Description

Technical Field

[0001] This application relates to the field of road engineering construction and maintenance technology, specifically to an adjustable asphalt pavement cold recycling double-layer continuous paving equipment. Background Technology

[0002] The cold recycling double-layer paving equipment for asphalt pavement aims to achieve high-efficiency road maintenance by simultaneously completing the milling of the old pavement, material recycling, and paving of the upper and lower layers. It can significantly shorten the construction cycle, reduce traffic impact, avoid the waste of old materials, reduce the consumption of new materials, save costs, and be environmentally friendly. Through double-layer paving, it ensures structural integrity, improves pavement performance, and provides an efficient and low-carbon technical solution for asphalt pavement maintenance, promoting the green and intelligent development of road maintenance.

[0003] When operating a cold recycling double-layer continuous asphalt pavement paving machine, the old pavement is first milled and crushed, then mixed with water and recycling agents in a mixing bin to form recycled material. Subsequently, the equipment lays the recycled material in layers, with the lower layer laid first and the upper layer following closely behind, and the layers are simultaneously compacted. It is suitable for major repairs and reconstructions of asphalt pavements on national and provincial highways and urban roads, especially for sections with high traffic volume and tight schedules. It can operate at ambient temperatures, reducing energy consumption, achieving the recycling of old materials, and improving construction efficiency and pavement quality.

[0004] In existing technologies, some cold recycling double-layer continuous paving equipment for asphalt pavement typically lays the processed material directly onto the road. However, this method is difficult to adapt to different road widths, leading to material waste by extending beyond the road edge or insufficient width requiring manual replenishment or re-application of the equipment to cover the edges, thus increasing construction steps and time costs. Therefore, an adjustable cold recycling double-layer continuous paving equipment for asphalt pavement is proposed. Utility Model Content

[0030] Two hydraulic cylinders 42 are fixedly connected to the bottom of the square plate 41. The hydraulic cylinders 42 drive the fixed plate 43 and the crusher 44 to move up and down through telescopic movement, so as to start and stop the milling operation. The driving end of the hydraulic cylinder 42 is fixedly connected to the fixed plate 43. The fixed plate 43 is used to install the crusher 44. It moves up and down with the hydraulic cylinder 42 to adjust the working position of the crusher 44. The inner wall of the laying box 1 is fixedly connected to the baffle 9. The baffle 9 is used to separate the processing area and the mixing area, so that the material is processed in sequence according to the process. The crusher 44 is installed at the bottom of the fixed plate 43. After the crusher 44 is started, it mills the ground and breaks the old road surface into residue. The inner wall of the laying box 1 is installed with the elevator 45. The elevator 45 transports the milled road residue to the jaw crusher 5 to realize the continuous conveying of materials. The front side of the laying box 1 is fixedly connected to the body 10. The body 10 serves as the main frame of the equipment, integrating and installing various mechanisms and components to ensure the stability of the overall structure of the equipment.

The front side of the laying box 1 is fixed with an organic body 10, which serves as the main frame of the equipment and integrates and installs various mechanical components to ensure the stability of the overall structure.

[0031] Working principle: After the processing of the material in the processing area inside the baffle 9 is completed, the material is discharged through the discharge port 26. At this time, the distribution motor 22 starts and drives the screw feeder 27 to rotate. The rotation of the screw feeder 27 causes the material inside to be distributed. When it is necessary to discharge according to different laying sizes, the adjusting motor 252 starts and drives the adjusting plate 251 to move to both sides or move towards the middle. At this time, the movement of the adjusting plate 251 causes the adjusting block 253 to move inside the fixed block 21, thereby controlling the width of the material laying. When cold recycling of the road is required, hydraulic cylinder 42 is activated to lower the fixed plate 43 and crusher 44. Then, crusher 44 starts milling the ground. Next, elevator 45 starts, conveying the road debris milled by crusher 44 into jaw crusher 5. Jaw crusher 5 then breaks up the road debris. Then, motor 32 starts, driving rotating disc 33 to rotate. The rotation of rotating disc 33 causes rotating column 35 to move in a circular motion. Then, rotating column 35... The motion drives the connecting shaft 34 and the connecting rod 36 to move. At this time, the movement of the connecting rod 36 causes the connecting plate 38 and the vibrating net 37 to vibrate on the inner wall of the laying box 1. At this time, the vibrating net 37 screens the crushed stone slag onto the inner wall of the vibrating net 37. At this time, the conveyor 6 transports the screened residue to the stirring zone separated by the baffle 9. At this time, the liquid and processing agent required for processing are added to the stirring zone separated by the drive motor 8 through the feeding port 7. Then, the stirring motor 23 starts and drives the stirring rod 24 to rotate to stir the internal laying material.
