지역 밭작물 생산의 생력화를 제고하기 위하여 개발한 복합 작업기(BG-1200AB)를 트랙터(DK753C:55kW)에 장착하고 평두둑 복합기의 작업동력 및 견인력을 평가하였다. 견인 동력계의 여섯 로드셀에서 측정된 신호는 분력식에 따라 견인력(Ph), 수직력(Pv) 및 수평력(Ps)으로 계산되었고 각축에 생성되는 모멘트(Mh, Mv, Ms)를 계산하여 작업상태를 분석하였다. 견인력은 주로 토양의 다짐상태에 따라 영향을 받으며 평균 108-578kgf의 견인력에 대하여 견인동력은 0.5~0.9kW 정도였다. 작업속도는 0.4~2.0km/h 범위에서 절단피치가 증가할수록 비견인력(specific draft)이 감소하는 감소지수 관계를 보였다. PTO 토크는 경심에 따라 평균 160~350N·m으로 측정되었으며, 로터리 경운과 펌프 구동에 사용되는 PTO동력(9.0~19.8kW)이 소비동력의 대부분을 차지하였다. 따라서 복합기의 운용은 견인 동력효율에 맞춰져서는 이점이 나타나지 않으며 작업결과의 질 즉, 파종상토와 멀칭작업의 품질에 초점이 맞춰져야 한다. 상부견인 또는 하부견이에 따라 부하의 위치와 크기가 변화되고 작업기의 균형이 결정되므로 작업기의 고품질 작업을 추구하기 위하여 하부 링크의 독립적 제어를 제안한다.
The integrated tractor implement, developed for saving labor in the production of local upland crop was assessed to determine the operating power and draft using a draft dynamometer and torque meter. Components of draft are measured using six load-cells of the draft dynamometer, and moments of the ...
