Title (EN) THREE-STAGE SNOW THROWER
(FR) SOUFFLEUSE À NEIGE À TROIS ÉTAGES
Abstract:
(EN) A three-stage snow thrower having a housing, a power supply, a longitudinal drive shaft extending from the power supply into the housing, and a lateral drive shaft extending between opposing side walls of the housing and being meshingly engaged with the longitudinal drive shaft within a gear assembly. The first stage assembly includes a plurality of augers attached to the lateral drive shaft for pushing loosened snow axially toward the gear assembly. The second stage assembly includes at least one auger attached to the longitudinal drive shaft for pushing snow from the first stage assembly axially rearward. The third stage assembly includes an impeller that rotates to throw the snow through a chute attached to the housing to expel the snow from the housing.
(FR) Cette invention concerne une souffleuse à neige à trois étages, comprenant un boîtier, un bloc d'alimentation, un arbre d'entraînement longitudinal s'étendant à partir du bloc d'alimentation vers l'intérieur du boîtier, et un arbre d'entraînement latéral s'étendant entre des parois latérales opposées du boîtier et engrené avec l'arbre d'entraînement longitudinal au sein d'un ensemble engrenage. L'ensemble formant premier étage comprend une pluralité de tarières fixées à l'arbre d'entraînement latéral pour pousser la neige ameublie dans un sens axial vers l'ensemble engrenage. L'ensemble formant deuxième étage comprend au moins une tarière fixée à l'arbre d'entraînement longitudinal pour pousser vers l'arrière la neige provenant de l'ensemble formant premier étage. L'ensemble formant troisième étage comprend une turbine qui tourne dans le but de projeter la neige par l'intermédiaire d'un conduit d'éjection fixé au boîtier afin d'expulser la neige du boîtier.
