Description

Technical Field

[0001] The present application relates to the technical field of road paving, and in particular to a device for paving gravel on an asphalt concrete pavement. Background Art

[0002] In the initial stage of asphalt concrete road construction, the road surface is often made of soft soil. In order to improve the bearing capacity and durability of the road surface, the construction team usually uses a roller to compact the original mud surface. However, due to the natural softness of the soil, the road surface without further treatment is very likely to sag during subsequent construction. Therefore, laying a layer of crushed stone becomes a key step to ensure the stability of the subsequent asphalt concrete layer and extend its service life.

[0003] At present, there are some gravel laying devices on the market, such as the device with publication number CN220704256U, which have shown certain practicality in construction. Such devices are usually designed with a storage box for pre-storing concrete gravel and evenly mixing it before laying. In addition, it is also equipped with a sliding baffle plate to control the amount of gravel falling, and a crushing box to handle larger gravel particles to ensure that the laid gravel has a uniform particle size. Finally, the crushed gravel is evenly laid on the ground through the opening of the paving plate.

[0004] However, although these devices perform well in mixing and crushing gravel, they also have a significant problem: a large amount of dust is generated during the mixing and crushing process. This dust will not only escape from the device's feeding port and the opening of the paving plate, but will also quickly spread in the air, causing a significant drop in the air quality around the construction area. If the construction workers are in this dirty environment for a long time, their health will be seriously threatened, and there is room for improvement. Summary of the invention

[0058] When the handle 12 is in a vertical state, the adjusting rod 5 slides along the guiding inclined surface 711 to abut against the upper end of the vertical rod 71, and the first compression spring 742 is compressed, so that the vertical rod 71, the cleaning rod 72 and the cleaning brush 73 move downward as a whole. In this state, the cleaning brush 73 can abut against the road surface paved with gravel, making the road surface paved with gravel more flat.

[0059] When the handle 12 is in an upward 45-degree position, the end of the adjusting rod 5 is offset from the vertical rod 71. At this time, the first compression spring 742 in a compressed state squeezes the first baffle 741, causing the vertical rod 71 to move upward, and drives the cleaning rod 72 and the cleaning brush 73 to move upward to maintain a distance from the road surface.
