Description

Technical Field

[0001] The present application relates to the technical field of road construction equipment, and in particular to a road roller with a scraper that is easy to disassemble. Background Art

[0002] As a common piece of engineering machinery, road rollers play a vital role in road construction. They are primarily used for fill and compaction operations in large-scale projects such as highways, railways, and runways. They are used to compact stabilized roadbed soil, sandy, semi-cohesive, and cohesive soils, and asphalt concrete pavement layers. Using the force of gravity, rollers are suitable for various compaction operations, achieving permanent deformation and densification of the compacted layer.

[0003] Among them, road rollers are divided into two types: steel wheel type and tire type. The steel wheel is equipped with a scraper. During the driving process of the road roller, the scraper pushes the loose materials on the road surface to both sides of the road surface to achieve the purpose of leveling the road surface and ensure the flatness and quality of the road surface after construction.

[0004] Traditional roller blade designs present numerous challenges, particularly in terms of blade removal and maintenance. Existing blades are typically welded together, making replacement or repair complex and time-consuming, significantly impacting both construction efficiency and equipment maintenance costs. Summary of the Invention

After the screw passes through the through hole, it is threadedly connected with the nut, that is, the tool holder can be fixed to the positioning seat. The screw and the nut cooperate to facilitate the disassembly and installation of the tool holder.

[0015] Optionally, the bottom of the positioning seat is provided with a bevel 1, and the top of the tool holder is provided with a bevel 2 that cooperates with the bevel 1. The abutment between the bevel 1 and the bevel 2 can increase the contact area between the tool holder and the positioning seat.

[0016] By adopting the above technical solution, when the user uses it, the first bevel and the second bevel abut against each other, which can increase the contact area between the tool holder and the positioning seat, making the connection between the tool holder and the positioning seat more stable.

[0017] Optionally, a rotating shaft is fixedly connected to the positioning seat, and the rotating shaft is rotatably connected to the fixing frame; the positioning assembly includes a positioning shaft rotatably connected to both ends of the fixing frame, and locking blocks are fixedly connected to both ends of the positioning seat, and the locking blocks are slidably connected to the positioning shaft.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By making the scraper detachably connected to the fixing frame, instead of the traditional scraper and fixing frame being integrally formed or welded, the scraper can be easily repaired or replaced without affecting the construction efficiency and reducing the maintenance cost of the equipment;
