A limiting plate 21 is rotatably connected to the side wall of the surrounding frame 9 near the upper end. A connecting bolt 22 penetrates through the side wall of the limiting plate 21 near the lower end, and the connecting bolt 22 is screwed to the positioning frame 6. By loosening the connecting bolt 22, the limiting plate 21 can be rotated and opened, thus facilitating the loading of the placing plate 20 into the inner side of the surrounding frame 9.

[0022] The supporting mechanism includes a supporting plate 8 arranged inside the lower material port 7. A rotating shaft 25 penetrates through the side wall of the supporting plate 8, and the rotating shaft 25 is rotatably connected to the supporting plate 8.

A stop bar 19 is fixedly sleeved at one end of the material pushing plate 18 close to the activity plate 17. The stop bar 19 can limit the material pushing plate 18, thereby being able to limit the extreme position of the leftward movement of the material pushing plate 18. A spring 29 is arranged inside the activity groove 28. One end of the spring 29 is fixedly connected to the inner wall of the activity groove 28, and the other end of the spring 29 is fixedly connected to the activity plate 17. A connecting frame 16 is provided on the side of the activity plate 17 away from the material pushing plate 18. A connecting groove 30 is provided on the side wall of the connecting frame 16. One end of the activity plate 17 away from the material pushing plate 18 is slidably connected to the inside of the connecting groove 30. Two connecting rods 27 are fixedly connected to the end of the activity plate 17 located inside the connecting groove 30. The connecting rods 27 penetrate through the inner wall of the connecting groove 30, and the connecting rods 27 are slidably connected to the connecting frame 16. A pressure contact switch 31 is arranged on the inner wall of the connecting groove 30, and the pressure contact switch 31 is electrically connected to the electromagnetic push rod 26. Since the spring 29 has a supporting force on the material pushing plate 18, when the connecting frame 16 moves leftward, the activity plate 17 will first squeeze and trigger the pressure contact switch 31, so that the electromagnetic push rod 26 is energized and remains in the extended state. The extension of the electromagnetic push rod 26 can cause the supporting plate 8 to rotate upward, and the supporting plate 8 maintains a horizontal state to block the lower material port 7. The connecting frame 16 penetrates through the second vertical plate 15 and is slidably connected to the second vertical plate 15. The connecting frame 16 is fixedly connected to the sliding sleeve 12.

[0024] The material taking mechanism includes a first mounting plate 35 fixedly connected to the inner side of the mounting frame 10. Four material taking cylinders 34 are provided through the upper end of the first mounting plate 35, and the material taking cylinders 34 are fixedly connected to the first mounting plate 35. A negative pressure pump 32 is provided on the inner top wall of the mounting frame 10. The suction end of the negative pressure pump 32 is connected with a ventilation pipe 33, and the ventilation pipe 33 is connected with the material taking cylinders 34. A third electric telescopic rod 38 is mounted on the inner top wall of the mounting frame 10. The telescopic end of the third electric telescopic rod 38 faces downward and is fixedly connected with a second mounting plate 37. Four pressing members are provided at the lower end of the second mounting plate 37. The four pressing members are respectively located inside the four material taking cylinders 34. The pressing member includes a movable rod 36 fixedly connected to the lower end of the second mounting plate 37. The lower end of the movable rod 36 penetrates through the top of the material taking cylinder 34 and extends into the interior of the material taking cylinder 34. A pressing plate 39 is fixed to the lower end of the movable rod 36. The pressing plate 39 is driven to move downward by the movable rod 36, and the drug sensitivity paper 24 is pressed and pasted on the surface of the culture dish by the pressing plate 39.

[0025] When the present invention is in use, the culture dish is placed inside the positioning ring 5. The second electric telescopic rod 14 is started to contract at the first stage, driving the sliding sleeve 12 to slide leftward on the guide rod 13. The connecting frame 16 is driven to move leftward by the sliding sleeve 12. Since the spring 29 has a supporting force on the pushing plate 18, when the connecting frame 16 moves leftward, the movable plate 17 will first squeeze and trigger the pressure contact switch 31. Then the electromagnetic push rod 26 is electrified and remains in the extended state. The extension of the electromagnetic push rod 26 can make the support plate 8 rotate upward, and the support plate 8 maintains a horizontal state to block the material outlet 7. When the connecting frame 16 moves leftward, the movable plate 17 and the pushing plate 18 will be driven to move leftward synchronously. The lowermost placing plate 20 can be pushed leftward above the support plate 8 by the pushing plate 18. At the same time, the leftward movement of the sliding sleeve 12 can drive the mounting frame 10 to move above the support plate 8; Then the first electric telescopic rod 11 is started to extend, driving the mounting frame 10 to move downward above the placing plate 20. The mounting frame 10 contacts the placing plate 20. At this time, the material taking cylinder 34 is inserted into the interior of the placing groove 23. The negative pressure pump 32 is started, and negative pressure can be generated in the material taking cylinder 34. The drug sensitivity paper 24 in the placing groove 23 is sucked to the lower end of the material taking cylinder 34 through the material taking cylinder 34. Then the first electric telescopic rod 11 is contracted, driving the mounting frame 10 to move upward; Then start the secondary contraction of the second electric telescopic rod 14 to drive the sliding sleeve 12 to continue moving leftward, so that the mounting frame 10 moves above the positioning ring 5. At the same time, the push plate 18 can be limited by the stop bar 19 to keep the push plate 18 stationary. And since the spring 29 can be compressed, the movable plate 17 can continue to move inside the movable groove 28, thus not hindering the movement of the sliding sleeve 12. Then start the first electric telescopic rod 11 to extend, driving the mounting frame 10 to move down above the culture dish, stop the negative pressure pump 32, the negative pressure in the material taking cylinder 34 disappears, and the drug sensitivity paper 24 sucked at the lower end of the material taking cylinder 34 falls onto the culture dish. Then start the third electric telescopic rod 38 to extend, driving the second mounting plate 37 to move down, driving the pressing plate 39 to move down through the movable rod 36, and pressing and pasting the drug sensitivity paper 24 onto the surface of the culture dish through the pressing plate 39, and then start the third electric telescopic rod 38 to contract; Then start the first electric telescopic rod 11 to contract, driving the mounting frame 10 to move up and reset. Then start the second electric telescopic rod 14 to extend, driving the sliding sleeve 12 to move rightward and reset, driving the movable plate 17 and the push plate 18 to move rightward and reset through the connecting frame 16. Finally, the movable plate 17 is separated from the pressure contact switch 31, the pressure contact switch 31 is not triggered, the electromagnetic push rod 26 is powered off and contracts, and the support plate 8 rotates downward to open, so that the placement plate 20 that has used up the drug sensitivity paper 24 automatically falls into the collection box 3 through the material discharge port 7 for collection.

[0026] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
