A drilling and bursting heading machine, comprising a cantilever type heading machine (2), characterized by further comprising a drilling and bursting device (1), an angle control device and a forward-backward telescopic device, wherein the drilling and bursting device (1) is mounted on a forward-backward moving component of the forward-backward telescopic device by means of the angle control device, and the forward-backward telescopic device is mounted on the cantilever type heading machine (2);

• the drilling and bursting device (1) comprises a fixing support (1-20), a rock drill component and a bursting component, wherein the rock drill component and the bursting component are fixedly mounted on the fixing support (1-20) respectively;
• the rock drill component comprises a connecting base I (1-21), a slide rail I (1-22-1), a positioning guide plate I (1-22-2), a telescopic drive mechanism, a rock drill (1-24-1), a drill rod (1-24-2) and a slide block I (1-24-3);
• the slide rail I (1-22-1) is arranged in the forward-backward direction via the connecting base I (1-21) and fixedly mounted on the fixing support (1-20);
• the positioning guide plate I (1-22-2) is erected at a front end of the slide rail I (1-22-1), and provided with a guiding hole matched with the drill rod (1-24-2) in size;
• the drill rod (1-24-2) penetrates through the guiding hole of the positioning guide plate I (1-22-2) and is erected on the positioning guide plate I (1-22-2), and is mounted on the rock drill (1-24-1) in a manner of facing forward;
• the rock drill (1-24-1) is erected on the slide rail I (1-22-1) via the slide block I (1-24-3) fixedly mounted and connected to the rock drill (1-24-1) and matched with the slide rail I (1-22-1);
• the telescopic drive mechanism is mounted on the slide rail I (1-22-1) and connected with the rock drill (1-24-1);
• the bursting component comprises a connecting base II (1-26), a slide rail II (1-27-1), a positioning guide plate II (1-27-2), a telescopic drive mechanism, a slide block II (1-30-1) and a bursting device (1-30-2);
• the slide rail II (1-27-1) is arranged in the forward-backward direction via the connecting base II (1-26) and fixedly mounted on the fixing support (1-20);
• the positioning guide plate II (1-27-2) is erected at a front end of the slide rail II (1-27-1), and provided with a guiding hole matched with the outer diameter of a wedge jacking block of the bursting device (1-30-2);
• the wedge jacking block of the bursting device (1-30-2) penetrates through the positioning hole of the positioning guide plate II (1-27-2) and is erected on the positioning guide plate II (1-27-2), and is mounted on the bursting device (1-30-2) in a manner of facing forward;
• the bursting device (1-30-2) is erected on the slide rail II (1-27-1) via the slide block II (1-30-1) fixedly mounted and connected to the bursting device (1-30-2) and matched with the slide rail II (1-27-1);
• the telescopic drive mechanism is mounted on the slide rail II (1-27-1) and connected with the bursting device (1-30-2);
• the angle control device comprises a mounting base (1-15), an auxiliary rotary hydraulic motor (1-14), an adjustment hydraulic cylinder (1-13) and a main rotary hydraulic motor (1-12);
• a top end of the mounting base (1-15) is connected with the bottom of the fixing support (1-20), and a bottom end of the mounting base (1-15) is fixedly connected with an output shaft of the auxiliary rotary hydraulic motor (1-14);
• one end of a shell of the auxiliary rotary hydraulic motor (1-14) is articulated with one end of a shell of the main rotary hydraulic motor (1-12), and the other end of the shell of the auxiliary rotary hydraulic motor (1-14) is connected with the other end of the shell of the main rotary hydraulic motor (1-12) via the adjustment hydraulic cylinder (1-13);
• an output shaft of the main rotary hydraulic motor (1-12) is fixedly connected with the forward-backward moving component of the forward-backward telescopic device;
• when the forward-backward moving component of the forward-backward telescopic device completely extends out, the distance from a front end of the drilling and bursting device (1) to a working plane is shorter than the distance from a front end of a cutting head of the cantilever type heading machine (2) to the working plane.
