Description
Technical field
The present invention relates to Dredging Technology field, more particularly to a kind of digging cohesive soil reamer.
Background technology
At present, reamer head used in China's cutter suction dredger is largely in addition to six arms dig the special reamer head of rock
The universal reamer head of six arms.Dredging for cohesive soil, frequently with the universal reamer head of six arms, since cohesive soil is with stronger
Adhesiveness, can be frequently encountered during dredging cohesive soil reamer head it is attached by cohesive soil bag so that block reamer between gap most
The phenomenon of stifled knife eventually, after stifled knife phenomenon occurs, can only suspension of works, by manually shoveled with engineer remove bag be attached to it is viscous on reamer
It could continue to construct after property soil, seriously affect construction efficiency.
Traditional universal reamer of six arms is six arm reamers, and wheel hub section is smaller by spacing, is found by construction site, is glued
Property attachment of the soil on reamer head be to assemble since hub end, keep together and gradually spread to great circle end, finally block
Whole reamer head.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of digging cohesive soil reamer, existing in the prior art to overcome
Drawbacks described above.
In order to solve the above technical problems, the technical scheme is that：
One kind digs cohesive soil reamer, including reamer foundation ring, reamer wheel hub, reamer arm and reamer tooth, on the reamer wheel hub
Portion is evenly distributed with five blocks of wing plates, between the axis angle of the wing plate and the reamer wheel hub is 40 °~50 °, the reamer
One end of arm is welded and fixed with the wing plate, and the other end is welded and fixed and is evenly distributed on the upper surface of the reamer foundation ring, institute
State and some reamer tooths are installed on the outer edge of reamer arm.
As preferable technical solution, the reamer tooth and the angle of reamer foundation ring tangential direction are 40 °~50 °.It is best
It is 43 °.
As preferable technical solution, five pieces of reamer toothholders, the reamer tooth installation are evenly equipped with the reamer foundation ring
On the reamer toothholder, each piece of reamer toothholder is corresponding with the position that the reamer arm is installed, the end of every piece of reamer toothholder
Tangential direction of the face perpendicular to the reamer foundation ring.
As preferable technical solution, the axis angle of the wing plate and the reamer wheel hub is 43 °.
As preferable technical solution, the contour line of the reamer arm is gaily decorated basket type space curve structure.
As preferable technical solution, the cylinder bottom of the reamer wheel hub opens up endoporus, and thread groove is furnished with hole, leads to
Cross and mangler shaft thread connection.The thread groove is preferably trapezoidal.
As preferable technical solution, some reamer toothholders, the reamer tooth are installed on the outer edge of the reamer arm
On the reamer toothholder.
As further preferred technical solution, 7-10 reamer toothholder is respectively welded on each reamer arm, preferably 8
Reamer toothholder.
It is of the invention compared with traditional universal reamer of six arms, have the advantages that：
1), reduce tool arm quantity, add the spacing between tool arm；
2) the tool arm curve at wheel hub section, is changed so that tool arm contour line is changed to by universal partially tapered of six arms
Inclined gaily decorated basket type, i.e., expand outwardly, the minimum for adding reamer arm wheel hub section passes through spacing in wheel hub.
3), by reducing the cutting angle of reamer tooth, reamer single thickness of cutting is reduced, is twisted so as to reduce single and enter
The sticky earth volume of knife.
4), by entering the method for earth volume between increasing the space between wheel hub section tool arm, reducing tool arm, strand is reduced
The cohesive soil concentration of knife wheel hub, avoids the cohesive soil unity phenomenon between reamer tooth, so that effectively evading reamer head blocks up knife
The generation of phenomenon, ensure that the construction efficiency of cutter suction dredger.

Embodiment
As shown in Figure 1 and Figure 4, it is a kind of to dig cohesive soil reamer, including reamer foundation ring 1, reamer wheel hub 2, reamer arm 3 and reamer
Tooth 5,2 top of reamer wheel hub are evenly distributed with five blocks of wing plates 201, and the axis of the wing plate 201 and the reamer wheel hub 2 presss from both sides
Angle is 43 °, and wing plate 201 and the cylinder wheel of reamer wheel hub 2 are integrally cast as one, is provided firmly for reamer arm 3
Basis and the plane easy to welding.One end of the reamer arm 3 is welded and fixed with the wing plate 201, and the other end is welded and fixed simultaneously
The upper surface of the reamer foundation ring 1 is evenly distributed on, some reamer tooths 5 are installed on the outer edge of the reamer arm 3.The strand
The cylinder bottom of break bar hub 2 opens up endoporus, and thread groove is furnished with hole, by with mangler shaft thread connection.The work of the present invention
Principle is：The torque of mangler shaft is transmitted by reamer wheel hub 2, so as to drive reamer to rotate cutting soil.
As a preferred embodiment, the reamer tooth 5 and the angle of 1 tangential direction of reamer foundation ring are 40 ° -50 °.It is best

Secondary thickness of cutting, under equal conditions, thickness of cutting reduce 5-8mm.
As shown in figure 3, as a preferred embodiment, five pieces of reamer toothholders 4, institute are evenly equipped with the reamer foundation ring 1
Reamer tooth 5 is stated on the reamer toothholder 4, each piece of reamer toothholder 4 is corresponding with the position that the reamer arm 3 is installed,
Tangential direction of the end face of every piece of reamer toothholder 4 perpendicular to the reamer foundation ring 1.So that reamer tooth cutting direction is with twisting during rotation
Knife foundation ring tangential direction is identical.
As shown in figure 5, as a preferred embodiment, the contour line of the reamer arm 3 is gaily decorated basket type space curve structure,
Totally five pieces, it is fixed by welding between reamer wheel hub 2 and reamer foundation ring 1.As shown in Fig. 2, its contour line 7 is more general than with six arms
Reamer contour line 6 is compared, and the curve of wheel hub is expanded outwardly so that tool arm contour line is by the universal partially tapered change of six arms
For inclined gaily decorated basket type, the minimum by spacing of reamer arm wheel hub section is added with this, under the same terms, wheel hub section minimum passes through spacing
Increase 20mm, tool arm ensemble average spacing increase 150mm.
As shown in fig. 6, as a preferred embodiment, some reamer toothholders are installed on the outer edge of the reamer arm 3
4, the reamer tooth 5 is installed on the reamer toothholder 4, and the reamer toothholder 4 and reamer tooth 5 are used cooperatively, each reamer
7-10 reamer toothholder 4 is respectively welded on arm 3, preferably 8 reamer toothholders 4.
