Abstract
Disclosed is an L-shaped tunnel excavator. Each of a first transmission box, a second transmission box, a third transmission box and a fourth transmission box drives a drill bit at the front end thereof to rotate through a drill rod at the front end thereof during operation. Each first transmission shaft drives a stirring arm to rotate through a connecting arm thereon during rotation. Each drill bit cuts mud in the front thereof during rotation, the stirring arm on each first transmission shaft cuts an area, with the size being smaller than the diameter of each drill bit, between the two drill bits adjacent to the transmission shaft during rotation, the cut mud is conveyed to a conveying device, and the conveying device conveys the cut mud to a proper position. The L-shaped tunnel excavator forms a tunnel with an L-shaped section during excavation.
