ABSTRACT:
An extension or companion conveyor is used with a primary conveyor to convey grain or other granular materials. The companion conveyor swings into a lesser angle than the primary conveyor, which may be at a relatively steep angle to convey grain into a tall bin. The companion elevator travels at a high rate relative to the primary conveyor to provide an accelerator function. A mounting mechanism between the companion and primary conveyors includes a swing arm pivotally connected in its opposite ends so as to swing the companion conveyor from end to end abutment with the primary conveyor forwardly and outwardly to a stored/transport position parallel to the primary conveyor. A slip connection in the mounting mechanism allows the angle of the companion conveyor relative to the primary conveyor to vary as it is folded against the primary to reduce the pushing force necessary to be applied by an operator during the first half of travel of the swing arm. During initial swinging of the arm, the slip connection causes the primary to be at a higher angle relative to the primary conveyor and thereby require a higher degree of force necessary to swing the companion conveyor through its first half of travel. However, to alleviate the otherwise relatively high degree of pushing force necessary to swing the swing arm beyond the halfway point, the slip connector shifts angular relationship at approximately the half way point to lessen the force necessary.
