  • Patent number: 12043970
    Abstract: A snow removal machine is provided which may prevent ejection of snow collected by a snow-collecting unit to an outside and may perform efficient snow removal. A snow removal machine 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 snow-collecting blades located on both sides in a width direction of the auger and 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, casting snow collected by the snow-collecting blades by a centrifugal force, and discharging snow to an outside via a chute, and the snow-collecting. blades are rotated at a lower speed than the snow-throwing blade.
