<p>A screen crusher for the bucket of an excavating machine or a bucket loader, the back wall of which, between the bottom plate (1a) and the pivoting joint (6) associated with the bucket boom, are formed into a crushing screen (2) which comprises crushing means (9) rotatable about a shaft (3), which means crush the material in the bucket as they rotate and at the same time deliver crushed material out of the bucket through the crushing screen (2). As seen in the direction of feed (F) of the crusher screen (2), there is a wearing plate (10) at the tail end of the crusher screen (2) which is positioned in such a way that a sharp-angled crusher jaw is formed between the wearing plate (10) and the said direction of feed (F). A plane which touches the circumferences of rotation (9') of the crushing means (9) on successive shafts (3) is above determined as the direction of feed (F).</p> |
