The invention provides a threshing device, wherein the attachments such as straws and the like attaching to the surface of a screen are peeled off and the obstruction of swing screening shelves is avoided, thereby improving the screening efficiency and the threshing efficiency.A scraper (82) equipped with a rim part (82a) for peeling off the attachments attaching to the surface of the screen (23) is arranged to freely reciprocate along the length direction of the screen (23).In addition, a plurality of scrapers (82) arranged on the front and rear screens (23) are formed integratedly with the single plate (81) arranged along the swing direction of the swing screening shelf (20) so as to form a cleaning part (80).The cleaning part (80) is arranged to freely reciprocate along the length direction of the screen (23).In addition, the rim part (82a) of the scraper (82) inclines toward the movement direction of the scraper (82) and protrudes toward the left and right sides of the single plate (81). |
