Apparatus for fine pulverization of dry leaves and garden debris

摘要

An apparatus for finely pulverizing lawn debris has a central drive shaft driven by a gasoline or electrical power source. Lawn debris is drawn into a suction and grinding chamber by the rotation of a distribution plate which has a plurality of curved impeller blades permanently attached to a perforated plate. A grinding blade with a plurality of blade elements is mounted on the central drive shaft above the distribution plate and effects pulverization of the debris. The distributing plate apertures dispense the pulverized debris uniformly over a lawn. Optionally, additional fan impeller blades may be mounted on the central drive shaft to draw and initiate pulverization of the debris. In this case, the rotation of the distributing plate may be stopped by disengaging a clutch mounted on the central shaft to direct pulverized debris to a side collection chamber, which is periodically emptied through a bottom discharge gate.
