Snow blower with an adjustable back

Abstract

A snow blower including an adjustable back that allows to blow snow in a forward direction or backwards. The adjustable back is actuated by a cylinder or a hydraulic motor that makes rotate the back in a forward or backward direction of a bidirectional auger rotating clockwise for clearing snow collecting in its opening until snow is intercepted by the bidirectional auger and directed on an arrangement of impellers arranged on the bidirectional auger propelling snow toward the rotating ejection pallets until snow is directed toward a discharge chute. And when the snow level is high a movable cover secured to the structure of the snow blower is lifted by a cylinder to let snow fall on the bidirectional auger and to be directed on the arrangement of the impellers propelling snow toward the rotating ejection pallets until snow is directed toward the discharge chute.

I claim: 
     
         1 . A snow blower that is attached to a vehicle, said snow blower comprises an adjustable back allowing to blow snow in a forward direction or backwards, said adjustable back is actuated by a cylinder or a hydraulic motor that makes rotate the back in a forward or backward direction of a bidirectional auger rotating clockwise for clearing snow collecting in its opening until snow is intercepted by the bidirectional auger and to be directed on an arrangement of impellers arranged on said bidirectional auger propelling snow toward the rotating ejection pallets it until snow is directed toward a discharge chute that is actuated by a cylinder and oriented in the desired direction by a motor. 
     
     
         2 . A snow blower according to  claim 1 , characterized in that when the operator moves and blows snow in a forward direction with the vehicle to which is attached the snow blower, the adjustable back is to be the back wall of the snow blower for clearing snow collecting in its front opening until snow is intercepted by the bidirectional auger and to be directed on the arrangement of impellers arranged on said bidirectional auger propelling snow toward the it rotating ejection pallets until snow is directed toward the discharge chute. 
     
     
         3 . A snow blower according to  claim 1 , characterized in that when the operator moves and blows snow backwards with the vehicle to which is attached to the snow blower, the adjustable back is to be the front wall of the snow blower for clearing snow collecting in its opening that is located rearwardly until snow is intercepted by the bidirectional auger and to be directed on the arrangement of the impellers arranged on said bidirectional auger propelling snow toward the rotating ejection pallets until snow is directed toward the discharge chute. 
     
     
         4 . A snow blower according to  claim 1 , characterized in that when the snow level is high a movable cover secured to a structure of the snow blower is lifted by a cylinder to let snow fall on the bidirectional auger and to be directed on the arrangement of the impellers propelling snow toward the rotating ejection pallets until snow is directed toward the discharge chute.
