PURPOSE:To store a discharge conveyor at a low position in a stable state, by lowering an opening at the top of a grain raising column than the top position of a main tank and a subtank and making the discharge conveyor stable in a dent part between both the tanks. CONSTITUTION:An opening 6 to both a main tank 1 and a subtank 5 is set at the top of a grain raising column 3, a dent part A is laid between the main tank 1 and the subtank 6, a discharge conveyor 2 is made storable in the dent part and the discharge conveyor 2 is stored at a low position. The plane area of the tanks 1 and 5 can be enlarged as wide as possible and the discharge conveyor is neither vibrated nor oscillated in a stored state.
