摘要： A berm clearing attachment for removable securement to a road clearing vehicle, such as a bulldozer, road grader, hi-lift, dump truck, tractor, or skid-steer loader, for side or lateral dozing accumulated dirt and debris off of roads and road berms and away from guiderails by reciprocating laterally with respect to the longitudinal axis of the road clearing vehicle as the vehicle travels on the road and road berm. The berm clearing attachment includes a support framework removably securable to the front of the road clearing vehicle, and when used with the skid loader, the support framework would be removably securable to the front mounting plate of the loader. The berm clearing attachment includes an elongated cylinder housing mounted to the support framework transverse to the axis of travel of the loader along the road and road berm, an inner boom disposed within the cylinder housing and capable of selective, slidable, reciprocable extension and retraction within the cylinder housing in a direction lateral to the longitudinal axis of the loader, and a blade secured to the distal end of the inner boom. The berm clearing attachment also includes a pivoting cylinder secured to the support framework for selectively raising and lowering the cylinder housing with respect to the surface of the road so that the blade can be raised or lowered to facilitate side dozing of dirt and debris.
摘要翻译： 用于可拆卸固定到道路清理车的护堤清理附件，例如推土机，平地机，高升降机，自卸车，拖拉机或滑移装载机，用于侧面或侧面打瞌睡，积聚了道路和道路上的污垢和碎屑 当车辆在道路和道路护堤上行驶时，相对于道路清理车辆的纵向轴线横向往复往复运动，并且远离导轨。 护堤清除附件包括可拆卸地固定到清扫车辆的前部的支撑框架，并且当与滑移装载机一起使用时，支撑框架可拆卸地固定到装载机的前安装板上。 护堤清除附件包括细长的气缸壳体，其安装到横向于沿着道路和道路护堤的装载机的行进轴线的支撑框架，设置在气缸壳体内的内部起重臂，并且能够选择性地，可滑动地，可往复地延伸和缩回 气缸壳体沿与装载机的纵向轴线横向的方向，以及固定到内部起重臂的远端的叶片。 护堤清除附件还包括固定到支撑框架上的枢转圆柱体，用于相对于道路的表面选择性地升高和降低气缸壳体，使得叶片可以升高或降低以便于灰尘和碎屑的侧面打瞌睡。
