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. Also, since the placement and movement frame 7 is configured to move intermittently by one box, placement from the placement and movement frame 7 to the placement place 1 and seedling raising to the placement and movement frame 7 are performed. When the supply of the box A is simultaneously advanced, it can be performed smoothly and reliably. That is, when the nursery box A is supplied from the nursery box supply unit 22 to the placing and moving frame 7, since the placing and moving frame 7 is stopped, the nursery box A is prevented from being shifted with respect to the placing and moving frame 7. And it can be placed on the floor smoothly. Thus, the seedling box supply unit 22 is provided movably in the left-right direction with respect to the traveling frame body 4 and moves left and right by an interval L that is a difference from the width of the seedling box A that is larger than the width of the rail 2. Since the movement stopping member 53 is provided as described above, when the nursery box supply unit 22 is moved left and right, each of the left and right stoppers 43 provided in the nursery box supply unit 22 is located substantially above the left and right rails 2. That is, the innermost seedling raising box A on the placement moving frame 7 can be placed near the rail 2.

Therefore, the seedling box supply section 22 can supply the seedling boxes A one by one, and if the seedling box A has stoppers 43 on both left and right sides to stop the seedling boxes A on the return path, as described above, When the nursery box supply unit 22 is moved left and right,
The innermost seedling raising box A on the placement moving frame 7 can be placed near the rail 2. Thus, the seedling box supply section 22 forms a window hole 48 in a bottom plate 46 provided below the mounting shaft 30, and the window hole 48 is located on the vehicle body lateral frame 5 of the traveling frame body 4. Since the guide running roller 49 is fitted to the upper side of the vehicle body lateral frame 5 and the seedling box supply unit 22 is placed thereon,
Can move in the left-right direction with respect to the traveling frame 4. In the embodiment, the moving position of the nursery box supply unit 22 is switched left and right by a manual operation, but a motor may be used. Thus, a pair of front and rear vertical plate-shaped shock absorbing rotating members 54 are rotatably provided on the left and right sides of the placement moving frame 7 by a shaft 58, and the shock absorbing rotating members 54 The seedling raising box A is supported on the forward path for transferring the seedlings, and it is configured to rotate downward on the return path where the seedling raising box A is lowered. Therefore, the return path moving toward the center side does not interfere with the floor surface or the like. When it hits a convex part, it can rotate upward and escape, and it is located upward on the outward path where there is a risk of interfering with the floor surface without rotating upward. 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 even if the unlocking body 66 comes into contact with the guide portion 65 on the outward path for transporting the seedling raising box A, the hook portion is engaged. Since the engagement shaft 61 is engaged with the lock 64, the lock release member 66 does not rotate, and the lock release member 66 is elastically deformed and retracts. Conversely, on the return path, the guide portion 65 rotates against the lock release member 66. The seedling raising box A is rotated downward by its own weight, and the rotating plate 55 is provided with a contact member return contact provided in the moving path from the forward path to the return path below the seedling box supply section 22. It comes into contact with the contact body 67 and returns to the supporting state. Further, the front and rear widths of the placing and moving frame 7 can be arbitrarily configured. In particular, since the seedling raising boxes A are configured to be arranged side by side, the growing of the left and right side seedling raising boxes A in the seedling raising in the house. Even if there is a delay, it is only necessary to remove the part and supply it to the rice transplanter, so that no waste of seedlings occurs. 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. Therefore, usually, the innermost seedling raising box A is stopped by the stopper 43 and only the placement moving frame 7 is moved.
The seedling boxes A to be placed are arranged side by side without gaps (FIGS. 1, FIG. 2, FIG. 11, FIG. 21 and FIG. 22 show gaps between the adjacent seedling boxes A for convenience of understanding. is there),
The seedling box A1 is provided on the traveling frame 4 based on the left and right vehicle body side frames 6.
The mounting rod 103 in the front-rear direction is provided at an interval larger than the interval of the individual pieces. When the placement and movement frame 7 is in the forward movement, the tip of the seedling raising box A rotates upward when the leading end of the seedling raising box A comes into contact with the spacing regulation stopper 104, and the placement is stopped. When the moving frame 7 moves backward, the placing and moving frame 7 passes, but when the end face of the seedling raising box A comes into contact with the distance regulating stopper 104, the distance regulating stopper 104 comes into contact with the side surface of the mounting rod 103 and does not rotate. Therefore, at this position, the seedling raising box A is immobilized and placed on the field.

Therefore, since each seedling box A is brought down to the field in contact with each interval regulating stopper 104, a gap can be provided between the seedling boxes A and they can be juxtaposed. Improve the cultivation environment such as sunshine. Also,
When selecting and lowering each of the interval regulating stoppers 104,
The whole seedling raising box A moves forward under the space regulating stopper 104, and only the desired seedling raising box A comes into contact with the space regulating stopper 104 on the return path, so that it can be placed at a desired interval. However, in the embodiment, since the seedling raising boxes A are placed in the order of right and left in the figure, the box detecting device 70 is provided on the vehicle body side frame 6 of the left traveling frame 4, and the box detecting device 70 The lower horizontal plate 73 is formed shorter than the horizontal plate 71 to form the contact portion 7.
The detecting member 76 is so arranged that the rotating member 5 always rotates toward the rail 2 by its own weight.
, The upper horizontal plate 71 is normally separated from the detection unit 80, and the seedling raising box A is rotated upward by being pushed by the inclined plate 74, and the tip of the seedling raising box A slides on the inclined plate 74. While contacting the detection member 76 with the outer surface (side surface) of the seedling raising box A.
5 makes contact, whereby the detecting section 80 detects the upper horizontal plate 71 approaching the window hole 79, and then the traveling frame 4 is advanced by an advance operation by another switch. When the end face of the box A is slid and the contact portion 75 passes through the end face of the seedling raising box A, the detection body 76 is rotated downward by its own weight around the shaft 78 to be in a standby state, and the upper horizontal plate 71 is in the detection section. 80, the traveling of the traveling frame 4 is automatically stopped. In this case, since the detection body 76 is provided inside the traveling frame body 4,
It does not come in contact with the seedling box A that has already been laid, but
Stop where it can be laid.

Since a net roller or a sheet roller 81 for root cutting is provided on the front side of the vehicle body lateral frame 5 of the traveling frame 4 located on both the left and right sides of the rail 2, the net or the sheet is provided. When the traveling frame 4 is moved forward by fixing the end of the moving frame 4 to the loading place 1, the traveling frame 4 places the seedling raising box A on a net or a sheet. In this case, the seedling raising box A of the embodiment is formed of a synthetic resin and has a large number of pots vertically and horizontally, and cannot be grown sufficiently with the soil in the pot. I have. Therefore, it is necessary to place the seedling raising box A on the loading place 1 and then sufficiently squeeze it to bring each pot into close contact with the soil, but this operation is considerably troublesome. A pair of mounting arms 86 are provided on the left and right sides of the traveling frame body 4 on the rear side of the vehicle body horizontal frame 5 with the rail 2 interposed therebetween, and a screw shaft 87 is screwed to a rear portion of the mounting arm 86. The upper end of a spring (traction spring) 88 is locked to the lower end of the shaft 87, and the tread plate 89 is attached to the lower end of the spring 88. Therefore, when the single row seedling raising box A is placed and the traveling frame 4 is moved forward. Since the step board 89 is superimposed on the seedling box A on which the step board 89 is placed, the seedling box A together with the step board 89 can be pressed down, and the operation is easy. That is, the running frame 4 is advanced by one row for the seedling raising box A, and the stepping work is performed by the tread plate 89 during the laying operation of the seedling raising box A. Therefore, work efficiency is also improved.

Next, the laying operation is completed in one line (the stepping operation is performed during the laying operation), and the traveling frame 4 is moved forward.
When descending from the step board 89, the spring 88 pulls the step board 89 to retreat above the upper surface of the seedling raising box A. Therefore, simply stepping down from the step board 89 can move the step board 89 to the moving position, thereby facilitating the operation. In this case, since the step board 89 is attached to the spring 88 at the position of the center of gravity at which the front end moves slightly upward, the step board 89 prevents the step board 89 from being caught on the upper surface of the seedling raising box A during forward movement. In the second embodiment shown in FIG. 20, the base of a turning arm 90 is pivotally attached to the rear side of the vehicle body lateral frame 5 of the traveling frame 4 so that the rear end of the turning arm 90 is bent. A tread plate 89 is attached to the lower end so as to be pivotable back and forth.
Is provided below, and the spring (compression spring) 88 is inserted through the outer periphery of the screw shaft 87 between the lower surface of the rotating arm 90 and the upper surface of the spring receiver 91. When the user rides on 89, the turning arm 90 turns and comes into close contact with the upper surface of the seedling raising box A.
0 rotates and retreats from the upper surface of the seedling raising box A.

In this case, since the space between the step board 89 and the lower end of the rotating arm 90 is attached via the link rod 93,
The step board 89 is completely in close contact with the upper surface of the nursery box A. Since the seedling raising box A of the embodiment grows seedlings using the soil of the mounting place 1 as floor soil, the seedling raising place 1 cannot walk on the mounting place 1, and is transferred from the rear side of the seedling raising box parallel device 3 to the transport cart 110. The seedling raising seedling box A is transported and the seeding seedling raising box A is supplied to the supply cart 12.
0, and the seedling box A, which has been replaced on the supply cart 120, is supplied to the seedling box supply unit 22 of the seedling box parallel unit 3. Therefore, the seedling box to the seedling box supply unit 22 of the seedling box parallel unit 3. The supply of A can be made continuous and the operation can be made very efficient. . In this case, the reloading work is performed on the side of the transport trolley 110 and the supply trolley 120.
Since the tread plate 124 is provided on the side of 20, it can be easily performed.

Since the tread plate 124 is suspended by the spring 126 on the side of the supply cart 120, the tread plate 124 is lowered when the tread plate 124 is stepped on, and the reloading operation is performed in this state. Next, when the reloading operation (supply operation) is completed and the supply cart 120 is advanced from the tread plate 124 to advance, the spring 12
Numeral 6 pulls the treadle 124 to retreat above the upper surface of the seedling raising box A. Therefore, simply stepping down from the tread plate 124 can move the tread plate 124 to the moving position, facilitating the work.
In this case, the step board 124 is at the front end (on the side of the nursery box paralleling device 3).
Since the front spring 126 is strengthened so as to move up slightly, the tread plate 124 prevents the upper surface of the seedling raising box A from being caught in the forward movement.

The mounting arm 125 is attached to the traveling frame 121.
When the mounting arm 125 is attached to the traveling frame 121 on the opposite side, the tread plate 124 can be provided on the opposite side. Therefore, it can be provided on the side where the worker can easily work, and the workability is improved. Since the tread plate 124 is suspended by the spring 126, the spring 126 is twisted and mounted on the opposite side only by changing the direction of the mounting arm 125 by 180 degrees. Of course, it may be provided on both left and right sides of the supply truck 120 from the beginning.
