Claim:
An apparatus for unloading seed or grain from a grain bin having a foundation, a sidewall extending upwardly from the foundation, and a grain-supporting floor defining the bottom of a grain storage space, comprising: a. frame comprising a first and second stage; b. the first stage comprising an inlet section adapted for insertion generally horizontally and into a grain bin and an intermediate section connected to the inlet section; c. the second stage comprising an outlet section adapted for extension outside a grain bin from the intermediate section; d. at least the inlet section having a relatively low profile to allow it to be generally horizontally positionable below a grain supporting floor of a grain bin; e. a conveyor operatively positioned on the frame generally including and between the inlet and outlet sections adapted to receive grain through a grain supporting floor by gravity at the inlet section and, when operated, move grain to and drop it by gravity from the outlet section; and f. the conveyor comprising an endless conveyor belt having a conveying side and a return side; g. the conveyor along the inlet section and intermediate section being generally along a first plane and along the outlet section along generally a second plane that is at an obtuse angle to the first plane; h. the conveying side of the conveyor belt along the intermediate section extending a distance over the conveying side of the conveyor belt along the outlet section of the conveyor.
