A constant-rate, force-feed artificial snow making machine which is an air blowing crusher for eliminating variations in ice lump supply amount to eliminate variations in ice-snow particle size and ice-snow stuck in a casing and for effectively using blown air to discharge ice-snow to distant locations as artificial snow, the snow making machine comprising; a constant-rate ice lump supply machine (1) having a casing (3) provided in the upper portion thereof with an ice lump inlet (4) for receiving ice lumps (2), rotary vanes (8) rotating within the casing (3) to supply ice lumps (2) at a constant rate, and ice lump outlet (5) provided in the lower portion of the casing (3); and an air blowing crusher (11) having a casing (13) provided in a side surface thereof with an air blowing tube inlet (10) of an air blowing tube (9) for receiving ice lumps (2) supplied from the ice lump supply machine (1) along with blown air (12), rotary vanes (15) provided within the casing (13) and for crushing ice lumps (2) into ice-snow (18), and a blown air exhaust port (19) provided in a side surface opposite to the air blowing tube inlet (10) of the casing (13) and for discharging the obtained ice-snow (18) as artificial snow (20); characterized in that an ice lump receiving port (14) of the crusher (11) is continuously provided to the ice lump outlet (5) of the ice lump supply machine (1) via the air blowing tube (9).

L'invention porte sur une machine à neige artificielle à débit constant et alimentation forcée muni d'un broyeur pneumatique régularisant le débit d'alimentation en morceaux de glace, réduisant les variations de taille des particules de glace/neige et leur accumulation dans le carter, et utilisant efficacement de l'air comprimé pour transporter les particules de glace/neige en des points éloignés. Ladite machine comporte: un dispositif (1) d'alimentation en morceaux de glace à débit constant consistant en une enceinte (3) présentant un orifice (4) supérieur d'introduction des morceaux de glace (2), un rotor à palettes (8) tournant dans l'enceinte et propulsant les morceaux de glace à débit constant, et un orifice (5) inférieur de sortie; et un broyeur pneumatique (11) dont le carter (13), qui présente d'un côté un orifice (10) et un conduit (9) d'insufflage d'air et reçoit à la fois les morceaux de glace venant du dispositif (1) d'alimentation et l'air (12) insufflé, est muni d'un rotor à palettes (15) tournant dans le carter et broyant les morceaux de glace (2) en particules de glace/neige (18) et d'un orifice (19) d'éjection d'air et de particules (2) de neige artificielle (20) disposé sur le carter à l'opposé de l'orifice (10) d'insufflage. Ladite machine se caractérise en ce que l'orifice (14) d'alimentation du broyeur en morceaux de glace est relié en continu à l'orifice (5) de sortie du dispositif (1) d'alimentation via le tube d'insufflage (9).
