Problems solved by technology

The cutting knives arranged on the cutter head are cut and protruded in the plane or in the middle during the excavation process. The excavation around the tunnel wall is carried out on the same plane as the surface excavation in other parts. Each cutter bears a large force, resulting in a large demand for power and a large energy loss

Embodiment Construction

[0032] specific implementation plan

[0033] Such as Figure 1 to Figure 8 As shown, a shield machine with a ring trimming knife includes a body 8, a transmission shaft 4, an excavation box 5, a conveyor belt 7, a knife holder shell 2 and a cutting knife 1. Since the present invention is an improvement on the traditional shield machine, the machine body, the drive shaft that drives the tool holder shell and the cutter head 22 and the multiple cutting knives on it, the bearing pair 3, and the excavation box that receives the cutting dregs at the rear side of the cutter head And the excavation opening 6 that communicates with the conveyor belt, the conveyor belt support frame 11 etc. are traditional shield machine structures, so no longer repeat.

[0034] The present invention is provided with several ring edge cutters 9 at intervals on the front end side of the tool holder housing; or several ring edge cutters are arranged at intervals on the side of the cutter head; Several ...

Abstract

The invention belongs to a shield machine with a ring trimming knife. Including machine body, transmission shaft, excavation box, conveyor belt, tool holder housing and cutting knife. The side of the cutter head is provided with several ring edge cutters at intervals; or the front side of the knife holder shell and the side of the cutter head are provided with several ring edge cutters at intervals. Each ring edge cutter is arched, and the outer end of each ring edge cutter is provided with knife teeth, and the inner part of the ring edge cutter is provided at a distance from the side edge of the knife holder shell or cutter head. used bolt holes. The length of the outer end of each ring edge cutter protruding from the outer periphery of the cutter head is greater than the length of the cutting knife on the cutter head extending out of the outer periphery of the cutter head. The invention utilizes the ring edge cutter to cut and separate the strata around the tunnel wall in advance, and can achieve an ideal effect of cutting the tunnel wall surface, and has the advantages of simple structure, convenient use, good cutting effect, low construction cost, energy saving and good use effect.

Description

technical field [0001] The invention belongs to a shield machine with a ring trimming knife. Background technique [0002] At present, the shield machine relies on the cutter head on the front face of the tool holder shell and the cutting knives and cutting tools configured on it to complete the cutting and excavation of the underground construction stratum to process the tunnel required for laying the pipeline, and then the laid pipeline wall The block is pushed against the back of the shield machine, and is pushed into the tunnel processed by the shield machine through the pipe jacking machine located at the back of the pipe pass, thereby completing the laying of the tunnel pipe wall. [0003] Most of the cutting knives arranged on the cutter head of the shield machine are located on the same cutting plane, and there are also cutting knives protruding from the middle of the cutter head. Ideally, the tunnel wall surface cut and excavated by the cutting knives on the cutter...
