Abstract
A comminuting mechanism is disclosed that includes a rotatable drive shaft which supports a plurality of blades, each blade having both straight arms and arms having angled tip portions. The shaft and blades are supported on a frame within a hood, and the frame is pulled along a ground surface by a tractor or other vehicle. Debris is pulled into the housing by the combined action of the forward motion of the vehicle and an inward airflow generated by fan members on the rotating blades, pulverized by the action of the blades, and discharged through an outlet.

A comminuting machine for pulverizing ground debris, comprising:
- a mobile support structure movable along a path of travel on a ground surface;
- a drive shaft supported by said mobile support structure transversely of said path of travel;
- means for rotating said drive shaft, said means secured on said mobile support structure;
- a plurality of blades mounted on said drive shaft for axial rotation therewith;
- a mouth for collecting ground debris disposed frontwardly of said blades, adjacent the ground;
- a discharge for comminuted debris disposed rearwardly of said blades;
- a plate disposed generally beneath said blades extending from the mouth at a front portion of the plate to the discharge at a rear portion of the plate, the plate being angled upwardly toward the discharge at the rear portion thereof;
- and
- an arcuate hood coextensive with the length of said drive shaft in an outwardly spaced relation thereto to define an arcuate air chamber extending from the mouth over the blades to the discharge, said air chamber and said airflow generating elements serving to enhance collection of ground debris and discharge of pulverized ground debris.
A comminuting mechanism, comprising:
- a mobile support structure movable along a path of travel on a ground surface;
- a drive shaft laterally supported by said mobile support structure transversely of said path of travel;
- means for rotating said drive shaft, said means secured on said mobile support structure;
- a plurality of pulverizing blades each having an axial bore for mounting said pulverizing blades on said drive shaft, each of said pulverizing blades comprising a plurality of straight extending arms alternately disposed with respect to a plurality of inwardly deflected arms and a plurality of outwardly deflected arms;
- an arcuate hood coextensive with the length of said drive shaft in an outwardly spaced relation thereto;
- a mouth for collecting ground debris disposed forwardly of said blades, adjacent the ground;
- a discharge for comminuted debris disposed rearwardly of said blades;
- a plate disposed generally beneath said blades extending from the mouth at a front portion of the plate to the discharge at a rear portion of the plate, the plate being angled upwardly toward the discharge at the rear portion thereof;
- and
- a base having a debris receiving opening extending axially along said rotatable shaft, said base secured to said mobile support structure, said debris receiving opening being configured to receive ground debris along said path of travel substantially at the ground level surface whereby, upon rotation of said shaft, said received ground debris is pulverized by the rotation of said plurality of pulverizing blades and discharged through an outlet opening.
