A driving block 231 is fixedly connected to the outer side of the driven rod 23, and the driving block 231 is rotatably connected to the inner side of the rotation groove 221; the position of the driving block 231 can determine whether the threaded barrel 22 can rotate synchronously with the driven rod 23. When the Chinese medicine powdering operation is performed, the driving block 231 will be located on the inner side of the rotation groove 221. At this time, when the driving rod 24 drives the driven rod 23 to rotate, the driving block 231 follows The driven rod 23 can rotate synchronously inside the rotating groove 221. During the rotation process, the driving block 231 will never contact the inner wall of the rotating groove 221. Therefore, the threaded barrel 22 will not rotate inside the threaded groove 13 at this time, and the two cleaning blocks 3 cannot be driven to clean the inside of the crushing bin 1. When it is necessary to clean the inner wall of the crushing bin 1 with a large amount of drug dust adhering to it, the staff first controls the vacuum noise reduction bin 2 to rotate, and waits for the vacuum noise reduction bin 2 and the crushing bin 1 inside the vacuum noise reduction bin 2 to rotate to the inverted position. When the driven rod 23 follows the vacuum noise reduction chamber 2 in an inverted state, under the action of gravity, the driven rod 23 as a whole will slide inside the threaded barrel 22 toward the base 14, and the driving block 231 will slide synchronously with the driven rod 23 and move to the inside of the limiting groove 222. At this time, when the staff drives the driving rod 24 to rotate through the servo motor 25, under the limiting action of the inner wall of the limiting groove 222, the driven rod 23 that rotates with the driving rod 24 can drive the threaded barrel 22 to rotate synchronously. 3, so the threaded barrel 22 drives the two cleaning blocks 3 to rotate and clean the inner side of the crushing bin 1, and gradually moves toward the top of the crushing bin 1, so as to thoroughly clean the inner wall of the crushing bin 1, and the servo motor 25 can accurately drive the driven rod 23 to rotate an integer number of circles through the driving rod 24, so that the driven rod 23 will not be misaligned with the limiting groove 222 every time it stops rotating, so that the driven rod 23 can smoothly slide to the inner side of the limiting groove 222 when inverted, and drive the threaded barrel 22 and the cleaning block 3 to perform cleaning operations.

Sliding blocks 241 are fixedly connected to both sides of the driving rod 24, and a guide groove 232 is provided on the inner side of the driven rod 23, and the driving rod 24 and the sliding block 241 are slidably connected to the inner side of the guide groove 232; when the driving rod 24 rotates, it can drive the driven rod 23 to rotate through the sliding block 241, so as to drive the crushing part 12 to rotate at high speed, and the opening of the guide groove 232 also enables the driven rod 23 to slide vertically on the outer side of the driving rod 24, so that when the threaded barrel 22 rotates on the inner side of the threaded groove 13, the driven rod 23 can follow the threaded barrel 22 on the outer side of the driving rod 24 and move synchronously toward the top of the crushing bin 1, thereby assisting the two cleaning blocks 3 to complete the cleaning operation of the inner wall of the crushing bin 1.

The working principle and use process of the utility model are as follows: when in use, the staff first drives the crushing bin 1 inside the vacuum noise reduction bin 2 to rise upward through the two driving telescopic rods 11. When the top of the crushing bin 1 slides to the inside of the alignment groove 21, the sealing covers arranged on the top of the crushing bin 1 and the vacuum noise reduction bin 2 can be opened in turn, and then the Chinese medicine raw materials that need to be crushed are placed inside the crushing bin 1, and then the crushing bin 1 and the vacuum noise reduction bin 2 are re-sealed with the sealing cover. At this time, the driving telescopic rod 11 can be controlled to drive the crushing bin 1 downward to the inside of the vacuum noise reduction bin 2 again, and the servo motor 25 can be turned on to drive the crushing part 12 to rotate at high speed to grind the Chinese medicine into powder. During the operation, the staff can control the vacuum noise reduction chamber 2 to swing between the two support columns 15 to drive the crushing chamber 1 inside the vacuum noise reduction chamber 2 to swing synchronously, so that the Chinese medicine raw materials inside the crushing chamber 1 can be more fully contacted and crushed with the crushing part 12, thereby improving the crushing efficiency and quality of the Chinese medicine raw materials. After the Chinese medicine inside the crushing chamber 1 is completed with the powdering operation, the staff can connect the collection bag or collection container with the top of the crushing chamber 1, and then gradually rotate the vacuum noise reduction chamber 2 to pour the powder inside the crushing chamber 1 into the collection bag or collection container for collection. After the powder is collected, it is necessary to clean the dust on the inner wall of the crushing chamber 1. When cleaning, the staff first rotates the vacuum noise reduction chamber 2 and the crushing chamber 1 inside the vacuum noise reduction chamber 2 to an inverted state, and the driven rod 23 will be in an inverted state with the vacuum noise reduction chamber 2. Under the action of gravity, the driven rod 23 will slide toward the base 14 from the inner side of the threaded barrel 22 as a whole. At this time, the driving block 231 will slide synchronously with the driven rod 23 and move to the inner side of the limiting groove 222. At this time, when the staff drives the driving rod 24 to rotate through the servo motor 25, under the limiting action of the inner wall of the limiting groove 222, the driven rod 23 that rotates with the driving rod 24 can drive the threaded barrel 22 to rotate synchronously. Since the threaded barrel 22 is threadedly connected to the threaded groove 13, Therefore, the threaded barrel 22 drives the two cleaning blocks 3 to rotate and clean the inner side of the crushing bin 1, while gradually moving toward the top of the crushing bin 1, and thoroughly cleaning the inner wall of the crushing bin 1. Through the setting of the vacuum noise reduction bin 2, when the Chinese medicine powdering operation is carried out, the vacuum environment between the crushing bin 1 and the vacuum noise reduction bin 2 greatly reduces the propagation and diffusion of noise, thereby achieving a more ideal noise reduction effect. In addition, through the cooperation of the threaded barrel 22, the driven rod 23, and the driving rod 24, it is convenient for the staff to clean the drug dust adhered to the inner wall of the crushing bin 1, so that they can quickly carry out the next batch of powdering operations, which helps to improve the work efficiency of the staff.
