摘要： PURPOSE:To simplify the structure and improve the accuracy of grading by covering the whole periphery of a threshing cylinder with a concave screen, setting a suction type waste discharging fan at the side part of a culm discharge chamber 12 and arranging the end part of the second receiving gutter under a shaking separation shelf and the end part of the threshing cylinder in the same length in the longitudinal back-and-forth direction. CONSTITUTION:The whole periphery of a threshing cylinder is covered with a concave screen 9 and a suction type dust discharging fan 13 is set at the side part of a culm discharge chamber 12. The end part of the second receiving gutter 26 and the end part of the threshing cylinder are cut short to an even length in the back-and-forth direction. When coming to the above of the second receiving gutter, waste straws are discharged out of the machine body by a compressed-air fan 23 and the suction type dust discharging fan and can be prevented from dropping onto the second receiving gutter. A straw rack above the second gutter can, therefore, be omitted.
