[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials into mineral materials. The asphalt binder improves the ability of the paving aggregate to resist damage from traffic and natural factors, making the road surface smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction.

[0028] The reciprocating screw 43 passes through the bottom plate 1, and the scraper 44 is located directly below the bottom plate 1. This design is beneficial for driving the brush plate 45 to brush the asphalt when the scraper 44 rotates clockwise.

[0029] A spraying device 5 is provided on the top of the base plate 1, and the spraying device 5 includes a reciprocating wire sleeve 51, which is threadedly connected to the circumferential surface of the reciprocating screw rod 43, and the circumferential surface of the reciprocating wire sleeve 51 is fixedly connected to a push rod 52, and the side of the push rod 52 is fixedly connected to a force-bearing rod 53. The top of the base plate 1 is fixedly connected to a material storage box 54, and the inner wall of the material storage box 54 is slidably connected to a piston 55. This design is beneficial for driving the push rod 52 to perform reciprocating linear motion when the reciprocating wire sleeve 51 is forced to perform reciprocating linear motion.

[0030] The bottom of the storage box 54 is penetrated by a discharge port 56, the bottom of the bottom plate 1 is fixedly connected to a nozzle 57, and the side of the storage box 54 is provided with a feed valve 58. This design is beneficial when the piston 55 is forced to slide on the inner wall of the storage box 54, so that the inside of the storage box 54 is squeezed.

[0031] The force rod 53 is set to be L-shaped, and the force rod 53 is fixedly connected to the top of the piston 55. The force rod 53 passes through the top of the storage box 54.

After the asphalt material is sprayed out, the paving device 4 can lay the sprayed asphalt material, reducing the working time of the staff and playing an auxiliary role in the paving device 4.
