Abstract
A comminuting apparatus for garden waste consists of a cutter support plate rotating about a vertical axis in a cutter housing provided with a laterally directed outlet channel. The support plate includes cutting slots and slicing cutters thereabove. The support plate further includes at least one dependent discharge blade located on the underside thereof. At least one spiral deflecting vane is mounted on the cutter housing beneath the support plate. Upon rotation of the cutter support, the cutting slots and slicing cutters cooperate to direct comminuted material downwardly through the support plate, while the dependent discharge blade and the spiral deflecting vane cooperate to force comminuted material out through the laterally directed outlet channel.
Claims26
A machine for comminuting material comprising:
- a cutter housing having a laterally-directed outlet for the discharge from the machine of comminuted material;
- a cutter support plate mounted within the cutter housing for rotation about a central substantially vertical axis, said cutter support plate provided with at least one dependent discharge blade located on the lower side of said plate;
- at least one spiral deflecting vane means mounted on the cutter housing beneath said cutter support plate for cooperating with said at least one dependent discharge blade upon rotation of the cutter support plate to force comminuted waste through the laterally-directed outlet;
- at least one non-radial cutting slot in the cutter support plate, a slicing cutter mounted upon the cutter support plate above each non-radial cutting slot and cooperating therewith on rotation of the cutter support plate to slice waste material and direct the comminuted waste material downwardly through the cutter support plate;
- a charging container having a substantially vertical axis and walls for receiving waste material to be comminuted located over the cutter housing, the cutter support plate being positioned so as to form a base for the container;
- at least one shredding blade mounted on the upper side of the cutter support plate for rotation therewith and extending upwardly and outwardly from said central substantially vertical axis into the charging container;
- an inlet for light material to be comminuted located at the top of the container;
- an inlet for heavy material to be comminuted comprising a downwardly inclined inlet tube passing through a lower wall of the container to discharge above the cutter support plate in the path of rotation of said at least one slicing cutter;
- and
- a fixed counter-plate means located substantially diametrically opposite said inlet for heavy material, comprising an upper section sloping downwardly in the direction of rotation of said cutter plate and a lower section of substantially vertical orientation, said counter-plate means positioned so that the path of rotation of each slicing cutter is below and adjacent said counter-plate and so that the path of rotation of each shredding blade is above and adjacent said counter-plate, said counter-plate means cooperating with each shredding blade to produce shear action on waste material therebetween.

In a garden waste comminuting apparatus comprising a cutter housing having a laterally-directed discharge outlet;
- a cutter support plate mounted within the cutter housing for unidirectional rotation about a central vertical axis;
- at least one dependent discharge blade located on the lower side of said plate;
- at least one slot in the cutter support plate with a cutting blade mounted thereabove;
- a cylindrical charging container located over the cutter housing, the cutter support plate forming a base for the container;
- at least one shredding blade mounted centrally on the upper side of the cutter support plate and extending upwardly and outwardly therefrom into the charging container, an inlet for light material at the top of the container, an inlet for heavy material discharging above the cutter support plate;
- at least one fixed counter-plate located above the path of rotation of said cutting blade and below the path of rotation of said shredding blade;
- the improvement comprising at least one spiral deflecting vane means mounted on the cutter housing beneath said cutter support plate for cooperation with said at least one dependent discharge blade to force comminuted waste into the laterally-directed outlet upon rotation of the cutter support plate.

A shredder-mulcher for comminuting garden waste material comprising:
- first blade means for slicing heavy material into comminuted form;
- second blade means for shredding light material into comminuted form;
- means for rotating said first blade means and said second blade means about a central substantially vertical axis, the path of rotation of said first blade means lying in a plane perpendicular to said central substantially vertical axis and the path of rotation of said second blade means lying above that of the first blade means and extending upwardly and outwardly from said central vertical axis;
- first deflecting means for deflecting waste material in a downward direction, located between the paths of rotation of said first blade means and said second blade means, said first deflecting means cooperating with said second blade means to produce a shearing action therewith;
- a first inlet means for feeding heavy material into the path of rotation of said first blade means;
- a second inlet means for feeding light material into the path of rotation of said second blade means from above;
- discharge means for imparting kinetic energy to comminuted material, said discharge means located beneath the path of rotation of said first blade means;
- second deflection means for preventing comminuted material from clogging said discharge means and cooperating with said discharge means to force comminuted material in a direction orthogonal to said central vertical axis;
- and
- third deflection means for deflecting waste material in a downward direction, located between said second inlet and the path of rotation of said second blade means.
