Both side plates 3 and the bucket base plate 2 are configured to be attachable and detachable to and from each other. When excavating and transporting sediment M, both of the side plates 3 are attached to the bucket base plate 2 and become swingable together with the bucket base plate 2. When discharging the sediment M, the bucket body 1 turns under its own weight and the side plates 3 are separated from the bucket base plate 2. |
