An excavator bucket which is intended to be coupled to a machine 1 and is used to grade masses with different particle sizes. The bucket comprises, on the one hand, two screens 13, 15 arranged in the lower part of the bucket 2 at a distance from each other and essentially parallel to each other, of which the upper screen has a greater mesh width than the bottom screen, and, on the other hand, a drive arrangement 8 - 10 which is coupled to at least one screen in order to give it a shaking movement. <IMAGE> |
