Milling mechanism and engineering vehicle thereof

The invention discloses a milling mechanism and an engineering vehicle thereof, and belongs to the technical field of engineering machinery. The defects that in the prior art, a traditional milling machine is low in operation and transition speed, long-distance transition is inconvenient, and the traditional milling machine is not suitable for developing a primary hard soil road are overcome by the milling mechanism and the engineering vehicle thereof. A main structure of the milling mechanism comprises a traction frame, a rotary frame and a locking mechanism are arranged on the traction frame, a milling drum is arranged on the rotary frame, one side of the milling drum is connected with one side of the rotary frame through a driving device and an angle oil cylinder, and the other side ofthe milling drum is connected with the other side of the rotary frame through a travelling support and an angle oil cylinder. The milling mechanism and the engineering vehicle thereof are mainly usedfor opening up primary har
