| 摘要 |
The invention relates to a control mechanism of a scraper blade attachable under a vehicle, the mechanism comprising means for rotating the blade (6) in a horizontal plane, so that the lateral direction of the blade forms a specific angle with the driving direction, and means for tilting the blade (6) in a vertical plane parallel with the blade. Said means comprise a first mounting point (5) arranged to be movable in the horizontal plane for achieving said rotation of the blade. At this point the blade (6) is arranged to be movable, in a vertical plane parallel with the lateral direction of the blade for achieving said tilting motion of the blade. The means also comprise a second mounting point (7) which is arranged to be movable in a transverse plane relative to the lateral direction of the blade, preferably at the end of a swinging arm (8) articulated to the chassis (1), so that the motion of the second supporting point (7) brings about both tilting of the blade in the lateral direction and rotation of the blade relative to the driving direction. |
