Blower head

HB-S automotive high-performance snow blower

 

The blower head of the HB-S features 2 blower wheels with nominal diameters and depths that are designed for the required clearing capacity. The two blower wheels rotate in opposite directions. They are protected against damage by shear pins and are driven by the vehicle via cardan shafts. A pre-cutting device is flanged to each blower wheel via an extension shaft for the purpose of breaking up hard-packed snow. The hydraulically swivelling upper pre-cutting devices for removing high levels of snow are fitted above the blower wheels. Every precutting device is protected against breakage by shear pins.

 

The snow is transported to the blower wheels via a funnel-shaped component, the snow guiding device. The blower wheels are running in the so-called blower wheel housings. Each blower wheel housing is equipped with a tangential chute, through which the snow is ejected over a distance of up to 40 m. 

 

Hydraulically operated feed plates are fitted on the outsides of the snow guiding devices. By opening up these feed plates, the clearing width can be increased. In addition, the two blower head halves can be hydraulically extended. 

 

Two strong pivots (on the right and left) are welded into the vehicle`s support frame. The rocker is mounted on these pivots (similarly to the mounting of a bulldozer blade). The rocker is screwed onto the sliding frame. The entire blower head is thus hydraulically height-adjustable (clearing height) via the rocker. The desired clearing height above the top of the rail can be adjusted manually via a hand wheel on the rocker.

 

Snow deposits above the rocker (behind the blower head) can be removed hydraulically by means of ejection flaps.
