When the user starts the dual-axis motor 13 to rotate in the opposite direction, the sampling cylinder 3 moves upward. When the limit plate 28 is engaged, the sample cylinder 3 moves upward. When the positioning plate 28 contacts the circular plate 7, the circular plate 7 pushes the push rod 27 through the limiting plate 28, and the push rod 27 drives the material stripping plate 26, so that the material stripping plate 26 moves downward inside the sampling tube 3, thereby pushing out the rock and soil samples inside the sampling tube 3.

While controlling the sampling tube 3 to lift and lower for sampling, it can also make the sampling tube 3 rotate to cut the rock and soil, reducing the resistance of the rock and soil to the sampling tube 3, and increasing the speed at which the sampling tube 3 enters the rock and soil, thereby improving work efficiency, and solving the problem that the existing foundation rock and soil detection and soil sampling device samples the rock and soil by extending the telescopic rod to press down the sampling tube 3, but the resistance of the rock and soil to the sampling tube 3 is large, resulting in the sampling tube 3 entering the rock and soil at a relatively slow speed, sampling is relatively inconvenient, and work efficiency is low.

[0036] When the user starts the dual-axis motor 13 for reverse rotation, the sampling tube 3 moves upward. When the limit plate 28 contacts the circular plate 7, the circular plate 7 pushes the push rod 27 through the limit plate 28. The push rod 27 drives the stripping plate 26, so that the stripping plate 26 moves downward inside the sampling tube 3, thereby pushing out the rock and soil samples inside the sampling tube 3. The rock and soil samples taken out by the sampling tube 3 can be automatically pushed out, thereby achieving the purpose of automatic material removal, solving the problem that the original foundation rock and soil detection and soil sampling device requires staff to use tools to take out the rock and soil samples from the sampling tube 3, which is poor in practicality.
