<P>PROBLEM TO BE SOLVED: To provide a reaping height detector and a reaping height controller for a combine harvester in which the reaping height detector is disposed in a relatively narrower space so that the detector may not be damaged by an external force acting on a grounding body in front/back and left/right directions while following the front-back and left-right motions of a reaping part. <P>SOLUTION: In the reaping height detector, a first supporting shaft (1) is horizontally disposed to the lower part of a grass dividing body (42) provided to a reaping device (27); a first supporting body (2) is vertically-slidably and rotatably attached to the first supporting shaft (1); a second supporting body (4) is rotatably attached to the second supporting shaft (3) disposed to the rear side part of the first supporting body (2) in directions on the front and back ; the base part of a grounding body (6) extending obliquely downward and backward is attached to the third supporting shaft (5) attached to the second supporting body (4) in directions on the right and left; and an angle sensor (10) for detecting the angle of the rotation of the third supporting shaft (5) due to the vertical shaking of the grounding body (6) is disposed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
