That is, since the ejector-driven pump is disposed above the water surface, that part is not contaminated, and maintenance, inspection, and restoration of the device can be easily performed. The suction nozzle, the flexible tube around which the coil spring is wound, the suction pipe, the ejector, and the recovery case are successively connected to form the suction recovery device, and there are no parts that protrude from side to side. Furthermore, since the flexible tube directly above the suction nozzle is wrapped with a coiled spring and can be bent freely, the tip of the suction nozzle can be brought close to the corner of the bit. When the ejector-driven pump is driven, high-pressure water is sucked from the suction pipe and discharged from the ejector-driven pump via the flexible hose and supply pipe to the high-pressure water plenum chamber. From there, it is injected as a jet stream into the diffusion tube of the ejector, and then discharged into a collection case surrounded by a collection wire mesh (filter). On the other hand, the solids that have settled to the bottom are sucked together with water through the suction nozzle, flexible tube, and suction tube into the diffusion tube, where they merge with the high-pressure water and are collected in a collection case covered with a collection wire mesh (filter). released into the frame,
Solids are captured by a collection screen (filter). At that time, rotate the 2nd winder.
