PROBLEM TO BE SOLVED: To provide a combine which can easily discharge grains to a grain bag, etc. in an air conveyance type grain discharge device.SOLUTION: A first conveyance cylinder (20) for grain conveyance is divided into an upper side conveyance cylinder (121) on an upper side and a lower side conveyance cylinder (120) on a lower side. An upper end of the lower side conveyance cylinder (120) and a lower end of the upper conveyance cylinder (121) can be connected and separated. The lower side conveyance cylinder (120) can be freely rotated around an axial center (Z) in a machine body front/rear direction. A grain ratio, which is a ratio of a grain amount fed into a blowing cylinder (61) by a grain feed device (180) with respect to an air flow rate fed into the blowing cylinder (61) by a blowing device (60) is increased in a separated state of the upper side conveyance cylinder (121) and lower side conveyance cylinder (120) compared with a connected state of the upper side conveyance cylinder (121) and lower side conveyance cylinder (120).SELECTED DRAWING: Figure 8 |
