[0002] A drug crusher is a device used to crush drugs into powder or granules. It can be used for edible drugs and expired drugs. When destroying expired drugs, the drugs can be crushed to significantly reduce their volume, making it easier to handle and transport them. At the same time, it can ensure that they can no longer be misused or eaten, thereby avoiding possible health risks.

[0003] At present, the existing crushers are usually composed of a crushing chamber, a motor and a crushing block. When in use, the expired drugs to be crushed are placed in the crushing chamber, and the motor drives the crushing block in the crushing chamber to rotate, thereby realizing the crushing operation of the expired drugs. After that, the crushed expired drugs are poured out to realize the destruction operation. However, there are still large particles or lumps in the expired drugs after being processed by the crusher, and it takes a long time to complete the crushing process, which makes the destruction efficiency and effect of expired drugs poor, and it is difficult to meet the destruction needs of expired drugs. Utility Model Content

Expired drugs processed by the existing crushing machine still have large particles or lumps, and it takes a long time to complete the crushing process, which makes the destruction efficiency and effect of expired drugs poor. The utility model is provided with a screen frame and a knocking mechanism. During the crushing process, qualified expired drugs fall into the collection frame through the screen holes of the screen frame, and unqualified drugs continue to be crushed. At the same time, the output end of the driving motor drives the rotating shaft, the supporting shaft and the cam plate to rotate together under the action of the gear set and the pulley set. Since the screen frame and the supporting block are elastically connected by the supporting spring, the screen frame can be reciprocated and the expired drugs on it can be moved during the process of contacting and separating with the screen frame at one end of the cam plate away from the supporting shaft, so that qualified expired drugs can be passed through, thereby preventing the expired drugs from clogging the screen holes, and at the same time, the expired drugs can be fully contacted with the crushing block, thereby improving the crushing efficiency and effect of expired drugs, and then facilitating the rapid destruction of expired drugs, which can meet the demand for the destruction of expired drugs;

A return spring 904 is welded and connected, and a second limit frame 905 forming a snap-fit ​​structure with the limit frame 902 is symmetrically welded at the front end of the collecting frame 10. When the collecting frame 10 is put into the crushing chamber 6, the limit frame 902 is snapped into the second limit frame 905, thereby limiting the collecting frame 10 and preventing it from shifting. The limit frame 902 is pulled upward to separate it from the second limit frame 905. At this time, the collecting frame 10 can be pulled outward to achieve its removal, thereby facilitating the removal of the crushed expired drugs, making the removal process convenient.

[0024] See also Figure 1 , Figure 2 and Figure 4 It can be seen that the crushing chamber 6 is provided with a screen frame 7, and the crushing chamber 6 is provided with a knocking mechanism 8 below the screen frame 7. The knocking mechanism 8 is composed of a support shaft 801, a cam plate 802, a gear set 803, a pulley set 804, a support block 805, a support spring 806, a drive motor 807 and a rotating shaft 808.

The collecting frame 10 is configured as a rectangular structure, and qualified expired drugs in the crushing process can be collected through the collecting frame 10 for centralized processing later.

[0027] The working principle of the utility model is as follows: when the medicine crusher is used for destroying medicines, the expired medicines are placed in the screen frame 7, and the electric push rod 2 is used to control the crushing block 5 to move down into the screen frame 7. At this time, the rotating motor 4 drives the crushing block 5 to rotate, thereby realizing the crushing operation of the expired medicines. In this process, qualified expired medicines fall into the collection frame 10 through the screen holes of the screen frame 7, and unqualified ones continue to be crushed. At the same time, the output end of the driving motor 807 drives the rotating shaft 808, the supporting shaft 801 and the cam under the action of the gear group 803 and the pulley group 804. The wheel plate 802 rotates together, so that in the process of the end of the cam plate 802 away from the support shaft 801 contacting and separating with the screen frame 7, the screen frame 7 can be reciprocated and the expired drugs on it can be moved, so that qualified expired drugs can pass through, thereby preventing expired drugs from clogging the screen holes, and at the same time, the expired drugs can be fully contacted with the crushing block 5, so as to improve the efficiency and effect of crushing expired drugs, and then facilitate the rapid destruction of expired drugs.
