<p>The material sieving device (3) comprises a vibrator unit (7) coupled to a vibratable sieving grid (8), adjacent to which is a compartment (9) for unsieved material. A hinge (10) is available between the grid and the scoop (2) of the work machine, and means (11) are provided for rotating a part (3a) of the sieving device (3) between positions facing the scoop and turned away from it. Two sieving grids (8, 15) can be envisaged, one fixed and the other rotatable (15) to vary the size of the granules of the material (5') passing through them.</p> |
