Abstract

The invention provides a cutter of a comprehensive mechanized rock tunnel boring machine. The cutter mainly comprises a cutterhead, conical hobs, conical hob shafts, hob bearings and a hob shaft seat, wherein the hob shaft seat is installed on the cutterhead; the conical hob shafts and the hob bearings are arranged in the conical hobs; and the conical hob shafts are installed in the hob shaft seat. The cutter has the following beneficial effects: the cutter can be used for improving the mechanized construction level of rock tunnel boring in the mine, is an important work part of the rock tunnel boring machine in the mine, has a compact structure and working stability and reliability, can be used for substantially improving the development work efficiency to be about three times that of rock tunnel blasting boring, can cut rock strata with hardness higher than the grade 8, breaks through the big problem that the hard rocks can not be cut and is suitable for the rock tunnel boring machines in the mines in various sizes.

Description

technical field [0001] The invention belongs to underground development equipment of coal mines, and is suitable for cutting blades of comprehensive mechanized rock roadheading machines used for comprehensive mechanized development operations of underground rock roads in large, medium and small coal mines. Background technique [0002] In the field of coal mine development equipment technology, such as Chinese Patent Application No. 200820077065.6 discloses a "rock roadway excavation and support construction drilling rig" including a crawler walking part and a belt transport part, a temporary support and a raking rock breaking part, two The part of the roof bolt and cable anchor drilling rig that can be lifted and swung, the hydraulic pressure and the operating system. The equipment has three bases on the operating platform for fixing the oil cylinder, two of which are used to fix the roof bolt bolt and cable drilling rig, and one base is used to fix the temporary support an...
