Pavement milling mechanism of self-driven civil engineering machine

The invention discloses a pavement milling mechanism of a self-driven civil engineering machine, and relates to the technical field of pavement milling. One end of the telescopic rod is hinged to one side of the driving vehicle; one end of the connecting rod is hinged to the driving vehicle, and the other end of the telescopic rod is hinged to the position, close to the driving vehicle, of the connecting rod; the number of the mounting plates is two, and the mounting plates are symmetrically hinged to the driving vehicle; the grinding and milling assembly is rotationally arranged between the mounting plates and is driven by a grinding and milling motor fixed on the mounting plates; and the adjusting assembly is rotationally arranged in the position, away from the milling motor, of the mounting plate, and the adjusting assembly and the milling assembly are coaxially arranged. The grinding and milling assembly can be quickly replaced and adjusted through the adjusting assembly, so that the road surface is groun
