Description

분무식 수경 재배장치{An apparatus for aeroponics}An apparatus for aeroponics

본 발명은 수경 재배장치에 관한 것으로서, 더욱 상세하게는 분무노즐을 이용하여 입자상태의 양액을 분무하여 육묘를 기르는 분무식 수경재배 장치에 관한 것이다.The present invention relates to a hydroponic cultivation device, and more particularly, to a spray-type hydroponic cultivation device for growing seedlings by spraying a particulate nutrient solution using a spray nozzle.

일반적으로 수경재배(Hydroponic)란 영양소가 들어있는 양액 내에 뿌리를 담가서 식물을 생장시키는 것을 말한다. 산업발달에 의한 농경지의 감소와 사계절 소비화 경향에 대응하기 위하여, 무공해재배 및 신선도 유지를 도모할 수 있는 수경재배농법이 확산되고 있는 실정이다.In general, hydroponics refers to growing plants by immersing the roots in a nutrient solution containing nutrients. In order to cope with the decrease in agricultural land due to industrial development and the trend of seasonal consumption, hydroponics farming methods that can promote pollution-free cultivation and maintain freshness are spreading.

상기한 수경재배는 그 재배방식에 따라 크게 순수수경(Water culture)과 고형배지형(Medium culture)으로 나누어진다. 이들 중 순수수경이란 식물의 뿌리를 지탱하는 물질로 고형배지가 없는 배양액에서 키우는 것으로 담액수경(DFT:Deep Flow Technique), 분무수경(Aeroponics) 등으로 나눈다.The above-mentioned hydroponics is largely divided into pure hydroponic (Water culture) and solid medium type (Medium culture) according to the cultivation method. Among them, pure hydroponics is a material that supports the roots of plants and is grown in a culture medium without a solid medium. It is divided into deep flow technique (DFT) and aeroponics.

상기 담액수경은 작물의 뿌리가 양액에 상시 담겨진 상태로 영양분을 공급받도록 되어 있어, 뿌리의 호흡작용을 저해하여 뿌리 부분이 부패하여 작물의 성장이 극히 저조한 문제점이 있었다. 이러한 담액수경의 문제점을 해결하기 위하여, 문무수경에서는 분무노즐을 이용하여 입자상태의 양액을 공중에 메 달린 식물의 뿌리를 향하여 분무하는 방식을 적용하였다. The fresh water hydroponics has a problem in that the roots of crops are supplied with nutrients in a state where they are always immersed in the nutrient solution, and thus the respiration of the roots is inhibited, so that the root parts are rotted, so that the growth of the crops is extremely poor. In order to solve this problem of fresh water hydroponics, a method of spraying the nutrient solution in the form of particles toward the roots of plants suspended in the air was applied using a spray nozzle in the hydroponic system.

상기한 바와 같은 분무식 수경재배는, 재배하는 육묘의 생육 상태에 따라 공급하는 양액의 농도나 공급량을 다르게 하여야 한다. 또한 통상적으로 적용하는 엘이디(LED) 조명을 통해 제공하는 광의 최적 조도는 육묘의 생육시기 및 정도에 따라 달라진다. In the spray-type hydroponics as described above, the concentration or supply amount of the nutrient solution to be supplied should be different depending on the growth state of the grown seedlings. In addition, the optimal illuminance of light provided through commonly applied LED lighting varies depending on the growing time and degree of seedlings.

그런데 종래 분무식 수경재배에서는 공급하는 양액의 농도 및 공급량, 광의 조도 등에 대해, 작업자(사용자)의 경험에 근거하여 임의적으로 적용하고 있는 실정이다. 따라서 작업자의 경험치나 숙련도에 따라 양육되는 육묘의 성장속도 및 생산량이 큰 차이를 갖게 되고, 최적상태의 분무식 수경재배가 실현되지 못하는 한계를 가진다. However, in the conventional spray-type hydroponics, the concentration and supply amount of the nutrient solution supplied, the illuminance of light, etc., are arbitrarily applied based on the experience of the operator (user). Therefore, there is a big difference in the growth rate and production of seedlings raised according to the experience or skill level of the operator, and there is a limit in that the spray-type hydroponics in an optimal state cannot be realized.

대한민국 공개특허 제10-2018-0040917호(발명의 명칭 : 분무 수경 재배 시스템)Republic of Korea Patent Publication No. 10-2018-0040917 (Title of the invention: spray hydroponic cultivation system)

FIG. 2 is a diagram for explaining the operational relationship of the vision system unit, the data storage unit, and the environment control unit shown in FIG. 1 .

본 발명은 도면에 도시된 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 본 기술 분야의 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 다른 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 기술적 보호 범위는 첨부된 청구범위의 기술적 사상에 의하여 정해져야 할 것이다.Although the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.

도 1은 본 발명의 실시예에 따는 분무식 수경 재배장치를 간략하게 나타낸 측면도이고, 도 2는 도 1에 나타낸 비전시스템부, 데이터저장부 및 환경제어부의 작동관계를 설명하기 위한 도면이다.1 is a side view schematically showing a spray-type hydroponic cultivation apparatus according to an embodiment of the present invention, and FIG. 2 is a view for explaining the operational relationship of the vision system unit, the data storage unit and the environment control unit shown in FIG. 1 .

도면을 참조하면, 본 발명의 실시예에 따른 분무식 수경 재배장치(10)는, 복수개의 트레이부(100)와, 복수개의 양액분무부(200)와, 복수개의 조명장치부(300)와, 비전시스템부(400)와, 데이터저장부(500)와, 환경제어부(600)를 구비한다.Referring to the drawings, the spray-type hydroponic cultivation apparatus 10 according to an embodiment of the present invention includes a plurality of tray parts 100 , a plurality of nutrient solution spraying parts 200 , and a plurality of lighting device parts 300 , and , a vision system unit 400 , a data storage unit 500 , and an environment control unit 600 .

도 1과 같이, 상기 트레이부(100)에는 다수의 재배대(110)가 상하로 다단 배치되어 있다. 그리고 이러한 재배대(110)에는 식재된 육묘(S)의 뿌리(r)가 아래로 통과하는 다수의 뿌리통과공이 형성되어 있다. 즉, 육묘 뿌리(r)는 재배대(110)의 뿌리통과공을 관통하여 노출된 상태로 재배대(110)의 하방을 향해 자란다. As shown in FIG. 1 , a plurality of cultivation tables 110 are vertically arranged in multiple stages in the tray unit 100 . In addition, a plurality of root passage holes through which the roots (r) of the planted seedlings (S) pass downward are formed in the cultivation table 110 . That is, the seedling root r penetrates the root through hole of the cultivation table 110 and grows downward of the cultivation table 110 in an exposed state.

상기 양액분무부(200)는, 다단 배치된 상기 재배대(110)의 하부에 각각 배치된다. 이러한 양액분무부(200)는 재배대(110)에 식재된 육묘 뿌리(r)로 양액을 분무하는 복수개의 분무노즐(210)을 구비하고 있다. The nutrient solution spraying unit 200 is disposed at the lower portion of the culture table 110 arranged in multiple stages, respectively. This nutrient solution spraying unit 200 is provided with a plurality of spray nozzles 210 for spraying the nutrient solution to the seedling roots (r) planted on the cultivation table (110).

상기 조명장치부(300)는 다단 배치된 상기 재배대(110)의 상부에 각각 배치된다. 그리고 이러한 조명장치부(300)에는 상기 재배대(110)에 식재된 육묘(S)로 광을 조사하는 조명장치(310)를 포함한다. 여기서 조명장치(310)로는 하나의 이상의 파장을 갖는 광을 조사하는 엘이디(LED) 광원을 사용하는 것이 일반적이지만, 조명장치가 엘이디 광원으로 한정되는 것은 아니다. The lighting device 300 is disposed on the upper portion of the culture table 110 arranged in multiple stages, respectively. And the lighting device 300 includes a lighting device 310 for irradiating light to the seedlings S planted on the cultivation table 110 . Here, as the lighting device 310, an LED light source irradiating light having one or more wavelengths is generally used, but the lighting device is not limited to the LED light source.

한편, 본 발명의 분무식 수경 재배장치(10)에서는, 도 1에 도시된 바와 같이 양액분무부(200)와 조명장치부(300) 사이에 방수 재질로 만들어진 방수패드(700)가 각각 설치될 수 있다 이러한 방수패드(700)는 상기 양액분무부(300)로부터 분무된 양액을 회수하는 역할을 수행한다.On the other hand, in the spray-type hydroponic cultivation device 10 of the present invention, as shown in FIG. 1 , a waterproof pad 700 made of a waterproof material is installed between the nutrient solution spray unit 200 and the lighting device unit 300 , respectively. This waterproof pad 700 serves to recover the nutrient solution sprayed from the nutrient solution spray unit 300 .

좀 더 부연 설명하면, 상기 방수패드(700)는 선단에서 후단으로 갈수록 하향 경사지게 설치될 수 있다. 이에 따라 양액분무부(200)에서 분무된 후, 아래로 떨어지는 양액은 방수패드(700)를 통해 중력에 의해 선단에서 후단으로 이동하게 된다. 여기서 상기 방수패드(700)의 후단에는, 도시하지는 않았지만 양액회수통을 설치하여 방수패드(700)를 통해 이동하는 양액을 저장할 수 있다. In more detail, the waterproof pad 700 may be installed to be inclined downward from the front end to the rear end. Accordingly, after being sprayed by the nutrient solution spray unit 200 , the nutrient solution falling down moves from the front end to the rear end by gravity through the waterproof pad 700 . Here, at the rear end of the waterproof pad 700 , although not shown, a nutrient solution collection container may be installed to store the nutrient solution moving through the waterproof pad 700 .

상기 양액회수통(미도시)에 저장된 양액은 양액공급부(미도시)를 통해 양액분무부(200)로 공급하여 순환될 수 있도록 할 수 있다. 이를 위해 상기 양액공급부는, 도시하지는 않았지만 양액회수통과 양액분무부(200)를 연결하는 양액의 공급라인(파이프)과 공급펌프를 구비하는 것이 바람직하다. 이와 같이 양액이 순환될 수 있는 구조를 채용함으로써 양액의 낭비를 없애고, 시스템의 효율적인 운용이 가능해진다. The nutrient solution stored in the nutrient solution collection container (not shown) may be supplied to the nutrient solution spray unit 200 through a nutrient solution supply unit (not shown) to be circulated. To this end, although not shown, the nutrient solution supply unit preferably includes a nutrient solution supply line (pipe) and a supply pump connecting the nutrient solution recovery passage and the nutrient solution spray unit 200 . By adopting a structure in which the nutrient solution can be circulated in this way, waste of the nutrient solution is eliminated, and the efficient operation of the system becomes possible.

상기한 바와 같은 본 발명의 분무식 수경 재배장치(10)에서, 상기 비전시스템부(400)는 다단 배치된 재배대(110)의 일측에 각각 설치되어 육묘 뿌리(r)의 생육상태를 감지한다. 이를 위해 비전시스템부(400)는 카메라와 같은 복수개의 영상촬영장치(410)를 포함한다. 여기서 비전시스템부(4000)의 영상촬영장치(410) 통해 감지하는 육묘 뿌리(r) 생육상태로는 길이, 두께 및 색상 중 선택된 어느 하나 이상일 수 있으나, 이에 한정된 것은 아니다. In the spray-type hydroponic cultivation apparatus 10 of the present invention as described above, the vision system unit 400 is installed on one side of the multi-stage culture table 110, respectively, to detect the growth state of the seedling root r. .
