[0035] Need to explain: when the single roll 305 moves away from the direction of the roller 2, the single roll 305 rotates by the round plate 310 in one direction, and when the single roll 305 moves to the direction of the roller 2, it is fixed, which can push the scattered asphalt aggregate to the both sides of the asphalt main body.

[0036] Embodiment two: as a specific embodiment of the present application, the surface of the round plate 310 is provided with a plurality of circumferentially distributed chutes 3101, both ends of the single roll 305 are fixed with sliding blocks 3051, the sliding blocks 3051 are slidably installed on the surface of the round plate 310 through the chutes 3101, the inner wall of the single roll 305 is fixed with a circular wheel 3052, the surface of the rotating sleeve 311 is fixed with a plurality of fixed blocks I 3111 corresponding to the number of the circular wheel 3052; the rotating sleeve 311 is sleeved with a rotatable threaded roller 313 inside, the end of the moving rod 312 is rotatably connected with a rotating block II 3131, the moving rod 312 is internally provided with an elastic telescopic telescopic block 3121, there is a gap between the rotating block II 3131 and the telescopic block 3121, the rotating block II 3131 penetrates the threaded groove on the surface of the threaded roller 313; the installation ring 306 is provided with a slot I 3061 near the position of the rotating sleeve 311, the end of the rotating sleeve 311 close to the installation ring 306 is fixed with a fixed block II 3114, the fixed block II 3114 is inserted into the corresponding slot I 3061; the surface of the rotating sleeve 311 in contact with the round plate 310 is provided with a plurality of slots II 3113, the slots II 3113 are circumferentially distributed, the round plate 310 is internally provided with an elastic telescopic block 3102, the two sides of the slot II 3113 are slidably connected with clamping blocks 3112, the surface of the clamping block 3112 is arc-shaped structure, the block 3102 is inserted into the corresponding slot II 3113 and clamped and fixed by the clamping block 3112.

[0037] When one end of the rotating block I 308 and the moving rod 312 move inside the rotating sleeve 311, the rotating block II 3131 penetrates the spiral groove on the surface of the threaded roller 313, and when the moving rod 312 moves, the rotating block II 3131 moves along the spiral groove on the surface of the threaded roller 313 in the direction of the moving rod 312, which can make the threaded roller 313 rotate, the spiral groove of the other end of the threaded roller 313 is oppositely arranged, when the threaded roller 313 rotates, the other end of the spiral groove drives the other end of the moving rod 312 inside the rotating sleeve 311 to move relatively, which can balance the moving gravity of the single roll 305 when adjusting the diameter of the single roll 305;

[0038] Please refer to Figure 8When the single roller 305 moves away from the drum 2, the arc surface of the fixed block II 3114 contacts the elastic block inside the mounting ring 306, and when the fixed block II 3114 contacts the elastic block, the elastic block shrinks to the inside of the mounting ring 306. When the single roller 305 moves towards the drum 2, the flat surface of the fixed block II 3114 contacts the elastic block, and the rotation of the single roller 305 is stopped by the blocking of the elastic block, so that the single roller 305 can only rotate in one direction.

[0039] In operation, first, the moving rod 312 is pushed to move inside the threaded roller 313 and the rotating sleeve 311 by the rotating block I 308, so that the telescopic block 3121 moves along the inner wall of the top of the rotating sleeve 311 and penetrates the slot in the top of the rotating sleeve 311. Then, the rotating block I 308 is rotated in the opposite direction, the telescopic block 3121 is located in the slot in the top of the rotating sleeve 311, and the rotating sleeve 311 is rotated in the opposite direction with the rotating block I 308, so that the fixed block I 3111 abuts against the surface of the circular wheel 3052. Then, the two ends of the single roller 305 slide in the sliding slot 3101 on the surface of the circular plate 310 through the sliding block 3051 to increase the diameter of the single roller 305. When the top of the fixed block I 3111 is close to the circular wheel 3052, the diameter of the single roller 305 can be expanded to the maximum, please refer to Figure 7 When the rotating sleeve 311 is rotated to the desired angle, the plug 3102 is inserted into the corresponding slot II 3113, so that the angle of rotation of the rotating sleeve 311 can be fixed, and the diameter of the single roller 305 adjusted in this way is fixed. When the fixed block I 3111 contacts the circular wheel 3052, the diameter of the single roller 305 is increased. The contact between the fixed block I 3111 and the circular wheel 3052 causes the circular wheel 3052 to rotate in the forward direction, and the engagement between the circular wheel 3052 and the extension piece II 316 pushes the extension piece II 316 to move outwardly of the single roller 305. When the extension piece II 316 moves outwardly of the single roller 305, one side engages the sliding block 3051 and simultaneously drives the extension piece I 315 to move to the other side of the single roller 305. At this time, the directions of movement of the extension piece I 315 and the extension piece II 316 are opposite to each other, so as to increase the circumference of the single roller 305. This can make the single roller 305 increase in diameter while reducing the gap between each single roller 305, so as to avoid the occurrence of ripples and the storage of asphalt particles in the gap when the two sides of the road surface are extruded, and make the two sides of the road surface more flat during extrusion. The diameter of the single roller 305 can be adjusted according to the thickness of the asphalt paving through the arrangement of the single roller 305. If the thickness of the asphalt paving is thicker, the diameter of the single roller 305 is larger. The height of the single roller 305 is higher than the thickness of the two sides of the road surface when the spilled asphalt is pushed towards the drum 2, so that the asphalt on the two sides of the road surface can be consistent with the main body and be on the same straight line;

[0040] A highway engineering asphalt paving method, comprising the following steps:

[0041] Step one: the asphalt is heated by the inside of the machine body 1, then the asphalt is discharged by the discharge box 4, the asphalt particles are paved on the road by the machine body 1, the rolled asphalt is flattened by the roller 2 when the machine body 1 advances, and the flatness of the road is increased;

[0042] Step two: when the roller 2 rotates, the gear I 201 meshes with the gear II 301 and rotates in the same direction with the roller 2, drives the spiral roller 302 to rotate, the connecting shaft 307 is clamped on the surface of the spiral roller 302, the spiral roller 302 drives the connecting shaft 307 to move back and forth at the end of the material arranging mechanism 3, and at the same time, the single-turn roller 305 rotates on the road in one direction;

[0043] Step three: when the single-turn roller 305 moves towards the machine body 1, the single-turn roller 305 stops rotating, and the single-turn roller 305 that stops rotating contacts the ground and produces friction when advancing towards the machine body 1, pushes the spilled asphalt on both sides of the road towards the direction of the roller 2, and squeezes the asphalt by the single-turn roller 305, so that the spilled asphalt is bonded with the edge of the asphalt road and consistent with the main body.
