Self-propelled automatically targeting precise pesticide spraying machine

The invention discloses a self-propelled automatically targeting precise pesticide spraying machine, which comprises a walking device, wherein the rear end on the top of the walking device is provided with a pesticide spraying device, and the front end on the top of the walking device is provided with an ultrasonic detector; solenoid valves on a pipeline of the pesticide spraying device are connected to an embedded control platform; the ultrasonic detector mainly comprises an ultrasonic sensor; detection signal output of the ultrasonic detector is connected to the embedded control platform; the self-propelled automatically targeting precise pesticide spraying machine also can comprise a pesticide spraying signal detection control device; the self-propelled automatically targeting precise pesticide spraying machine comprises the solenoid valves, velocity sensors, a flow sensor, a pressure sensor and an electric ball valve; and the embedded control platform integrate signals of the sensors to control the on/off of the solenoid valves. The self-propelled automatically targeting precise pesticide spraying machine can automatically detect whether fruit trees are present in front of the machine and automatically spray a pesticide in a targeted way according to shapes of the fruit trees, so that the utilization rate of the liquid medicine is improved, the harm of the chemical pesticide to the safety of an operator is reduced and the pollution of the pesticide to the environment is reduced.
