[0020] S2, rotating the supporting rod to move it outward, then placing the rolled wire mesh in the rectangular frame, then rotating the supporting rod to move inward, placing the rolled wire mesh in the rectangular frame, and laying it outward;

[0021] S3. One end is fixed. As the device moves, the wire mesh is laid. At the same time, the staff mixes the asphalt raw materials, self-healing capsules and anti-cracking agent. After mixing, the materials are unloaded onto the transmission equipment body, and then transported to the ground through the transmission equipment body.

When the lifting rod is separated from the convex rod, the hammer rod moves downward under the action of the second spring, hammers the pin downward, nails the pin to the bottom surface, and presses down the wire mesh to prevent it from bulging and warping.

[0023] Beneficial effects of the present invention:

[0024] 1. Place the rolled wire mesh in a rectangular frame and lay it outward. At the same time, the staff will mix the asphalt raw materials, self-healing capsules and anti-cracking agent. After mixing, unload the materials onto the transmission equipment body, and transport them to the ground through the transmission equipment body. Start the electric roller to drive the spiral blades to rotate. As the device moves as a whole, the concentrated asphalt raw materials in the middle are transported to both sides through the spiral blades, and at the same time, they are preliminarily compacted by the pressure roller to complete the asphalt paving of the road surface. The operation is simple and convenient, which improves work efficiency.

[0025] 2.

At the same time, when the moving rod moves to the right, it drives the hammer rod to move upward, and then the hammer rod moves downward under the action of the second spring, hammering the pin downward, nailing the pin to the bottom surface, and pressing down the wire mesh to prevent it from bulging and warping.

10. The active road crack prevention structure according to claim 8, characterized in that: The specific steps include: S1, bolts are connected to the external vehicle body through the connection holes (104); S2, rotating the supporting rod (302) to move it outward, and then placing the rolled wire mesh in the rectangular frame (301), and then rotating the supporting rod (302) to move it inward, placing the rolled wire mesh in the rectangular frame (301), and laying it outward; S3, one end is fixed, and as the device moves, the wire mesh is laid accordingly, and at the same time, the staff mixes the asphalt raw material, the self-healing capsule and the anti-cracking agent. After the mixing is completed, the material is unloaded onto the transmission device body (201), and is transported to the ground through the transmission device body (201). The electric roller (203c) is started to drive the spiral blade (203d) to rotate. As the device as a whole moves, the concentrated middle asphalt raw material is transported to both sides through the spiral blade (203d), and at the same time, it is preliminarily compacted by the pressure roller (203e); S4, the transmission device body (201) is started, driving the gear (309b) to rotate, driving the toothed belt (309c) to move, when the first protrusion (309d) contacts the pull rod (309e), pulling the pull rod (309e) to move leftward, driving the day frame (303a) to move leftward, compressing the first spring (303c), at this time, the second protrusion (309f) contacts the third protrusion (309g), pushing the moving rod (304d) to move rightward, driving the elastic connecting rod (304e) to move rightward, driving the round rod (303c) to move leftward. 05f) moves to the right, and then the round rod (305f) moves to one side along the Y-shaped opening (305d) and moves to the end of the Y-shaped opening (305d). Then, under the elastic action of the elastic connecting rod (304e), the rectangular plate (305a) is driven to deviate to one side by one end, and at the same time, the magnetic block (305c) away from the deviated side is adsorbed on the connecting block (305b). Then, after the elastic connecting rod (304e) loses the force acting to the right, the elastic connecting rod (304e) drives the elastic connecting rod ( The round rod (305f) is reset to the left, and the round rod (305d) is reset along the Y-shaped opening (305d). At the same time, the elastic connecting rod (304e) is reset to the center under the action of the round rod (305f) under the action of the guide rod (305e), so that it moves to the other side of the Y-shaped opening (305d) when it moves to the right next time. This reciprocating process transports the pin (308) that falls into the rectangular opening (304b) to both sides. At the same time, when the moving rod (304d) moves to the right, it drives the gear rod (309h) to move to the right, so that The transmission wheel (309i) rotates, driving the rotating rod (306f) to rotate and driving the lifting rod (306g) to rotate. When the lifting rod (306g) contacts the protruding rod (306e), it is lifted upward, driving the hammer rod (306b) to move upward. When the lifting rod (306g) is separated from the protruding rod (306e), the hammer rod (306b) moves downward under the action of the second spring (306d), hammering the pin (308) downward, nailing the pin (308) to the bottom surface, pressing down the wire mesh to prevent it from bulging and warping.
