[0033] It is worth mentioning that by arranging a limited partition 4 and a filter 5 inside the processing barrel 1, the filter 5 can be used to screen and filter large-particle powder in the suspension, and when the stirring motor 302 drives the stirring rod 303 to rotate, the two guide plates 308 can be driven at the same time to stir the powder on the surface of the filter 5, so that the centrifugal force generated by the guide plate 308 can be used to push the powder to the recovery hole 7 on the inner wall of the processing barrel 1, so that the powder can more easily enter the circulation conveying pipe 603.

[0034] Through the above technical scheme, the grinding mechanism 2 includes a grinding basin 201, which is fixedly connected to the top opening of the processing barrel 1. A plurality of strip-shaped discharge holes 202 are provided on the lower surface of the grinding basin 201. A fixed frame 209 is fixedly connected to the upper surface of the grinding basin 201. Two electric telescopic rods 203 are fixedly installed on the upper surface of the fixed frame 209. The telescopic ends of the two electric telescopic rods 203 are fixedly connected to a movable adjustment plate 204.

[0039] Working principle: First, put the medicine into the grinding basin 201, then use the driving motor 205 to drive the rotating rod 206 to rotate, and then drive the grinding block 207 to rotate, and then use the electric telescopic rod 203 to drive the movable adjustment plate 204 to move downward, and then drive the grinding block 207 to rotate inside the grinding basin 201, so as to preliminarily crush the medicine, and at the same time, add appropriate amount of clean water, and then use the clean water to let the ground medicine enter the processing barrel 1 through the discharge hole 202 to form a suspension, and at the same time use the filter 5 to block the large particles in the suspension. , and then use the negative pressure pump 602 to suck air into the negative pressure box 601 to form a negative pressure inside the negative pressure box 601, and then use the circulating conveying pipe 603 to let the suspension above the filter 5 enter the negative pressure box 601 from the recovery hole 7. Since the negative pressure pump 602 works intermittently, after the negative pressure box 601 is filled with the suspension, the negative pressure pump 602 will automatically stop working, and then the negative pressure box 601 will re-input the suspension inside the processing barrel 1 from the liquid inlet hole 8 into the grinding basin 201 for secondary grinding, thereby realizing automatic multiple cycle grinding until extremely fine powder is obtained.
