ABSTRACT:
The invention relates to a bucket crusher to be mounted in place of the bucket of an excavator or a bucket loader. Horizontal crushing shafts (12) provided with crushing tools are superimposed at a small distance from each other and adapted to be rotated in the same rotating direction. A pivoting axle (4) for a pivotably journalled compression and feeding plate (1) is located in the top section of the bucket. The plate (1) can be turned for pressing the material to be crushed against the crushing shafts, whose rotating direction is selected in such a manner that the crushing tools within said bucket travel towards said pivoting axle (4).
