[0023] See also Figure 1-2 The limiting sleeve 46 is rotatably arranged on the upper outer side of the drill tube 32, and the threaded drill rod 44 is located at the central axis position of the drill tube 32. When the threaded drill rod 44 rotates, it can drill into the core body to fix the core body, making it convenient to take out the core body.
[0024] See also Figure 3 In the embodiment of the utility model, the drilling member 3 includes a drill barrel 32 and a drilling motor 31 fixedly installed on the inner side of the L-shaped seat 2.

[0025] See also Figure 1 In the embodiment of the utility model, the highway coring device also includes a base 1, a first servo motor 101 is installed inside the base 1, the output shaft of the first servo motor 101 is connected to a screw 102, a convex plate 21 is arranged on the back side of the L-shaped seat 2, and the convex plate 21 is screwed to the outside of the screw 102 through a thread.

[0028] After the drilling is completed, the second servo motor 43 drives the threaded drill rod 44 to rotate, and the hydraulic cylinder 45 drives the second servo motor 43 to move downward. The second servo motor 43 will drive the limit plate 42 to move downward, and then the threaded drill rod 44 will move downward, so that the lower end of the threaded drill rod 44 can be drilled into the interior of the upper end of the core body, and then the L-shaped seat 2 is moved upward, and the L-shaped seat 2 will move the drill tube 32 upward. Since the lower end of the threaded drill rod 44 is drilled into the core body, the threaded drill rod 44 will bring the core body out;
[0029] Then, the second servo motor 43 drives the threaded drill rod 44 to reverse, and at the same time, the hydraulic cylinder 45 drives the second servo motor 43 to move upward, so that the threaded drill rod 44 will slowly drill out of the core body. If the core body rotates together with the threaded drill rod 44, the upper end of the core body can be supported by a tool such as a stick or a steel bar. When the threaded drill rod 44 is completely drilled out of the core body, the core body in the drill barrel 32 is pushed down to take out the core body.
