[0042] The following is combined with Figure 1-6 This application is described in further detail.

[0043] The embodiment of the present application discloses an asphalt paving device based on highway construction. Figure 1 The asphalt paving device for highway construction includes a frame 1 and a traveling mechanism, a front hopper 2, a feeding mechanism 3, and a screed mechanism 4 mounted on the frame 1. The traveling mechanism controls the entire asphalt paving device as it moves on the road surface. The front hopper 2 is located at the front end of the frame 1 in the traveling direction and includes two side baffles 21, which are spaced apart. The screed mechanism 4 is located at the rear end of the frame 1 in the traveling direction. The feeding mechanism 3 connects the front hopper 2 and the screed mechanism 4 and is located below the gap between the two side baffles 21.

[0044] During use, the asphalt raw materials are poured into the front hopper 2 by a feeding truck, and then the feeding mechanism 3 is able to gradually transport the asphalt raw materials to the side of the ironing mechanism 4 and lay them on the ground. Finally, the ironing mechanism 4 is able to flatten the asphalt raw materials on the road surface, thereby forming an asphalt pavement.

[0045] Reference Figure 1 At this time, the inner sides of the two side guards 21 are movably provided with guide plates 5, and the side guards 21 are provided with vibration mechanisms 6, so that the vibration mechanisms 6 can control the vibration of the guide plates 5. The part of the side guards 21 located above the guide plates 5 is connected to the protective baffles 7, which cover the upper edge of the guide plates 5.

[0046] During operation, the vibrating mechanism 6 controls the continuous vibration of the guide plate 5, thereby reducing the possibility of asphalt feedstock being adsorbed within the front hopper 2, improving the convenience of asphalt feedstock transportation and ensuring the best possible asphalt paving results. Furthermore, the protective baffle 7 covers the gap between the upper edge of the guide plate 5 and the side baffle 21, reducing the possibility of asphalt feedstock becoming stuck in this gap.

[0047] Reference Figure 1 and Figure 2The upper end of the protective baffle 7 is rotatably connected to the side baffle 21, and the lower end of the protective baffle 7 is placed on the upper edge of the guide plate 5. In addition, the rotating portion of the protective baffle 7 is provided with a reverse thrust torsion spring 71, and the two ends of the reverse thrust torsion spring 71 are respectively connected to the side baffle 21 and the protective baffle 7.

[0048] When in use, the reverse thrust torsion spring 71 can make the protective baffle 7 have a tendency to rotate toward the guide plate 5, so that during the vibration of the guide plate 5, the protective baffle 7 can remain in contact with the upper edge of the guide plate 5, thereby maintaining protection for the gap between the upper edge of the guide plate 5 and the side baffle 21, reducing the possibility of asphalt raw materials getting stuck in the gap.

[0049] Reference Figure 3 The vibration mechanism 6 includes a motor, a rotating rod 61, several cams 62, and several return springs 63. The rotating rod 61 is located between the side fence 21 and the material guide plate 5 and is rotatably connected to the side fence 21. The cams 62 are fixedly connected to the rotating rod 61 and abut the material guide plate 5. The motor is mounted on the side fence 21, and its output end is connected to the rotating rod 61, allowing the motor to control the rotation of the rotating rod 61. The two ends of the return spring 63 are fixedly connected to the material guide plate 5 and the side fence 21, respectively, so that the return spring 63 can pull the material guide plate 5 toward the side fence 21.

[0050] When in use, the motor is turned on to control the rotation of the rotating rod 61, thereby driving the rotation of several cams 62, so that the cams 62 can continuously push the guide plate 5 to vibrate; and, under the traction of the reset spring 63, the guide plate 5 can have a reset effect after sliding, thereby increasing the vibration effect of the guide plate 5.

[0051] In other embodiments, the vibration mechanism 6 may also be directly configured as a plurality of vibration motors that control the vibration of the material guide plate 5 .

[0052] Reference Figure 3 、 Figure 4 and Figure 5 To enhance the stability of the guide plate 5 during vibration, the guide plate 5 is fixedly connected to a plurality of reinforcement columns 51. These columns 51 extend through and are slidably connected to the side baffle 21. Several return springs 63 are mounted on some of the reinforcement columns 51. Adjustment columns 52 are mounted on the portions of the reinforcement columns 51 not fitted with the return springs 63. These adjustment columns 52 are mounted and threadedly connected to the ends of the reinforcement columns 51 facing away from the guide plate 5. These adjustment columns 52 extend through and are slidably connected to the side baffle 21. A retaining ring 521 is fixedly mounted on the outer wall of the retaining column 52, which abuts the inner wall of the side baffle 21.

[0053] During use, the reinforcement column 51 can support and guide the sliding of the guide plate 5, thereby increasing the stability of the guide plate 5 during vibration. In addition, some of the reinforcement columns 51 can also support the return spring 63, increasing the effectiveness of the return spring 63. In addition, the adjustment column 52 can be rotated to allow the adjustment column 52 to slide relative to the reinforcement column 51, thereby allowing the retaining ring 521 on the adjustment column 52 to engage with the inner wall of the side guard 21 from different positions, thereby adjusting the support height of the guide plate 5 and the distance between the guide plate 5 and the side guard 21. As a result, when the cam 62 pushes the guide plate 5, the amplitude of the guide plate 5 can be adjusted, thereby increasing the effectiveness of use.

[0054] Reference Figure 5 and Figure 6 To reduce the possibility of loosening of the adjustment column 52 during vibration of the guide plate 5, a locking plate 53 is provided on the end of the adjustment column 52 away from the reinforcement column 51. The locking plate 53 is fixedly connected to a connecting pin 54. The connecting pin 54 is a prismatic structure, coaxially extending through the reinforcement column 51 and slidably connected. A toothed ring 56 is fixedly connected to the facing surface of the locking plate 53 and the adjustment column 52, and the two toothed rings 56 are mutually meshed. A locking bolt 55 is fixedly connected to the reinforcement column 51. The end of the locking bolt 55 away from the reinforcement column 51 passes through the connecting pin 54 and the locking plate 53 and is threadedly connected to a plurality of clamping nuts 551. The multiple clamping nuts 551 are stacked and abut the side of the locking plate 53 facing away from the adjustment column 52.

[0055] When the adjusting post 52 rotates, the locking plate 53 slides, causing the toothed ring 56 on the locking plate 53 to mesh with the toothed ring 56 on the adjusting post 52, and then tightening the clamping nut 551. At this time, under the action of the connecting pin 54, the rotation of the adjusting post 52 can be restricted by restricting the rotation of the locking plate 53, thereby achieving the purpose of reinforcing the adjusting post 52, so as to reduce the possibility of the adjusting post 52 loosening during the vibration of the guide plate 5.

[0056] The working principle of an asphalt paving device for highway construction according to an embodiment of the present application is as follows: During operation, a feeding mechanism 3 gradually conveys the asphalt raw material within the front hopper 2 to the side of the screed mechanism 4 and lays it on the ground. During the asphalt raw material conveying process, a vibration mechanism 6 controls the continuous vibration of the guide plate 5, thereby reducing the possibility of asphalt raw material adsorption within the front hopper 2, improving the convenience of asphalt raw material conveyance and ensuring the asphalt paving effect. Furthermore, a protective baffle 7 covers the gap between the upper edge of the guide plate 5 and the side baffle 21, reducing the possibility of asphalt raw material becoming stuck in this gap.

[0057] The present application also discloses an asphalt paving method for highway construction, comprising the following steps:

[0058] Base treatment: rolling and cleaning the base;

[0059] Inspection well protection: Use protective film or protective plate to cover the inspection well at the construction site;

[0060] Oil-permeable layer construction: spray the oil-permeable layer on the base road surface;

[0061] Asphalt paving: Use asphalt paving equipment to spread asphalt raw materials on the base road surface;

[0062] Road surface compaction: Use a roller to compact the asphalt pavement after paving.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
