Through the high-speed rotating crushing knife 7, the crushing operation of the medicine is realized. Then, control the set vibration motor 8 to work. Combined with the coordinated work of the support assembly 11 and the support rod 9, the crushing barrel 1 can be vibrated, so that the vibration is transmitted to the filter screen 4, thus avoiding the phenomenon that the medicine blocks the filter screen 4 during crushing, ensuring the smooth flow of the medicine, improving the subsequent tablet mixing efficiency. After the medicine is crushed, it falls to the bottom of the crushing barrel 1 through the filter screen 4. Open the set discharge valve to make the medicine enter the inside of the mixing barrel 2. Then, add a certain amount of water body into the mixing barrel 2 through the water inlet pipe 17. Then, control the first motor 301 to drive the rotating column 302, the stirring rod 303 and the cross bar 304 to rotate synchronously, so that the medicine and water are fully mixed and stirred, improving the medicine mixing effect. Finally, open the set water outlet valve, collect the mixed medicine, and perform subsequent detection on it.

[0035] When the next medicine needs to be crushed and used, turn the set screw 16 by turning the knob to remove the screw 16, remove the barrel cover 5, the rotating rod 6 and the crushing knife 7 at the bottom. At the same time, separate the support column 20 from the filter screen 4. Remove the filter screen 4 through the handle 19 and clean it, and then clean the crushing barrel 1, providing an interference-free environment for the crushing treatment of different medicines in the future, thus ensuring the purity of the medicine mixing and the accuracy of the tablet detection.
