US 6,983,904 B2 · Guillotine shears

Abstract

The invention discloses an impact shears having a rotor with individual chopping blades disposed on the rotor in a predetermined arrangement and with blade(s) or blade system that is generally stationary vis-à-vis the rotation of the rotor. The blade is held in a blade holder on the stator side of the rotor. The blade holder is movable on the stator about an axis parallel to the rotational axis of the rotor and carries at least two blades, or blade systems, that are expediently disposed at the same angular distance to one another. The blade holder can be rotated about an axis that extends parallel to the rotational axis of the rotor so that every blade of the blade holder can be brought in a cutting position to interact with the chopping blades of the rotor and can be locked in position with respect to the chopping blades.

Dependent claims

An impact shears comprising:

a rotor equipped with individual chopping blades in a predetermined configuration and a stator, said rotor having an axis of rotation;
at least two blades removably attached in a blade holder;
the blade holder located on the stator side of the rotor and being fundamentally stationary relative to the rotational movement of the rotor;
the blades being usefully disposed at an equal angular distance with respect to one another on the blade holder,
the blade holder is rotatable about an axis extending parallel to the rotational axis of rotor such that each blade of the blade holder can individually be brought into a cutting position cooperating with the chopping blades of the rotor;
and
the blade holder can be secured in position with respect to the cooperation of each blade with the chopping blades of the rotor.
