ABSTRACT:
In a rotary snow plow, especially one with a high plowing capacity, with two driven feeding mechanisms (7), which are disposed on either side of the centrifugal wheel (2) and, in the direction of plowing (F), ahead of the centrifugal wheel housing (1), and which rotate in opposite directions about vertical axes and the outside of which in each case is covered totally or partly by a flashing (8), which surrounds the feeding mechanism (7) tightly, the feeding mechanism (7), for the purpose of increasing the plowing performance while using energy sparingly, comprises essentially a cage-like rotor with throwing blades (4) disposed along surface lines and distributed over the circumference, the throwing blades (14), which rotate about vertical axes, also being driven and moreover in a direction opposite to the respective rotation of the feeding mechanism (7).
