Description

[Detailed description of the invention] Industrial application field This invention relates to a hydroponic cultivation device for growing fruit vegetables such as tomatoes, cucumbers, and melons mainly outdoors, such as on home balconies, terraces, or rooftops. .

Conventional technology and problems Conventional home hydroponic cultivation equipment is mainly used for leafy plants such as trefoil, spinach, and spinach, or bulbs, and is not intended for tall fruit vegetables. In order to cultivate it, it was necessary to prepare a separate support, and the work of setting it up was also very troublesome.

Means for Solving the Problems This invention aims to eliminate the drawbacks of conventional devices and provide a hydroponic cultivation device for home use that is suitable for growing tall fruits and vegetables.

In other words, the gist of this invention is the structure of ``a hydroponic cultivation device characterized by providing a leg stand that can be hung freely around the periphery of a nutrient solution tank, and supporting a support column that can be raised and lowered by the leg stand.'' It is something to do.

The present invention is also characterized in that the support column is provided with an arm that projects laterally, and a guide rod is provided on the arm in a downward direction.

Function Since the present invention is constructed as described above, the support column can be supported by the nutrient solution tank in a freely latched manner via the leg stand.

Moreover, the guide rod supported by the support pillar can support the plant so that it does not fall over and guide it upward as the plant grows.

Embodiment The present invention will be described with reference to an illustrated embodiment. Reference numeral 1 denotes a nutrient solution tank in which nutrient solution a can be freely stored. Nutrient solution a
A plant cultivation bed 2 is floating on the upper surface, and a plant b
is being planted.

3 is an aeration device, which is provided in the center of the nutrient solution tank. This aeration device 3 consists of a pedestal 31 and a hollow cylinder 32 that is vertically installed in the center of the pedestal 31, and a pumping blade 33 is installed inside the hollow cylinder 32. Lifting wing 3
3 is connected to an upper motor 34 via a rotating shaft in a freely transmitting manner. A water inlet is opened at the bottom of the hollow cylinder 32, and a water outlet is opened at a donut-shaped saucer 35 provided so as to surround the upper part of the hollow cylinder 32. The nutrient solution a discharged into the saucer 35 overflows from the periphery of the saucer 35, flows through the flow tube 36 hooked to the periphery of the saucer 35, and flows back into the nutrient solution tank 1.

Reference numeral 4 denotes a leg stand, which includes a leg part 41 that can be freely hung on the periphery of the nutrient solution tank 1, and an adjustment shaft 4 that is vertically installed at the apex of the leg part 41.
It consists of 2. 5 is a support column, and adjustment shaft 4
2 so as to be slidably inserted therein, and can be latched at will by means of screws or the like. A guide rod 7 is provided hanging from the support column 5 via an arm 6. Incidentally, a cap 8 for rain protection is provided at the top of the support column 5.

As is clear from the above, the support column 5 is movable up and down with respect to the pedestal 4, and the guide rod 7 is provided hanging from the support column 5 via the arm 6, so that the support column 5 can be moved up and down with respect to the base 4. Even if the plant grows, there is no need to prepare a separate support for it, and it can be easily supported as the plant grows.

Effects of the invention As described above, the present invention has the effect that even when growing tall fruit and vegetables, it is possible to grow them so that they do not fall over without providing a separate support.
