Then, when one placement space for one box is opened on the left side, the seedling box A on the right side is lowered and placed (FIG. 9C). When the placement moving frame 10 is moved to the left by one box again, the seedling raising box A on the right lowers (FIG. 9).
Re), since the space of the left placement moving frame 10 faces below the seedling box supply part 17, the seedling box A is supplied (FIG. 9R),
When this is repeated (FIG. 9 nu, ru, o, wa), the seedling box A is placed on the placing place 1 on the right side of the rail 2 while the placement moving frame 10 is moved to the left to supply the seedling box A. I do.

Next, although not shown, the nursery box supply unit 1
7 is moved to the right, and the placing and moving frame 10 is moved to the right, the parallel operation of the seedling boxes in the first row is completed, and the next seedling box A is placed on the placing and moving frame 10 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 and moving frame 10 moves from one of the right and left sides of the rail 2 to the other side, the seedling raising box A on the placing and moving frame 10 is lowered to one side (except for the first row first row). ), Since the seedling box A is newly supplied on the placing and moving frame 10, the work efficiency is improved, that is, the seedling box A is supplied on the placing and moving frame 10 only in the first row of the initial operation. For this reason, it is necessary to move the placement moving frame 10, but at the time of the second row, the seedling raising box A has already been supplied onto the placement moving frame 10, and the work efficiency is greatly improved. In addition, since the placement moving frame 10 is configured to intermittently move by one box, the seedling raising box A can be prevented from shifting with respect to the placement moving frame 10 and can be moved smoothly and reliably. Also, it is possible to smoothly and surely place the object from the mounting moving frame 10 to the mounting place 1.

Although the seedling box supply section 17 is formed to have a width larger than the width of the rail 2, when the seedling box supply section 17 is moved right and left, the left and right seedling raising sections provided in the seedling box supply section 17 are provided. Each of the box stopping devices 18 is located substantially above the left and right rails 2, and the innermost nursery box A on the placement moving frame 10 can be placed near the rail 2. In the embodiment, the nursery box supply unit 17 switches the moving position of the nursery box supply unit 17 left and right by manual operation, but a motor may be used.

In this case, the seedling raising box A in the forward movement is in contact with the inclined plate 20 and lifts the stopper 22 to pass therethrough. However, during the backward movement, the seedling raising box A is stopped in contact with the stopper end face 19. Further, since the mounting plate 23 is formed to be long in the forward movement direction of the seedling box A (outward direction away from the rail 2), when the seedling box A descends from the placement moving frame 10 by contacting the stopper 22, the seedling box A The end of the abutment abuts on the lower surface of the mounting plate 23 to restrict the natural fall and reduce the impact of the descent.

Further, a pair of front and rear mounting plates 108 are disposed on the vehicle body lateral frame 5 of the traveling frame 4 at intervals substantially equal to the width of the seedling raising box A with reference to the seedling raising box stopping device 18. 108
Is a stopper end face 11 that comes into contact with the seedling raising box A during the return trip.
2 is provided, the seedling raising box A on the placing / moving frame 10 is stopped by the stopper end face 112 and is blocked by the stopper end surface 112, and is placed at a predetermined position. Of the seedling box A is abutted against the lower surface of the mounting plate 108 so that natural fall is restricted, the impact of the descent is reduced, and the inner end of the seedling raising box A is prevented from being lifted, and the seedling raising box A overlaps with the next seedling raising box A. To prevent That is, the inner nursery box A
If only the seedling raising box A is blocked, the end of the next seedling raising box A may fall under the raised seedling raising box A, but this is prevented, and the seedling raising box A is securely placed at a predetermined position. In addition, the mounting moving frame 1
When 0 moves on the outward path, the end face of the seedling raising box A hits the inclined plate 113 and is rotated upward to be retracted. Since the sliding surface 114 slides on the upper surface of the side wall of the seedling raising box A, the seeding surface is not disturbed.

In the embodiment, the seedling raising boxes A are placed in the order of right and left in the figure. Therefore, the box detecting device 50 is provided on the vehicle body side frame 6 of the left running frame 4, and the box detecting device is provided. 5
0 is shorter than the upper horizontal plate 51 to form the lower horizontal plate 53, and the detector 56 is configured such that the contact portion 55 always rotates toward the rail 2 by its own weight. Detector 6
0, the seedling raising box A is pushed by the inclined plate 54 and pivots upward, and the tip of the seedling raising box A slides down on the inclined plate 54 and descends, and a detection object is placed on the outer surface (side surface) of the seedling raising box A. When the detecting portion 60 detects the upper horizontal plate 51 approaching the window 59, and then the traveling frame 4 is moved forward by another switch, the contacting portion 55 contacts. The part 55 slides on the end face of the seedling raising box A, and when the abutting part 55 passes through the end face of the seedling raising box A, the detecting body 56 rotates downward by its own weight around the shaft 58 and becomes in a standby state, and becomes a standby state. 51 departs from the detecting unit 60 and automatically stops the traveling of the traveling frame 4. In this case, since the detection body 56 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.

However, since the net rollers 62 for root cutting are provided on the front side of the vehicle body lateral frame 5 of the traveling frame 4 located on the left and right sides of the rail 2, the traveling frame 4 moves forward. At this time, a net is laid, and the nursery box A is placed thereon. At this time, the net roller 62
Since it is attached to the left and right frames 63 positioned lower than the lower row, when the row of seedling raising boxes A is laid, the traveling frame 4 is moved backward once, the left and right frames 63 are moved against the seedling raising boxes A, and are moved backward. The seedling box A is brought into contact with the seedling raising box A, and then is advanced again. Therefore, the seedling raising box A can be laid back and forth without any gap. That is, since the seedling raising box A is laid below the traveling frame 4, when the seedling raising box A is lowered in consideration of the width of the rear body lateral frame 5, the seedling raising box A is placed between the seedling raising box A and the already laid seedling raising box A. There is no gap, but doing so is troublesome and reduces work efficiency, so a gap may be created below,
This gap is easily filled.

The box detecting device 50 and the left and right frames 63 of the net roller 62 are combined with each other to improve the working efficiency without waste. In addition, on both the left and right sides of the placing and moving frame 10, there are provided shock absorbing rotating members 30 for reducing the impact of the descent when the placing and moving frame 10 is lowered onto the placing surface (ground, floor, etc.). When the seedling raising box A is supplied by the seedling raising box supply unit 17, the engagement shafts 3 on the right and left sides of the rotating plate 31 are provided.
8 is engaged with the hook portion 42 of the engaging hook 39, so that the box-shaped seedling raising box A having a heavy weight can be reliably supported,
Transfer to the end.

Next, when moving to the end side, the guide portion 43 above the engagement hook 39 hits the unlocking body 44, but passes through without being unlocked because the hook portion 42 rotates in the upward direction. When the placement moving frame 10 starts returning movement to lower the seedling raising box A and the unlocking body 44 comes into contact with the guide portion 43, it is rotated about the shaft 41 to rotate the hook portion 42 and the engagement shaft 38. The lock is released, and the rotating plate 31 is rotated downward by the weight of the seedling raising box A, and the descent of the seedling raising box A is made smooth. When passing below the seedling box supply section 17, the rotating plate 31 comes into contact with a contact body 45 provided in the moving path and rotates upward to be in a horizontal state. The shaft 38 engages with the hook portion 42 and is held in this state.
The next seedling box A is placed and transferred.

The operation of the seedling box supply unit 17 will now be described. As shown in FIG.
Are raised above the frame body 67, and in this state, the seedling raising boxes A stacked vertically by any means such as a lift device.
Is inserted between the left and right seedling raising box supports 76, and then the supply motor 95 is energized to rotate the pinion gear in the gear box 94 by the supply motor 95, and the pinion gear is inserted into the rack groove 92 of the vertical movement shaft 93. And raises the vertical movement shaft 93, the vertical movement engagement plate 90 provided on the vertical movement shaft 93 raises the movable frame support portion 91, and the seedling box support 76 is the rib 86 of the seedling raising box A at the lowermost stage. Then, in this state, any means such as a lift device is pulled out from below the lowermost seedling raising box A, and the supply of the stacked seedling raising box A is completed.

Next, when a supply switch (not shown) is pressed, the vertical movement shaft 93 is lowered by the supply motor 95, and the vertical movement shaft 93 lowers the movable frame support portion 91. When the movable frame support 91 is lowered, the movable frame 69 supported by the movable frame support 91 is lowered, and by the lowering of the movable frame 69, the entire left and right support arms 75 are lowered. That is, the load applied to the seedling box support 76 acts to rotate the support arm 75 outward, thereby acting to raise the engaging shaft 89, and moves upward and downward above the engaging shaft 89. Since there is a vertically movable engagement plate 90 provided on the shaft 93, the engagement shaft 89 is in an immobile state in contact with the lower surface of the vertically movable engagement plate 90, and this state is maintained without opening the support arm 75. At this time, since the spring 98 is provided between the engagement shafts 89, the support state of the support arm 75 is more reliably maintained.

Next, the seedling raising box A at the lowermost stage is
The lower surface of the lower horizontal frame 96 of the movable frame 69 abuts against the stopper 97 to stop the downward movement of the movable frame 69, and the vertical movement engagement plate 90 is moved by the movable frame support 91 from the movable frame support 91. As the vertical moving shaft 93 moves down, the vertical moving engaging plate 90 pushes the engaging shaft 89 from above.
Pivots downward about the axis 74, the support arm 75 pivots outward about the axis 74, and the seedling box support 76 of the support arm 75 retreats from the rib 86 of the seedling raising box A at the lowermost stage. Further, the timer plate 99 comes into contact with the upper end surface of the timer longitudinal axis 101 by the lowering of the support arm 75, and the timer longitudinal axis 101 descends as it is against the elasticity of the spring 103. And
When the support arm 75 is opened outward, the engagement hole 100 of the timer plate 99 faces above the timer longitudinal axis 101, and the timer longitudinal axis 101 protrudes upward through the engagement hole 100 by the elastic force of the spring 103.

However, the timer longitudinal axis 101 is
00, the supply motor 95 is rotated in the reverse direction,
The vertical moving shaft 93 moves upward, and the vertical moving engaging plate 90 comes into contact with the lower surface of the moving frame support portion 91 and moves upward. As described above, the timer longitudinal axis 101 is engaged with the engaging hole by the elastic force of the spring 103. Since the support arm 75 protrudes upward inside the support arm 75, the support arm 75 moves upward while the support arm 75 is in the retracted state. Next, when the seedling box support 76 of the support arm 75 is positioned beside the seedling box A at the second level from the bottom, the upper end of the timer longitudinal axis 101 is disengaged from the engagement hole 100, and the support arm 75 is moved to the spring-upper vertical plate. Closed by the elasticity of 40 (although there are other factors such as the weight of the support arm 75), the seedling box support 76 engages with the second seedling box A from the bottom, and the lowermost seedling box A is directly Then, the stacked seedling raising box A is lifted, and when the lowermost seedling raising box A placed on the placement moving frame 10 reaches a height at which it can be transferred, the raising is stopped.

In this case, when the seedling box support 76 of the support arm 75 passes through the lower surface of the rib 86 of the lowermost seedling box A, the upper end of the timer longitudinal axis 101 is set to be disengaged from the engagement hole 100. The support arm 75 is closed, the seedling box support 76 moves upward while sliding on the side surface of the rib 86 of the lowermost seedling box A, and closes when it passes over the upper surface of the rib 86,
In this state, the rib 86 of the seedling box A of the second tier from the bottom rises.
And raise the stacked seedling raising box A except for the lowermost seedling raising box A as it is. Therefore, even if there is some difference in the vertical width of the nursery box A, it can be used without readjustment.
That is, the seedling raising box support 76 is moved up and down between two points, the lowest position where the lowermost seedling raising box A is placed, and the standby position where the lowermost seedling raising box A can pass. Since the whole seedling raising box A is lifted together with the seedling raising box A of the step, the setting is easy and the operation is accurate.

The seedling box support 76 is shown in FIGS.
As shown in FIG. 9, an insertion hole 78 is formed in the case 77, a support rod 79 is inserted into the insertion hole 78 so as to freely enter and exit, and a spring 80 is provided on the support rod 79 so as to always protrude.
In accordance with the wall shape of the seedling raising box A, the necessary supporting rods 79 protrude and the unnecessary supporting rods 79 are retracted, so that the range that does not need to be adjusted is further widened and can be adapted to various seedling raising boxes A. When the height of the stopper 97 provided on the frame body 67 side is changed,
The opening height of the support arm 75 can be changed, and the
To the height of the Further, since the timer plate 99 is vertically attached to the support arm 75, when the timer plate 99 is moved up and down, the height at which the timer longitudinal axis 101 comes out of the engagement hole 100 can be changed. A different seedling raising box A can be supplied. When the thickness is small, the timer plate 99 is set high, and when the thickness is large, the timer plate 99 is set low.

Although not shown, a switch or a sensor is provided in the vicinity of the moving path of the moving frame 69 or in the vicinity of the vertical moving shaft 93 so as to be freely changeable in position. At the same time, the stop and forward / reverse rotation of the motor 95 are controlled. Since the support arm 75 and the rotation arm 88 are respectively fixed to the pair of left and right shaft cylinders 73 in the front-rear direction, the front side is open, and the seedling raising box A can be supplied from this open portion, and operability is improved. In addition, the workability is improved, and the structure is simple, trouble-free, easy to manufacture, and low in cost. In addition, since the support arm 75 and the rotating arm 88 are respectively fixed to the pair of left and right shaft cylinders 73 in the front-rear direction, the weight of the seedling raising box A with respect to opening and closing of the support arm 75 is reasonable. The load can be well supported.

The frame 67 of the seedling box supply section 17
The mounting plate 23 of the seedling box stopping device 18 is fixed to the one side surface 116 and the other side surface 117 inside the inside, and the stopper 22 is mounted on the mounting plate 23 by the shaft 25, and the movement stopping protrusion 26
Is arranged so that the stopper 22 is positioned outside the rail 2 by the distance L in the left-right direction. Therefore, since the seedling box stopping device 18 is provided inside the frame body 67, The moving amount can be reduced, and the working efficiency is improved.

Can be laid so that there is no waste of space, and the efficiency can be improved. According to the present invention, when the plurality of seedling raising boxes A of the traveling frame 4 are placed on the loading place 1, the detection of the box 56 of the box detecting device 50 provided on one of the right and left sides of the traveling frame 4 is performed. Is brought into contact with the side surface of the seedling raising box A on the end side, and then the traveling frame 4 is advanced, and when the detection body 56 passes through the seedling raising box A, it is separated from the side surface of the seedling raising box A. Since it is a method of laying nursery boxes in parallel so that running is automatically stopped by detecting that there is no
Box detection device 50 provided on one of the left and right sides of the traveling frame 4
, So that there is no obstacle to the supply of nursery boxes, etc.
This has the effect of being able to detect accurately with a simple method. The present invention relates to a seedling box in which, when the detection body 56 passes through the seedling box A, it rotates inside the seedling box A laid by its own weight, detects that there is no seedling box A, and automatically stops running. Since it is a parallel laying method, when it passes, it turns inside the nursery box A laid by its own weight and detects that there is no nursery box A, so it can be implemented by a simple method and implementation is easy. This has the effect of reducing costs. According to the present invention, an end of a sheet or net of a root cutting sheet or a net roller 62 provided in front of a traveling frame body 4 traveling on a rail 2 in the front-rear direction provided on a mounting place 1 is stopped at the mounting place 1. Then, a plurality of seedling raising boxes A are supplied to the traveling frame body 4 in a horizontal line, and the plurality of seedling raising boxes A are placed on a sheet or a net of the loading place 1. Then, when the detection frame 56 is moved forward by moving the traveling frame 4 and the detection body 56 passes through the seedling raising box A, it is separated from the side surface of the seedling raising box A to detect the absence of the seedling raising box A and travels. Is automatically stopped, and then the plurality of seedling boxes A in the second row are supplied to the traveling frame 4 in one horizontal row, and the plurality of seedling boxes A in the second and subsequent rows are placed on the sheet or the net of the loading space 1. When it is placed, the detection body 56 is brought into contact with the side surface of the seedling raising box A on the end side, and then the traveling frame 4 is moved backward to temporarily move it. Net roller 6 the front of each nursery box A was laying
2 is pushed rearward by the frame 63, and then the traveling frame 4
Is advanced, and when the detection body 56 passes through the seedling box A, it is separated from the side surface of the seedling box A, detects that there is no seedling box A, and automatically stops running. Therefore, the operability can be improved by stopping the running with reference to the seedling raising box on the end side, and the running frame 4 is moved backward to eliminate the front and rear gaps. The effect that can also be improved is produced. In the present invention, the traveling frame 4 is mounted on a side portion of a traveling frame 4 that can be laid in a row in the storage 1 by running on a rail 2 in the front-rear direction provided on the loading space 1. Since a box detecting device 50 for detecting passage of the seedling box A placed forward and placed is provided, and the running of the running frame 4 is automatically stopped, the seedling box parallel laying device is used. When the seedling boxes are placed in a row and moved forward, the stopping operation is facilitated, and the operability and the operability are improved. In the present invention, the traveling frame 4 includes the rail 2
A plurality of seedling raising boxes A laid on one side of the rail 2 can be placed, and the left and right traveling frames 4 on the rail 2 can be alternately reciprocated and placed on the traveling frame 7 provided on the traveling frame 4. A seedling box supply unit 17 that can supply the seedling boxes A one by one to the placing / moving frame 7 that is provided at the center of the running frame 4 and located below;
And a seedling box stopping device 18 provided on both the left and right sides of the seedling box supply unit 17 and passing the placing and moving frame 7 but not passing the seedling box A on the placing and moving frame 7. The device 50 is a parallel-laying device for raising seedling boxes provided on the side where the placement moving frame 7 is placed on the side on which the seedling raising box A is to be placed later, on the left and right sides of the traveling frame body 4. It is easy to lay a nursery box on both sides and move it forward by one box, which makes it possible to effectively use the mounting space, reduce the working space, do not hinder the supply of nursery boxes, etc., and have a simple configuration This has the effect of being able to detect accurately. According to the present invention, the box detecting device 50 is configured such that an upper portion of the detecting body 56 is rotatably mounted on a fixed portion by a shaft 58, and a contact portion 55 at a lower portion of the detecting body 56 is a side surface of the laid seedling raising box A. The detection body 56 is configured to be positioned on the rail 2 side by its own weight.
0 When it comes into contact with the side surface of the seedling raising box A descended from above and passes the side surface of the seedling raising box A sliding forward by moving the traveling frame 4, it turns downward by its own weight and confirms that there is no seedling raising box A. Since it is a nursery box parallel laying device configured to automatically stop the traveling of the traveling frame body 4 upon detection, it is detected without contact with the nursery box in a normal off state without using a spring or the like. With such a configuration, there is an effect that the configuration is simple, the assembly is easy, and the cost can be reduced. According to the present invention, a mounting plate 57 having a window 59 is provided at a predetermined position of the traveling frame 4 above the laid seedling raising box A, and a detection unit 6 is provided above the window 59.
0, the detection unit 60 is in contact with the side surface of the seedling box A on which the contact portion 55 of the detection body 56 is laid through the window 59, and the traveling frame 4 is moved forward. It is a nursery box parallel laying device configured to detect that it has passed through the side surface of the nursery box A and has returned under its own weight, and to automatically stop the traveling of the traveling frame 4. With the rational configuration in which the detection unit 60 is provided above the above, there is an effect that the device can be easily mounted without interfering with the movement of the seedling raising box and the device can be reduced in size. The present invention provides a root cutting sheet or net roller 62 in front of the traveling frame 4 via a frame 63 that is long in the left-right direction.
Since the frame 63 is a seedling box parallel laying device arranged lower than the height of the seedling box A, not only can the operability be improved by stopping the running with reference to the seedling box on the end side, but also Since the running frame 4 is moved backward and the seedling box is pushed rearward with the frame 63 arranged lower than the height of the seedling box A to eliminate the front and rear gaps, there is no waste of space and the efficiency is improved. Therefore, the number of parts does not change and the cost is not increased simply by arranging the seedling raising box A at a height lower than the height of the seedling raising box A.
