Debris-collecting apparatus and method of collecting debris

Abstract

A debris-collecting apparatus includes a mobile frame, an input portion configured to receive incoming air and debris, and a bagging system having a porous bag and a dust skirt surrounding the porous bag.

What is claimed is: 
     
         1 . A debris-collecting apparatus, comprising:
 a mobile frame;   an input portion configured to receive incoming air and debris; and   a bagging system including:
 a porous bag; and 
 a dust skirt surrounding the porous bag. 
   
     
     
         2 . The debris-collecting apparatus of  claim 1 , wherein the porous bag is formed from a different material than the dust skirt. 
     
     
         3 . The debris-collecting apparatus of  claim 1 , wherein the porous bag is removably coupled to the dust skirt by fasteners. 
     
     
         4 . The debris-collecting apparatus of  claim 1 , wherein the dust skirt includes a first layer and a second layer. 
     
     
         5 . The debris-collecting apparatus of  claim 4 , wherein the first layer of the dust skirt includes an inner face and an outer face. 
     
     
         6 . The debris-collecting apparatus of  claim 5 , wherein the inner face is electrically charged so that debris passing through the air permeable bag is attracted to the first layer. 
     
     
         7 . The debris-collecting apparatus of  claim 5 , wherein the outer face is not electrically charged. 
     
     
         8 . The debris-collecting apparatus of  claim 5 , wherein the outer face is coupled to the second layer by an adhesive. 
     
     
         9 . The debris-collecting apparatus of  claim 4 , wherein the first layer is coupled to the second layer by an adhesive. 
     
     
         10 . The debris-collecting apparatus of  claim 4 , wherein the first layer is formed from a different material than second layer. 
     
     
         11 . A debris-collecting apparatus, comprising:
 a mobile frame;   an input portion configured to receive incoming air and debris; and   a bagging system including:
 a dust skirt; and 
 an air permeable bag nested in a cavity of the dust skirt, wherein the dust skirt is removably coupled to the air permeable bag using fasteners, and wherein the dust skirt is formed by a first layer coupled to a second layer with an adhesive. 
   
     
     
         12 . The debris-collecting apparatus of  claim 11 , wherein the air permeable bag is formed from a different material than the dust skirt. 
     
     
         13 . The debris-collecting apparatus of  claim 11 , wherein the first layer of the dust skirt includes an inner face and an outer face. 
     
     
         14 . The debris-collecting apparatus of  claim 13 , wherein the inner face is electrically charged so that debris passing through the air permeable bag is attracted to the first layer. 
     
     
         15 . The debris-collecting apparatus of  claim 13 , wherein the outer face is not electrically charged. 
     
     
         16 . The debris-collecting apparatus of  claim 13 , wherein the outer face is coupled to the second layer by an adhesive. 
     
     
         17 . The debris-collecting apparatus of  claim 11 , wherein the first layer is formed from a different material than second layer. 
     
     
         18 . A debris-collecting apparatus, comprising:
 a mobile frame;   a filter;   an input portion configured to receive incoming air and debris; and   a bagging system including:
 an air permeable bag; and 
 a dust skirt located radially outward from the air permeable bag. 
   
     
     
         19 . The debris-collecting apparatus of  claim 18 , wherein the dust skirt includes a first layer and a second layer. 
     
     
         20 . The debris-collecting apparatus of  claim 19 , wherein the first layer is formed from a different material than second layer.
