WORKING MEMBER OF ROTOR SNOW PLOUGH Russian patent published in 1997 - IPC

FIELD: municipal engineering. SUBSTANCE: working member of rotor snow plough has housing with charging port. Housing accommodates feeder made in form of augers with opposite hand-of-helix screw blades with teeth on cutting edge, divider secured in middle part of feeder, two cutting ring disks with teeth arranged before charging port, blades secured on ring disks at side of augers and divider placed between disks. Blades are secured between inner and outer generating surfaces of disk ring at angle to disk radius. Each second tooth of auger blades is bent through acute angle relative to blade surface in direction of snow mass movement along feeder. Teeth of ring disks are bent alternately in different sides through acute angles relative to disk planes. Divider is made in form of fixed hexagonal pyramid with vertex pointed in direction of movement of working member and limited by inner generatrix of disk ring. Vertex of divider pyramid is pointed at angle relative to road bed surface, and vertical axis of divider pyramid base exceeds its horizontal axis. EFFECT: improved quality of rod cleaning. 6 cl, 7 dwg
