step 3, adjusting the walking system (7), and controlling the regeneration depth through the lifting of the front supporting leg (71) and the rear supporting leg (72); adjusting the opening degree of a front charging door (413) and a rear charging door (414) of the working device (4), controlling a crushing and mixing space, and enabling a peripheral cutting edge of a milling rotor structure (42) to be located below a road surface for crushing and regenerating operation;
step 4, the hydraulic system drives the traveling system (7) to enable the whole machine to travel forwards to form a milling path; meanwhile, the side plate (412) of the working device (4) and the floating function of the rear blanking door are opened;
and 5, after the crushing and regeneration work is finished, performing watering maintenance after rolling by a road roller and leveling by a land leveler, and enabling 100% of the original road surface to be utilized into a water stabilizing layer on site.
