 The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a view of the cultivation container of the present invention seen from above, FIG. 2 is a side view thereof, and FIG. 3 is a sectional view taken along the line AA of FIG.

The circumference of the central container 1 is divided into four or more equal parts, and in the case of FIG. 1, every other one of the six parts is divided into three fan-shaped peripheral containers 2 without a partition wall between them. An upright shape that is connected and has a frusto-conical shape in the center of the central container 1 with open upper and lower ends and a small hole or a vertical slit 31 in the lower part of the side surface and is lower than the outer wall of the peripheral container. A number that is a truncated cone shape in which the tube 3 is fixed, has an inner diameter that is higher than the upright tube 3 and is larger than the outer diameter of the upright tube, and whose upper and lower ends are open and that has a lower portion corresponding to the number of peripheral containers. That is, the running water guide cap 4 radially provided with three downwardly-opening water collecting grooves 41 is superposed on the upright cylinder 3 in a state where the water collecting grooves reach the peripheral portion of the bottom of the surrounding container. Have been installed.

FIG. 4 is an enlarged view of the running water guide cap 4, which is a frustoconical shape with open upper and lower ends, and a downward-opening water collecting groove 41 corresponding to the number of peripheral containers having an ear or fan shape at the bottom. Are provided radially.

FIG. 5 is a diagram (cross-sectional view) for explaining the action of the flowing water guide cap 4, showing a state in which the medium 5 is filled in the central container 1 and the peripheral container 2.

Irrigation is intensively performed, for example, once a day. Water irrigated from above (indicated by an arrow) flows down the outer wall of the running water guide cap 4 and penetrates into the medium 5. The surplus water reaches the peripheral portion of the bottom of the peripheral container, and the space between the bottom of the peripheral container and the water collecting groove 41 from the end of the downwardly opened water collecting groove 41 radially provided in the running water guide cap 4. To reach the outer wall of the upright cylinder 3. A part of this water drops downward through a small hole or a vertical slit 31 provided in the lower part of the side surface of the upright cylinder 3.

Since the small holes are small and the vertical slits are thin,
The water that cannot be drained from here becomes excess water, rises between the outer wall of the upright tube 3 and the inner wall of the running water guide cap 4, and falls downward from the opening at the upper end of the upright tube 3.
Therefore, the medium 5 in the peripheral container 2 is always in a submerged state. However, when the irrigation is stopped, the water gradually drops downward through a small hole or vertical slit 31 provided at the lower part of the side surface of the upright cylinder 3, and the water level soon settles at the position of the lower end of the small hole or vertical slit 31.

Since the outer wall of the cultivation container 2 is higher than the upper opening of the upright tube 3, if the diameter of the upright tube 3 is made sufficiently wide, the water in the cultivation container will fall from the upright tube without overflowing to the outside in any case. Then, the next stage is moistened, and the same procedure is repeated to return to the water tank provided under the bottommost cultivation container.

In this way, the wet state of the medium 5 is maintained constant due to the combined effect of the upright cylinder 3 and the running water guide cap 4. In particular, old water will not stagnate in the circumferential portion that is farther away due to the center of the container.

Further, by setting the flowing water guide cap 4, the small holes or the vertical slits 31 provided in the upright cylinder 3 are not blocked by the artificial water moss for culture medium or plant roots.

Further, in the cultivation container having such a shape, as shown in the figure, if both the central container and the peripheral container have a shape in which the diameter of the lower part is small and the diameter of the upper part is large, a large number of empty cultivation containers can be stacked in a state of being fitted to each other. This has the advantage that it does not take up much space during transportation or storage.

The cultivation device of the present invention has a plurality of such cultivation containers,
The ear-shaped or fan-shaped peripheral container portions of the cultivation containers directly below or above each are stacked in such a positional relationship that they do not overlap each other, and a mechanism for watering the uppermost cultivation container is provided.

In the case of the cultivation container shown in FIG. 1 in which three peripheral containers 2 are connected at every other place where the circumference of the central container is equally divided into six, in the case of the upper and lower cultivation containers, By shifting the installation phase by 60 degrees, it is possible to stack the peripheral container parts of the cultivation containers directly below or above each other so that they do not overlap each other.

In this way, by stacking the peripheral container parts of the cultivation containers that are directly below or above it so that they do not overlap, a space with a height corresponding to the height of the peripheral containers is created above each peripheral container. The plants can grow in.

As shown in FIGS. 1 to 3, a notch 11 is provided in the upper peripheral portion of the central container 1 so that the bottom of the peripheral container having an ear shape or a fan shape can be fitted into the notch 11. Not only is the positioning easier when stacking, but the stability of the stack is increased.

FIG. 6 is a sectional view showing a cultivation apparatus in which the cultivation containers shown in FIGS. 1 to 3 are stacked in three stages, and the cultivation containers in three stages are installed on the water tank 6.

A irrigation pump 7 is provided below the water tank 6, and the water in the water tank 6 is irrigated by the irrigation pump 7 onto the uppermost cultivation container via the conduit 71. The conduit 71 is made of a flexible material such as a rubber tube or a vinyl tube, and if it is guided to the uppermost stage through the inside of the upright tube 3 of each cultivation container, it cannot be seen from the outside, so it is aesthetically pleasing. Above all preferred.

In the cultivation device illustrated in FIG. 6, an air blower 8 and an air filter 81 are further attached to the water tank 6. External air is sucked in through the small holes 82 and the air filter
The air is blown through the air blower 8 through the air blower 8, and the purified air is discharged under the upright tube 3 of the lowermost cultivation container through the air purification conduit 83.

Purified air supplied to the lower part of the upright tube 3 of the bottommost cultivation container rises inside the stacked upright tubes,
The air is released in the space between the upright cylinders and diffuses on the surface of the medium 5 filled in the peripheral container 2 of each stage, so that the plant stimulates the leaves by the flow of air, and the air is always purified. Because it grows in the atmosphere of, the growth will be vigorous.

Since this air passes through the plant layer and is released to the outside,
This cultivation device acts as a green filter.

Also, the water that falls from the upright cylinder part takes in oxygen by touching the air, so the water accumulated in each stage and the water in the tank will contain a large amount of dissolved oxygen, which is good for root development and Grows vigorously.

As the air filter 81, an appropriate one is used according to the environment in which this cultivation device is installed.

Generally, a filter material capable of removing fine particles such as cigarette smoke is used, but an adsorbent such as nitrogen oxide or sulfur oxide may be used together if necessary.

When filling the culture container with medium, do not use the soil,
It is preferable to use an inorganic artificial medium such as gravel or artificial water moss from the viewpoint of preventing damage due to soil fungi and the like.

If the irrigation pump 7 is used to irrigate the uppermost cultivating container of the cultivating apparatus assembled in this manner, the combination effect of the upright cylinder 3 and the running water guide cap 4 described above will cause The wet state of the medium 5 is maintained constant.

Then, the water overflowing the opening at the upper end of the upright tube of the uppermost cultivation container descends along the inner wall of the upright tube,
It falls on the outer wall of the running water guide cap 4 of the lower cultivation container. By repeating the same operation, the medium in the lowermost cultivation container is wetted in exactly the same state as the medium in the uppermost cultivation container.

The irrigation pump 7 may be operated by circulating the water once or several times a day using a time switch or the like depending on the type of plant and the temperature condition.

Fertilizers and medicinal components are added to the water in the aquarium depending on the type of plant and its state. Measure the pH and dissolved component concentration, and exchange with fresh water as needed.

The purified air may be supplied intermittently, but it is preferable to supply it continuously.

FIG. 6 shows an example of the cultivation apparatus of the present invention, and the number of stages can be increased and accessories can be added if desired.

FIG. 7 is a side view of an example thereof, and FIG. 8 is a view seen from above. Five cultivation containers are stacked, and a frame 9 is provided on the uppermost cultivation container. This frame 9
Is a vertical bar 91 standing on the outer wall upper edge of the ear-shaped or fan-shaped peripheral container in the uppermost cultivation container, or on the outer wall upper edge of the ear-shaped or fan-shaped peripheral container in the lower cultivation container. It can also be assembled by using the vertical rods 92 that have been stood up and joining the circular rods 93 to them.

Such a frame is convenient for growing vine plants.

The same type of plant may be cultivated or different types of plants may be cultivated in the cultivation containers of each stage.

Further, not only ornamental plants such as flowers and foliage plants, but also edible plants such as herbs can be cultivated.
In particular, if it is used for cultivation of greenhouse strawberries, which requires a high cost for heat sources, it can be expected to yield many times in space.
