Description
Technical field
The present invention relates to shield machine, more particularly to a kind of shield machine fish tail knife slip-casting mud mouth.
Background technology
Shield machine fish tail knife assembly generally includes center flange, the fish tail knife being fixedly mounted on center flange and peace
Loaded on the note mud nozzle on center flange, such as patent application of Publication No. CN105370292A, its note mud nozzle is in the form of a column,
Multiple spray orifices are offered on the side wall for noting mud nozzle, because emission direction and the mud of spray orifice are noting the flowing in mud nozzle
Direction is perpendicular, therefore certain flow velocity can be caused to be lost when mud sprays, it is impossible to thoroughly prevent from producing mud cake on fish tail knife,
And easily being internally formed the overstocked of mud in nozzle tip in turn results in blocking.
The content of the invention
The shield machine fish tail knife slip-casting mud of good and long service life it is an object of the invention to provide a kind of slip fluidity
Mouth.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of shield machine fish tail knife slip-casting mud mouth, it is wrapped
Installing pipe is included, the installation inside pipe wall has the erecting bed of annular, and the slip-casting mud mouth also includes being installed on the erecting bed
Note mud overhead gage, multiple note mud holes are offered on the note mud overhead gage, the note mud hole on the note mud overhead gage includes master
Hole and secondary orifices, the main aperture be divided into it is multigroup, centered on multigroup main aperture infall, the main aperture from note mud overhead gage center to
Surrounding is distributed in divergent shape, and the area of the main aperture is successively decreased laterally by center.
Optimization, the note mud mouth also includes that by bolt baffle plate pressing plate, the pressure that mud overhead gage is pressed on erecting bed will be noted
Note mud lower baffle plate and note mud packing ring between the note mud overhead gage and the erecting bed, the note mud lower baffle plate middle part opens up
Have note mud mouthful and its be located between the note mud overhead gage and note mud packing ring, the baffle plate pressing plate is pressed on the note mud overhead gage
Square and its middle part offers and notes mud through hole.
Optimization, the secondary orifices is uniformly distributed on the note mud overhead gage.
Optimization, the main aperture is divided into two groups, is arranged in decussation.
Further, the cross section of the main aperture is successively decreased laterally in isosceles trapezoid and area by center, on the note mud
The lower surface right-angled intersection connected in star of baffle plate, the center of groove is the center of main aperture infall, and recess width and depth are by center
Successively decrease to four ends, two waists of main aperture trapezoidal cross-section are located on the side of groove.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：Mud of the present invention is from note
Mud overhead gage sprays, and directly easily forming the overstocked position of the soil body to fish tail knife middle part notes mud, can thoroughly prevent the soil body from overstocking and be formed
Mud cake, and flow is consistent everywhere with installing pipe to note position of opening and size on mud overhead gage, does not result in flow velocity loss,
Also there will not be extra pressure to note mud overhead gage, greatly improve the service life of note mud overhead gage.

Specific embodiment
The invention will be further described for shown embodiment below in conjunction with the accompanying drawings.
Slip-casting mud mouth includes that inwall has the installing pipe 6 of the erecting bed of annular, is installed on the installation as shown in Figure 1, 2, 3
On platform and offer the note mud overhead gages 7 in multiple note mud holes, note mud overhead gage 7 is pressed on by baffle plate on erecting bed by bolt 14
Pressing plate 8, the note mud lower baffle plate 9 being pressed between the note mud overhead gage 7 and the erecting bed and note mud packing ring 10, under the note mud
The middle part of baffle plate 9 offers note mud mouthful and it is located between the note mud overhead gage 7 and note mud packing ring 10, and note mud packing ring 10 is without stone
Cotton pad piece, the baffle plate pressing plate 8 is pressed on the top of note mud overhead gage 7 and its middle part offers note mud through hole.As shown in figure 4,
Note mud hole on the note mud overhead gage 7 includes main aperture 11 and secondary orifices 12, and 11 points of the main aperture is two groups, is arranged in decussation
Cloth, the secondary orifices 12 is uniformly distributed on the note mud overhead gage 7.Centered on the infall of main aperture 11 described in two groups, the main aperture
11 cross section is successively decreased laterally in isosceles trapezoid and area by center, the lower surface cruciform shape of the note mud overhead gage 7
Groove, the center of groove is the center of the infall of main aperture 11, and recess width and depth are successively decreased from center to four ends, main aperture 11
Two waists of trapezoidal cross-section are located on the side of groove, and the design successively decreased from four circumferential centers by width and depth can be protected
The pressure of card slurry injection mud overhead gage 7 is uniform, because of long-term use note mud overhead gage 7 will not be caused to deform, and eliminates in the past
