Then, the driving unit 7 can be controlled to start through the touch control panel 29, and the conveyor belt 6 starts to work to continuously move the sample frame 11 towards the discharging port 9;

[0022] Embodiment 2

[0023] On the basis of Embodiment 1, combined with the attached Figure 5As shown in the figure, a first hydraulic telescopic rod 15 and a second hydraulic telescopic rod 16 are successively arranged at the top end inside the protection frame 4 from left to right. A cutting mechanism 17 is connected to the bottom end of the first hydraulic telescopic rod 15, and a crushing and mixing mechanism 18 is connected to the bottom end of the second hydraulic telescopic rod 16. The cutting mechanism 17 includes a lower pressing plate 19 connected to the bottom end of the first hydraulic telescopic rod 15. A plurality of cutting blades 20 that can extend into the sample frame 11 are evenly arranged at the bottom end of the lower pressing plate 19. The crushing and mixing mechanism 18 includes a lower pressing frame 21 connected to the bottom end of the second hydraulic telescopic rod 16. The lower pressing frame 21 can extend into the sample frame 11. A crushing rod 22 is rotatably arranged inside the lower pressing frame 21.

[0024] With the above structure, when the conveyor belt 6 drives the sample frame 11 to move to directly below the cutting mechanism 17, the conveyor belt 6 stops conveying. The first hydraulic telescopic rod 15 pushes the lower pressing plate 19 to move downward, so that the cutting blades 20 enter the sample frame 11 to cut the sample. Then the first hydraulic telescopic rod 15 retracts the cutting mechanism 17, and the conveyor belt 6 drives the sample frame 11 to continue moving until it moves to directly below the crushing and mixing mechanism 18. The conveyor belt 6 stops conveying. The second hydraulic telescopic rod 16 pushes the lower pressing frame 21 into the sample frame 11. The water valve on the medicine box 25 is opened. The detection medicine is detected by the flow meter 26 and then is extruded into the sample frame 11 through the medicine delivery hose 27 and the medicine extrusion pipes 24. When the flow meter 26 detects that the taken medicine reaches the set specification, the water valve is closed. Then the motor unit controls the crushing rod 22 to rotate, so that the crushing blades 23 cooperate to crush the sample evenly and mix it evenly with the detection medicine. The second hydraulic telescopic rod 16 retracts the crushing and mixing mechanism 18, and the conveyor belt 6 drives the sample frame 11 to continue moving until it is taken out through the blanking port 9.

[0025] When the present utility model is specifically implemented, first, the sample is placed in the sample frame 11. Then the U-shaped plate 12 is pulled to stretch the return spring 13, so that the U-shaped plate 12 is far away from the clamping plate 10. Then the sample frame 11 is placed on the conveyor belt 6 through the feeding port 8. The U-shaped plate 12 is released to enter the card slot 14 under the cooperation of the return spring 13, completing the rapid installation of the sample frame 11;

[0026] After that, the drive unit 7 can be controlled to start by touching the control panel 29, and the conveyor belt 6 starts to work, moving the sample frame 11 continuously in the direction of the discharge port 9. When the conveyor belt 6 drives the sample frame 11 to move directly below the cutting mechanism 17, the conveyor belt 6 stops conveying. The first hydraulic telescopic rod 15 pushes the lower pressing plate 19 downward, so that the cutting blade 20 enters the sample frame 11 to cut the sample. After that, the first hydraulic telescopic rod 15 retracts the cutting mechanism 17, and the conveyor belt 6 drives the sample frame 11 to continue moving until it moves directly below the crushing and mixing mechanism 18. The conveyor belt 6 stops conveying. The second hydraulic telescopic rod 16 pushes the lower pressing frame 21 into the sample frame 11, opens the water valve on the medicine tank 25. The detection medicine is detected by the flow meter 26 and then extruded into the sample frame 11 through the medicine delivery hose 27 and the medicine extrusion pipe 24. When the flow meter 26 detects that the taken medicine reaches the set specification, the water valve is closed. After that, the motor unit controls the rotation of the crushing rod 22 to make the crushing blade 23 cooperate to crush the sample evenly and mix it evenly with the detection medicine. The second hydraulic telescopic rod 16 retracts the crushing and mixing mechanism 18, and the conveyor belt 6 drives the sample frame 11 to continue moving until it moves to the position of the discharge port 9. Pull the U-shaped plate 12 to make it away from the clamping plate 10, and the U-shaped plate 12 moves out of the card slot 14 on the sample frame 11, and the sample frame 11 is taken out, then the sample with pre-treatment inside can be processed in the next step.
