Abstract:
1. An unloader system for bulk materials, comprising: an elongate conveyor including a first end supported on a support structure for pivotal movement about a pivotal axis from a stored position, to an operating position, the conveyor extending longitudinally from the first end to a free end spaced from the support structure; an elbow that is positioned on the elongate conveyor between the first end and the free end, the elbow permits extension of the elongate conveyor all-through an upward motion thereof from the stored position to the operating position, the elbow further enables storage of the elongate conveyor along a longitudinal side of a vehicle associated with the elongate conveyor; and a raise system that generates the upward motion via a cam element and without hydraulic pressure, to mitigate placing a load on fluid systems of an agricultural equipment that hosts the unloader system; wherein the raise system includes a support element that comprises a cable; wherein the support element is configured to cause the elbow to straighten from a bent configuration to raise the free end of the elongate conveyor when pivoted to the operating position, and to cause the elbow to bend to lower the free end of the conveyor when pivoted to the stored position; wherein the support structure comprises a cart; wherein the cam element comprises a curved surface configured and positioned such that the flexible first end of the support element will conformingly engage therewith as the conveyor is pivoted toward the operating position.
