[0018] The grinding box 10 grinds the calcium carbonate blocks, and the calcium carbonate powder to be re-ground is discharged from the inclined channel 12 to the receiving hopper 21. The receiving hopper 21 is driven by the lifting plate 22 to move upward to the upper feeding port 11. The output end of the telescopic assembly 23 drives the receiving hopper 21 to rotate around the rotating connection between the receiving hopper 21 and the lifting plate 22, so that the calcium carbonate powder in the receiving hopper 21 is re-fed into the device for re-grinding. This cycle continues until the calcium carbonate powder meets the grinding requirements, without manual operation, which is convenient to use.

[0023] Preferably, the rotating shaft of the rotating connection between the lifting plate 22 and the receiving hopper 21 and the push block 31 are arranged on the side close to the grinding box 10. In this scheme, the rotating shaft of the rotating connection between the lifting plate 22 and the receiving hopper 21 is preferably arranged lower than the push block 31. At this time, the telescopic assembly 23 is arranged above the lifting plate 22. When the output end of the telescopic assembly 23 extends, the push block 31 drives the receiving hopper 21 to rotate around the rotating shaft. Of course, the rotating shaft of the rotating connection between the lifting plate 22 and the receiving hopper 21 can also be arranged higher than the push block 31. At this time, the telescopic assembly 23 is arranged below the lifting plate 22.

Correspondingly, the grinding heads 28 can also be gradually reduced from top to bottom. In addition, the driving shaft 17 can be rotationally arranged on the grinding box 10 through a support rod.

[0030] Preferably, the bottom of the grinding box 10 is provided with a plurality of supporting legs 19, and the grinding box 10 can be placed on the bottom plate 24 for use through the supporting legs 19.

[0031] The working principle of the utility model is as follows:

[0032] The calcium carbonate block is fed into the grinding cavity 13 of the grinding box 10 from the upper feeding port 11, the driving mechanism drives the driving shaft 17 and the grinding body 16 to rotate, and the grinding cavity 13 is used to grind the calcium carbonate block, the obtained calcium carbonate powder falls on the screen 15, the calcium carbonate powder meeting the requirements falls along the discharge channel 14 and is collected, and the calcium carbonate powder needing to be ground again is discharged from the inclined channel 12 to the receiving hopper 21; the output end of the motor 25 drives the lead screw 27 to rotate, so that the lifting plate 22 can move upwards along the guide rod 26 at the same time, so as to lift the receiving hopper 21 and the calcium carbonate powder in the receiving hopper 21 to the upper feeding port 11, the output end of the telescopic assembly 23 is extended, the push block 31 pushes the receiving hopper 21 to rotate around the rotating connection between the receiving hopper 21 and the lifting plate 22, as shown in Figures 3 to 4 so that the calcium carbonate powder needing to be ground again in the receiving hopper 21 is fed into the grinding box 10 again to be ground again, and the cycle is continued until the calcium carbonate powder meets the grinding requirements, so that manual operation is not needed and use is convenient.
