The invention relates to an inland barge unloading dredger. The inland barge unloading dredger is used for carrying out unloading dredging on the inland water area, and comprises a diesel generating set, a power distribution board, a frequency converter, a sludge pump motor, a flush water pump motor, a propelling motor, a sludge pump, a flush water pump, a sludge suction device, a flush water device, a propeller, a positioning pile and a ponton manoeuvring winch. The dredger can sail by itself without depending on a tug, use is flexible and convenient, full-power drive is adopted, a dredger power station composed of the diesel generating set and a power distribution unit provides for dredger propelling and all power equipment and devices, if a single electric generator fails, work of the dredger is not affected, the sludge pump and the flush water pump are driven through power, work stability and reliability are improved, a brand-new sludge blowing and flush water device is arranged, work is efficient and flexible, during sailing, the sludge suction device and the flush water device are taken back, the interior of a ship board is not affected by the inland waterway high limit, selfpositioning of the dredger and moving of a muck transport ship are finished through equipment arranged on the dredger, influences from the outside are avoided, the work range is wide, and the dredgeris compact and reasonable in arrangement, advanced in technology, safe, reliable, high in automation degree, good in economic benefit and good in market popularization prospects.
