The utility model relates to crops device for administration of drugs and spray head technical field, specifically a kind of double flow channel auxiliaryStatic nozzle.
Background technique
For a long time, orchard application mostly uses greatly the large capacity spraying method of per hectare 600L or more, and process was national in recent yearsTo a large amount of investments of agricultural machinery, popularity, air-assisted spraying can for the low capacity air-assisted spraying of current 50~200L of per hectareIt to improve the penetration capacity of droplet, but also results in a large amount of pesticides and is lost to soil, the utilization rate of pesticide, agriculture can not be effectively improvedMedicine drift amount is big, is contaminated environment also.
Therefore, to overcome the shortcomings of above-mentioned technology and to design a structure simple, pesticide utilization rate can be effectively improved, is subtractedFew pesticide drift, a kind of double flow channel auxiliary electrostatic spray heads to reduce environmental pollution, exactly inventor's problem to be solved.
Utility model content
In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of double flow channel auxiliary electrostatic spray heads,Structure is simple, can solve charged droplets the problem of absorption and carrying capacity are decayed in space on electrode attachment.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of double flow channel auxiliary electrostatic spray heads,It includes shell, stream cover, profiling electrode, electrode tip holder, hollow cone nozzle, nozzle carrier, connecting pipe, outside the end of the shellSide is fixedly connected with stream cover, and inside the housing, described connecting pipe one end connects nozzle carrier, the company for the connecting pipe settingThe adapter tube road other end connects medical fluid delivery pipe, and hollow cone nozzle, the sky are fixed between the nozzle carrier and connecting pipeThe front end of heart cone nozzle is provided with filter screen, and in stream cover, the electrode tip holder is internally provided with profiling for the electrode tip holder settingElectrode, the electrode seating face are covered with insulating layer, the electrode tip holder, connecting pipe central axis be located at same level, instituteIt states electrode tip holder, nozzle carrier and air-flow is divided into dual channel, outer airflow path, the nozzle are provided between the electrode tip holder and shellInterior air-flow runner is provided between seat and electrode tip holder.
Further, the stream cover, electrode tip holder are that high insulating epoxy is made.
Further, the profiling electrode is induction type electrode.
Further, the profiling electrode is tapered electrode, angle of taper and the hollow cone nozzle of the profiling electrodeSpray angle is consistent.
The beneficial effects of the utility model are:
1, the utility model static nozzle is using double flow channel auxiliary systems, it is charged after droplet in interior airflow path air-flowBy fast transport to crop target under effect, for charged droplets in target zones around absorption, the air-flow of outer airflow path can prevent lotusElectric droplet adsorbs deposition at spray head, to improve pesticide in the deposition at the target back side, reduces pesticide drift, improves pesticideUtilization rate reduces environmental pollution.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments, it should be appreciated that these embodiments are merely to illustrate thisUtility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instructionLater, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms also fall within applicationThe appended claims limited range.
It is the utility model structure diagram referring to Fig. 1, a kind of double flow channel auxiliary electrostatic spray heads of the structure include outerShell flows and covers 1, profiling electrode 2, electrode tip holder 4, hollow cone nozzle 6, nozzle carrier 7, connecting pipe 8, outside the end of the shell 10Side is fixedly connected with stream cover 1, and the connecting pipe 8 is arranged inside shell 10, and described 8 one end of connecting pipe connects nozzle carrier 7,8 other end of connecting pipe connects medical fluid delivery pipe 9, and hollow cone spray is fixed between the nozzle carrier 7 and connecting pipe 8Mouth 6, the front end of the hollow cone nozzle 6 are provided with filter screen 5, and the setting of electrode tip holder 4 is in stream cover 3, the electrode tip holder 4It is internally provided with profiling electrode 2,4 surface of electrode tip holder is covered with insulating layer 1, the center of the electrode tip holder 4, connecting pipe 8Axle position is in same level, and air-flow is divided into dual channel by the electrode tip holder 4, nozzle carrier 7, between the electrode tip holder 4 and shell 10It is provided with outer airflow path, is provided with interior air-flow runner between the nozzle carrier 7 and electrode tip holder 4.
Stream cover, electrode tip holder are that high insulating epoxy is made.Profiling electrode uses induction type electrode, is placed in electrode tip holderIt is interior.High voltage power supply, input voltage 12V are selected, output voltage is 0~8000V.Medical fluid is under the action of liquid pump operating pressureIt into nozzle and is atomized, under high voltage power supply effect, forms high voltage electric field between profiling electrode and spray, droplet after atomizationAfter into electric field region can by charge opposite with electrode on induction band, it is charged after droplet under interior airflow path airflow function quiltFast transport is to crop target, and for charged droplets in target zones around absorption, the air-flow of outer airflow path can prevent charged droplets from existingDeposition is adsorbed at spray head, to improve pesticide in the deposition at the target back side, is reduced pesticide drift, is improved pesticide utilization rate.
To keep droplet charging effect best, it must guarantee that electrode and spray are in optimal relative position, therefore profiling is electricPole is designed to the tapered electrode consistent with the spray angle of hollow cone nozzle.
The utility model makes droplet be adsorbed on plant surface, greatly by the electrostatic effect between charged droplets and crop targetThe deposition of medical fluid is increased greatly, is reduced pesticide drift, is effectively raised pesticide utilization rate, reduce environmental pollution.
