[0002] An excavator, also known as an excavating machine, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and loads them into transport vehicles or unloads them to stockpiles. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rocks. The development of excavators is relatively rapid. Excavators have become one of the most important engineering machinery in engineering construction. The three most important parameters of excavators are: operating weight (mass), engine power and bucket capacity. The front end of the excavator bucket is usually equipped with multiple shovel teeth, which are easily damaged or broken by bumps, making it inconvenient for operators to replace the shovel teeth, affecting the subsequent use of the bucket.
