PROBLEM TO BE SOLVED: To provide a structure which hardly allows a grain level sensor of a grain tank to be affected by grains flowing in from an inflow port.SOLUTION: The combine includes: a cylindrical formation body 53 arranged in a grain tank 16 and forming a grain passage 53P including an inlet 72 taking a part of conveyed grains thereinto and an outlet 73 discharging the grains; a temporary storage part 530 located in the grain passage 53P; a storage shutter 76 capable of changing a position between a closed position in a horizontal posture storing the grains in the temporary storage part 530 and an opened position in a downward posture discharging the grains; a grain level detector 41 arranged in the grain passage 53P and detecting a distance having reached a predetermined value, the distance being between a lower edge of the storage shutter 76 in the downward posture and an upper face of the grains; and a shutter control part 92 stopping the storage shutter 76 based on a detection signal of the grain level detector 41.SELECTED DRAWING: Figure 1 |
