<p>A truck for shredding and mixing products for zootechnical use, comprising, on a self-propelled or towed wheeled chassis, a frustum-shaped container that tapers downwardly, is open at the top, and contains a scroll that rotates with a vertical axis and has an external profile that lies on a substantially conical ideal surface, shredding cutters being fitted at the profile. Countercutters (18), shaped substantially like a circular sector, are pivoted in a vertical arrangement, by means of their respective vertices, to the wall of the container in substantially radial positions and can be inserted and extracted through specifically provided slots. The truck furthermore comprises an automatic actuation and control device (21) for the positioning of the countercutters (18) according to work variables. The actuation and control device (21) is constituted by an electronic control unit (33) that controls means (22) for the movement of the countercutters (18). <IMAGE></p> |
