Street sweeper with vacuumized dust control

Abstract

A street sweeper with vacuumized dust control where a rotary broom chamber surrounds a rotary broom. The rotary broom chamber connects by a conveyor housing containing a conveyor mechanism to a hopper having a powered fan and a filter. A vacuum or low pressure is created within the hopper which communicates through the conveyor housing to the rotary broom chamber which creates an airflow therebetween which carries dust or other light debris to a filter which filters out the dust particles or other light debris. The conveyor housing and other components are positionable to accommodate various modes of operation.

Description

CROSS REFERENCES TO RELATED APPLICATIONS [0001] None. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention is for a street cleaning device, and, more particularly, pertains to a street sweeper with vacuumized dust control. [0004] 2. Description of the Prior Art [0005] Prior art street sweeper devices are often built on and about custom chassis not generally suited for economy of speed or having attributes geared toward desirable roadability qualities. Often such street sweepers include rotary sweeper brooms placed between the front wheel assemblies and special rear wheel drive or axle assemblies beneath a configured framework in an area often otherwise reserved for drive shafts and other framework members in conventional chassis, such as used for conventional trucks. Street sweepers utilizing truck chassis are also used for mounting of street sweeper components and are utilized for greater roadability and transport speed suitable for highway use....

AI Technical Summary

Benefits of technology

[0019] Having thus described embodiments of the present invention and enumerated several significant aspects and features thereof, it is the principal object of the present invention to provide a street sweeper which features, in part, vacuumized dust control.

Problems solved by technology

Prior art street sweeper devices are often built on and about custom chassis not generally suited for economy of speed or having attributes geared toward desirable roadability qualities.

Some arrangements, such as rotary broom placement between the front wheel and rear wheel assemblies, are often limited, necessitating the use of smaller rotary brooms the dimensions of which are restricted by the available distance between the roadway and the chassis of the conventional truck.

The use of water is not always economical, water may not be readily available for dust control, large water flow may be required for effective dust control, thereby necessitating frequent refilling stops due to limited tank capacity, and the use of water at higher speeds may not be effective.
