摘要:
An excavation apparatus is disclosed. The excavation apparatus includes a chassis having a length that extends from a front end to a rear end of the chassis. The chassis also has a width oriented perpendicular to the length. A boom is pivotally attached to the rear end of the chassis. A cutting component mounted to the boom. A shroud structure at least partially covers the cutting component. A source of vacuum is in fluid communication with an interior of the shroud structure for drawing air containing dust from the interior of the shroud structure. A filter filters the air drawn from the interior of the shroud structure by the source of vacuum. A dust barrier projects downwardly from the shroud structure and extends along at least a portion of a perimeter of the shroud structure. The dust barrier has a construction that is pervious to debris generated by the cutting component and that provides gradually reduced restriction to inward air flow through the dust barrier as the dust barrier extends downwardly from the shroud structure.
