2. Specification
1 ) This invention relates to snow plowing device.
2) Most snow blowers available on the market are two-stage blowers. They use
steel
auger blades pitching snow up. Then, the high-speed impeller located directly
behind the auger blasts snow up and out of an adjustable discharge chute.
When the snow reaches the fan, the density of the snow is much higher than its
original states. This will increase the fan's workload.
Such snow blowers are popular in the market, since it is effective and well
designed. However, it is expensive for household use.
3) The novel design for this patient would be able to keep the snow at its
original
density. The snow was blasted up through air pressure generated by the high-
spinning fan, at one single stage. Since the snow at such state is fluffy, its
density
is low, the snow is easy to plow. The motor or engine used to power the fan is
the
same as the snow blowers mentioned at 2).

4) Figure I and Figure 2 shows the structure of this snow blower (Figure 1 & 2
attached).
(1) is the passive axle, with the fan attached (2). The passive axle goes
through
the back panel ( 12) and the bearing case ( 10). The axle connector ( 11 ) is
located
outside the housing. The motor or engine is connected to the connector,
driving
the snow blower.
The air current generated by the high-speed fan carries the snow through the
directional discharge chute (4) up into the air. (5) is the upper arch panel,
along
with the back panel, forming a half open-faced housing. The air drawn into the
housing from the front, accelerated by high-speed spinning fan, blows the snow
up through the discharge chute. (6) is the protection panel for safety
reasons. The
protection panel is tiled, other than the protection, it can also separate the
snow
into two layers, reduce the workload of the fan. (7) is the iron shoe. When
operating, the housing is slide on the ground, the iron shoes should be easily
replaced because of wear and tear. (8) is the snow scrapper. The left over
snow
will be swiped by the scrapper and blown away. (9) is the supporting frame. It
supports the back panel, the motor, or engine. The supporting frame has two
wheels and a handle.
A motor or engine can power the snow blower device. When connected to a
tractor that can provide the power, the snow blower can use two fans to
increase
the capacity (Figure 3).
5) Since the device is working through the strong air flow, it can also be
used for
outdoor dust cleaning, especially for collecting the leaves at fall.
