A silo having a conventional tubular construction including a plurality of openings in one sidewall thereof and covered by a U-shaped housing to form an access chute. Attached to the outside of this U-shaped housing is a second housing to form a discharge chute between the outside of the U-shaped housing and the inside of the second housing. Side openings are formed in the side of the U-shaped housing facing the discharge chute. A funnel is provided to receive the silage from the conventional silo unloader disposed within the silo, and direct it from the access chute, where it is propelled by the silo unloader, into the discharge chute, where it can fall to the bottom of the silo without silage buildup in the access chute. Doors are provided over the side openings which are biased toward the closed position and automatically forced and held open upon insertion of the funnel in the appropriate side openings. In one embodiment the second housing has a reverse J-shape and is placed alongside the first, and in that case the silo wall also encloses part of the discharge chute. In another embodiment the second housing is U-shaped and is attached outside the first chute on the side opposite the silo.
