[0027] According to an embodiment of the present invention, a soil and rock sampling device is provided.

[0028] Example 1;

[0029] like Figures 1-4 As shown, the soil and rock sampling device according to an embodiment of the present invention includes a fixed frame 1. A drive motor 2 is fixedly connected to the top of the fixed frame 1. A drive screw 3 is fixedly connected to the bottom of the output shaft of the drive motor 2. A movable sleeve 4 is threaded onto the outer wall of the drive screw 3. A movable frame 5 is fixedly connected to the outer wall of the movable sleeve 4. A slider 6 is fixedly connected to the outer wall of the movable frame 5. A fixed guide rail 7 is fixedly connected to the inner wall of the fixed frame 1. A connecting sleeve 8 is connected to the bottom of the movable sleeve 4 via a flange. A connecting pipe 9 is fixedly connected to the bottom of the connecting sleeve 8. A drill bit 10 is fixedly connected to the bottom of the connecting pipe 9. A receiving groove is opened inside the connecting sleeve 8. An electric push rod 12 is fixedly connected to the inner wall of the receiving groove. A piston block 13 is fixedly connected to the bottom of the movable end of the electric push rod 12.

[0030] The fixed guide rails 7 are arranged in a U-shape, and the movable frame 5 is slidably connected to the fixed guide rails 7 via the slider 6. This facilitates the sliding guidance of the slider 6 via the fixed guide rails 7, thereby improving the sliding stability of the movable frame 5. Specifically, there are two fixed guide rails 7 symmetrically distributed, further improving the sliding stability. As for how to discharge material, this utility model further explains that the connecting sleeve 8 is connected to the drill bit 10 via the connecting pipe 9, and a discharge pipe 11 is fixedly connected to one side of the connecting pipe 9, thus facilitating the discharge of the sample taken from inside the drill bit 10 through the connecting pipe 9 via the discharge pipe 11.

[0031] The piston block 13 is an elastic structure, and the outer wall of the piston block 13 is in contact with the inner wall of the connecting pipe 9, which facilitates the compression of air when the piston block 13 slides, thereby facilitating the extraction of samples. Specifically, the piston block 13 and the connecting pipe 9 form a sliding structure.

[0033] In practical applications, after the drill bit 10 completes sampling, the electric push rod 12 is activated, causing the electric push rod 12 to drive the piston block 13 to slide. After the piston block 13 slides, it drives the connecting pipe 9 to extract the sample inside the drill bit 10 and discharge it through the discharge pipe 11. This facilitates continuous sampling and effectively improves the convenience and efficiency of sampling.
