Working principle: as shown in fig. 1, a plurality of chromatographic specimen bottles 5 loaded with waste liquid are placed in a vibration plate 100, and the vibration plate 100 is operated by a controller 6. The vibration plate 100 makes the chromatographic sample bottles 5 enter the feeding channel 101, a plurality of chromatographic sample bottles 5 are sequentially arranged, rise up along the feeding channel 101 and enter the upper end of the slideway 102 from the feeding notch 103, at this time, the chromatographic sample bottles 5 have two states, namely, the bottle cap is in the lower state, the bottle body is in the upper state, and the bottle cap is in the upper state and the bottle body is in the lower state.
As shown in fig. 2 to 4, under the action of gravity, the chromatographic sample bottle 5 rolls down along the slideway 102, the chromatographic sample bottle 5 with the bottle cap on, the annular groove between the bottle body and the bottle cap just corresponds to the rib 112, the downward rolling is continued, the time from passing under the first distance sensor 113 is very short, the time of the signal generated on the first distance sensor 113 is very short (for example, 0.2 s), and the time of the signal received by the controller 6 is short without any instruction; the chromatographic sample bottle 5 with the bottle cap below and the ribs 112 prop against the bottle body, so that the chromatographic sample bottle 5 cannot roll downwards, the chromatographic sample bottle 5 stays at the ribs 112 for a longer time (for example, more than 1 s), the first distance sensor 113 outputs a longer-time signal to the controller 6, and the controller 6 receives the longer-time signal and then enables the first air cylinder 109 to extend and retract rapidly through the first electromagnetic valve 110.

Preferably, the cap is prevented from stacking, and the first bracket 118 should be provided with a hole for the cap to pass through when it is dropped. The remaining bottles can pass through the lower side of the limiting piece 127 and continue to roll down until falling out from the lower end of the slideway 102, and a container for collecting the bottles can be placed at the lower end of the slideway 102.
