Description

Technical Field

[0001] The utility model relates to the field of paving and vibrating devices, in particular to an asphalt paving and vibrating device for municipal roads and bridges. Background Art

[0002] When repairing the road and bridge pavement, asphalt paving and compaction is an important and indispensable step. When paving and compacting, a paving and compacting device is needed. Most paving and compacting devices on the market are equipped with a lower hopper and a roller. The roller compacts after the hopper discharges the material.

[0003] At present, the application number is CN220789336U, an asphalt paving and flattening device, belonging to the field of asphalt paving and flattening technology, including a paving hopper and a flattening assembly, the flattening assembly is connected to the paving hopper through a traction assembly; the flattening assembly includes a cylindrical pressure roller, end covers fixed at both ends of the pressure roller, and a shock mechanism arranged inside the pressure roller and located between the two end covers; the shock mechanism includes a number of equally spaced annular plates and a lifting plate and a punch block arranged between each two adjacent annular plates, when the pressure roller rolls, the lifting plate can lift the punch block to a high position and then let it fall freely. The utility model utilizes the cooperation of the lifting plate and the punch block to convert the rolling of the pressure roller into the free fall motion of the punch block, so as to use the vibration generated when the punch block hits the inner bottom surface of the pressure roller to compact the asphalt laid by the paving hopper, and each time the pressure roller rolls one circle, it will generate a vibration equal to the number of punch blocks, and the compaction and flattening effect is good.

[0004] In summary, although the paving and flattening device can achieve the paving function, its paving hopper cannot evenly spread the asphalt material on the ground during paving and unloading. When paving, the asphalt material is easily unevenly spread, resulting in uneven thickness of the asphalt material during subsequent compaction. In addition, the paving and flattening device lacks a structure that can control the paving thickness. When in use, the asphalt paving thickness cannot be adjusted, which makes it easy for the thickness of the paved asphalt to be different from the thickness of the original road surface when the road surface is repaired.
