[0002] An excavator is an earth-moving machine used to dig materials above or below the surface and load them into transport vehicles or unload them to a stockpile. The three important parameters of an excavator include operating weight (mass), engine power, and bucket capacity. Excavators play an important role in engineering construction and have become one of the most important engineering machinery in engineering construction. In addition, excavators are available in two types: crawler all-terrain excavators and crawler excavators. Crawler all-terrain excavators can operate safely and effectively on complex terrains, and the excavator frame is the most important supporting component of the whole.

[0003] At present, when an excavator is excavating wet and soft muddy land, a large amount of soil will be deposited in the crawler track of the walking chassis, which increases the weight of the excavator, slows down the moving speed during excavation, reduces work efficiency, and increases the energy consumed by fuel when the excavator moves. Therefore, it is necessary to upgrade and transform the existing frame. For example, the application number is: 201920778884.1 "A side plate structure of an excavator frame" by arranging a wire brush and a mounting frame on the frame, and using the wire brush to clean the mud on the crawler track.
