ける自動高低調節装置。 The lower end of the front link, which forms one side of a parallelogram, is rotatably pivoted to the front part of the upper surface of the backbone beam on which the gauge wheel and scratching claw are attached, forming an axis point A, and from the axis point A. Also, an axis point B is formed at the rear and at a high position on the sub-beam on the backbone beam, and the lower end of the rear link, which has the same length as the front link and corresponds to the front link, is rotatably pivoted. In addition, the channel beam to be attached to the main frame is installed and fixed so that there is an upper diagonal line F parallel to the lower diagonal line E of the front and rear heights connecting the axis points A and B, and the upper diagonal line The upper end of the front link is rotatably pivoted with the lower end of F as an axis point C, and the upper end of the rear link is also rotatably pivoted to the rear upper end of the upper diagonal line F to form an axis point D. Further, the lower end of the arc-shaped guide rod surrounding the compression spring is pivotally connected to the axis point A, and the upper part of the pivot point is slidably engaged with the channel beam, and An automatic height adjustment device for a cultivator, characterized in that the upper end of a surrounding compression spring is locked.
