Abstract

The invention discloses a pneumatic atomizing static electricity spraying head and a mist spraying system. An air compressor is connected with a gas inlet in the top end of a gas jet nozzle through apipeline. A liquid input pipe is installed in an oblique installing hole in the gas jet nozzle. The top end of an elevating medicine box is connected with a pump through a pipeline. The pump is connected with an outlet in the bottom of a liquid medicine box through a pipeline. An electrode base is fixedly installed in a center hole in the bottom of the gas jet nozzle. An electrode is installed onthe electrode base. A first copper pin is installed in an installing hole in the electrode base, and the tail portion of the first copper pin is connected with the electrode. A second copper pin is installed in an installing hole in the gas jet nozzle and passes through a through hole in the electrode base. A metal net is installed in a center hole of the electrode base and connected with the tailportion of the second copper pin. The two ends of a high-voltage power source are connected with the first copper pin and the second copper pin through wires correspondingly. The spraying head is simple in structure, stable and reliable, in comparison with traditional low-speed airflow assisting transportation, transportation time of charged mist drips is shortened greatly, and the liquid medicine deposition effect is improved.

Description

technical field [0001] The invention belongs to the technical field of pesticide spraying, and in particular relates to a pneumatic atomizing electrostatic spray head and a spraying system. Background technique [0002] Problems in the current industry: Electrostatic nozzles are mainly based on pressure atomization and inductive charging. Among them, 1) The particle size of the atomized droplets under the pressure of 0.3MPa is about 100-300 microns, which is difficult to atomize into smaller droplets, and the smaller droplets are conducive to the inductive charging process. 2) The direct charging method is the most direct and effective method to charge the liquid, but the direct charging method charges the entire spray system and even the entire sprayer. This requires the spray system to have good insulation, in case of electric leakage there is a safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a...
