[0002] With the acceleration of urbanization, the scale of urban transportation infrastructure construction continues to expand, and the performance and quality of roads, as a key carrier of transportation, are receiving increasing attention. Among various road paving materials, large-particle-size permeable asphalt mixtures have become an ideal choice for modern urban road construction due to their excellent drainage performance, skid resistance, and noise reduction effect, requiring the use of automated paving equipment during road construction.

[0003] In permeable asphalt mixtures with large aggregate sizes, if the mixing process is monotonous, coarse and fine aggregates may not mix thoroughly, leading to a situation where coarse aggregates accumulate in certain areas while fine aggregates concentrate elsewhere. This results in an uneven pavement structure, affecting the pavement's strength and stability. Utility Model Content

A first motor drives a rotating rod, which in turn drives a mixing plate to stir the materials. The rotating rod also drives a circular plate, which in turn drives a semi-circular block. The semi-circular block abuts against a connecting plate, which in turn drives a sliding rod, which in turn drives a tamper to tamper with the materials. This ensures that the large-particle-size aggregates, asphalt, mineral powder, and additives are thoroughly and evenly mixed, avoiding aggregate segregation and uneven asphalt distribution, and guaranteeing the consistency of the mixture.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an automated paving device for large-particle-size permeable asphalt mixture, comprising: a movable plate 1 serving as the main moving body; a mixing tank 3 fixedly connected to the top right side of the movable plate 1; a first motor 4 fixedly connected to the front end of the mixing tank 3; a drive end of the first motor 4 penetrating the mixing tank 3 and fixedly connected to a rotating rod 5; multiple mixing plates 6 fixedly connected to the outer wall of the rotating rod 5; a circular plate 7 fixedly connected to the rear end of the rotating rod 5; multiple semi-circular blocks 8 fixedly connected to the front end of the circular plate 7; and multiple sliding rods 9 slidably connected to the inner wall of the mixing tank 3, with the rear ends of each sliding rod 9 fixedly connected to... There is a connecting plate 10, and springs 11 are provided between the connecting plate 10 and the inner wall of the mixing tank 3. A pressing component is provided on the right side of the top of the moving plate 1. One end of each spring 11 is connected to the connecting plate 10, and the other end of each spring 11 is connected to the inner wall of the mixing tank 3. Multiple poking rods 12 are fixedly connected to the outer wall of the sliding rod 9. The outer wall of the rotating rod 5 is rotatably connected to the inner wall of the mixing tank 3. The top of the mixing tank 3 is fixedly connected to the feeding port 13, and the bottom of the mixing tank 3 is fixedly connected to the discharging port 14. A control valve 2 is provided on the outer wall of the discharging port 14. A through hole is provided on the inner wall of the moving plate 1 corresponding to the discharging port 14.

[0024] Specifically, after the mixed materials are fed into the mixing tank 3 through the feeding port 13, the first motor 4 is immediately started. The drive end of the first motor 4 rotates, causing the connected rotating rod 5 to rotate synchronously. During the rotation of the rotating rod 5, the mixing plate 6 rotates accordingly, stirring the materials in the tank. At the same time, the rotating rod 5 also drives the circular plate 7 to rotate. When the circular plate 7 rotates, the semi-circular block 8 also rotates. During the rotation, the semi-circular block 8 periodically presses against the connecting plate 10. When the connecting plate 10 is pushed by the semi-circular block 8, the sliding rod 9 will move accordingly, thereby driving... The tamper 12 tamperes with the material. Through the combined action of stirring and tampering, large-diameter aggregates, asphalt, mineral powder, and additives are fully and evenly mixed, effectively avoiding aggregate segregation and uneven asphalt distribution, and ensuring the consistency of the mixture. When the semicircular block 8 rotates away and the connecting plate 10 is no longer under pressure, the spring 11 will play its role, springing the connecting plate 10 back to its original position and driving the slide bar 9 to reset. During the feeding stage, the control valve 2 is opened, and the mixed material will flow out from the feeding port 14 and finally fall onto the road surface through the through hole.

[0025] Reference Figure 1 and Figure 3 The pressing assembly includes a support frame 15 fixedly connected to the top right side of the movable plate 1. A support plate 16 is fixedly connected to the top of the support frame 15. A second motor 17 is fixedly connected to the right end of the support plate 16. The drive end of the second motor 17 passes through the support plate 16 and is fixedly connected to an eccentric wheel 18. A rotating block 19 is rotatably connected to the left end of the eccentric wheel 18. A connecting block 20 is rotatably connected to the bottom end of the rotating block 19. A moving rod 21 is slidably connected to the inner wall of the support frame 15. A pressure plate 22 is fixedly connected to the bottom end of the moving rod 21. The top end of the moving rod 21 is rotatably connected to the bottom end of the connecting block 20. Limiting rods 23 are fixedly connected to both sides of the top end of the pressure plate 22. The outer walls of the limiting rods 23 are slidably connected to the inner wall of the support frame 15.

[0026] Specifically, when it is necessary to compact the large-particle-size permeable asphalt mixture for road paving, the second motor 17 is started. The drive end of the second motor 17 begins to rotate, driving the eccentric wheel 18 connected to it to rotate synchronously. During the rotation, the eccentric wheel 18, due to its eccentric structure, pushes the rotating block 19 to move. The movement of the rotating block 19 causes the connecting block 20 to move accordingly. The connecting block 20 then drives the moving rod 21 to move. As the moving rod 21 moves, the pressure plate 22 connected to it applies pressure to the material on the road surface. Through this mechanical transmission process, the pressure plate 22 can compact the large-particle-size permeable asphalt mixture. Applying high pressure to the permeable asphalt mixture with large particle size causes the aggregates in the mixture to be tightly interlocked, effectively expelling internal air, significantly reducing porosity, and greatly improving the compaction of the road surface. The eccentric wheel 18 rotates continuously, driving the pressure plate 22 to move up and down reciprocally, continuously compacting the road surface material. During the up and down movement of the pressure plate 22, the limiting rod 23 slides synchronously inside the support frame 15. The presence of the limiting rod 23 plays a key role, greatly improving the stability of the pressure plate 22 during movement, ensuring that the compaction operation can be carried out smoothly and efficiently, and providing a strong guarantee for obtaining a high-quality compacted road surface.

[0027] Working principle: First, the mixed materials are put into the mixing tank 3 through the feeding port 13. Then, the first motor 4 is started, and its drive end rotates, driving the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives the mixing plate 6 to rotate, stirring the materials. The rotating rod 5 also drives the circular plate 7 to rotate, which in turn drives the semi-circular block 8 to rotate. When the semi-circular block 8 rotates, it abuts against the connecting plate 10. When the connecting plate 10 is pushed, it drives the sliding rod 9 to move. When the sliding rod 9 moves, it drives the tamper rod 12 to tamper with the materials, thus ensuring that the large-diameter aggregates, asphalt, mineral powder, and additives are fully and evenly mixed, avoiding aggregate segregation and uneven asphalt distribution, and ensuring the consistency of the mixture. When the connecting plate 10 does not touch the semi-circular block 8, the spring 11 will bounce the connecting plate 10. When the connecting plate 10 is bounced, it drives the sliding rod 9 to reset. When discharging, the control is opened. The mixed material from valve 2 flows out from discharge port 14 and falls onto the road surface through the through hole. When compaction is required, the second motor 17 is started, and its drive end rotates, causing the eccentric wheel 18 to rotate. When the eccentric wheel 18 rotates, it drives the rotating block 19 to move. When the rotating block 19 moves, it drives the connecting block 20 to move. When the connecting block 20 moves, it drives the moving rod 21 to move. When the moving rod 21 moves, it drives the pressure plate 22 to compact the material on the road surface, thereby applying greater pressure to the large-particle permeable asphalt mixture, making the aggregates in the mixture tightly interlocked, effectively removing air, reducing porosity, and improving the compaction of the road surface. When the eccentric wheel 18 rotates, it drives the pressure plate 22 to move up and down. When the pressure plate 22 moves, it drives the limiting rod 23 to slide inside the support frame 15. The movement of the limiting rod 23 improves the stability of the pressure plate 22.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
