Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a crushing device for excavators. Background Technology

[0002] As is well known, an excavator, also known as a digging machine or a soil excavator, is an earthmoving machine that uses a bucket to dig materials above or below the machine's bearing surface and load them into transport vehicles or unload them into a stockpile. The materials excavated by excavators are mainly soil, coal, silt, and pre-loosened soil and rock. In recent years, the development of construction machinery has been relatively rapid, and excavators have become one of the most important construction machines. The three most important parameters of an excavator are: operating weight (mass), engine power, and bucket capacity. The appropriate bucket is selected based on the intended use of the excavator.

[0003] Currently, existing excavators equipped with hydraulic breakers are generally single-breaker excavators, with only one chisel on each breaker. When performing breaking work, the breaking force of the independent chisel is limited. When encountering hard rocks or other objects, it may require prolonged vibration to break the breaker, which can easily lead to damage to the breaker and result in low work efficiency.

[0004] Therefore, in response to the aforementioned technologies, we propose a crushing device for excavators. Utility Model Content
