The radial scraper mechanism is for star-shaped or linear mineral stores. Above the ground a suspended beam (12) is located with a rope anchor (14). A scraping bucket (18) is provided and to it is fixed a digging rope (20) leading to a first winding drum (24). A lifting rope arrangement (22) leads from the scraping bucket over a head roller (28) provided on the beam point around a tension roller (28) to form a loop and to a second winding drum (26). The one winding drum winds up during at least a part movement of the scraping bucket, while the other unwinds. An adjustment device (50,52,54,56) moves the tension roller (50) to a linear guide (46,48) which is part of the rope anchor of the beam and pref. comprises at least two parallel rope strands. |
