A new type of anti-clogging cutter head dregs soil modifier nozzle device

Abstract

The invention belongs to the technical field of shield tunneling. A new type of anti-clogging cutter head dregs soil modifier nozzle device, including a nozzle ring, a center support plate arranged in the middle of the nozzle ring, and an elastic sealing plate set on the nozzle ring by pressing the pressure ring, the side of the center support plate is convex Conical structure, and a plurality of modifier nozzles are evenly distributed on the center support plate, the inner surface of the elastic sealing plate is a conical surface structure that matches and seals the center support plate, and the elastic sealing plate It includes matching and fitting complementary fan-shaped sealing plate 1 and fan-shaped sealing plate 2. The sealing material of the spout elastic sealing plate of the present invention is polyurethane, which improves the tear resistance of the spout seal; the spout ring is designed with a convex conical surface structure, and the spout elastic sealing plate is designed with a conical surface, which effectively reduces the working state of the spout sealing The elastic deformation at the time improves its resilience and increases the service life of the seal.

Description

technical field [0001] The invention belongs to the technical field of shield machine excavation, and in particular relates to a novel anti-clogging cutter head dregs soil modifier spout device. Background technique [0002] With the rapid development of transportation, water conservancy, and urbanization tunnel projects, shield construction is more and more widely used in the construction of underground tunnels. The role is becoming more and more important, and the conventional design of the nozzle of the soil modifier, the rubber seal has insufficient resilience and is easy to wear or tear in the soil, causing the seal to fail and cause the nozzle of the soil modifier to be blocked. Therefore, we urgently need to optimize the structure of the nozzle of the cutter head dregs modifier to reduce the risk of clogging of the dregs modifier nozzle. Contents of the invention [0003] The object of the present invention is to solve the above existing problems and deficiencies, ...
