[0048] A top slot 37 is provided on the top of the annular disc seat 1, and a universal driving part is installed in the top slot 37. The universal driving part is in driving connection with the drilling sampling assembly.

The inverted cone counterweight ring 6 is threadedly connected to the outer wall of the drilling sampling assembly.

[0049] A clearance groove 8 is provided at the bottom of the annular disc seat 1, and the clearance groove 8 facilitates the inclination angle of the drilling sampling component.

[0050] Further optimized solution, the friction limiting part includes a friction pressure plate 21, the friction pressure plate 21 is vertically slidably connected with a friction pressure plate slide groove 35, the friction pressure plate slide groove 35 is coaxially opened in the annular disc seat 1, the friction pressure plate slide groove 35 is located above the inverted conical slot 2, a plurality of connecting rods 23 are fixedly connected to the top of the friction pressure plate 21 at equal intervals in the circumferential direction, the connecting rods 23 are vertically slidably connected to the annular disc seat 1, the tops of the plurality of connecting rods 23 are fixedly connected to the bottom of the pressure ring 20, the pressure ring 20 is vertically slidably connected to the annular disc seat 1, and the pressure ring 20 is limited by two symmetrically arranged limiting parts, and the limiting parts are arranged in the annular disc seat 1;

[0052] According to a further optimized solution, the limiting portion includes a horizontal sliding groove 18, the horizontal sliding groove 18 is arranged in the annular disc seat 1, and the two horizontal sliding grooves 18 are symmetrically arranged;

[0053] A sliding plate 17 is horizontally slidably connected in the horizontal sliding groove 18, and the sliding plate 17 is coaxially fixed with a limit rod 16.

[0054] When in use, the friction pressure plate 21 is separated from the top of the right conical sliding ring 3, so that the right conical sliding ring 3 can slide horizontally in the inverted conical slot 2.

[0055] Under the action of gravity, the inverted conical counterweight ring 6 will automatically make the axial direction of the middle through groove parallel to the direction of gravity. At this time, the plurality of slide rods 5 spherically hinged on the top of the inverted conical counterweight ring 6 will vertically slide to different degrees relative to the annular disc seat 1, so that each ball head 4 has different degrees of extrusion on the side wall of the right circular conical sliding ring 3, so that the right circular conical sliding ring 3 slides relative to the inverted conical slot 2. When the inverted conical counterweight ring 6 is stable, the pressing ring 20 is pressed, and the friction pressure plate 21 is pushed to contact the top of the right circular conical sliding ring 3 through each connecting rod 23.

[0057] A driving part is arranged inside the inner rotating ring 11, and a drilling sampling assembly passes through the center of the driving part, and the drilling sampling assembly is in driving connection with the driving part.

The outer walls of the drill rod 32 and the extension rod 33 are both provided with keyways that cooperate with the radial limiting of the limit block 7, and the keyways are vertically slidably connected to the limit block 7.

[0061] The drill rod 32 first slides through the rotor 9 . A keyway matching the stop block 7 is provided on the drill rod 32 . The keyway is used to make the drill rod 32 rotate synchronously with the rotor 9 .

The rotation direction of the inner rotating ring 11 is perpendicular to the rotation direction of the outer rotating ring 12 in space, so that the drill rod 32 or the extension rod 33 in the middle of the rotor 9 can be directed in any direction, which is convenient for adjusting the angle of the rotor 9 so that its central axis is on the same straight line as the central axis of the inverted cone counterweight ring 6, thereby facilitating the passage of the drill rod 32 and the extension rod 33.

The four wheels 26 are rotatably connected to the four corners of the bottom of the vehicle body 24, and the four hydraulic struts 25 are fixedly connected to the four sides of the vehicle body 24. The four wheels 26 and the four hydraulic struts 25 are arranged at intervals.

[0069] The vehicle body 24 can be easily moved by means of four wheels 26. When the vehicle body 24 is moved to a designated position, the four hydraulic struts 25 are extended to lift up the vehicle body 24, thereby preventing the vehicle body 24 from moving during the sampling process.
