[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a concrete core sample picking device, including an equipment box 1, a drive box 2 at the top of the equipment box 1, a rotating groove 3 at the bottom of the drive box 2, a rotating shaft 4 rotatably connected to the rotating groove 3, an extraction tube 5 rotatably connected to the bottom of the rotating shaft 4, a pair of first limiting tubes 6 on both sides of the extraction tube 5 in the equipment box 1, a movable groove 7 at the bottom of each pair of first limiting tubes 6, and a second limiting tube 8 movably connected to each pair of first limiting tubes 6 through the movable groove 7, and handles 9 on both sides of the equipment box 1.

[0028] The drive box 2 has a drive slot 10, and a motor 11 is installed in the drive slot 10. The motor 11 can easily drive the rotating shaft 4 to rotate.

[0029] The top end of the rotating shaft 4 passes through the top end of the rotating groove 3 and extends into the drive groove 10. The output end of the motor 11 is connected to the end of the rotating shaft 4 that extends into the drive groove 10 via a coupling.

[0030] The top of the drive box 2 is provided with several heat dissipation holes 12, which can conveniently dissipate heat from the motor 11.

[0031] The bottom end of the movable groove 7 is provided with a compression spring 13, and the second limiting tube 8 is provided with a limiting block 14 at one end of the movable groove 7. The compression spring 13 is located between the top end of the movable groove 7 and the top end of the limiting block 14.

[0032] The second limiting tube 8 is provided with a support block 15 at its bottom end, which can stably support the entire device.

[0033] The bottom end of the extraction tube 5 is provided with an insertion ring 16, which facilitates the insertion of the extraction tube 5 into the hole of the concrete core sample.

[0034] The device box 1 has a controller 17 on one side, which can conveniently operate the entire device.

[0035] The working principle of this embodiment is as follows: When using this utility model, the operator places the device in a suitable position, ensuring that the insertion ring 16 is inserted into the hole of the concrete core sample. Then, the operator starts the entire device by operating the controller 17. The motor 11 receives an electrical signal and drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the extraction tube 5 to rotate. The insertion ring 16 thus drives the extraction tube 5 into the hole. At this time, the operator holds the handle 9 and continuously presses the entire device down. As the device is pressed down, the limiting block 14 squeezes the compression spring 13 in the movable groove 7. The entire device is thus driven to move downward, and the extraction tube 5 thus rotates and extracts the concrete core sample.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
