The present invention provides a device for recovering floating materials on the liquid surface which is capable of recovering reliably and efficiently even floating materials on the liquid surface such as scum and oil which are likely to flock and easily aggregate. A gate portion for recovering floating materials on the liquid surface is installed at a recovery portion in a state of following vertical movement of the liquid level and being able to move freely in the vertical direction, and the float is composed of a plurality of gate floats which are disposed around and in the vicinity of the gate portion and which float and retain the gate portion near the liquid level, and a plurality of main floats which are disposed further outside than the gate floats to float and support the recovery portion. The gate floats rotate around the gate portion, raking and gathering floating materials to the gate portion. The main floats are arranged in such a manner that at least a part installed with a blade-shaped projection is provided on the outer circumferential part and move rotationally or rotate along the liquid level, thereby crushing, separating and cleaving the floating materials on the liquid surface which flock. |
