To provide a grain agitating device which is capable of well agitating grains for a long period by a rational improvement in its structure.
In the upper part of a storage space where the grains are stored, at least one supporting means existing on the upper side among the plural supporting means which are dispersedly arranged along the circumferential direction of the outer peripheral part of a shaft body 30 of a circular shape in its sectional shape directed in its longitudinal direction toward a horizontal posture and support a supporting frame 48 for supporting an agitating screw to agitate the grains toward the outer peripheral part of the shaft body 30 in a pendent posture are constituted to have roller bearings 60 which are supported on the supporting frame 48 side freely rotataby around the axial center intersecting with the longitudinal direction of the shaft body 30 and act to come into contact with the outer peripheral part of the shaft body 30. The device is provided with moving means which are disposed at the supporting frame 48 in the state of acting to come into contact with the outer peripheral part of the shaft body 30 freely movably along the longitudinal direction and also freely movably along the circumferential direction and drives the supporting frame 48 along the longitudinal direction of the shaft body 30.
