PCT No. PCT/EP96/00934 Sec. 371 Date Jun. 16, 1998 Sec. 102(e) Date Jun. 16, 1998 PCT Filed Mar. 6, 1996 PCT Pub. No. WO97/17840 PCT Pub. Date May 22, 1997The invention is a cutter-mixer-feeder wagon for fodder and grass or straw silage, comprising at least two rotary screw feeders (7), housed inside a compartment (75) with curved section obtained on the bottom (76) of the container (2) itself, each one provided with at least one pair of spirals (9, 10), on which peripheral cutters (13) are fixed, one of said spirals being wound clockwise (10) and the other anticlockwise (9), starting from the ends of the screw feeder and such as to convey the processed material towards the area where said right and left spirals converge. Each one of said spirals (9, 10) is provided, on its end facing the other spiral, with two or more discharge openings obtained on its profile (91, 92, 93; 101, 102, 103), each one of said openings being carried out by removing a portion of the spiral, where each discharge opening is formed by a substantially radial segment and by an arc-shaped part that are substantially orthogonal to each other, while said right and left spirals are interrupted at about 180 DEG from each other, until they touch an ideal plane that intersects the longitudinal axis of the screw feeders.
