[0019] Specifically, the right end of the sampling tube 1 is fixedly connected with a fixing block 13, and the fixing block 13 is fixedly connected with the left end of the second rotating shaft 14. The second rotating shaft 14 is arranged in a second bearing 15, and the second bearing 15 is embedded in the surface of a fixing plate 16. A driving motor 18 is fixedly arranged on the side of the fixing plate 16 through a fixing frame 17. The output shaft of the driving motor 18 is fixedly connected with the right end of the second rotating shaft 14. The driving motor 18 is controlled to work by a control system (not shown in the figure). The output shaft of the driving motor 18 drives the fixing block 13 to rotate through the second rotating shaft 14, thereby making the sampling tube 1 and the drill bit 2 rotate.

[0020] Specifically, the upper and lower surfaces of the fixed plate 16 are fixedly connected with handles 19, and the outer surface of the handles 19 is provided with anti-slip sleeves 20. When using the sampling tube 1 for sampling, the staff can hold the handles 19 on both sides and cooperate with the drill bit 2 to make the sampling tube 1 go deep into the ground. The outer surface of the second protective plate 10 is fixedly connected with a shift block. The shift block is shifted to make the second protective plate 10 rotate with the first rotating shaft 5 on the rear side as the center of the circle, and enter the space between the baffle 11 and the sampling tube 1 to complete the release operation of the soil sample.

[0021] The working principle of the utility model is:

[0022] S1, first insert the drill bit 2 into the ground, then control the drive motor 18 to work through the control system, the output shaft of the drive motor 18 drives the sampling tube 1 to rotate through the second rotating shaft 14, and then the sampling tube 1 is made to penetrate into the ground through the rotation of the drill bit 2, and after the sampling tube 1 penetrates to a certain depth, the control system controls the drive motor 18 to stop working;

[0023] S2, then turn the knob 12 to make the first rotating shaft 5 on the front side drive the first protective plate 7 and the sampling shovel 8 to rotate, the first protective plate 7 is misaligned with the through hole 3 on the front side, and during the rotation process, one end of the sampling shovel 8 rotates out of the sampling tube 1 to scoop up the soil for sampling, and the scooped sample falls into the concave part on the rear side of the sampling tube 1, so that the first protective plate 7 blocks the through hole 3 again;

[0024] S3. Finally, after the sampling tube 1 is separated from the ground, the second protective plate 10 can be rotated around the first rotating shaft 5 by turning the shifting block, and the second protective plate 10 is misaligned with the through hole 3 on the rear side, so that the soil sample in the sampling tube 1 leaks out through the through hole 3 on the rear side, which is convenient for the staff to process the soil sample.
