<p>This invention shows how the effects of a bucket-mounted screening device in a loader/excavator can be made more efficient. The bucket, which is used for excavation, is equipped with a screen. In contrast to known techniques, by suspending the screen in the upper part of the bucket, a rocking motion can be imparted to the screen. The rocking movement, in contrast to a linear movement, results in the material on the screen being transported to the centre, which results in a faster through-flow of material.</p> |
