Abstract

A self-unloading container apparatus comprises a container mounted on a vehicle. An upright auger tube has its bottom end in the container and top end outside the container. An intermediate auger tube is pivotally attached at one end to the upright auger tube so as to pivot about a pivot axis on a pivot plane and at the other end to a lateral auger tube at a fixed oblique angle. A universal joint connects the intermediate flighting shaft to the upright flighting shaft with the center of the joint on the pivot plane and axis. A constant velocity universal joint connects the intermediate flighting shaft to the lateral flighting shaft with a center thereof located at the intersection of axes of the intermediate and lateral auger tubes. The lateral auger tube pivots from a transport position aligned with the travel direction, to an operating position transverse to the travel direction.
