Blade support structure of bulldozer |
摘要 |
In a blade support structure of a bulldozer, a rotational axis of an angle control can be formed as a rotational axis which is always directed to one vertical direction, without reference to a pitch control of a blade. A pitching joint is arranged in a front end portion of a pitch support link having a fixed length, an eccentric disc is engaged with a pitching shaft, and the eccentric disc is fitted to a fitting hole formed in a bracket arranged in a back surface of the blade. A rotational axis at a time of an angle control which is constituted by a rotational center of a universal joint rotatably supporting the blade back surface and by a rotational center of the pitching joint is formed on a vertical line with respect to the ground surface.
