Description

Technical Field

[0001] The utility model relates to the technical field of excavators, in particular to a cleaning structure of an excavator bucket. Background Art

[0002] An excavator, also known as an excavator or a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the supporting surface and load them into transport vehicles or unload them to stockpiles. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rocks. The excavator bucket is the component of the excavator that directly contacts the material and performs operations such as excavation, loading, and transportation.

[0003] When the excavator bucket is working for a long time, mud and other impurities will accumulate inside the bucket, which will increase the weight of the bucket and occupy the internal space. The digging ability of the bucket will be reduced due to the adhesion of mud, resulting in insufficient digging depth, affecting the efficiency and quality of digging. Utility Model Content
