Description

Technical Field

[0001] The utility model belongs to the technical field of excavators, and in particular relates to a cab of an underground mining excavator. Background Art

[0002] Underground refers to the working environment at the bottom of a mine. A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Sometimes, the inclined shafts, vertical shafts, and horizontal shafts in the underground development of mines are also called mines. When digging and transporting underground, the work is mostly done by excavators. Excavators, also known as excavation machinery, are earth-moving machines that use buckets to dig materials above or below the bearing surface and load them into transport vehicles or unload them to stockpiles.

[0003] Due to the small space underground and the susceptibility to rockfall, the existing excavator cab has low main frame strength, insufficient top strength, and no high-strength protective net on the front right and rear sides. It cannot effectively protect the driver's safety in mines with extremely high danger factors. At the same time, the cab height is too high and cannot effectively operate efficiently in the narrow space underground. Utility Model Content
