[0028] In the embodiment, the bottom end of the base 1 is provided with wheels 9 at four corners, which are self-locking universal wheels, so that the device can be moved conveniently, and the position of the device can be transferred conveniently, improving the convenience of the device in use.

[0029] In the embodiment, the lifting assembly includes a second motor 10, a screw rod 11, a guide rod 12, and a lifting plate 13. The second motor 10 is arranged at the top end of the rack 2, and the output end of the second motor 10 extends into the inner chamber of the rack 2. One end of the screw rod 11 is rotatably connected to the top end of the base 1 through a bearing, and the other end of the screw rod 11 is fixedly connected to the output end of the second motor 10. The guide rod 12 is arranged in the inner chamber of the rack 2. The lifting plate 13 is screwed to the outer wall of the screw rod 11 and slidably sleeved on the outer wall of the guide rod 12. The lifting plate 13 is fixedly connected to the rear end of the connecting plate 3. Starting the second motor 10 drives the screw rod 11 to rotate. Under the action of the thread rotation force on the outer wall of the screw rod 11, when the screw rod 11 rotates, the lifting plate 13 slides downward along a straight line under the limiting action of the guide rod 12, so that the bottom end of the drill bit 6 contacts the ground, and the drill bit 6 drills into the ground for coring.

[0030] In the embodiment, the pushing assembly comprises a driving assembly, a lead screw 16, a moving cylinder 18 and a limiting assembly.
