ABSTRACT:
A truck for shredding and mixing products for zootechnical use, of the type that comprises, on a chassis (11) with wheels (12) that is self-propelled or towed, a container (13) that is substantially shaped like an inverted frustum, is open in an upper region and contains shredding and mixing means (14) which comprise at least two adjacent rotating main screw feeders (15, 16), each having an external profile (17) that lies on a substantially conical imaginary surface and at which shredding cutters are mounted. Contrast cutters (20) substantially shaped like circular sectors are hinged to the internal wall of the container (13) by means of their respective vertices in a vertical arrangement in substantially radial positions and can be inserted and removed through appropriately provided slots. Auxiliary screw feeders (18, 19), suitable to avoid the formation of stagnation regions, are arranged between the main screw feeders (15, 16), in the regions adjacent to the walls of the container (13).
