PROBLEM TO BE SOLVED: To improve performance for uptaking cereal stems by enhancing pulling action of the cereal stems to an axial flow threshing cylinder, reduce an axial load of the threshing drum and improve threshing efficiency. SOLUTION: In a combine in which the axial flow threshing drum is installed in almost perpendicular direction to the direction in which cereal stems are fed through a feed port and threshing is carried out by moving the cereal stems in the shaft direction from the starting end to the last end of the axial flow threshing cylinder, wire-threshing teeth are installed to be protruding to the peripheral surface of the end of the axial flow threshing drum locating in the side of the feed port, while a dust feed valve is installed above the starting end and spiral conveyer are installed to be protruding on the balanced peripheral surface of the axial flow threshing cylinder.
