A kind of Novel anti-blockage cutterhead sediment improvement agent spout device, including spout ring, be arranged in the middle part of spout ring
Fagging and the elastic packing plate being pressed on by pressure ring on spout ring, the side of middle supporting plate is boss pyramidal structure, and in support
Multiple modifying agent spouts are circumferentially uniformly offered on plate, the inner surface of described elastic packing plate is to be fitted with middle supporting plate matching
The cone structure of sealing, and elastic packing plate includes the complementary Sectorial sealplate one and Sectorial sealplate two of matching laminating.
It is bolted between spout ring and pressure ring, the outer rim matching pressure of described elastic packing plate sets spout ring with pressure
Between ring.
The central angle alpha of described Sectorial sealplate one and the central angle β sums of Sectorial sealplate two are 360 °, and 90 ° of ＜ α
180 ° or 90 ° 180 ° of ＜ 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 above-mentioned technical proposal, acquired beneficial effect is：
The encapsulant of the utility model spout elastic packing plate is polyurethane, improves the tear resistance of spout sealing；
Its spout ring is designed for boss cone structure, and spout elastic packing plate is designed for the conical surface, effectively reduces spout seal operation shape
