摘要
The device for stabilizing a baricentric suspended bar, in particular a plant protection spraying frame, according to the invention, ensures good stabilization during the operation of the sprinkler frame, the beams and other elements of the plant protection devices . For this purpose, a bearing mounted shaft and a spraying frame are joined together by a spherical joint that takes over the moment of rotation. For the purpose of transmitting forces, an appropriate form of execution is where the point of rotation of the spherical joint is at the center of gravity of the spraying frame, for balancing the particularly dangerous vertical forces acting on the spraying frame, a form of execution being where a lever arm limiting the moments, which turns a twist into an axial displacement, is mounted in the center and the two ends of which are supported by rollers on some forced trajectories. The forced trajectories are located on the frame, and in order to attenuate the damaging effect of the dynamic transmission of forces, there is provided a form of execution in which the spherical joint is connected to the spraying center by a hub, to which, on the one hand, the hub is supported by a disk mounted with the possibility of its axial displacement on the axle, on an elastic element preferably mounted at the center of gravity of the spraying frame between the disc and the frame, suitably on a rubber annular block, and on the other hand, the needle is mounted in the frame with the possibility of its displacement.
