Description

{Hydroponics cultivation apparatus}

The present invention relates to a hydroponic cultivation apparatus, and more particularly, to a hydroponic cultivation apparatus capable of adjusting the height of a vegetation mat planted with plants according to growth of plants, thereby facilitating the growth of the plants and artificially controlling the cultivation environment of the plants To a hydroponic cultivation apparatus.

Hydroponics has the advantage of reducing the use of pesticides and producing environmentally friendly vegetables, and has the great advantage of artificially controlling the rhizosphere environment.

Therefore, interest in hydroponic cultivation has been greatly increased, and in fact hydroponics is increasing rapidly. In addition, hydroponic cultivation has an advantage that it is possible to supply appropriate nutrients according to specific crops and cultivation environment by mixing specific nutrients into a culture medium, and is particularly advantageous for cultivation of organic vegetables.

According to this trend, various hydroponic cultivation apparatuses have been developed and marketed on the market.

However, most hydroponic cultivation systems use a system that feeds the cultures directly to growing vegetables, which are not suitable for small-scale use at home. Today, even in many households, direct use of small-scale cultivation equipment is used to directly grow and consume vegetables. Most commercial cultivation apparatuses are not suitable for small-scale cultivation of such households.

In addition, there is a disadvantage in that the system is equipped with a system for directly supplying the culture liquid to the vegetables, so that the culture liquid is supplied excessively or excessively. Accordingly, development of a cultivation apparatus capable of constantly supplying the culture liquid has been urgently required even without continuous management.

Korean Patent No. 10-1372185 discloses a hydroponic cultivation apparatus.

The hydroponic cultivation apparatus described above is an hydroponic cultivation apparatus capable of easily cultivating organic vegetables. The hydroponic cultivation apparatus includes an outer water tank for containing the culture liquid, an inner water tank installed inside the outer water tank, A water tank pump for introducing the culture liquid of the external water tank into the interior of the internal water tank and allowing the culture liquid to flow out through the outflow portion, a water level control unit installed at the side of the internal water tank for maintaining the water depth of the internal water tank constant, And is connected to the lower surface of the mat, is immersed in the culture liquid of the inner tank to a certain depth, and is supplied with the culture liquid to be supplied to the plants.

However, since the hydroponic cultivation apparatus is cultivated with the plant exposed to the outside, it is difficult to artificially control the cultivation environment because the external environment greatly affects the plant growth.

In addition, the hydroponic cultivation apparatus germinates plants grown on a mat provided on the inner water tank. At this time, the root of the plant grows toward the inner tank where the nutrient solution is stored. As the plant grows larger, the root becomes larger. However, since the space of the inner tank is constant, the roots of the plant are concentrated in the inner tank according to the growth of the plant. have.
