A kind of outside jaw crusher

Abstract

The invention proposes an out-silo jaw crusher, which includes a stone storage box, the front part of the stone storage box is fixedly provided with a slurry feeding pipe, and the interior of the stone storage box is provided with a stone storage area, at least one crushing mechanism and a filter The crushing mechanism is arranged between the stone storage area and the filtering mechanism, and the upper part of the crushing mechanism is fixedly connected with the upper part of the stone storage box; the filtering mechanism is fixedly arranged between the crushing mechanism and the discharge mechanism, and the filtering mechanism is connected with the storage mechanism The stone box is fixedly connected; the discharge mechanism is fixedly arranged at the rear of the stone storage box, and the discharge mechanism and the slurry feeding pipe are both communicated with the stone storage area. By crushing and screening the excavated stones, the invention avoids the stagnation or blockage of the slurry pump and the slurry pipeline, and improves the slag discharge efficiency of the shield machine.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to a jaw crusher outside a warehouse. Background technique [0002] With the rapid development of industrial technology, mechanized tunnel construction technology is becoming more and more mature. The shield machine has the advantages of precise control, high efficiency and safety, reliable quality, and environmental friendliness. It is widely used in projects such as subway tunnels, highway tunnels, river-crossing tunnels, cross-sea tunnels, and water diversion and sewage tunnels. [0003] At present, there are mainly two types of shield machines: earth pressure shield machine and mud-water shield machine. Among them, the mud-water shield machine relies on the slurry discharge pump and mud pipeline to discharge slag. The slag outlet is equipped with a crusher. There are two ways to arrange the crusher on the shield machine: outside the warehouse ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problem that the existing crushers cannot satisfy the crushing of large-sized stones, the present invention proposes a jaw crusher outside the warehouse, which solves the problem of the discharge pump and mud pipe caused by large-sized stones during the construction of the shield machine. The problem of stagnation, blockage and wear has improved the construction progress of the tunnel
