摘要

"IMPROVEMENTS INTRODUCED IN EXCAVATING MACHINES", characterized by the fact that in these machines and combined, active bodies of excavation are easily separable with respect to supporting structures that serve as means of support and coupling for the previous active organs, all this together with resilient, partially deformable, resilient organs arranged to join and connect, at will, each active excavating body with the supporting structure that corresponds to it when both elements are coupled together, with the particularity that the part of the active excavation body and the corresponding part of the supporting structure that supports it are substantially complementary and have, both parts, seats and surfaces of mutual contact that correspond substantially to portions of surfaces, revolution, distributors of stress transmitted from the mentioned active organs to the support structures that correspond to them, while each fastening element of the two coupled parts, has surfaces that are put in contact or in their case are locked, on the one hand, with the corresponding active body of excavation and, on the other hand, with its corresponding support structure for transmitting said internal stresses and selectively using, at least, an undulating and intermediate surface of mutual contact between the two separate but attachable parts that constitute each fastening element. , and both constituent parts of the clamping member are adapted to fit, under pressure and prior to their elastic partial deformation, into the corresponding housings provided in the area of mutual coupling between the excavation member and its corresponding support structure.
