The illustrated embodiment is constructed as described above, and its operation will be explained below.

At the time when the sprouting length reaches approximately 11 J, after traveling the germination trolley B located outside the frame 23 shown in FIG. ) is engaged with a chain attachment (not shown) of the chain 9, and by driving the chain 9 in the direction of arrow C, the above-mentioned germination table j and Ili B are carried into a predetermined location within the front area X. .

After carrying the germination cart B to a predetermined location, the first motor 31 is slightly driven in the forward rotation direction, and the forks 19 and 19 located between the cart substrate 3 and the seedling box a are rotated to t? After raising the i-layer box A by a slight amount, the above-mentioned germination table 17B is carried out in the direction of arrow d and retreated outside the frame 23.

- On the other hand, greening vehicle C is driven by Subrocket l-@15.
is transported in the direction of arrow e in FIG.

Next, the aforementioned first motor 31 is driven to raise one fork via the chain 28.

V1 on this fork 19 due to the upper limit of this one fork
The FVr box A is lifted up in the front area X in the direction of arrow f in FIG.

By this lift-up, when the limit switch 57 shown in FIG.
f: Power to the fork 31 is cut off overnight, and the lifting of one fork and the stacked box A is stopped.

Next, when the piston rod 54 of the J cylinder 53 shown in FIG. 5 is moved forward and forward, the pair of hooks 48, 48 swing from the state shown in FIG. 6 to the state shown in FIG. 7 via the gear device 55. Therefore, the top layer seedling growing box a can be held between these pair of hooks 48 and 48.

Next, a little amount of the above-mentioned 1st July 31.
Then, lower the chain 28 and one fork to separate the uppermost seedling growing box a from the stacked boxes A below it.

Next, with the uppermost seedling growing box a being held between the pair of hooks 48, 48, the second motor 43 is driven in normal rotation, and the titting unit 40 is moved through the chain 39, 39. is conveyed in the direction of the arrow Q in FIGS. 1 and 5, and when the jacking unit 40 reaches a predetermined position in the rear area Y, the drive of the second motor 43 is stopped.

Next, the gear device 70 is driven by driving the third motor 66 described above.
The lifting unit 73 is raised in the direction of the arrow in FIGS. 1 and 8 via a chain 74 74 stretched in the vertical direction, and stopped at a predetermined height (O position) for transferring the seedling box.

When the piston rod 54 of the cylinder 53 shown in FIG. 5 is contracted and moved back while the lifting unit 73 is stopped at the predetermined height position for transferring the seedling box described above, the rod 54 moves [ hook 4 via gear device 55
8.48, this luff 48.48 returns from the state shown in FIG. 7 to the state shown in FIG.
．． 48 is opened, the top layer seedling growing box a, which was held by the left and right pair of hooks 48 and 48, is placed on each of the two chains si, si in the lifting unit 73 at the above-mentioned predetermined height position. It will be transferred to.

In this way, the top layer of the front area
... ri! After being transferred onto the above-mentioned chain 81° 81 in area Y, the third motor 66 is driven to move the above-mentioned lifting unit 73 through the gear device 70 and the chain 74, 74 as shown in FIGS. 1 and 8. descend in the direction of the arrow.

The above-mentioned descent of 73 to this elevating unit 1 is carried out through the above-mentioned through hole (
By controlling the above-mentioned 3U-Y 66 in response to a signal from a charging switch (not shown) that moves up and down together with the elevating unit 73 along the It is controlled to descend and stop to a position opposite to "Box Storage" 1.

When the chain 81.81 of the unit 73 is run in the direction of the arrow in FIG. 1 and FIG. The seedling raising boxes a... transferred thereto are pressed by the insertion plate 2 and inserted onto a predetermined seedling raising box storage shelf 1 in the greening cart C while being guided by the guide plates 82 and 82 on the left and right sides.

When inserting the seedling box a... using the insertion plate 2, a flexible nJ guide 84.84 is provided at the insertion end of the elevating unit 73.
The above-mentioned seedling box a moves toward the greening cart C while pushing it open against the spring force, so even if a small seedling box with left and right dimensions is inserted, this small seedling box can be securely moved to the greening cart C. Seedling raising box storage (can be transferred to FF11).

Hereafter, by repeating such an action, the front area
Seedling boxes a on the side...The seedling boxes a on the lifting unit 73 are sequentially held and transferred to the rear area Y starting from the topmost one. Transferred to Naesu Storage Town 1.

In the above process, raise and lower the seedling box a on the germination trolley B using the front lid D, raise and lower the raised seedling box a, and use the crane E to hold only the top layer of the seedling box a. After transporting it to the rear area Y, in the rear area Y, transfer the above-mentioned seedling raising box a to the lifting device ``which goes up and down below the crane E, and then transfer the lifting device F to the seedling raising box storage a1 of the greening cart C,
At this predetermined height position, the seedling box a on the lifting device F is moved to a predetermined seedling box storage shelf of the greening cart C using the above-mentioned insertion plate 2. 1, so the seedling raising box a loaded on the germination trolley B
There is an effect that the greenery can be automatically transferred to the greening trolley C one after another without requiring any manual labor.

In terms of the correspondence between the configuration of this invention and the above-described embodiments, the lifting means of this invention corresponds to the embodiment of the lift D, the crane means corresponds to the crane E, and the elevating means corresponds to the lifting device F. Although the insertion means corresponds to the insertion plate 2, the present invention is not limited to the configuration of the above-described embodiment.

For example, it is of course possible to use a germination cart B without the holding member 6 and the beam 7, and to move the stacked box A up and down together with the cart B using the aforementioned fork 19.

In addition, in the above-mentioned embodiment, the uppermost layer seedling growing box a...
The structure was designed to hold and transport a total of four boxes at the same time.
Needless to say, it is also possible to configure so that 2 boxes, 6 boxes, 8 boxes of seedling growing boxes a, etc. are held and transported at the same time.
