the connecting block 41 through the slider 53, which is conducive to preventing the material from entering between the fixed block 42 and the connecting block 41 during grinding. The protrusion 45 arranged on the sealing plate 43 is flush with the baffle 44. It is conducive to reducing the angle and preventing material adhesion.

[0028] The grinding sleeve 31 in the grinding head 3 is arranged outside the base block 32. By replacing the grinding sleeve 31, it is beneficial to make the grinding head 3 adapt to the grinding tube 1 with different inner diameters. The base block 32 is connected to the grinding sleeve 31 through the support plate 33. The inner wall of the grinding sleeve 31 is provided with a slot 34 that matches the support plate 33. The grinding sleeve 31 is fixed by the mutual engagement and matching between the support plate 33 and the slot 34. The screw rod 54 can be made of a bidirectional screw rod 54. The screw rod 54 is rotatably arranged in the base block 32. The screw rod 54 and the slider 53 are mutually threadedly connected. The screw rod 54 rotates to drive the slider 53 to move. The movement of the slider 53 changes the angle between the push rod 52 and the axis of the base block 32, so that the push rod 52 drives the support plate 33 to move. The connecting rod 51 and the base block 32 are mutually slidably connected, and the support plate 33 now moves along a path.
