Local dust extraction system for an excavation machine

摘要

The present disclosure relates to an air cleaning system for an off-road excavation apparatus. The off-road excavation apparatus includes an excavating component and a shroud assembly that at least partially covers the excavating component. The shroud assembly includes a first shroud component and a second shroud component. The first shroud component is moveable relative to the second shroud component to allow access to the excavating component. The air cleaning system draws air from inside the shroud assembly and includes an air cleaner, an air conduit and an air moving device that are all carried by the first shroud component as the first shroud component is moved relative to the second shroud component.

主权项

1. A system for capturing dust generated by an excavation component carrying a plurality of cutting teeth, the excavation component being rotatable about a central axis of the excavation component, the system comprising:
a shroud for at least partially covering the excavation component, the shroud defining a local dust extraction volume; and a first intake conduit positioned within the local dust extraction volume between the shroud and the excavation component, the first intake conduit defining a length that extends from an air evacuation end to an opposite distal end, wherein a vacuum is attached at the air evacuation end of the first intake conduit, the first intake conduit defining a plurality of air intake openings that are spaced-apart along the length of the first intake conduit between the air evacuation end and the opposite distal end.
