firstly, the height of the two drilling mechanisms 2 is adjusted by unfolding the folding lifting mechanism 7, the drilling mechanisms 2 are driven by the rotating shafts 9 to rotate and adjust the drilling positions of the drilling mechanisms 2, then the drilling mechanisms 2 are driven by the lead screw driving mechanism of the linear feeding device 11 to advance to send the drill bit to the working position, and finally the drill bit is driven to work by starting the drill bit driving motor of the drilling mechanisms 2. When the automatic drilling machine works, the drilling mechanism 2 is abutted to a working face by using the automatic propelling mechanism, the drilling mechanism 2 and the mounting seat 12-4 stop moving, the screw nut 11-2 extrudes the power spring 12-3, when the screw nut 11-2 drives the linkage rod 12-2 to move to a preset stop position, the linkage rod 12-2 is contacted with the on-off switch 12-1, the on-off switch 12-1 is started, a signal is transmitted to the control system 4, and the control system 4 controls the screw driving mechanism to stop acting through the hydraulic system 3. The elastic force of the power spring 12-3 is used for driving the drilling mechanism to move forwards. When the power spring 12-3 rebounds to drive the screw rod nut 11-2 and the linkage rod 12-2 to move back to the preset starting position, the on-off switch 12-1 is closed, a signal is sent to the control system, and the control system 4 starts the screw rod driving mechanism through the hydraulic system 3 so as to drive the drilling mechanism to continue to advance. In the working process of the drilling mechanism, the expansion amount of the power spring is continuously detected through the sensing device, so that the screw rod driving mechanism is controlled to start or stop, the automatic propulsion of the drilling mechanism 2 is realized by utilizing the elasticity of the power spring, the drill bit of the drilling mechanism 2 is protected, and the service life of the drill bit is prolonged.

When the drilling mechanism 2 tunnels to a set depth, the first limiting rod 13-2 is in contact with the working surface and stops moving; and the screw rod driving mechanism still drives the mounting seat and the first limit switch 13-1 to move forwards, when the first limit rod 13-2 is contacted with the first limit switch 13-1, the first limit device is started, the control system controls the screw rod driving mechanism to stop moving forwards according to the received first limit switch signal, and adjusts the screw rod driving mechanism to drive the drilling mechanism to return to a certain position and then stop, until the rotating shaft 9 rotates to adjust the next position of the drilling mechanism, the control system 4 restarts the screw rod driving mechanism and the drilling mechanism 2.
