ABSTRACT:
Silo unloading apparatus of the bottom unloading type is provided, wherein an auger is mounted for rotation on its own axis and for arcuate sweeping motion across the floor of the silo, conveying silage toward a central opening, and a single drive is provided for driving a central shaft that both rotates the auger about its own axis, and which rotates an intermediate mechanism that transfers relatively uniform rotational motion from the shaft into an intermittent rotational motion whereby a band located in the silo floor and spaced from the center of the silo is incrementally driven preferably by means of a toothed wheel, for incrementally sweeping the auger across the silo floor. The band is carried in a generally circular track in the floor of a silo and a cover for the opening into the track is provided, carried by the band for movement therewith. The auger is constructed to vary in pitch at different locations along its length, and to vary in flite depth along its length, and is constructed of different diameter stages. An exit auger is constructed to vary in flite depth and consequently in depth of bite, along its length as it conveys silage.
