Hand snowplow

types of manual snowthrower

All machines for manual snow removal have the same principle of action - first a capture of the snow mass, and then through the chute it is ejected outward from the surface of the clearing.

There aggregates such types:

• Single Stage (Screw) - both processes are carried out by a rotary motion of the screw mechanism
• two-stage (shnekovo rotary) - Snow is captured through a screw mechanism, and garbage - using blades special throws impeller throughtrough is due to the rotor.

rotary-screw device

Augers hand units are the traditional form of screws, the edge of the working surface can be either smooth or toothed.Smooth edges are used for cleaning soft snow layer of low density and relief - for the icy crusts and matted.

impellers on the rotor-stator shnekovo snowthrower are typically 3 to 6 the blades, which, depending on the load, are made of plastic or metal.

To prevent failure of any part of the unit because of the falling objects and large particles auger and impeller attached to the shaft of the shear bolts or pins, which allows them to break with the sudden stop of a part.As a rule, it will help protect electric motors and other components, and replace bolts not be easy.

Design features

Dimensions snegozagrebnogo bucket which surrounds the screw, determines the amount of snow cover, clears the machine.Accordingly, with an increase in the size of the bucket will increase the performance and price of this model.

On the sides of the bucket are skiing, snow tools that guide.Adjusting the height to which they are raised, it is possible to achieve the required distance from the surface of the remoteness of the bucket cover.Also at its edge set scoring knives that simplify cleaning caked layers.
