Description

Hydroponic cultivator{a device for hydroponics}

The present invention relates to a hydroponic cultivator, and more specifically, it is possible to stably cultivate a plant without separately injecting a nutrient solution, and it is possible to prevent the acidity of the culture medium from changing without using a drug to prevent disease. It is related to a hydroponic cultivator capable of stably cultivating a plant.

In general, hydroponic cultivation refers to cultivation of plants with a culture solution containing nutrients necessary for the plant to grow without using soil.

Hydroponic cultivation is achieved by supplying a culture solution in which various nutrients are dissolved in water. That is, plant roots are grown in a culture medium containing nutrients.

In addition, plants that can be grown by hydroponic cultivation include tulips, narcissus, taro, sweet potato, onion, lucky tree, ginseng, etc. with beard roots. Can be easily grown at home.

This hydroponic cultivation was conducted in the 1930s by the American W.F. Designed by Gericke, it consists of a cultivation tank, a low-liquid tank, a circulation pipe, and a liquid pump, and other oxygen supply methods and devices are also required.

Hydroponic cultivation method that can promote mass production, pollution-free cultivation, and maintain freshness of agricultural products through four seasons cultivation in order to cope with the trend of consumerization of the four seasons regardless of the production season (season) of the reduction of agricultural land due to recent industrial development. This situation is spreading.

In the hydroponic cultivation method of such agricultural products, hydroponic cultivation in which plants are grown using only water in which various necessary nutrients are dissolved without using soil, grows seedlings in seedlings, grows them to an appropriate size, and cultivates nutrients while transplanting them. The cultivation plate is formed by molding a general hard synthetic resin or absorbent material such as glass wool into a plate shape, and the cultivation plate is formed by forming a cup-shaped planting hole to insert and fix the root portion of the plant. It can be fixed.

Therefore, by using a separate support frame, the cultivation plate is fixedly installed on the upper side and a predetermined height of the ground, and after the plant is planted on the cultivation plate, the plant can be hydroponically cultivated by supplying a culture solution to the lower side of the cultivation plate. In the existing hydroponic cultivation apparatus used for such hydroponic cultivation, plants are actually accommodated, cultured, and supplied with nutrients through a nutrient solution supply pipe on a certain standard substrate equipped with a drainage means to flow slowly in a full state and planted thereon. The cultivation plate in which the crop is transplanted is placed close to the ball so that the roots of the crop can absorb nutrients from the nutrient solution. Recently, an upgraded hydroponic cultivator is required to increase productivity and lower costs.

As an example of such a hydroponic cultivator, a technique described in Korean Patent Registration No. 10-1873374 as shown in FIGS. 1 and 2 has been proposed, the technical feature of which is a tray 10 having an open top in a rectangular parallelepiped shape, A plate-shaped support plate 22 and a fixed frame 20 having a plurality of support portions 21 supporting the support plate 22 are further included, wherein the trays 10 are each of a long side. The first LED 13 positioned at a predetermined position of the opposing inner wall, the inlet 15 positioned at one end region of one side of the end side, and the other end of one side of the end side To the water surface of the nutrient solution filled in the hollow of the tray 10 and the outlet 12 located in a predetermined area of the lower surface, and the outlet portion 12 located at the other end area of the other side of the region and the end face. Further comprising a floating seedling plate 14, the fixed frame 20, the second LED (24) located at a predetermined position along the long side of the lower portion of the base plate 22, and the long side of the base plate (22) And a through hole 23 at a diagonal position among the corner areas where the short sides meet, and the tray 10 and the fixed frame 20 are sequentially and repeatedly stacked.

However, the technique described in Korean Patent Registration No. 10-1873374 has the advantage of cultivating functional plants by controlling the amount of light according to the plant's growth process and purpose of use through a hydroponic cultivator, but it is necessary to additionally supply nutrient solution.
