Technical Field

The utility model relates to the field of tunnel processing machinery, in particular to a small tunnel hammer-digging quick-change arm.

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.

However, the existing excavator belongs to large-scale equipment, generally can only be used in a wide open space, how to reduce the swing amplitude of the excavator, is one of the problems that the excavator is miniaturized and can be used in a narrow environment such as a tunnel and the like and needs to be solved urgently, wherein the largest factor restricting the application of the excavator in the narrow space such as the tunnel is that the swing arm system of the excavator occupies too large volume and is difficult to replace a working head after being folded.

SUMMERY OF THE UTILITY MODEL
