Detailed Implementation

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is an asphalt paving device for road construction, including a driving body 1, a storage component 2 installed on the driving body 1, a mixing component 3 installed inside the storage component 2, a baffle plate 4 installed on the lower end of the driving body 1, a pressing component 5 installed at one end of the driving body 1, an adjusting component 6 installed below the driving body 1, and a driving component 7 installed on the adjusting component 6.

[0032] The driving body 1 is used for walking, the mixing component 3 is used for mixing the asphalt in the storage component 2, the baffle plate 4 is used to prevent the asphalt from overflowing to both sides, the driving component 7 drives the adjusting component 6 to adjust the paving thickness, and the pressing component 5 is used to compact the paved asphalt.

[0033] In practical use, the raw materials are poured into the storage component 2, and stirred and kept warm by the mixing component 3, so that the asphalt remains in a liquid state and does not form a solid state, thus allowing it to be smoothly discharged onto the ground. The baffles 4 set on both sides can block it, so that the asphalt does not overflow to the sides and cause waste. The height can be adjusted by the drive component 7 driving the adjustment component 6, so that the thickness of the paved asphalt can be adjusted to meet various needs. Finally, the paved asphalt is compacted by the pressing component 5, thus completing the road asphalt paving.

[0034] This invention uses a mixing component 3 to stir and keep warm the material stored in the storage component 2, ensuring that the asphalt remains liquid and does not solidify. This guarantees smooth asphalt discharge and paving effect. Baffles 4 on both sides prevent asphalt from overflowing and wasting, reducing asphalt loss. The drive component 7 allows the adjustment component 6 to flexibly adjust its height, enabling the device to meet various paving thickness requirements and be suitable for multiple application scenarios, thus improving work efficiency.

[0035] In one embodiment, the storage component 2 includes a barrel 8, an arc-shaped opening 9 at the upper end of the barrel 8, arc-shaped slide rails 10 installed on both sides of the arc-shaped opening 9, a cover plate 11 slidably installed in the arc-shaped slide rails 10, the cover plate 11 can completely close the arc-shaped opening 9, and a discharge pipe 12 is installed at the lower end of the barrel 8, the opening of the discharge pipe 12 is located at the lower end of the drive body 1.

[0036] By sliding the cover plate 11 within its arc-shaped slide rail 10, the cover plate 11 can open and close the arc-shaped hopper 9, pouring asphalt into the barrel 8, and then driving its mixing component 3 to mix it. The inner wall of the barrel 8 is provided with a heating layer, which can heat the asphalt so that it does not solidify and remains in a flowing state, thus allowing the asphalt to be smoothly discharged through the discharge pipe 12, ensuring its paving effect.

[0037] In one embodiment, the stirring assembly 3 includes a stirring motor 13, the stirring motor 13 is mounted on the upper end of the barrel 8, the stirring motor 13 is mounted on the shaft of the stirring motor 13 and a rotating shaft 14 is mounted on the shaft of the stirring motor 13. The rotating shaft 14 passes through the barrel 8 and extends into the inner cavity, and a stirring frame 15 is mounted on the rotating shaft 14.

[0038] The stirring motor 13 is driven to rotate the stirring frame 15 through the rotating shaft 14, thereby stirring the inside of the barrel 8. The heating layer can fully heat the asphalt, keeping it in a liquid state, allowing for better flow and preventing blockage of the discharge pipe 12.

[0039] In one embodiment, the drive body 1 has a slot 16, and the drive assembly 7 includes a fixing frame 17. The fixing frame 17 is mounted on the upper surface of the drive body 1 and corresponds to the slot 16. A bidirectional screw 18 is rotatably mounted through the fixing frame 17. The thread directions at both ends of the bidirectional screw 18 are different. A first gear 19 is mounted through the bidirectional screw 18. The lengths of the bidirectional screw 18 on both sides of the first gear 19 are the same. A second gear 20 is mounted on one side of the first gear 19 and meshes with it. A first drive shaft 21 is mounted on the axis of the second gear 20. A drive motor 22 is mounted on the axis of the first drive shaft 21 and is mounted on the drive body 1.

[0040] When it is necessary to adjust the height of the adjusting component 6, the drive motor 22 can be driven to rotate the first gear 19 through the second gear 20, thereby rotating the bidirectional screw 18, which in turn drives the adjusting component 6 to move up and down, thereby adjusting its height to lay asphalt roads of different thicknesses.

[0041] In one embodiment, the adjustment component 6 includes an adjustment plate 23, which is installed at the lower end of the drive body 1 and corresponds to the slot 16. One end of the blocking plate 4 is provided with a first sliding groove 24, and the adjustment plate 23 can slide in cooperation with the first sliding groove 24. Telescopic folding rods 25 are rotatably installed at both ends of the upper surface of the adjustment plate 23. The upper end of the telescopic folding rods 25 passes through the slot 16 and is rotatably installed on the moving block 26. The moving block 26 is threadedly fitted on the bidirectional screw 18.

[0042] When different thicknesses of asphalt need to be laid, the bidirectional screw 18 can be rotated to move the moving block 26 at both ends, which in turn moves the adjusting plate 23 in the first slide groove 24 via the telescopic folding rod 25, thereby adjusting its height above the ground and adjusting the thickness of asphalt that can pass through at its lower end. This allows for flexible adjustment of the thickness of the asphalt to be laid, and is simple, quick, time-saving and labor-saving.

[0043] In one embodiment, for the aforementioned adjusting plate 23, a movable plate 27 is movably installed on one side of the adjusting plate 23, a sliding column 28 is installed on the upper end of the movable plate 27, and a second sliding groove 29 is installed on the upper surface of the driving body 1, and the sliding column 28 can slide and cooperate with the second sliding groove 29.

[0044] By installing a movable plate 27 on the adjusting plate 23, it can slide within the second sliding groove 29 via the sliding column 28. This allows the movable plate 27 to shift under the action of the second sliding groove 29 when the height of the adjusting plate 23 changes. This enables it to block the area at the upper end of the adjusting plate 23, ensuring that asphalt is only delivered at the height reserved below the adjusting plate 23, increasing the accuracy of its thickness, and resulting in better paving effect and smoother surface.

[0045] In summary, with the help of the above-mentioned technical solution of this utility model, asphalt is poured into the barrel 8 by opening and closing the arc-shaped hopper 9 through the sliding cover plate 11, and then the stirring motor 13 is driven to drive the stirring frame 15 to rotate through the rotating shaft 14, thereby stirring the inside of the barrel 8. The heating layer can fully heat the asphalt, keeping it in a liquid state, allowing for better flow and preventing blockage of the discharge pipe 12, so that it can be smoothly transported to the ground. The baffle plates 4 set on both sides can block it, so that the asphalt will not overflow to both sides and cause waste. When it is necessary to adjust the height of the adjusting component 6, the drive motor 22 is driven to drive the first gear 19 to rotate through the second gear 20, thereby rotating the bidirectional screw 18. The moving block 26 moves at both ends, causing the adjusting plate 23 to move within the first slide groove 24 via the telescopic folding rod 25, thereby adjusting its height above the ground and the thickness of the asphalt that can pass through its lower end. The movable plate 27 installed on the adjusting plate 23 slides within the second slide groove 29 via the sliding column 28, allowing the movable plate 27 to shift under the action of the second slide groove 29 when the height of the adjusting plate 23 changes. This blocks the area above the adjusting plate 23, ensuring that the asphalt is only transported at the pre-reserved height below the adjusting plate 23, thus allowing for flexible adjustment of the asphalt thickness. This process is simple, quick, and saves time and effort. Finally, the pressed component 5 compacts the laid asphalt, completing the road asphalt paving.

[0046] Through the above technical solutions, 1. The mixing component 3 can mix and keep warm the materials stored in the component 2, keeping the asphalt in a liquid state and preventing it from solidifying. This ensures smooth asphalt discharge and paving effect. The baffles 4 on both sides can block the asphalt from overflowing and causing waste, reducing asphalt loss. The driving component 7 allows the adjusting component 6 to be flexibly adjusted in height, thus enabling the device to meet various paving thickness requirements and be suitable for multiple application scenarios, improving work efficiency. 2. When different thicknesses of asphalt need to be paved, the bidirectional screw 18 can be rotated to move the moving block 26 at both ends. This allows the adjusting plate 23 to move within the first slide groove 24 via the telescopic folding rod 25, thereby adjusting its height above the ground and the thickness of the asphalt that can pass through at the bottom. This allows for flexible adjustment of the asphalt paving thickness, which is simple, quick, time-saving, and labor-saving.
