Technical Field
[0001] This utility model relates to the field of road construction technology, and specifically to an asphalt paving device for road construction. Background Technology
[0002] Asphalt pavement refers to various types of road surfaces constructed by incorporating road-grade asphalt into mineral materials. Asphalt binders enhance the ability of paving aggregates to resist damage from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable surface. Therefore, asphalt pavement is one of the most widely used high-grade road surfaces in road construction. Asphalt pavement pavers are auxiliary devices used in the asphalt pavement process for storing and spreading asphalt, and they are widely used in the field of road construction technology.
[0003] Existing asphalt paving equipment stores asphalt in a hopper and discharges it through a discharge port at the bottom of the hopper, then uses a compaction roller for paving. However, the discharge port structure of the current hopper is simple, and the discharged asphalt is not uniform enough, which affects subsequent paving operations. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an asphalt paving device for road construction, in which asphalt can first enter into a storage tank, and the asphalt can be discharged in equal amounts through the storage tank, and the discharged asphalt can be in a continuous row, so as to solve the problems mentioned in the background art.
[0005] This utility model is achieved through the following technical solution: an asphalt paving device for road construction, comprising a storage hopper, a conveying roller, a flattening roller, and a pressure plate. One end of the storage hopper is open, and the other end has an inwardly narrowed, ring-shaped mounting section. The conveying roller is located inside the mounting section. The end of the mounting section away from the storage hopper has a discharge port. Multiple storage grooves are distributed in a ring structure on the outer surface of the conveying roller. A vibrating assembly for providing vibration to the conveying roller is installed on the side of the mounting section. The pressure plate is installed on one side of the storage hopper. The flattening roller is located between the storage hoppers. The flattening roller and the pressure plate are connected by a bracket.
[0006] As a preferred technical solution, the vibrating assembly includes a vibrating rod and multiple transmission rods. The center of the conveying pipe is provided with an axially open insertion hole. One side of the mounting part is provided with a shaft hole facing the insertion hole.

The multiple transmission rods are mounted on the rod body in a ring structure. The outer side of the transmission rods is in contact with the inner wall of the insertion hole.
[0007] As a preferred technical solution, the pressure plate is arranged in an "L" shape. Multiple reinforcing plates are installed at the bend of the pressure plate. Multiple positioning grooves are provided on the side of the pressure plate facing the storage hopper. Positioning strips are slidably installed in each positioning groove. One side of each positioning strip is installed on the storage hopper. Multiple first screw holes are provided on each positioning strip. Second screw holes are provided on the outer side of the pressure plate opposite to the positioning grooves. Fixing screws are threaded into each of the second screw holes.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an asphalt paving device for road construction, comprising a storage hopper 1, a conveying roller 8, a flattening roller 4, and a pressure plate 5. The storage hopper 1 has an open end and an inwardly tapered mounting section 2 with a ring-shaped cross-section. The conveying roller 8 is located inside the mounting section 2. The end of the mounting section 2 away from the storage hopper 1 has a discharge port. Multiple storage grooves 9 are distributed in a ring shape on the outer surface of the conveying roller 8. A vibrating assembly for providing vibration to the conveying roller 8 is installed on the side of the mounting section 2. The pressure plate 5 is installed on one side of the storage hopper 1. The flattening roller 4 is located between the storage hopper 1 and the pressure plate 5, and the flattening roller 4 is connected to the pressure plate 5 by a bracket.
[0022] In this embodiment, the vibrating assembly includes a vibrating rod 13 and multiple transmission rods. The center of the conveying pipe is provided with an axially open insertion hole 16. One side of the mounting part 2 is provided with a shaft hole facing the insertion hole. The main body of the vibrating rod 13 is mounted on the mounting part 2. The rod body of the vibrating rod 13 passes through the shaft hole and is inserted into the insertion hole 16. Multiple transmission rods are mounted on the rod body in a ring structure. The outer side of the transmission rods is in contact with the inner wall surface of the insertion hole 16.
[0023] In this embodiment, the pressure plate 5 is arranged in an "L" shape. Multiple reinforcing plates are installed at the bend of the pressure plate 5. Multiple positioning grooves 14 are provided on the side of the pressure plate 5 facing the storage hopper 1. Positioning strips 10 are slidably installed in each positioning groove 14. One side of each positioning strip 10 is installed on the storage hopper 1. Multiple first screw holes 11 are provided on each positioning strip 10. Second screw holes are provided on the outer side of the pressure plate 5 opposite to the positioning grooves 14. Fixing screws 12 are threaded into each second screw hole. One end of each fixing screw 12 is threaded into the corresponding first screw hole 11. The pressure plate can move up and down along the positioning strips to adjust the thickness of the asphalt when pressing. The movement of the pressure plate synchronously drives the pressing roller, so that the two can be adjusted synchronously. After adjustment, the moving pressure plate and pressing roller can be fixed by the fixing screws.
[0024] In this embodiment, crossbeams 7 connected to vehicles are installed on both sides of the storage hopper 1. The crossbeams can be installed on the vehicle, thereby driving the movement of this device.
[0025] In this embodiment, a vibrator 6 is installed on the surface of one side of the pressure plate 5.
[0026] In this embodiment, a geared motor 3 is installed on the side of the mounting part 2 away from the vibration component. The shaft of the geared motor 3 passes through the mounting part 2 and is fixedly connected to the feed roller 8.
[0027] During use, asphalt is poured into the storage hopper. The asphalt flows into the storage tank due to its own flow energy, and the vibrator and geared motor are started simultaneously. The vibration energy generated by the vibrator acts on the conveying roller through the transmission plate, allowing the asphalt to enter more fully. The start of the geared motor drives the rotation of the conveying roller. After the storage tank containing asphalt rotates to the bottom, it can be discharged from the outlet. Due to the vibration on the conveying roller, the asphalt can be shaken off more fully, and the discharged asphalt can be in a continuous line. As the storage hopper moves, it can drive the flattening roller and the pressure plate. The flattening roller can flatten the asphalt, and the asphalt on the platform enters the bottom of the pressure plate. Through the vibration of the vibrator and the squeezing of the pressure plate, a secondary flattening operation is performed, which increases the quality of paving.
[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
