ABSTRACT:
An agricultural harvester has a grain bin with an oblique side wall section at one lateral side of the grain bin presenting a discharge opening, an unloading tube with an end portion pivotally mounted on the oblique side wall section for swinging movement about the axis of the discharge opening, and a linear hydraulic actuator and support structure therefor disposed in a pocket in the one lateral side of the grain bin. The cylinder and piston components of the actuator are pivotally connected, respectively, to the support structure and the unloading tube. A grain bin auger is disposed in the bottom of the grain bin, an unloading auger is disposed in the unloading tube and an inclined intermediate auger has its opposite ends connected to ends of the grain bin auger and the unloading tube auger by universal joints. An alignment adjustment joint is provided in the unloading tube to permit offsetting the effect of tolerance buildup occurring in manufacture of the unloading tube and its support structure.
