초록
밭농업의 생력화를 위해 개발된 둥근두둑 복합작업기는 로터리를 기본으로 관행의 작업순서에 맞게 경운, 휴립, 피복 및 파종 작업기를 순차적으로배치하여 통합시킨 형태로서 로터베이터의 특성에 영향을 받는다. 본 연구에서는 작업속도에 따른 작업품질을 평가하고 이에 따라 최적 작업능률및 운용비용을 분석하였다. 복합기의 작업속도에 따른 작업품질을 평가할 때 공칭 작업속도 4km/h까지 토괴의 응집크기와 멀칭 및 파종구 상태가적절하였다. 주행기어의 단수를 높여 작업속도를 증가시키면 작업시간 단축에 따른 고정비 및 변동비의 절감과 연료효율의 제고로 인한 연료비의절감을 기대할 수 있다. 작업능률과 비용평가에 있어 공칭 작업속도 4km/h에서의 부담면적은 24.3ha/yr 이며, 단위면적(10a)당 총비용과 연료비는각각 ￦60,352/10a 및 ￦5,712/10a으로 총비용에서 연료비가 차지하는 비율은 9.5%로 연료의 절감은 제한적이었다.
Abstract
Since the round-ridge integrated implement, developed for the labor saving in upland farming is based on a rotary system consisting of tillage, ridge, mulching and sowing machines in the order of conventional farming, it affected by the characteristics of rotavator. The objective of the study was to evaluate the seedbed quality, field capacity and operation cost to the forward speed. When evaluating the work quality of the integrated implement for forward speed, the seedbed results of aggregate clod size and form of mulching were acceptable up to a nominal working speed of 4 km/h. In terms of field capacity and operation cost of the integrated implement, the total cost and fuel cost per unit area (10a) are ￦60,352/10a and ￦5,712/10a, respectively for the arable area is 24.3 ha/yr. Increasing the forward speed by increasing gear step could save the fixed and variable costs due to the reduction of working time and save fuel cost due to the improvement of fuel efficiency. However, the saving of fuel is limited because the share of fuel cost was 9.5%
