1. A scraper for a conveyor belt, having
a system carrier with at least one scraper module,
wherein the scraper module has a base element arranged on the system carrier and a scraper element for abutting against the conveyor belt,
wherein the scraper element is rotatably attached with a rotational coupling about a rotational axis with respect to the base element, wherein the rotational coupling is configured such that,
in a rotational position of the scraper element within a fixed angular range, the scraper element is firmly coupled to the base element in the direction of the rotational axis to allow free bidirectional rotation of the scraper element within the fixed angular range while following a contour of the conveyor belt and maintaining alignment relative to the base element without, during said free bidirectional rotation, separating the scraper element from the base element even as external forces act upon the scraper element,
and in a rotational position of the scraper element within a release angular range, the scraper element can be detached from the base element in the direction of the rotational axis.
