PROBLEM TO BE SOLVED: To smoothly unload grain stored in a grain tank to the outside of a machine by a grain unloading apparatus while simplifying the constitution of the grain unloading apparatus.SOLUTION: The grain unloading structure of combine harvester is equipped with the grain unloading apparatus 12 for unloading grain stored in the grain tank 11 to the outside of the machine; and the grain unloading apparatus 12 is equipped with a lift conveyor 16 for lifting grain in the grain tank 11 and unloading the grain from an upper outlet 16A, and an unloading chute 17 for dropping and guiding the grain unloaded from the outlet 16A to the outside of the machine. The unloading chute 17 is vertically swingably disposed on the lift conveyor 16 at the outlet side of the lift conveyor 16 so that a spindle 40 in a posture crossing the grain guide direction of the unloading chute 17 is used as a fulcrum and the base part of the unloading chute 17 is supported by the spindle 40, and the unloading chute is switched from a storage position along the lift conveyor 16 to an unloading position in which the free end side of the unloading chute 17 is separated from the lift conveyor 16. |
