Abstract
A debris-collecting apparatus includes a draft inducer operable to draw air and debris, an input portion for receiving incoming air and debris caused by operation of the draft inducer, and a bagging portion. The bagging portion includes a hood having an arcuate portion, a bag removably positioned below the hood and having an inner face, and a bagging passage for directing the air and debris from the input portion to the hood. The arcuate portion extends from the bagging passage to the bag such that the air and debris from the bagging passage travels along the arcuate portion and thereafter apply a dislodging force to dislodge debris collected at the inner face of the bag.
Claims19
A debris-collecting apparatus, comprising:
- a mobile frame;
- an input portion configured to receive incoming air and debris;
- and
- a bagging portion comprising:
- a hood having a spiral portion;
- an air permeable bag removably positioned below the hood, the air permeable bag having an inner face comprising a plurality of pores;
- a dust skirt surrounding the air permeable bag and configured to filter the air and debris passing through the air permeable bag;
- and
- a bagging passage for directing the air and debris from the input portion to the hood,
- wherein the spiral portion extends from the bagging passage to the air permeable bag such that the air and debris from the bagging passage travels along the spiral portion to induce a spiral flow of air and debris and thereafter apply a dislodging force to debris collected at the inner face of the air permeable bag.
A debris-collecting apparatus, comprising:
- a mobile frame;
- an input portion for receiving an incoming flow of air and debris;
- and
- a bagging portion comprising:
- a hood having a spiral portion, a first end, and a second end;
- an air permeable bag removably positioned below the hood, the air permeable bag having an inner face;
- a dust skirt surrounding the air permeable bag and configured to filter debris passing through the air permeable bag;
- and
- a bagging passage,
- wherein the bagging passage connects the input portion to the first end of the hood so that the flow of air and debris is directed from the input portion to the first end of the hood, and the spiral portion of the hood is configured to induce a spiral flow of air and debris from the second end of the hood to the air permeable bag to dislodge collected debris on the inner face of the air permeable bag.
