Feeding hopper with cutter suction boat

The invention provides a feeding hopper with a cutter suction boat. The feeding hopper comprises a hopper body, a mud door, an opening and closing system, a water feeding system, a discharge pipelineand a hoisting portion, wherein the hopper body has a hollow structure, and is connected with the discharge pipeline; the opening and closing system is used for controlling a communication state between the hopper body and the discharging pipeline; the water feeding system is separately connected with the hopper body and the discharging pipeline; the discharging pipeline is connected with a mud tube of the cutter suction boat; and the hoisting portion is movably connected with the feeding hopper and the cutter suction boat. By the feeding hopper, sand and impurities carried with the sand are prevented from being scattered in a construction process, water pollution is avoided, when not in construction, the feeding hopper can be lifted to a position above a water surface, and ship navigationsafety is not affected. 本
