When sampling, the filter portion 40 can filter impurities in the sample, which is convenient for subsequent maintenance and cleaning.

[0031] Specifically, before sampling, the sampler 28 is vacuumed, that is, the indexing motor 18 is operated to rotate the rotating plate 34, and then the samplers 28 in all directions are rotated to the bottom of the docking part 6 in turn, and the docking part 6 is moved by controlling the electric cylinder 7 to make the docking part 6 dock with the control valve 31 to achieve communication, and the vacuum pump 5 is operated to complete the vacuuming process; the control valve 31, the control valve 29 on the sampler 28, and the control valve 3 43 at the bottom of the assembly seat 41 can be controlled.
