[0003] Existing methods for rock and soil sampling usually use drilling surveys, which require the use of a drilling machine to drill holes in the rock and soil. After sampling once, the drill bit needs to be pulled out, along with the rock and soil at the corresponding depth, to complete the sampling process. However, existing sampling equipment cannot continuously sample rock and soil at different depths, and when the staff separates the rock and soil samples from the sampling cavity, the sampling and survey work efficiency is low because the samples fit tightly with the sampling cavity.

The soil sample depth line (15) on the outside of the sample filling seat (6) records the depth of the collected soil sample. The soil sample with a deep depth is continuously accumulated on the upper side of the sample filling seat (6). S3: When the sleeve (4) rotates, the first protrusion (402) and the second protrusion (111) on the swing plate (11) move against each other, so that the swing plate (11) moves upward when a force is applied, and moves downward under the action of its own gravity when no force is applied, so that the swing plate (11) moves up and down reciprocatingly, so that the soil sample entering the feed port (501) is in a vibrating state, so that the soil sample does not block the feed port (501); S4: After the rock and soil sampling is completed, the hydraulic cylinder (2) drives the sleeve (4) to reset and move. After the side surface of the main seat body (601) no longer contacts the inner wall of the annular frame (13), the main seat body (601) moves toward the outside of the sample collecting shell (5) under the action of the elastic element (502). During this period, the movable gear (142) on the rotating rod (14) is meshed with the rack plate (503) on the sample collecting shell (5) for transmission. When the rotating rod (14) rotates, it drives the cam (503) to rotate. The wheel (141) intermittently abuts against the push plate (602), so that the push plate (602) pushes the soil sample collected in the main seat body (601) back and forth, so that the collected soil sample is compacted, and the soil sample removed from the sample collecting shell (5) with the main seat body (601) will not loosen and fall off, and the soil sample in the main seat body (601) will not occupy too much internal space of the cavity of the main seat body (601) after being squeezed, so that the staff can conveniently take samples from the cavity in the main seat body (601) for testing and investigation.
