PURPOSE:To equalize supply of grain irrespective of the height of the deposited grain, by providing a detector for detecting the height of the grain deposited in a tank, and increasing the rotational frequency of a rotating scattering blades in conformity with the height of the deposited grain. CONSTITUTION:When the height of the deposited grain in the storing tank 7 is below the prescribed height of the detector 10, and the detector 10 cannot detect the grain, the rotation of a varying speed motor 11 is controlled by a controller, and the grain is allowed by the rotating scattering blades 6 to fall along parabolas and to reach the side wall 8 below the detector 10 so that the height of the grain is leveled. When the height of the deposited grain reaches or exceeds the position of the detector 10, the height is detected by the detector 10 so that the rotational frequency of the varying speed motor 11 is increased by the controller 12. The grain is scattered by the rotational force of the rotating scattering blades 6, and is struck against the side wall above the position of the detector 10 so that the height of the grain can be leveled. |
