PURPOSE:To dispense with a pit and improve efficiency by providing a filling hopper housing a rake-out blade on the lower end of each of a plurality of bucket elevators and forming the hoppers in a alignment so as to be mutually continued by means of rotatable partition plates. CONSTITUTION:Grains charged into each filling hopper 3A-3D are delivered to each bucket elevator 2A-2D through a connecting chute 23 by means of a rake-out blade 15. The grains are further charged into the corresponding filling tanks 1A-1D form the bucket elevators 2A-2D and, then, gradually sent to a rough selector. The filling hoppers 3A-3D are formed in a body by means of side plates 27 and a back plate 28 while being partitioned by means of revolvable partition plates 30a-30c. Hence, the filling hoppers may be used continuedly as necessary to increase a capacity. By this structure, a pit can be dispensed with improving efficiency.
