Abstract

The automatic operating system was designed and built to work manless multipurpose in greenhouse. The system proved to be a reliable system for performing multipurpose functions. Its development involved the integration of moving part, height control part, watering part, ventilation part and inhalation part. The moving part was able to be moved it on the rail installed in greenhouse, the height control part controled it up and down by height of the crops, the watering part sprinkled a agricultural medicines on the crops and the ventilation and the inhalation part ventilated and inhaled different thing and vermin which were attached on crops. Based on the results of this study the following conclusions were made: The moving velocity was changed 0.047 - 0.027 m/s by the dial transfer. The velocity within 50 cm from center of the entrance was 0.2 m/s. The watering volume of spray increased as the pressure of spray was high. The difference of spray pressure between 10 kg/$\textrm{cm}^2$ and 15 kg/$\textrm{cm}^2$ was 60 ml, but that of spray pressure between 15 kg/$\textrm{cm}^2$ and 20 kg/$\textrm{cm}^2$ was 20 ml. The average speed of a current of inhalation was 3.64 m/s and the inhalation flux of inhalation was measured 0.044 ㎥/s by using glues seed and styrofoam.

시설원예 작업의 생력화을 위해 화훼온실, 육묘장, 잔디온실 및 분화재배온실에서 사용할 수 있는 다목적 자동작업장치를 개발하였다. 본 시스템의 구성은 주행부, 높이조절부, 살수부, 송풍부 및 흡입부로 되어 있다. 다목적 자동작업장치를 이용하여 다음과 같은 결과를 얻었다. 다이얼 변화에 따른 속도는 0.047~0.027 m/s로 나타났고, 에어커튼의 풍속은 고속, 중속, 저속에서 3.9 m/s, 3.6m/s, 3.4m/s로 나타났으나, 중앙 50cm의 위치에서는 0.2 m/s정도로 차이가 없었다. 관수압력이 높을수록 관수량이 많아졌으나 10kg/$\textrm{cm}^2$와 15kg/$\textrm{cm}^2$에서의 차이는 약 60ml, 15kg/$\textrm{cm}^2$와 20g/$\textrm{cm}^2$의 사이에는 약 20m1의 차이를 보였다. 흡입은 해충과 유사한 3~4 mm정도의 스티로폼 가루 및 풀 씨앗을 이용하여 측정한 결과 평균 유속은 3.64 m/s이고, 흡입유량은 0.044 ㎥/s이었다.
