Abstract
A belt scraper having a scraper element to be brought into abutment with a belt. The scraper element is pivotably arranged with reference to a pivoting axis. A spring element generates a torque acting on the scraper element. A sensor for determining a pivoting angle of the scraper element is a contactless sensor with an index part and a detecting part for detecting the position of the index part. The index part is arranged, at a distance from the pivoting axis, on a movable element that is coupled to the scraper element.
Claims14
A belt scraper with
- a scraper element to be brought into abutment with a belt,
- wherein the scraper element is pivotably arranged with reference to a pivoting axis, wherein a spring element generates a torque acting on the scraper element, wherein said spring element is a helical spring, a leaf spring, a torsion rod spring, a plate spring, or a block spring,
- and wherein a sensor is provided for determining a pivoting angle of the scraper element,
- wherein
- the sensor is a contactless sensor which has an index part and a detecting part for detecting the position of the index part relative to the detecting part,
- wherein the index part is arranged, at a distance from the pivoting axis, on a movable element that is coupled with the scraper element.
