Bin outer jaw type crusher

Abstract

The invention provides a bin outer jaw type crusher which comprises a stone storing box. A slurry input pipe is fixed to the front portion of the stone storing box. A stone storing area, at least onecrushing mechanism and a filtering mechanism are arranged in the stone storing box. The crushing mechanisms are arranged between the stone storing area and the filtering mechanism. The upper portionsof the crushing mechanisms are fixedly connected with the upper portion of the stone storing box. The filtering mechanism is fixedly arranged between the crushing mechanisms and a discharging mechanism. The filtering mechanism is fixedly connected with the stone storing box. The discharging mechanism is fixedly arranged on the rear portion of the stone storing box. The discharging mechanism and the slurry input pipe communicate with the stone storing area. According to the crusher, excavated stones are crushed and screened, discharging delay or blocking of a slurry discharging pump and a mud pipeline is avoided, and the slag discharging efficiency of a shield tunneling machine is improved.

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
