초록
육상수조식 양식장에서 대상 어종별 급이 시간과 양을 정확하게 조절할 수 있는 자동먹이 공급장치의 개발을 위하여, 어종별 섭이 행동 패턴조사를 실시한 결과를 바탕으로 먹이공급장치의 정량조절장치 및 살포장치를 설계, 제작 하여 현장실험을 실시하였다. 먹이공급장치의 사료 조절방법은 로터 용적과 모터 회전수에 의해 사료 토출양이 조절되도록 제작하였다. 또한, 먹이공급장치의 살포장치는 프로펠러 날개의 회전에 의한 방식을 채택하여 사료를 원하는 장소에 뿌려주는 효과를 적용하였는데, 살포장치 날개의 지름은 250mm, 600rpm의 회전수일 경우, 최대 비산거리가 7.8m였다. 또한, 먹이공급장치의 살포방식을 단순살포방식과 다단변속살포방식의 2가지 방식을 비교한 결과, 다단변속 살포방식이 실험수조 내에 효과적으로 살포되었다.
Abstract
This paper introduces an auto-feeding system to exactly control the feeding time and the amount to cultured fishes in aquaculture industrial field. To reduce expensive costs or labors in this field, it was designed by the concept of controlling feed quantity exactly on the basis of fish's feeding behavior pattern in water tank. A feed control method of this system was developed for controlling feed amount by rotor capacity and motor rotated number. Moreover, a scattering section was selected by rotate way of propeller wing to scatter dried feed to designated site, and then, the diameter of its wing was 250mm and maximum scattering distance was 7.6m for 600rpm. Furthermore, the scattering ways were embodied 2 types such as a simplified way and a multistage shift way looks like a manual scattering. As a results, the multistage shift way is more effective to discharge the dried feed widely than the simple way in the water tank.
