[0015]

According to the present invention, a seedling box supply section 22 is provided at the center of the traveling frame 4 and a plurality of seedling raising boxes A are placed on the left and right traveling frames 4 of the seedling box supply section 22. A standby section 42 is provided for waiting the seedling box 7 on both sides of the seedling box supply section 22.
Is provided with a stopper 43 that does not allow passage, and the placing / moving frame 7 is configured to alternately reciprocate between the one standby unit 42 and the other standby unit 42.
The seedling box A is supplied to the placing and moving frame 7 which is moved one by one by the seedling box supply unit 22. When the seedling box A is put on the entire surface of the placing and moving frame 7, Of the seedling raising box A is stopped by the stopper 43, and the placing and moving frame 7 is moved toward the standby part 42 on the opposite side, the seedling raising boxes A at the ends are sequentially placed, and the seedling raising boxes A are arranged side by side on the rail 2 side by side. Lay Box A.

In this case, the relationship between the seedling box supply section 22 and the rail 2 is such that the seedling box supply section 22 forms a seedling box supply space 28 having an area for accommodating one seedling box A in plan view. Since the rail 2 is formed to be smaller than the horizontal width of the seedling box A by the distance L, first, as shown in FIG. As it moves, it is shifted to the right by an interval L (FIG. 14).
B) When the predetermined position is reached, the lower side surface of the other side plate 25 of the seedling box supply section 22 comes into contact with the movement stopping member 53, and the lateral movement stops. In this state, since the placing / moving frame 7 is located on the left side, the frame moving motor 20 is rotated forward to move the placing / moving frame 7 toward the right standby unit 42, and the placing / moving frame 7 is moved. When the placement space for the seedling box A1 on the right side of the box is located below the seedling box supply unit 22, the frame moving motor 20 is stopped, and then the supply motor 32 is energized to supply the seedling box supply unit. Only one seedling box A is supplied by means of 22 (FIG. 14).
B).

Again, when the frame moving motor 20 is rotated forward to move the placing / moving frame 7 by one box toward the right standby section 42 (FIG. 14C), one box of the placing / moving frame 7 is obtained. Since the mounting space is located below the seedling box supply unit 22, the frame moving motor 20 is stopped, and then the supply motor 32 is energized to move the seedling box A by the seedling box supply unit 22 located on the right side. Supply (FIG. 14C), and when this is repeated (FIG. 14D,
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. 14F). Then
In this state, first, when the nursery box supply unit 22 is moved to the left, the stopper 43 in the retracted state, which was located on the upper surface of the innermost nursery box A, becomes an upright state after passing the end face of the nursery box A. It turns to be located substantially above the right rail 2 (FIG. 1).
4g). 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 32 is energized to supply only one nursery box A by the nursery box supply unit 22 (FIG. 14).
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. 14h). Again, the mounting moving frame 7
Is moved to the left by one box, the right seedling raising box A falls (FIG. 14), and the space of the left placement moving frame 7 faces below the seedling raising box supply section 22, so that the seedling raising box A is supplied. (Fig. 1
4 li), when this is repeated (nu, le, o, wa in FIG. 14),
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 not shown, the nursery box supply unit 2
2 is moved to the right, and the placing and moving frame 7 is moved to the right, the parallel operation of the nursery boxes in the first row is completed, and the next seedling box A is placed on the placing and moving frame 7 moved to the right. In this state, the traveling frame 4 is moved forward, and the above operation is repeated to perform the parallel work of the seedling boxes in the second and subsequent rows, and to arrange the seedling boxes A on both the left and right sides of the central rail 2. Can be. Therefore, when the placing / moving frame 7 moves from the one standby unit 42 to the other waiting unit 42, the seedling raising box A on the placing / moving frame 7 on the one standby unit 42 side is lowered, and the other waiting unit 4
Since the seedling raising box A is supplied on the placing / moving frame 7 on the second side, the work efficiency is improved. That is, only in the first row of the initial operation, the seedling raising box A is supplied on the placing / moving frame 7. In the second row, the seedling raising box A has already been supplied on the placing and moving frame 7, and the work efficiency is greatly improved. In addition, since the placing and moving frame 7 is configured to intermittently move by one box,
When the placement from the placing and moving frame 7 to the placing place 1 and the supply of the seedling raising box A to the placing and moving frame 7 are simultaneously performed, smooth and reliable operation can be performed. 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 nursery box supply section 22 is provided with the traveling frame 4
The shaft 45 is provided so as to be movable in the left-right direction with respect to the horizontal direction, and is moved left and right by an interval L which is a difference from the width of the seedling box A larger than the width of the rail 2. When the section 22 is moved right and left, each of the left and right stoppers 43 provided in the seedling box supply section 22 is positioned substantially above the left and right rails 2, and the innermost seedling raising section on the placement moving frame 7. Box A can be placed near rail 2. Therefore, the seedling box supply unit 22 can supply the seedling box A one by one, and if the stopper 43 for blocking the seedling box A on the left and right sides on the return path is provided, as described above, When the portion 22 is moved right and left, the innermost nursery 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 the 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 4.
Since the guide running roller 49 is fitted in the window hole 48, when the guide running roller 49 is fitted on the upper surface of the vehicle body lateral frame 5 and the seedling box supply unit 22 is placed, the seedling box supply unit 22 To the right and left. 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. Then
Although the configuration of the seedling box supply unit 22 is not a requirement, the operation of the seedling box supply unit 22 will be described in detail. When the placing / moving frame 7 is positioned in the above, the supply motor 39 is energized to rotate the transmission shaft 40, and the rotation of the transmission shaft 40 is controlled by the bevel gear 41 and the bevel gear 3.

Rotate 6.

The cam plate 36 moves the roller 34 up and down, whereby the rotation arm 33 rotates to rotate the mounting shaft 30 forward and reverse, and the seedling box A is supported by the forward and reverse rotation of the mounting shaft 30. The supporting member 31 is rotated 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 moving frame 7, and then moves from the retreat position T to the support position S. When the support member 31 returns to the position, the lowermost seedling raising box A is left on the placing / moving frame 7, and the flange 32 of the second lower seedling raising box A is placed.
, And are lifted to the support position S to be supported.
Therefore, the seedling raising boxes A can be supplied one by one to the placing and moving frame 7 one by one by the pair of front and rear support members 31, so that the structure is simple, the number of breakdowns is small, and the cost is reduced. That is,
In the state of supporting the seedling box A at the second tier from the bottom, the support of the upper and lower two sets of supporting and feeding mechanism for removing the support of the seedling box A at the lowermost stage is complicated, but the supporting member 31 of the present application has a simple driving mechanism. it can.

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
6 so as to be rotatable, and the shock absorbing rotation member 54 is provided.
Is configured to support the seedling raising box A on the outbound path for transferring the seedling raising box A and to rotate downward on the return path where the seedling raising box A is lowered, so that the return path moving toward the center side may interfere with the floor surface or the like. Instead, if it hits the convex part, it can turn upward and escape, and if it does not turn upward, it is located on the upward path where there is a risk of interfering with the floor surface or the like. In particular, when laying a root-cutting net in a field scene and placing the seedling raising box A on the net, the impact of falling is reduced and the net is prevented from being caught on the net. In addition, the shock absorbing rotation member 54
Is provided with a spring 58 that holds the shaft 56 as a dead point between the supporting position and the unloading position between the shock absorbing rotation member 54 and the placing and moving frame 7, so that the seedling raising box is surely provided at the supporting position. A is supported, and in a lowered position, careless upward rotation is prevented.

That is, when the seedling raising box A is lowered, the impact-relieving turning member 54 is rotated downward by the load on which the seedling raising box A is placed, and returns to the protrusion 59 provided on the traveling frame 4 to return to the final position. When the seedling raising box A is placed by the movement of the placement moving frame 7, the impact-reducing rotating member 54 is rotated downward about the shaft 56 by the load, so that the impact-relieving rotating member 54 is connected to the support position. When the rod 57 comes into contact with the protruding piece 55, the downward rotation stops, and at this time, the spring 58 suspended between the impact-reducing rotary member 54 and the mounting and moving frame 7 is positioned below the shaft 56. The nursery box A is slid and placed on the inclined shock absorbing rotating member 54 while holding the shock absorbing rotating member 54 beyond the so-called dead center. Therefore, since the impact of the fall is alleviated, the scattering of the soil and seeds in the seedling raising box A is prevented. And
When the placing / moving frame 7 moves on the return path toward the center side, the impact absorbing rotation member 54 is provided with a projection 59 provided on the traveling frame body 4 side.
The lower surface of the shock absorbing rotation member 54 comes back into contact with the lower surface of the shock absorber, and automatically returns to the original position. When the placing and moving frame 7 moves outward, it is located at the upper position and does not interfere with the floor surface or the like.

Thus, the seedling raising box A to which the soil is supplied is placed on the placing and moving frame 7, so that the soil is scattered. However, the moving rollers 12 provided on the placing and moving frame 7 have the flange portions 13 on both sides. The traveling frame 4 is formed with a pair of upper and lower square rail-shaped guide rails 1.
1 and 11 are provided, and the moving roller 12 is sandwiched between the upper and lower guide rails 11.
The soil that has fallen on the top 1 falls from the left and right sides to prevent the soil from accumulating. That is, when a cylindrical roller is fitted in a channel-shaped rail, the peripheral surface of the roller contacts the rail to properly support and guide the load, but it is very difficult to remove the soil once in the rail. However, in the present application, since the periphery is opened by a pair of upper and lower guide rails 11 and 11 having a rectangular axis shape, it is a moving roller 12 provided with a flange portion 13 while preventing the accumulation of soil, As with channel-shaped rails, it can be guided accurately. Further, the front and rear width of the placing and moving frame 7 can be arbitrarily configured.
Are arranged side by side in a horizontal direction. Therefore, even if the growth of the seedling raising boxes A on the left and right sides may be delayed in the seedling raising in the house, it is sufficient to remove the part and supply it to the rice transplanter. Do not waste. 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. Normally, since the innermost seedling raising box A is stopped by the stopper 43 and only the placement moving frame 7 is moved, the seedling raising boxes A to be placed are arranged side by side without any gap (FIGS. 14, 15, Reference numeral 16 denotes a gap between the adjacent seedling raising boxes A for the convenience of drawing.), And the traveling frame 4 has a front-rear direction at an interval larger than the interval of one seedling raising box A based on the left and right vehicle body side frames 6. The mounting rod 68 is not pivoted to the center side, but the upper part of the distance regulating stopper 69 is pivotally mounted on the shaft 70 so as to pivot outward. When the placement moving frame 7 is moved downward, the top of the seedling raising box A rotates upward when the leading end of the seedling raising box A comes into contact with the interval regulating stopper 69 while the placement moving frame 7 is moving forward. The moving frame 7 passes, but the end face of the seedling box A is restricted Since topper space restricting stopper 69 when contact 69 does not rotate in contact with the side face of the mounting rod 68, nursery box A in this position is kept stationary state, it is placed in the field. Therefore, each nursery box A
Are brought down to the field in contact with each of the interval regulating stoppers 69, so that the seedling raising boxes A can be juxtaposed with a gap provided between them. When one of the interval regulating stoppers 69 is selected and lowered, the entire seedling box A is moved to the interval regulating stopper 69.
Move under the forward path, and only the desired seedling raising box A comes into contact with the interval regulating stopper 69 on the return path, so that it can be placed at a desired interval.
