Modularly assembled full-automatic tunneling and rock-breaking robots and working methods thereof

A modularly assembled full-automatic tunneling and rock-breaking robot, comprising a robot main body module, and stress advance relief modules and rock-breaking modules arranged on the robot main body module;

• wherein
• each of the stress advance relief modules includes a stress advance relief module housing, a drill bit moving notch, a stress advance relief module base, a stress advance relief module telescopic mechanism, a stress advance relief module guide rail, a stress advance relief module drilling power mechanism, a stress advance relief module drill rod, a stress advance relief module drill bit, and a stress advance relief module sliding mechanism;
• the stress advance relief module housing is mounted on the stress advance relief module base by the stress advance relief module telescopic mechanism, the drill bit moving notch is opened on one side of the stress advance relief module housing, the stress advance relief module guide rail, the stress advance relief module drilling power mechanism, the stress advance relief module drill rod, the stress advance relief module drill bit, and the stress advance relief module sliding mechanism are all arranged inside the stress advance relief module housing;
• and
• the stress advance relief module drilling power mechanism, the stress advance relief module drill rod, and the stress advance relief module drill bit are assembled to form a stress advance relief module drilling assembly, the stress advance relief module drilling assembly is arranged on the stress advance relief module guide rail, the stress advance relief module guide rail is pushed by the stress advance relief module sliding mechanism to move along a length direction of the drill bit moving notch.
