description The invention relates to the technical field of constructional engineering equipment, and particularly discloses a core drilling soil taking machine which comprises a driver, a drill rod and spiral blades, the driver is used for driving the drill rod to rotate, the spiral blades are fixedly connected to the drill rod and comprise the main spiral blade and the auxiliary spiral blade, the auxiliary spiral blade is a variable-diameter spiral blade with the outer diameter gradually changing, and the main spiral blade is fixedly connected to the drill rod. The maximum outer diameter of the auxiliary spiral blade is equal to the outer diameter of the main spiral blade, the end, away from the main spiral blade, of the auxiliary spiral blade is close to the end of the drill rod, and the pitch of the auxiliary spiral blade is smaller than that of the main spiral blade. According to the scheme, the problems that in the existing pipe pile soil digging process, the soil digging efficiency of a shovel is low, and an opera
