Abstract

Damping device for tillage bars, being usable in plows where a plurality of bars are mounted, and having as purpose to allow the tilting of each and every one of them before their possible encounter with an obstacle in the normal plowing process, eliminating the possibility of damage to them due to overexertion caused by the pull of the tractor vehicle, essentially characterized in that each grille is associated with a swing arm that is connected through a pin or any other conventional hinge system to the corresponding bushing sliding on the crosspiece of the frame of the plow, so that said swinging arm adopts, under normal working conditions, a backward and downward inclination, which is maintained by the tension of two robust springs that relate the middle area of said arm with a flat bar which is vertical and descending projection of the corresponding cap, leaving such spring s included in a horizontal horizontal plane and configuring said springs, together with said plate and with the swinging arm, a deformable triangle that before the incidence of the grid on an immovable obstacle, allows the tilting of said arm and the movement of the grid with with respect to the frame according to a trajectory in an arc of circumference, which ensures its release with respect to the obstacle.
