[0015] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1-3 As shown, an asphalt paving device includes a base plate 2, a connecting ear 3 is provided on one side of the base plate 2, two grooves 4 are provided on the base plate 2, and the opening of the groove 4 is set upward. It also includes a push plate 5, two hanging plates 6 are provided on one side of the push plate 5, and a plurality of rollers 7 are evenly provided on one side of the hanging plate 6. The rollers 7 are located inside the groove 4 to reduce the resistance of the push plate 5 when it moves on the base plate 2. A first hydraulic cylinder 8 is provided on one side of the base plate 2, and the output end of the first hydraulic cylinder 8 is fixedly connected to one end of the push plate 5. 2 is provided with a guide rod 9 and a slide rod 10 on one side, and the two ends of the guide rod 9 and the slide rod 10 are fixedly connected to the bottom plate 2 through the side plates 11 respectively. A fixed plate 12 and a movable plate 13 are provided on one side of the push plate 5. The fixed plate 12 is fixed on the push plate 5, and the guide rod 9 and the slide rod 10 pass through the fixed plate 12 and are slidably connected to the slide rod 10. A sleeve 14 is provided on one side of the fixed plate 12, and a second hydraulic cylinder 15 is provided inside the sleeve 14. The output end of the second hydraulic cylinder 15 is fixedly connected to the movable plate 13.

[0017] When in use, first install the paving device on the engineering vehicle through the connecting ear 3 so as to drive the paving device to move. Before paving the asphalt 1, first pile the asphalt 1 on the center of the road surface to be paved, then drive the engineering vehicle to the side of the road surface to be paved with asphalt 1, and keep the engineering vehicle and the road surface to be paved parallel. Then start the first hydraulic cylinder 8, and control the movement of the push plate 5 on the side of the bottom plate 2 by the first hydraulic cylinder 8. During the movement of the push plate 5, the fixed plate 12 on one side of the push plate 5 moves to the side of the road surface to be paved, and the distance between this side and the engineering vehicle is kept parallel. The distance is greater than the distance between the other side and the engineering vehicle. When the fixed plate 12 reaches the specified position, the output end of the first hydraulic cylinder 8 stops moving, and then the second hydraulic cylinder 15 is started, and the movable plate 13 is driven to move by the output end of the second hydraulic cylinder 15, so that the movable plate 13 moves to the other side of the road to be paved. When the movable plate 13 moves to the predetermined position, the fixed plate 12 and the movable plate 13 are respectively located on both sides of the road to be paved, and then the engineering vehicle is controlled to move. When the engineering vehicle moves, the asphalt 1 on the road surface is paved through the push plate 5 and the fixed plate 12 and the movable plate 13.

[0018] Furthermore, it also includes a dividing plate 16, which is located between the fixed plate 12 and the movable plate 13, and the dividing plate 16 is slidably connected to the slide bar 10. A fixed block 17 is provided on the dividing plate 16, and the fixed block 17 is slidably connected to the guide rod 9. Springs 18 are respectively provided on the guide rod 9 between the fixed plate 12 and the fixed block 17 and the guide rod 9 between the movable plate 13 and the fixed block 17. A through groove for the sleeve 14 to pass through is provided on the dividing plate 16. The two springs 18 on the guide rod 9 are always in a compressed state. When the movable plate 13 is controlled to move by the second hydraulic cylinder 15, the two springs 18 are compressed. 8 will be further compressed or stretched as the movable plate 13 moves, so that the dividing plate 16 can be in the middle position between the movable plate 13 and the fixed plate 12 as much as possible. When the dividing plate 16 moves with the engineering vehicle, it can push part of the asphalt 1 piled in the center of the road surface to be paved to both sides of the center of the road surface to be paved, thereby speeding up the movement speed of the asphalt 1 to both sides, improving the paving efficiency of the asphalt 1, avoiding a large amount of asphalt 1 from accumulating in the center of the road surface to be paved, and ensuring that there is sufficient asphalt 1 on both sides of the center of the road surface to be paved, thereby improving the paving quality of the asphalt 1.

[0019] Furthermore, a baffle plate 19 is provided on the dividing plate 16 and below the slide bar 10 to prevent excessive accumulation of the asphalt 1 on the dividing plate 16, while also reducing the accumulation height of the asphalt 1 on the dividing plate 16 and protecting the slide bar 10 to prevent excessive adhesion of the asphalt 1 to the slide bar 10, thereby ensuring smooth coordination between the dividing plate 16 and the slide bar 10.

[0020] Furthermore, the retaining plate 19 is tilted upward, which can effectively reduce the amount of asphalt 1 that moves onto the retaining plate 19 during the paving process.

[0021] Furthermore, the ends of the fixed plate 12 and the movable plate 13 away from the push plate 5 are both arranged toward the outside of the push plate 5, so that the asphalt 1 can be placed between the fixed plate 12 and the movable plate 13 as much as possible during the paving process, reducing the waste of asphalt 1.

[0022] When the paving device is in use, the positions of the fixed plate 12 and the movable plate 13 can be quickly adjusted, thereby adjusting the distance between the fixed plate 12 and the movable plate 13, so that the paving device can be used to pave asphalt 1 on a variety of road surfaces of different widths, reducing the replacement of the paving device, improving the paving efficiency, and achieving good use effect.

[0023] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
