Snow-plowing apparatus

A snow-plowing apparatus comprising a construction in which:

• a snowplow rotating member, having a water wheel type rotating body, disposed on a central position and provided with plural plate blades with a predetermined pitch in a peripheral direction, and screw type rotating bodies, which are disposed as to neighbor the water wheel type rotating body on left side and right side and provided with screw blades forming mutually opposite spiral configurations, and having inner disc portions, is provided;
• a shaft member, penetrating the rotating member to drive the rotating member to rotate around a horizontal axis, is provided;
• a housing member, disposed to surround a near portion of the rotating member on a rear side and having a snow-shooting wall portion, which covers the whole width of the rotating member, is provided;
• and
• the screw type rotating bodies plow snow in the horizontal axis direction and transfer the snow to the central position through a gap between the screw blades of the screw type rotating bodies and the snow-shooting wall portion of the housing member, and the snow gathered on the central position is plowed upward by the water wheel type rotating body,
• wherein a pair of disc portions is disposed parallel on left and right side end portions of the water wheel type rotating body and attached to respective inner wall portions of the inner disk portions of the screw type rotating bodies;
• the plural plate blades are fixed to a peripheral face of a cylindrical connecting portion which connects the plural plate blades with inner faces of the disc portions;
• and
• each plate blade is inclining forward with an inclination angle of 30° to 50° in the peripheral direction;
• and openings are formed in the disc portions of the water wheel type rotating body and the inner disc portions of the screw type rotating bodies and arranged such that snow is sent through the openings from the screw type rotating bodies to the water wheel type rotating body.
