Abstract

The invention discloses a cutting mechanism of a tunneller, which comprises a cutting head (1), a telescopic part (2) and a floating seal frame (3), wherein the floating seal frame (3) is connected between the cutting head (1) and the telescopic part (2); a cavity (5) is arranged between the cutting head (1) and the floating seal frame (3), and the outer end part of the cavity (5) is communicated with the air; the cutting mechanism further comprises a dustproof mechanism (4); the dustproof mechanism (4) comprises an air compressor (41) and a ventilation pipe (42) which are connected with each other; the air inlet end of the ventilation pipe (42) is communicated with the air outlet end of the air compressor (41), and the air outlet end of the ventilation pipe (42) is communicated with the inside of the cavity (5). The cutting mechanism has the continuous tightness. The invention further discloses a tunneller which comprises a cantilever supporting mechanism and the cutting mechanism, wherein the cutting mechanism is supported on the cantilever supporting mechanism. The tunneller has the same technical effect.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a cutting mechanism for a roadheader. The present invention also relates to a boring machine comprising the above-mentioned cutting mechanism. Background technique [0002] Mining machinery is directly used for mineral mining and enrichment operations, mainly including mine mining machinery, mine lifting and transportation equipment, and mine three-dimensional machinery. [0003] The roadheader is the most important type of mining machinery, with flexible working methods and good adaptability. It is mainly used for roadway excavation in mines and underground engineering. It can simultaneously realize functions such as crushing coal and rock, loading and transporting, mobilizing and walking, and spraying and dust removal. . At present, the roadheaders developed and produced at home and abroad can be divided into two categories according to the different working methods ...
