1. A snow plough comprising:
a driving source;
an auger housing;
a rotating shaft to be driven and rotated by the driving source within the auger housing; and
an auger arranged within the auger housing and to be driven and rotated via the rotating shaft,
wherein the auger includes:
a snow-collecting unit located at least on one side in a width direction of the auger, the snow-collecting unit collecting snow toward a center of the auger in the width direction; and
a snow-throwing unit located at the center of the auger in the width direction, the snow-throwing unit casting snow collected by the snow-collecting unit by a centrifugal force and discharging snow to an outside via a chute, and
wherein the snow-throwing unit includes
a rotating plate attached to the rotating shaft and a snow-throwing plate attached on an outer circumferential side of the rotating plate,
the rotating plate includes an inner circumferential rotating plate and support plates, the inner circumferential rotating plate is plate-shaped and extends in an axial direction of the rotating shaft, the support plates extend in a direction generally orthogonal to the rotating shaft from both end portions in an extending direction of the inner circumferential rotating plate,
the snow-throwing plate is attached to tip end portions of the support plates,
the snow-throwing plate includes an outer circumferential snow-throwing plate and side wall plates, the outer circumferential snow-throwing plate is plate-shaped and extends in the axial direction of the rotating shaft and is spaced from the inner circumferential rotating plate, the side wall plates extend in the direction generally orthogonal to the rotating shaft from both end portions in the extending direction of the outer circumferential snow-throwing plate and are positioned inside each of the support plates,
a plate surface of the outer circumferential snow-throwing plate is inclined at a prescribed angle with respect to a plate surface of the inner circumferential rotating plate, and
the inner circumferential rotating plate rotates along inner circumferential region positioned inside an outer circumferential region, the inner circumferential region being a non-snow-throwing region within the auger housing, and the outer circumferential snow-throwing plate rotates along the outer circumferential region positioned outside the non-snow-throwing region.
