Referring to fig. 1 to 11, the working process of the sample collection device provided in the present embodiment will now be described in detail:

firstly, placing a reagent bottle group 9 at a clamping and fixing position on an advancing and extending component 4, wherein the advancing and extending component 4 drives the reagent bottle group 9 to move to a position to be taken in an advancing and extending direction, then a horizontal component 2 drives a bottle moving and sampling component 6 to move rightwards (relative to the position shown in figure 1) in the horizontal direction to a relevant position point, namely right above the position to be taken, and a vertical component 3 drives the advancing and extending component 4 to move to a relevant position in the vertical direction, namely, after the reagent bottle group 9 is inserted into the bottle moving and sampling component 6 and a reagent bottle cap of the reagent bottle group 9 is clamped by the bottle moving and sampling component 6, the vertical component 3 moves downwards to avoid interfering the horizontal movement of the bottle moving and sampling component 6; the horizontal component 2 drives the bottle moving sampling component 6 to move leftwards (relative to the position shown in fig. 1) in the horizontal direction to a position where the bottle moving sampling component 6 is rotating the rotating component 5, the vertical component 3 moves upwards until the reagent bottle bodies of the reagent bottle group 9 are inserted into the rotating component 7, and the reagent bottle bodies are clamped by the rotating component 7;

then, after the rotating component 7 rotates to unscrew the reagent bottle cap, the vertical component 3 moves downwards to separate the reagent bottle body from the reagent bottle cap; the bottle moving and sampling assembly 6 drives the reagent bottle cap and the collecting rod on the reagent bottle cap to swing until the collecting rod is over against the collecting hole 51 of the sample funnel 5, and then the horizontal assembly 2 moves to drive the collecting rod to insert a picture from the collecting hole 51 into the sample funnel 3 for sample collection; the horizontal component 2 drives the bottle moving sampling component 6 to return to the position right above the rotating component 7, then the bottle moving sampling component rotates to enable the collecting rod to face the reagent bottle body, and after the vertical component 3 moves upwards to enable the reagent bottle body to be in contact with the reagent bottle cap, the rotating component 7 rotates to screw the reagent bottle body and the reagent bottle cap tightly, so that a sample and a dissolving solution of the reagent bottle body are fully mixed to form a diluted sample;

finally, the vertical component 3 drives the rotating component 7 to move downwards, so that the bottle retreating needle 8 gradually approaches to the reagent bottle group, and meanwhile, the bottle retreating needle 8 is pressed against the bottom wall of the reagent bottle group and gradually presses the reagent bottle group, so that the reagent bottle group filled with the sample is retreated into the specified storage box.

To sum up, the sample collecting device provided by this embodiment drives the bottle moving sampling assembly 6 to perform position adjustment along the horizontal direction through position adjustment of the horizontal assembly 2 along the horizontal direction, and further drives the reagent bottle cap clamped by the bottle moving sampling assembly 6, the reagent bottle group 9 and the sampling rod on the reagent bottle cap to perform position adjustment along the horizontal direction, so that the reagent bottle group 9 is shifted from the extending assembly 4 to the rotating assembly 7, and the position movement of the reagent bottle cap and the sampling rod can be realized, so that the sampling rod is moved to the sampling position to perform sampling and can be moved back to the reagent bottle body of the rotating assembly 7; through the position control of vertical subassembly 3 along vertical direction to drive rotating assembly 7 and carry out position control along vertical direction, and then make reagent body press from both sides tightly to rotating assembly 7 on, and drive reagent body through rotating assembly 7 and rotate, realize twisting soon between reagent body and the reagent bottle lid and screw up or unscrew promptly, so that the sample of gathering on the sampling stick seals to reagent bottle group in. The device can gather the sample effectively, and convenient health just replaces the manpower, realizes not having the sample of artificial intervention and gathers, has guaranteed the effective and uniformity of the sample of gathering, has reduced the cost of labor, and can avoid personnel to receive influences such as stench, aerosol, virus when adopting.
