Abstract: A bucket for crushing and screening stone and similar materials. The bucket has a scoop-shaped body defining an inlet opening for the stone to be crushed and an outlet opening for the crushed stone, between which a direction of flow of the stone is defined. The bucket further has a stone-crushing mechanism including a first jaw and a second jaw housed in the scoop-shaped body and movable relative to one another. The bucket still further has an element for moving the first jaw relative to the second jaw. The element imparts to the first jaw a combined rotational and translational movement relative to the second jaw in which a first component of the movement is away from and towards the second jaw and a second component of the movement is substantially parallel to the direction of flow.
