Abstract

A rotary digging drill includes three disk drills arranged in ascending order of diameter, each with a cavity therein. The disk drill includes two circular ring seats arranged side by side, multiple toothed digging buckets disposed at peripheries of the two circular ring seats, and ring gear racks respectively disposed on inner sides of the two circular ring seats. Adjacent ones of the disk drills have the toothed digging buckets facing opposite directions, and the disk drills all rotate in a direction facing a large opening, enabling adjacent two of the three disk drills to rotate in opposite directions. The rotary digging drill further includes three disk drill supports that match the three disk drills in quantity and are configured to support and drive the three disk drills.
