Description
Technical field
The invention belongs to field of mechanical technique, is related to a kind of structure improved cutter suction dredger.
Background technology
The task of dredger is to carry out the construction of the underwater cubic metre of earth and stone, is exactly specifically：Digging is deep, widens and clears up existing boat
Road and harbour；Excavate new navigation channel, harbour and canal；Dredge harbour, dock, ship lock and other hydraulic structures foundation trench and
The silt dug out is thrown into deep-sea or hydraulic reclamation to build up fields in land depression, is the sharp weapon blown sand and fill out sea.
Dredging tube is reached underwater mud layer surface by cutter suction dredger from ship side or ship stern, and the dredge pump started in cabin will
River sediment is aspirated, conveyed, being loaded and unloaded into ships that transport or direct CIF landed.
Due to bed mud sand bed deposition, it is hardened, be not easy to directly aspirate, the strand that rotation is often installed near suction pipe mouth is cut
River sediment is cut and stirred to reach by device is easy to the purpose that suction improves work efficiency.
Existing cutter suction dredger is provided with reamer using deep to water-bed twisting sucker head, twisting sucker head front end, and reamer rear portion is set
The mud suction mouth of connection dredging tube is equipped with, the water-bed silt of reamer twist passes it to dredging tube, realizes the collection to silt, but
The twisting sucker head suction mud efficiency of only reamer is low at present, and suction mud scope is small, and the water high concentration of sediment of suction is few.
The content of the invention
The purpose of the present invention is above mentioned problem be present for existing technology, it is proposed that a kind of structure improved strand suction is dredged
Ship, the technical problems to be solved by the invention are：How the efficiency of the work of dredger is improved.
The purpose of the present invention can be realized by following technical proposal：A kind of structure improved cutter suction dredger, including ship
Body, the inside of the hull have spoil hopper, and the bow of the hull is hinged with fixed mount, suction mud is provided with the fixed mount
