<p>The invention realizes a cutting-mixing-feeding wagon (1) for forage and grass or straw silage comprising a container (2) in which there are one or more screw feeders (5) for the treatment of the material inserted in the container (2) itself through an opening (3). Each screw feeder (5) is provided with a couple of spirals (7, 8) axially opposed to one another and wound the one clockwise (7) and the other counterclockwise (8). Each end of each screw feeder (5) is provided with a scraping element (10) cooperating through a crawling with the external surface of a flange (9) put between the end of each screw feeder (5) and the wall (21) of said container (2). During the rotation of each screw feeder (5) said scraping element (10) prevents the material accumulation on the external surface of said flange (9) and on said wall (21) as well as in the area surrounding them.</p> |
