  • Road/pavement cleaning machine having air-blast functionality
    Patent number: 7621018
    Abstract: A road/pavement sweeper is provided with a pickup head or debris-intake hood that operates in a conventional manner to entrain or aspirate particles and/or debris from the pavement surface. The air-inlet structure of the debris-intake hood is provided with an air-flow control member that selectively directs the air flow through the debris-intake hood in order to conventionally entrain debris or particles from the surface being swept or through an opening in the side of the air-inlet structure to create an air blast useful to blow debris from the pavement or roadway surface. One or more fixed-position or controlled-position air flow vanes can be provided to selectively direct the air blast.
