When working, the flip mechanism 5 can drive the upper bin 2 to flip upward to be located above the feed port 12, so that the discharge port 23 is opposite to the feed port 12, so that the vacuum blood collection tubes arranged in the upper bin 2 enter the lower bin 1 from the discharge port 23; specifically, the sealing member 2 6 includes a sealing plate 261 arranged in the upper hopper body 21 and movable back and forth relative to the discharge port 23, and a sealing cylinder 262 arranged on the sealing plate 261 and connected to the outer side of the upper hopper body 21.

[0035] During operation, the flip mechanism 5 controls the upper bin 2 to flip downward and be arranged perpendicular to the lower bin 1, opens the upper chamber 22 through the flip cover 24, and places a plurality of vacuum blood collection tubes to be tested into the upper chamber 22. The positioning cylinder 252 controls the positioning plate 251 to move inward, clamping the plurality of vacuum blood collection tubes between the flip cover 24 and the positioning plate 251. The flip mechanism 5 then controls the upper bin 2 to flip upward and be arranged vertically opposite to the lower bin 1. At this time, the sealing cylinder 262 controls the sealing plate 261 to move outward to open the discharge port 23. The positioning cylinder 252 controls the sealing plate 261 to move outward to open the discharge port 23. The positioning plate 251 moves outward, causing multiple vacuum blood collection tubes to fall downward into the lower hopper 1; then the conveyor belt 41 is controlled by the rotating motor 42 to transport the vacuum blood collection tubes that have fallen to the top of the conveyor belt 41 outward to the feeding port 13. The vacuum blood collection tubes enter the feeding plate 32 from the feeding port 13 and enter the next device in the feeding trough 33 by gravity; through the above operations, the vacuum blood collection tubes are transported to the designated location in an orderly manner, which greatly improves the work efficiency of the laboratory, reduces the errors and costs caused by manual intervention, and ensures the safety and reliability of sample processing.
