[0027] In this embodiment, the positioning block 11 is fixedly installed on one side of the output end of the stirring motor 4, and the connecting frame 9 is fixedly installed on one side of the top end of the stirring rod 7 and the connecting frame 9 is in the shape of "L".
[0028] Specifically, the positioning block 11 can facilitate the connection between the locking rod 802 and the output end of the stirring motor 4, and can also provide a certain lifting and support effect for the connecting frame 9;
[0029] In this embodiment, the connection port 10 is adapted to the connection frame 9, one end of the connection frame 9 is snapped into and passes through the connection port 10, and the bottom of the snapped end of the connection frame 9 is in contact with the top of the positioning block 11.
[0030] Specifically, the connection port 10, combined with the connecting frame 9, facilitates the initial fixation of the stirring rod 7;
[0031] In this embodiment, the fixing block 801 is fixedly installed on the other side of the top of the stirring rod 7, one end of the spring 804 is fixedly installed at the bottom of the empty groove 803, the empty groove 803 is adapted to the locking rod 802, and the bottom end of the locking rod 802 extends out of the empty groove 803 and is fixedly installed at the other end of the spring 804.
[0032] Specifically, the fixing block 801 facilitates the installation of the locking rod 802;

The stirring rod 7 in the solid storage box 1 and the liquid storage box 2 have the same installation structure.
[0036] Specifically, the movement of the locking lever 802 can be controlled by the lever 807;
[0037] In this embodiment, the cavity 14 is larger than the ball 15. The ball 15 is placed inside the cavity 14 and the specific material of the ball 15 is elastic rubber. Several groups of cavities are evenly distributed in the cavity 14. The vibration motor 13 is fixedly installed on one side of the conveying pipe 5 and is electrically connected to the external power supply.
[0038] Specifically, cavity 14 provides sufficient space for the bouncing of ball 15.
[0039] The working principle and usage process of this utility model are as follows: The conveying pipes 5 of the solid storage box 1 and the liquid storage box 2 are fixed and connected to the dosing box. The conveying pipe 5 can convey solid medicine and liquid medicine into the dosing box. Before the flow meter 6 is installed, different models of flow meters 6 can be selected according to the medicine. Then, the flow meter 6 can realize the precise control of the dosing amount of solid medicine and liquid medicine by the conveying pipe 5. When the conveying pipe 5 conveys solid medicine, the vibration motor 13 is started by the relevant control switch, which can drive the inner wall of the conveying pipe 5 to vibrate. The ball 15 bounces accordingly. Since the cavity 14 is larger than the ball 15, the cavity 14 can provide sufficient bouncing space for the ball 15. The bouncing of the ball 15 can improve the vibration effect of the inner wall of the conveying pipe 5, thereby preventing the solid medicine from accumulating and blocking in the pipe body and affecting the smoothness of the conveying pipe 5 to convey solid medicine.
[0040] Furthermore, during the storage of solid and liquid medicines in the solid storage tank 1 and liquid storage tank 2, the vertical movement of the stirring rod 7 can be limited and locked by the connecting frame 9 combined with the connecting port 10, and the horizontal movement of the stirring rod 7 can be limited and locked by the locking rod 802 combined with the locking hole 12. This allows the stirring rod 7 to be fixed at the output end of the stirring motor 4. By starting the two sets of stirring motors 4 through the relevant control switch, the stirring rod 7 can be driven to rotate, thereby stirring the solid and liquid medicines. The solid medicine is less likely to clump, and the liquid medicine is less likely to settle. When it is necessary to disassemble the stirring rod 7 later, pull down the pull rod 807 so that the locking rod 802 is completely in the empty slot 803, and at the same time move the stirring rod 7 horizontally to disengage the connecting frame 9 from the connecting port 10, thus completing the disassembly of the stirring rod 7. The above operation can be reversed to complete the installation of the stirring rod 7, which is quite convenient. This structure allows for the individual disassembly of the stirring rod 7 after installation, which facilitates the individual cleaning and replacement of the stirring rod 7 later.
