Silo structure

 A storage silo, for agricultural products and the like is provided, particularly adapted for use with silos of the bottom unloader type, and which are filled through a fill pipe extending from about ground level, to the upper end of the silo. A particularly unique connection is provided between the top and bottom of the silo, for substantially eliminating a pressure differential between the top and bottom that could otherwise have adverse affects on the silage upon filling at the side. The interconnection between the top and the bottom is through the silo fill pipe, and a vent line, and additionally may be provided for including silage gas bags in common interconnection with the fill pipe.

The bottom end of the fill pipe is telescopically extendable for attachment to a silage blower, and a closure for the bottom end of the fill pipe is adapted to sealingly close the fill pipe with the telescopically extendable member within the fill pipe. Additionally, the discharge at the upper end of the fill pipe is toward the center of the silo, and the fill pipe extends into the silo an amount at least as far as the vent opening in the roof. A drip sheet, terminating in a downwardly sloped drip edge, spaced outwardly from the upper end of the silo, but circumferentially around the silo, is provided, for discharging rain and the like away from the silo wall to eliminate staining
