ABSTRACT:
An overhead silo filling device for uniformly distributing ensilage and particulate materials in substantially symmetrical concentric fashion around a central axis of silos and the like comprises a hollow chamber with a discharge outlet at the lower end and adapted to be centered above the surface of the material in the silo. The chamber is supported in an opening in the silo roof structure and includes an upper section, an inwardly and downwardly sloping frusto-conical intermediate section and a lower discharge section which forms the discharge outlet for dispensing silage at the lower end. A material inlet conduit is secured to the upper section of the chamber for directing an inflow of material against an inside wall surface, and the inlet conduit slopes upwardly away from the upper section so that the material is directed downwardly into the chamber to form a downwardly spiralling path inside the chamber wall moving toward the discharge outlet. Air vent means is provided for exhausting air from the chamber to the atmosphere and a valve is provided to open and close for controlling the flow of air and/or material between the discharge outlet and the interior of the silo, and to seal the silo at the upper end from the external atmosphere.
