ABSTRACT:
Motor-driven shredding apparatus for garden waste consists of a cutter support plate (13) rotating about a vertical axis in a cutter housing (4) provided with an outlet channel (4"), which plate (13) includes outlet slots (13') and plane-blade-like shredding cutters (14) thereabove. Above the cutter housing (4), two inlets (1,2) are provided for the separate supply of light and heavy material to be shredded, such as thin twigs and leaves and thicker twigs and branches respectively, wherein the inlet (2) for the heavy material to be shredded extends to the shredding cutters (14) and the other inlet (1) lies above shredding blades (17) rotating with the cutter support plate (13). In order to achieve a more effective shredding and blockage-free discharge even of light material to be shredded with a lower power rating, the shredding blades (17) are secured centrally to the upper side of the cutter support plate (13) and project into the lower end of a charging container (3) arranged over the cutter housing (4) and provided with fixed counter-plates (8), which container (3) carries at the top the inlet (1) for the light material to be shredded and below is closed by the cutter support plate (13) and also is equipped with the other, inclined inlet (2) formed as the inlet tube for branches.
