Description
Technical field
The utility model belongs to dredging plant technical field more particularly to a kind of dredging strand for being easy to remove blocking sundries
Knife.
Background technique
The reamer of existing cutter suction dredger generally comprises cutter hub, a plurality of spiral tool arm is equipped on cutter hub, each
Multiple tool aprons are equipped with along the trend of tool arm on tool arm, discrete cutter tooth is installed on each tool apron.When reamer operates, cutter tooth pair
Mining position carries out continuing scraping, when reamer abrasion, can carry out dismounting and change to the reamer of abrasion.
The reamer of above structure has the following problems in real-world operation: under certain water area conditions, such as containing a large amount of wood
Head or the like, coastal aquaculture region etc., the cutter tooth of reamer are easy to prick into wood or by ribbons such as fishing net, kelps
It rolls, the gap eventually led between the adjacent tool arm of reamer is blocked, and causes reamer to fail, can not carry out continuing to excavate.
At the same time, existing reamer is when excavating sandy gravel, rubble matter great soil group, due to containing large-size rock fragment in the soil body,
Such block stone, which enters inside dredge pump, easily breaks pump gallbladder, increases abrasion, reduces pump efficiency；Part stone, which is stuck in inside impeller, can also make
Machine run disequilibrium damages drive bearing support fixed screw, causes engine-damaged accident.The maintenance of the vessel time is caused to increase,
It reduces ship time availability and productivity of dredging, makes to dredge the poly- increasing of cost.
To sum up, need to optimize the structure of reamer, promoted applicability of the reamer under specific condition, promoted it is anti-
The ability of stifled pump.In order to promote the ability of anti-stifled pump, it is a relatively reasonable processing that grid, which is arranged, between the tool arm of reamer
Mode, however found in operation after installing grid additional, it is some wooden with the approximate sundries of grate opening pore size such as cobble, bulk
It is first-class or be easy to be stuck in grate opening and be difficult to dismantle these sundries after card resistance, manpower or machinery can only be passed through
Brute-force above-mentioned sundries is beaten into extrusion.On the other hand, it for sundries flexible for fishing net etc., is wound twisting to inhale in work progress
It is more difficult situation on reamer cutter hub, since flexible sundries can be embedded in the sky of reamer under the action of huge twisting resistance
It gap and is tensioned, thus it is very complicated laborious in cleaning, delay engineering progress.
