A rolling bearing is respectively adorned at the two ends of two helical conveyors, and bearing support is installed in respectively in the bearing of operating mechanism's housing.Two helical conveyor rotation directions are opposite, stud with antifriction alloy along the helix periphery and beat the snow piece, and two helical conveyors are used interchangeably.

The utility model can reach following good effect:

(1) snow removing machine adopts hydraulic drive obviously to be better than machine driving, and the easier layout of hydraulic drive, makes complete machine structure elegant in appearance.

(2) adopt double helical conveyor, make the helical conveyor tactical diameter big, the snow removing width is also big, and the snow removing maximum ga(u)ge can reach 1.3 meters when keeping off with creeping.

(3) when removing the bigger snow deposit of thickness, but layering is carried out; When accumulated snow thickness surpasses operating mechanism, cut off top snow deposit with the last cutting of housing side.

(4) because two helical conveyor rotation directions are opposite, its helix common vertex staggers 180 °, the imbalance when having overcome two helical conveyor duties.
