[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0014] As Figures 1 - 3 shown, a coal mine tunneling device includes a frame 1, on which a docking seat 2, an adjustment motor 3 and a guide shaft 4 are provided. The docking seat 2 is integrally formed and equidistantly connected to both sides of the rear end of the frame 1. The adjustment motor 3 is installed and fixed on the front right side of the top of the frame 1 through screws. The main shaft of the adjustment motor 3 penetrates and extends into the interior of the frame 1 and is installed and fixed with an adjustment screw 5 through screws. The guide shaft 4 is installed and fixed equidistantly on the front left side of the interior of the frame 1 through screws. A transmission shaft sleeve 6 is sleeved on the guide shaft 4. The right side of the transmission shaft sleeve 6 is threadedly connected to the adjustment screw 5. The rear end of the transmission shaft sleeve 6 is integrally formed and connected with a docking plate 7. The rear end of the docking plate 7 is installed and fixed with a power motor 8 through screws. A power shaft 9 is installed and fixed on the main shaft of the power motor 8 through screws. The power shaft 9 is rotatably connected to the interior of the transmission shaft sleeve 6. The front end of the power shaft 9 extends to the outside of the front end of the transmission shaft sleeve 6 and is integrally formed and connected with a transmission plate 10. The front end of the transmission plate 10 is installed and fixed with a tunneling head 11 through screws.

[0015] Specific usage method: Install and fix the frame 1 on the front end of the tunneling vehicle through the docking seat 2. Then, according to the tunneling position, start the adjustment motor 3 to drive the adjustment screw 5 to rotate.
