To provide a grain stirring device suppressing an agitating member from inclining.
In a stirrer 56, a guide shaft 64 is rotated and revolved around one end side, and chaff inside the grain tank is agitated by revolving, together with the guide shaft 64, a down auger 94 rotatably supported by the guide shaft 64. Since the guide shaft 64 is revolved by rotation on the rail of a reverse wheel engaged with the guide shaft 64 and rotated in an opposite direction of rotation of the guide shaft 64, the down auger 94 is applied with rotation force Q in the revolving direction of the guide shaft by rotation of the guide shaft 64. Accordingly, in the down auger 94, inclination force P in the opposite direction of revolving direction of the guide shaft 64 by resistance of the chaff M can be canceled by the rotation force Q in the revolving direction of the guide shaft 64 by rotation of the guide shaft 64, and inclination of the down auger 94 is prevented.
