ABSTRACT:
A device for the emptying of the residual product stored in a silo comprises a series of beams, for example, two or three beams. The first beam is mounted pivotably at a first end thereof on a pivot situated at the center of the discharge opening of the silo. Toward its second end, the first beam is articulated via a pivot to a first end of the second beam. If three beams are provided, the second end of the second beam is similarly articulated via a pivot to the first end of the third beam. Each beam supports a rotatable endless screw for feeding the product in the direction of the first end that beam and thus toward the discharge opening of the silo, and bears against the base of the silo via a drivable wheel which enables the beam to be pivotally displaced over the base of the silo. Each beam also carries a motor assembly for driving the endless screw and the wheel associated with that beam.
