The rectangular frame 3 is provided with the rotating shaft 5 which is arranged through both ends of the rectangular frame 3. In use, the rotating shaft 5 can be fixedly connected with the control motor at one end of the rectangular frame 3 for controlling the rotation of the rotating shaft 5. The rotating shaft 5 is coaxially arranged through the grinding cylinder 4. In specific implementation, the two ends of the grinding cylinder 4 are provided with the rotating sleeve 7 which is sleeved outside the rotating shaft 5. The rotating sleeve 7 is axially slidably connected with the rotating shaft 5, and the rotating sleeve 7 is provided with the sealing rubber sleeve. The middle part of the grinding cylinder 4 is fixedly provided with the one-way necked cylinder 41. The one-way necked cylinder 41 has a double-head conical cylinder structure with the large end outward. In specific implementation, the one-way necked cylinder 41 is made of two coaxially welded conical cylinders. The rotating shaft 5 is fixedly sleeved with the grinding cone platform 51 which is located on both sides of the one-way necked cylinder 41. The taper of the grinding cone platform 51 is the same as the taper of the one-way necked cylinder 41. When the grinding cylinder 4 is axially moved, the gap between the one-way necked cylinder 41 and one of the grinding cone platforms 51 will be reduced, and the gap between the one-way necked cylinder 41 and the other grinding cone platform 51 will be increased. That is, the grinding intensity can be controlled by controlling the sliding of the one-way necked cylinder 41. When the grinding cylinder 4 swings up and down, the material in the grinding cylinder 4 will flow through the one-way necked cylinder 41 by gravity and be ground by the corresponding grinding cone platform 51.
