PROBLEM TO BE SOLVED: To provide a diffusion type snow injecting device capable of simply diffusion-adjusting injected snow in a desired diffusion range.SOLUTION: A diffusion type snow injecting device comprises: a body of revolution 110 with an upstream side end surface disposed in parallel with a downstream side end face of a snow feed pipe 40 for pressure-feeding snow particles with air current; and a revolution drive part for rotating the body of revolution 110 about its axial direction at a predetermined revolution speed, in which the body of revolution 110 includes a pressure-feed channel 114 inside which penetrates the body of revolution 110 in an axial direction; the pressure-feed channel 114 includes: an intake 118 on the upstream side end surface, the intake being disposed in a non-contact proximate opposite an outflow opening provided on the downstream side end face of the snow feed pipe 40; and a drain hole 122 on the downstream side end face, the drain hole 122 being positioned with respect to the intake 118 such that snow particles discharge so as to diffuse in an axial direction from the drain hole 122.SELECTED DRAWING: Figure 9 |
