타격식 참깨탈곡기 개발
Development of hiting sesamer thresher
초록
참깨탈곡의 생력기계화를 위해 일관작업이 가능한 참깨탈곡기를 개발하여 시험한 결과를 요약하면 다음과 같다. 가. 타격식 탈곡요인시험 결과 타격수 14, 17cpm에서 탈곡률은 98.5, 98.7%, 미탈곡률은 1.1, 1.0%, 배출구 손실률은 0.4. 0.3%로 가장 양호하게 나타났다. 나. 타격식 탈곡물의 정선요인시험결과 경사 12
Generally, sesame are dried on the field after being harvested in Korea. Since harvesting season is rainy autumn and sesame drying is mainly affected sun and natural wind, it is difficult to dry sesame in time. Moreover, sesame threshing by hand is very laborious work. Therefore, tractor mounted sesame thresher which threshes sesame bundles fed in upside down and conveyed along threshing bar was developed to mechanize sesame threshing and to reduce labor cost in this research. the thresher was equipped with a threshing bar which beats sesame bundles and a three layer sieve which screens sesame. The results are summarized as follows ; 1 The sesame thresher was consisted of a hitting-stick, a feeding chain conveyor, a threshing bar, conveyor belt, and the three-layer shaking sieve. 2. In threshing test, prototype thresher showed maximum threshing ratio 98.5%, 98.7% at 14, 17 cpm beating rate respectively. 3. In screening test, prototype sieve showed maximum threshing ratio 97.2% at 12
