Abstract
A materials processing unit incorporating three stage processing. The material to be processed is passed through a breaker unit (19) which breaks the material down to a consistent size for processing by a pulverizer unit (20) which further breaks down the material before it is transferred to a container (13) for compacting by ram (27) and blade (28). The material may be transferred to the container (13) by auger screws (25, 26) or a vacuum system comprising a fan (34) for reducing the pressure within the container (13) and causing the material to be sucked through duct (40) into the container (13). The unit may be mounted on a wheeled vehicle (12) and used to process a variety of materials from garbage to fruit.
Claims9
A materials processing unit comprising:
- a container having an outlet doorway at one end,
- a door closable on said doorway,
- an inway opening in said container for admission of material to be stored in said container,
- a breaker unit including a casing having an inlet to admit material to be broken to said casing, and an outlet to permit discharge of broken material from said casing, said breaker unit comprising a drum mounted for rotation about a first axis and having fixedly mounted thereon a plurality of radially protruding cogs adapted to crush material entering the unit against said breaker casing during rotation of said drum, said drum being mounted transverse of said breaker unit inlet so that material entering therethrough approaches said cogs radially thereof,
- a pulveriser unit mounted for rotation about a second axis below said breaker unit and including a further casing having an inlet to admit material processed by said breaker unit and an outlet to permit discharge of pulverised material from said further casing, said pulveriser casing including a pair of end walls, the inlet thereof comprising an aperture adjacent one of said end walls, and the outlet thereof comprising a duct in a portion of the other of said end walls,
- said breaker unit having its outlet connected to the inlet of the pulveriser unit by a chute positioned below the breaker unit and to one side of the pulveriser unit, said first and second axes being angularly related so that said chute provides a collection area for output material from the breaker unit and prevents blow-back of material from the pulveriser unit into the breaker unit,
- an open-ended hopper mounted by one end on the inlet to said breaker casing and having its other end positioned to accept material to be processed by said vehicle,
- transfer means whereby material discharged from said pulveriser outlet is transferred to said inway opening to fall therefrom into said container.

A materials processing vehicle incorporating a wheeled frame, and comprising:
- (a) a container mounted on said frame and having an outlet doorway at its trailing end,
- (b) a door closable on said doorway,
- (c) an inway opening in said container for admission of material to be stored in said container,
- (d) a breaker unit mounted on said frame and including a casing having an inlet to admit material to be broken to said casing, and an outlet to permit discharge of broken material from said casing, said breaker unit comprising a drum mounted for rotation about a first axis and having fixedly mounted thereon a plurality of radially protruding cogs adapted to crush material entering the unit against said breaker casing during rotation of said drum, said drum being mounted transverse of said breaker unit inlet so that material entering therethrough approaches said cogs radially thereof,
- (e) a pulveriser unit mounted for rotation on a second axis on said frame below said breaker unit and including a further casing having an inlet to admit material processed by said breaker unit and an outlet to permit discharge of pulverised material from said further casing, said pulveriser casing including a pair of end walls, the inlet thereof comprising an aperture adjacent one of said end walls, and the outlet thereof comprising a duct in a portion of the other of said end walls,
- said breaker unit having its outlet connected to the inlet of the pulveriser unit by a chute positioned below the breaker unit and to one side of the pulveriser unit, said first and second axes being angularly related so that said chute provides a collection area for output material from the breaker unit and prevents blow-back of material from the pulveriser unit into the breaker unit,
- (f) an open-ended hopper mounted by one end on the inlet to said breaker casing and having its other end positioned to accept material to be processed by said vehicle,
- (g) transfer means whereby material discharged from said pulveriser outlet is transferred to said inway opening to fall therefrom into said container.
