Spreader for ice prevention materials in liquid and granulated form, for winter road maintenance

摘要

The spreader has a spinning ejection disc (1), which rotates about a vertical axis (9), and has at least two ejection vanes (3',3") running in directions which have radial components with respect to the axis. Granulated material is distributed to one vane (3'), and liquid material is distributed to the other (3"). The vanes are aligned over the disc, such that the liquid and granulated material streams cross before they reach the ground or road surface, in order for the granulated material to be soaked or moistened as required. The spreader may also be equipped with groups of vanes, and the stream directions may be set at a small angle to each other, especially at an angle of less than 5 degrees.
