Abstract

Double forage cutting chain, which is essentially characterized in that the tool link is constituted by a prismatic piece of substantially square plant, with a central rectangular emptying, which presents coupling means, for the carrier plate of the blade, in one of its faces that have empty of material, while the other has three vertical projections, prismatic and parallel, one central and two lateral, whose projections have opposite holes, being in the lateral projections in which the ends of both are welded bolts that go through the connecting links, which are constituted by two parallel prismatic plates, the separation between their opposite faces being slightly smaller than the separation between the facing faces of two vertical projections closest to the tool-holder link, each plate being of rectangular shape with its smaller rounded faces and with recesses in the center of their larger side faces, both plates being joined by two sockets in which the bolts are housed, acting as articulation axes between two connecting links and one tool holder, in which they have at least one link of splicing, constituted by two bushes in axial position, with their corresponding prismatic plates, the two closest to each bushing, joined by welding to a complementary piece arranged cantilevered on one of its ends, also presenting two other complementary pieces welded on the outer faces of the plates of each bushing, arranging the three complementary pieces of opposite holes for the passage of a pin, which is also housed in the bushes of two connecting links, the removable fixing being carried out with the interposition of a washer and a pin, also being characterized because the pieces are made each in a sun to molding operation.
