Abstract
The invention belongs to the technical field of tunneling shield. The nozzle device comprises a nozzle ring, a middle support plate placed at the center of the nozzle ring and an elastic sealing plate placed pressingly on the nozzle ring through a press ring. The side of the middle support plate is a convex conical structure. A plurality of the modifier agent ejection nozzles are evenly arranged on the middle support plate in a circle. The inner surface of the elastic sealing plate is a conical surface structure matching and adhering to the middle support plate. The elastic sealing plate comprises two fan shape sealing plates number 1 and number 2 matching with the elastic sealing plate. The sealing material of the elastic sealing plate is polyurethane which enhances the anti-tearing capacity of the ejection nozzle sealing. The nozzle ring is applies the design of the convex conical surface structure. The elastic sealing plate at the nozzle applies the conical surface design which can effectively reduce the elastic deformation in the working condition of the ejection nozzle, enhances the returning force and prolongs the service life of the sealing.

Background technology
With communications and transportation, water conservancy, urbanization Tunnel Engineering fast development, shield-tunneling construction applies subterranean tunnel construction
More and more extensive in work, due to the complicated variety of geology, simultaneously in order to increase the service life of knife disc tool, sediment improvement
Effect ever more important, and the sediment improvement agent orifice design of routine, rubber seal screen resilience is not enough and in dregs easy to wear or
Tear, causes seal failure, leads to sediment improvement agent spout to block.For this reason, we are badly in need of to cutterhead sediment improvement agent spout
Structure is optimized design, to reduce the risk of the blocking of sediment improvement agent spout.
Content of the invention
The purpose of the present invention is for above-mentioned problem and shortage, provides a kind of reasonable in design, compact, sealing
Performance and the good Novel anti-blockage cutterhead sediment improvement agent spout device of rebound performance.
Adopted the technical scheme that by reaching above-mentioned purpose：
A kind of Novel anti-blockage cutterhead sediment improvement agent spout device, including spout ring, be arranged on middle supporting plate in the middle part of spout ring,
With the elastic packing plate being pressed on by pressure ring on spout ring, the side of middle supporting plate is boss pyramidal structure, and on middle supporting plate
Circumferentially uniformly offer multiple modifying agent spouts, the inner surface of described elastic packing plate is to mate gluing, sealing with middle supporting plate
Cone structure, and elastic packing plate includes mating the complementary Sectorial sealplate one of laminating and Sectorial sealplate two.
It is bolted between spout ring and pressure ring, the outer rim coupling pressure of described elastic packing plate sets spout ring and pressure
Between ring.
The center of circle angle beta sum of the described central angle alpha of Sectorial sealplate one and Sectorial sealplate two is 360 °, and 90 ° of ＜ α
180 ° of 180 ° or 90 ° ＜ β ＜ of ＜.
The material of described elastic packing plate is polyurethane.
Under sediment improvement agent injection state, the axial outer end portion of described pressure ring is high compared with elastic packing plate outer end.
Using technique scheme, acquired beneficial effect is：
The encapsulant of spout elastic packing plate of the present invention is polyurethane, improves the tear resistance of spout sealing；Its spout ring
For the design of boss cone structure, spout elastic packing plate designs for the conical surface, effectively reduces bullet during spout seal operation state
Property deformation, improves its screen resilience, increased the service life of this sealing.
The elastic packing plate of nozzle of the present invention and spout ring are conical design, when stopping changes to face injection dregs
When good dose, the elastic packing plate of spout is fitted closely with the middle supporting plate of spout ring, can effectively prevent dregs from entering spout, play
The effect of sealing；Cutterhead sediment improvement spout of the present invention, reduces the probability of spout seal failure, can effectively prevent cutterhead
The blocking of sediment improvement spout.
