Abstract

The invention provides a conical cutterhead and a heading machine, and relates to the technical field of engineering tunnel equipment. The conical cutterhead comprises a cutterhead body; the cutterhead body is in a frustum shape; a plurality of hobs are rotatably installed on the cone top and the side wall of the cutterhead body; and a plurality of cutting teeth are further installed on the side wall of the cutterhead body. The conical cutterhead and the heading machine provided by the invention have good rock breaking efficiency on soft rocks and hard rocks.

Description

technical field [0001] The invention relates to the technical field of engineering tunnel equipment, in particular to a conical cutterhead and a boring machine. Background technique [0002] Tunneling machine is a kind of comprehensive equipment that performs continuous operations by mechanically crushing rocks, removing slag and supporting, and is widely used in hydropower, railway, and subway tunnel projects. At present, the cantilever type roadheader adopts a pick cutter for the excavation cutter head, and the pick cutter has high excavation efficiency in soft soil and soft rock formation, but the excavation efficiency is extremely low when encountering hard rock formation. Especially when the rock hardness is greater than the cutting capacity of the pick, it is necessary to stop using the roadheader and replace it with a cutter head equipped with a hob cutter. It not only increases the construction process and construction difficulty of the excavation construction, but ...
