Problems solved by technology

The telescoping mechanism connected to the auxiliary cutter head of the above patent can change the cutting diameter of the cutter head, and is suitable for the needs of tunnels with various diameters. Although the number of cutters can be increased to a certain extent, the method of increasing the area of ​​the cutter head is still used. Increase the number of knives. In actual engineering applications, if you want to increase the number of knives during the excavation process using the above-mentioned shield machine cutter head, the excavation area will also increase accordingly, which is not very practical.

Abstract

The application relates to the technical field of construction machinery, and discloses a composite shield tunneling machine cutter head, which comprises a main cutter head. Cutter grooves are arranged in the main cutter head. A side cutter is arranged in each cutter groove. Scrapers are further disposed on the main cutter head. The main cutter head is further provided with a sub cutter head thereon. The sub cutter head is hollow inside, and is provided with a telescopic hob mechanism. The telescopic hob mechanism comprises hob bodies and first and second gears disposed on left and right sidesof each hob body. Racks are disposed on the left and right sides of each hob body. The racks are respectively engaged with the first and second gears. The sub cutter head is provided with cutter bodyoutlets corresponding to the hob bodies. The top of each hob body is provided with a closing plate that closes the corresponding cutter body outlet. The application can increase the number of tools on the cutter head according to requirements without increasing the area of the main cutter head, thereby improving the efficiency of crushing and excavation.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a composite shield machine cutterhead. Background technique [0002] The shield machine is a tunnel boring machine using the shield method. It is mostly used in construction projects such as subways, tunnels, and pipelines. Because of its high degree of automation, it has the characteristics of fast construction speed and high safety performance. , there is no need to demolish the ground buildings in a large area, there is no noise during construction, and it will not affect the normal life of the surrounding residents. When the shield machine is working, it mainly uses the cutter on the cutter head at the front end of the body to break and excavate the surrounding soil or rocks, so the cutter head is one of the core components of the shield machine. The number of knives on the cutter head is often fixed, and it is impossible to increase the number of knives in re...
