DEVICE FOR CIRCULARLY SHIFTING CULTIVATION SHELF

摘要

PROBLEM TO BE SOLVED: To provide a device for circularly shifting cultivation shelves with which cultivation shelves adjacent to one another do not interfere when circularly shifting the cultivation shelves in spite of disposing a plurality of the cultivation shelves as closely as possible. SOLUTION: The device for circularly shifting cultivation shelves includes: a plurality of endless conveyers 3A-3C to which a plurality of cultivation shelves 2 are connected and the circulation path for which is formed into a circular state; and a driving mechanism 4 which drives the endless conveyors 3A-3C to circularly shift the cultivation shelves 2. The cultivation shelves 2 adjacent to one another are connected to the endless conveyors 3A-3C, and the driving mechanism 4 drives a plurality of the endless conveyors 3A-3C independently to relatively broaden or narrow the intervals between the cultivation shelves 2 adjacent to each other.
