After the two first fixing frames 213 are installed, an operator rotates the threaded rod 209, the threaded rod 209 rotates to drive the guide rod 210 to move outwards, the guide rod 210 drives the third rotating rod 212 to move outwards, so that the third rotating rod 212 and the second sliding block 211 rotate, meanwhile, the second sliding block 211 slides correspondingly on the first fixing frames 213, the lower part of the first fixing frames 213 moves outwards, namely the first fixing frames 213 and the fixing frames 203 rotate around the first rotating rod 204, so that the first fixing frames 213 incline, the first fixing frames 213 on the other side of the heading machine 1 incline in the same way, and parts on the inclined first fixing frames 213 protect the operator and the heading machine 1.
In an initial state, the first sliding plate 503 is in contact with the second sliding plate 504, the first steel wire rope 306, the second steel wire rope 310 and the third steel wire rope 502 are in a tight state at the moment, when a coal rock block impacts on a net formed by staggering a plurality of first steel wire ropes 306 and second steel wire ropes 310, the first steel wire ropes 306 and the second steel wire ropes 310 are deformed by impact, the coal rock block is intercepted by the first steel wire ropes 306 and the second steel wire ropes 310 at the moment, the deformation of the first steel wire ropes 306 and the second steel wire ropes 310 pulls the sliding rods 304 in contact with the first steel wire ropes 306 and the second steel wire ropes 310 to move inwards, and the sliding rods 304 move inwards to compress the adjacent second springs 305, so that the first steel wire ropes 306 and the second steel wire ropes 310 buffer and intercept the ejection coal rock block.
When the sliding rod 304 moves inwards, the sliding rod 304 drives the first sliding plug 402 connected with the sliding rod 304 to move inwards, at this time, under the action of hydraulic oil in the cylindrical shell 401, the third sliding block 403 keeps relatively static, so that the second sliding plug 404 is separated from the cylindrical hole of the first sliding plug 402, the flow cross section of the hydraulic oil is pressurized, and then the first sliding plug 402 moves to pull the third sliding block 403 and the second sliding plug 404 to move inwards until the coal rock block is intercepted.
Meanwhile, in the deformation process of the first steel wire rope 306, the first steel wire rope 306 drives the two second sliding plates 504 to move inwards through the rectangular blocks on the first steel wire rope, the two second sliding plates 504 move inwards to extrude the adjacent first sliding plates 503, the four first sliding plates 503 are extruded to move outwards, the first sliding plates 503 move outwards to pass through the adjacent fourth sliding blocks 501 to drive the third steel wire rope 502 and the second connecting block 506 to move, the fourth sliding blocks 501 move to compress the adjacent third springs 505, and the first steel wire rope 306, the second steel wire rope 310 and the first connecting block 311 are combined to form a mesh hole which is separated by the three steel wire ropes 502 to be reduced along with the movement of the third steel wire rope 502 and the second connecting block 506, so that the three steel wire ropes 502 can hold and intercept coal rock blocks located at the mesh hole.

After the first steel wire rope 306 and the second steel wire rope 310 finish intercepting the coal rock, under the action of the second spring 305, the sliding rod 304 moves outwards to reset, and under the action of the third spring 505, the fourth sliding block 501 drives parts connected with the fourth sliding block to move reversely and restore to an initial state, so that the third steel wire rope 502 restores to the initial state, and the third steel wire rope 502 releases the clamping of the coal rock.
When the sliding rod 304 moves outwards, the sliding rod 304 pulls the first steel wire rope 306, the second steel wire rope 310 and the third steel wire rope 502 which are in contact with the sliding rod 304, so that the sliding rod is tightened and reset, meanwhile, the sliding rod 304 moves outwards to drive the first sliding plug 402 connected with the sliding rod to move reversely, as the cylindrical shell 401 is filled with hydraulic oil and the arc-shaped surface of the third sliding block 403 acts, when the first sliding plug 402 moves, the third sliding block 403 and the second sliding plug 404 keep relatively static firstly, so that the second sliding plug 404 enters the cylindrical hole of the first sliding plug 402, then the first sliding plug 402 moves to push the third sliding block 403 and the second sliding plug 404 to move continuously, in the process, the flow cross section of the hydraulic oil on the first sliding plug 402 becomes small, and simultaneously, in combination with the resistance of the third sliding block 403, when the first sliding plug 402, the third sliding block 403 and the second sliding plug 404 move, the resistance of the hydraulic oil is increased, so that the sliding rod 304 is slowly reset, namely the first steel wire rope 306, the second steel wire rope 310 and the third steel wire rope 502 are slowly reset, and the intercepted coal rock blocks are prevented from being reversely popped out in the resetting process.
When an emergency occurs, an operator holds the long handle of the second sliding block 211 to lift upwards, the second sliding block 211 moves to drive the third rotating rod 212 to move, so that the third rotating rod 212 is separated from the cylindrical hole of the guide rod 210, and then under the action of the torsion spring 206, the first fixing frame 213, the fixing frame 203 and the first rotating rod 204 drive parts on the first fixing frame to rotate, the first fixing frame 213 rotates to remove shielding of the cab of the heading machine 1, so that the operator can quickly escape from the heading machine 1, and the safety of the operator is ensured.
After the excavation of the tunnel is completed, the operator lifts the long handle of the second sliding block 211 upwards in the same manner, so that the third rotating rod 212 is separated from the cylindrical hole of the guide rod 210, then the operator presses the protruding column 207 and lifts the first fixing frame 213 upwards, so that the first fixing frame 213, the fixing frame 203 and the first rotating rod 204 drive parts thereon to be taken out from the heading machine 1 together, and then the heading machine 1 is disassembled and taken out from the coal mine roadway step by step.
