Mobile shredding system

Abstract

Disclosed is a mobile shredding and material handling and feed system, preferably for use in the handling and shredding of paper and other office related feedstock. An embodiment of the system on the input side utilizes an input hopper, a first conveyor, a feed aperture, and a second conveyor which moves excess feedstock away from the entry to the shredder feed aperture to avoid jamming the feed aperture. An embodiment of the invention on the output side utilizes a compactor, preferably one or more augers, to compact the shredded material exiting the shredder, and moving said compacted shredded material to the discharge or system output. An embodiment of this material handling and feed system also applies for balers.

       3. A mobile shredding system as recited in  claim 2 , and wherein the compactor is one or more augers. 
     
     
       4. A mobile shredding system as recited in  claim 1 , and which further comprises a shredder feed drum rotatably mounted between the shredder feed aperture and the shredder, wherein rotation of the shredder feed drum pulls feedstock from the feed aperture and pushes it toward the shredder. 
     
     
       5. A mobile shredding system as recited in  claim 1 , and wherein the first conveyor is in a substantially horizontal orientation. 
     
     
       6. A mobile shredding system as recited in  claim 1 , and wherein the second conveyor is in a substantially vertical orientation. 
     
     
       7. A shredded system, comprising:
 ( a )  an input hopper with a hopper inlet and a hopper outlet, the hopper disposed to receive feedstock to be shredded;      ( b )  a first conveyor with a first conveyor inlet and a first conveyor outlet, the first conveyor inlet disposed to receive feedstock from the hopper outlet;      ( c )  a shredder feed aperture disposed to receive feedstock from the first conveyor outlet;      ( d )  a second conveyor with a second conveyor inlet disposed to receive excess feedstock from the first conveyor outlet, the second conveyor having a conveyor surface moving away from the shredder feed aperture, wherein the second conveyor moves excess feedstock away from the shredder feed aperture; and      ( e )  a shredder disposed to receive feedstock from the feed aperture, the shredder having a shredder inlet and a shredder outlet.     
     
     
       8. A shredding system as recited in  claim 7 , and which further comprises:
   a shredded material compactor disposed to receive shredded material from the shredder outlet, the shredded material compactor having a compactor outlet;        a reciprocating ram, with a stroke of the reciprocating ram defining a discharge area, the discharge area disposed to receive shredded stock from the shredded material compactor, the discharge area having an outlet.     
     
     
       9. A shredding system as recited in  claim 8 , and wherein the compactor is one or more augers. 
     
     
       10. A shredding system as recited in  claim 7 , and which further comprises a shredder feed drum rotatably mounted between the shredder feed aperture and the shredder, wherein rotation of the shredder feed drum pulls feedstock from the feed aperture and pushes it toward the shredder. 
     
     
       11. A shredding system as recited in  claim 7 , and wherein the first conveyor is in a substantially horizontal orientation. 
     
     
       12. A shredding system as recited in  claim 7 , and wherein the second conveyor is in a substantially vertical orientation. 
     
     
       13. A feedstock feed system, comprising:
 ( a )  an input hopper with a hopper inlet and a hopper outlet, the hopper disposed to receive feedstock;      ( b )  a first conveyor with a first conveyor inlet and a first conveyor outlet, the first conveyor inlet disposed to receive feedstock from the hopper outlet;      ( c )  a feed aperture disposed to receive feedstock from the first conveyor outlet; and      ( d )  a second conveyor with a second conveyor inlet disposed to receive excess feedstock from the first conveyor outlet, the second conveyor having a conveyor surface moving away from the feed aperture, wherein the second conveyor moves excess feedstock away from the feed aperture;        a shredder disposed to receive feedstock from the feed aperture, the shredder having a shredder inlet and a shredder outlet; and        wherein the first conveyor is a belt conveyor.     
     
     
       14. A feedstock feed system as recited in  claim 13 , and which further comprises:
   a shredded material compactor disposed to receive shredded material from a shredder outlet, the shredded material compactor having a compactor outlet;        a reciprocating ram, with a stroke of the reciprocating ram defining a discharge area, the discharge area disposed to receive shredded stock from the shredded material compactor, the discharge area having an outlet.
