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 ring gear located beneath the center of the silo and which carries the mount for the auger, may be engaged by push-pull mechanisms that function as force or torque multipliers. The ring gear, upon being engaged and moved, caused the incremental sweeping motion of the auger across the floor. A manual adjustment is provided for interrupting the advancing motion of the auger, if desired. A switch mechanism disposed in a hopper beneath the auger, which switch is sensitive to the presence or absence of silage therein, and can actuate the single motor that drives the central shaft, when the hopper is sufficiently empty to accommodate the receipt of additional silage therein.
