Problems solved by technology

In addition, the existing electrostatic nozzles are all conical atomization modes. By adding a cylindrical electrode at the front end of the nozzle, the purpose of charging the droplets after spraying is achieved, but the cylindrical spray is not suitable for the boom sprayer. The symmetrical droplet distribution will cause repeated spraying of the operation object and waste of pesticides

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 , 2 , 3 and 4, the fan spray electrostatic spray head of the present invention includes overflow valve 1; Nozzle body 2; Screw head 3; Nozzle 4; Nozzle 5;

[0033] combine Figure 5 , 6 As shown in and 7, the overflow valve 1 and the nozzle body 2 are injection molded into one body, and the overflow valve 1 plays the role of adjusting the spray pressure of the nozzle and preventing dripping. The lower end of the nozzle body 2 has a protrusion to match the notch of the screw head 3 . Nozzle 4 protrudes from the lower port of screw head 3, and the cylindrical platform 9 at the upper end of nozzle 4 just matches the lower port of screw head 3. The circumference of cylindrical table 9 is designed with wire grooves to prevent nozzle 4 from connecting with screw head 3. slip occurs between the nozzles, the middl...

Abstract

The invention discloses a fan-shaped atomizing electrostatic spray head. A liquid medicine inlet is formed in the upper end of a spray head body, the lower end of the spray head body is connected with a spray tube through a swirling head, and a liquid flowing channel is formed in the middle of the spray head body; the spray tube is connected with the spray nozzle through threads; an electrode supporting base is fixed on the spray tube, and fan-shaped electrodes are connected on the bottom of the electrode supporting base; the two fan-shaped electrodes are distributed at front and rear sides of the spray nozzle; an open angle of 20 degrees is formed between the two fan-shaped electrodes which are integrally connected through a stainless steel electrode, each fan-shaped electrode is a fan-shaped hollow surface, and the fan-shaped open angle of the fan-shaped electrodes is 110 degrees. After being atomized, the liquid medicine is charged while passing through an induction electric field area in the front end of the spray nozzle and passes through the two fan-shaped electrodes which are provided with a 20-degree open angle and adaptive to atomizing flow, and droplets are conveyed to a target in an orientated manner along a power line track formed between the spray nozzle and the target, so that the penetrability, in the target, of the droplets can be improved through an airflow-assisted mode, possibility of contacting the droplets with the electrodes is reduced, and the charge effect of the droplets is guaranteed.

Description

technical field [0001] The invention relates to an electrostatic spray head with a fan-shaped induction electrode, in particular to a fan-shaped atomization device applied to the prevention and control of agricultural diseases and insect pests. The nozzle of this electrostatic spray head can spray the pesticide mist in a fan-shaped pattern, and is charged with a point charge when it leaves the nozzle, so as to improve the adhesion of the mist to the crop target. Background technique [0002] Pest control has always been an important management part of agricultural development. With the continuous improvement of pest control technology, higher and higher requirements are put forward for atomization devices used in pest control. The fan-shaped nozzle is a commonly used atomization mode in the control of agricultural diseases and insect pests. It is widely used in portable sprayers and boom sprayers. However, the conventional fan-shaped nozzle belongs to the hydraulic spray met...
