Problems solved by technology

[0003] However, in the process of laying asphalt on the road in the prior art, in order to make the asphalt fit the ground better, the asphalt needs to be compacted. In the prior art, the asphalt is manually compacted, which is time-consuming and labor-intensive. In the existing technology, a trolley is usually used to transport asphalt. During the movement of the trolley, the asphalt in the trolley is poured out on the ground to achieve the effect of overlaying asphalt. However, due to uneven road surface or uneven discharge of asphalt, the asphalt on the road surface will Stacking and ups and downs appear, so when compacting asphalt, it is easy to cause uneven distribution of compacted asphalt and poor compaction effect

Abstract

The invention relates to the field of road construction equipment, and discloses an asphalt paving device forold cement concrete pavement reconstruction. The device comprises a driving box, a storage barrel is arranged in the driving box, a discharge port communicated with the bottom of the storage barrel is formed in the bottom of the driving box, a compaction roller is connected to the bottom of the driving box in the moving direction of the driving box, a supporting plate is fixedly connected to the top wall of the driving box, a rotating shaft is rotatably connected to the supporting plate, a swing rod is fixedly connected to the rotating shaft, the bottom end of the swing rod extends out of the bottom of the driving box and is fixedly connected with a flattening roller, a swing hole for the swing rod to swing is formed in the bottom of the driving box, and a driving unit for driving the swing rod to swing back and forth in the moving direction of the driving box is arranged in the driving box. The asphalt paving device can effectively improve the asphalt compacting effect.

Description

technical field [0001] The invention relates to the field of road construction equipment, in particular to an asphalt overlaying device for rebuilding old cement concrete road surfaces. Background technique [0002] At present, in order to improve the road quality and improve the comfort of the public on road driving, it is very common to transform the old cement concrete pavement. At present, in the way of transforming the old cement concrete pavement, it is mostly adopted to add asphalt concrete surface layer on the old cement concrete pavement to form a composite pavement. [0003] However, in the process of laying asphalt on the road in the prior art, in order to make the asphalt fit the ground better, the asphalt needs to be compacted. In the prior art, the asphalt is manually compacted, which is time-consuming and labor-intensive. In the existing technology, a trolley is usually used to transport asphalt. During the movement of the trolley, the asphalt in the trolley ...
