[0002] A pharmaceutical particle grinder is a device used to grind pharmaceutical particles into finer powders. This type of equipment is usually used in the pharmaceutical, chemical, food and other industries to meet the process requirements for higher raw material particle size in production. The working principle of a pharmaceutical particle grinder is to use high-speed rotating grinding media, such as grinding balls and grinding rods, to impact, rub and shear pharmaceutical particles, thereby grinding them into fine powders.

[0003] In the process of implementing this application, the inventors found that there are at least the following problems in this technology. Existing pharmaceutical particle grinders are mostly made of materials with good heat dissipation during use, so that the heat generated during the pharmaceutical crushing process can be quickly dissipated. However, during the high-speed operation of the grinder, the grinding knife is in direct contact with the pharmaceutical. After a long period of operation, its temperature will become higher and higher. The heat dissipation effect of the grinder alone is still not good, which can easily affect the efficacy of the pharmaceutical. Therefore, further improvement is needed. Utility Model Content

[0021] In this embodiment, the crushing mechanism includes a hollow shaft 10, which is rotatably installed on the top of the accommodating mechanism. The hollow shaft 10 passes through and extends to the bottom of the accommodating mechanism. The top and bottom of the hollow shaft 10 are fixed and connected with a rotating joint 15. A stirring plate 16 is fixedly installed on the outside of the hollow shaft 10. A crushing blade 17 is fixedly installed on the outside of the hollow shaft 10. L-shaped scrapers 18 are fixedly installed on the opposite sides of the left and right stirring plates 16. A spiral blade 19 is fixedly installed on the outside of the hollow shaft 10 and below the crushing blade 17. A liquid guide tube 4 is embedded in the interior of the stirring plate 16, and the liquid guide tube 4 is connected to the hollow shaft 10.

[0022] It should be noted that the L-shaped scraper 18 includes an L-shaped connecting plate and a silicone scraper to prevent the drug powder from sticking to the wall and being difficult to clean. At the same time, the crushed drug powder can be quickly discharged in cooperation with the spiral blade 19.

[0023] Specifically, when the driving mechanism starts the hollow shaft 10 to rotate, its rotary joint 15 is connected to the external transport pipeline, so that the external water pump sends the coolant into the hollow shaft 10, and then discharges it through the lower rotary joint 15, completing the rapid heat exchange of the stirring plate 16, the crushing blade 17 and the spiral blade 19, thereby avoiding the temperature increase of the drug particles during the crushing process that affects the efficacy and ensures the quality of the drug.

[0024] In this embodiment, the accommodating mechanism includes a grinding bin 1, a discharge hopper 2 is fixedly installed at the bottom of the grinding bin 1, a discharge pipe 3 is connected to the lower right end of the discharge hopper 2, and a feed hopper 5 is connected to the right side of the top of the grinding bin 1. The number of stirring plates 16 is twenty, and four stirring plates 16 are arranged in a group on the outside of the hollow shaft 10. Five groups of stirring plates 16 are evenly arranged from top to bottom. The number of crushing blades 17 is five, and the crushing blades 17 and the stirring plates 16 are staggered. The lower crushing blades 17 and the spiral blades 19 are both located inside the discharge hopper 2.

[0025] Wherein, a solenoid valve is fixedly installed on the outside of the discharge pipe 3.

[0026] It should be noted that the crushing blades 17 and the stirring plates 16 are arranged in a staggered manner so that the drug particles can be stirred during the grinding process, making the grinding more uniform.

[0027] In this embodiment, the driving mechanism includes an L-shaped support plate 6, a fan-shaped reciprocating plate 11 and a movable rod 14.
