Abstract
A shredder blade assembly includes a rotor having a plurality of pockets. The shredder blade assembly further includes a plurality of knife blades which are each disposed in one of the plurality of pockets. The knife blades are secured into the pockets by a compression force applied from a periphery of the rotor and in a direction towards a shaft aperture in the rotor.
Claims15
A shredder blade assembly, comprising:
- a rotor having a plurality of pockets, the plurality of pockets being disposed on both sides of the rotor such that pockets on opposing sides of the rotor are aligned, each one of the plurality of pockets including a rotor aperture;
- a detent screw having an outdented end;
- a plurality of knife blades sized to fit the shape of the plurality of pockets, each one of the plurality of knife blades including three discrete cutting edges spaced around a periphery of the knife blade;
- a pin, the pin receiving a compression force from a periphery of the rotor by contact from the outdented end of the detent screw in a detent of the pin, the pin extending through two of the plurality of knife blades on the rotor and through the rotor aperture;
- and
- wherein each of the plurality of knife blades is disposed in one of the plurality of pockets and secured into the pockets by the compression force applied from the detent screw from the periphery of the rotor and in a direction towards a shaft aperture in the rotor, the pin positioned within the rotor aperture transfers the compression force from the detent screw from the periphery of the rotor to the plurality of knife blades to secure the two of the plurality of knife blades in two of the plurality of pockets,
- wherein the two of the plurality of knife blades are placed on opposing sides of the rotor and are each secured in individual pockets, on opposing sides of the rotor, by the same compression force that is applied from the periphery of the rotor transferred through the pin, wherein the detent screw is disposed in the periphery of the rotor directly between the two of the plurality of knife blades and at a midpoint between the opposing sides of the rotor.

A shredder blade rotor, comprising:
- a rotor body comprising a plurality of pockets, the plurality of pockets being disposed on both sides of the rotor such that pockets on opposing sides of the rotor are aligned;
- a plurality of rotor apertures singularly disposed on an inside surface of each of the plurality of pockets;
- and
- a plurality of detent screw holes each disposed in a periphery of the rotor body and extending through the rotor to one of the plurality of rotor apertures, the plurality of detent screw holes each receiving a head of a detent screw such that the head of each detent screw is disposed within the rotor,
- wherein two of a plurality of knife blades, which both include three discrete cutting edges spaced around a periphery of each of the two of the plurality of knife blades are sized to fit the shape of the plurality of pockets;
- wherein each of the plurality of knife blades are placed on opposite sides of the rotor and are secured in individual pockets, on opposite sides of the rotor, by a compression force applied by the detent screws disposed in the plurality of detent screw holes from the periphery of the rotor, the compression force pressing the two of the plurality of knife blades towards a shaft aperture in the rotor and securing the two of the plurality of knife blades in two of the plurality of pockets, wherein each of the plurality of detent screw holes is disposed in the periphery of the rotor directly between two of the plurality of knife blades placed on opposite sides of the rotor body and at a midpoint between the two opposite sides of the rotor.

A shredder blade assembly, comprising:
- a plurality of knife blades having three discrete cutting edges spaced around a periphery of the knife blade, the plurality of knife blades being disposed on opposing sides of a rotor such that each knife blade of the plurality of knife blades is aligned with one of the plurality of knife blades on the opposing side of the rotor, wherein first knife blade, among the plurality of knife blades, is disposed on one side of the rotor and is connected to a second knife blade, among the plurality of knife blades, on the opposing side of the rotor, relative to the first knife blade, by a single pin extending through a rotor aperture,
- wherein the pin transfers a compression force from a periphery of the rotor to secure the first knife blade and second knife blade into individual pockets in the rotor;
- and
- a detent screw hole which receives a head of a detent screw such that the head of the detent screw is disposed within the rotor, the detent screw hole extending from the periphery of the rotor to the rotor aperture, wherein the detent screw hole is disposed in the periphery of the rotor directly between the first knife blade and the second knife blade and at a midpoint between the two opposing sides of the rotor.
