APPARATUSES, SYSTEMS, AND METHODS FOR CLEARING A SURFACE USING PRESSURIZED AIR

摘要

Provided are apparatuses, methods, and systems to clear a road surface of debris, water, or other contaminants. A system for clearing a road surface is provided including an air knife with an elongate orifice extending along a line, a frame configured to support the air knife in a position substantially parallel to a plane defined by the road surface, and a tow bar coupled to the frame, where the tow bar is pivotable relative to the frame along an axis orthogonal to the plane defined by the road surface. The system may include a mounting plate connected to the tow bar, where the mounting plate is pivotably mounted to the frame. The air knife may be supplied with pressurized air to clear the road surface of debris. A guide wheel may be attached to the frame, where the guide wheel is configured to rotate about an axis orthogonal to the plane defined by the road surface.

主权项

1. A system for clearing a surface, the system comprising:
a first air knife assembly extending longitudinally between a first end and a second end; a second air knife assembly extending longitudinally between a first end and a second end; wherein the second end of the first air knife assembly is pivotably attached to the first end of the second air knife assembly, wherein the first air knife assembly is configured to pivot relative to the second air knife assembly about the pivotable attachment along a first axis substantially perpendicular to the longitudinal extension of at least one of the first air knife assembly and the second air knife assembly.
