Description

Technical Field

[0001] The utility model relates to the technical field of road construction, and more specifically, to a road construction paving device. Background Art

[0002] Road engineering refers to the entire process of planning, design, construction, maintenance and management of roads as the object and the engineering entities involved. When constructing roads, it is necessary to use a paver for construction work. A paver is a construction equipment used for paving various materials on the base and surface layers of roads. It is a machine that spreads asphalt mixture on the road base and performs preliminary compaction and leveling.

[0003] In the existing technology, after the asphalt is paved on the road surface, it is necessary to manually spread the concrete evenly. However, manual paving will waste human resources and affect the work progress. When paving is required, the roller rotates with the movement of the paver. The existing paver is very inconvenient to adjust the height of the roller. In addition, when rolling and smoothing the asphalt, some liquid asphalt often adheres to the surface of the roller. If it is not handled in time, it is easy to dry and fix on the surface of the roller, affecting the subsequent paving work. Utility Model Content

[0031] In this embodiment, when in use, asphalt is discharged and paved through the discharge box 3 on the paving vehicle 1 (the moving wheels are not shown). As needed, the adjusting cylinder 4 is driven, and the output end of the adjusting cylinder 4 drives the adjusting box 5 to adjust the height. At the same time, the adjusting motor 18 is driven, and the motor shaft of the adjusting motor 18 drives the first bevel gear 19 to rotate, and drives the material-discharging rod 6 and the material-discharging blade 7 to rotate through the second bevel gear 20, thereby driving the asphalt to be spread to both sides, thereby improving the paving effect. At the same time, when the paving vehicle 1 is moving, the hydraulic cylinder 13 is driven, and the hydraulic cylinder 13 drives the driving shaft 14 and the steering shaft 9 to rotate. When the steering shaft 9 rotates, it drives the connecting rod 10 and the roller 11 to rotate downward. When the roller 11 moves downward and rotates, the asphalt is compacted. The wear resistance and service life of the roller 11 are improved by the wear-resistant sheet 28, and the wear-resistant sheet 28 is convenient to replace by the fixing bolt 30.

[0032] See also Figure 4-5As an implementation method of the scraper 16: a cleaning plate 21 is provided on the cleaning shaft 15, a mounting groove 22 is provided on the cleaning plate 21, a mounting block 23 is provided on the scraper 16, an elastic pad 24 is provided between the mounting groove 22 and the mounting block 23, mounting holes 25 are provided on both sides of the mounting block 23, mounting bolts 26 are provided on the mounting holes 25, and a toggle piece 27 is provided on the mounting bolts 26.

[0033] More specifically, when the roller 11 rotates, the asphalt will stick to it.

The cleaned asphalt will directly slide to the ground due to the inclined arrangement of the scraper 16. When installing and disassembling the scraper 16, the mounting block 23 of the scraper 16 is extended into the mounting groove 22, and the connection tightness between the mounting block 23 and the mounting groove 22 is improved by the elastic pad 24. Finally, it is installed in the mounting hole 25 by the mounting bolts 26, and the positions of the two sides of the mounting block 23 are limited, thereby fixing the position of the mounting block 23 in the mounting groove 22, and then fixing the scraper 16 on the cleaning plate 21.

[0034] In summary, when the overall equipment is in use or running: when in use, the asphalt is discharged and paved through the discharge box 3 on the paving vehicle 1, and the adjusting cylinder 4 is driven as needed, and the output end of the adjusting cylinder 4 drives the adjusting box 5 to adjust the height, and at the same time drives the adjusting motor 18, and the motor shaft of the adjusting motor 18 drives the first bevel gear 19 to rotate, and drives the material discharging rod 6 and the material discharging blade 7 to rotate through the second bevel gear 20, thereby driving the asphalt to be spread to both sides, thereby improving the paving effect, and at the same time, when the paving vehicle 1 is moving, it drives the hydraulic cylinder 13, and the hydraulic cylinder 13 drives the driving shaft 14 and the steering shaft 9 to rotate, and when the steering shaft 9 rotates, it drives the connecting rod 10 and the roller 11 to rotate downward, and when the roller 11 moves downward and rotates, the asphalt is compacted, and the wear resistance and service life of the roller 11 are improved by the wear-resistant plate 28, and the wear-resistant plate 28 is convenient to replace by the fixing bolt 30.

[0035] When the roller 11 rotates, the asphalt will stick to it. Under the elastic force of the torsion spring 17, the cleaning shaft 15 makes the scraper 16 have a force pointing to the roller 11, so that the scraper 16 is in close contact with the roller 11, and the asphalt on the roller 11 is cleaned by the scraper 16. The cleaned asphalt will directly slide to the ground due to the inclined arrangement of the scraper 16. When installing and disassembling the scraper 16, the mounting block 23 of the scraper 16 is extended into the mounting groove 22, and the connection tightness between the mounting block 23 and the mounting groove 22 is improved by the elastic pad 24. Finally, it is installed in the mounting hole 25 by the mounting bolts 26, and the positions of the two sides of the mounting block 23 are limited, thereby fixing the position of the mounting block 23 in the mounting groove 22, and then fixing the scraper 16 on the cleaning plate 21.
