<p>The invention relates to a mechanism for rotating the rear implements in mobile equipments for agricultural and animal breeding works, road constructions and maintenance, as well as for mechanizing works in other fields. According to the invention, the mechanism comprises a swinging support (1) which is detachably fixed on a rear structure (2) of the implement and a swinging base (3), the connection therebetween being ensured by two hydraulic rotation cylinders (4) which, by means of some fixing eyes (5), are fixed to the rear structure(2), at one end, and to the swinging base (3), at the other end, said double-effect rotation cylinders (4) having the role of driving into rotation the swinging base (3) when supplied with hydraulic pressure and determining, by the hydraulic control circuit, a synchronous antagonic operation, on the swinging base (3) there being fixed the arm of the rear implement on which the working tools are fixed by means of the arm fixing bolt (5'), and articulated with the arm lifting cylinder by means of an articulation support (6) mounted on the swinging base (3), the driving cylinders (4) acting upon the swinging base (3) simultaneously and in opposite directions, thereby creating the rotation torque of the swinging base (3), with the possibility of achieving a rotation angle of the rear structure (2) and the implement of up to 270°, as well as the safety and control of the rotation.</p> |
