Abstract
The utility model relates to a work piece for a trailing suction hopper dredge, comprising a suction pipe (1), a cover (2) and a rabble blade base (4), which could be used for the river, lake and sea dredging and the channel dredging. The utility model compared to the prior technology could dredge in the hard soil and is fit for a plurality of soil conditions, which has the advantages of less drag resistance and good loosen effect and could greatly improve the mud suction concentration of a pump and the efficiency of the dredge. The utility model could be widely applied with trailing suction hopper dredge.
Description
The utility model is a kind of workpiece of drag suction dredger, is used for river, river, lake, dredge in the sea and the waterway dredging operation.
Drag suction dredger is widely used in the desilting and the waterway dredging in river, river, lake, sea, its rake teeth form mainly contains straight-tooth and colter formula, effect still can under soft soil condition, but under pan soil matter condition, loose ability to soil is relatively poor, make pump inhale concentration of hydraulic mixture and descend greatly, had a strong impact on the operating efficiency of drag suction dredger, operating cost obviously improves.
At the problem that above-mentioned prior art exists, the purpose of this utility model is the novel rake teeth of a kind of drag suction dredger of design, improves the ability of loosening the soil of rake teeth, improves the operating efficiency that pump is inhaled concentration of hydraulic mixture and drag suction dredger.
The utility model is to be made of dredging tube (1), case (2), rake teeth seat (3), rake teeth (4).(20 link together dredging tube (1) with case, rake teeth seat (3) is hinged on dredging tube (1) and the case (2), in the below of rake teeth seat (3) 2-8 rake teeth (4) is installed, rake teeth (4) is made up of side cutting knife (6) and bed plate (7), side cutting knife (6) symmetry is installed in the top of bed plate (7) both sides, bed plate (7) and horizontal plane make progress into 0～60 angle, side cutting knife (6) becomes 0～90 angle with horizontal plane on the elevation direction, on side view orientation,, have cutting edge in the front of side cutting knife (6) and bed plate (7) with tilt 0～90 angle of plumb line.
Described embodiment is further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is the lateral view of structure diagram of the present utility model.
Accompanying drawing 2 is the front elevation drawing of structure diagram of the present utility model.
Accompanying drawing 3 is the lateral view of rake teeth structure of the present utility model.
Accompanying drawing 4 is the front elevation drawing of rake teeth structure of the present utility model.
The related novel rake teeth of drag suction dredger of the utility model is by being made of dredging tube (1), case (2), rake teeth seat (3), rake teeth (4).Rake teeth seat (3) is hinged on dredging tube (1) and the case (2), in the below of rake teeth seat (3) 3 rake teeths (4) are installed, rake teeth (4) is made up of side cutting knife (6) and bed plate (7), side cutting knife (6) symmetry is installed in the top of bed plate (7) both sides, and bed plate (7) and horizontal plane make progress into 30 angle, and side cutting knife (6) becomes 60 angle with horizontal plane on the elevation direction, on side view orientation, recede 30, have sharpening mouth down in the front of side cutting knife (6) and bed plate (7) with plumb line.Rake teeth group and dredging tube link together during work, draw by dredge boat, rake teeth with dredge boat in the river, the bottom motion in river, lake, sea, simultaneously with the loosing soil of bottom, under the suction of slush pump, will be inhaled and deliver on the dredge boat, finish the desilting and the waterway dredging operation in river, river, lake, sea by the soil that rake teeth loosens.
The utility model compared with prior art can operation under harder soil condition, adapts to The soil property condition extensive,, have the traction resistance little, loosing soil is effective, can significantly improve Pump is inhaled the operation efficient of mud concentration and drag suction dredger. The utility model can dig in the rake suction Mud ship wide popularization and application.
Claims (1)
- The utility model is by dredging tube (1), case (2), rake teeth seat (3), rake teeth (4) constitutes, it is characterized in that rake teeth seat (3) is hinged on dredging tube (1) and the case (2), in the below of rake teeth seat (3) 2-8 rake teeth (4) is installed, rake teeth (4) is made up of side cutting knife (6) and bed plate (7), side cutting knife (6) symmetry is installed in the top of bed plate (7) both sides, bed plate (7) and horizontal plane make progress into 0～60 ° angle, side cutting knife (6) becomes 0～90 ° angle with horizontal plane on the elevation direction, on side view orientation,, have cutting edge in the front of side cutting knife (6) and bed plate (7) with tilt 0～0 ° angle of plumb line.
