<P>PROBLEM TO BE SOLVED: To provide a harvester equipped with a separation part which is long life and excellent in energy saving property. <P>SOLUTION: The combine harvester has a separation part which separates a grain from a grain culm in a piloerection condition. A separation part includes: a separation part body which is constituted rotatably; a separating tooth 312 which separates the grain from the grain culm by rotating where the grain culm in the piloerection condition is contacted; and a separating tooth connecting part 313 arranged between the separating tooth 312 and the separation part body. Also when making a direction to which the separating tooth 312 projects, the protrusion direction, and making near the end part of the separation part body side among the separating teeth 312, a base end part 312a, a cross-sectional shape when cutting the base end part 312a with a face perpendicular to the protrusion, is bent to the opposite side at least at an end part, to the rotating direction of the separation part body. Also, in the cross-sectional shape when cutting the part where the separating tooth 312 is not connected among separating tooth connecting parts 313 with the face perpendicular to the rotary shaft of the separation part body, at least the end part of the protrusion direction side is bent to the side opposite to the rotating direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
