In the cultivation gutter 16A, the culture solution flows down from both ends in the front-rear direction toward the center in the front-rear direction, so that the culture solution is supplied to the root of the plant 12, and the plant 12 is cultivated. The culture solution that reaches the center in the front-rear direction in the cultivation gutter 16A is transported to both ends in the front-rear direction in the cultivation gutter 16A via a transport pipe (not shown).

[0027] As shown in Fig. 1 and Fig. 3, the plant cultivation structure 10 is provided with a plurality of installation bodies 18 (see Fig. 4), and the plurality of installation bodies 18 are arranged at intervals in the front-rear direction in the arrangement range in the front-rear direction of the cultivation shelf 16. Installation columns 18A as installation members are provided at the left and right ends of the installation body 18, and the installation columns 18A are erected so as not to be tilted and extend in the vertical direction. Connecting rods 18B as connecting members are hung between the upper and lower parts between the installation columns 18A, and the connecting rods 18B extend in the left-right direction. The left and right installation columns 18A are respectively arranged outside the left and right support columns 14A of the support body 14 in the left-right direction, and the connecting rods 18B are arranged below the cultivation shelf 16.

[0028] Rails 20 (see FIG. 4) are attached as guides to the upper ends and vertical middle parts of the installation posts 18A on the left and right sides of the installation bodies 18, and the rails 20 have a cross section elongated in the left-right direction and protrude outward in the left-right direction of the installation bodies 18. The rails 20 extend in the front-rear direction along the longitudinal direction of the cultivation shelf 16, and the rails 20 are slightly inclined downward from both ends in the front-rear direction (longitudinal direction) toward the central part in the front-rear direction. Plate-shaped convex parts 20A (see FIG. 6) are formed to protrude from the upper and lower ends of the left-right outer parts of the installation bodies 18 of the rails 20, and the outer surfaces of the convex parts 20A are curved in a convex shape toward the vertical outer side of the rails 20 in the left-right direction.

[0029] A slider 24 (see FIGS. 8 and 10) is slidably supported on each of the pair of rails 20 on the left side and the pair of rails 20 on the right side, on the outer side of the installation body 18 in the left-right direction.

[0030] The slider 24 is provided with a slider body 26 (see Figs. 4 and 5) in the shape of a substantially rectangular frame as a main body member, and a plurality of substantially cylindrical rollers 28 as rotating parts are provided at the upper and lower ends of the slider body 26. At the upper end of the slider body 26, eight and four rollers 28 are provided on the upper and lower sides, respectively, spaced apart in the front-rear direction, and at the lower end of the slider body 26, five and two rollers 28 are provided on the upper and lower sides, respectively, spaced apart in the front-rear direction. The rollers 28 protrude toward the rail 20, and the rollers 28 are rotatable in the left-right direction. At the axial middle part of the roller 28, a recess 28A (see Fig. 6) having a substantially trapezoidal cross section is formed around the entire circumference, and the axial dimension of the recess 28A of the roller 28 increases toward the radially outward side of the roller 28.

[0031] Between the recesses 28A of the upper roller 28 and the recesses 28A of the lower roller 28 at the upper and lower ends of the slider body 26, the outer portions (including the protrusions 20A) of the installation bodies 18 of the upper and lower rails 20 are fitted in the vertical direction, so that the slider body 26 is supported on both sides in the vertical direction by the rail 20. The protrusions 20A of the rail 20 are fitted in the horizontal direction into the recesses 28A of each roller 28, so that the slider body 26 is supported on both sides in the horizontal direction by the rail 20. Therefore, the slider 24 (slider body 26) is guided by the upper and lower rails 20 and is slidable in the front-rear direction, and when the slider 24 is slid in the front-rear direction, each roller 28 is rotated by the frictional force between the rail 20.

[0032] A hook bar 26A as a hooked portion is integrally provided on the upper side of the slider body 26, and the hook bar 26A extends in the front-rear direction. A lock bar 26B as a locking portion is integrally provided on the front and rear ends of the hook bar 26A, and the lock bar 26B protrudes toward the rail 20.

[0033] A roughly rectangular box-shaped carriage 30 (see FIG. 7) serving as an arrangement body can be attached to the slider body 26, and the interior of the carriage 30 is open to the top and one side in the front-rear direction. A U-shaped rod-shaped protruding frame 30A is integrally provided on the upper end of the other side in the front-rear direction of the carriage 30 on the rail 20 side, and the protruding frame 30A protrudes to the other side in the front-rear direction and the inside is connected to the interior of the carriage 30.

[0034] A plurality of wheels 30B (see FIG. 1) (four in this embodiment) are rotatably supported on the underside of the dolly 30, and the wheels 30B are arranged at the front left corner, the front right corner, the rear left corner, and the rear right corner of the dolly 30. The dolly 30 is supported on the ground via the wheels 30B, and the dolly 30 can slide in the front-rear direction by rotating the wheels 30B.

[0035] A plurality of (four in this embodiment) hooks 30C in the form of a substantially L-shape rod are provided on the upper portion of the carriage 30 on the rail 20 side as hooking portions, and the base end side portions of the hooks 30C protrude toward the rail 20 side, while the tip side portions of the hooks 30C protrude downward. The base ends of the plurality of hooks 30C are connected, and the plurality of hooks 30C are movable together in the vertical direction within a predetermined range. The plurality of hooks 30C are moved upward and then downward, and are hooked from above onto the hook rods 26A of the slider body 26, so that the carriage 30 can be attached to the slider body 26 (see FIG. 8). The tip side portions of the plurality of hooks 30C are disposed between the lock rods 26B of the hook rods 26A, so that the relative sliding of the carriage 30 in the front-rear direction with respect to the slider body 26 is restricted, and the slider body 26 and the carriage 30 are slidable together in the front-rear direction. Near the base end of the hook 30C, an abutment bar 30D is integrally provided as an abutment portion, and the abutment bar 30D protrudes downward. When the carriage 30 is attached to the slider body 26, the hook bar 26A of the slider body 26 is disposed between the abutment bar 30D and the tip end portion of the hook 30C, so that the abutment bar 30D and the tip end portion of the hook 30C can abut against the hook bar 26A, and the movement of the carriage 30 in the left-right direction relative to the slider body 26 is restricted. At the connecting portion of the base ends of the multiple hooks 30C, a U-shaped rod-like gripping frame 30E is integrally provided, and the gripping frame 30E protrudes upward.

[0036] A storage bag (not shown) can be placed inside the dolly 30 as a storage member, and an open end of the storage bag is hooked onto the upper end of the dolly 30, making the inside of the storage bag open to the upper side of the dolly 30. The inside of the storage bag can accommodate the plants 12 and the like (e.g., waste from the plants 12) through the opening.

[0037] A substantially rectangular parallelepiped box-shaped basket 32 ​​(see FIG. 9) serving as an arrangement body can be attached to the slider body 26, and the inside of the basket 32 ​​is open on the top side and on both front and rear sides.

[0038] At the upper end of the carriage 30, on the rail 20 side, a plurality of hooks 32A (four in this embodiment) in the shape of a substantially L-shape rod are provided as hooking parts, and the base end side portion of the hook 32A protrudes toward the rail 20 side, and the tip side portion of the hook 32A protrudes downward. The middle portions of the plurality of hooks 32A are connected, and the plurality of hooks 32A are immovable relative to the cage 32. The plurality of hooks 32A are hooked from above onto the hook rod 26A of the slider body 26, and the side surface of the cage 32 abuts against the slider body 26, so that the cage 32 can be attached to the slider body 26 (see FIG. 10). The tip side portions of the plurality of hooks 32A are disposed between the lock rods 26B of the hook rod 26A, so that the relative sliding of the cage 32 in the front-rear direction with respect to the slider body 26 is restricted, and the slider body 26 and the cage 32 can slide together in the front-rear direction.

[0039] A storage box (not shown) can be placed inside the basket 32 ​​as a storage member, and the inside of the storage box is open at the top, allowing it to be opened above the basket 32. The storage box allows the plants 12 and the like (for example, fruits of the plants 12, accessories) to be stored from the top opening.

[0040] Next, the operation of this embodiment will be described.

[0041] In the plant cultivation structure 10 configured as described above, the rails 20 extend in the longitudinal direction (front-rear direction) of the cultivation shelf 16 on both sides in the width direction (left-right direction) of the cultivation shelf 16, and the slider 24 is guided to slide by the rails 20. Furthermore, the plants 12, etc. are made movable between the cultivation shelf 16 and the slider 24, and for example, the plant 12 on the cultivation shelf 16 is moved to the carriage 30 or the basket 32 ​​of the slider 24 and stored (placed) in the storage bag of the carriage 30 or the storage box of the basket 32. Therefore, by sliding the slider 24, the plants 12, etc. can be easily moved between the slider 24 and the slider 24 over the entire longitudinal direction of the cultivation shelf 16.

[0042] Here, on the left and right sides of the cultivation shelf 16, rails 20 are provided on the upper and lower sides, and the slider 24 (slider body 26) is guided in sliding by the pair of rails 20. Therefore, the slider 24 can be appropriately guided, and the slider 24 can be slid stably, improving the sliding operability of the slider 24.

[0043] Furthermore, the sliders 24 are slidable on the left and right sides of the cultivation shelf 16. Therefore, even when the plants 12 are cultivated on the left and right sides of the cultivation shelf 16, the plants 12 etc. can be smoothly moved between the left side of the cultivation shelf 16 and the left slider 24 and between the right side of the cultivation shelf 16 and the right slider 24.

[0044] Furthermore, the pair of rails 20 on the left side and the pair of rails 20 on the right side are connected to each other by the installation body 18. This makes it possible to easily install the pairs of rails 20 on the left side and the right side.

[0045] Furthermore, the cultivation shelf 16 is supported by the support body 14, and each pair of rails 20 is supported by the installation body 18, and each pair of rails 20 is installed independently of the cultivation shelf 16. Therefore, the cultivation shelf 16 can be installed independently of the support body 14 and the cultivation shelf 16, and the installation position of each pair of rails 20 can be freely selected.

[0046] In addition, the longitudinal direction of the cultivation shelf 16 is slightly inclined with respect to the front-rear direction (horizontal direction), and a pair of rails 20 extend along the longitudinal direction of the cultivation shelf 16, with the extension direction of the pair of rails 20 being slightly inclined with respect to the front-rear direction. Therefore, even when the longitudinal direction of the cultivation shelf 16 is inclined with respect to the front-rear direction, the pair of rails 20 can maintain the vertical interval and can guide the slider 24.

[0047] Furthermore, the slider 24 is supported by the rail 20 by vertically clamping the rail 20 between upper and lower rollers 28 at the upper and lower ends of the slider body 26. This allows the rail 20 to appropriately support the slider 24 (slider body 26).

[0048] Furthermore, the hook 30C of the cart 30 or the hook 32A of the basket 32 ​​is hooked onto the hooking rod 26A of the slider body 26, and the cart 30 or the basket 32 ​​is attached to the slider 24. This allows the cart 30 and the basket 32 ​​to be easily attached to the slider 24, and allows the components attached to the slider 24 to be easily exchanged between the cart 30 and the basket 32. Moreover, the left-right dimension of the hooking structure of the hook 30C or the hook 32A to the hooking rod 26A can be reduced, thereby allowing the left-right dimension of the plant cultivation structure 10 to be reduced.

[0049] Furthermore, the hook 30C of the carriage 30 is made movable in the vertical direction. Therefore, by slightly inclining the extending direction of the pair of rails 20 with respect to the front-rear direction, even if the vertical position of the slider body 26 is changed by sliding the slider body 26 relative to the pair of rails 20, the hook 30C can be moved in the vertical direction to maintain the state in which the hook 30C is hooked on the hook rod 26A of the slider body 26, and the carriage 30 can be maintained attached to the slider body 26.

[0050] Furthermore, in the case where a plurality of plant cultivation structures 10 are arranged in the left-right direction (see FIG. 1), when the dolly 30 or the basket 32 ​​is attached to the slider body 26 of one plant cultivation structure 10 on the side of the other plant cultivation structure 10, the dolly 30 and the basket 32 ​​cannot be attached to the slider body 26 of the other plant cultivation structure 10 on the side of the one plant cultivation structure 10. This allows an operator to pass between the dolly 30 or the basket 32 ​​of one plant cultivation structure 10 and the other plant cultivation structure 10 in the forward and backward directions.

[0051] Furthermore, when the carriage 30 is attached to the slider body 26, an operator can enter the side of the protruding frame 30A of the carriage 30 opposite the rail 20. Therefore, the space on the side of the carriage 30 opposite the rail 20 can be made larger.

[0052] In this embodiment, the rollers 28 are provided on both the upper and lower sides of the rail 20 on which the slider body 26 is supported. However, the rollers 28 may be provided on only one of the upper and lower sides of the rail 20 on which the slider body 26 is supported, and the rollers 28 do not have to be provided on both the upper and lower sides of the rail 20 on which the slider body 26 is supported.

[0053] Furthermore, in this embodiment, the rollers 28 are provided on the slider body 26. However, the rollers 28 may be provided on the rail 20.

[0054] In this embodiment, the slider body 26 is supported on both left and right sides by the upper rail 20 and the lower rail 20. However, the slider body 26 may be supported on one side in the left and right direction by either the upper rail 20 or the lower rail 20.

[0055] Furthermore, in this embodiment, the slider body 26 is supported on both the up-down direction sides by the upper rail 20 and the lower rail 20. However, the slider body 26 may be supported on one side in the up-down direction by one of the upper rail 20 and the lower rail 20, or the slider body 26 may be supported on one side in the up-down direction by the upper rail 20 and on the other side in the up-down direction by the lower rail 20.
