Through the coordinated use of the drilling mechanism, the single-axis motor drives the drill barrel and the drill gear ring to rotate synchronously at high speed, and the double-axis motor drives the gear to roll downward along the rack groove. During the downward movement of the single-axis motor, it drives the drill barrel, the drill gear ring and the circular through hole to perform drilling sampling operations. At the same time, it drives the elliptical ring to slide downward along the elliptical through hole and drives the spiral water pipe to stretch, thereby completing the drilling sampling operation on the ground.

[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] The present application embodiment discloses a core sampling machine. Figure 1 The core sampling machine includes an automatic coring sampling device 1, which includes a tracked vehicle body 11, a limiting bracket 12, a movable frame 13, a positioning shaft 14, a drill barrel 15, a drill gear ring 16 and a lifting assembly 17. The outer side of the tracked vehicle body 11 is fixedly connected to one end of the limiting bracket 12, the movable frame 13 is slidably sleeved inside the limiting bracket 12, the positioning shaft 14 is rotatably connected to the outer side of the movable frame 13, the drill barrel 15 is fixedly connected to the bottom of the positioning shaft 14, the drill gear ring 16 is welded and fixed to the bottom of the drill barrel 15, the lifting assembly 17 is arranged on the inner side of the movable frame 13, and a coring assembly 2 is also arranged inside the drill barrel 15.
[0032] The coring assembly 2 includes a carbide plate 21, a blind hole 22 and a limit spring 23. The blind holes 22 are arranged in a circular array at the bottom of the drill barrel 15. The carbide plate 21 is slidably sleeved on the inner side of the bottom of the drill barrel 15. The two sides of the limit spring 23 are fixedly connected to the carbide plate 21 and the inner wall surface of the drill barrel 15 respectively.
[0033] The lifting assembly 17 includes a stepper motor 171, a threaded rod 172 and a linear shaft 173. The stepper motor 171 is threadedly connected to the middle of the top end of the limit bracket 12. The top of the threaded rod 172 passes through the inner wall of the limit bracket 12 and is fixedly connected to the motor shaft of the stepper motor 171 through a coupling. The linear shafts 173 are symmetrically distributed on both sides of the threaded rod 172.
[0034] The movable frame 13 is respectively penetrated with a thread groove 3 and a through hole 4 that match the sizes of the threaded rod 172 and the linear shaft 173 .
[0035] Hydraulic buffers 5 are also fixedly connected to both sides of the movable frame 13 .
[0036] The outer side of the movable frame 13 is also provided with a motor body 6, a driving shaft 7, a large belt pulley 8, a small belt pulley 9 and a belt body 10.

The hydraulic buffer 5 can play a buffering effect during the lifting process, and cooperate with the motor body 6 to complete the stable drilling of the drill tube 15, thereby ensuring the drilling accuracy; the motor body 6 at the top is electrically started, and its output shaft drives the drive shaft 7 to rotate, and the drive shaft 7 drives the starting large leather The belt pulley 8 rotates, and the power is transmitted from the large belt pulley 8 to the small belt pulley 9 through the outer belt body 10, thereby completing the speed-up rotation, and cooperating with the drill tooth ring 16 at the bottom to complete the efficient drilling effect on the bottom surface; on the other hand, as the drill barrel 15 is gradually extended, the top of the drill core contacts the carbide plate 21, and the wedge-shaped carbide plate 21 squeezes the limit spring 23 inward along the inside of the blind hole 22. Under the elastic support of the spring, the drill core located inside the drill barrel 15 gradually rises and increases the contact area with the carbide plate 21, thereby enhancing the clamping force; then the drill barrel 15 is lifted, and multiple groups of carbide plates 21 are pressed against the surface of the drill core to synchronously complete the automatic extraction operation, thereby improving the practicality of the device.
