- 摘要：
PROBLEM TO BE SOLVED: To provide a threshing section for a combine which can perform smooth threshing work with improved threshing performance achieved by making grain stalks less likely to tangle together into a rope-like shape.
SOLUTION: A threshing drum 31 of a threshing section 30 for a combine is provided with first threshing teeth 313 arranged at the intersection points between a first helix 301 and a second helix 302 which are coaxial with the threshing drum, wound in the same direction, and arranged at different helical pitches. The threshing drum is also provided with second threshing teeth arranged at positions which are adjacent in the front-rear direction to the first threshing teeth and are reached before or after the first helix, which has a smaller helical pitch than the second helix, completes substantial one revolution. The first threshing teeth and second threshing teeth are arranged such that only some of the first threshing teeth and only some of the second threshing teeth are overlapped on each other, in the front view. In a concave 32, tube-shaped, sieving body-forming pieces 322A of a sieving body 322 are mounted on a frame body 321.
