By the rotation of , two pieces at a time are sent in the direction of the loading device (X direction).

In the first step, the solenoid 58 is energized and the stopper device 55 (B) is raised, so the seedling box passes under the stopper device 2155 (B) and is transferred to the stop position A, and the stopper device 55 It comes into contact with the receiving member 56 (A) and stops. At the same time, this detection switch 57 (
A), the loading air cylinder 70 (A) contracts, and the pressure plate 69 moves the two seedling boxes juxtaposed on the conveyor to the bottom of the front storage section S (A) of the greening cart 8. When the seedling box is stored in the storage area, the irrigation system W
19 solenoid valves 72 listen for a certain period of time, each water spray nozzle 74.
The seedling box is watered from... Next, motor 1
4' starts and the greening trolley 8 is installed at the interval h.
・Lower by minute. The above-mentioned watering and lowering may be performed at the same time.The pushing of the seedling box, watering, and lowering of the trolley are repeated in the same manner.
In (A), seedling boxes are loaded one after another from the bottom, and shrubs are placed in each seedling box.

When the seedling boxes are stored on all the shelves of the storage i'ifl S (A), the greening cart 8 is raised to the original upper limit position, and the solenoid 57 of the stopper device 55 (B) is de-energized. Therefore, the stopper device 55 (B) is lowered, and the seedling boxes that are subsequently transported are stopped at the transport stop position B. And this time, the loading air cylinder 70
(B) is operated and the seedling boxes are sequentially loaded into the storage section S (a) on the rear side of the greening cart 8.

When all the shelves of the greening trolley 8 are loaded with seedling boxes,
The moving air cylinder 62 extends and the greening trolley mounting base 61
is pulled out from below the greening trolley 8, so the fully loaded greening trolley is replaced with an empty greening trolley. After the replacement is completed, the loading device 4 is returned to its original position.

Next, the germination trolley 7 is moved forward, and the rear side a overlap position I is reached.
Transfer the seedling boxes I and II to the greening cart 8. In other words, the seedling boxes for one germination trolley are transferred to two greening trolleys. Since the greening cart 8 can accommodate the seedling box 99 with sufficient space above and below, light and space for leaf extension are ensured, providing favorable conditions for greening.

In the loading system fit of this embodiment, since the irrigation system 9 is installed on the upper part of the greening cart 8 which is the final process, the structural members of the system may get wet due to water splashing during the process in the middle of the process. In addition, if the soil in the seedling box contains a lot of water, it is easy to cause unevenness due to shocks caused by external forces, but this example prevents this. ing.

Note that the installation location of the irrigation device is not limited to the top of the greening trolley, and may be installed in other locations as long as the above-mentioned issues are satisfied.

[Effects of the Invention] As is clear from the above explanation, the nine seedling box transshipment systems according to the present invention can irrigate the seedling boxes at the same time as the seedling boxes are transferred from the germination cart to the greening cart. Therefore, it is efficient, and since watering is performed before the seedling boxes are loaded onto the greening cart, the best watering conditions can be easily obtained and it is effective.
