COMBINE

摘要

PURPOSE: A combine including a wedge-shaped intervening space is provided to treat cereals with care with a surface threshing grain and a wall of the transfer channel forming a wedge shape, and to steadily thresh grains. CONSTITUTION: A combine comprises the following: a transfer channel(22); a worm conveyor apparatus including a worm(23) extended inside the transfer channel to rotate; a wedge-shaped intervening space(27) widening to the transfer direction of the worm with a surface of the worm threshing grains(26) and a wall of the transfer channel(25); and an edge(28) in an acute angle facing the wall of the transfer channel included in the surface of the worm. The surface of the worm threshing grains is formed in a spiral formed outside edge of the worm or located at the intervening space between the two helix lines of the worm.
