Exploiting and crushing head structure for mining and tunneling equipment

Abstract

The invention provides an exploiting and crushing head structure for mining and tunneling equipment. The exploiting and crushing head structure comprises a small tunneling machine base body. An expanding hole is formed in the redundancy space portion of the surface of a cutter disc of the top of the small tunneling machine base body. An independent drilling head is connected and fixedly installedon the surface of the cutter disc of the top of the small tunneling machine base body through the expanding hole. Embedded water pumps are connected and fixedly installed in the two sides of a machinebody of the small tunneling machine base body through structures like screws. Pipelines are connected to the exteriors of the embedded water pumps. By arranging the embedded water pumps and the expanding hole, the structure solves the problems that simple fine adjustment cannot be carried out on the front end of an exploiting and crushing head structure of existing mining and tunneling equipmentconveniently according to the subtle difference of the state of an actual tunneling tunnel to meet the requirement of the test soil structure, meanwhile, after the tunnel is excavated, water is seepedinto a soil layer easily, an existing water pump water pipe structure seeps water to the tunnel slightly, and theadaptabilitytothe irregular plane in the tunnel is poor.

Description

technical field [0001] The invention belongs to the technical field of crushing head structure of mining equipment, and more specifically relates to the mining crushing head structure of mining tunneling equipment. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of shield tunneling is the "shield" (referring to the supporting segment) of the tunnel constructed (laid) by the roadheader while excavating, which is different from the open construction method. Internationally, the generalized shield machine can also be used in rock formations, but it is different from the open (non-shield method) tunnel boring machine. In our country, it is customary to call the tunnel boring machine used in soft soil formations (narrow sense) shield machine, and the one used in rock formations is called (narrow sense) TBM. According to the working principle, the shield machine is generally divided into hand-excavate...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a mining crushing head structure of mining excavation equipment, to solve the problem that the front end of the existing mining excavation equipment mining crushing head structure cannot be easily adjusted according to the subtle gap of the actual state of the tunnel. Fine-tuning to meet the needs of a more experimental soil structure. At the same time, after the tunnel is excavated, the soil layer is prone to water seepage. The existing water pump pipe structure has poor adaptability to the slight water seepage of the tunnel and the irregular plane inside the tunnel.
