[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1-8 , when the existing grinding device crushes drugs, large-particle drugs enter the device through the feed inlet. However, it is not convenient to dredge the drugs during feeding. When the drugs are blocked in the feed inlet, it will affect the subsequent feeding and the crushing efficiency of the drugs. To solve this technical problem, the following technical content is disclosed in this embodiment. A drug crushing device for treating the spleen and stomach in traditional Chinese medicine internal medicine includes a housing 1. A discharge port 2 is provided on the front side of the housing 1, and a feed hopper 3 is fixedly installed at the upper end of the housing 1. The lower end of the feed hopper 3 extends into the interior of the housing 1. A guide plate 4 is provided at the lower end of the feed hopper 3, and a filter cover 5 is installed in the middle of the lower end of the guide plate 4. A plugging rod 6 is provided at the lower end of the guide plate 4, and the plugging rod 6 is connected to the guide plate 4 through a built-in spring 7. The plugging rod 6 is inserted into the hole on the side of the filter cover 5. A servo motor 8 is fixedly installed in the middle of the upper end of the housing 1, and the output end of the servo motor 8 is fixedly connected to a transmission rod 9. A movable column 10 is fixedly installed at the lower end of the transmission rod 9, and the movable column 10 extends into the interior of the filter cover 5. Crushing convex teeth 13 are fixedly installed on the side of the movable column 10, and a dredging structure 11 is provided on the side of the feed hopper 3. The dredging structure 11 is used to vibrate the feed hopper 3 caused by impact to prevent blockage inside the feed hopper 3. The middle of the guide plate 4 is set as a concave surface, and the guide plate 4 is located directly below the feed hopper 3. The plugging rod 6 and the lower end of the guide plate 4 form an elastic telescopic structure through the built-in spring 7, and the outer wall of the plugging rod 6 fits with the inner wall of the hole on the side of the filter cover 5. A plurality of crushing convex teeth 13 are evenly distributed in the circumferential direction of the movable column 10, and the crushing convex teeth 13 and the movable column 10 are integrally formed. The dredging structure 11 includes a positioning ring 111, a connecting magnet 112, a movable rod 113, and an auxiliary spring 114. The positioning ring 111 is fixed on the transmission rod 9. A movable rod 113 is provided on the side of the positioning ring 111, and the movable rod 113 is connected to the interior of the housing 1 through an auxiliary spring 114. Connecting magnets 112 are fixed at the ends of the positioning ring 111 and the movable rod 113. The connecting magnets 112 are evenly distributed in the circumferential direction of the positioning ring 111, and the connecting magnet 112 on the positioning ring 111 and the connecting magnet 112 at the end of the movable rod 113 have opposite magnetic polarities. The movable rod 113 can slide inside the housing 1, and the end of the movable rod 113 close to the feed hopper 3 fits with the feed hopper 3.

[0031] When the medicine needs to be crushed, the container containing the medicine is placed under the filter cover 5 through the discharge port 2, and then the servo motor 8 is turned on. The turning on of the servo motor 8 can make the transmission rod 9 rotate, and the rotation of the transmission rod 9 can make the movable column 10 rotate synchronously, and the large-particle medicine to be crushed is put into the interior of the device through the feed hopper 3. The medicine can slide into the filter cover 5 through the depression in the middle of the guide plate 4. The medicine in the filter cover 5 can be crushed by the rotation of the movable column 10 and the crushing convex teeth 13. The crushed medicine leaks out into the container through the holes on the filter cover 5, and the rotation of the transmission rod 9 can drive the positioning ring 111 to rotate synchronously. After the positioning ring 111 rotates, the connecting magnetic block 112 on its edge and the connecting magnetic block 112 at the end of the movable rod 113 are connected. When the hopper 11 is in contact with the feed hopper 3, the drug in the feed hopper 3 is cleared and blocked. When the drug is crushed, the plug-in rod 6 is pulled toward the outside of the guide tray 4. After the plug-in rod 6 moves, the inner end of the plug-in rod 6 can be separated from the hole on the side of the filter cover 5, thereby releasing the fixation of the filter cover 5, making it easier for the filter cover 5 to be removed and cleaned after moving downward.

[0032] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. The following technical content is disclosed in this embodiment: a guide structure 12 is installed on the transmission rod 9, and the guide structure 12 is used for the filter cover 5 to reciprocate and impact. The guide structure 12 includes an adjustment power arm 121, a return spring 122, a resistance block 123, a pressure block 124 and a collision rod 125, and the adjustment power arm 121 is installed on the transmission rod 9. The adjustment power arm 121 is connected to the movable column 10 through the return spring 122, and a resistance block 123 is fixed below the end of the adjustment power arm 121. A pressure block 124 is provided below the resistance block 123, and the pressure block 124 is fixed to the upper end of the guide plate 4. The lower end of the adjustment power arm 121 is fixed with a collision rod 125, and the collision rod 125 is installed on the movable column 10. The middle portion of the adjustment power arm 121 can slide on the transmission rod 9, and the collision rod 125 at the lower end of the adjustment power arm 121 can slide on the movable column 10. In the initial state, the lower end of the collision rod 125 is in contact with the filter cover 5. The surfaces of the interference block 123 and the pressure block 124 are both configured as an arc structure, and the pressure blocks 124 are evenly distributed on the upper end of the guide plate 4.

[0033] When the transmission rod 9 rotates, it can cause the adjustment power arm 121 to rotate synchronously. After the adjustment power arm 121 rotates, it can drive the contact block 123 thereon to rotate synchronously. When the contact block 123 contacts the pressing block 124 on the material guiding plate 4 after the adjustment power arm 121 rotates, the pressing block 124 can thus push the contact block 123, enabling the adjustment power arm 121 to move along the upper side of the transmission rod 9. After the adjustment power arm 121 moves, it can drive the collision rod 125 to move synchronously. When the contact block 123 on the adjustment power arm 121 separates from the pressing block 124 on the material guiding plate 4 after the adjustment power arm 121 rotates, the adjustment power arm 121 rebounds under the action of the return spring 122. After the adjustment power arm 121 resets, it can cause the collision rod 125 thereon to reset synchronously and impact the filter cover 5. By using the vibration generated by the impact on the filter cover 5, it is possible to prevent the drug from getting stuck in the holes of the filter cover 5.
