摘要

PROBLEM TO BE SOLVED: To provide a bucket for sludge dredge economically attainable by modifying merely the structure of a backhoe bucket and having good operability and high sludge sucking efficiency and a dredger using the bucket. SOLUTION: The approximately half of the area of the opening part of the backhoe bucket 1 on the side mounted on an arm is covered by a fixed cover 24. A movable cover 26 is so installed on the backhoe bucket 1 along the guide parts 35 formed at the left and right edges of the opening part as to be slid by a hydraulic cylinder 27. The movable cover 26 can cover an extra opening part 25 by moving from the state in which it covers the fixed cover 24 when the hydraulic cylinder 27 is extended. A water discharge window 41 for discharging water during the excavating is formed in the fixed cover 24. A small cover 43 opening outward is installed to close and open the water discharge window 41.
