Abstract:
1. An unloading auger elbow for use on an agricultural harvester, comprising: a unitary tubular cast body having a circular grain inlet centered on a generally vertical pivot axis and being configured to receive a flow of grain from a generally vertical auger tube of a generally vertical auger assembly, and a circular grain outlet configured to transmit the flow of grain to a generally horizontal auger tube of a generally horizontal auger assembly, wherein the unitary tubular cast body includes a pivot joint mounting member forming an upper exterior region of said elbow at a location along said pivot axis, with said mounting member including an upper machined mounting surface extending approximately perpendicular to, and surrounding said pivot axis; and a pivot joint centered along said pivot axis and being fastened to the pivot joint mounting member, wherein the pivot joint comprises a first pivot member and a second pivot member, and further wherein the first pivot member includes a bottom surface disposed in engagement with said upper machined mounting surface of the pivot joint mounting member, and the second pivot member is coupled to the first pivot member so as to permit the first pivot member to pivot with respect thereto about said pivot axis; and wherein the tubular cast body further comprises a second machined surface configured to support the unloading auger elbow assembly on the generally vertical auger tube of the generally horizontal auger assembly, and the second machined surface being annular and machined concentric with, and approximately perpendicular to, the pivot axis and adjacent said inlet, and wherein the tubular cast body further comprises an integral annular flange centered on said pivot axis and surrounding said inlet, and a pivot arm connector being formed integrally with said flange.
