The present invention relates to a snow-clearing device of the type which is adapted to be supported by a vehicle and which comprises a mould board (1) whose lower edge has at least one blade (11), which serves to abut, by a lower cutting edge, against the ground and to ensure a snow-cutting and snow-raising action and which is hingedly mounted in relation to the mould board and pivotable away against the action of a spring, thereby avoiding damage when running into an obstacle. The blade (11) is hingedly attached to a front end of at least one pivot member (9) which is directed forwards in relation to the mould board (1) and is pivotable downwards-backwards in relation to the pivot member from an upper stop position against the action of at least one first spring element (13), the pivot member being connected, in an area spaced from said front end, with a lower portion of the device and being pivotable upwards in relation thereto from a lower stop position against the action of at least one second spring element (14). |
