Zusammenfassung:The invention discloses inclined drilling rotary spraying stirring pile planting equipment. Two slurry spraying openings are symmetrically formed in the ends of two slurry conveying pipes at a drill bit relative to the axis of the drill bit. At least one concentric positioning frame enabling the drill rod and the core pile to be concentric is arranged in the core pile; an arrowhead-shaped stirring blade with a wide upper part and a sharp lower part is fixed at the bottom end of the drill bit; the bottom end of the core pile is provided with a big-end-up conical structure used for sinking into a soil body. A tubular sliding rail sleeve is fixed to the bottom of the middle section of the inclined supporting frame, a tubular sliding rail is arranged in the tubular sliding rail sleeve in a sliding fit mode, a driving oil cylinder is arranged in the tubular sliding rail and the tubular sliding rail sleeve in a sleeved mode and extends out of the tubular sliding rail sleeve upwards, and the tail end of the driving
