  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an explanatory view for explaining a hydroponic cultivation apparatus 1 with a container hanging member 2, and FIG. 2 is an explanatory view for explaining a container hanging member 2 in the hydroponic cultivation apparatus 1 with a container hanging member 2 of FIG. 1. 3-5 is explanatory drawing explaining the hydroponic cultivation apparatus 1 with the container suspension member 2 of FIG.

  The hydroponic cultivation apparatus 1 includes a planting container 3 and a storage container 4 that stores the culture solution 6 to be supplied to the plant in the planting container 3 and stores the planting container 3 in a floating state. . The planting container 3 contains and uses the medium 5.

  When plant seeds and seedlings are placed on the medium 5, the seeds and seedlings absorb the culture solution 6 raised by the capillary action of the medium 5, so that the plants grow.

  As shown in FIG. 1, the liquid storage container 4 is formed in a tapered bottomed cylindrical shape that gradually expands from the lower part to the upper part.

  The planting container 3 is formed by integrally forming a planting room 34 and an annular float chamber 33 that surrounds the planting room 34 and opens downward. A large number of through holes 321 are provided radially and concentrically in the bottom wall 31 of the planting room 34, and the large number of through holes 321 constitute a water flow portion 32.

  In the planting room 34, the culture medium 5 made of a porous material is accommodated. For the culture medium 5, for example, a rock wool molded product, various foamed resin molded products such as urethane and phenol, a molded product made of a vegetable fiber, an inorganic fiber, or the like formed in a block shape or a mat shape is used.

  The annular float chamber 33 is integrally formed with the planting chamber 34, is formed in a U-shaped cross section that opens downward, and is provided with a predetermined interval (for example, an interval of 90 degrees) in the circumferential direction. Is divided into four tubules 36. Due to the configuration of the annular float chamber 33 provided with such tubules 36, the tubules 36 floated on the culture medium are filled with a gas such as air to form a buoyant body, thereby requiring a separate buoyancy body. The planting container 3 can be suspended on the culture solution 6 without doing so.

  The outer wall surface of the annular float chamber 33 is formed in a substantially square shape in plan view. The four corners of the outer wall surface of the annular float chamber 33 form a proximity surface 332 that is formed in a curved shape that protrudes outward. The proximity surface 332 is formed so as to substantially follow the inner wall of the liquid storage container 4. A space between adjacent adjacent surfaces 332 is formed as a flat surface, and forms an isolation surface 331 having a space where fingers can be inserted between the inner wall of the liquid storage container 4.

  Thus, since the space | interval which can insert fingers is formed between the inner walls of the liquid storage container 4, it is easy to grasp the planting container 3 and to take in and out from the liquid storage container 4.

  Below the bottom wall 31 of the planting room 34, the leg part 35 is arrange | positioned at circular arc shape. By arranging the legs 35 on the bottom wall 31 of the planting room 34, the planting room 34 can be used even when the culture solution 6 in the storage container 4 is in a drought state or approaches a drought state. The bottom wall 31 does not contact the bottom surface of the liquid storage container 4.

  The case where a plant is grown in the hydroponic cultivation apparatus 1 will be described with reference to FIG. 3. After the medium 5 is accommodated in the planting room 34 and seedlings are planted in the medium 5, the planting container 3 is placed. Is placed in the liquid storage container 4 and the legs 35 are placed on the bottom surface of the liquid storage container 4.

  Subsequently, the culture solution 6 is applied little by little from above the culture medium 5, and the culture solution 6 is poured into the storage container 4 until the planting container 3 floats on the culture solution 6.

  In the state where the planting container 3 floats in the culture solution 6, the lower half of the medium 5 in the state accommodated in the planting room 34 is immersed in the culture solution 6, and when the seedling roots are short, the medium When the seedling absorbs the culture solution 6 by the capillary phenomenon of 5 and the roots of the seedling grow and become long, the seedling absorbs directly from the culture solution 6 in which the medium 5 is immersed.

  Since the total amount of the culture solution 6 decreases due to absorption by the seedling and natural evaporation and the liquid level gradually decreases, the culture solution 6 may be replenished to the storage container 4 each time. By replenishing the liquid storage container 4 with the culture solution 6, the floating state of the planting container 3 can be realized again.

  As shown in FIG. 4, when the cultivated plant grows and the planting container 3 does not float on the culture solution 6 due to its own weight, or when the planting container 3 tilts on the culture solution 6, etc. For this, it is necessary to adjust the height of the plant in the planting container 3 to a height at which the culture solution 6 can be absorbed by using the container suspension member.

  The container suspension member 2 is attached to the peripheral wall 41 of the liquid storage container 4, and the planting container 3 is arranged by the container suspension member 2 so that the planting container 3 is suspended from the liquid storage container 4. It is comprised so that it may support.

  As shown in FIG. 2, the container suspension member 2 is formed using a wire made of a spring steel material, and the container storage member 2 can be used in accordance with the degree of plant growth. It is comprised so that attachment or detachment to the surrounding wall 41 of 4 is possible.

  Since the container suspension member 2 is formed of a spring steel material, when the container suspension member 2 is attached to the liquid storage container 4, the support portion 23 of the container suspension member 2 is against the wall surface of the liquid storage container 4. In this embodiment, the support portion 23 is attached so as to face the central direction of the liquid storage container 4 so as to be vertical. Since the container suspension member 2 is attached in this way, the planting container 3 can be easily attached to the container suspension member 2.

  The container suspension member 2 has a straight portion 22. In the container suspension member 2, a hooking portion 21 that is hooked on the peripheral wall 41 of the liquid storage container 4 is curved on one end side of the linear portion 22, and is formed on the lower portion of the outer wall of the annular float chamber 33. The support part 23 which attaches and supports the said planting container 3 is formed by curve.

  For example, the latching portion 21 attached to the peripheral wall 41 of the liquid storage container 4 has a shape that sandwiches the peripheral wall 41 of the liquid storage container 4 from both the inside and the outside by a spring force. The support part 23 attached to the lower part of the outer wall of the annular float chamber 33 is curved with a gentler inclination than the hooking part 21, and is inclined at an angle at which the outer wall of the annular float chamber 33 is easily supported by the curved part of the support part 23. Is configured to do. For example, the inclination angle of the support portion 23 with respect to the straight portion 22 is preferably an acute angle.

  Plants can be cultivated while maintaining an appropriate moisture state with a simple configuration in which one end side of the container suspension member 2 is attached to the storage container 4 and the planting container 3 is hooked on the other end side.

  Moreover, the front-end | tip 211,231 of the latching part 21 and the support part 23 which were provided in the container suspension member 2 are formed in the curve shape which has a circular arc.

With such a configuration, the tip 211 of the latching portion 21 is formed in a rounded shape, so that the container suspension member 2 can be easily attached to the peripheral wall 41 of the liquid storage container 4. Further, since the tip 231 of the support portion 23 is formed in a rounded shape, safety is high.

  Based on FIG. 5, for example, a case where a plant that grows excessively is grown in the hydroponic cultivation apparatus 1 will be described. In the state where the planting container 3 is detached from the liquid storage container 4, the container suspension member 2 is latched. The part 21 is inserted into the upper edge of the peripheral wall 41 of the liquid storage container 4 and attached.

  In the case where a plurality of container suspension members 2 are attached, it is preferable to place the container suspension members 2 at positions where the container suspension members 2 face each other because the planting container 3 suspended by the container suspension member 2 is stabilized.

  When the container suspension member 2 is attached to the peripheral wall 41 of the storage container 4, the container suspension member that protrudes perpendicularly to the surface of the peripheral wall 41 of the storage container 4 so as to support the outer wall of the planting container 3 from below. The planting container 3 is attached to the support part 23 of 2.

  When the planting container 3 is attached, the culture solution 6 is gradually poured over the medium 5. At this time, the injection amount of the culture solution 6 is adjusted so that a space (gap) is provided between the bottom surface of the planting container 3 and the culture solution 6 surface. By providing a space (gap) and setting the height position of the planting container 3, root decay of the plant can be prevented. In addition, the container suspension member 2 may be attached to the peripheral wall 41 of the storage container 4 into which the culture solution 6 has been poured in consideration of the height position of the planting container 3, and the planting container 3 may be suspended. .

  Since the planting container 3 can be suspended from the storage container 4 by the container suspension member 2 by the hydroponic cultivation apparatus 1 with the container suspension member 2 as described above, when the plant grows and becomes large Even so, the planting container 3 does not sink, and the plant can be cultivated while maintaining an appropriate moisture state.

  The container suspension member 2 described above is preferably subjected to rust prevention treatment. Moreover, it is suitable that the height position of the planting container 3 can be set and changed according to the degree of plant growth using a plurality of container suspending members 2 having different sizes.
