PURPOSE:To brush off the grain efficiently by projecting the rubber vane at the tip of a rotary vane and raking out the grain through the elasticity of the rubber vane. CONSTITUTION:A rubber vane 4 the tip of which is projected from the edge 3 of a rotary vane 1 is provided on the rear face 2 of the rotary vane 1 provided at the discharge port of the hopper. Since said rubber vane 4 will rotate while sliding with the receiving plate 10 thereby the grain is discharged entirely and the damage due to the holding of the grain can be prevented reliably. |
