Combine grain tank unloading mechanism.

摘要

A combine harvester comprises - a grain tank (5); and - a grain tank unloading tube (12) having an elongated main body portion (13) with conveyor means (15) therein and which is adjustably supported at one of its ends on the combine harvester base unit (1) for movement between a transport position generally in the longitudinal direction of the combine harvester and at least one operative unloading position extending generally laterally outwardly of the combine harvester and at an upward inclination relative to the horizontal, and is characterized in that the grain tank unloading tube (12) further also comprises an extension portion (20) with further conveyor means (41) therein and which is coupled to the distal end of the elongated main body portion (13); the extension portion (20) being positionable in at least a first and a further position at different angles relative to the unloading tube main body portion (13).
