When the conveyor 2 is rotated about the horizontal axis 5 by the driving ropes 24 to be in the upper inclined posture C or the lower inclined posture D, and when the conveyor 2 is in the upper inclined posture C, the floating objects 6 are moved. When the conveyor 2 is lifted to the stern side by the movement of the conveyor surface and dropped into the container 18 and collected, and the conveyor 2 is in the downward inclined posture D, the floating material 6 is moved underwater by the movement of the conveyor surface of the conveyor 2. To be lifted in the concave portion 19 and collected by driving the collection pump P.
Since the method of recovering the floating material 6 is selected, if the floating material 6 is particularly oil, it is possible to recover the floating material 6 according to its viscosity, and therefore, it is possible to improve the recovery efficiency of the floating material 6.
