Patent ID: 7243803

Claim:
A recovery apparatus comprising: a reserve tank which stores liquid containing a floating matter; an endless running member which runs between a first position where the member is immersed in the liquid stored in the reserve tank and a second position where the member projects upwards from a surface level of the liquid; and a bucket which is rotatably couped to the endless running member by a pivot pin, the bucket including an opening for allowing the liquid containing the flowing matter to flow in the bucket, the bucket being held, with the opening facing upward, and scooping the liquid containing the floating matter through the opening, while the bucket is being moved from the first position to the second position of the running member, and the bucket being rotated to make the opening face sideward, and exhaust the floating matter contained in the scooped liquid from the bucket through the opening, when the bucket is located at the second position; wherein the bucket comprises: a bucket body which includes the opening and discharge ports which communicate with an inside of the bucket at a position lower than that of a rim of the opening to cause the liquid in the bucket body to be exhausted therefrom, while the bucket is being moved from the first position to the second position, the bucket body having a corner of an acute angle at an end that faces the opening, and the bucket body being held, with the opening facing sideward with respect to the surface level of the liquid, and the corner located to extend downward, while being moved from the second position to the first position; partition plates which extend from the rim of the opening toward the inside of the bucket body to face each other, the partition plates being located between the discharge ports and the opening, and also blocking flowing of the floating matter from the opening to make the floating matter stay between the partition plates, when the bucket is being moved from the first position to the second position.
