Abstract
A grain bin adapted to be mounted on the upper part of an agricultural combine is provided with at least one "floating" bin side wall extension which is automatically movable into substantially vertical grain-retaining position as the bin approaches and reaches a full condition. Clean grain which has been separated from the straw, chaff or the like is conveyed by an elevating conveyor which discharges the grain via a chute into the intake end of an elongated "floating" bin loading conveyor which is pivotally mounted for angular movement in a vertical plane. In the illustrated embodiment, the bin loading conveyor is an auger conveyor and the rotatable shaft of the floating auger conveyor is driven by a suitable drive means through a universal joint. As the grain level in the grain bin approaches a full condition, the bin loading conveyor moves angularly upwardly from a horizontal position due to an upward thrust on the bin loading conveyor caused by the reaction of the grain discharging from the bin loading conveyor against the upper surface of the already loaded grain. In the illustrated embodiment, a pair of oppositely disposed bin side wall extensions are hingedly connected to th…
