[0026] In the following description, the up-down direction, the left-right direction, and the front-rear direction are defined according to the arrows shown in the drawings.

[0027] Hereinafter, a plant cultivation device 1 according to one embodiment of the present invention will be described.

[0028] The plant cultivation device 1 shown in Fig. 1 and Fig. 2 is for cultivating a plant S. The plant cultivation device 1 of this embodiment is used in greenhouse horticulture, in which a plant S is cultivated using a facility such as a vinyl greenhouse. The facility is equipped with a ventilation system, an air conditioning system, and a carbon dioxide supplying device (e.g., a carbon dioxide gas generator, a gas cylinder, etc.), and the plant cultivation device 1 is provided within the facility. The plant cultivation device 1 includes a cultivation bed 10, a support member 20, a gas tube 30, a vinyl sheet 40, and a clip 50.

[0029] The cultivation bed 10 is a member for cultivating a plant S in a location separate from soil. As shown in FIG. 2, the cultivation bed 10 includes a main body 11 and a tray 12. The main body 11 is formed in a box shape with an open top. As shown in FIGS. 1 and 2, the main body 11 includes a bottom 11a, a left wall 11b, a right wall 11c, a front wall 11d, and a rear wall 11e. The main body 11 stores a nutrient solution Y, which is liquid fertilizer diluted with water.

[0030] The tray 12 shown in FIG. 2 is for supporting the plant S. The tray 12 is made of, for example, polystyrene foam. The tray 12 is formed in a rectangular plate shape and fixed to the main body 11. In this embodiment, gaps are formed between the left wall 11b and the right wall 11c and the tray 12. Note that the tray 12 is omitted from the perspective views such as FIG. 1. The tray 12 is formed with holes penetrating vertically, and the roots of the plant S are immersed in the nutrient solution Y through the holes (not shown). In this manner, in this embodiment, the plant S is grown hydroponically.

[0031] The cultivation bed 10 is placed on a cultivation bench and is disposed at a position higher than the ground (for example, at waist height). Thus, in this embodiment, the plant S is cultivated by elevated cultivation. Note that the cultivation method of the plant S is not limited to this embodiment (hydroponic cultivation and elevated cultivation). For example, the plant S can also be cultivated at the same height as the ground (by placing the cultivation bed 10 on the ground).

[0032] 1 and 2 is for supporting the gas tube 30. The support member 20 is formed in a generally inverted U-shape with an open lower portion. Two support members 20 are provided along the longitudinal direction (front-rear direction in this embodiment) of the gas tube 30. As shown in FIG. 2, the support member 20 includes an extension portion 21, a connection portion 22, and a protrusion portion 23.

[0033] The extension portion 21 is formed so as to extend in the up-down direction. The extension portion 21 is formed in a rod shape. The extension portion 21 is placed on the bottom portion 11a of the cultivation bed 10 and disposed so as to protrude upward from the cultivation bed 10. A pair of the extension portions 21 is formed on the left and right.

[0034] The left extension portion 21 is disposed between the tray 12 and the left wall portion 11b in the left-right direction (on the left side of the plant S when viewed from the front). A gap SK is formed between the left extension portion 21 and the left wall portion 11b (inner surface). The right extension portion 21, like the left extension portion 21, is disposed between the tray 12 and the right wall portion 11c, and a gap SK is formed between the right wall portion 11c.

[0035] 1 is disposed rearward of the front wall 11d of the main body 11. The rear support member 20 (extension 21) is disposed forward of the rear wall 11e. Thus, a gap SK is formed between the front wall 11d and the rear wall 11e and the extension 21, similar to the left wall 11b. In this manner, in this embodiment, a gap SK is formed on the outer side (front-rear and left-right outer sides) of the extension 21, and the gap SK can be used to place other members between each wall (left wall 11b, etc.) of the main body 11 and the extension 21.

[0036] 2, the pair of extension parts 21 each come into contact with the tray 12. This suppresses the movement of the support member 20 relative to the cultivation bed 10.

[0037] The connecting portion 22 is a portion that connects the upper ends of the pair of extending portions 21. The connecting portion 22 is formed in a rod shape. The connecting portion 22 is formed so as to extend in the left-right direction above the plant S. The connecting portion 22 has a recess 22a. The recess 22a is formed so as to be recessed downward at a left-right midpoint of the connecting portion 22.

[0038] The protrusions 23 are formed so as to protrude outwardly to the left and right from the lower ends of the pair of extending portions 21. The left protrusion 23 abuts against the left wall portion 11b. The right protrusion 23 abuts against the right wall portion 11c. In this way, the protrusions 23 abut against the left wall portion 11b, etc., so that the left and right positions of the support member 20 with respect to the cultivation bed 10 can be determined, and therefore, the gaps SK can be easily formed on the left and right outer sides of the extending portions 21.

[0039] The gas tube 30 shown in Figures 1 and 2 is for supplying gas to the plant S. The gas tube 30 is supported by the recess 22a of the support member 20, and is arranged so as to pass back and forth above the plant S. Note that in the cross-sectional views of Figure 2 and the like, for the sake of convenience of explanation, a gap is formed between the recess 22a and the gas tube 30, but in reality, the gas tube 30 is placed in the recess 22a.

[0040] One end of the gas tube 30 is connected to a carbon dioxide supply device installed in the facility. The gas tube 30 is also formed with a small hole with a diameter of several mm. The gas tube 30 can supply carbon dioxide gas G to the plant S through the hole. By supplying the carbon dioxide gas G to the plant S in this way, the photosynthesis of the plant S can be promoted. The gas supplied to the plant S is not limited to carbon dioxide gas G, and can be appropriately changed depending on the growth condition of the plant S, the season, etc. For example, the gas tube 30 can also supply air (conditioned air) whose temperature and humidity have been adjusted.

[0041] The vinyl sheet 40 is a flexible sheet-like member. The vinyl sheet 40 is provided so as to cover the support member 20 and the gas tube 30 from the outside. In this way, the vinyl sheet 40 can cover the surroundings of the plant S, and can provide, for example, insect control measures. For convenience of explanation, the vinyl sheet 40 is shown by a two-dot chain line in FIG. 1. The vinyl sheet 40 includes a left sheet 41 that covers the support member 20, etc. from the left side, and a right sheet 42 that covers the support member 20, etc. from the right side. The procedure for covering the support member 20, etc. with the left sheet 41 and the right sheet 42 will be described below.

[0042] 3 shows the left sheet 41 and the right sheet 42 before covering the support member 20, etc. The left sheet 41 shown in FIG. 3 is a roll-shaped vinyl sheet 40 that has been unwound and cut. The left sheet 41 has a front-to-rear width that is larger than the front-to-rear width of the cultivation bed 10.

[0043] As shown in Fig. 4, the left side sheet 41 is lifted up on the left side of the support member 20 so that the surface faces the left-right direction. The front part of the left side sheet 41 is folded rightward with the front support member 20 (extension 21) as a fulcrum. The rear part of the left side sheet 41 is folded rightward with the rear support member 20 (extension 21) as a fulcrum. The upper part of the left side sheet 41 is placed on the connection part 22 and the gas tube 30. In this way, the left side sheet 41 can cover the front side, rear side, left side and upper side of the support member 20 etc.

[0044] As described above, a gap SK is formed between the pair of extension parts 21 and each wall part (such as the left wall part 11b) of the cultivation bed 10. In this embodiment, the lower end part of the left sheet 41 is disposed in the gap SK (see FIG. 2). Thus, the lower end part of the left sheet 41 is disposed inside the cultivation bed 10.

[0045] The right sheet 42 shown in Fig. 3 is installed in the same manner as the left sheet 41, and can cover the front, rear, right and upper sides of the support member 20, etc. The upper part of the right sheet 42 is placed on the upper part of the left sheet 41 as shown in Fig. 2. The vinyl sheet 40 (the left sheet 41 and the right sheet 42) is flexible, so that it can be installed on cultivation beds 10 of different sizes.

[0046] The sheet covering the plant S is not limited to the vinyl sheet 40 as long as it is flexible. For example, it may be a vinyl film thinner than the vinyl sheet 40. The material constituting the sheet is not limited to vinyl, but is preferably a material that transmits light.

[0047] The clip 50 shown in FIG. 5 is for attaching the vinyl sheet 40 to the support member 20. The clip 50 has an openable and closable clip portion 50a and a knob 50b that an operator can grasp to open the clip portion 50a. The clip 50 can attach the vinyl sheet 40 to the support member 20 by sandwiching the support member 20 and the vinyl sheet 40 with the clip portion 50a. The clip 50 can also adjust the attachment position of the vinyl sheet 40 relative to the support member 20 by grasping the knob 50b to open the clip portion 50a. Note that in the drawings other than FIG. 5, the clip 50 is shown in a simplified form for the sake of convenience.

[0048] 2, the clip 50 includes a left clip 51 for attaching the left sheet 41, and a right clip 52 for attaching the right sheet 42. The left clip 51 attaches the upper and lower middle portions of the left sheet 41 to the left extension portion 21. The right clip 52 attaches the upper and lower middle portions of the right sheet 42 to the right extension portion 21. Thus, in this embodiment, the clip 50 attaches the vinyl sheet 40 to the support member 20 so that the upper and lower portions of the vinyl sheet 40 can be opened and closed.

[0049] According to the plant cultivation device 1, the vinyl sheet 40 can be opened and closed depending on the purpose. For example, as shown in Fig. 6, by opening the vinyl sheet 40 in summer, the warm air K inside the vinyl sheet 40 can be easily released to the outside, and the temperature rise inside the vinyl sheet 40 can be suppressed.

[0050] In the state shown in Fig. 6, the bottom of the vinyl sheet 40 is closed. Therefore, when carbon dioxide gas G is supplied from the gas tube 30, the vinyl sheet 40 prevents the carbon dioxide gas G, which is heavier than air, from leaking to the outside. In this way, the carbon dioxide gas G is retained within the vinyl sheet 40, and the plant S can be efficiently cultivated. Also, even when the nutrient solution Y or the like is cooled by localized cooling or the like, it is possible to prevent cold air from leaking out of the vinyl sheet 40. This improves the cooling efficiency and reduces air conditioning costs.

[0051] Furthermore, by closing the top of the vinyl sheet 40 in winter (see FIG. 2), when the nutrient solution Y is heated by local heating or the like, it is possible to prevent the warm air K from leaking out of the vinyl sheet 40. This increases the heating efficiency and reduces heating costs.

[0052] 7(a) and 7(b), the work can be performed efficiently by opening the top or bottom of the vinyl sheet 40 depending on the work. Also, by adjusting the position of the clips 50, the degree to which the vinyl sheet 40 is opened can be changed depending on the work, improving convenience.

[0053] In this way, the plant cultivation device 1 can open and close the vinyl sheet 40 according to the purpose, so that the plant S can be cultivated without replacing the vinyl sheet 40 with a different type of sheet. This can improve the workability.

[0054] In this embodiment, as shown in Fig. 2, the lower end of the vinyl sheet 40 is placed inside the cultivation bed 10, and carbon dioxide gas G is supplied into the vinyl sheet 40. This configuration makes it difficult for the carbon dioxide gas G to pass between each wall part (left wall part 11b, etc.) of the main body part 11 and the vinyl sheet 40, and the carbon dioxide gas G can be retained within the vinyl sheet 40. This allows the plants S to be cultivated efficiently. Also, for example, even if the ventilation equipment of the facility is moved, the vinyl sheet 40 can suppress leakage of the carbon dioxide gas G, and it is possible to ventilate the facility and promote photosynthesis by the carbon dioxide gas G.

[0055] As described above, the plant cultivation device 1 of this embodiment comprises a cultivation bed 10 for cultivating a plant S, a support member 20 for supporting a gas tube 30 for supplying gas (carbon dioxide gas G) to the plant S in the cultivation bed 10, a flexible vinyl sheet 40 (sheet) for covering the periphery of the plant S in the cultivation bed 10, and clips 50 (mounting members) for attaching the vinyl sheet 40 to the support member 20 so that the vinyl sheet 40 can be opened and closed.

[0056] By configuring it in this manner, the condition around the plant S can be changed by opening and closing the vinyl sheet 40 according to the purpose without removing the vinyl sheet 40, thereby improving workability.

[0057] Moreover, the clip 50 is configured so that the attachment position of the vinyl sheet 40 relative to the support member 20 is adjustable (see FIG. 7).

[0058] By configuring in this way, convenience can be improved.

[0059] In addition, the support member 20 is arranged on both sides of the plant S in the cultivation bed 10 and includes a pair of extension portions 21 extending vertically, and a connection portion 22 that connects the upper ends of the pair of extension portions 21 above the plant S in the cultivation bed 10, and the connection portion 22 is formed to be concave downward and has a recess 22a that supports the gas tube 30 (see Figure 2).

[0060] By configuring in this way, it is possible to stably support the gas tube 30 at a relatively high position (above the plant S).

[0061] The lower end of the vinyl sheet 40 is disposed inside the cultivation bed 10 (see FIG. 2).

[0062] With this configuration, water (e.g., condensation water, etc.) adhering to the inside of the vinyl sheet 40 can flow into the cultivation bed 10, and the outside of the cultivation bed 10 can be prevented from becoming dirty.

[0063] In addition, a portion of the support member 20 (the lower part of the extension portion 21) is positioned inside the cultivation bed 10, and a gap SK is formed between the portion of the support member 20 and the inner surface of the cultivation bed 10 (see Figure 2).

[0064] By configuring it in this manner, the lower end of the vinyl sheet 40 can be easily positioned inside the cultivation bed 10 by utilizing the gap SK.

[0065] The vinyl sheet 40 according to this embodiment is one embodiment of a sheet according to the present invention. Moreover, the clip 50 according to this embodiment is one embodiment of a mounting member according to the present invention.

[0066] Although the embodiment of the present invention has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

[0067] For example, the lower end of the vinyl sheet 40 does not necessarily need to be placed inside the cultivation bed 10, and can be placed outside the cultivation bed 10 depending on the type of plant S. For example, as shown in FIG. 8, when cultivating a plant S whose fruits droop, such as strawberries, the lower end of the vinyl sheet 40 can be placed outside the cultivation bed 10. Note that if the lower end of the vinyl sheet 40 is placed outside the cultivation bed 10, the effect of retaining carbon dioxide gas G within the vinyl sheet 40 may decrease. Therefore, it is also possible to provide a member that closes the gap between the vinyl sheet 40 and the outside of the cultivation bed 10 as much as possible while allowing the fruits of the plant S to droop.

[0068] As shown in FIG. 1, two support members 20 are provided for one cultivation bed 10, but the number of support members 20 can be changed appropriately depending on the size (front-rear width) of the cultivation bed 10, etc.

[0069] In addition, the support member 20 is abutted against the tray 12 to suppress the relative movement with respect to the cultivation bed 10, but the method for suppressing the relative movement is not limited to this embodiment. The support member 20 may be fixed to the main body 11, for example, to restrict the relative movement.

[0070] Also, although the vinyl sheet 40 is described as being opened and closed manually, it can be configured to be opened and closed automatically. For example, by using a variable material (such as a shape memory alloy) that changes shape depending on the temperature, it is possible to open the top of the vinyl sheet 40 at high temperatures and close the top of the vinyl sheet 40 at low temperatures. This can eliminate the trouble of opening and closing the vinyl sheet 40, further improving workability.

[0071] In this embodiment, the gas tube 30 is placed on the support member 20 (see FIG. 2), but it is also possible to suspend the gas tube 30 from the support member 20 via a wire W or the like (see FIG. 9). When suspending the gas tube 30, the height of the gas tube 30 may be changed depending on the measurement position of the carbon dioxide sensor installed in the facility and the type of plant S.

[0072] Furthermore, the shape of the support member 20 is not limited to this embodiment, and can be changed as desired. For example, the connection portion 22 may be formed in a shape that is convex upward. FIG. 10 shows, as an example, a connection portion 22 that is formed in an upwardly convex arc shape when viewed from the front. When the vinyl sheet 40 is placed (supported) on the connection portion 22, the upper portion of the vinyl sheet 40 can be formed to bulge upward. Note that the connection portion 22 need not be arc-shaped when viewed from the front, but may be substantially inverted V-shaped when viewed from the front (like a gable roof), or the like.

[0073] As described above, the connection portion 22 is formed so as to be convex upward, and the upper portion of the vinyl sheet 40 is supported by the connection portion 22 and is formed so as to cover the upper part of the plant S in the cultivation bed 10.

[0074] With this configuration, water adhering to the upper part of the vinyl sheet 40 can be guided downward.

[0075] Furthermore, the configuration of the clip 50 is not limited to this embodiment (see FIG. 5). For example, the clip 50 may be formed in a packer shape (having a substantially C-shaped cross section) that can fit into the support member 20. Furthermore, the vinyl sheet 40 does not necessarily have to be attached by the clip 50, and may be attached to the support member 20 by a member other than the clip 50.

[0076] In addition, in this embodiment, an example in which one cultivation bed 10 is covered with a vinyl sheet 40 has been shown, but as shown in FIG. 11(a), it is also possible to cover multiple cultivation beds 10 arranged in a horizontal direction (front-rear direction in FIG. 11(a)) with a common vinyl sheet 40. In FIG. 11(a), for the sake of convenience, the vinyl sheet 40 is shown by a two-dot chain line. When multiple cultivation beds 10 are covered with a common vinyl sheet 40, the plant cultivation device 1 may be provided with a connecting member 60 that connects the multiple cultivation beds 10.

[0077] As shown in FIG. 11(b), the connecting member 60 includes a flat plate portion 61 and legs 62. The flat plate portion 61 is disposed with its plate surface facing the up-down direction. The flat plate portion 61 has a width approximately equal to the left-right width of the cultivation bed 10 (more specifically, the width from the inner surface of the left wall portion 11b to the inner surface of the right wall portion 11c). The legs 62 are formed so as to extend downward from the flat plate portion 61. The legs 62 are formed at each of the four corners of the flat plate portion 61 (the left front end, the right front end, the left rear end, and the right rear end).

[0078] 11(a), the flat plate portion 61 is placed on the front cultivation bed 10 (rear wall portion 11e) and the rear cultivation bed 10 (front wall portion 11d). The legs 62 are hooked on each cultivation bed 10 (front wall portion 11d and rear wall portion 11e) to be engaged with the cultivation bed 10.

[0079] The vinyl sheet 40 used is larger than that of this embodiment (longer than the distance from the rear end of the rear cultivation bed 10 to the front end of the front cultivation bed 10) and is installed across the two cultivation beds 10 using the same procedure as in this embodiment (see FIG. 4). The vinyl sheet 40 is attached to not only the support member 20 but also the connecting member 60 with clips 50.

[0080] As shown in an example in FIG. 11(a), by connecting the cultivation beds 10 with the connecting member 60, the gap between the cultivation beds 10 (the gap between the rear wall portion 11e of the front cultivation bed 10 and the front wall portion 11d of the rear cultivation bed 10) which is difficult to close with a common vinyl sheet 40 can be closed from above with the flat plate portion 61. With this configuration, it is possible to prevent the carbon dioxide gas G in the vinyl sheet 40 from flowing downward through the gap. Note that the method of engaging the cultivation beds 10 and the connecting member 60 is not limited to the leg portion 62, and can be changed as desired.

[0081] As described above, a plurality of the cultivation beds 10 are arranged along the horizontal direction, and the plant cultivation device 1 further includes connecting members 60 (closing members) that close gaps between the cultivation beds 10 adjacent to each other.

[0082] By configuring in this manner, even if the vinyl sheets 40 are placed together on adjacent cultivation beds 10, the escape of carbon dioxide gas G can be suppressed, so that the cultivation of the plants S and the installation of the vinyl sheets 40 can be carried out efficiently.

[0083] The connecting member 60 is provided with a plurality of legs 62 (engagement portions) that can be engaged with the adjacent cultivation beds 10, respectively.

[0084] With this configuration, multiple cultivation beds 10 can be easily connected together.

[0085] The connecting member 60 according to this embodiment is one embodiment of a blocking member according to the present invention. Moreover, the leg portion 62 according to this embodiment is one embodiment of an engagement portion according to the present invention. [Explanation of symbols]
