[0002] The mud discharge pipe refers to the pipeline used by dredging machinery such as (cutter suction) dredging ships to transport mud. It is mostly made of plastic or steel pipes. Perforated mud discharge pipes are common. Cutter suction dredgers extend the mud suction pipe from the side or stern of the ship to the surface of the underwater mud layer, and start the mud suction pump in the cabin to suck, transport, and load and unload the riverbed mud to the transport ship or directly unload it to the shore. Due to the deposition and compaction of the riverbed mud layer, it is not easy to directly suck. A rotating cutting device is often installed near the suction pipe mouth to cut and stir the riverbed mud to make it easier to suck and improve work efficiency.

[0003] However, since a variable diameter pipe is often used at the end of the mud discharge pipe for mud spraying, although the energy consumption during mud discharge can be reduced, the inside of the variable diameter pipe is prone to accumulation of sludge, which dries up and affects the subsequent mud discharge effect.
