The mode described in the utility model that is fixedly connected can be replaced with the conventional technical means such as welding, being bolted.

The drag head that mud is inhaled for seabed dredging described in the utility model embodiment, including the rubbish isolated column 5 of front end, the One soil crushes plough, the second soil crushes plough, harrows chamber 1 and great Shi isolated columns 6.Rubbish isolated column 5 is located at drag head forward edge, by A piece filled circles bar construction serves and limits seabed depth and obstruction seabed rubbish；It includes first rotating shaft 4 that first soil, which crushes plough, Shovel 8 is crushed with two, each shovel 8 that crushes includes four the first fan-shaped shovel pieces, and the first soil crushes plough and is located at rubbish isolated column 5 In the middle part of rear side, drag head, it includes the second shaft 9 and eight group of second shovel piece 10 that the second soil, which crushes plough, and every group of second shovel piece 10 is by four The second shovel piece of piece 10 is constituted, and the second soil crushes plough in the middle part of the first soil crushing plough rear side, drag head, and the crushing of the first soil is ploughed Plough is crushed with the second soil and stretches into seabed below ground, and the first soil crushes main rise of plough and destroys digging action, the second soil It crushes plough and mainly plays crushing, stirring.And the first soil crushes plough and the second soil crushes the depth that plough stretches into seabed ground It is all higher than the depth that rubbish isolated column 5 stretches into seabed ground, the first soil crushes plough and is connected to rake by first rotating shaft 4 and bearing On head, with 20 ° of angle between the axial direction and drag head direction of travel of first rotating shaft 4, before drag head is dragged with dredger When row, the first soil crushes plough rotation to play destruction digging action；Second soil crushes plough and passes through the second shaft 9 and bearing It is connected on drag head, the second shaft 9 is connected with driving device, and driving device can be that hydraulic motor may be waterproof machine The second soil is enabled to crush plough rotation Deng, the exportable power of hydraulic motor.Hydraulic motor connects the oil on the hull of sea by oil pipe Hydraulic pump is arranged on oil pipe in case, controls the rotating speed of hydraulic motor by controlling the pressure of hydraulic oil, is dragged with dredger in drag head When dynamic forward, the second soil crushes plough rotation to play the role of crushing, stirring；Rake chamber 1 is located at drag head rear portion, is converged in loudspeaker Formula；The most narrow place of dredging tube connection rake chamber 1（Harrow the end of chamber 1）, dredger is connect on dredging tube, and dredging tube passes through on dredger Centrifugal pump generate pull of vacuum, the soil after crushing is drawn on dredger；Great Shi isolated columns 6 are located at the head end of rake chamber 1, greatly Stone isolated column 6 is that the iron of more laid out in parallel is constituted, and the rear side of body structure 3 is arranged rake teeth 7, rake teeth 7 by 5cm thickness iron plate It constitutes, the quantity of rake teeth 7 is 8-10, and rake teeth 7 is located at the rear side of great Shi isolated columns 6, the bulk sea obstructed by great Shi isolated columns 6 Stone can go out from the gap between two neighboring rake teeth 7.

Body structure 3 is made of one piece of top plate, two blocks of side plates, one piece of back plate and one piece of intermediate plate.Intermediate plate is for installing The first soil at left and right sides of it crushes plough.

Drag head and component materials are steel, wherein it is high-precision special-purpose steel to crush shovel 8 and the second shovel piece 10.

Dredging tube is tubulose steel, extends upwardly to dredger.

When specifically used, dredger is navigated by water to operation marine site, drag head is slowly put to seabed, dredger is started, is limited Speed, dragging drag head Forward, when drag head moves forward, rubbish isolated column 5 is automatically by seabed garbage blocking outside drag head, the first soil powder Broken plough, which destroys soil, to be excavated, and under the driving of hydraulic motor, the second soil crushes plough rotation and by soil crushing, stirring, drag head During Forward, soil is converged at automatically at rake 1 head end of chamber, and dredger centrifugal pump generates powerful suction, by soil by inhaling mud Pipe is passed up to dredger, when bulk sea stone is unable to inspiration rake chamber 1, is still stranded in rake 1 head end of chamber, when drag head moves ahead, greatly Block Hai Shi goes out from the gap between two neighboring rake teeth 7.

To sum up, by means of the above-mentioned technical proposal of the utility model, seabed rubbish, the first soil can be isolated when in use It crushing and ploughs inclined angle and break ground excavations, the second soil crushes plough and soil is rotated and crushed under the drive of hydraulic motor, thus Seabed soil can be fully crushed, and is quickly delivered to dredger cabin, avoids the occurrence of sucking seabed rubbish, ensures to inhale shale amount, Seabed is greatly promoted simultaneously and inhales mud efficiency, is used manpower and material resources sparingly.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
