摘要

PROBLEM TO BE SOLVED: To excellently unload long straws regardless of occurrence of longitudinal straws in which waste straws are conveyed in a position along a nipping and conveying chain. SOLUTION: The waste straw unloading structure for a combine harvester is equipped with a change member 33 for changing waste straws conveyed by the nipping and conveying chain 16 from a shredding and unloading state for supplying waste straws to a shredding apparatus 8 and unloading to a long straw unloading state for passing waste straws above the shredding apparatus 8 and unloading the waste straws in long straws as they are. The change member 33 is equipped with a separation arm 37 that is positioned at the side of the nipping and conveying chain 16 and separates waste straws conveyed from the nipping and conveying chain 16 and a guide plate 38 for guiding waste straws from the separation arm 37 to a long straw unloading position in the long straw unloading state. The waste straw unloading structure is equipped with a receiving tool 40 for receiving waste straws that are conveyed in a position along the nipping and conveying chain 16 by the nipping and conveying chain 16 and flow from a gap 39 between the conveying end of the nipping and conveying chain 16 and the guide plate 38 into the shredding apparatus 8 side in a standing position in a long straw unloading operation.
