PROBLEM TO BE SOLVED: To transport and unload grains in a grain storage tank to the outside of a machine by a grain transporting and unloading cylinder apparatus of simple constitution and to simply and completely house the apparatus. SOLUTION: The grain unloading apparatus for a combine harvester has constitution that, when the foldable upper part transport cylinder 10 of the grain transporting and unloading cylinder apparatus 8 having the upper part transport cylinder 10 is housed at a fixed position in the vertical direction for transporting and unloading grain stored in the threshed grain storage tank 6 to the outside of a machine, the upper part transport cylinder 10 is housed in a folded state in the left oblique direction of the machine body 1a forward. When the upper part transport cylinder is folded and housed, the transport end part of the upper part transport cylinder 10 is inclined downward from horizontality. Even if the threshing cylinder cover 5b of a thresher 5 is operated to open, the cover is not brought into contact with the upper transport cylinder 10 in a housed state. COPYRIGHT: (C)2006,JPO&NCIPI
