Claims

[Claims for Utility Model Registration] (1) When a cutting drum suspended on a self-propelled machine is driven to rotate, a drum angle changing means provided on the self-propelled machine determines the angle formed by the drum axis with respect to the traveling direction of the self-propelled machine. A road milling machine characterized by being able to be changed arbitrarily. (2) the cutting drum is suspended on the self-propelled machine body via a suspension bracket, one side of the suspension bracket is rotatably pivoted to the cutting drum suspension part of the self-propelled machine body by a fulcrum pin; The road milling machine according to claim 1, wherein the other side is connected to the cutting drum suspension section via a link mechanism. (3) The cutting drum is suspended on the self-propelled body via a suspension bracket, and a drum moving means is attached to the suspension bracket so as to be movable in the axial direction of the drum. Utility model registration claim 1, characterized in that the drum can be freely displaced in the axial direction.
The road milling machine described in section.
