<p>The rotary plough stone protection device has a share fixed to a T-shaped bar and can pivot about a joint. The bar has a buffer store supported on the bar and on a tension bar, which acts on the plough frame and on the store. The rear end of the tension bar (17) engages on an arm (29) of an angle lever (20) which can turn freely about an axis (27) on the main bar (1). On the other arm (22) is a couple (21), whose other end is hinged to a lever (23) which can also pivot about an axis on the main bar (1). The two axes (27,28), the angle lever (20) and lever (23) are so rated and arranged that in the couple joint (24), the couple (21) executes a linear motion on deflecting the share (7).</p> |
