Mining crushing head structure of mining tunneling equipment

Abstract

The invention provides a mining crushing head structure of mining tunneling equipment, which includes a small shield machine base body; the redundant space part on the surface of the cutting cutter head on the top of the small shield machine base body is provided with expanded holes, and the top cutting blade of the small shield machine base body The surface of the disc is connected by expanding holes and fixedly installed with an independent drill bit; the inner sides of the base body of the small shield machine are connected by screws and other structures and fixedly installed with an embedded water pump; the outside of the embedded water pump is connected with a pipe. The setting of the embedded water pump and the expansion hole solves the problem that the front end of the mining crushing head structure of the existing mining excavation equipment cannot be easily fine-tuned according to the subtle differences in the actual tunneling conditions to achieve a more experimental soil structure. At the same time, after the tunnel is excavated, the soil layer is prone to water seepage, and the existing water pump pipe structure has poor adaptability to the slight water seepage of the tunnel and the irregular plane inside the tunnel.

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.
