(54) A spreading device for a road-construction mass substance


(57) The invention relates to a spreading device (10) for a road-construction mass substance, which is intended to be used as an accessory to a work machine (14), and which includes
- a front frame (16) and a rear frame (18) connected to each other arranged to form a feed silo (20) for the road-construction mass to be spread,
- a throat opening (22) between the front frame (16) and the rear frame (18),
- a blade (24) fitted to the said rear frame (18),
- carrier wheels (28) articulated to the front frame (16), and
- a coupling (30) articulated to the rear frame (18),
- operating devices (38, 40) for adjusting the layer thickness of the road-construction mass to be spread.

The blade (24) is fitted to the said rear frame (18) vertically to its end next to the front frame (16), and in connection with the said blade (24) is a fine-adjustment operating device (40) for the fine adjustment of the height of the blade (24) during the spreading of the road-construction mass.
