FEED STORAGE Russian patent published in 1997 - IPC

FIELD: agriculture, in particular, storing of feeds in tower- type storages. SUBSTANCE: storage has cylindrical vessel with cupola, hollow column aligned with storage axis, feeder, vertical discharge conveyor mounted within hollow column, shaft mounted on column, drive mechanism formed as winch adapted for longitudinal displacement on shaft. Working tool formed as conveyor is pivotally connected with shaft. Conveyor has rakes and feed compactor driven by running wheels. Cupola is formed from metal plates supported by storage wall. Supporting ring is mounted on hollow column. Cupola is made from two spherical layers. Upper layer has curvature center coinciding with storage axis. Lower spherical layer has plates with curvature increasing as curvature center is shifting from storage axis for distance equal to radius of supporting ring of upper spherical layer. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 7 dwg
