The end of the support column 15 away from the spring 16 can be completely located in the inner cavity of the movable groove. At this time, the sample bag on the other end of the support column 15 can automatically detach from the sample fixing structure.

[0024] An electromagnet 3 is fixed on the top of the box 1. When the electromagnet 3 is energized, it is magnetically attracted to the support column 15. By setting the electromagnet 3, when the support column 15 and the electromagnet 3 are on the same straight line, the sample can be automatically detached by controlling the on and off of the electromagnet 3.

[0025] A recycling chamber is provided on one side of the housing 1, and an opening and closing door is provided on the outside of the recycling chamber. The recycling chamber contains a sample recycling box 10 and a sample bag recycling box 11.

[0029] A sealing plate 21 is magnetically attracted to the side of the storage basket 20 away from the electric telescopic rod 13. The sealing plate 21 is movably connected to the inner cavity of the feed inlet, and the sealing plate 21 is magnetically attracted to the side of the feed inlet near the translation structure. With the setting of the sealing plate 21, when the storage basket 20 is located in the recycling chamber, the sealing plate 21 can block the feed inlet to prevent dust from leaking out of the recycling chamber. When the sealing plate 21 contacts the side of the feed inlet away from the electric telescopic rod 13, the end of the storage basket 20 connected to the electric telescopic rod 13 blocks the recycling chamber.

[0030] A dust suction ring 4 is fixed to the top of the feed inlet, and an exhaust fan 5 is provided on the box body 1. The air inlet of the exhaust fan 5 is connected to the dust suction ring 4, and the air outlet of the exhaust fan 5 is connected to an air filter box.

The following mainly introduces the working principle and process, and will not describe the electrical control.

[0033] In summary: When using this laboratory sample recovery device, the experimental sample is suspended by a sample fixing structure. When the sample needs to be discarded, the rotating track 2 moves the sample until it is above the inlet. The electromagnet 3 is then energized, and it magnetically attracts the support column 15 that suspends the sample. Under this attraction, the end of the support column 15 away from the spring 16 moves completely into the inner cavity of the movable slot. The sample bag falls into the inner cavity of the collection basket 20 under gravity. The electric telescopic rod 13 retracts, moving the collection basket 20 into the recovery chamber. At this time, the collection basket 20 is located below the ultrasonic cutter 17. The electric telescopic rod 3 moves the ultrasonic cutter 17 downwards, utilizing the ultrasonic cutter... 17. The sample bag is cut. After cutting, the electric telescopic rod 13 extends and retracts quickly, causing the collection basket 20 to shake. The sample can fall into the sample recovery box 10. The sample bag is intercepted by the filter screen 19. The translation structure moves the collection basket 20 to the top of the sample bag recovery box 11. The electric telescopic rod 29 extends, causing the filter screen 19 to move to the side of the collection basket 20. The sample bag falls into the inner cavity of the sample bag recovery box 11 under the action of gravity. During this process, the sample recovery is carried out in the sealed cavity, which reduces the harm of dust to laboratory personnel. If it is necessary to process the sample bag and the collected sample, before opening the door, the water spray plate 18 sprays atomized water to remove dust from the recovery cavity and wet the sample.
