Background

Excavators, also known as excavating machines, also known as excavators, are earth moving machines that excavate material above or below a load bearing surface with a bucket and load it into a transport vehicle or unload it to a stockyard. The materials excavated by the excavator mainly comprise soil, coal, silt, soil subjected to pre-loosening and rocks. In view of the development of construction machines in recent years, the development of excavators is relatively fast, and the excavator has become one of the most important construction machines in construction. Common excavator structures include power devices, working devices, swing mechanisms, control mechanisms, transmission mechanisms, traveling mechanisms, auxiliary facilities, and the like.

The main functions of the excavator blade are to remove front obstacles, clean the road surface, stabilize the machine body and the like. When the miniature excavator works on a slope, the dozer blade plays an important role, so that the machine body can be prevented from collapsing and stabilized, and the operation surface can be leveled for backfilling; when the miniature excavator walks, the blade is placed in the advancing direction, the bottom edge of the blade is flush with that of the track, and the functions of trenching, backfilling, leveling and the like are enhanced.
