PROBLEM TO BE SOLVED: To provide a water-weed recovery device capable of carrying out both of the reaping of the water weed and the transportation of the reaped water weed by one device. SOLUTION: The water-weed recovery device is constituted as follows. A main shaft 12 of a pump part 10 for transporting the water weed is extended from a sucking opening 18 of a casing 16 for housing an impeller 15 attached to the circumference of the main shaft 12 so as to be protruded, and the main shaft-extended part 20 is fixed to the lower end part of the main shaft 12 coaxially with the main shaft 12. A plurality of water plant cutters 24 and 25 is radially fixed to each of two positions in the shaft direction of the main shaft-extended part 20. When the main shaft 12 of the pump part 10 is rotated, the water weed is reaped by the rotation of the water weed cutter 24 and 25, and a sucking force is caused by the rotation of the impeller 15. The reaped water plant is directly sucked by the pump part 10 with the water by the sucking force to enable the reaping of the water weed and the transportation of the reaped water weed to be carried out by one device.
