The bottom of the grinding rod 11 extends to the inside of the discharge cylinder 5, and a driving component for driving the first rotating shaft 3 and the second rotating shaft 9 to rotate is provided on the top of the base 1 and located on one side of the grinding cylinder 4;

[0025] Specifically, when the driving assembly drives the first rotating shaft 3 and the second rotating shaft 9 to rotate, the first rotating shaft 3 drives the grinding cylinder 4 to rotate, and the second rotating shaft 9 drives the grinding rod 11 at the bottom of the connecting plate 10 to rotate. When the grinding cylinder 4 rotates, it can synchronously drive the discharge cylinder 5 to rotate, so that based on the rotation operation of the discharge cylinder 5 and the grinding rod 11, calcium carbonate can be effectively ground better, and the grinding quality and efficiency are improved. After the grinding work is completed, the electric push rod 16 drives the mounting plate 8 to move upward, and the mounting plate 8 moving upward can drive the grinding rod 11 to move above the discharge cylinder 5.

The overall operation is simple, the grinding work is convenient, efficient, and practical.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The driving assembly includes a rotating rod 12, a first pulley 14, a third rotating shaft 18, a third pulley 17 and a motor 13. The rotating rod 12 is rotatably connected between the top of the base 1 and the top of the fixed frame 2. The first pulley 14 is fixedly connected to the top of the second rotating shaft 9. The third rotating shaft 18 is rotatably connected to the mounting plate 8 and is key-connected to the rotating rod 12. The third pulley 17 is fixedly connected to the outside of the third rotating shaft 18. The motor 13 is fixedly connected to the top of the fixed frame 2.

The top of the rotating rod 12 passes through the inside of the fixed frame 2 and is fixedly connected to the output shaft of the motor 13.

[0027] Specifically, the motor 13 drives the rotating rod 12 to rotate, and the rotating rotating rod 12 drives the third pulley 17 to rotate. Under the rotation action of the first pulley 14, the rotation operation of the first rotating shaft 3 can be realized, so as to better drive the grinding rod 11 to rotate for grinding work, and the third pulley 17 is key-connected to the rotating rod 12 through the third rotating shaft 18, so that when the mounting plate 8 moves up and down, it can drive the third rotating shaft 18 to be slidably connected with the rotating rod 12, which is beneficial to the up and down movement operation of the mounting plate 8.

[0031] Reference Figure 1 and Figure 2 The mounting plate 8 is slidably connected to the outer side of the fixing frame 2 at a side close to the fixing frame 2. Specifically, the mounting plate 8 fitted to the outer side of the fixing frame 2 can ensure its stability, so as to ensure the stability of the rotation of the second rotating shaft 9 and the grinding rod 11.

[0032] The motor 13 and the electric push rod 16 are both electrically connected to external control equipment to facilitate the control of the operating status of the motor 13 and the electric push rod 16 to achieve automated operation of the device.

[0033] Working principle: The motor 13 drives the rotating rod 12 to rotate, and the rotating rotating rod 12 drives the third pulley 17 to rotate. Under the rotation of the first pulley 14, the first rotating shaft 3 can be rotated to better drive the grinding rod 11 to rotate. When the rotating rod 12 rotates, it drives the second pulley 15 to rotate, so as to realize the rotation operation of the first rotating shaft 3. When the first rotating shaft 3 drives the grinding cylinder 4 to rotate, it can synchronously drive the discharge cylinder 5 to rotate. Therefore, based on the rotation operation of the discharge cylinder 5 and the grinding rod 11, calcium carbonate can be effectively ground better, and the grinding quality and efficiency are improved;
