After the connection relationship is processed, the driving motor 4 can be started through the controller 13. The driving motor 4 runs and drives the sampling cylinder 7 to rotate through the rotating shaft rod 5, and feeds this device vertically downward to the ground. The cutter group at the bottom of the sampling cylinder 7 will cut the soil layer for sampling. During the sampling process, stable buffering can be carried out. First, the long column rod 17 will plunge into the ground. As this device feeds downward, the second spring 18, the connecting rod 14, and the guide post 15 will cooperate with each other for buffering. After the long column rod 17 plunges into the ground, it will fix this device. This mechanism can effectively carry out stable buffering for this device, increase the stability of this device, avoid the situation of out-of-control caused by the rotation deviation or large vibration amplitude of the device, and at the same time reduce the working intensity and prevent discomfort of the workers, thus completing the stable buffering process. After sampling, the strip-shaped dial 11 can be pushed. The strip-shaped dial 11 drives the guide rod 9 to move downward. During the downward movement, the stopper on the guide rod 9 will cooperate with the mounting block 8 to squeeze the first spring 12. At this time, the guide rod 9 will push the sampled soil out through the mud discharge plate 10.
