Bucket for loading and unloading

摘要

The bucket (100) has a front wall (110) and a rear wall (120) joined by a bottom wall (130). An endless screw (140) is longitudinally disposed against the bottom wall for unloading contents across flanks, where the flanks are free of a closing wall. An articulated arm (250) is moved between a flank closing position, in which the front wall and rear wall are joined, and a flank disengagement position.
