DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Fig. 1 shows a side view of a plant cultivation structure 10 according to an embodiment of the present invention as seen from the right, and Fig. 2 shows a rear view of the plant cultivation structure 10 as seen from the rear. In the drawings, the front of the plant cultivation structure 10 is indicated by an arrow FR, the left of the plant cultivation structure 10 is indicated by an arrow LH, and the upward direction is indicated by an arrow UP.

[0023] The plant cultivation structure 10 according to this embodiment is installed in a greenhouse (for example, a vinyl greenhouse) and is used to cultivate a plant 12 (for example, strawberries, see FIG. 2) in a greenhouse within the greenhouse.

[0024] 1 and 2, the plant cultivation structure 10 is provided with a plurality of supports 14, which are arranged at intervals in the front-rear direction. Support columns 14A are provided at the left and right ends of the supports 14 as support members, and the support columns 14A are erected so as not to be tilted and extend in the vertical direction. Support rods 14B are hung between the upper portions and vertical intermediate portions between the support columns 14A as support portions, and the support rods 14B extend in the left-right direction.

[0025] A cultivation shelf 16 is supported on the upper portion and the vertical middle portion of each of the supports 14, and extends in the front-rear direction. The left-right (width) center of the cultivation shelf 16 is located at the left-right center between the support columns 14A of the supports 14, and the cultivation shelf 16 is slightly inclined downward from both ends in the front-rear direction (longitudinal direction) toward the front-rear center.

[0026] A U-shaped cross-section cultivation gutter 16A is provided in the portion of the cultivation shelf 16 other than the upper portion, and the cultivation gutter 16A is open to the upper side. The cultivation gutter 16A is supported from below by the support rods 14B of the multiple supports 14, and the cultivation shelf 16 is supported by the multiple supports 14. A long rectangular cultivation plate 16B is provided in the upper portion of the cultivation shelf 16, and the cultivation plate 16B closes the cultivation gutter 16A from the upper side. A plurality of circular cultivation holes 16C (see FIG. 6) are formed through the left and right portions of the cultivation plate 16B, and the plurality of cultivation holes 16C are arranged at intervals in the front-rear direction.

[0027] The plant 12 is placed in a state in which it penetrates the cultivation hole 16C of the cultivation plate 16B, and the stem of the plant 12 extends from the upper side of the cultivation plate 16B (cultivation hole 16C). The root of the plant 12 extends from the lower side of the cultivation plate 16B (cultivation hole 16C), and the root of the plant 12 is inserted into the cultivation gutter 16A. 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).

[0028] A mounting body 18 (see FIG. 3B) is attached to each of the supports 14 except the rear end support 14. A mounting column 18A is provided at the left and right ends of the mounting body 18 as a mounting member, and the mounting column 18A extends in the vertical direction. A mounting rod 18B is hung between the mounting columns 18A in the vertical middle, and the mounting rod 18B extends in the left-right direction. The left and right mounting columns 18A are attached to the left and right support columns 14A of the support 14, respectively, between the support rods 14B of the support 14, so that the mounting body 18 is attached to the support 14 and disposed between the support columns 14A. The mounting rod 18B is removable from the pair of mounting columns 18A, and mounting rods 18B with different left-right (longitudinal) dimensions can be hung between the mounting columns 18A.

[0029] A rail 20 (see FIG. 3(B)) is attached to the upper side of the left-right center of each mounting rod 18B of the mounting bodies 18 as a guide, and the rail 20 extends in the front-rear direction along the longitudinal direction of the cultivation shelf 16. The left-right position of the rail 20 is located at the left-right center of the cultivation shelf 16, and the cross section of the rail 20 is elongated in the up-down direction. The rail 20 is not provided at the rear of the cultivation shelf 16 in the front-rear direction, and the rear end of the rail 20 is located forward of the rear end of the cultivation shelf 16. A plate-shaped convex portion 20A (see FIG. 5(A)) is formed to protrude from the left and right ends of the upper part of the rail 20, and the outer surface of the convex portion 20A is curved in a convex shape toward the outside of the left-right direction of the rail 20 in the up-down direction.

[0030] A damper 22 (see FIG. 5(B)) serving as a stopping part is provided above the front end of the rail 20. The damper 22 is provided with a cylindrical stopping rod 22A serving as a stopping member, and the stopping rod 22A is movable in the front-rear direction within a predetermined range. The stopping rod 22A is coaxially inserted into a spring 22B (compression coil spring) serving as an absorbing member, and the spring 22B urges the stopping rod 22A rearward.

[0031] Two sliders 24 (see Figures 3(A) and 4(A)) are slidably supported on the upper side of the rail 20. The two sliders 24 are each elongated in the front-to-rear direction and aligned in the front-to-rear direction.

[0032] The slider 24 is provided with a slider body 26 in the shape of a substantially rectangular parallelepiped box as a main body member, and the inside of the slider body 26 is open on the top, front, and rear sides. A support plate 26A in the shape of a substantially rectangular plate is provided at the rear end of the lower part (bottom) of the slider body 26 and at the intermediate part (front side) in the front-rear direction, and the support plate 26A is disposed at the center part in the left-right direction of the slider body 26. Three rollers 28 (see Figs. 4(B) and 5(A)) in the shape of a substantially cylindrical plate as a rotating part are supported on the lower side of the support plate 26A, and the rollers 28 are rotatable around the up-down direction. Two rollers 28 and one roller 28 are provided on the left and right sides of the front support plate 26A, and the position of the right roller 28 in the front-rear direction is the center position between the left rollers 28 in the front-rear direction. The rear support plate 26A is provided with one roller 28 on the left side and two on the right side, with the left roller 28 being positioned in the front-rear direction central position between the right rollers 28. A recess 28A having a substantially trapezoidal cross section is formed around the entire circumference at the axial middle portion of the roller 28, and the axial dimension of the recess 28A increases toward the radial outside of the roller 28.

[0033] Between the recessed portion 28A of the left roller 28 and the recessed portion 28A of the right roller 28 in the front and rear support plates 26A, the upper portion of the rail 20 (including the protruding portion 20A) is fitted in the left-right direction, whereby the slider body 26 is supported in the left-right direction by the rail 20. The protruding portion 20A of the rail 20 is fitted in the top-bottom direction by the recessed portion 28A of each roller 28, whereby the slider body 26 is supported in the top-bottom direction by the rail 20. Therefore, the slider 24 (slider body 26) is guided by the rail 20 and is slidable in the front-rear direction, and when the slider 24 slides in the front-rear direction, each roller 28 is rotated by the frictional force between the rail 20. The left-right (width) dimension of the slider 24 is smaller than the left-right dimension of the gap between the mounting posts 18A of the mounting body 18, and the slider 24 is slidable in the front-rear direction passing between the mounting posts 18A.

[0034] The front-to-rear distance between the rearmost support 14 and the rear end of the rail 20 is slightly larger than the front-to-rear distance between the rear end of the slider body 26 and the second-from-front roller 28 (which can be the frontmost roller 28). This makes it possible to insert the rear end of the rail 20 between the left and right rollers 28 of the slider body 26 forward of the rearmost support 14, and also makes it possible to remove the rear end of the rail 20 from between the left and right rollers 28 of the slider body 26, thereby making it possible to attach and detach the slider body 26 to and from the rail 20.

[0035] A substantially cylindrical closing pillar 26B (see FIG. 7) is provided as a closing member at the rear right corner of the slider body 26, and the closing pillar 26B is rotatable around the lower end in the front-rear direction within a predetermined range. The closing pillar 26B is rotated to a closing position to the left (inside the slider body 26) and downward, and the closing pillar 26B closes the rear opening in the slider body 26. The closing pillar 26B is rotatable to an opening position to the upward, whereby the closing pillar 26B opens the rear opening in the slider body 26.

[0036] The left part of the rear end of the lower part of the slider body 26 of the front slider 24 and the left part of the front end of the lower part of the slider body 26 of the rear slider 24 are connected by a connecting post 30 (see FIG. 7) having a substantially rectangular column shape as a connecting member, whereby the front slider 24 and the rear slider 24 are connected and made slidable together. The connecting post 30 is detachable from the front slider body 26 and the rear slider body 26, and the connection between the front slider 24 and the rear slider 24 is released by detaching the connecting post 30 from the front slider body 26 and the rear slider body 26.

[0037] A substantially rectangular abutment plate 32 serving as an abutment member is removably attached to the front side of the slider body 26 of the front slider 24, and the abutment plate 32 closes the front opening in the slider body 26. When the abutment plate 32 abuts against the stop rod 22A of the damper 22 while the front and rear sliders 24 are slid forward, the forward movement of the stop rod 22A is elastically restricted by the biasing force of the spring 22B of the damper 22, and the forward sliding of the front and rear sliders 24 (including the abutment plate 32) is stopped.

[0038] A substantially rectangular box-shaped workbench 34 (see FIG. 6) is accommodated in the slider body 26 as a container, and the workbench 34 is made of transparent resin and has an upper opening. The workbench 34 is fitted in the slider body 26 in the left-right direction, and the forward movement of the workbench 34 relative to the slider body 26 is restricted by the abutment plate 32 in the front slider 24, and restricted by the closing pillar 26B of the front slider body 26 in the rear slider 24. The rearward movement of the workbench 34 relative to the slider body 26 is restricted by the closing pillar 26B of the slider body 26, and when the closing pillar 26B is rotated to the upper open position, the workbench 34 is allowed to move rearward relative to the slider body 26 (see FIG. 8(A)). The lower end of the rear wall 34A (closing portion) of the workbench 34 is supported by the rear end of the lower wall of the workbench 34 (see FIG. 7), and the rear wall 34A of the workbench 34 is rotatable rearward around the lower end. The rearward rotation of the rear wall 34A of the workbench 34 is restricted by the closing pillar 26B of the slider body 26, and the rear wall 34A of the workbench 34 closes the rear side of the interior of the workbench 34. When the closing pillar 26B is rotated to the upper open position, the rear wall 34A of the workbench 34 is rotatable rearward, and the interior of the workbench 34 is made open rearward (see FIG. 8(A)).

[0039] A rectangular plate-shaped sheet 36 (see Figs. 6 and 7) serving as a removable member is placed on the underside of the workbench 34, and the sheet 36 is generally fitted into the workbench 34 in the left-right and front-rear directions. A rectangular plate-shaped protrusion 36A is integrally formed on the rear side of the sheet 36, and the protrusion 36A protrudes rearward. When the rear wall 34A of the workbench 34 is rotated rearward, the sheet 36 can be moved rearward relative to the workbench 34 with the protrusion 36A pinched.

[0040] A plurality of (six in this embodiment) roughly rectangular box-shaped trays 38 (see Figs. 6 and 8(B)) are accommodated within the workbench 34 as storage members, and the trays 38 are placed on the sheet 36 with the interiors open at the top. The longitudinal direction of the trays 38 is the left-right direction and the width direction of the trays 38 is the front-rear direction, and the plurality of trays 38 are fitted into the workbench 34 in their respective longitudinal directions and are arranged in their respective width directions. The trays 38 are adapted to accommodate plants 12 (fruits 12A of the plants 12 in this embodiment) from the upper opening.

[0041] Next, the operation of this embodiment will be described.

[0042] In the plant cultivation structure 10 configured as described above, the cultivation shelves 16 are arranged vertically, and rails 20 extend along the longitudinal direction (front-rear direction) of the cultivation shelves 16, and the sliders 24 are guided by the rails 20 to slide. Furthermore, the plants 12 are movable between the cultivation shelves 16 and the sliders 24, and in this embodiment, the fruits 12A of the plants 12 on the cultivation shelves 16 are moved to the trays 38 of the sliders 24 and stored in the trays 38. Therefore, by sliding the sliders 24, the plants 12 can be easily moved between the sliders 24 along the entire longitudinal direction of the cultivation shelves 16.

[0043] Here, the rails 20 extend between the upper and lower cultivation shelves 16. This allows plants to be moved between the sliders 24 and the upper and lower cultivation shelves 16, eliminating the need to provide the rails 20 and sliders 24 for each cultivation shelf 16, simplifying the configuration and reducing space and costs.

[0044] Furthermore, the support 14 not only supports the cultivation shelf 16, but also supports the rail 20 via the mounting body 18. Therefore, the rail 20 can be supported with a simple structure.

[0045] Furthermore, support columns 14A of the support body 14 are arranged on both sides in the width direction (left and right direction) of the cultivation shelf 16, and the slider 24 slides between the support columns 14A. Therefore, the slider 24 can slide without being hindered by the support columns 14A.

[0046] Further, the mounting body 18 is attached between the support columns 14A of the support body 14, and the slider 24 slides between the mounting columns 18A on both the left and right sides of the mounting body 18. Therefore, the slider 24 can slide without being hindered by the mounting columns 18A.

[0047] Furthermore, in the mounting body 18, the mounting rod 18B between the mounting posts 18A is made removable from the mounting posts 18A. Therefore, by removing the mounting rod 18B from the mounting posts 18A and replacing it, the longitudinal dimension of the mounting rod 18B can be adjusted, and the left-right dimension between the mounting posts 18A can be adjusted. This makes it possible to mount the mounting body 18 to the support body 14 even if the left-right dimension between the support posts 14A of the support body 14 is changed.

[0048] In addition, the front and rear sliders 24 are connected by a connecting column 30. Therefore, the front and rear sliders 24 can be slid simultaneously, and the longitudinal range of the cultivation shelf 16 in which the plants 12 can be moved between the stopped sliders 24 can be increased.

[0049] Furthermore, a plurality of trays 38 are provided on the slider 24, and the plants 12 (fruits 12A) can be accommodated in the trays 38. Therefore, the plants 12 can be divided into individual trays 38.

[0050] Moreover, in the slider 24, the closing pillar 26B of the slider body 26 restricts the rear wall 34A of the workbench 34 from rotating rearward, and the sheet 36 is placed on the lower surface of the workbench 34, and multiple trays 38 are placed on the sheet 36. Therefore, by rotating the closing pillar 26B to the upper open position and rotating the rear wall 34A of the workbench 34 rearward, and then moving the sheet 36 rearward relative to the workbench 34 while pinching the protruding portion 36A of the sheet 36, it is possible to remove the sheet 36 from the slider 24 and move the multiple trays 38 together with the sheet 36 at the same time.

[0051] In this embodiment, two cultivation shelves 16 are provided in the vertical direction. However, three or more cultivation shelves 16 may be provided in the vertical direction. In this case, rails 20 and sliders 24 may be provided between each cultivation shelf 16.

[0052] Furthermore, in this embodiment, two sliders 24 are connected. However, three or more sliders 24 may be connected, or no sliders 24 may be connected. [Explanation of symbols]
