When stones are guided to the crushing cavity 1, a worker guides stones to the material receiving groove 32 through the material inlet 2, a large amount of stones are guided to the material receiving groove 32 and then impact the swing arms 333, the two swing arms 333 are stressed to movably expand towards two sides on the rotating shaft, the guide plate 35 is pulled by the two swing arms 333 to enlarge the inner guide opening, the stones in the material receiving groove 32 can be quickly guided to the inside of the crushing cavity 1, after the swing arms 333 are impacted by the stones, the elastic pads 343 on the two swing arms 333 directly receive the impact force of the stone guiding and are sunken inwards, the elastic pads 343 are stressed to disperse the pressure to the air bags 344 and the adjusting pieces 345, the air bags 344 and the adjusting pieces 345 are retracted inwards after being stressed, the elastic pieces c4 and the air cushions c2 receive the pressure of the elastic pads 343, the elastic pieces c4 and the air cushions c2 are retracted inwards at the same time, the 36c 57 is stretched outwards after being stressed and is contacted with the inner wall of the movable pressing block c1 to generate friction resistance at one end, the position of the air cushion c2 is limited, the air cushion c2 is prevented from being pressed and expanded outwards, the air in the air bag 344 contains sodium azide substances, after the air bag 344 is pressed, the sodium azide substances in the air bag 344 can be rapidly decomposed into nitrogen to generate elasticity, the pressed air bag 344 is rapidly ejected upwards, after the air bag 344 is ejected, the elastic plate 342 is stressed to limit the two adjusting pieces 345 to rebound upwards, the adjusting pieces 345 are pulled by the air bag 344, the elastic pieces c4 and the air cushion c2 can be matched to rapidly push the adjusting pieces 345 upwards, so that the two adjusting pieces 345 can be matched with the air bag 344 to push the pressed elastic cushion 343 upwards, the impact force of stone can be effectively reduced, the stone cannot directly impact the inner wall of the machine body 6, the inner wall of the machine body 6 is protected, and the impact force on the machine body 6 is effectively reduced.

The swing arm 333 is impacted by stone and expands outwards, the pressure buffering piece 347 movably impacts the top of the clamping plate 314 along with the swing arm 333, the clamping plate 314 is stressed and then guides extrusion force to the rebound piece 313, the rebound piece 313 is impacted by the impact force of the swing arm 333, the rebound piece 313 is in a symmetrical shaft shape with a convex top and a concave side, the impact force of the swing arm 333 can be uniformly dispersed to each position inside the rebound piece 313, so that the rebound piece 313 cannot be locally stressed, the bottom of the rebound piece 313 can be in contact friction with the clamping plate 314 after being stressed and retracted, the rebound piece 313 is protected by the friction resisting sheet 311, the bottom of the rebound piece 313 is prevented from being directly contacted with the clamping plate 314 to cause friction damage, the contraction piece 152 is pressed downwards after being stressed by the rebound piece 313, the triangular supports 153 are in a triangular structure, the contraction piece 152 can be effectively supported and pressed, the contraction piece 152 is prevented from being deformed due to being pressed, d1 on the two triangular supports 153 are fixed on two sides of the contraction piece 152, the contracting part 152 retracts inwards under the pressure, the connecting rod d1 retracts along with the contracting part 152 to move, the connecting rod d1 drives the two opening and closing blocks d2 to move in an opening and closing mode, the two opening and closing blocks d2 are closed inwards, the two extrusion balloons d4 are extruded by the two opening and closing blocks d2, gas inside the extrusion balloons d4 is converged together to extrude the resisting strip d5, the resisting strip and the extrusion balloons d4 rebound upwards after being pressed together, the opening and closing blocks d2 and the connecting rod d1 are driven by resilience force of the extrusion balloons d4 to stretch the contracting part 152 outwards, the rebounding part 313 can reset quickly after being pressed, the swing arm 333 is ejected upwards to move circularly, the flow guide opening inside the flow guide plate 35 is reduced, the flow guide speed of stone is effectively controlled, the stone is prevented from being completely conveyed to the crushing cavity 1, and the crushing efficiency of the stone is improved.

In conclusion, by arranging the anti-collision device, after the swing arm is impacted by stone, the elastic cushion is stressed to disperse pressure to the air bag and the adjusting pieces, the air bag is compressed to decompose nitrogen through sodium azide in gas to generate elasticity, the compressed air bag and the two adjusting pieces rebound upwards, the two adjusting pieces can be matched with the air bag to push the compressed elastic cushion upwards, the impact force of the stone can be effectively reduced, the stone cannot directly impact the inner wall of a machine body, the swing arm can expand outwards to impact the clamping plate after being impacted by the stone, the rebounding piece can uniformly disperse the impact force to each position inside the rebounding piece after being impacted by the swing arm, the contracting piece can press downwards after being stressed by the rebounding piece, the connecting rod can drive the two opening and closing blocks to move along with the contracting piece, the two opening and closing blocks are closed inwards, and the gas inside the extrusion balloon can be gathered together to extrude the strip, can upwards kick-back after the compression degree together of resistance strip and extrusion balloon for the rebound spare can reset fast after the compression, upwards ejecting the activity of carrying out the circulation with the swing arm, improves the crushing efficiency of building stones.
