specifically, one end of the sleeve 13 is connected with the inner side of the top of the cylinder 1, and the other end of the sleeve is abutted against the action wheel 431, so that the action wheel 431 can be limited by the sleeve to not displace in the axial direction; the driving device 432 and the positioning wheel 434 are oppositely arranged on two sides of the action wheel 431, so that the radial displacement of the action wheel 431 is limited through the matching of the driving device 432 and the positioning wheel 434; therefore, when the driving device 432 operates to drive the driving wheel 433 to rotate, the driving wheel 431 can be driven to rotate; because the action wheel 431 is in threaded connection with the action rod 41, when the action wheel 431 rotates at a limited position, the action rod 41 is driven to rotate, so that the action rod 41 drives the sampling disc 42 to act in the axial direction; in the invention, in an initial state, the sampling disc 42 is positioned at the bottom of the sampling space 11, when the action rod 41 rotates, the sampling disc 42 is driven to rotate, the sampling disc 42 gradually moves towards the direction far away from the bottom of the sampling space 11, and under the action of the sampling disc 42, a sample enters the sampling space through the liquid inlet 2;

as shown in fig. 2, the sampling disc 42 is adapted to the inner wall of the cylinder 1, so that when the sampling disc 42 is driven by the actuating rod 41 to move, the sampling disc 42 generates a suction force, so that the sample enters the sampling space 11 through the liquid inlet 2 under the action of the suction force; to increase the suction force, in the present invention, it is preferable to provide a sealing ring 44, the sealing ring 44 being provided on the outer surface of the sampling plate 42; the sealing ring 44 is preferably a rubber sealing ring 44, so that the sealing between the sampling disc 42 and the interior of the cylinder 1 is increased or decreased, and when the sampling disc 42 is driven by the action rod 41 again to act, the generated suction force is larger, so that the sample entering efficiency is better;

of course, since the sleeve 13 collides with the action wheel 431 and the action wheel 431 rotates under the driving of the driving device 432, friction between the action wheel 431 and the sleeve 13 is caused, on one hand, the sleeve 13 and the action wheel 431 are damaged, on the other hand, the power consumption of the driving device 432 is affected due to the generation of friction, and therefore, the first buffer group 435 is disposed between the sleeve 13 and the action wheel 431; the friction force between the sleeve 13 and the action wheel 431 is buffered by the first buffer group 435, so that the action wheel 431 and the sleeve 13 are prevented from being damaged, and the power consumption of the driving device 432 is reduced;

the first buffer group 435 includes a pressure plate 4351, a fixed plate 4352, balls 4353 and a raceway 4354, the pressure plate 4351 is fixedly connected with one end of the sleeve 13, the fixed plate 4352 is fixedly connected with the top surface (the surface adjacent to the sleeve 13) of the action wheel 431, the opposite surfaces of the pressure plate 4351 and the fixed plate 4352 are both provided with annular grooves, the annular grooves form the raceway 4354 after the pressure plate 4351 and the fixed plate 4352 are combined, and the raceways 4353 are arranged in the raceway 4354; thus, when the action wheel 431 is driven by the driving device 432 to rotate, the friction force between the pressure plate 4351 and the fixed plate 4352 can be buffered through the balls 4353 in the raceway 4354;

in addition, the action wheel 431 generates friction with the bottom of the installation space 12, and in order to reduce the friction force, a second buffer group is preferably arranged between the action wheel 431 and the bottom of the installation space 12; the friction between the action wheel 431 and the bottom of the installation space 12 is reduced through the second buffer group; in the present invention, the second buffer group can have the same structure as the first buffer group 435, and therefore, the present invention is not further described herein;

according to the technical scheme, the control group 6 is arranged in the barrel 1, the control group 6 is used for acquiring signals of the detection group 5 to acquire the position information of the liquid inlet 2 on the barrel 1, the balance group 3 is further controlled to act, the barrel 1 is maintained at the designated position through the balance group 3, and the sampling group 4 is controlled to act, so that the sampling group 4 sucks a sample at the position into the barrel 1 to finish sample collection.
