Auxiliary drill for excavator that has cutting heads and a milling chain

摘要

Auxiliary drill for excavator, with an attached console (02), for mounting on a mobile arm supporting an excavator, with at least one motor (11) and two cross-cutting heads (03) rotatably driven by that, which are installed on both sides of the longitudinal axis of the console (02) attached and have numerous milling blades (04), describing the milling blades (04) of each cross-cutting head (03), in its rotation, a cylindrical lateral surface of milling, characterized in that it is also provided a chain (01) circulating milling machine with numerous milling blades (04) whose direction of travel runs parallel to the longitudinal axis of the console (02) attached and thus extending between the two heads (03) cross section; because an anterior line of inversion, of the milling chain (01), is essentially located in a plane tangent to the lateral milling surfaces of the two cross-cutting heads (03); and because the motor (11) that drives the cross-cutting heads (03) also drives the milling chain (01).
