The invention discloses a well digging drill, and belongs to tools for taking sediments or quicksand in a well pipe section of the bottom of a well out of the well. People always risk their lives to go down to the bottom of the well to dig the well when the phenomenon that well water is muddy or no water exists due to the fact that sediments or quicksand is generated occurs in the using process, then dug sediments or quicksand is pulled out through a rope, and therefore countless people are buried at the bottom of the well for digging well for drinking water. According to the well digging drill comprising a torsion bar 1, a transmission part 2, a well digging drill bit 3 and a noose 21 shown in the attached drawing, people just need to rotate the torsion bar on the ground and give downward force to the torsion rod, the transmission part transmits the force of the torsion rod to the well digging drill, the well digging drill bit is rotated at the bottom of the well and conducts downward drilling to enable sediments or quicksand in the well pipe section of the bottom of the well to enter a sand taking tank of the well digging drill bit, and the sediments or quicksand can be lifted up from the bottom of the well through the transmission part and/or a rope on the noose or the drill bit.
