ABSTRACT OF THE DISCLOSURE: Apparatus for use in loading and unloading a circular silo, comprising a conveyor duct, a material-handling blower associated with the duct, a horizontal conveyor screw which has an inner end associated with the lower end of the duct and is angularly movable about a main vertical axis extending near said inner end, at least two backing rollers which are rotatable on vertical axes and movable in unison with said conveyor screw about said main vertical axis and are engageable with the inside peripheral surface of a silo to back said conveyor screw, horizontal carrying arms connected to the conveyor screw to move in unison therewith about the main vertical axis and extending from the conveyor screw on opposite sides thereof substantially at right angles to the axis of the screw, supporting rollers which are carried by and pivotally connected to the carrying arms and individually adjustable in height relative to the carrying arms and are disposed on op- posite sides of the duct at different radial distances from the main vertical axis and rotatable on horizontal axes which are substantially at right angles to the axis of said conveyor screw, propelling roller means comprising at least one propel- ling roller which is rotatable on a horizontal axis to move the conveyor screw about said main vertical axis, the radial distances and the radial extents of the supporting rollers and the propel- ling roller means being such that the circular ring-shaped orbits described by the rollers and roller means during the rotation of the apparatus adjoin so that they cover substantially the entire surface of the silage in the silo, a throwing blade detachably connected to said conveyor screw for rotation there- with at said inner end thereof and associated with said lower end of said duct, propelling drive means for operating said propelling roller means to move the conveyor screw about said main vertical axis in a predetermined sense, and reversible drive means for rotating said conveyor screw about its axis selectively in one sense and the other.
