[0002] The road roller is also called compactor, which is a kind of road repairing equipment, and is divided into two types of steel wheel type and tire type. The road roller belongs to the category of road equipment in engineering machinery, and is widely used in filling compaction operation of large engineering projects such as high-grade highway, railway, airport runway, dam and stadium, and can roll and press sandy, semi-cohesive and cohesive soil, roadbed stable soil and asphalt concrete pavement layer. The road roller is suitable for various compaction operations by the gravity of the machine itself, so that the rolled layer is permanently deformed and compacted.

[0003] In the prior art, the compactor is often used during road construction, and in order to prevent the mixture of soil, asphalt concrete, cement concrete fabric and the like from adhering to the steel wheel, a mud scraping plate is generally installed to scrape off the adhered mixture on the rolling steel wheel to improve the compaction quality. However, the mud scraping plate will gradually wear during use, especially when dealing with hard or sticky materials, long-term wear will cause the mud scraping plate to become less sharp or deformed, thereby reducing the effect of scraping off the mixture. In addition, the mud scraping plate may also be damaged due to collision with the road surface or other objects. Therefore, it needs to be replaced in time. However, the existing mud scraping plate is mostly connected to the frame of the road roller through multiple screws, studs or welding points, and the space for replacing the mud scraping plate is limited, which causes the connection points to be disassembled and assembled one by one when the mud scraping plate is replaced, thereby bringing inconvenience to the disassembly and replacement operation of the mud scraping plate.
