초록
본 연구는 시험용 수집형 자주식 두류 수확기를 설계·제작하여 예취·건조된 나물 콩을 대상으로 수확작업 성능을 파악하였다. 수확시험은 수확기의 엔진 회전속도 2000, 2400, 2800rpm, 작업속도 0.6,1.0, 1.4m/s의 설정에 따라 수집 손실비율, 배진 손실비율 등 수확손실과 수확된 곡물 품질로서 완전립비율, 손상립 비율, 미탈곡립 비율, 이물질 비율을 분석하였으며, 그 외 수확된 나물 콩의 발아세와 발아율, 작물 재배 폭과 작업속도를 고려한 작업능률을 조사·분석하였다. 시험기는 운전조건이 엔진 회전속도 2800rpm, 작업속도 1.0m/s일 때 가장 좋은 작업 성능을 보인 것으로 판단되며, 이 때 수집 손실비율 약 2.7%, 배진 손실비율 약 0.5%, 총 손실비율 약 3.1%, 완전립 비율 약 99.3%, 손상립 비율약 0.2%, 미탈곡립 비율 약 0.0%, 이물질 비율 약 0.2%의 작업 성능과 수확된 나물 콩의 발아세, 발아율은 약 100%, 71.7%를 보여 국외 보통형 콤바인 보다 곡물 손실이 적고, 수확 곡물의 품질도 높아 우수한 작업 성능을 보인 것으로 나타났다. 또한 시험기는 나물 콩의 수확시험 조건이 불량한 상태에서도재배 폭이 약 2m인 3조 예취·건조 나물 콩을 약 1.0m/s의 작업속도로 수집·탈곡할 수 있어서 유효포장작업능률은 약 50a/h 정도일 것으로 판단되었다.
Abstract
To evaluate performance of the experimental pick-up type pulse crop harvester for harvestingsprout bean, its pick-up and discharging grain loss ratios, grain quality such as whole grainratio, damaged grain ratio, unthreshed grain, and foreign material ratio in grain tank, germinationrate of threshed grain, and theoretical field capacity of the harvester were analyzed according toengine speeds of 2000, 2400 and 2800 rpm and harvesting speeds of 0.6, 1.0 and 1.4 m/s. It isconsidered that the harvester showed optimum performance at the engine speed of 2800 rpmand the harvesting speed of 1.0 m/s, and then average pick-up grain loss ratio of 2.7%,discharging grain loss ratio of 0.5%, whole grain ratio of 99.3%, damaged grain ratio of 0.2%,unthreshed grain ratio of 0.0%, foreign material ratio of 0.2%, and germination rate at 8 daysafter seeding of 72.8% were shown. It is considered that the harvester has lower grain loss andhigher grain quality than the imported bean combines. And also as it could harvest 3 rows ofcut and dried sprout bean crop width of which was about 2 m, its effective field capacity wasestimated for about 50 a/h.
