Abstract

The invention discloses a kind of shield machine fish tail knife slip-casting mud mouths, it includes installing pipe, the installation inside pipe wall has the erecting bed of annular, the slip-casting mud mouth further includes the note mud overhead gage being installed on the erecting bed, multiple note mud holes are offered on the note mud overhead gage, note mud hole on the note mud overhead gage includes main aperture and secondary orifices, the main aperture is divided into multiple groups, centered on main aperture infall described in multiple groups, the main aperture is in divergent shape distribution by note mud overhead gage center around, and the area of the main aperture is successively decreased outward by center.Mud of the present invention is sprayed from note mud overhead gage, mud directly is infused to the easily overstocked position of the formation soil body in the middle part of fish tail knife, it can thoroughly prevent the soil body from overstocking and form mud cake, and infuse position of opening and size on mud overhead gage with flow is consistent everywhere in installing pipe, flow velocity loss is not will cause, there will not be extra pressure to note mud overhead gage, greatly improve the service life of note mud overhead gage.

Description

Shield machine fish tail knife slip-casting mud mouth
Technical field
The present invention relates to shield machine, in particular to a kind of shield machine fish tail knife slip-casting mud mouth.
Background technique
The fish tail knife and peace that shield machine generally includes center flange with fish tail knife assembly, is fixedly mounted on center flange It infuses mud nozzle such as the patent application of Publication No. CN105370292A loaded on the note mud nozzle on center flange and is in the form of a column, In It infuses and offers multiple spray orifices on the side wall of mud nozzle, since the emission direction and mud of spray orifice are infusing the flowing in mud nozzle Direction is perpendicular, therefore will cause certain flow velocity loss when mud sprays, and can not thoroughly prevent from generating mud cake on fish tail knife, And it is easy formation the overstocked of mud inside nozzle tip and in turn results in blocking.
Summary of the invention
The shield machine fish tail knife slip-casting mud good and with long service life the object of the present invention is to provide a kind of slip fluidity Mouth.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of shield machine fish tail knife slip-casting mud mouth, it wrap Installing pipe is included, the installation inside pipe wall has the erecting bed of annular, and the slip-casting mud mouth further 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 are divided into multiple groups, centered on main aperture infall described in multiple groups, 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 outward by center.
Optimization, the slip-casting mud mouth further include will be infused by bolt mud overhead gage be pressed on baffle pressing plate on erecting bed, The note mud lower baffle plate and note mud washer being pressed between the note mud overhead gage and the erecting bed, the note mud lower baffle plate middle part are opened Equipped with note mud mouth and its be located at the note mud overhead gage and infuse mud washer between, the baffle pressing plate is pressed on the note mud overhead gage Top and its middle part offer note 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, arranges in decussation.
Further, the cross section of the main aperture is successively decreased in isosceles trapezoid and area by center outward, on the note mud The lower end surface of baffle is equipped with right-angled intersection connected in star, the center of groove be the center of main aperture infall, recess width and depth by Center is successively decreased to four ends, and two waists of main aperture trapezoidal cross-section are located on the side of groove.
Due to the above technical solutions, the present invention has the following advantages over the prior art: mud of the present invention is from note Mud overhead gage sprays, and directly infuses mud to the easily overstocked position of the formation soil body in the middle part of fish tail knife, can thoroughly prevent the soil body from overstocking and be formed Mud cake, and infuse position of opening and size on mud overhead gage with flow is consistent everywhere in installing pipe, not will cause flow velocity loss, There will not be extra pressure to note mud overhead gage, greatly improve the service life of note mud overhead gage.
Detailed description of the invention
Attached drawing 1 is the three-dimensional view of nozzle of the present invention;
Attached drawing 2 is the top view of nozzle of the present invention;
Attached drawing 3 is the A-A cross-sectional view of attached drawing 2;
Attached drawing 4 is the three-dimensional view for infusing mud overhead gage.
Specific embodiment
The invention will be further described for embodiment shown in reference to the accompanying drawing.
Slip-casting mud mouth as shown in Figure 1, 2, 3 includes the installing pipe for the erecting bed that inner wall has annular, is installed on the installation On platform and offers the note mud overhead gages 7 in multiple note mud holes, note mud overhead gage 7 is pressed on by baffle on erecting bed by bolt 14 Pressing plate 8 is pressed on the note mud lower baffle plate 9 infused between mud overhead gage 7 and the erecting bed and infuses mud washer 10, under the note mud Note mud mouth is offered in the middle part of baffle 9 and it is located between the note mud overhead gage 7 and note mud washer 10, and note mud washer 10 is no stone Cotton pad piece, the baffle pressing plate 8 is pressed on 7 top of note mud overhead gage 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 it is two groups that the main aperture 11, which is divided to, is arranged in decussation Cloth, the secondary orifices 12 are uniformly distributed on the note mud overhead gage 7.Centered on 11 infall of main aperture described in two groups, the main aperture 11 cross section is successively decreased in isosceles trapezoid and area by center outward, and the lower end surface of the note mud overhead gage 7 is handed over equipped with cross Fork-shaped groove, the center of groove are the center of 11 infall of main aperture, and recess width and depth are successively decreased from center to four ends, main Two waists of 11 trapezoidal cross-section of hole are located on the side of groove, can by the design that width and depth are successively decreased around from center Pressure to guarantee slurry injection mud overhead gage 7 is uniform, will not cause to infuse the deformation of mud overhead gage 7 because of long-time service, eliminate The problem of needing to frequently replace note mud overhead gage 7 in the past.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
