1. An apparatus for use with an excavator for separating liquid from a liquid-solid mixture, the apparatus comprising:
an excavator bucket having a plurality of openings between the bucket interior and the bucket exterior, the openings configured to permit passage of liquid and impede passage of solids; and a pressure pad movable by a user relative to the bucket between an open position in which material may be received into, and removed from, the bucket interior, and a compressing position in which the pressure pad intrudes into the bucket interior, whereby liquid may be separated from a liquid-solid mixture located within the bucket interior, by moving the pressure pad toward the compressing position so as to compress liquid-solid mixture thereby causing liquid to flow through the openings wherein,
the apparatus further comprises:
a hydraulic rotary actuator mounted to the excavator bucket, controllable by the user and having an axis of rotation; andone or more pressure pad arms interposed between the hydraulic rotary actuator and the pressure pad, whereby the pressure pad is hingedly connected to the excavator bucket and is movable by the user in an arc about the axis of rotation of the rotary actuator;the bucket interior includes two opposed side surfaces, an upper surface and a lower surface, each of the upper surface and lower surface curved concentric with the axis of rotation of the rotary actuator:a gasket is affixed to the pressure pad and in use, the gasket abuts the side surfaces, upper surface and lower surface of the bucket interior through a range of movement in the arc about the axis of rotation of the rotary actuator. |
