[0020] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0021] In the present invention, the motor 12 and the telescopic cylinder 9 are connected to the external electric control system through wires. The above devices and connection methods are all existing technologies and will not be described in detail here.

[0022] According to the instruction manual Figure 1-5It can be seen that when the utility model is in use, the grinding balls and the raw materials to be ground are transported to the inner drum 3 through the feed pipe 4. The feed pipe 4 and the rotating shaft 5 connected to the two bottom surfaces of the inner drum 3 are rotatably installed on the side wall of the box body 1 through the bearing. The rotating shaft 5 is driven to rotate by the driving assembly arranged on the box body 1, and then the inner drum 3 is driven to rotate so that the grinding balls crush the raw materials. A cover plate can be arranged on the feed pipe 4 to prevent the raw materials from leaking out of the feed pipe 4 during the grinding process. When the raw materials need to be discharged after grinding for a period of time, the drive assembly arranged in the box body is started. A pair of telescopic cylinders 9 on the inner wall of the body 1 drive a pair of rollers 10 arranged at the telescopic ends thereof to move toward the direction of the outer drum 6. After the pair of rollers 10 abut against the third limiting ring 6-4, they continue to push the third limiting ring 6-4 to move a part of the distance to the right. The third limiting ring 6-4 drives the outer drum 6 and the second limiting ring 6-3 to move a part of the distance to the right, thereby compressing the multiple compression springs 7 arranged between the second limiting ring 6-3 and the first limiting ring 3-3, and at the same time, multiple compression springs 7 arranged on the outer side wall of the inner drum 3 are compressed. The card block 3-2 slides in the multiple slide grooves 6-2, and the card block 3-2 initially located on the right side of the slide groove 6-2 moves to the left side of the slide groove 6-2. When the card block 3-2 abuts against the side wall on the left side of the slide groove 6-2, the multiple first discharge holes 3-1 opened on the inner drum 3 and the multiple second discharge holes 6-1 on the outer drum 6 correspond to each other, and the driving component continues to drive the inner drum 3 and the outer drum 6 to rotate (a pair of rollers 10 also rotate after abutting against the third limit ring 6-4), so that the crushed raw materials are discharged from the multiple first discharge holes 3 -1 and the second discharge hole 6-1 are discharged into the box body 1, and then discharged outwardly through the discharge pipe 2; the utility model drives the inner drum 3 and the outer drum 6 to rotate through a driving component, and a pair of telescopic cylinders 9 drive the outer drum 6 to move on the inner drum 3 to one side of the plurality of compression springs 7, so that the positions of the plurality of first discharge holes 3-1 and the second discharge holes 6-1 correspond to each other, which is convenient for discharging the crushed raw materials outwardly. The raw materials are not discharged through the feed pipe 4 but through the discharge holes, which can prevent the raw materials from accumulating in the inner drum 3, and there is no need to manually clean the accumulated materials.

[0023] There is one possible implementation, when the output end of the motor 12 rotates, it drives the connected second gear 13 to rotate, the second gear 13 drives the meshing connected first gear 11 to rotate, the first gear 11 drives the connected rotating shaft 5 to rotate, the rotating shaft 5 then drives the inner rotating drum 3 to rotate, the inner rotating drum 3 drives the outer rotating drum 6 and other components to rotate.

[0024] There is a possible implementation in which a plurality of telescopic rods 8 are arranged between the first limiting ring 3-3 and the second limiting ring 6-3, a plurality of compression springs 7 are sleeved on the plurality of telescopic rods 8, and the telescopic rods 8 are arranged through the compression springs 7 so that the compression springs 7 do not bend when contracting or extending.

[0025] There is a possible implementation in which a pair of cylinders 14 are horizontally arranged on the inner wall of the box body 1 close to the third limiting ring 6-4, and a pair of telescopic cylinders 9 are arranged in the pair of cylinders 14. The cylinders 14 fix and limit the telescopic cylinders 9 to prevent the telescopic cylinders 9 from loosening.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
