Abstract

See full text

An array of retractable shields is employed for closing an exposed opening through which the snow enters into a receiver. A piston-like object, which is empowered by a compressed spring and is moving at high speed, makes an impact on the snow with great force. The snow is finally ejected from a chute. The receiver can be lifted higher to clear the snow at a different height from the ground. Alternatively, a snow lifting unit is used to ferry the snow higher for free fall into the receiver for further processing. Belt and chain driven devices employing a plurality of collector elements are employed. An impact force produced by a rapid flow of compressed air also forces the snow out from a confined enclosure.
