[0021] In this embodiment, when the sampling device is pushed, the roller rolls due to the force, and drives the gantry 1 to move, so that the sampling device can be moved for use. If the sampling device moves to the sampling area, the insertion rod 3 is rotated to rotate and move downward and extend to the inside of the rock and soil, so that the sampling device can be fixed, thereby improving the stability of the sampling device during operation.

At this time, the rock and soil sampling tube 8 slowly enters the interior of the rock and soil, so that the rock and soil can be squeezed into the rock and soil sampling tube 8, thereby facilitating the sampling of the rock and soil.

[0024] See also Figure 2 and Figure 3 The rock and soil sampling tube 8 is movably sleeved with a push plate 9, which is in the shape of a disc, and the outside of the push plate 9 is adapted to the inside of the rock and soil sampling tube 8.

When the sampling device moves to the sampling area, the insertion rod 3 is rotated to rotate and move downward, and extend to the inside of the rock and soil, so that the sampling device can be fixed, thereby improving the stability of the sampling device when working;

[0027] Then, the driving motor 6 is turned on to rotate the mounting frame 7, and the mounting frame 7 drives the rock sampling tube 8 to rotate, and then the electric hydraulic rod 4 is started to extend, and the electric hydraulic rod 4 drives the protective cover 5 to move vertically downward, so that the mounting frame 7 and the rock sampling tube 8 rotate and move downward, and the rock sampling tube 8 slowly enters the interior of the rock soil, so that the rock soil can be squeezed into the rock sampling tube 8, so as to facilitate the sampling of the rock soil;
