When the two seedling-growing trays 7 are supplied to the carry-in conveyor 9 so as to be arranged in the width direction of the carry-in conveyor 9, the carry-in conveyor 9 is driven and the seedling-growing tray 7 is conveyed to the right of the carry-in conveyor 9. And
When the nursery tray 7 reaches above the elevating frame 11, the carry-in conveyor 9 stops. After that, the elevating frame 11 rises to lift the seedling raising tray 7 to form a fork insertion space between the conveying surface of the carry-in conveyor 9 and the lifted lower surface of the seedling raising tray 7. Meanwhile, the traveling vehicle 20 travels to a position where the lateral center of the slide fork 24 is aligned with the middle of the left and right elevating frames 11, and then stops. At the same time, the lift 23 is lowered to the lowest position. Then, in this state, the slide fork 24 can be fitted into the fork insertion space between the transport surface of the carry-in conveyor 9 and the lower surface of the raised seedling-raising tray 7. After that, the slide fork 24 fits into the fork insertion space and is located right below the seedling raising tray 7. Then lift 2

After that, the slide fork 24 retracts to the side of the lift 23, so that the seedling-growing tray 7 is drawn into the traveling carriage 20. After taking out the seedling-growing tray 7 from the carry-in conveyor 9 in this way, the traveling carriage 20 stores the seedling-raising tray 7 in the left-right direction center of the empty seedling-raising tray placing shelf 3 and the left-right direction center of the seedling-raising tray 7 (slide fork 24). (Center in the left-right direction) and run to stop. Elevator 23
Is in the uppermost position, but in that state the slide fork 24
The lower surface of the upper seedling raising tray 7 is located above the upper surface of the seedling raising tray mounting shelf 3. After that, the seedling raising tray 7 on the slide fork 24 is moved to the back of the seedling raising tray mounting shelf 3 and the carriage passage 1 by the operation of the slide fork 24 which is the reverse of the above.
If all of the eight sides are vacant, they are lowered to the back, and if only the trolley passage 18 side is vacant, they are lowered to the trolley passage 18 side. It should be noted that it is detected by the ultrasonic sensor 25. The seedling-raising tray 7 on the seedling-raising tray placing shelf 3 on which the seedlings have been raised can be carried out to the carry-out conveyor 13 by an operation substantially reverse to the above.

While the traveling carriage 20 is moving in the transfer operation of the seedling raising tray 7, or while the operation of the traveling carriage 20 is stopped, the traveling carriage 20 is caused to travel and water is sprayed from the sprinkling nozzle 27 to mount the seedling raising tray.
