Definitions

  • the present invention relates to shredders of the type used for shredding branches and other vegetation, typically garden waste.
  • EP1393616 we describe a feed inlet or hopper for a vegetation shredder.
  • the hopper has a generally rectangular opening having opposed walls, each of which includes a plurality of fingers projecting into the opening to direct vegetation into the hopper in a more vertical direction towards the cutter.
  • the present invention seeks to overcome this problem.
  • a feed inlet or hopper for a shredder apparatus having an opening between opposed first and second walls, wherein at least one of said first and second walls includes a plurality of projections extending substantially into the opening; characterised in that each of said projections includes inclined upper and lower surfaces and the inclined upper and lower projection surfaces combine to form a generally continuous arcuate projection surface.
  • the hopper comprises inner and outer hopper elements.
  • the inner hopper element is formed as a unitary element. More suitably, the inner hopper element is formed of a plastics material, suitably polypropylene.
  • the present invention also provides a shredder including a hopper as defined above.
  • a hopper 10 for a vegetation shredder is formed from two components, an outer hopper element 11, which may form part of, or be integral with, a shredder chute assembly or may attach to a shredder chute assembly, and an inner hopper element 12.
  • an outer hopper element 11 which may form part of, or be integral with, a shredder chute assembly or may attach to a shredder chute assembly
  • an inner hopper element 12 Other constructions are equally suitable.
  • the hopper 10 includes an outlet or lower aperture 13 ( Figure 3 ) in communication with a chute of a shredder, which chute leads to the cutting chamber.
  • the hopper has opposing major hopper walls 14, 15 and opposing minor hopper walls 16, 17.
  • major hopper walls include inclined upper surfaces such that the upper portion of hopper 10 has a greater area than that of aperture 13.
  • each projection Projecting from each of major walls 14, 15 are plurality of spaced projections or fingers 20.
  • Each projection has an inclined upper surface 21 and a oppositely inclined lower surface 22, such that the projections 20 act to direct vegetation, such as branches, through the space between the opposed projections 20 in either direction.
  • the inclined upper surface 21 and inclined lower surface 22 are formed together as a generally arcuate member providing a continuous surface.
  • FIG 4 shows a shredder 30 including the hopper 10 of Figure 1 mounted, in the embodiment shown, within an outer shredder inlet assembly 34.
  • the shredder comprises a shredder housing 31 housing a cutter chamber 32 having a cutter assembly.
  • the cutter assembly may be of any conventional construction.
  • the hopper 10 is detachable from the shredder housing 31 such that it can be moved away from the cutter chamber for storage and clearance purposes.
  • the shredder is supported above the ground by means of a frame 33.
  • the shredder inlet assembly 34 also provides a chute which spaces the hopper 10 and thus the user's fingers, from the cutter assembly.
  • the components of the hopper are manufactured by injection moulding of plastics materials.
  • the two-part construction of inner and outer hopper elements allows the manufacture of the inner element as a unitary element, for example, from polypropylene.
