Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-3 The utility model provides a new technical solution: an asphalt concrete paving mechanism, comprising a feeding cylinder 1, on which a uniform paving mechanism is provided, the uniform paving mechanism being used to uniformly spread asphalt or concrete;

[0026] The outer surface of the feeding cylinder 1 is fixedly connected to a mounting plate 13, on which a gear reciprocating swing mechanism is provided. The gear reciprocating swing mechanism is used to drive the paving roller 5 to swing back and forth to evenly spread the asphalt concrete.

[0027] The uniform paving mechanism includes a rotating plate 2, which is rotatably connected to the outer surface of the lower outlet of the feeding cylinder 1, and the lower outlet of the feeding cylinder 1 is fixedly connected to the discharge nozzle 11;

[0028] The outer surface of the rotating plate 2 is fixedly connected to the rotating shaft fixing frame 3, and the rotating shaft 4 is rotatably connected inside the rotating shaft fixing frame 3. The outer surface of the rotating shaft 4 is fixedly sleeved with a paving roller 5, and the outer surfaces on both sides of the rotating shaft fixing frame 3 are bolted to arc-shaped baffles 9.

[0029] Furthermore, the arc-shaped baffle 9 is fitted with the paving roller 5 , and the arc-shaped baffle 9 is used to prevent the asphalt concrete from overflowing from both sides of the paving roller 5 , so that the asphalt concrete can be evenly paved.

[0030] Furthermore, the gear reciprocating swing mechanism includes two small gears 14, which are rotatably connected to the outer surface of the mounting plate 13, and a large gear 16 is rotatably sleeved on the outer surface of the outlet at the lower end of the feeding cylinder 1.

[0031] Furthermore, the large gear 16 is fixedly connected to the rotating plate 2, and the large gear 16 is meshed with the two small gears 14. A gear motor 18 is fixedly connected to the mounting plate 13 by bolts. The output shaft of the gear motor 18 rotates through the lower surface of the mounting plate 13 and is fixedly sleeved with a local gear 15. The local teeth on the local gear 15 are respectively meshed with the two small gears 14.

[0032] Furthermore, both ends of the rotating shaft 4 rotate and pass through the outer surface of the rotating shaft fixing frame 3. A sprocket 6 is fixedly sleeved at one end of the rotating shaft 4. A sprocket motor 8 is fixedly connected with bolts on the upper surface of the rotating shaft fixing frame 3. The outer surface of the output shaft of the sprocket motor 8 is fixedly sleeved with the same sprocket 6. A chain 7 is connected between the two sprockets 6 for transmission.

[0033] Furthermore, fixed frames 12 are fixedly connected to both sides of the feed barrel 1, and movable lifting wheel devices 10 are provided on both fixed frames 12. The movable lifting wheel devices 10 are used to control the movement and paving thickness of the asphalt concrete paving mechanism. A mixing device 17 is fixedly connected to the feed barrel 1, and the mixing device 17 is used to mix asphalt concrete. The mixing device 17 and the movable lifting wheel devices 10 are both existing technologies and will not be described in detail here.

[0034] Furthermore, when in use, a carrier is used to connect with the asphalt concrete paving mechanism and drive it to move forward, and then by starting the feed drum 1, the feed drum 1 conveys the asphalt concrete mixed by the mixing device 17 to the outlet of the discharge nozzle 11. When the asphalt concrete paving mechanism moves, the paving roller 5 will come into contact with the asphalt concrete and roll the asphalt concrete onto the ground to be paved. The mobile lifting wheel device 10 is provided to control the distance between the paving roller 5 and the ground, thereby controlling the paving thickness. By starting the gear motor 18, the gear motor 18 drives a small gear 14 to rotate a certain angle through the meshing of the local teeth of the local gear 15 on its output shaft with a small gear 14. When the small gear 14 rotates, it can drive the large gear 16 to rotate a certain angle at the same time. When the large gear 16 rotates, it will drive the rotating shaft fixing frame 3 and the paving roller 5 thereon to rotate together through the rotating plate 2.

The flatness of the road surface is improved, and the driving comfort and safety of the road surface are also improved, ensuring that the asphalt mixture is evenly distributed in various parts of the road surface, avoiding local weak areas or overly thick raised areas, which helps to reduce damage to the road surface and the frequency of repairs, thereby extending the service life of the road surface.

[0035] Furthermore, when the gear reciprocating swing mechanism drives the paving roller 5 to swing back and forth about the axis of the large gear 16, the asphalt concrete can be laid following the rolling direction of the paving roller 5. At the same time, the arc-shaped baffle 9 is also fitted with the paving roller 5, so that the asphalt concrete will not overflow from both sides of the paving roller 5, thereby avoiding waste of materials. This not only helps to save construction costs, but also is beneficial to environmental protection and sustainable development, and improves the quality of the construction environment.

[0036] Working principle: By using a carrier to connect with the asphalt concrete paving mechanism and drive it to move forward, and then by starting the feed drum 1, the feed drum 1 conveys the asphalt concrete mixed by the mixing equipment 17 to the outlet of the discharge nozzle 11. When the asphalt concrete paving mechanism moves, the paving roller 5 will contact the asphalt concrete and roll the asphalt concrete on the ground to be paved. The mobile lifting wheel device 10 is provided to control the distance between the paving roller 5 and the ground, thereby controlling the paving thickness. By starting the gear motor 18, the gear motor 18 drives a small gear 14 to rotate a certain angle through the engagement of the local teeth of the local gear 15 on its output shaft with a small gear 14. When the small gear 14 rotates, it can drive the large gear 16 to rotate a certain angle at the same time. When the large gear 16 rotates, it will drive the rotating shaft fixing frame 3 and the paving roller 5 thereon to rotate together through the rotating plate 2. When the local teeth on the local gear 15 engage with another small gear 14, it can drive the large gear 16 to rotate in the opposite direction by a certain angle. Finally, the paving roller 5 can swing back and forth slightly with the axis of the large gear 16 as the center of the circle while rotating itself, thereby evenly laying the asphalt concrete on the ground.
