Abstract: A movable grain storage unloading apparatus for removing corn and other farm product material from a silo and conveying the corn to an adjacent container. The apparatus includes an elongated horizontal frame section for insertion within a silo, a generally upwardly-inclined frame section attached to the horizontal frame section from which corn is discharged, a pair of laterally-extending guards attached to the upwardly-inclined frame section, and a flat, non-moving conveyor bed extending from a lower reach of the horizontal frame section to an upper reach of the upwardly-inclined frame section and adapted for the conveyance of corn thereon. The apparatus includes a pair of endless linked chains adjacent the conveyor bed with vertically-extended crosspieces secured therebetween, the linked chains adapted for slidable movement on the conveyor bed and the crosspieces adapted for facilitating corn removal by directing the corn therealong.
