Description of the Related Art Conventionally, when crushing seabeds and lake bottoms, particularly rocks and the like, and dredging the rocks, a crushing tool is hung from the hoisting machine on the hull to the water bottom to crush the rocks and dredge the crushed rocks. I was working. In the conventional weight-type crusher used as such an underwater rock crushing device, the rock is crushed solely by its own weight of the crushed rock bar only by the drop impact force, so the crushing force is weak, especially when the depth of the water bottom becomes deeper. The crushing energy is reduced due to the resistance of the water, and when the crusher is dropped from a high position in the air, noise is generated when the crusher is dropped on the water surface.
