Description

[Detailed explanation of the idea] The present invention relates to a plant water culture device.

Due to the difficulty in obtaining land for plant cultivation in subcommittees and the like, and furthermore, the soil for plant cultivation has become expensive and difficult to obtain, many proposals have been made for plant cultivation.

The present applicant has also proposed a plant hydroculture device that enables cultivation from seeds and allows plants to always contact and absorb water well without being affected by the increase or decrease of water contained in the container.

However, in the conventional multiplier, a hollow frame body made of synthetic resin and having a semi-circular arc cross section is brought into close contact with each other, and a perforated plate is sandwiched between them to obtain a sealed hollow frame body. It was extremely difficult to manufacture, prone to defective products, and difficult to inspect.

The present invention is an attempt to solve the above-mentioned drawbacks of conventional products, and since it does not require complete sealing of the hollow frame, the frame is made of a ring-shaped body made of a material with strong buoyancy, such as urethane foam or polystyrene foam. By incorporating it into
To provide a plant water cultivation device which is easy to manufacture and has high buoyancy.

The details of the present invention will be explained with reference to embodiments shown in the figures.

In FIG. 1, a hydroponic device 3 is placed in a container 2 containing water 1, that is, plant cultivation water mixed with chemical fertilizers and the like.

The hydroponic device 3 includes a perforated plate 4 and an upper frame 5 as shown in FIG.
and a lower frame body 6.

The perforated plate 4 is made of a commonly used plate such as a net-like body such as a plastic or metal net, a plastic plate, cloth, a thin metal plate, etc., in which a large number of small holes of arbitrary shapes are formed.

The frames 5 and 6 are each made of a ring body made of synthetic resin and having a semicircular arc shape in cross section, and can also be formed from a pipe material such as a vinyl pipe cut in half.

The frame body 5°6 is most simply a ring-shaped structure as shown in Fig. 3.
Further, it is processed to form a polygonal frame or the like as necessary.

In Fig. 2, T is a ring body made of a foamed resin made of a highly buoyant material such as foamed urethane, foamed polystyrene, etc. This ring body I is formed when the opening surfaces of the frame body 5.6 are joined together. It is preferable that the shape and size be selected to fit the hollow part.

The inner peripheral sides of the frames 5 and 6, that is, the portions that clamp the perforated plate 4, may have grooves 5a and 6a that fit into each other, as shown in FIG.

The perforated plate 4 is held taut at its peripheral edge by frames 5 and 6.

When this happens, the ring body I is fitted into the recess of the frame body 6, and the grooves 5a and 6a of the frames 5 and 6 fit into each other to sandwich the perforated plate 4, thereby preventing the perforated plate 4 from falling off. do.

The frames 5 and 6 are tightly fitted together and formed as if they were one member with a built-in ring body together with the perforated plate 4.

The hydroponic device 3 formed as shown in FIG. 2 or 3 can float on water.

The effect as a floating body is obtained because the frames 5 and 6 form hollow pipe bodies, and furthermore, they have a ring body I made of foamed resin built into the ring-shaped hollow frame.

When seeds are scattered on a perforated plate 4 with a hydroculture device 3 floating on water 1, the seeds absorb water well and grow without being submerged or separated from the water.

Since the seeds are not submerged in water, there is no possibility of oxygen deficiency.

Even if the water 1 decreases due to evaporation or increases due to water supply, the hydroponic device 3 always floats on the surface of the water 1, so that good contact with the water can always be obtained.

Since seeds always have a surface in contact with water and a surface in contact with air, stable moisture collection and air respiration can be obtained.

Not only seeds (even plants that already have roots and branches can be cultivated by simply placing them on the perforated plate 4).

Since the hydroponic device 3 floats on the water surface, it moves up and down according to changes in the water level, so it is possible to replenish water without having to replenish water until the water level is almost zero, and it can be used frequently. There is no need to supply water into the container, and it is sufficient to maintain the water in the container 1 so that it does not run out.

The frames 5 and 6 can be formed not only as shown in FIG. 2 but also as shown in FIG.

The frame body 50 has a deep concave portion and a protruding frame portion 50a50b.
has.

The peripheral edge of the perforated plate 4 is bent and aligned with the inner surface of the inner frame portion 50b of the frame body 50, and an elastic fixing ring TO made of foamed resin is fitted into the frame body 50.

Therefore, according to this embodiment, the bent peripheral edge of the perforated plate 4 is compressed and held within the frame 50, and only one frame 50 is required.

As mentioned above, this invention has a highly buoyant foamed resin built into the frame, so even if water gets into the frame when it is suspended in water for plant cultivation, the buoyancy will not be impaired.
Furthermore, since there is no need to be particular about sealing the frames when joining them together, the workability in production is extremely good.
