Embodiment 1

[0021] Embodiment 1, the electrode 5 is moved in the electrode groove 4 by loading the piston rod 3 through the actuator; according to the pressure of the nozzle, the loading force of the actuator is adjusted to control the moving distance of the electrode 5 in the electrode groove 4. The actuator can be an electric push rod or a straight line. According to the pressure of the nozzle, the controller controls the external force applied by the electric push rod or the straight line. The distance that the electrode 5 moves in the electrode groove 4 is proportional to the pressure of the nozzle.

Embodiment 2

[0022] Embodiment 2, the electrode tank 4 communicates with the liquid inlet chamber of the spray head 8 through the pressure hole 9, and the piston rod 3 is moved in the electrode tank 4 by hydraulic pressure; the other end of the electrode 5 is equipped with a spring 6 to The distance that the electrode 5 moves in the electrode groove 4 is proportional to the pressure of the shower head. When the liquid pressure is small, the spring 6 keeps the electrode 3 close to the nozzle outlet, and when the liquid pressure is high, the piston rod 3 will push the electrode 3 to overcome the elastic force of the spring 6, so that the electrode 3 moves down to far away from the nozzle outlet Location.

[0023] work process:

[0024] Install the nozzle required for spraying in the nozzle seat 1, and determine the electrode 5 and spring 6 according to the selected nozzle and the set spray pressure as a reference; extend the wire from the wire hole 2 into the electrode slot 4, and connect t...

Abstract

The invention provides a fan-shaped electrostatic induction atomizing spray head with an automatically adjustable electrode, which comprises a spray head and a spray head seat, the spray head is arranged on the spray head seat, and electrode devices capable of moving along the spraying direction of a nozzle are uniformly distributed in the spray head seat near the spray head and are used for enabling spray droplets to inductively charge. The electrode device comprises an electrode and a piston rod; a plurality of electrode grooves are evenly distributed near the sprayer seat with the sprayer as the center, an electrode is placed in any electrode groove, one end of the electrode is connected with a piston rod, and the piston rod is loaded through external force to enable the electrode to move in the electrode groove. According to the invention, the position of the electrode can be automatically adjusted under the condition that the spray pressure is changed.

Description

technical field [0001] The invention relates to the technical field of electrostatic atomization and spraying, in particular to a fan-shaped electrostatic induction atomization nozzle whose electrodes can be automatically adjusted. Background technique [0002] Electrostatic spraying is a high-efficiency plant protection spraying technology, which can improve the uniformity of liquid deposition and distribution and the adhesion rate on the back of plant targets. Studies have shown that the best charging effect can be obtained only when the sensing electrodes are arranged at a suitable position. During the actual spraying operation, the spraying pressure will be affected by factors such as mechanical vibration, which will lead to pressure instability, and the optimal charging position corresponding to different pressures is different. But existing induction electrostatic nozzle, the position of its induction electrode is all fixed, for example, in the induction type electros...
