Abstract:
1. Earth moving bucket comprising a rigid chassis suspended on earth moving machinery, a main actuator housed in the chassis, two symmetrical jaws controlled by the main actuator and able to be displaced between positions of maximum opening and complete closure, each jaw being supported by two parallel suspension arms pivoting on the chassis around a common suspension spindle, these two spindles being in parallel with and spaced apart from each other on the chassis, each jaw being articulated, at the lower end of its suspension arms, on a pivoting spindle in parallel with the suspension spindles, and being connected to moving arms controlling tipping movements of the jaw on its pivoting spindle during opening or closing movement of the bucket, wherein each jaw is formed of two different rigid parts, namely a receptacle and a shovel, each having a base and a flange or a toothing arrangement, these two jaw parts being articulated to each other and to the suspension arms around said pivoting spindle and being further separately connected to the moving arms of the jaw, the shovel by direct articulation to its base, and the receptacle by connections between its base and the moving arms, the control of the jaws being effected by articulated systems with four push rods that connect the suspension and moving arms to the chassis and to the actuator and that are shaped and sized such that between the shovel and the receptacle of each jaw there is produced a relative pivoting movement on said pivoting spindle, of limited amplitude and in alternating directions during complete opening or closing movement of the bucket.
