secondly, tunneling: the device is placed in front of a roadway, a control chip (27) controls a motor four (21) to operate, the motor four (21) operates to drive a fixing column two (20) to rotate, the fixing column two (20) rotates to drive a barrel body one (12) and a barrel body two (15) to rotate, the barrel body two (15) rotates to drive a sharp part (32) to rotate, then the control chip (27) controls a motor two (3) to operate, the motor two (3) operates to drive a main shaft one (30) to rotate, the main shaft one (30) rotates to drive a large gear (22) to rotate, the large gear (22) rotates to drive a small gear (29) meshed with the large gear to rotate, the small gear (29) rotates to drive a forward rotation screw (28) and a reverse rotation screw (31) to rotate, the forward rotation screw (28) and the reverse rotation screw (31) rotate to drive a fixing plate one (5) to slide along the forward rotation screw (28) and the reverse rotation screw (31), and the fixing plate one (5) can drive the barrel body one (12, the control chip (27) controls the cylinder II (8) to stretch, the cylinder II (8) can drive the cylinder I (12) and the cylinder II (15) to lift, the control chip (27) can control the cylinder I (12) and the cylinder II (15) to move randomly in the plane direction under the action of the cylinder I and the cylinder II, then the control chip (27) controls the double-head motor (2) to rotate, the double-head motor (2) rotates to drive the gear I (24) to rotate, the gear I (24) rotates to drive the crawler belt (23) to move forwards for a certain distance, the crawler belt (23) has the function of preventing backward movement, the crawler belt (23) moves forwards to drive the sharp part (32) at the rear end of the rotating cylinder II (15) to drill a coal roadway, when coal enters the cylinder II (15) from the rear end of the cylinder II (15), the coal is firstly ground by the rotating blade barbed wire (17), and small coal particles after ground enter the position of the cylinder II (15) where the barbed wire (16) is located, at the moment, the control chip (27) controls the cylinder III (11) to stretch continuously, the cylinder III (11) stretches to drive the telescopic column (14) to stretch, the telescopic column (14) stretches to drive the barb strip (16) to stretch, the barb strip (16) stretches to sweep the minced small-particle coal to the front of the material baffle plate (13), then the small particles fall into the temporary storage box (18) through the discharge hole (33), and then the small-particle coal is sucked out of the roadway by the fan through the material guide pipe (19) and the hose (34) to be collected;
thirdly, feeding: after a period of time, after the coal in the covered volume of the second cylinder (15) is cleaned, the control chip (27) controls the double-end motor (2) to rotate reversely, so that the second cylinder (15) returns to the front of the roadway wall, then the control chip (27) controls the first fixing plate (5) to slide and the second air cylinder (8) to lift, so that the second cylinder (15) moves to the other position of the roadway wall, the second step is repeated, and the control chip (27) can calculate the minimum tunneling feed path;
fourthly, continuing to advance: after the primary feed of the coal mine tunnel is finished, the crawler belt (23) can continue to advance for a certain distance, and then the tunneling in the second step and the feeding in the third step are repeated to tunnel the tunnel again until the required tunnel length is reached.
