DEVICE FOR DETECTING HEIGHT OF REAPING SECTION ABOVE GROUND FOR HARVESTER

Japanese Patent JP3828085

B2

PROBLEM TO BE SOLVED: To provide a device for detecting the height of a reaping section above the ground utilizing a ground contact sensor 21 in a scarcely breakable manner even if slipped sideways on the ground.
SOLUTION: The device has the following construction and mechanism: The ground contact sensor 21 is swingably supported axially X on a supporting body 25 mounted on a dividing frame 16. The supporting body 25 is linked to the dividing frame 16 so as to turn about the axis Y in the longitudinal direction of the machine body and impelled turnably by a coil spring 60 at a reference turning position where the ground contact sensor 21 is to make a vertical swinging motion about the axis X relative to the dividing frame 16. A detective unit 22 interlocks with the rotating support shaft 41 of the sensor 21 through an interlocking mechanism in a gear case 40 and functions to detect the height of the reaping section above the ground based on the swing angle of the sensor 21. The engagement part 65 of the dividing frame 16 is engaged on the engagement part 21d on the rear end of the sensor 21 so as to restrain the rear end of the sensor from slipping sideways relative to the dividing frame 16.
