Spraying system, control method and device and spraying equipment

Abstract

The invention discloses a spraying system, a control method and device and spraying equipment, and belongs to the technical field of spraying. The spraying system comprises a first control valve, a control assembly and a flow dividing pipe, wherein the flow dividing pipe is a three-way pipe; all end ports of the flow dividing pipe are respectively connected with the input end of the first controlvalve, a pressure pipeline and the spraying pipeline; when the first control valve is turned off, liquid conveyed by the pressure pipeline flows to the spraying pipeline through the flow dividing pipe, and a spraying nozzle obtains the liquid by the spraying pipeline to carry out spraying; and when the first control valve is turned on, as the pressure of the output end of the first control valve is very low, the liquid conveyed by the pressure pipeline automatically flows to the output end of the first control valve through the flow dividing pipe, the spraying nozzle stops spraying, and the output end of the first control valve enables the liquid to flow into a liquid storage container through a liquid discharge pipe. The invention can solve the problems that due to injection air flow in the spraying process, problems of increase of the fog drop drifting rate, increase of the off-target rate, liquid dropping and the like are caused, resulting in waste of water or medicine liquid, and the environment pollution is caused by floating and off-target of the medicine liquid.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a spraying system, a control method and device, and spraying equipment. Background technique [0002] At present, the spraying control method is mainly to continuously spray the target area. When the relative position of the nozzle and the target area is fixed, or the relative position of the nozzle and the target area stays for a long time, the nozzle will continue to spray the target area for a long time. The area is sprayed, because when the sprayed droplets move to the target area, the airflow generated by the ejection effect reaches the target area, and the airflow moves in different directions due to the obstruction of the target in the target area, and the continuous airflow continues to increase the airflow Therefore, most of the droplets miss the target and drift away with the airflow, which greatly reduces the deposition rate of the droplets and causes a waste of resou...
