Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a mechanical digging device which is convenient for cleaning. Background Art

[0002] An excavator, also known as an 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. Judging from the development of construction machinery in recent years, the development of excavators has been relatively rapid, and excavators have become one of the most important construction machinery in engineering construction.

[0003] After the excavator finishes work, it is necessary to clean the remaining soil inside the bucket. Currently, it is usually cleaned directly with a shovel or small tools. However, when there is too much dust inside the bucket, directly using a shovel or small tools to clean it will cause workers to inhale a lot of dust, affecting their health and being inefficient. For this reason, we propose a mechanical excavation device that is easy to clean to solve the above problem. Utility Model Content
