ABSTRACT:
An apparatus for unloading a silo having side walls and a floor which includes a central chute that supplies material to a conveyor box which is covered except for the chute. A conveyor in the conveyor box conveys material from the central chute out through a material outlet in the silo. The central positioning of the chute causes a top surface of the remaining material in the silo to form itself into a conical shape having an apex moving toward the central chute. As the material is depleted to such an extent that the apex of the material surface meets the central chute, the remainder of the material is blown to a lower run of the conveyor and discharged from the floor of the silo.
