Abstract

A sweeping broom apparatus comprises a main body having a debris receiving inlet, and connecting arms for operatively connecting the main body to a vehicle. A broom shroud has a forwardly facing debris outlet for permitting the directed egress of debris therefrom as a forwardly propelled stream of debris. There are arms for mounting the broom shroud on the main body, for free vertical movement of the broom shroud with respect to the main body. A main sweeping broom is operatively mounted free vertical movement within the broom shroud for propelling debris forwardly from a surface being cleaned, thereby creating a stream of debris propelled forwardly through the forwardly facing debris outlet to a the debris receiving inlet of the vehicle. A dust-containing pliable cover is connected in substantially sealed relation to the broom shroud at the forwardly facing debris outlet and connected in substantially sealed relation to the vehicle at the debris receiving inlet for containing dust from the stream of debris propelled forwardly through the forwardly facing debris outlet.

Description

[0001] This application is a non-provisional application claiming priority from U.S. Provisional Patent Application Ser. No. 60 / 975,029 filed on Sep. 25, 2007, which is herein incorporated by reference.FIELD OF THE INVENTION

[0002] The present invention relates to street sweeping vehicles, and more particularly to dustless street sweeping vehicles.BACKGROUND OF THE INVENTION

[0003] Conventional street sweepers have a main vehicle body and a hopper supported by the main vehicle body. In mechanical type street sweepers, there is a debris elevator at the back end of the vehicle. A large cylindrically shaped rotating sweeping broom is disposed immediately behind the elevator. The large cylindrically shaped sweeping broom contacts the surface being cleaned so as to propel debris forwardly to the elevator. The debris elevator receives debris from a main sweeping broom and deposits the debris into the hopper.

[0004] Similarly, for re-circulating types street sweepers and vacuum type street sweepe...
