[Seedling box storage and transport shelf]
The seedling-raising box storage and transportation shelf 10 of FIGS. 1 and 2 has a plurality of shelves 2 that can store seedling-raising boxes P that are rectangular in plan view in multiple stages and rows. The seedling raising box storage and transportation shelf 10 includes a plurality of vertical bars 1a that extend vertically at intervals in the row direction (X direction in FIG. 1), and a plurality of vertical bars 1a that extend in the row direction and are connected to the upper ends of the plurality of vertical bars 1a. The frame body 1 includes a pair of frames 1 having an upper horizontal bar 1b and a lower horizontal bar 1c extending in the row direction and connected to the lower ends of the plurality of vertical bars 1a. The pair of frames 1 are arranged facing each other in the row direction (Y direction in FIG. 1).

The seedling raising box storage/transport shelf 10 includes a plurality of pairs of rod-shaped members 2a that are stretched between vertical bars 1a facing each other in the row direction at positions where the vertical bars 1a adjacent to each other in the column direction face each other. In the seedling-raising box storage and transportation shelf 10, a pair of frames 1 are connected by a plurality of pairs of rod-shaped members 2a, and each pair of rod-shaped members 2a constitutes a shelf section 2 in which a seedling-raising box P can be stored. . Moreover, the seedling-raising box storing and transporting shelf 10 further includes a transportation means capable of transporting the seedling-raising boxes P stored in the shelf section 2.

The seedling raising box storage and transportation shelf 10 is a frame member formed by connecting a pair of frames 1 to each other by a plurality of pairs of rod-shaped members 2a. To explain in more detail, the seedling raising box storage and transportation shelf 10 does not include a crosspiece whose sole purpose is to connect the pair of frames 1 to each other. For example, the seedling box storage and transportation shelf 10 does not include a crosspiece that is arranged between the shelf parts 2 adjacent in the row direction and connects the pair of frames 1 to each other. With this configuration, the seedling box storage and transportation shelf 10 can have a plurality of shelves 2 arranged densely in the row direction.

The frame body 1 has an intermediate horizontal bar 1d extending in the row direction between the upper horizontal bar 1b and the lower horizontal bar 1c. The plurality of vertical bars 1a, upper horizontal bars 1b, lower horizontal bars 1c, and intermediate horizontal bars 1d that constitute the frame 1 are connected by fasteners such as bolts and nuts. Further, the pair of frames 1 and the plurality of pairs of rod-shaped members 2a are connected by fasteners such as bolts and nuts. The bars (vertical bar 1a, upper horizontal bar 1b, lower horizontal bar 1c, and intermediate horizontal bar 1d) constituting the frame 1, and the pair of frame bodies 1 and the plurality of pairs of rod-shaped members 2a are L-shaped members, They may be connected via a connector such as a U-shaped member. The seedling raising box storage and transportation shelf 10 uses L-shaped members and U-shaped members, and by combining the 90-degree angles of these members, a plurality of members are fixed so as to be parallel or orthogonal to each other. Therefore, it has excellent strength.

The seedling raising box storing and transporting shelf 10 is arranged such that the rod-shaped member 2a is parallel to the longitudinal direction of the seedling raising box P. By being provided in this way, the seedling growing box storage and transportation shelf 10 can insert and pull out the seedling growing boxes P from the row direction (Y direction in FIG. 1). The seedling raising box storing and transporting shelf 10 includes a seedling raising box P (planting seedling tray) in which a plurality of seedlings that have been grown to a certain degree are arranged, a box storing a plurality of seedlings grown in pots, pots, etc. It is configured to store on one shelf 2 on a one-to-one basis (note that the objects stored on the seedling raising box storage and transportation shelf 10 are not particularly limited. For example, the seedling raising box storage and transportation shelf 10 is It is also possible to store seeding trays. In this case, it is also possible to store a plurality of seeding trays in a stacked manner on one shelf 2). In general, it is better to insert two seedling growing boxes sequentially in the transverse direction to one shelf than to insert one seedling growing box in the longitudinal direction to one shelf, which reduces the number of parts for the entire shelf. This makes it easier to reduce weight and cost. However, in a configuration in which the seedling box is inserted and stored in the transverse direction, the operator must hold the seedling box at a 90° angle before inserting the box into the shelf or after pulling the box out from the shelf. It takes time to rotate and change the container, and there is a risk that the seedling box may be dropped during this process. Further, the labor required by the operator increases when, for example, pulling out the rear seedling box that was inserted earlier. On the other hand, the seedling box storage and transportation shelf 10 is configured such that one seedling box P is stored in the longitudinal direction of the seedling box P on one shelf part 2, so that the seedling box P can be stored on the shelf. It is possible to facilitate the work of inserting the seedling box P into the section 2 and the work of pulling out the seedling raising box P from the shelf section 2, and to improve the safety of the work.

The rod-shaped member 2a is linear. Moreover, the rod-shaped member 2a has an L-shaped cross section perpendicular to its longitudinal direction. Thereby, the rod-shaped member 2a has a fixed piece fixed to the vertical bar 1a and a protruding piece that projects perpendicularly to the vertical bar 1a. The protruding piece functions as a support piece that supports the seedling raising box P from below.

A space is formed between the rod-shaped members 2a that constitute the shelf section 2. As a result, the seedling raising box storing and transporting shelf 10 stores the seedling raising boxes P in the shelf section 2 one step at a time, depending on the growth degree of the seedlings, for example, and uses the space on the upper shelf section 2 as a holding space for the seedlings. be able to.

Although the lower limit of the number of rows of shelf sections 2 in the seedling raising box storing and transporting shelf 10 is not particularly limited, from the viewpoint of improving the transport efficiency of the seedling raising boxes P, 4 is preferable, and 5 is more preferable. On the other hand, the upper limit of the number of rows is not particularly limited, but it is possible to easily place the seedling box storage/transport shelf 10 on a trolley, truck, etc., to load and unload in narrow passages inside and outside the nursery, From the viewpoint of workability such as loading work, length, width, height dimensions and maximum total weight, 7 is preferable, and 6 is more preferable. By setting the number of rows to 5 or 6, the seedling box storage/transport shelf 10 can be easily configured to a size that can fit into the bed of a truck. More specifically, in the case of the seedling raising box storing and transporting shelf 10, for example, when the number of rows is 5, and the planar dimensions of the seedling raising box P are 300 mm x 600 mm, the length of the frame 1 in the column direction is suppressed to 1800 mm or less. I can do it. This size is large enough to be loaded onto the bed of a light truck. According to this configuration, as will be described later, when the seedling growing boxes P are stored on the shelf 2, the seedling growing box storing and transporting shelf 10 can be easily moved by a forklift or the like from both sides of the light truck and from the rear. It can be loaded onto the bed of a truck or unloaded from the bed of a light truck.

The length of the seedling raising box storing and transporting shelf 10 in the row direction (Y direction in FIG. 1) can be set corresponding to the length of the seedling raising box P in the longitudinal direction. The seedling raising box storing and transporting shelf 10 can have its entire width (namely, the length in the row direction) corresponding to the length in the longitudinal direction of the seedling raising box P, so it is easy to make it compact. Specifically, the length in the row direction of the seedling raising box storage and transportation shelf 10 can be approximately 700 mm or less. This size is such that two seedling box storage and transportation racks 10 can be arranged in parallel to face each other in the row direction and loaded onto the platform of a light truck. According to this configuration, with the seedling growing boxes P stored in the shelf section 2, the seedling growing box storing and transporting shelf 10 can be easily loaded onto or unloaded from the loading bed of a light truck using a forklift or the like. .

The plurality of shelves 2 arranged on the seedling box storage and transportation shelf 10 are arranged in alignment in the row direction (X direction in FIG. 1) and the vertical direction (Z direction in FIG. 1). That is, the plurality of shelf sections 2 are arranged in alignment in the column direction at a plurality of height positions.

The number of shelves 2 in the seedling box storage and transportation rack 10 is not particularly limited, but it is suitable for improving the transportation efficiency of the seedling box P, loading and unloading in narrow passages inside and outside the nursery, and loading and unloading of boxes. From the viewpoint of workability such as vertical, horizontal, and height dimensions and maximum total weight, and from the viewpoint of constraints on the height of the house entrance, the number is preferably 3 to 8, more preferably 4 to 7, and 5 to 7. 6 is more preferred. Further, the upper limit of the number of shelves in the shelf section 2 is not particularly limited, but from the viewpoint of the handling of the seedling box storage/transport shelf 10 and restrictions on the height of the worker, 9 is preferable, and 8 is preferable. More preferred.

The seedling box storage/transport shelf 10 is arranged such that the uppermost shelf portion 2 protrudes above the upper horizontal rail 1b. In addition, in the seedling box storage and transportation shelf 10, a shelf 2 one level lower than the top shelf (second shelf 2) is arranged on the intermediate horizontal rail 1d. The seedling box storage/transport shelf 10 has a distance between the uppermost shelf 2 and the second shelf 2 one level below the same shelf 2, and a distance between the second shelf 2 and the second shelf 2 below it. The interval with the shelf part 3 (the third shelf part 2) is larger than the interval between the other shelf parts 2. Specifically, the distance between the top shelf 2 and the second shelf 2 is longer than the distance between the shelves 2 below the third shelf 2, which will be described later. The interval between the second shelf 2 and the third shelf 2 is larger than the interval between the shelves 2 below the third shelf 2. It is larger by the size of the crosspiece 1d. Note that the interval between the shelf parts 2 below the third shelf part 2 can be, for example, about 120 mm.

The seedling raising box storing and transporting shelf 10 has a support rod 3 that is removably arranged at the entrance of the seedling raising box P. The support rod 3 passes through the intermediate horizontal bar 1d in the vertical direction and is supported from below by the lower horizontal bar 1c. The lower horizontal beam 1c may be provided with a recess into which the support rod 3 fits. Furthermore, the seedling-raising box storing and transporting shelf 10 has a protrusion 4 that projects upward from the upper horizontal bar 1b and prevents the seedling-raising box P from falling from the uppermost shelf section 2. The seedling box storing and transporting shelf 10 uses projections 4 to prevent the seedling boxes P stored on the top shelf 2 from falling, and prevents the seedling boxes P stored on the shelf 2 below the top shelf from falling. The support rod 3 is configured to prevent this. According to this configuration, a space S (a space in which the support rod 3 is not arranged) can be provided between the top shelf 2 and the shelf 2 one step below the top shelf. This space S constitutes an insertion port for inserting a forklift claw, which will be described later, into the first insertion portion 5. As a result, while the projections 4 and the support rods 3 prevent the seedling growing boxes P stored in the shelf section 2 from falling, the seedling growing box storage shelf 10 can be easily transported by a forklift.

(Means of transportation)
As described above, the seedling-raising box storage and transportation shelf 10 includes a transportation means that can transport the seedling-raising boxes P stored in the shelf section 2. The seedling-raising box storing and transporting shelf 10 may be loaded onto a trolley, a truck, etc., and moved to a seedling nursery such as an open field or a greenhouse. At this time, it is preferable if the seedling raising box P can be reloaded onto a trolley, truck, etc. in a stored state, since it is possible to omit the work of reloading each seedling raising box P and to save the trouble of transporting each seedling raising box P. .

The seedling box storage and transportation shelf 10 has an insertion section (a first insertion section 5 and a second insertion section 6) into which a claw of a forklift can be inserted as the transportation means. With this configuration, the seedling-growing box storage and transportation shelf 10 can be easily placed on a trolley, truck, or the like using a forklift. Note that FIGS. 1 and 2 illustrate a configuration in which the seedling raising box storage and transportation shelf 10 has both the first insertion part 5 and the second insertion part 6. However, the seedling-growing box storage and transportation shelf 10 can also be configured to have only one of the first insertion part 5 and the second insertion part 6.

[First insertion part]
The first insertion part 5 is provided so that the claw of a forklift can be inserted in the row direction. The first insertion portion 5 is provided directly below the upper horizontal beam 1b. With this configuration, the weight of the seedling box storage and transportation shelf 10 below the first insertion part 5 is greater than the weight above the first insertion part 5. As a result, it can be easily and stably transported by a forklift.

The first insertion part 5 is provided between the uppermost shelf part 2 and the shelf part 2 one level below it. With this configuration, the number of shelves 2 can be increased and the shelves 2 can be easily and stably transported by a forklift.

In the seedling raising box storage and transportation shelf 10, the distance between the uppermost shelf 2 and the shelf 2 located one level below this shelf 2 is such that the interval between the shelf 2 on the lower side than the third shelf 2 is It is larger than the distance between them. More specifically, the distance between the top shelf 2 and the shelf 2 located one level below this shelf 2 is the distance between the shelves 2 below the third shelf 2. It is 60 mm or more and 120 mm or less larger than that, and preferably about 80 to 90 mm, which is the height of a typical pallet fork insertion. This space constitutes the first insertion section 5. Note that a specific distance between the shelf section 2 arranged at the top level and the shelf section 2 located one level below this shelf section 2 can be, for example, 180 mm or more and 250 mm or less.

In the seedling box storage and transportation shelf 10, the lower surface of the upper horizontal beam 1b is configured as a contact surface against which the claw of a forklift comes into contact. Further, the seedling box storage and transportation shelf 10 has a first reinforcing member 7 on the inner side in the direction in which the upper horizontal bars 1b of the pair of frames 1 face each other to support the claws of a forklift from above. The lower surface of the first reinforcing member 7, together with the lower surface of the upper horizontal beam 1b, is provided so as to come into contact with a claw of a forklift. With this configuration, the seedling box storage and transportation shelf 10 can be more easily and stably transported by a forklift while being maintained horizontally with respect to the ground.

[Second insertion part]
The second insertion part 6 is provided so that the claw of a forklift can be inserted in the row direction. Depending on the specifications of the truck, it may not be possible to insert the claw of the forklift in the row direction and place the seedling box storage/transport shelf 10 on the truck bed. Even in such a case, by having the second insertion part 6, the seedling raising box storage and transportation shelf 10 can be placed at a desired location. In addition, when inserting the forklift claw in the row direction, a sheath may be provided in the forklift claw. By doing so, the claw of a forklift can be easily inserted into the inside of the seedling box storage and transportation shelf 10 in the column direction.

The second insertion portion 6 is provided directly below the uppermost bar-shaped member 2a (that is, the uppermost shelf portion 2). With this configuration, the weight of the seedling box storage and transportation shelf 10 below the second insertion section 6 is greater than the weight above the second insertion section 6. As a result, it can be easily and stably transported by a forklift. Moreover, by providing both the first insertion part 5 and the second insertion part 6, it is possible to select the insertion direction of the forklift claw depending on the transportation space, the arrangement after transportation, and the like.

The second insertion part 6 is provided between the uppermost shelf part 2 and the shelf part 2 one level below it. With this configuration, the number of shelves 2 can be increased and the shelves 2 can be easily and stably transported by a forklift.

The seedling box storage/transport shelf 10 is configured such that the lower surface of the uppermost rod-shaped member 2a serves as a contact surface against which the claw of a forklift comes into contact. In addition, the seedling box storage/transport shelf 10 is spanned over a pair of upper horizontal bars 1b on the sides of the topmost rod-shaped member 2a (more specifically, on the outer sides in the row direction), and the claws of the forklift are placed in the upper direction. It has a second reinforcing member 8 that is supported from above. The lower surface of the second reinforcing member 8, together with the lower surface of the rod-shaped member 2a, is provided so as to come into contact with the claw of the forklift. With this configuration, the seedling box storage and transportation shelf 10 can be more easily and stably transported by a forklift while being maintained horizontally with respect to the ground.

(Other means of transportation)
The seedling box storage and transportation shelf 10 may have an engaging portion (not shown) that can be engaged with a lifting hook as another transportation means. This engaging portion may be provided together with the aforementioned insertion portion (the first insertion portion 5 and the second insertion portion 6), or may be provided instead of the aforementioned insertion portion. By having the above-mentioned engaging portion, the seedling box storage and transportation shelf 10 can be transported by a lifting device other than a forklift, such as a mobile crane or an overhead crane, and can be used for transshipment work between a trolley and a truck. . This engaging portion may be, for example, a ring piece. The arrangement of the ring pieces is not particularly limited; for example, they may be arranged only at one location in the structural center of the seedling box storage/transport shelf 10, or they may be arranged at both ends of the pair of upper horizontal bars 1b. However, in consideration of the inclination of the seedling box storage/transport shelf 10, truck, cart, etc. due to unevenness or inclination of the ground, it is preferable to suspend at one point. By having the above-described engaging portion, the seedling-growing box storage and transportation shelf 10 can be easily placed on a cart, truck, or the like using a lifting device.

The seedling raising box storage and transportation shelf 10 may have, as other transportation means, connecting portions (not shown) that are arranged at the ends of the pair of lower horizontal bars 1c and can be connected to the rotating tops. This connecting portion may have, for example, an insertion hole on the lower surface for connecting with the rotating top. According to this configuration, the seedling box storage and transportation shelf 10 can be self-propelled by being connected to the rotating top. As a result, although it is not suitable for long-distance movement, it can be optimally used for local movement in extremely narrow places.

The seedling box storage and transportation shelf 10 can be placed on the platform of a truck. The passageways in and around nurseries are often narrow, making it impossible for trucks and other vehicles to enter them. In this regard, the seedling nursery box storage and transport shelf 10 is configured so that it can be placed on the loading platform of a trolley, so that it can be easily moved to a seedling nursery or the like. Hereinafter, an example of a configuration in which the seedling box storage and transportation shelf 10 of FIG. 1 is arranged on the loading platform of a truck will be described.

(trolley)
The truck 30 shown in FIGS. 3 to 6 includes a loading platform 31 that is rectangular in plan view, a pair of wheels 32 that are arranged below the loading platform 31 and facing each other in the vehicle width direction (Y direction in FIG. 3), and the loading platform 31. The first leg portion 33 is disposed at the end of one side in the traveling direction (the right side in the X direction in FIG. 3; hereinafter, one side in the traveling direction is also referred to as the “first direction”) and projects below the loading platform 31. and a second side which is arranged at the end of the other side of the loading platform 31 in the traveling direction (left side in the X direction in FIG. It includes two leg parts 34 and a load support column 35 that protrudes upward from the end of one side (more specifically, the second direction side) of the loading platform 31 in the traveling direction.

As shown in FIG. 4, the bogie 30 is a two-wheeled bogie that can run only on a pair of wheels 32 facing each other in the vehicle width direction. Since the trolley 30 can run only on the pair of wheels 32, it can turn in a small radius. The trolley 30 travels with the loading platform 31 tilted so that the first leg 33 side is higher, for example, and the first leg 33 and the second leg 34 held so as to be spaced apart from the ground. The trolley 30 can be moved by, for example, a worker holding a part of the loading platform 31. That is, the operator may hold the end portion in the first direction, or may hold the end portion side in the second direction. Further, the trolley 30 may be configured such that one or both of the first leg portion 33 and the second leg portion 34 can be expanded and contracted. For example, when the first leg portion 33 is extendable and retractable, the trolley 30 may shorten the length of the first leg portion 33 during traveling so that the loading platform 31 is kept substantially horizontal. In this case, the length of the first leg 33 and the length of the second leg 34 during running are made approximately the same so that the distance between the first leg 33 and the second leg 34 and the ground is approximately equal. It is also preferable.

[Cargo platform]
The loading platform 31 is constructed using a frame made of a combination of a plurality of aggregates. As described above, the loading platform 31 has a rectangular shape in plan view, and more specifically, a rectangular shape whose longitudinal direction is the traveling direction. The loading platform 31 has a pair of side aggregates 31a extending in the running direction on both sides in the vehicle width direction.

The loading platform 31 has a flat plate shape. That is, the upper surface of the loading platform 31 is substantially flat. Since the loading platform 31 has a flat plate shape, it is easy to arrange the seedling box storage and transportation shelf 10 on the loading platform 31.

〔Wheel〕
The pair of wheels 32 are arranged at the center of the loading platform 31 in the traveling direction. For example, the rotation axes of the pair of wheels 32 may be arranged at the center position when the loading platform 31 is divided into two equal parts in the traveling direction.

On the other hand, it is also preferable that the rotation axes of the pair of wheels 32 are offset toward the second leg portion 34 (second direction) with respect to the center position of the loading platform 31 in the traveling direction. The rotation axes of the pair of wheels 32 are offset toward the second leg portion 34 side from the center position of the loading platform 31 in the traveling direction, so that the weight balance of the loading platform 31 is adjusted above or below the rotating shaft. It is easy to control so that the first direction becomes larger. As a result, by grounding the first leg portion 33, it becomes easier to stop the truck 30 stably.

[First leg]
As shown in FIGS. 3 and 6, the first leg portion 33 protrudes in a direction perpendicular to the horizontal plane (vertically downward) when the loading platform 31 is arranged parallel to the horizontal plane. Further, the first leg portion 33 is configured to be able to be held at least at a height that abuts the horizontal surface. The first leg portion 33 may be height-adjustable so that it can be held at a height where it contacts the horizontal surface.

The first leg portion 33 is provided so as to be in contact with the ground when the trolley 30 is stopped. That is, the first leg portion 33 is a stop leg for preventing unintended movement of the truck 30. The first leg portion 33 is thus provided as a stop leg, and can also function as means for preventing the loading platform 31 from falling during the arrangement work of the seedling box storage and transportation shelf 10.

It is preferable that the first leg portion 33 is disposed at a central portion on one side of the loading platform 31 in the traveling direction, or at both left and right sides (the central portion is shown in FIG. 6). With this configuration, the stability of the truck 30 in a state where the first leg portion 33 is in contact with the ground can be improved.

[Second leg]
As shown in FIGS. 3 and 5, the second leg portion 34 protrudes in a direction perpendicular to the horizontal plane (vertically downward) when the loading platform 31 is arranged parallel to the horizontal plane. Further, the second leg portion 34 is configured to be able to be held at least at a height spaced apart from the horizontal plane. By providing the second leg portion 34, the truck 30 can easily prevent the truck 30 from overturning and the cargo from collapsing without impairing the ease of travel of the truck 30.

The second leg portion 34 is configured to be height adjustable so that it can be held at a height where it contacts the horizontal surface. By holding the second leg portion 34 at a height that makes contact with the horizontal surface, it becomes easy to arrange the seedling box storage and transportation shelf 10 on the loading platform 31.

It is preferable that the second leg portion 34 is disposed at a central portion on the other side of the loading platform 31 in the traveling direction, or at both left and right sides (the central portion is shown in FIG. 5). With this configuration, the stability of the truck 30 in a state where the second leg portion 34 is in contact with the ground can be improved.

[Load support pillar]
The load support column 35 prevents the load and the like from falling unintentionally from the loading platform 31 when the truck 30 is traveling. The trolley 30 travels, for example, with the first leg 33 side lifted upward. At this time, since the load support column 35 is arranged on the side opposite to the first leg 33, it is possible to easily prevent the seedling box storage and transportation shelf 10 from falling from the second leg 34 side. . Further, the load support column 35 can also be used to align the seedling-growing box storage and transportation shelf 10 with respect to the loading platform 31 when the seedling-growing box storage and transportation shelf 10 is placed on the loading platform 31.

The load support column 35 projects above the loading platform 31 so as to be orthogonal to the loading platform 31. The protruding length of the cargo support column 35 can be, for example, 40 cm or more.

The load support column 35 may be removable from the loading platform 31, or may be fixed to the loading platform 31 in a manner that is difficult to attach to or detach from the loading platform 31.
