Abstract
The invention provides an excavator for a square tunnel with round corners. Drill stems at the left ends of a first gear case, a second gear case, a third gear case, a fourth gear case and a fifth gear case drive drill bits at the left ends of the drill stems to rotate when the first gear case, the second gear case, the third gear case, the fourth gear case and the fifth gear case are in operation. Four first transmission shafts drive stirring rods to rotate around the first transmission shafts through movable arms during rotation respectively. The five drill bits cut a soil body on the left side of the drill bits during rotation. The stirring rods on the four first transmission shafts cut soil of four edges forming an approximate square shape during rotation, and soil which is cut off is conveyed into a conveying device and conveyed out of the tunnel through the conveying device. The square tunnel with round corners is formed by the excavator in the advancing process.
