The invention discloses an automatic monkey simulation spraying machine, and belongs to the field of gardening machinery. The automatic monkey simulation spraying machine comprises a monkey body, an upper limb, a lower limb and a tail, wherein the monkey body is connected with the upper limb, the lower limb and the tail and comprises a body, a lower limb steering engine room, a lower limb steering engine, a lower limb steering engine output shaft, a first lead, a central controller, a second lead, an upper limb steering engine room, an upper limb steering engine, an upper limb steering engine output shaft, a water tank, a head, an eye-shaped ultrasonic sensor, a third lead, an ear-shaped illuminating lamp, an illuminating lamp signal wire, an ultrasonic sensor signal wire, a thin water pipe and a tail fixing room. The automatic monkey simulation spraying machine has the advantages that the steering engines control swing of the upper limb and the lower limb to achieve the function of simulating a monkey climbing trees, and then the tail is controlled by the steering engines to achieve plant watering effects.
