The auger flight assembly may include a drive shaft rotatable about an axis and helical blades and helical pliable flights, wherein the helical blades and the helical pliable flights alternate with one another along an axial length of the drive shaft.
Claims9
A snow thrower comprising:
- an auger housing;
- and
- an auger flight assembly within the housing, the auger flight assembly comprising:
- consecutive helical auger flight blades comprising:
- a first helical auger flight blade helically extending about a rotational axis;
- a second helical auger flight blade helically extending about the rotational axis;
- and
- a helical pliable flight helically extending about the rotational axis between the first helical auger flight blade and the second helical auger flight blade, the helical pliable flight having an outer helical extremity radially beyond the first helical auger flight blade and the second helical auger flight blade, wherein the first helical auger flight blade and the second helical auger flight blade spiral 180° out of phase with respect to one another, the snow thrower further comprising:
- a second helical pliable flight helically extending about the rotational axis, wherein the helical pliable flight and the second helical pliable flight spiral 180° out of phase with respect to one another, wherein the helical pliable flight and the first helical auger flight blade spiral in phase with one another and wherein the second helical pliable flight and the second helical auger flight blade spiral in phase with one another.
