River and lake desilting equipment

The utility model relates to the field of desilting equipment, in particular to river and lake desilting equipment, and aims to solve the problems that in the desilting process, a desilting pipe is prone to blockage when sucking objects such as stones, time and labor are wasted when blockages in the desilting pipe are manually taken out, secondary blockage is prone to occurring when the blockages are discharged into water, and therefore the desilting efficiency is affected. According to the scheme, the centrifugal pump is used for being placed on a ship to work along with the ship and is connected with the dredging end through the dredging pipe; the supporting plate is fixedly connected with the outer wall of the feeding end of the desilting pipe. A plurality of through holes are formed in the supporting plate, the outer edge of the supporting plate is connected with the outer edge of the cover-shaped flexible shell, the supporting plate is arranged behind the feeding end of the desilting pipe, the feeding en
