[0005]

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a building structure forming a cultivation room, and a large number of hanging members 2 are arranged in the building structure 1 in parallel. On each of the hanging members 2, a number of nutrient cultivation beds 3 arranged in a direction orthogonal to the hanging members 2 are suspended in parallel by a suspension mechanism 5 and suspended in a cultivation room. . Further, the nutrient cultivation bed 3 is adjustable in height and movable. Reference numeral 4 denotes a nutrient solution supply mechanism attached to the nutrient solution cultivation bed 3, and the nutrient solution supply mechanism 4 is also suspended above the hollow of the cultivation room by a suspension mechanism 5. In addition, the above-mentioned building structure 1
As shown in FIG. 4, there are a type in which a truss as the hanging member 2 is stretched, and a type in which a horizontal pipe is stretched as shown in FIG.

The hydroponic culture bed 3 has a long gutter-like body 6 and a ridge 6a formed at the center of the gutter-like body 6.
And a rock wool bed 7 placed on the bed. Drainage grooves 8a as drainage mechanisms 8 are formed on both sides of the gutter-shaped body 6 so that excess nutrient solution flowing out of the rock wool bed 7 can be discharged to the outside. The long gutter-like body 6 is provided with a slope in order to discharge excess nutrient solution without stagnation. The rock wool bed 7 includes a rock wool base 7a and a rock wool block 7b, and seeds of cultivated plants are planted on the rock wool block 7b.
Instead of the rock wool base 7a, the rock wool bed 7 may be made of bagged coco peat.

Further, the nutrient solution supply mechanism 4 includes a liquid supply pipe 4a disposed on the lower surface of a ridge 6a formed at the center of the gutter-like body 6, and a branch pipe branched from the liquid supply pipe 4a. 4b, the tip of the branch pipe 4b connected to the liquid supply pipe 4a is located at each of the rock wool blocks 7b so that the nutrient solution can be supplied to the rock wool block 7b.

The suspending mechanism 5 allows the height of suspending the nutrient cultivation bed 3 to be adjustable by a chain 9 and a turnbuckle 10, and an S-shaped hook 11 hooked to the suspending member 2. It is made movable by sliding and changing the hook position. By changing the locking position of the chain 9 locked to the S-shaped hook 11 or the hook of the turnbuckle 10, the suspension length can be freely changed using one link of the chain 9 as a minimum unit. . The turnbuckle 10 can adjust the length of one link or less. In addition, the S-shaped hook 11 forms a rectangular upper hook 11a that matches the square shape of the hanging member 2 so that it does not move in the direction orthogonal to the axial direction of the hanging member 2, so that the nutrient solution is cultivated. The roll of the bed 3 is easily converged. Reference numeral 12 denotes a hanging bracket for hanging the gutter 6.

[0009] The thus constructed first is a nutrient solution cultivation via each hanging mechanism 5 hooked on a number of hanging members 2 arranged side by side in a building structure 1 forming a growing room. Bed 3 is suspended in the cultivation room. For this suspension, the suspension 3 may be hooked on the hanging member 2 or the hanging mechanism 5 may be hooked on the hanging member 2 in advance, after being hooked on the nutrient cultivation bed 3 with a large number of hanging fittings 12. The nutrient solution cultivation bed 3 may be locked to the hanging metal fitting 12 of the hanging mechanism 5 that is hung. Next, the height of each suspension mechanism 5 is adjusted. This adjusts the length of the chain 9 locked to the S-shaped hook 11 to set a rough suspension height. Subsequently, fine adjustment is performed by the turnbuckle 10 locked to the chain 9 so that the suspended nutrient solution cultivation bed 3 has a constant gradient from the start end to the end. 7, so that the drainage can flow out of the drainage groove 7a. At this time, the height of the nutrient cultivation bed 3 is set to a height at which the worker can easily work.

[0010] In this manner, if a number of the nutrient cultivation beds 3 in a row are suspended in parallel with the plurality of hanging members 2 and the nutrient solution flows from the liquid supply pipe 4 a of the nutrient solution supply mechanism 4, The nutrient solution is supplied from the supply pipe 4a to the rock wool block 7b via the branch pipe 4b. Then, the nutrient solution wets the rock wool block 7b on which the cultivated plant is planted and permeates the rock wool bed 7. The surplus nutrient solution that moistened the rock wool bed 7 is collected in the left and right drain grooves 8a of the drain mechanism 8 formed in the gutter-like body 6, and is discharged according to the gradient.

As described above, since the nutrient cultivation bed 3 is suspended and there are no obstacles on the floor of the cultivation room, the worker can freely move the floor to care for the cultivated plants. Therefore, work can be performed efficiently. Moreover, the hydroponic bed 3 is suspended and has good air permeability,
Suppresses the occurrence of various bacteria and does not cause disease. Further, since the height of the hydroponic culture bed 3 is adjusted to the height of the worker, the physical burden during the work can be reduced. Moreover, when the cultivated plants grow and become difficult to maintain, the height of the hydroponic cultivation bed 3 can be lowered to improve workability,
It is possible to prevent the cultivated plants from interfering with each other or to reduce the amount of sunlight by increasing the interval between the rows of the nutrient cultivation beds 3 arranged in parallel, and to grow the plants efficiently.

FIGS. 6 and 7 show another example of the nutrient solution cultivation bed 3 and the hanging fitting 12 of the hanging mechanism 5. As shown in the preferred embodiment, the nutrient solution cultivation bed 3 is not shown. Instead of the gutter 6 and the rock wool bed 7, the container 13 is a container bed filled with rock wool fine granules or coco peat, and the hooks 13 a formed on both sides of the container 13 are provided as hanging fittings of the hanging mechanism 5. The hook is hung on two parallel support pipes 14 provided in the apparatus 12 and suspended. The suspension fitting 12 is provided with a liquid supply pipe 4a of the nutrient solution supply mechanism 4 and a drainage pipe 8b as a drainage mechanism 8. The drainage pipe 8b and the bottom of the container 13 are connected by a short pipe so that excess nutrient solution flowing out of the container bed is discharged to the drainage pipe 8b. A spacing member is provided between the support pipes 14 as needed. The spacing member is formed in a gap between the containers 13 arranged in series.

FIG. 8 shows still another example of the nutrient cultivation bed 3 and the hanging metal fitting 12 of the hanging mechanism 5. The gutter-like body 6 having a substantially U-shaped cross section is shown. Waterproof sheet 1
5 and the nutrient solution is allowed to flow directly into the gutter 6 instead of the rock wool bed 7 or the container bed filled with rock wool fine granules or coco peat. A rock wool block 7b in which the cultivated plants are planted is attached to a styrofoam lid plate in which the cultivated plants are arranged so as to close the upper opening of the gutter 6 so that the cultivated plants can be contacted.

In the preferred embodiment, the chain 9 and the turnbuckle 10 are used to adjust the height of the nutrient solution cultivation bed 3. However, the chain is wound up by an electric motor, or a rack and pinion type height adjustment is performed. Of course, a mechanism may be incorporated.

In addition, the height of the hydroponic culture bed can be adjusted while the worker is standing, so that the physical burden can be reduced. Furthermore, since it is suspended, the air permeability under the hydroponic culture bed is good, and it is possible to prevent the occurrence of diseases and various germs. Further, the lower part of the hydroponic bed can be used as a seedling raising space. As described in the second aspect, the height and the horizontal accuracy of the nutrient cultivation bed can be easily set by making the height adjustable and movable. Further, since the height can be set according to the height of the worker, the workability can be improved, and the physical burden can be reduced. Moreover, by adjusting the height in accordance with the growth of the cultivated plant, the workability can always be optimized. Furthermore, by making the hydroponic bed movable, it is possible to provide an optimum cultivation area according to the size of the cultivated plant and to always maintain an interval corresponding to the growth of the cultivated plant. It does not cause a decrease in sunlight. By providing a drainage mechanism for discharging excess nutrient solution to the outside as in claim 3, the nutrient solution can be circulated and used, and deterioration and decay of the nutrient solution can be suppressed. Claim 4
As described above, the height of the nutrient cultivation bed is adjusted by the chain and the turnbuckle of the suspension mechanism, so that the height can be adjusted with high accuracy while the structure is simple and inexpensive. . By moving the bed for nutrient cultivation using the S-shaped hook of the suspension mechanism, the bed for nutrient cultivation can be moved at very low cost. Since the bed for nutrient cultivation is hooked to the left and right support pipes of the suspension mechanism with hooks as in claim 6, the bed for nutrient cultivation can be easily attached and detached, thereby improving workability. In addition to being able to improve, it has various advantages such as easy cultivation of cultivated plants having different cultivation periods. Therefore, the present invention greatly contributes to the development of the industry as a cultivation apparatus that solves the conventional problems.
