Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a floating body for hydroponic cultivation.

[Conventional technology] Conventionally, this type of floating body for hydroponic cultivation was
Various things have been proposed. For example, there is a floating body such as that used in the method of cultivating plants disclosed in Japanese Patent Application No. 60-232826 previously filed by the applicant of the present application. This floats on the liquid in the tank, and plants can be placed on top of it. A lid is removably attached to the upper opening of the liquid storage tank, and an insertion hole is opened in the lid to allow the plants to pass through, allowing the plants to come out above the lid and direct sunlight to the roots of the plants. The structure is designed to prevent the roots from drying out by preventing them from being irradiated.

[Problems to be solved by the invention] However, with the above-mentioned configuration, when the plants move up and down together with the floating body due to a decrease or increase in liquid, the plants come into contact with the edge of the insertion hole in the lid, causing damage to the plants. There were drawbacks such as damage to the tank and difficulty in determining the amount of liquid in the storage tank.

[Means for Solving the Problem] Therefore, the present invention provides a floating substrate 5 on which a water-absorbent fabric 10 is placed, which is suspended in a liquid 2 and a part of which is immersed in the liquid 2. By attaching the cover plate 6 having the hole 6a through the cover plate support 7, the above-mentioned difficulty can be solved.

[Function] Accordingly, the lid plate 6 moves up and down together with the floating substrate 5 and the plants S placed thereon as the liquid 2 increases and decreases, and the direct irradiation of sunlight etc. to the roots of the plants S is prevented by the lid. It is blocked by the board 6, and the roots of the plants S are prevented from drying out.

[Example] The present invention will be described below with reference to the drawings.

In the figure, A indicates a floating body for hydroponic cultivation on which plants S are placed and suspended in a liquid 2 such as water or liquid fertilizer stored in a liquid storage tank 1. A floating body 5 that is capable of floating and on which a plant S can be placed, a lid plate 6 in which a plant insertion hole 6a is bored, and a lid plate 6 that is placed above the floating substrate 5 (to the plant S to be placed). (its height is determined accordingly)
The floating substrate 5 is made up of a cover plate support 7 that is supported by a lid plate support 7, and a water-absorbing fabric 10, one end of which is immersed in the liquid 2 and placed on the upper surface of the floating substrate 5.

The liquid storage tank 1 may be of any type as long as it can store the liquid 2 and accommodate the floating bodies A, and its size, material, shape, etc. can be freely set as appropriate. The liquid storage tank 1 used for household use is formed small (for example, by using a planter, etc.), and the liquid storage tank 1 used for commercial use is formed large (for example, by using a waterway of an appropriate width for circulation). etc.).

The floating substrate 5 is made of a material with relatively high buoyancy, such as a styrofoam plate, for example. By the way, the floating substrate 5 should be formed in such a size and shape that the plants S can be stably placed thereon, and that its upper surface is located above the liquid level of the liquid 2 when the plants S are placed thereon. Good. Note that the floating substrate 5 is configured so that capillary phenomenon occurs on itself, and even without using the water-absorbing fabric 10, the liquid 2 can be applied to the upper surface of the floating substrate 5.
It may be configured such that it can suck up and hold the water. In addition, the floating substrate 5 is
As shown in FIG. 6, a plurality of support columns 9 may be appropriately installed vertically on the lower surface thereof. That is, this support 9 is
By bringing the lower end into contact with the bottom wall of the liquid storage tank 1, the entire floating body A can be stabilized.
It can be freely set as appropriate depending on the floating body A, etc. Moreover, the floating body A equipped with the pillars 9 as described above brings the lower ends of the pillars 9 into contact with the bottom wall of the liquid storage tank 1 by adjusting the total amount of liquid 2 in the liquid storage tank 1 (adjusting the water level). At least the floating body A can be stabilized, or the lower end of the support column 9 can be made to float above the bottom wall of the liquid storage tank 1 by raising the water level, and the floating body A can be moved. Incidentally, instead of the above-mentioned support 9, a protrusion of an appropriately configured structure may be provided protruding from the bottom wall of the liquid storage tank 1, or a support of an appropriately configured structure may be mounted on the bottom wall of the liquid storage tank 1. It's okay to leave it there.

Like the floating substrate 5, the cover plate 6 is thinly formed of a lightweight material such as a styrofoam board, and has plant insertion holes 6a of a size corresponding to the plants S to be installed at appropriate positions on the cover plate 6. Several holes have been drilled.

The cover plate support 7 is constructed by appropriately bending a wire into a substantially square U shape (see Fig. 1), and the tip of the cover plate support 7 is inserted into the mounting hole 5a of the floating board 5 from below. The cover plate 6 is formed so that it can be attached arbitrarily above the floating board 5 by inserting the cover plate 6 through the floating board 5 and inserting the mounting hole 6b through the distal end portion of the cover plate support 7. In addition, after the lid plate 6 is attached, the lid plate support 7 is bent at its tip and the lid plate 6 is attached.
prevents it from coming off upwards.

In the figure, reference numeral 8 denotes a stopper that is detachably attached to the cover plate support 7. As shown in the illustrated example, this stopper 8 prevents the cover plate 6 from moving downward, and also moves the cover plate 6 to the cover plate support. It is used so that it can be attached at an appropriate position. The stopper 8 may also be attached to the upper surface of the floating substrate 5 of the lid plate support 7 to securely fix the lid plate support 7 to the floating substrate 5 (not shown). By the way, in the illustrated example, this stopper 8 is constructed by screwing a set screw onto a substantially U-shaped base piece, and the end of the set screw holds the cover plate support 7 held by the base piece. It is formed so that it can be fixed to the support body 7 by pressing. However, the structure of the stopper 8 is not limited to this, and other suitable means can be adopted. Also,
The number and arrangement positions of the stoppers 8 can also be freely set as appropriate.

The cover plate support 7 may be made of a foamed polystyrene plate, which is glued so as to be interposed between both end portions (or the entire peripheral portion may be sufficient) of the floating substrate 5 and the cover plate 6 (see Fig. 4). ), and others can be set freely as appropriate.

The water-absorbent fabric 10 may be constructed by, for example, superimposing a cloth-like material 10a with good water-absorbency and a felt-like material 10b with good water-retention property so that the liquid 2 can be sucked up and retained smoothly. It is possible to use only the cloth-like material 10a (see FIG. 1), or to use other appropriate water-absorbing fabrics. Further, the water-absorbing fabric 10 may be disposed so as to cover almost the upper surface of the floating substrate 5 (see FIG. 5), or only in the lower part of the plant insertion hole 6a where the plant S is placed. (see FIG. 2), or can be freely set as appropriate. Furthermore, the amount of liquid 2 sucked up and the amount of water retained on the upper surface of floating substrate 5 can be adjusted by adjusting the amount of water-absorbent fabric 10. Note that the water absorbent fabric 10 may be attached to the floating substrate 5 in advance so as not to shift on the floating substrate 5.

By the way, the floating body A may be configured such that the floating substrate 5, the cover plate 6, and the cover plate support 7 are separate bodies as described above for convenience in assembly, storage, transportation, etc., or the floating body A may be configured as a separate body as described above. Although omitted, it may be configured integrally.

The floating body A of the present invention is constructed as described above, and its use will now be explained. First, a liquid 2 such as water or liquid fertilizer is put into a liquid storage tank 1, and the floating body A is suspended in this liquid 2. At this time, both ends of the water-absorbing fabric 10 placed on the top surface of the floating substrate 5 of the floating body A are immersed in the liquid 2 for an appropriate length, and the liquid 2 is sucked up to the top surface of the floating substrate 5 using capillary action. and retained.

Next, the plants S, such as seedlings and seedlings, which have been taken out of their pots and have leaf mold S1 still attached to their roots, are
It is placed on the water absorbent fabric 10 on the upper surface of the floating substrate 5. At this time, as shown in FIG. 2, the upper part of the humus S1 may be installed so as to close the plant insertion hole 6a of the cover plate 6. In addition, if the plant S falls down, a support rod may be provided upright on the cover plate 6. Also, Mitsuha,
Salad vegetables and the like can be cultivated by disposing a sponge or the like on the floating substrate 5 so as to close the plant insertion hole 6a and sowing seeds thereon.

By the way, when the lid plate 6 can be moved up and down by the lid plate support 7, by moving the lid plate 6 up and down, it is possible to easily place and take out the plants S. There is.

The floating body A is floated in a liquid storage tank 1 equipped with a water channel for appropriate circulation, and by giving a flow in a certain direction to the liquid 2 in this liquid storage tank 1, the floating body A is circulated while floating. It is also possible to allow an operator to observe the growing state of the plants S of the floating bodies A flowing in a certain place, or to harvest and plant the plants S. In this way, it is possible to save labor in management work, reduce work effort, etc., and make effective use of the cultivation area.

The floating body A can be made to float in a liquid storage tank 1 equipped with a circular circulating waterway, for example, in a park or a restaurant, and by giving a flow to the liquid 2 in this liquid storage tank 1, the floating body A can be Plant S placed on A
It can also be used to improve the aesthetic appearance by moving the parts.

[Effect of the invention] Therefore, the present invention provides a floating body for hydroponic cultivation in which the plant S is suspended in a liquid 2 such as water or liquid fertilizer in a liquid storage tank 1 and a plant S is placed on it. The floating substrate 5 is made to float in the liquid 2 and the plants S are placed thereon, the lid plate 6 has a hole 6a for inserting the plant, and the lid plate 6 is connected to the floating substrate 5. Since the water-absorbent fabric 10, a part of which is immersed in the liquid 2, is disposed on the upper surface of the floating substrate 5, the floating substrate 5 can be supported by the lid plate 6. Plant S placed on top of 5
It is possible to prevent the roots of the plant S from being directly irradiated with sunlight, etc., and prevent the roots of the plant S from drying out. Moreover, since the lid plate 6 and the floating substrate 5 are connected via the lid plate support 7, the state of decrease in the liquid 2 can be easily determined from the height of the lid plate 6, and the liquid 2 When the floating substrate 5 moves up and down due to fluctuations in water level due to increases and decreases in 6a will not be damaged by the edge of the hole. In addition, the floating body A itself is in the liquid storage tank 1.
You will be able to float freely inside. Furthermore, the water-absorbing fabric 10 allows the liquid 2 to be sucked up to the upper surface of the floating substrate 5, thereby automatically supplying the liquid 2 to the plants S.

In addition, by forming the lid plate 6 so that it can be moved up and down by the lid plate support 7, placing and taking out the plants S can be easily performed by moving the lid plate 6 up and down. At the same time, the height of the plant S can be easily adjusted according to its size. Moreover, by providing the stopper 8,
The downward movement of the cover plate 6 can be reliably prevented, and the attachment state of the cover plate 6 to the cover plate support 7 and the attachment state of the cover plate support 7 to the floating board 5 can be stabilized. You will be able to plan even more.
