Firstly, the heights of the two drilling mechanisms 2 are unfolded and adjusted through the folding lifting mechanism 7, the drilling mechanisms 2 are driven by the rotating shafts 9 to rotate so as to adjust the drilling positions of the drilling mechanisms 2, then the drilling mechanisms 2 are driven by the screw rod driving mechanism of the linear feeding device 11 to advance so as to send a drill bit to a 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 automatic propulsion mechanism is utilized, the drilling mechanism 2 is propped against a working surface, 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 in contact with the on-off switch 12-1, the on-off switch 12-1 is started, signals are transmitted to the control system 4, and the control system 4 controls the screw driving mechanism to stop moving 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 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 driving mechanism through the hydraulic system 3, so that the drilling mechanism is driven to move forward continuously. In the working process of the drilling mechanism, the stretching 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 is driven to a set depth, the first limiting rod 13-2 is contacted with the working surface to stop moving, the lead screw driving mechanism still drives the mounting seat and the first limiting switch 13-1 to move forward, when the first limiting rod 13-2 is contacted with the first limiting switch 13-1, the first limiting device is started, the control system controls the lead screw driving mechanism to stop moving forward according to the received first limiting switch signal, and adjusts the lead screw driving mechanism to drive the drilling mechanism to retract to a certain position to stop moving until the rotating shaft 9 rotates to adjust the next position of the drilling mechanism, and then the control system 4 restarts the lead screw driving mechanism and the drilling mechanism 2.
