ROTARY BRUSH SWEEPER ASSEMBLY

摘要

An improved sweeper assembly having a pair of oppositely rotatable brushes supported in spaced parallel relation within a housing enclosure. A lower baffle plate is provided forward of the lower brush which defines an expanding throat for the housing. Particulate material is swept by the lower brush, through the throat opening and then propelled by the upper brush out of the housing into a collection hopper. The lower baffle also includes a downwardly facing arcuate lower end, which is spaced below the rotational axis of the lower brush and which serves as a drag plate, limiting the material swept by the lower brush. The brushes are driven by rotation of the ground supporting wheels at predetermined speeds to improve the collection capacity of the sweeper assembly.
