Excavating assembly for milling a road surface or ground

A method for adjusting an excavating assembly, said method comprising:

• providing an excavating assembly for milling and/or scarifying a road surface or ground to be milled, wherein
• said excavating assembly comprises a support structure delimiting a compartment, said support structure comprising a compartment opening adapted to face said road surface or ground to be milled;
• said excavating assembly further comprises a cutter, said cutter being housed in said compartment of the support structure so as to be rotatable about a cutter axis and protruding from said compartment through said compartment opening to mill said road surface or ground to be milled;
• said excavating assembly further comprises a cutter movement unit connected to said cutter, said cutter movement unit being supported by said support structure;
• said excavating assembly further comprises at least one support element adapted to rest on said road surface or ground to be milled during milling operations, said at least one support element being separate from said support structure;
• wherein
• said cutter comprises a cutter axle extension protruding from said support structure thus extending said cutter axis;
• said at least one support element comprises an eccentric plate seat;
• said eccentric plate seat rotatably houses an eccentric plate so as to allow said eccentric plate to rotate about a support element axis;
• said eccentric plate comprises a cutter axle extension seat;
• said cutter axle extension seat houses said cutter axle extension so as to be freely rotatable;
• said cutter axis, as extended by said cutter axle extension, is eccentric with respect to said support element axis, defining a predetermined eccentricity;
• said excavating assembly further comprises an eccentric plate movement unit connected to said eccentric plate for moving said eccentric plate about said support element axis;
• and
• said support structure is oscillatingly connected to a connection element to allow said excavating assembly to oscillate about an axis of oscillation;
• and
• moving said eccentric plate in said eccentric plate seat so as to move eccentric arrangement of said cutter axis with respect to said support element axis thus displacing said predetermined eccentricity, increasing or decreasing the cutter portion protruding from the at least one support element, and modifying a cut depth when the excavating assembly is pressed against the road surface or ground to be milled.
