Snow directing and discharging assembly
A snow thrower may include an auger housing; and an auger flight assembly. 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.
1. 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.
2. The snow thrower of claim 1 , wherein the helical pliable flight comprises multiple rows of bristles helically extending in parallel about the rotational axis.
3. The snow thrower of claim 2 , wherein the multiple rows diverge outwardly away from one another such that the helical pliable flight has a V-shape.
4. The snow thrower of claim 1 , wherein the first helical auger flight blade and the second helical auger flight blade have outer extremities within the auger housing and wherein the outer helical extremity is beyond the auger housing.
5. The snow thrower of claim 1 , wherein the outer helical extremity extends at least ½ inch beyond the first helical auger flight blade and the second helical auger flight blade.
6. The snow thrower of claim 1 , wherein the first helical auger flight blade has a first radial length and wherein the helical pliable flight comprises bristles, each of the bristles has a second radial length greater than the first radial length.
7. The snow thrower of claim 1 further comprising:
a hub; and
supports, each support having a first end coupled to the hub and second ends supporting and spacing an inner helical edge of each of the first helical auger flight blade, the second helical auger flight blade and the helical pliable flight from the hub.
8. The snow thrower of claim 1 , wherein the helical pliable flight comprises flexible belting.
9. The snow thrower of claim 1 , wherein the helical pliable flight comprises a spiral backing holding first and second rows of bristles in place, wherein each of the first and second rows of bristles begin diverging at the backing.
