Abstract

A spray-type hydroponic cultivation device according to one embodiment of the present invention comprises a cultivation bed, a cultivation tray placed on the cultivation bed, and a spraying means positioned below the cultivation tray and formed to spray a nutrient solution upward from the bottom portion of the cultivation bed, wherein the cultivation bed comprises a bottom portion having a predetermined length and width and a first side portion formed to form a predetermined height at both edges in the longitudinal direction of the bottom portion. The bottom portion is characterized by including a groove portion that is formed concavely toward the bottom and extends along the longitudinal direction in the inner central portion so as to position the spraying means, and an inclined portion formed to slope downward from both edges along the longitudinal direction of the groove portion toward the inner surface of the first side portion to collect the nutrient solution that is sprayed upward and then drained, and formed such that the height of the inner surface decreases from one end to the other end with respect to the longitudinal direction of the bottom portion, thereby guiding the collected nutrient solution to move from the one end to the other end.

Description

Spray-type hydroponic apparatus {APPARATUS FOR AEROPONICS} The present invention relates to a spray-type hydroponic cultivation device, and more specifically, to a spray-type hydroponic cultivation device that suspends crops and sprays nutrients onto their roots. Hydroponics is a method of growing terrestrial plants without soil using a nutrient solution (water mixed with a nutrient medium). It is a cultivation method that provides nutrients to plants by allowing the roots to absorb the nutrient solution, in which the nutrients necessary for plant growth are dissolved, instead of soil. Currently commercialized hydroponic systems have a problem in which the nutrient supply pipeline and the nutrient return line are located in the same place, obstructing the flow of the returned nutrient solution. This prevents proper drainage, and if the spray nozzle becomes submerged, it causes serious damage to the crops. For example, in Korean Patent Publication No. 10-2017-0071036, the supply and drainage of the cultivation water are carried out in a single cultivation water supply unit (10), so the flow of the nutrient solution is not smooth, which may result in a decrease in crop productivity.
