发明名称 Snow thrower discharge chute blockage removing apparatus
摘要 An apparatus for safely dislodging accumulated snow and ice from the discharge chute of a rotary snow thrower, which includes a rigid plate adapted to be inserted in and removed from the discharge chute. The rigid plate is movably connected to an element of the snow thrower and is operatively connected to a handle. Rotation of the handle by the operator will selectively move the rigid plate within the discharge chute. The rigid plate will apply an axial force to the accumulated snow and ice, thereby dislodging the snow and ice without the plate coming into contact with the impeller.
