The present invention relates to a combine with an improved sorting and discharging structure. More specifically, the combine with an improved sorting and discharging structure sequentially performs a cutting process of cutting rice which is grown in a rice paddy and is to be harvested while moving along the rice paddy in which the rice is grown, a threshing process of threshing the cut rice, and a sorting process of separating mixed grains and chaff to collect the grains and discharge the chaff to the outside, thereby collecting the grains from which the chaff is removed. The cutting process, the threshing process, and the sorting process are sequentially performed.COPYRIGHT KIPO 2016본 발명은 개량된 선별 배출구조를 갖는 콤바인에 관한 것으로, 더욱 상세하게는 수확을 요하는 벼들이 재배된 논을 따라 자가 이동하면서, 논에 재배된 벼를 절단하는 절단공정과, 상기 절단된 벼를 탈곡하는 탈곡공정과, 혼입된 알곡과 검불을 분리하여 알곡은 포집하고 검불은 외부 배출하는 선별공정을 순차적으로 실시하여 검불이 제거된 순수한 알곡을 포집하는 개량된 선별 배출구조를 갖는 콤바인에 관한 것이다.
