US Patent 11753785 Snow plough

A snow plough includes 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. The auger includes a snow-collecting blade located at least on one side in a width direction of the auger, the snow-collecting blade collecting snow toward a center of the auger in the width direction, and a snow-throwing blade located at the center of the auger in the width direction, the snow-throwing unit casting snow collected by the snow-collecting blade by a centrifugal force and discharging snow to an outside via a chute. The snow-throwing blade includes an outer circumferential snow-throwing plate rotating along an outer circumferential region positioned outside an inner circumferential region, the inner circumferential region being a non-snow-throwing region within the auger housing.
