The invention provides a square mixing drilling machine. During work, an arm lever provides the pressure for trip-in; two drill bits mix cement slurry injected by a slurry injection device and soil during rotation; a bent cutter A, a plurality of rake teeth on the lower portion of the bent cutter A, a bent cutter B and a plurality of rake teeth on the lower portion of the bent cutter B mix soil between square and roundness during synchronous reverse-direction swing; thus square cement and soil piles are formed.
