  That is, the grain located at the lower end 12 a of the grain tank 12 is conveyed to the front side of the machine by the bottom screw 19 and discharged from the discharge port 20. As the grain discharge by the bottom screw 19 proceeds, the grain located on the left end side of the grain tank 12 flows to the lower end 12 a by natural flow and is discharged from the discharge port 20 by the bottom screw 19. The longitudinal conveying portion 41 is driven by the driving force of the bottom screw 19, and the horizontal conveying portion 45 is driven by the driving force of the vertical conveying portion 41, and the grain discharged from the grain tank 12 is conveyed by the vertical conveying portion 41.
