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.

Abstract

The invention relates to a scraper system for a conveyor system (10) having a conveyor belt (12) and to a method for attaching a scraper module (24) to a scraper system (20). The scraper system (20) comprises a system carrier (22) and a plurality of scraper modules (24) for contacting the conveyor belt (12). The scraper modules (24) are attached to a module carrier (30), which extends on the system carrier (22) parallel to the system carrier. The module carrier (30) is releasably attached to the system carrier (22) by means of a clamping assembly for applying a clamping force in a direction perpendicular to the system carrier (22). The clamping assembly has a clamping rod (50), which runs parallel to the system carrier and applies the clamping force by means of a wedge action.

Abstract

The invention relates to a stripper system for belt conveyors, comprising at least one adjustable, spring-mounted system support running transversely to the direction of travel of the belt conveyor, on which one or more stripper blocks (2) made from an elastomer are interchangeably secured next to one another. The system support (3) is suspended on both sides of a tripper pulley (1) by means of a support mounting so that said support system can rotate about a support axis of rotation (5), and the support axis of rotation (5) impresses, by means of a spring device, a predefinable torque which is directed counter to the rotational direction of the tripper pulley (1) and the support axis of rotation (5) allows the system support to rotate about an angle of rotation such that the system support together with its stripper blocks (2) can swing away. The spring device comprises an adjusting spring (26), a damper spring (27) which is coupled thereto, and a spring bolt (33) designed as a pull rod. Both springs (26,27) are connected to the support mounting, and the spring bolt (33) comprises a section which initially actuates the damper spring (27) when it is determined that the adjusting spring (26) has travelled a prescribed distance.

Abstract

A belt-stripper module for a conveyor belt includes a stripping body. The stripping body includes a cutter carrier, a stripping blade attached thereto and a stripping edge unit attached to the stripping blade. The cutter carrier is rotatable about a stripping-body axis of rotation. The stripping edge unit is positionable so as to form an obtuse angle β relative to the conveyor belt in a running direction of the conveyor belt and to rest against the conveyor belt at an acute angle α, as measured at a right angle to the running direction and as seen in direction of the belt surface. The stripping-body axis of rotation intersects the stripping edge unit of the stripping blade at a point of intersection. A stripping-body pivot axis connecting the base and stripping body, as seen in the running direction, is located in front of the point of intersection.
