Description

Technical Field

[0001] This utility model belongs to the technical field of paving devices, specifically a paving device for asphalt concrete surface layer of municipal roads. Background Technology

[0002] Asphalt concrete pavement pavers are small-scale devices used for the repair of localized defects on urban roads. They are lightweight, flexible, and easy to operate. Typically, they consist of a mobile vehicle, a storage tank, a discharge pipe, and a compaction roller. They allow for precise control of the asphalt discharge speed and repair thickness. During the repair process, the compaction roller compacts the pavement, ensuring the repaired area is as smooth as the original surface, improving aesthetics and driving comfort. These devices are widely used for repairing potholes and cracks in small areas of asphalt pavement, such as urban roads, residential roads, and parking lots. They are particularly suitable for rapid repair work on busy roads or in areas with limited space, effectively shortening construction time and minimizing traffic disruption.

[0003] An existing patent (publication number: CN222251616U) discloses an asphalt paving device for municipal road construction. This device allows for continuous adjustment of the airflow direction according to usage needs, thereby increasing the airflow range and blowing dust and soil on the ground away from the asphalt paving location, ensuring clean asphalt paving and improving the quality of asphalt paving. However, the discharge port of this paving device is easily blocked by asphalt concrete, preventing normal material discharge and affecting construction efficiency. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an asphalt concrete pavement device for municipal roads, which effectively solves the problem that the discharge port of the existing paving device is easily blocked by asphalt concrete, resulting in the inability to discharge materials normally and affecting construction efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a municipal road asphalt concrete surface paving device, comprising a main body, four universal wheels rotatably mounted on the bottom of the main body, a support platform fixedly mounted on one side of the top of the main body, a handle fixedly mounted on the top of the main body, a placement tank fixedly mounted on the other side of the top of the main body, a hydraulic cylinder fixedly mounted on one side of the support platform, a pressure roller rotatably mounted on the transmission end of the hydraulic cylinder, a connecting frame fixedly mounted on one side of the main body, a servo motor fixedly mounted on one side of the connecting frame, eight stirring rods provided in the lower part of the interior of the placement tank, a discharge cylinder fixedly mounted in the middle of the bottom of the placement tank, an auger provided inside the discharge cylinder, a protective cylinder fixedly mounted at the bottom of the discharge cylinder, a discharge pipe fixedly mounted on the surface of the discharge cylinder, a transmission component provided at the output end of the servo motor, the transmission component being connected to the auger and the eight stirring rods, and the servo motor outputting power to the auger and the eight stirring rods through the transmission component when it is running.

[0006] Preferably, the transmission assembly includes a lower sprocket, which is fixedly installed at the output end of the servo motor. An upper sprocket is provided above the lower sprocket, and a chain is meshed between the upper and lower sprockets. A rotating shaft is fixedly installed on one side of both the upper and lower sprockets, and the surfaces of the two rotating shafts are rotatably connected to the main body of the device through bearings.

[0007] Preferably, one end of each rotating shaft is fixedly mounted with a driving bevel gear, and one side of each driving bevel gear is meshed with a driven bevel gear. The bottom of the driven bevel gear located at the lower part is rotatably connected to the inner bottom of the protective cylinder through a shaft seat. The top of the driven bevel gear located at the lower part is fixedly connected to the bottom end of the auger. The bottom of the driven bevel gear located at the upper part is fixedly mounted with a shaft rod.

[0008] Preferably, the lower end of the auger surface is rotatably connected to the bottom of the feed cylinder via a rotating sleeve, the upper end of the shaft surface is rotatably connected to the middle of the top of the device body via a bushing, and the lower end of the shaft surface is fixedly connected to eight agitator rods.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator puts asphalt concrete into the placement tank through the feed valve, and then pushes the main body of the device through the handle to make the four universal wheels roll, thereby conveniently pushing the device to the work site; then the operator aligns the discharge pipe with the pit to be repaired, and then starts the servo motor to drive the lower sprocket to rotate. When the lower sprocket rotates, it drives the upper sprocket to rotate through the chain. When the upper and lower sprockets rotate, they both drive the shaft to rotate inside the bearing.

[0010] When both shafts rotate, the driving bevel gear drives the driven bevel gear to rotate. The rotation of the two driven bevel gears drives the auger and shaft to rotate respectively. When the shaft rotates, it drives eight stirring rods to stir the asphalt concrete located at the bottom of the placement tank, allowing it to enter the discharge cylinder more effectively. When the auger rotates, it transports the asphalt concrete through the discharge pipe to the surface layer of the municipal road, preventing blockage during asphalt concrete discharge. Then, the hydraulic cylinder is activated to drive the pressure roller to move down and compact the repair area. This ensures that the discharge port of the paving device will not be blocked by asphalt concrete, thus guaranteeing normal material discharge and improving construction efficiency.

[0021] In use, the operator feeds asphalt concrete into the placement tank 7 through the feed valve 12. Then, the operator pushes the main body 1 of the device using the handle 4, causing the four casters 2 to roll, thus easily moving the device to the work site. The operator then aligns the discharge pipe 13 with the pit to be repaired, and starts the servo motor 9 to drive the transmission component. When the transmission component is running, it drives the auger 11 and eight stirring rods 10 to rotate. The eight stirring rods 10 stir the asphalt concrete at the bottom of the placement tank 7, allowing it to enter the discharge cylinder 23 more effectively. When the auger 11 rotates, it delivers asphalt concrete through the discharge pipe 13 to the surface of the municipal road, preventing blockage during asphalt concrete discharge. Then, the hydraulic cylinder 5 is activated to move the pressure roller 6 down to compact the repair area. This ensures that the discharge port of the paving device is not blocked by asphalt concrete, thus guaranteeing normal material discharge and improving construction efficiency.

[0022] The transmission assembly includes a lower sprocket 14, which is fixedly installed at the output end of the servo motor 9. An upper sprocket 15 is provided above the lower sprocket 14. A chain 16 is meshed between the upper sprocket 15 and the lower sprocket 14. A rotating shaft 17 is fixedly installed on one side of both the upper sprocket 15 and the lower sprocket 14. The surfaces of the two rotating shafts 17 are rotatably connected to the main body 1 of the device through bearings 18.

[0023] The operator starts the servo motor 9 to drive the lower sprocket 14 to rotate. When the lower sprocket 14 rotates, it drives the upper sprocket 15 to rotate through the chain 16. When the upper sprocket 15 and the lower sprocket 14 rotate, they both drive the shaft 17 to rotate inside the bearing 18.

[0024] One end of the rotating shaft 17 is fixedly mounted with a driving bevel gear 19, and one side of the surface of the driving bevel gear 19 is meshed with a driven bevel gear 20. The bottom of the driven bevel gear 20 located at the lower part is rotatably connected to the inner bottom of the protective cylinder 12 through the bearing seat 25. The top of the driven bevel gear 20 located at the lower part is fixedly connected to the bottom end of the auger 11. The bottom of the driven bevel gear 20 located at the upper part is fixedly mounted with a shaft 21.

[0025] The lower end of the surface of the auger 11 is rotatably connected to the bottom of the feed cylinder 23 through the rotating sleeve 24, the upper end of the surface of the shaft 21 is rotatably connected to the middle of the top of the device body 1 through the bushing 22, and the lower end of the surface of the shaft 21 is fixedly connected to the eight stirring rods 10.

[0026] When the two rotating shafts 17 rotate, they drive the driven bevel gears 20 to rotate through the driving bevel gear 19. When the two driven bevel gears 20 rotate, they drive the auger 11 and the shaft 21 to rotate respectively. When the shaft 21 rotates, it drives the eight stirring rods 10 to stir the asphalt concrete located at the bottom of the placement tank 7, so that it can enter the interior of the discharge cylinder 23 better. When the auger 11 rotates, it will transport the asphalt concrete through the discharge pipe 13 to the surface layer of the municipal road, avoiding blockage when the asphalt concrete is discharged.
