The invention discloses a plant protection unmanned aerial vehicle which comprises a body, a plurality of supporting arms and a telescopic spray rod arranged on the body. The inner ends of the supporting arms are all arranged on the body. The supporting arms are provided with motors, and the motors are provided with rotary wings. A landing gear is arranged under the body, the outer ends of the supporting arms are fixed to a protective ring and are fixedly connected through the protective ring. The annular protective ring and an energy absorbing ring are arranged so that impact energy generated during collisions can be effectively absorbed and transmitted, and damage caused by collisions or falling to main parts of the unmanned aerial vehicle is effectively avoided; meanwhile, a buffering layer is arranged on the landing gear, and thus damage caused by too large impact force generated during landing to a aerial vehicle body is prevented.
