[0015] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0016] In conjunction with the accompanying drawings, a geological exploration sampling device includes a base 1, a shell 2 is threadedly connected to the base 1, a sampling tube 3 is fixedly arranged inside the shell 2, the inner wall of the shell 2 abuts against the outer ring of the sampling tube 3, the shell 2 is flush with the top of the sampling tube 3, the outer ring of the shell 2 is threadedly connected to a screw sleeve 4 near the top, the bottom of the screw sleeve 4 abuts against the top of the sampling tube 3, a rotating shaft 5 is fixedly arranged on the inner wall of the sampling tube 3 near the bottom, and the outer ring of the rotating shaft 5 is rotatably connected to the first baffle 6 and the second baffle 7.

[0017] The shell 2 is provided with a limit groove array on the top, and the outer ring of the sampling tube 3 is provided with a limit block 8 near the top array. The limit block 8 abuts against the inner wall of the corresponding limit groove, and the bottom of the screw sleeve 4 abuts against the top of the limit block 8. The shell 2 and the sampling tube 3 are fixed by this structural design.

[0018] The inner wall of the sampling tube 3 is symmetrically provided with a stopper 9 near the bottom, and the bottoms of the first baffle 6 and the second baffle 7 are respectively abutted against the tops of the corresponding stoppers 9. The first baffle 6 and the second baffle 7 are arranged in a semicircular shape, and the arc surface abuts against the inner circle of the sampling tube 3. The first baffle 6 and the second baffle 7 are limited by this structural design.
