MILLING ROTOR

The invention provides a milling rotor, and the milling rotor includes a drum having a cylindrical wall disposed about a central axis of the drum. The milling rotor also includes a series of milling bit assemblies arranged in a spiral pattern on an outer surface of the cylindrical wall. The series of milling bit assemblies is configured to commence from a lateral plane that is transverse to the central axis of the drum and located partway along a length of the cylindrical wall. The series of milling bit assemblies is also configured to terminate proximate an end of the cylindrical wall. Each milling bit assembly is positioned such that an angle subtended by the series of milling bit assemblies with the lateral plane increases with increasing distance from the end of the cylindrical wall. 本发明提供了一种铣削转子，其包括滚筒，所述滚筒具有围绕所述滚筒的中心轴线设置的圆柱形壁。所述铣削转子还包括铣削钻头组件系列，所述铣削钻头组件系列以螺旋图案布置在所述圆柱形壁的外表面上。所述铣削钻头组件系列被构造成从侧向平面开始，所述侧向平面横向于所述滚筒的中心轴线并且定位在沿着所述圆柱形壁的长度的中途。所述铣削钻头组件系列还被构造成邻近所述圆柱形壁的端部终止。每个铣削钻头组件被定位成使得由所述铣削钻头组件系列与所述侧向平面所夹的角随着与所述圆柱形
