DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a seedling raising box after seeding, wherein a predetermined number of seedling raising boxes are stacked to form a plurality of seedling raising groups, and the seedling raising groups are stacked by a predetermined number on a budding cart or budding pallet. Further, the present invention relates to a seedling raising facility in which seedling boxes in the seedling raising boxes are housed in a germination room while covering a seedling raising box located at the uppermost stage of each seedling raising box group.

[0002]

2. Description of the Related Art Conventionally, in a nursery facility as described above ,
When the seedlings in each seedling box are germinated under temperature and humidity control by storing a plurality of seedling boxes in which a series of seeding steps such as floor soil supply, sowing, and cover soil supply have been completed in a germination room, A predetermined number (for example, 30) of the seedling boxes are stacked in close contact with each other to form a plurality of seedling box groups, and the seedling box groups are arranged in a predetermined number (for example, four) on a budding cart or budding pallet. The seedling boxes supplied with only soil (so-called discard boxes) are placed in close contact with the seedling boxes located at the top of each group of seedling boxes, and the top of each seedling box is removed. By covering the seedlings, the germination conditions (temperature / humidity) for the seeds of the seedling boxes (the uppermost seedling raising box and the other seedling raising boxes) accommodated in the germination room were set to be the same. Thereby, the seeds in each seedling raising box can be germinated uniformly and favorably.

[0003]

However, according to the above prior art, the same number of disposal boxes as the plurality of seedling boxes to be accommodated in the germination room are prepared (only soil is supplied to the seedling boxes to produce the disposal boxes). Because it takes time and effort to place one dump box for each nursery box located at the top of each nursery box group,
There was room for improvement in reducing the labor required for raising seedlings.

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the labor required for seedling raising work by not using discard boxes, but also to establish germination conditions (temperature and humidity) for seeds in each seedling box housed in a germination room. ) Is made the same so that the seeds in each seedling raising box can germinate uniformly and well.

[0005]

To achieve the above object, according to the first aspect of the present invention, a predetermined number of seedling raising boxes formed by stacking a predetermined number of seedling raising boxes after sowing .
A budding cart or pallet on which the group is loaded
The seedling cart or the seedling box on which the seedling box group of
A budding room for storing bud pallets and the top row of each seedling box group
Together and a lid covering the nursery boxes located, said top
Was formed in a size covering a plurality of the seedling box groups.

According to the first aspect of the present invention, the seedling raising box located at the uppermost stage of each seedling raising box group is housed in the budding room in a state of being covered with a lid, so that the seedling raising box is not used. Even when the seedlings are stored in the seedling boxes (the uppermost seedling raising box and the other seedling raising boxes), the germination conditions (temperature and humidity) for the seeds can be the same. In addition, since it is not necessary to prepare a disposal box along with this, it is not necessary to supply only soil to the seedling raising box to make a disposal box. In addition, since the lid is formed to have a size covering a plurality of seedling box groups, one lid can cover a plurality of uppermost seedling raising boxes at a time. This eliminates the need to place one dump box at a time on the nursery box located at the top of the box, and also eliminates the need to prepare the same number of dump boxes as the plurality of seedling box groups housed in the sprouting room.
In addition, since the lid body does not use soil like a discard box, there is no inconvenience of generating mold and disease no matter how many times it is used.

[0007] Therefore, by employing a lid having a size covering a plurality of seedling box groups instead of discarding boxes, it is possible to make the germination conditions (temperature and humidity) for the seeds in each seedling box the same. In addition, the seeds in each seedling raising box can germinate uniformly and favorably, the labor required for the seedling raising operation can be reduced, and the occurrence of mold and disease can be suppressed.

According to the second aspect of the present invention,
In addition to the first aspect of the present invention, the lid has a positioning engaging portion that engages with a plurality of seedling box groups in which the uppermost seedling raising box is covered by the lid.

According to the second aspect of the invention, the plurality of seedling box groups in which the uppermost seedling raising box is covered by the lid is positioned by engaging with the engaging portion provided on the lid. At the same time, the upper portions are connected to each other via the lid, and support each other. That is,
The fall of each seedling box group is suppressed by another seedling box group connected via the lid.

[0010] Therefore, by making a simple improvement by simply providing the cover with the engaging portion, the cover covers the seedling box located at the uppermost stage of the plurality of seedling box groups. Fall can now be prevented.

[0011] In the invention according to claim 3 of the present invention,
In addition to the invention described in claim 1 or 2, the lid is provided in the budding chamber so as to be able to move up and down.

According to the third aspect of the present invention, since the lid is provided in the germination chamber so as to be able to move up and down, the time required for placing or removing the lid from the uppermost seedling raising box is reduced. can do. Also, there is no need to provide a place for placing the lid. Moreover, a large-sized one that covers the entire area of the germination chamber can be adopted as the lid, and the raising and lowering operation of the lid allows the nursery box located at the top of the group of all the nursery boxes housed in the germination chamber to be seen at once. It becomes possible to cover. In addition, when the lid is placed on the seedling box at the uppermost stage, by applying an appropriate downward pressure to the seedling box group, the falling of each seedling box group can be reliably prevented. Become.

Therefore, the labor required for the seedling raising operation can be further reduced, and the work efficiency when placing the lid on the uppermost seedling raising box can be improved.
In addition, the nursery box group can be reliably prevented from overturning.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic configuration of a seedling raising facility. In this seedling raising facility, the seedling raising boxes 1 are taken out one by one from an empty seedling raising box group 2 in which 30 empty seedling raising boxes 1 are stacked. Automatic feeding device A to be supplied, seeding plant B and seeding plant B for transporting each seedling box 1 supplied from the automatic feeding device A while performing a series of seeding steps such as floor soil supply, sowing, and covering soil supply. The seedling raising boxes 1 for which the seeding process has been completed are stacked in a state in which 30 seedling raising boxes 1 are adhered to each other (a state in which the bottom of the upper seedling raising box 1 is fitted in the lower seedling raising box 1) to form a seedling raising box group 3 and a budding cart. An automatic stacking device C for transferring the seedlings to the seedling box group 3 conveyed by the germination cart 4; a germination chamber D for germinating the seeds in each seedling box 1 under temperature and humidity control; From budding trolley 4 taken out from budding room D The seedling box group 3 is taken out, and the seedling boxes 1 of the seedling box group 3 are automatically stacked on the greening cart 5 at a distance of about 15 cm on the greening cart 5, and each seedling transported by the greening cart 5 The greening room F in which the boxes 1 are housed together with the greening carts 5 to green the seedlings in each seedling raising box 1 under the control of temperature, humidity and light intensity, and the greening carts 5 taken out of the greening room F from the respective greening carts 1 And a hardening house G for curing the green planted seedlings on the ground under temperature and humidity control.

As shown in FIG. 2, the four seedling raising box groups 3 are loaded on each germination cart 4 by the automatic stacking device C in a state of being arranged vertically and horizontally, and the seedling raising box groups 3 are turned over. A fall prevention rod 4A for preventing the fall is provided detachably. The seedling raising box 1 located at the uppermost stage of each seedling raising box group 3 loaded on the germination trolley 4 has a size corresponding to each seedling raising box group 3 loaded on the germination trolley 4 (over the four seedling raising box groups 3). The cover 6 having a plate-like shape and having air permeability is formed. That is, each seedling box group 3 loaded on the germination cart 4 is accommodated in the germination room D in a state where the top seedling raising boxes 1 are covered with one lid 6. Incidentally, as a method of giving the lid 6 air permeability, the lid 6 may be formed of a material having excellent air permeability, or a vent hole may be formed of a material having poor or no air permeability. There is a method.

As described above, the seedling raising boxes 1 housed in the germination room D are covered with the seedling raising boxes 1 stacked on the seedling raising boxes 1 or the lids 6 placed on the seedling raising boxes D. The seeds in each seedling box 1 can be made to have the same germination condition (temperature and humidity) when they are accommodated in the seedling D and germinated, so that the seeds sown in each seedling box 1 can be evenly and favorably distributed. They can germinate. In addition, since the lid 6 is placed on the seedling raising box 1 at the top, a discard box (one in which only soil is supplied to the seedling raising box 1) is placed on the seedling raising box 1 at the top. In comparison with the above, there is no need to make a discard box, and since the lid 6 is formed in a size that covers each seedling box group 3 loaded on the budding cart 4, four lids are formed by the placement. Since the uppermost seedling raising box 1 can be covered all at once, a waste box or lid of the size of one seedling raising box is placed on each of the uppermost raising seedling boxes 1. This saves time and effort such as preparing the same number of discard boxes and lids as the plurality of seedling box groups 3 housed in the germination room D. Therefore, the labor required for the seedling raising operation can be reduced. Moreover,
Since the lid body 6 does not use soil like a discard box, it does not have the inconvenience of generating mold and disease no matter how many times it is used. Therefore, it is possible to suppress the occurrence of mold and disease.

[Other Embodiments] Hereinafter, other embodiments of the present invention will be listed. As the seedling raising facility, the seedling box 1 is supplied to the seeding plant B, the seedling raising box 1 after sowing is transferred to the germination trolley 4, and the seedling raising box 1 is replaced with the greening trolley 5 from the seedling trolley 4. The budding pallet may be used instead of the budding trolley 4. The number of seedling boxes 1 forming one seedling box group 3, the number of seedling box groups 3 loaded on one budding cart 4, and
The number of germination trolleys 4 or budding pallets accommodated in one germination room D can be variously changed according to the size of the germination room D, the germination trolley 4 or the germination pallet. The lid 6 can be variously modified as long as it is formed in a size that covers a plurality of the seedling box groups 3. For example, the size that covers the two seedling box groups 3 (in the above-described embodiment). In the case where four seedling raising box groups 3 are loaded on one germination cart 4 as described above, the size covers half of the seedling raising box groups 3). The size of the seedling box group 3 or the size of the eight seedling box groups 3 (in the case of loading four seedling box groups 3 on one seedling cart 4 as in the above embodiment, germination (The size of the nursery box group 3 for four trolleys). The cover 6 may be urged toward the uppermost seedling raising box 1 by a spring or the like. As shown in FIGS. 3 and 4, a positioning engaging portion 6 </ b> A that engages with a plurality of seedling box groups 3 in which the top of the seedling raising box 1 is covered by the lid 6 is provided on the periphery of the lid 6. As an example, a peripheral wall portion 6a surrounding the plurality of seedling raising box groups 3 in which the uppermost seedling raising box 1 is covered by the lid 6 may be provided. In the case where the lid 6 is formed in this manner, even if the sprout cart 4 is not provided with the fall prevention rod 4A, the inward fall of each seedling box group 3 is caused by the contact between the seedling box groups 3 and The fall of each seedling box group 3 to the outside can be suppressed by the peripheral wall 6a of the lid 6. In FIGS. 3 and 4, the peripheral wall portion 6 a is provided in a state of covering the entire peripheral edge of the lid 6. However, the peripheral wall portion 6 a may be provided in a state of being intermittently connected to the peripheral edge of the lid 6. Good. As shown in FIGS. 5 and 6, an example of a positioning engaging portion 6 </ b> A that engages with the plurality of seedling box groups 3 in which the lid 6 covers the uppermost seedling raising box 1. Alternatively, an inner wall portion 6b may be provided to be fitted in a plurality (four in FIG. 5) of the uppermost seedling raising boxes 1 covered by the lid 6. When the lid 6 is formed in this manner, the inner wall portion 6b of the lid 6 can prevent the seedling box group 3 from falling inward and outward even if the germination cart 4 does not include the fall prevention rod 4A. become. As shown in FIG. 7, the lid 6 may be provided in the germination chamber D so as to be able to move up and down. In this configuration, it is possible to reduce the time and effort required for placing or removing the lid 6 with respect to the seedling raising box 1 at the top, and to reduce the time required for the lid 6.
It is no longer necessary to provide a place for storing. Moreover, if the lid 6 is formed so as to cover the entire area of the germination chamber D as shown in the same figure, the uppermost stage of the whole seedling box group 3 accommodated in the germination chamber D by the raising / lowering operation of the lid 6. Can be covered all at once. In addition, when the lid 6 is placed on the seedling raising box 1 at the uppermost stage, if an appropriate downward pressure is applied to the seedling raising box group 3, it is possible to prevent the seedling raising group D from being housed in the germination room D. Of the seedling box group 3 can be reliably prevented. In addition, the code | symbol 7 shown in FIG.
This is an elevating device that moves up and down between a state of being placed on the uppermost seedling raising box 1 and a state of being separated upward from the uppermost seedling raising box 1. As the elevating device 7, for example, as shown in FIG.
