The invention provides stirring pile construction equipment with novel stirring blades. A drill rod is arranged on a pile frame, drill rod blades are arranged on the lower portion of the drill rod, and the stirring blades are arranged between the drill rod blades and connected with the drill rod through a rotatable shaft sleeve. During construction, the drill rod drills downwards, after being inserted into soil, the stirring blades do not rotate under the action of resistance, the drill rod blades continue to rotate under driving of the drill rod, the stirring blades and the drill rod blades move relatively to generate a cutting effect, and undisturbed soil is stirred into fine particles to be fully mixed with a curing agent; and when bonding soil blocks are bonded to the drill rod blades and the roots of the drill rod blades, the stirring blades and the drill rod blades move mutually, the bonding soil blocks of the drill rod blades can be removed, and the phenomenon that the blades are wrapped by the soil bl
