摘要：
A combine has a grain bin with a sump and an unloading system for unloading grain out of the bin. The unloading system has a pivoting unloading tube assembly movable between a storage position and an unloading position. The unloading tube assembly has an inner riser section and a variable-length outer transport section. When the unloading tube assembly is in the storage position, at least a portion of the inner riser section nests underneath a rear floor portion of the grain bin. The variable-length transport section has a proximal chute nested with a distal chute that can be moved relative the proximal chute. A nested conveyor assembly transports grain through the variable-length section. The nested conveyor assembly includes an endless conveyor and pulleys configured to form an upper grain transporting reach inside of the chutes and a return reach outside of the chutes.
