The invention relates to a stripping element for placing on a system support or carrier of a stripping device for the discharge end of a conveyor belt, which has a stripping plate, which in the ready-to-operate position engages in stripping manner on the conveyor belt, a plate support, to whose upper end is fixed the stripping plate, a torsion spring joint on which the plate support is guided in pivotable and spring-loaded manner about a horizontal axis, a base on which is held the torsion spring joint and which is placed on the system carrier, a vertical adjustment device for the vertical adjustment of the stripping plate along a first axis, a pivot bearing for pivoting the stripping plate about a second axis for setting the parallelism of the stripping edge of the stripping plate with respect to the conveyor belt, the second axis forming an angle smaller than 90.degree. with the conveyor belt portion running onto the stripping plate.
European patent 254 977 discloses a stripping device for the return area of conveyor belts, which comprises an adjustable, fixed or resiliently mounted system carrier or support extending transversely to the conveyor belt running direction and a plurality of stripping elements in each case held on bases. The stripping elements are fixed in juxtaposed manner to the system carrier and in each case carry a stripping plate or disk set in stripping manner with respect to the conveyor belt movement direction. The stripping plates are mounted in pivoted manner by a torsion spring about an axis at right angles to the conveyor belt running direction and resiliently for an elastic deflection movement about said axis. A deflection movement is e.g. performed if obstacles adhering firmly to the conveyor belt strike the stripping plate. For the setting and engagement of the stripping plate on the associated belt area, each stripping element has a vertical adjustment device and for the preferably automatic setting of the parallelism of the stripping plate with respect to the conveyor belt has a pivot bearing for pivoting about an axis, which forms an angle smaller than 90.degree. with the conveyor belt portion running onto the stripping plate.
These known stripping elements have a high stripping capacity, because they also react rapidly to minor displacements of the conveyor belt underface or are easily adjustable and can automatically assume an optimum position for the stripping of impurities adhering to the conveyor belt.
