[0018] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0019] like Figure 1As shown, a sampling mechanism for soil detection comprises a sleeve 1, a sampling slot 2 arranged in the sleeve 1 and lifted and lowered in the sleeve 1, and a cleaning mechanism arranged at the upper end of the sleeve 1 and rotated at the upper end of the sleeve 1. A guide hole 3 is arranged on the side wall of the sampling slot 2, a pedal rod 4 passing through the guide hole 3 is arranged at the upper end of the sampling slot 2, and a limit block 5 for limiting the downward movement of the pedal rod 4 is arranged in the guide hole 3. The limit block 5 has a clamping groove on both sides to clamp the side wall of the guide hole 3. The clamping groove cooperates with the side wall of the guide hole 3 to achieve the lifting and lowering guidance of the limit block 5. When working, the ground at the sampling position is first cleaned by the cleaning mechanism, and then the sleeve 1 is turned over, and the bottom of the sleeve 1 is supported on the ground to move upward. A person inserts the sampling slot 2 into the ground by stepping on the pedal rod 4 to complete the sampling operation. Sampling can be achieved with one tool, and the operation is convenient. The sampling depth is driven by adjusting the height of the limit block to ensure accurate sampling.
