Abstract
A snowblower for use particularly with wet and heavy snow formed by a precutting device (8) which rotates about the axis of a blower wheel (4) and is situated in front of the blower wheel in the snow clearing direction. Also included are worm gears (2,3) which rotate about vertical axes and are disposed on both sides in front of the blower wheel (4). The precutting device (8) has radial cutting arms (9) with radii corresponding to the radius of the blower wheel (4). The rotational bodies formed by the precutting device and the worm gears interact with one another without contact.
Claims6
A snowblower comprising
- a blower wheel (4) with a horizontal rotational axis running in the direction in which snow is being cleared;
- a precutting device (8) which rotates about the same rotational axis and is disposed in front of the blower wheel in the snow clearing direction;
- and
- snow-clearing worm gears (2,3) which rotate about vertical axes and are disposed on both sides in front of the blower wheel;
- characterized in that
- the precutting device (8) has radial cutting arms (9) each with a radius corresponding approximately to the radius of the blower wheel (4);
- and
- the rotational bodies formed by the precutting device (8) and the worm gears (2, 3) are tailored to one another, at least as seen from the top, so that the respective rotating parts interact with one another without contact.
