Description

Technical Field

[0001] The invention belongs to the technical field of road paving, and in particular relates to an automatic road paving device. Background Art

[0002] With the continuous development of social economy and the continuous improvement of people's living standards, many families have private cars. Due to the increasing number of private cars, it has brought severe traffic pressure to the roads. Therefore, the highway management department is vigorously developing highway construction. In the process of highway construction, concrete pavement construction leveling machines are often needed to achieve the leveling of the road surface.

[0003] For example, the existing Chinese patent publication number CN114775375B discloses a road pavement asphalt mixture paving device, which specifically relates to the field of road paving, including a mixing box, a mounting plate fixedly installed at the bottom end of the mixing box, a scraper arranged at the bottom end of the mixing box behind the mounting plate, a connecting frame arranged at the bottom end of the mixing box behind the scraper, and an opening is opened on the outer surface of the bottom end of the mixing box. The present invention is provided with a mixing box, a baffle, a sliding button and a side plate. During the paving process, the cylinder inside the top frame can be started to push the side plate downward, and the two sides of the paved asphalt can be arranged through the side plates on both sides to avoid the asphalt on both sides of the road from being scattered, thereby improving the paving effect of the asphalt. When the spacing between the side plates on both sides needs to be adjusted, the motor on the mounting plate can be started, and the screw rod is driven to rotate by the motor. The screw rod is threadedly connected to the top frame, which will drive the top frame to move along the screw rod, thereby adjusting the position of the side plate, which is more practical.

[0004] However, during the use of the above patent, when paving the ground, the ground can only be compacted and flattened at an angle (for example, the ground can only be compacted by moving vertically downward), which will result in the asphalt on the road surface being insufficiently compacted and not firm during the compaction process, and it cannot be combined with the road surface when the road surface has upslopes or downslopes, resulting in poor asphalt leveling effect, affecting the adhesion of asphalt on the road surface, and also affecting the subsequent use of the road surface.

[0016] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0017] Firstly, when the height position of the asphalt road surface is adjusted, the striking motor of the present invention drives the eccentric shaft to rotate on the angle adjustment frame, which drives the position of the connecting plate to rotate, thereby driving the position of the striking plate to move up and down and vibrate continuously on the angle adjustment frame, thereby vibrating and striking and leveling the asphalt road surface; and in the process of striking, the angle of the angle adjustment frame can be driven by the operation of the dual-axis motor on the adjustment seat, and when the asphalt on the uphill or downhill road surface is leveled and compacted, the angle position of the striking plate can be adjusted to adapt to the uphill or downhill road surface angle, so that the striking plate can be better combined with the road surface, and the asphalt leveling and compacting effect is better.

[0018] Secondly, the present invention drives the first sprocket to rotate by adjusting the motor, and then drives the second sprocket to rotate through the chain, so as to drive the adjusting shaft to rotate in the slide groove.

[0019] Thirdly, in the process of paving, after the adjusting plate adjusts and adjusts the thickness of the asphalt, the asphalt will also move to the two ends of the adjusting plate. At this time, the asphalt on both sides can be blocked and blocked by the rotating plate, and the expansion plate can move horizontally on the adjusting plate.

[0020] During the rotation of the adjusting plate, the rotating plate needs to be in a horizontal state. At this time, after each angular position adjustment of the adjusting plate, the nut can be loosened to allow the rotating plate to rotate on the rotating screw so that the position of the rotating plate is in a horizontal state. After that, the nut can be rotated to fix the position of the rotating plate in a horizontal state. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Preferably, the angle adjustment structure 2 includes an adjusting motor 21 horizontally arranged in the paver 1, a first sprocket 22 is provided on the main shaft of the adjusting motor 21, an adjusting shaft 25 is provided in the slide groove 11, a second sprocket 23 is provided on the adjusting shaft 25, a chain 24 is provided between the first sprocket 22 and the second sprocket 23, and an adjusting plate 26 is provided on the adjusting shaft 25.

[0036] When in use, the first sprocket 22 is driven to rotate by the adjusting motor 21, and the second sprocket 23 is driven to rotate through the chain 24, so that the adjusting shaft 25 can be driven to rotate in the slide groove 11. The rotation of the adjusting shaft 25 can drive the angle position of the adjusting plate 26 to change. When paving the thickness of asphalt, the angle position of the adjusting plate 26 can be adjusted according to the needs of asphalt paving, so that the height of the adjusting plate 26 is in the best and most suitable position, and the asphalt is paved by moving the paver 1 forward.

The horizontal adjustment component 31 is arranged in the sliding groove 12 and the horizontal adjustment component 31 is slidably matched with the sliding groove 12. Two angle rotation components 32 are provided, and the two angle rotation components 32 are respectively rotatably connected to the two adjustment ends of the horizontal adjustment component 31. Two vibration and knocking components 33 are provided, and the two vibration and knocking components 33 are respectively arranged on the two angle rotation components 32.

[0042] The rotating motor 311 drives the bidirectional screw rod 313 to rotate in the sliding groove 12, which will drive the two adjustment seats 314 to move relative to or towards each other on the sliding rod 312, and will drive the position of the corresponding vibration knocking assembly 33 to move, so that when the asphalt on the road surface is knocked and vibrated, all-round knocking operations are performed on various positions on the road surface, so that the asphalt road surface is fully compacted.

The striking plate 333 is slidably connected to the angle adjustment frame 321. The two ends of the connecting plate 334 are rotatably connected to the eccentric shaft 332 and the striking plate 333, respectively.

[0045] In this embodiment, when the height position of the asphalt road surface is adjusted, the striking motor drives the eccentric shaft 332 to rotate on the angle adjustment frame 321, which will drive the position of the connecting plate 334 to rotate, thereby driving the position of the striking plate 333 to move up and down and vibrate on the angle adjustment frame 321, and vibrate and strike and level the asphalt road surface; and in the process of striking, the dual-axis motor 322 can also drive the angle of the angle of the angle adjustment frame 321 on the adjustment seat 314 to rotate. When the asphalt on the uphill or downhill road surface is leveled and compacted, the angle position of the striking plate 333 can be adjusted to adapt to the uphill or downhill road surface angle, so that the striking plate 333 can be better combined with the road surface, so that the asphalt leveling and compacting effect is better.

The paver 1 moves forward to drive the flattening roller 41 to rotate, and the asphalt pavement is flattened again, so that there will be no unevenness on the pavement to affect the subsequent work of the pavement.
