STRUCTURE OF SHAKING TYPE WINNOWER IN COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To increase the screening performance of a rice grain winnower by smoothly flowing the winnowing wind to the winnowing machine body. SOLUTION: A rice plant-reaping unit is arranged on the front edge of the machine body and the threshing unit is set in the rear of the reaper. The shaking separation unit is placed in the lower position of the threshing unit and the shaking separator is shakably set in the shaking separation unit. The first winnower is arranged lower in front of the shaking separator and the second winnower is arranged lower in the rear of the shaking separator. In the combine harvester, the width of the first winnower is made narrower than the inner width of the frame of the machine body and the frame of the shaking machine for the shaking separator is arranged between the left-right outer side of the first winnower and the left-right inner side of the machine frame so that the first winnower and the shaking separator may be overlapped each other in the side view.
