Abstract
A device for distributing bulk materials includes a suspension rotor is mounted in a support frame which is capable of rotating about a substantially vertical axis of rotation. A chute is suspended to the suspension rotor and is tiltable about a substantially horizontal tilt axis. A first motor is capable of rotating the suspension rotor about its axis of rotation in a first direction, and a tilt controlling motor mounted in the support frame is capable of rotating about a substantially vertical axis of rotation. A tilting mechanism is also connected between the chute and the tilt controlling rotor, while a first braking device exerts a braking moment on the tilt controlling motor. A first control device controls the angle of inclination of the chute by controlled braking of the tilt controlling rotor.
