Abstract

See full text

A vibrating type hard rock cutting mechanism with a function of directional high-speed abrasive jet advanced slitting includes a disc-shaped hob, a cutting main shaft and a valve plate. When the vibrating type hard rock cutting mechanism works, an outlet of a high-pressure abrasive jet generating system is communicated to a cutting mechanism abrasive jet inlet. An abrasive jet enters an abrasive jet nozzle through flow channels in the valve plate, the cutting main shaft and the disc-shaped hob and forms a directional high-speed abrasive jet. The cutting main shaft is directly driven to rotate by an axial permanent magnet motor. The cutting mechanism enables the disc-shaped hob to vibrate under the action of a vibration motor. A macro crack is formed on a rock mass by rotating the abrasive jet. The rotating disc-shaped hob can be wedged into the formed crack in a vibration manner by swinging the cutting mechanism.
