PURPOSE:To provide an inexpensive grain supply device which is simple and small-sized and which can be rapidly started while it can supply a large volume of grain. CONSTITUTION:A grain supply device is composed of a rice charging air conveying passage 7 which communicates a suction port 1, successively with the bottom of a rice charge tank 2 and the top of a rice storage 3, which has a discharge passage 4 extending from the top of the storage 3, which induces an air stream flowing from the suction port 1 through the above-mentioned communication route with the use of an air pump 5 located in a part thereof so as to pneumatically convey rice from the rice charge tank 2 to the rice storage 3. Further, the suction port 11 is also communicated successively with the bottom of the rice storage 3 and the upper part of a rice consuming tank 12 for receiving rice and consuming the same and also using the air pump 5. A rice feed air conveying passage 14 has a discharge passage from the top of the consuming tank 12, and induces an air stream flowing from the suction port 11 through the above-mentioned communication so as to pneumatically convey rice from the storage 3 into the consuming tank 12, and shut-off valves 6, 21, 22 are adapted to shut-off the passages 14, 7 as necessary. |
