Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a roller for road paving. Background Art

[0002] A road roller, also known as a soil compactor, is a piece of road paving equipment. Among engineering machinery, road rollers belong to the category of road equipment and are widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, etc. They can compact sandy, semi-viscous and cohesive soils, roadbed stabilized soil, etc. The road roller uses the gravity of the machine itself and is suitable for various compaction operations, causing the compacted layer to produce permanent deformation and become dense. The road roller is indispensable when the road roller is in use. Existing road rollers mostly use cylindrical rollers with a hollow interior and a smooth surface. When this type of cylindrical roller is performing compaction operations, it will affect the compaction effect when it encounters protrusions. When rolling cohesive soil, the cohesive soil is easy to stick to the roller, causing the roller to carry the cohesive soil to other places, resulting in the soil surface being uneven and not smooth, affecting subsequent construction. Utility Model Content

[0004] A roller for road paving comprises a rotating shaft, on which a roller body is arranged, and the roller body comprises a support plate, which is fixedly connected to the rotating shaft, and the support plate comprises a central connecting cylinder, on which a plurality of supporting ribs are arranged in a circular array, and the supporting ribs are in the shape of a letter "I" and are rigidly connected to the connecting cylinder, and the outer ends of all the supporting ribs are rigidly connected to the inner side of a supporting ring, and the upper and lower parts of the outer end surface of the supporting ring are both arc-shaped surfaces, with a convexity in the middle.

[0005] A roller plate is provided between two adjacent support plates, and the roller plate is fixedly connected to the rotating shaft. The roller plate includes a central connecting ring, and a plurality of integral support plates are provided on the connecting ring in a circular array. The outer ends of all the support plates are integrally connected to the roller plate, and the outer end surface of the roller plate is provided with a circle of roller teeth, and the tooth tops of the roller teeth are higher than the highest point of the support plate.

[0006] As a preferred embodiment, the road pressing teeth are in a "V" shape.

[0007] As a preferred solution, sealing rings are provided at both ends of the roller body, and the sealing rings are fixedly connected to the rotating shaft.

[0008] As a preferred solution, the tooth top of the roller teeth is 6-15 mm higher than the highest point of the support plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the roller of the utility model is provided with a supporting plate and a roller plate, which compact the road surface when performing the road rolling operation, and the design of the supporting plate and the roller plate can crush and flatten protrusions or other hard blocks, and the design of the roller teeth allows sticky soil to fall off as the roller rotates, thereby ensuring the flatness of the compacted road surface and not affecting subsequent construction.
