Ground crushing and screening device for a bucket (12), of a fixed screen or other, comprising a blade (10) having first constraint end (42) to be keyed to a rotating roller (28), a second end (44) opposite the first end (42), and an intermediate connection body (46) between the first end (42) and the second end (44), which has a development in a substantially linear direction (L), in use directed radially with respect to the roller (28) on which the blade is keyed. The second end (44) of the blade has a fragmentation profile inclined backward with respect to a direction of rotation (F) of the roller (28) having at least a segment (48) inclined by a desired first acute angle (±1) with respect to the direction (L) of development of the intermediate body (46).
