Debris-plowing pick-up head for a mobile sweeper

Abstract

A debris-plowing pick-up head for a mobile sweeper comprises a housing defining a substantially hollow interior and having a front, a back, a left end and a right end, a top and a bottom, and a suctioning bottom opening for suctioning dust and small debris into the substantially hollow interior of the housing. A suctioning front opening is disposed in the front of the housing for receiving debris into the substantially hollow interior of the housing. A selectively openable and closable door means operatively mounted on the debris plowing pick-up head for selectively opening and closing the suctioning front opening. There is a dust and debris outlet in the housing for permitting dust and debris to be suctioned from the substantially hollow interior of the housing into a hopper. A barrier is disposed on the top of the housing for substantially precluding the passage of large debris over the housing.

Description

[0001]This application is a non-provisional application claiming priority from U.S. Provisional Patent Application Ser. No. 60 / 975,052 filed on Sep. 25, 2007, which is herein incorporated by reference.FIELD OF THE INVENTION[0002]The present invention relates to factory and sidewalk sweepers, and more particularly to pick-up heads for factory and sidewalk sweepers.BACKGROUND OF THE INVENTION[0003]Sidewalk sweepers and factory floor sweepers of various types are used to sweep debris in many different types of locations. Sidewalk sweepers are typically used to sweep dust, dirt and debris from sidewalks, parking lots, and so on. Often, the dust, dirt and debris has accumulated significantly on a surface that is to be swept, and when swept by a sidewalk sweeper, the dust, dirt and debris can accumulate in front of a pick-up head or gutter broom high enough that the dust, dirt and debris actually travel over the pickup head or gutter broom. Accordingly, this dust, dirt and debris again en...

AI Technical Summary

Benefits of technology

"The present invention is about a new pick-up head for a mobile sweeper that can plow debris. It has a housing with a suctioning bottom opening for collecting dust and small debris. There is also a dust and debris outlet for removing the collected material into a hopper. The pick-up head has a barrier on the top to prevent large debris from passing through. The technical effect of this invention is to provide an efficient and effective tool for removing debris from various surfaces."

Problems solved by technology

Accordingly, this dust, dirt and debris again end up on the surface being swept, which is completely unacceptable.

Unfortunately, the lower outer ends of the pick-up heads tends to permit debris to readily pass over the outer end portions of the pickup head, which is unacceptable.
