In this embodiment, the material is exemplified by a reaction cup 700, and the reaction cup 700 is a container for providing a sample, adding a reagent, reacting, mixing, and detecting to an instrument. The storage bin 200 is used for loading the reaction cups 700, and a window is arranged on the storage bin 200 for enabling the reaction cups 700 to flow out at a constant speed through an internal mechanism, so that the storage bin 200 can be used for observing the allowance and the state of the reaction cups 700 in the storage bin 200. The sequencing runner 300 is positioned at the discharge end of the bin 200, the reaction cup 700 slides in from the side surface of the sequencing runner 300 after being screened out and jacked by the jacking piece 400, the flanging of the outer edge of the reaction cup 700 is clamped on the upper edges of the side walls at two sides of the sequencing runner 300, and the reaction cup 700 is changed into a vertical state by self weight; the sequencing channel 300 is of sufficient length to accommodate a row of reaction cups 700 simultaneously for subsequent assembly.

Wherein, the feeding slit 401 is a strip-shaped long hole obliquely arranged, and is from one end of the material ejecting member 400 to the other end close to the inner side wall of the storage bin 200, and the height position of the feeding slit 401 is gradually reduced. Thus, the reaction cup 700 entering the feeding slit 401 can keep an inclined posture, and the subsequent entering of the sequencing channel 300 is facilitated. The number of the reaction cups 700 is limited by the ejection piece 400 through the feeding slit 401, so that when the ejection piece is positioned at the bottom of the bin, only one reaction cup 700 can slide into the feeding slit 401, and the ejection piece 400 is ensured to eject only one reaction cup 700 at a time without causing failure due to abnormal conditions. In addition, due to the arrangement of the feeding slit 401, the reaction cup 700 entering the feeding slit 401 can only be in a lying posture, so that the posture of the reaction cup 700 during jacking is ensured to be determined, and abnormal sound caused by collision can not occur. Since the reaction cup 700 is positioned in the feeding slit 401 when being jacked up, the reaction cup 700 is protected and cannot be pinched.

Specifically, referring to fig. 3, in this embodiment, the left side wall of the feeding slot 401 has a notch, and the reaction cup 700 in the feeding slot 401 cannot slide out of the left notch due to the limitation of the bevel guide strip 603 during the ascending process of the ejector 400; referring to fig. 4, in this embodiment, the right side wall of the feeding slit 401 has a notch, and since the feeding slit 401 is inclined and the right side is higher than the left side, the reaction cup 700 in the feeding slit 401 cannot slide out of the notch of the right side by the inclination of the feeding slit 401 during the ascending process of the ejector 400; referring to fig. 5, in this embodiment, two opposite side walls of the feeding slit 401 are closed, so that the feeding slit 401 is a parallelogram, and when the ejector 400 is at the bottom of the bin, the reaction cup 700 slides into the feeding slit 401 from the side, and when the ejector 400 rises to the inlet of the sequencing channel 300, the reaction cup 700 slides into the sequencing channel 300.

In some embodiments, the width of the feed slit 401 is larger than the outer diameter of a single material and smaller than the sum of the outer diameters of two materials stacked in a lying position.

In some embodiments, the guiding surface structure includes a second guiding surface 401a disposed on an inner wall of the top end of the feeding slit 401 for pushing away the excessive material when the ejector 400 descends, and the second guiding surface 401a is an inclined surface facing away from the sorting flow channel 300. Specifically, referring to fig. 3, when the feeding slit 401 of the ejector 400 is empty, the ejector 400 moves downward, and the second guide surface 401a can push away the more than 1 reaction cup 700, so as not to block the downward reset movement of the ejector 400, and avoid the occurrence of jamming.

In some embodiments, the guiding surface structure comprises a third guiding surface 401b disposed on at least one inner sidewall of the feeding slit 401 for sliding the single material into the feeding slit 401, the third guiding surface 401b is an inclined surface facing away from the sequencing channel 300, and the third guiding surface 401b extends in a direction close to the feeding slit 401.

Specifically, the bottom of the ejector 400 is provided with a clamping block 402, and the ejector 400 is clamped on a transmission belt 503 through the clamping block 402 and moves along with the transmission belt 503. The lifting movement of the material ejecting member 400 is realized by controlling the forward and reverse rotation of the driving motor 501.

In some embodiments, the lifting mechanism further comprises a guide rail 601 assembly, wherein the guide rail 601 assembly comprises a guide rail 601 arranged on the frame 100 and a sliding block 403 arranged on the ejection piece 400, and the ejection piece 400 is lifted and lowered along the guide rail 601 by the sliding block 403.

In some embodiments, the ejector 400 is provided with a striker rod 404, and the striker rod 404 moves together with the ejector 400. Specifically, the material blocking rod 404 is located at one side of the material pushing member 400, and is fixed on the material pushing member 400 to perform reciprocating lifting movement along with the material pushing member, so that each reaction cup 700 is blocked by the material blocking rod 404 after entering the sorting flow channel 300, and the reaction cups 700 continue to slide downwards after being uniformly adjusted to be in a vertical state, thereby avoiding the reaction cups 700 from being jammed by rolling in the sorting flow channel 300 and causing faults.

In this way, the posture of the cuvette 700 can be adjusted to a posture parallel to the top member 400 by the up-and-down movement of the disturbance member 602 so as to slide into the feeding slit 401 of the top member 400.

In some embodiments, the bottom end of the material jacking member 400 is provided with a pushing member 405 for pushing the disturbing member 602 upwards, and the disturbing member 602 enters the bin 200 under the action of the pushing member 405 and exits the bin 200 under the action of its own weight and the material in the bin. Specifically, the pusher 405 moves with the ejector 400, thereby transferring the power of the movement of the ejector 400 to the perturber 602. In the initial state, the ejector 400 is at the lowest position, and a distance is reserved between the pushing member 405 and the disturbing member 602; when the material ejecting part 400 moves upwards to a certain height, the pushing part 405 contacts with the disturbing part 602 and drives the disturbing part 602 to move upwards to enter the storage bin 200, and the posture of the reaction cup 700, which is vertical to the material ejecting part 400, at the bottom of the storage bin is adjusted to be in a parallel state; when the ejector 400 moves downwards, the pushing part 405 is separated from the disturbing part 602, and the disturbing part 602 exits the bin 200 and falls onto the rack 100 under the action of the self-weight and the extrusion of the bin material.
