Snow-plowing apparatus

Abstract

A snow-plowing apparatus constructed as that a snowplow rotating member having a water wheel type rotating body placed on a central position and screw type rotating bodies each of which is placed respectively as to neighbor the water wheel type rotating body on the left side and the right side, is provided, the rotating member is rotated around a horizontal axis and having a housing member set as to surround near a rear portion of the rotating member, the snow is plowed in the direction of the horizontal axis and moved to the central position by the screw type rotating bodies, and the snow gathered on the central position is shot upward by the water wheel type rotating body.

         2 . 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.

         4 . The snow-plowing apparatus as set forth in  claim 2 , wherein the shaft member has a polygonal cross sectional configuration, an insertion hole portion of polygonal configuration to which the shaft member is inserted is formed through each of the water wheel type rotating body and the screw type rotating bodies, and the shaft member is detachably inserted to the insertion hole portions.
