The invention provides a novel dredging device. The novel dredging device comprises a hull, a conveyor belt, a receiving hopper, a dredging mechanism and a lifting mechanism, the dredging mechanism comprises a support frame, mud poking blades, mud stirring shafts, moderatingelectric motors, a bevel gear I, a bevel gear II and an electric motor I, the support frame is welded to the lifting mechanism, the two ends of the mud poking blades are respectively mounted on the support frame throughbearings, the mud poking blades is connected with the electric motor I in a driving mode through the bevelgear I and the bevel gear II, the four mudstirring shafts are respectively mounted on the mud pokingbladesin an equal angle mode through the bearings, the four moderating electric motors are respectively fixedly mounted on the mud pokingblades, and the power output ends of the moderating electric motors are fixedly connected with the mudstirring shafts respectively.Silt is excavated throughthe mutuallyindependent rotating mud pokingblades and mudstirring shafts, so that the accumulated silt can be quickly cleaned and the cleaning effect is good, and the position of the dredging mechanism is changed through the lifting mechanism, so that the mud poking blades can fully excavate the slit, and the working radius is increased.
