The present invention relates to a circulation type plant cultivation apparatus, which comprises a first rail unit having multiple rail layers laminated to be separated at predetermined intervals wherein a layer is formed by a pair of rails arranged to face each other to be separated by the width of a tray; a second rail unit having multiple rail layers corresponding to the rail layers of the first rail unit, and arranged to be separated from the rail layers of the first rail unit at predetermined intervals; a transport unit connected to the first and second rail units to be horizontally movable so as to move trays mounted on odd number rail layers of the first and second rail units to one side, and trays mounted on even number rail layers of the first and second rail units to the other side; a first elevation unit arranged on one side of the first rail unit and lifting the trays transferred from the odd number rail layers of the first rail unit to the even number rail layers; a second elevating unit arranged on the other side of the second rail unit and lowering the trays transferred from the even number rail layers of the second rail unit to the odd number rail layers; and a first elevating unit interposed between the first and second rail units, lifting the trays transferred from the even number rail layers of the first rail unit to the odd number rail layers, and lowering the trays transferred from the odd number rail layers of the second rail unit to the even number rail layers. The circulation type plant cultivation apparatus is characterized in that trays are circulated by being lifted in a zig-zag path by the first rail unit, the first elevating unit and a third elevating unit, and being lowered in a zig-zag path by the second rail unit, the second elevating unit and the third elevating unit. |
