摘要： A system for providing suspension to a cab of an excavation machine such as a trencher or a surface mining machine. The system includes air cushions and elastomeric dampeners positioned between a platform and the cab. The air cushions allow for a larger displacement than the elastomeric dampeners. The air cushions have a lower natural frequency than the elastomeric dampeners. The elastomeric dampeners stabilize and support the cab in various degrees of freedom that are not supported by the air cushions.

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.
摘要翻译：公开了挖掘装置。挖掘装置包括具有从底盘的前端延伸到后端的长度的底盘。底盘也具有垂直于长度的宽度。悬臂可枢转地附接到底盘的后端。安装在吊杆上的切割部件。护罩结构至少部分地覆盖切割部件。真空源与护罩结构的内部流体连通，用于从护罩结构的内部抽出含有灰尘的空气。过滤器通过真空源过滤从护罩结构的内部抽取的空气。防尘屏障从护罩结构向下突出并沿着护罩结构的周边的至少一部分延伸。防尘屏障具有可透过切割部件产生的碎屑的结构，并且当防尘屏障从护罩结构向下延伸时，对防止隔离物的向内空气流动逐渐减小。
