Blowing unit null of snow throwing die

摘要

PURPOSE:To promote snow-throwing efficiency by making the internal circumferential surface of a blower casing of a shape with convex curvature on the outside thereof and making the maximum inside diameter of the internal circumferential surface larger than that of a connecting port of an auger housing and the blower casing. CONSTITUTION:A blower casing 8 in which a blower 7 is provided is made of a shape with convex curvature on the outside of the internal circumferential surface of the blower casing. The maximum inside diameter of the internal circumferential surface of the blower casing 8 should be larger than that of a connecting port 6 connecting an auger housing 5 and the blower casing 8. Accordingly, the snow taken into the blower 7 is collected in the part of the maximum inside diameter of the blower casing 8, so that the snow-throwing efficiency can be promoted.
