Abstract: In order in the case of a chopper for waste material and more particularly for garden waste, comprising a feed hopper and a roller-like cutting rotor arranged at a lower end of the hopper and adapted to be driven for cooperation with a stationary mating knife arrangement, to achieve quiet operation in a manner which makes the chopper easy to use and provides for a long working life, the roller-like cutting rotor is constituted by a roller-like cutting rotor whose axis extends transversely in relation to the axis of the hopper, and which bears circumferential teeth between which gaps are provided, which during operation are cleared by a clearing spud adapted to plunge into them.

Abstract: In the context of a device for chopping up garden waste or the like of the type comprising a housing mounted on support legs and having at least one ejector opening, a preferably vertical charging passage mounted on the housing, a carrier disk adapted to rotate in the housing about an upright axis and mounted on the shaft of a motor attached to the housing so that the disk shuts off the housing at a lower end thereof and at least one generally radially aligned knife on the disk which is placed on a trailing edge, i.e.

Abstract: A device for chopping up refuse comprises a generally uncovered, level base plate, legs fixed at top ends thereof to the base plate, and a support disk adapted to turn about an upright axis. This disk is placed under the base plate and has at least one slot therein. A knife is fixed on the disk and placed to the back of the slot in the direction of turning of the disk, the knife having a cutting edge placed at a higher level than the top face of the disk. There is furthermore an electric motor with a drive shaft for driving the disk. The base plate functions as a support frame for the device. A filling passageway is supported on top of the base plate next to the motor that is also supported on the plate, and there is furthermore an upright and downwardly open ejection passageway fixed on a lower side of the base plate and coaxially placed around disk, that is fixed on the motor drive shaft.
