ABSTRACT:
A rotary grid-structure bucket for separating fine and coarse constituents of sizable materials or products, has a bucket (3) with a separating part (9) located between its back (7) and its front (8) and sides provided with apertures to allow fine constituents (4) of the sizable materials or products (6) to pass therethrough. To make it possible for the separating part (9) to be exploited in its entire length the sides of the separating part diverge symmetrically with respect to the axis of rotation (R) in a forward direction. Ahead of the separating part (9) the bucket has a front part (25) whose sides diverge around the axis of rotation (R) in a forward direction in a lesser degree in relation to the axis of rotation (R) than the sides of the separating part (9) or extend in parallel with the axis of rotation (R) or converge in relation to the axis of rotation (R). The implement carrier (1, 2) is adapted to maintain the bucket (3) during rotation such that the momentarily lowermost portion (9a) of the sides of the separating part (9) as seen from the side extend horizontally (H) while the portion (25a) of the sides of the front part (25), which is momentarily lowermost during rotation as seen from the side, extend in an upward direction (U), resulting in distribution of the sizable materials or products (6) during rotation of the bucket (3) along the separating part (9), while the sizable materials or products (6) are prevented from falling out through the front (8) of the bucket (3) in that the momentarily lowermost portion (25a) of the sides of the front part (25) forms a threshold ahead of the separating part (9).
