Реферат: Disclosed is an eccentric hob type tunneling machine capable of breaking rock according to a predetermined path without affecting supporting work, essentially consisting of a crawler walking mechanism, a rack, a hydraulic pump station, a power box, a sliding guide rail base, a propulsion cylinder I, a sliding seat, a transmission box, hydraulic motors, a hob arm rotating and sliding device, a hob arm, a low-speed high-torque motor, an eccentric disc-shaped hob, a control center, a loading device, a conveying device, a temporary supporting device, and an auxiliary work platform. The present invention is simple, compact and reliable in structure and convenient to assemble and disassemble, makes full use of low tensile strength characteristics of hard rock, and has strong rock breaking capability and high efficiency. The route of breaking rock with a hob can be adjusted according to different sections, and thus the section adaptability is flexible. The disc-shaped hob has a small cutting-based rock breaking load, high performance and high efficiency, and the hob rotates eccentrically, so that the hob can achieve the effect of breaking rock by vibration cutting, thereby further improving the cutting-based rock breaking performance of the hob.
