Patent ID: 6981831

Claim:
A device for distributing bulk materials comprising: a support frame; a distribution chute for the bulk materials; a suspension rotor mounted in said support frame so as to be capable of rotating about a substantially vertical axis of rotation, said chute being suspended to said suspension rotor so as to be tiltable about a substantially horizontal tilt axis; a first motor able to rotate said suspension rotor about its axis of rotation in a first direction; a tilt controlling rotor mounted in said support frame so that it is capable of rotating about a substantially vertical axis of rotation; and a tilting mechanism connected between said chute and said tilt controlling rotor, said tilting mechanism being designed in order to transform a differential rotation of said suspension rotor and of said tilt controlling rotor into a variation of the angle of inclination of said chute between two extreme positions, wherein said chute is balanced so that it returns to a first of said two extreme positions, while accelerating said tilt controlling rotor via said tilting mechanism in the direction of rotation of said suspension rotor; a first braking device associated with said tilt controlling rotor so that it is capable of exerting a braking moment on said tilt controlling rotor; and a first control device associated with said first braking device in order to control the variation of the angle of inclination of said chute by controlled braking of said tilt controlling rotor.
