In this case, since the transport vehicle 119 also has the turntable 107, the mounting rail 109 of the transport vehicle 119 and the mounting rail 109 of the carry-in vehicle 102 are provided.
It can be connected easily. And greenhouse 2
When the seedling box paralleling device 3 is carried into the rail 2a, the seeded seedling box A stacked vertically by any means is supplied to the seedling box supply unit 22 (FIG. 11A).
Is moved to the right by the interval L because the placement moving frame 7 moves to the right (FIG. 11B), and then the frame moving motor 20 is energized to provide space for one right end of the placement moving frame 7. Is moved to a position below the seedling box supply unit 22 and then stopped. Next, in this state, the supply motor 39 is energized,
The cam plate 36 is rotated via the transmission shaft 40, the bevel gear 41, the bevel gear 38, and the rotation shaft 35. The cam plate 36 moves the roller 34 up and down, whereby the rotating arm 33 rotates to rotate the mounting shaft 30 in the forward and reverse directions.
Member 31 supporting seedling box A by forward and reverse rotation of
Pivots from the support position S to the retreat position T, the entire seedling box A in the seedling box supply space 28 falls onto the placement and moving frame 7, and then moves from the retreat position T to the support position or to the support position S. When 31 returns, the lowermost seedling raising box A remains on the placement moving frame 7, and the support member 31 is engaged with the flange 32 of the second lower seedling raising box A and lifted to the supporting position S to support. I do. In this way,
One seedling raising box A is supplied to the placement moving frame 7.

Again, the frame moving motor 20 is rotated forward to move the placing and moving frame 7 by one box toward the right standby section 42 (FIG. 11C). Since the placement space is located below the seedling box supply unit 22, the frame moving motor 20 is stopped, and then the supply motor 39 is energized to move the seedling box A by the seedling box supply unit 22 located on the right side. Supply (FIG. 11C), and this is repeated (FIG. 11D,
E), the seedling raising box A is placed over the entire length of the placement moving frame 7 and is located in the right standby section 42 (FIG. 11F). Next, in this state, when the nursery box supply unit 22 is first moved to the left, the stopper 43 in the retracted state located on the upper surface of the innermost nursery box A passes the end face of the nursery box A. It turns to the upright position and is located substantially above the right rail 2a (FIG. 1).
1). Next, when the frame moving motor 20 is reversed to open a placement space for one seedling raising box A on the left end of the placement moving frame 7, this placement space is At the lower position, the frame moving motor 20 is stopped, and then the supply motor 39 is energized to supply only one seedling raising box A by the seedling raising box supply unit 22 (FIG. 11).
J).

At this time, since the left end face of the seedling raising box A on the right side of the stopper 43 is in contact with the stopper 43, when the placing and moving frame 7 moves to the left, only the placing and moving frame 7 moves. The inner seedling raising box A comes into contact with the stopper 43 provided on the other side plate 25 and becomes immobile, and the seedling raising box A adjacent to the seedling raising box A blocked by the stopper 43 comes into contact with the whole seedling raising box A. Is blocked and becomes immovable with respect to the placement moving frame 7, and moves until one placement space for one box is opened on the left side, and one nursery box A on the right side falls and is placed ( (Fig. 11h). Again, the mounting moving frame 7
Is moved to the left by one box, the right seedling raising box A falls (FIG. 11), and the space of the left placement moving frame 7 faces below the seedling raising box supply section 22. (Fig. 1
1 l), when this is repeated (nu, le, oh, wa in FIG. 11),
The seedling raising box A is placed in the loading place 1 on the right side of the rail 2 while the placement moving frame 7 is moved to the left to supply the seedling raising box A.
Next, although illustration is omitted, when the seedling box supply unit 22 is moved to the right and the placement moving frame 7 is moved to the right, 1
The next seedling box A is supplied onto the placement moving frame 7 moved to the right after the parallel operation of the seedling boxes in the row is completed. In this state, the traveling frame 4 is moved forward, and the above operation is repeated. ,
The seedling box A can be juxtaposed on the left and right sides of the central rail 2 by performing the parallel work of raising the seedling boxes in the second and subsequent rows.

Therefore, when the placing / moving frame 7 moves from the one waiting section 42 to the other waiting section 42, the seedling raising box A on the placing / moving frame 7 on the one waiting section 42 side is lowered and the other waiting section 42 is placed on the other side. Since the nursery box A is supplied on the placing and moving frame 7 on the side of the section 42, the work efficiency is improved, that is, the seedling box A is supplied on the placing and moving frame 7 only in the first row of the initial operation. Therefore, it is necessary to move the placing and moving frame 7, but at the time of the second row, the nursery box A has already been supplied on the placing and moving frame 7,
Improve work efficiency. Thus, the seedling box supply unit 22 is provided with the bottom plate 4 provided below the mounting shaft 30.
6, a window hole 48 is formed on the vehicle body lateral frame 5 of the traveling frame 4 and the guide traveling roller 49 is fitted in the window hole 48. When the seedling box supply unit 22 is placed on the upper surface of the seedling box supply unit 22, the seedling box supply unit 22 can move in the left-right direction with respect to the traveling frame 4. In the embodiment, the nursery box supply unit 22 is manually operated.
Are moved to the left and right, but a motor may be used.

On the left and right sides of the placing and moving frame 7,
A pair of front and rear vertical plate-shaped shock absorbing rotating members 54 are
Since the impact-releasing rotating member 54 is configured to support the seedling raising box A on the outward path for transferring the seedling raising box A and to rotate downward on the return path for lowering the seedling raising box A, On the return path moving toward the center side, it does not interfere with the floor surface, etc., and if it hits a convex part, it can rotate upward and escape, and it may interfere with the floor surface without rotating upward. It is located on the upper part of the outbound route. In particular, since the net for root cutting is laid in the field scene, the impact of the fall is alleviated to prevent the scattering of the soil and seeds in the seedling raising box A, and to prevent the net from being caught on the net. That is, since the engaging shaft 61 is engaged with the engaging hook 62, it is securely supported, and the unlocking member 66 is attached to the guide portion 65 on the outward path for transferring the seedling raising box A.
Does not rotate because the engaging shaft 61 is engaged with the hook portion 64, the unlocking member 66 is elastically deformed and retracts, and conversely, the guide portion 65 is moved to the unlocking member 66 on the return path.
The seedling raising box A is rotated downward by its own weight, and the rotating plate 55 is rotated by the weight of the seedling raising box A.
Abuts against the contacting body return contacting member 67 provided on the movement path from the outward path to the return path below the contacting member and returns to the supporting state.

The front and rear widths of the placing and moving frame 7 can be arbitrarily set. Particularly, since the seedling raising boxes A are arranged side by side, the seedling raising boxes A on the left and right sides are used for raising seedlings in a house. Even if the growth of the seedling is delayed, it is sufficient to remove the part and supply it to the rice transplanter, so that the seedlings are not wasted. That is, when the seedling raising boxes A are arranged vertically, the seedlings in the outer row of the seedling raising box fail to grow, and the seedling mat is supplied to the rice transplanter in the vertical direction. If it is supplied, the plant will be out of stock, so that defective seedlings cannot be removed and one box of seedlings will be wasted. In this regard, if the laying is performed in a side-by-side arrangement, it can be supplied to the rice transplanter even if only that portion is removed.
