Abstract

The invention relates to a beating arrangement for a rotary shredder, comprising abase body (12) which is rotationally arranged around an axis (20) and a cutting body (16) which is detachably fixed onto a protruding part (22) of the base body. A protruding profile (50) is formed on the front surfacethereof in the direction of rotation whereon the cutting body (16) forms a positive fit. The profile (50) can be embodied in the form of a protruding truncated pyramid, whose base surface lies on the plane of the front surface (24) of the protruding parts. The cutting body (16) can comprise two cutting edges (30, 32) which are bilaterally symmetrical in relation to a surface which extends tangentially in relation to a circumference of rotation. The cutting body can be fixed by means of a screw (14), which extends through the centre of the cutting body and the profile.

Description

technical field

[0001] The present invention relates to a hammer assembly for a hammer mill having a body rotatably mounted about an axis and a cutter body releasably secured to a protrusion of the body. Such hammer blades are used as striking tools for hammer mills that crush plastics, wood, and the like. Background technique

[0002] German patent DE 3545708C2 discloses a rotary hammer assembly in which the toothed cutter body is releasably fixed with its shaft in a groove. This fastening is achieved by means of a screw which passes through a bore in the main body and the shaft of the cutter body. The shaft is equipped with a flange on its end around a protrusion in the groove. Furthermore, the shaft has a formation protruding into a complementary shaped formation within the groove. In this way, the teeth remain in their position even when strong forces are present. Typically, the hammer head is worn to form an edge in the direction of rotation of the hammer. Due to t...
