[0002] A tunnel is an engineering structure buried underground, representing a form of human utilization of underground space. Tunnels can be categorized into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. During tunnel construction, drilling is required into the tunnel walls for purposes such as blasting, sampling, installing anchor bolts, or other reasons.

Both the first driving member and the second driving member 113 are motors, and the motor of the second driving member 113 drives the second turntable 111 to rotate through a belt and pulley structure.

[0034] The cylinder body of the first hydraulic cylinder 108 is fixed to the first turntable 103, and its output shaft is fixed to the first slider 107. The guide block 109 is fixedly connected to the first slider 107. The second slider 110 is horizontally slidably connected to the guide block 109. Specifically, the second slider 110 moves along the length of the guide block 109. The second turntable 111 is rotatably connected to the second slider 110. The second turntable 111 is a three-rotor chuck, and its jaws are used to fix the drill pipe 114. A protrusion 109a is provided on one side of the guide block 109. The cylinder body of the second hydraulic cylinder 112 is fixed to the protrusion 109a of the guide block 109, and its output shaft is fixed to the second slider 110. The mounting plate 115 is fixedly connected to the guide block 109. The adjusting block 116 is radially slidably connected to the mounting plate 115.

The spray disc 124 has multiple spray holes. The spray elements are inclined.

[0037] Working principle: The first driving component drives the first turntable 103 to rotate. The rotation of the first turntable 103 adjusts the drilling angle of the drill pipe 114, so that the drill pipe 114 can be adjusted 360 degrees. Then, the first hydraulic cylinder 108 drives the first slider 107 to move, thereby adjusting the height of the drill pipe 114. Then, the second driving component 113 drives the second turntable 111 to rotate. The rotation of the second turntable 111 drives the drill pipe 114 to rotate. Then, the second hydraulic cylinder 112 drives the second slider 110 to move. The movement of the second slider 110 drives the drill pipe 114 to drill the tunnel. At the same time, water from the water pipe is delivered to the delivery pipe 123, and then delivered to the spray plate 124 through the delivery pipe 123, thereby achieving the effect of dust reduction. At the same time, when different drill pipes 114 need to be used for drilling, the push plate 122 is pushed. The movement of the push plate 122 drives the connecting column 121 to move, so that the fastening block 119 is separated from the mounting plate 115. Then, the position of the adjusting block 116 is adjusted, the push plate 122 is released, and under the action of the first spring, the fastening block 119 and the mounting plate 115 will abut together and be fixed by friction, thereby adjusting the position of the adjusting block 116. This is suitable for dust removal of drill pipes 114 of different diameters and has better versatility.
