PURPOSE: A multi-purpose grain stock/delivery apparatus is provided to achieve a superior conveying ability and grain selection efficiency, while reducing maintenance cost and noise. CONSTITUTION: A suction hopper(2) sucks grain from an external source by the suction force of a blower(1) generated by the vacuumization of the suction hopper(2) which is caused by mixing air into a blower inlet port(8) connected to an exhaust pipe(7) of the suction hopper. Thus-sucked grain is conveyed downward to a damper(3) arranged beneath the suction hopper, and compulsorily dropped to a discharge portion(12) by the rotation of a rotary feeder(16). Subsequently, the grain is discharged by the blowing force from the blower and conveyed upward to a hopper(30). An air control valve(6) for controlling the amount of air being sucked through a suction port(8) of the blower, is arranged at an outer end of the exhaust pipe. A rotation blade(17) having a rubber plate(17a) attached to an end of the rotation blade, is installed inclined at a rotation shaft(14) of the rotary feeder, in such a manner that the rotation blade is driven by a motor(15). The hopper(30) is formed into a cylindrical shape, and includes a grain discharge pipe(35) having a door(37) with a balancing weight(36).
