PROBLEM TO BE SOLVED: To return lifted/discharged grain from a grain lift device to the grain lift device by changing a passage of the grain discharged from a grain lift device from a main outgoing passage to a sub outgoing passage during an interval of intermittent processing operation of a subsequent processing device.SOLUTION: When grain in a flexible container bag H reaches a preset weight, a changeover shutter 60 automatically closes a main outgoing passage A of a discharge pipe 26 by a solenoid 37, and concurrently opens a sub outgoing passage B of a branch pipe 27. Thereby, the grain lifted to the discharge pipe 26 is returned from the branch pipe 27 to a storage hopper 24 so as to prevent the grain inside the discharge pipe 26 from getting full and from counterflowing to a grain-lifting cylindrical body 23. |
