Abstract

The invention discloses a round-corner trapezoidal tunnel excavator. The round-corner trapezoidal tunnel excavator is characterized in that a speed reducer I, a speed reducer II, a speed reducer III, a speed reducer IV and a speed reducer V are respectively used for driving a corresponding drill bit arranged at the rear end through a corresponding drill rod arranged at the rear end during a rotating process; five rotating shafts during rotating respectively drive stirring blades to rotate through stirring arms; the five drill bits during rotating are used for cutting soil bodies behind the five drill bits; the stirring blades on the five rotating shafts are used for cutting soil on four edges of holes which are similar to trapezoidal shapes; the cut soil is conveyed into a conveying device and is conveyed outside a tunnel through the conveying device; a round-corner trapezoidal tunnel is formed by the round-corner trapezoidal tunnel excavator during a propelling process.
