Abstract
A waste collecting/removal apparatus having a bin with a forward waste outlet opening, a rearward air flow inlet, a plurality of adjustable inclined louvres spaced from the bottom of the bin and an air flow plenum below the louvres to cause air flow between the louvres to move the waste material in the bin upwardly and forwardly toward the outlet opening.
Claims22
