<p>A hopper (32) has a flat bottom (42) ending in a bight (44) aligned with a lateral outlet (34). A slide (52) provided with a pusher scoop (56) is slidable along the flat bottom transversely to the semicircular bight and is driven by hydraulic actuators (54). A feeding piston (46) is movable along the semicircular bight toward said outlet, the piston being driven by a hydraulic actuator (48). <IMAGE></p> |
