By driving the rotation of the first motor 5, the rotation of the turbine 7 can be driven by the worm 6, and then the hinge angle of the support seat 4 and the mounting seat 8 can be adjusted to achieve the angle adjustment of the propulsion module and the punching module.

[0023] Specifically, the lifting module also includes a lifting bracket 10, a first screw rod and a second motor 11.

The movement of the sliding block in the lifting bracket 10 is realized by driving the rotation of the second motor 11.

[0024] The propulsion module in this embodiment is used to control the drilling depth and can cooperate with the lifting module to further improve the applicability of the drilling device for tunnels of different heights. It includes a third motor 13, a second screw rod 14, a slide rod 15, a drill rod 20, a mounting frame 12, and a motor fixing platform 16. The mounting frame 12 is arranged on the mounting seat 8, the third motor 13 is arranged at the end of the mounting frame 12, the second screw rod 14 is rotatably arranged in the mounting frame 12, the output shaft of the third motor 13 is connected to the second screw rod 14 through a coupling, the slide rod 15 is fixedly arranged on both sides of the second screw rod 14, the motor fixing platform 16 is slidably arranged in the slide rod 15, and the motor fixing platform 16 is threadedly connected to the second screw rod 14.

[0026] As a preferred embodiment of the present invention, the drilling module includes a fourth motor 19 and a drill rod 20. The fourth motor 19 is arranged on the click fixing table, and the drill rod 20 is arranged at the output end of the fourth motor 19. A guide tube is arranged at the end of the mounting frame 12 corresponding to the drill rod 20 to improve the stability of the drill rod 20 during the drilling process.

[0027] The waste collection module is arranged at the top of the mounting frame 12, and is used for collecting gravel particles and dust during the drilling process. The waste collection module in this embodiment includes a barrel 21, a rotating closing mechanism, a plurality of sealing blocks 22, a compression spring 23 and a push rod 24. The barrel 21 is installed at the top of the mounting frame 12. The bottom of the barrel 21 is provided with a through hole for the drill rod 20 to pass through. The rotating closing mechanism is arranged at the top of the barrel 21. The top of the barrel 21 is provided with a slide groove. The sealing block 22 is slidably arranged in the slide groove. The bottom of the sealing block 22 is provided with a push rod 24. Limiting rods 25 are provided on both sides of the bottom of the sealing block 22. The sealing block 22 is installed on the top wall of the barrel 21 through the limiting rods 25. The limiting rod 25 is surrounded by a compression spring 23. A push rod 24 is provided in the middle of the sealing block 22. A ball 37 is provided at the bottom of the push rod 24, and the push rod 24 abuts against the rotating closing mechanism.

[0028] The present invention can ensure that the barrel 21 is pressed tightly against the arch of the tunnel by setting the sealing block 22, so that the dust or gravel generated during the drilling process can be completely dropped into the barrel 21, and the contact between the barrel 21 and the arch can be used to provide support for the drilling device, reduce vibration, and improve the stability of the drilling process. Especially when the inner diameter of the tunnel top is relatively small, resulting in an arc on the contact surface, multiple sealing blocks 22 are set as a structure that can be independently retracted to ensure that the sealing blocks 22 are completely fitted with the arch of the tunnel, avoiding the formation of gaps that cause dust to escape from the gaps.

[0029] As a preferred embodiment of the present invention, the rotary closing mechanism includes a mounting plate 26, a plurality of blades 27, a driving disk 28 and a reset mechanism.

[0030] The surface of the driving disk 28 is surrounded by a plurality of wave protrusions 32 corresponding to the push rod 24, and the upper surfaces of the plurality of wave protrusions 32 are smoothly lowered along the edge of the driving disk 28. An annular groove is provided below the barrel 21 corresponding to the push rod 24, and the wave protrusions 32 are located in the annular groove. The sealing block 22 can push the wave protrusions 32 to rotate by moving downward, that is, pushing the driving disk 28 to rotate.

[0031] A feed port is provided in the middle of the mounting plate 26 and the driving disk 28. The mounting plate 26 is arranged on the inner wall of the barrel 21. The driving disk 28 is rotatably arranged above the mounting plate 26. A vertical guide groove 29 is arranged around the lower surface of the driving disk 28. An outwardly inclined oblique guide groove 30 is arranged around the upper surface of the mounting plate 26. A plurality of blades 27 are slidably arranged between the driving disk 28 and the mounting plate 26. The blades 27 are fan-shaped. Limiting protrusions 31 are provided on the upper and lower surfaces of the blades 27, which are respectively located in the vertical guide groove 29 and the oblique guide groove 30. The driving disk 28 can drive the blades 27 to move when rotating, so that the blades 27 that are closed into a full circle to close the feed port move and hide between the driving disk 28 and the mounting plate 26. The reset mechanism is located at the edge between the driving disk 28 and the mounting plate 26, and is used for resetting the driving disk 28.

[0032] As a preferred embodiment of the present invention, the reset mechanism includes a limit ring 33 and a reset spring 34. A first limit baffle 35 is arranged around the edge of the upper surface of the mounting plate 26. The limit ring 33 is fixed in the first limit baffle 35. A second limit baffle 36 is arranged at the bottom of the driving disk 28. The second limit baffle 36 is slidably arranged in the limit ring 33. The reset spring 34 is arranged around the limit ring 33. One end of the reset spring 34 is fixedly connected to the first limit baffle 35, and the other end of the reset spring 34 is fixedly connected to the second limit baffle 36.

[0033] The sealing block 22 at the top of the barrel 21 of the present invention is in an extended state under the push of the compression spring 23. At this time, the return spring 34 is in a natural telescopic state, and the blade 27 is closed to form a full circle to close the feed inlet. When drilling the arch, the sealing block 22 at the top of the barrel 21 first contacts the arch, and the sealing block 22 moves downward after being squeezed. The push rod 24 pushes the wave protrusion 32 and then drives the driving disk 28 to rotate, driving the movement of the blade 27 and stretching the return spring 34, so that the blade 27 moves and hides between the driving disk 28 and the mounting plate 26. At this time, the drill rod 20 extends from the barrel 21 to drill the arch. After the drilling is completed, the drill rod 20 shrinks into the barrel 21, and the lifting mechanism drives the mounting frame 12 to move backward. The sealing block 22 extends out, and the stretched return spring 34 begins to reset, driving the driving disk 28 to reset, so that the blade 27 is closed again to form a full circle to close the feed inlet, thereby preventing the waste material in the barrel 21 from spilling out.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
