Anchor drill uneven ground self-adaptation crawler chassis

An anchor drill uneven ground self-adaptation crawler chassis comprises vehicle frames, a left crawler frame and a right crawler frame, wherein the left crawler frame and the right crawler frame are connected between the vehicle frames. A left crawler wheel is connected onto the left crawler frame; a right crawler wheel is connected onto the right crawler frame; rotary shafts are connected between the left crawler frame and the right crawler frame; the vehicle frames are hinged onto the rotary shafts; a left hinged base and a right hinged base are fixedly connected to the inner side of the left crawler frame and the inner side of the right crawler frame; a left hinged lug and a right hinged lug are connected to two sides of each vehicle frame; a left oil cylinder is hinged between the left hinged base and the left hinged lug; and a right oil cylinder is hinged between the right hinged base and the right hinged lug. The crawler chassis is capable of conveniently adjusting the position of a machine frame and simultaneously adjusting the position of an anchor rod operating device corresponding to an anchor hole on the machine frame, thereby bringing great convenience for adjusting operation.
