A method for killing pests by direct current features that a pulse generator that is powered by DC power supply can provide electric pulses to two electric conductors to make them carry positive and negative charges, two atomized water beams formed by pressurized water are in contact with said two electric conductors and then merged to form charged water beam, and the charged water beam is sprayed to agricultural crops to kill pests. Its equipment is composed of two nozzles, two water pipes, operating unit, pressurized water source, pulse generator, two electric conductors, two insulating wires and DC power supply. Its advantages are high effect and no environmental pollution.
Description
The present invention relates to a kind of method of deinsectization, specifically is a kind of deinsectization method that uses direct current as the deinsectization material, also relates to the device that satisfies this method of realization simultaneously.
Remove the various insects harm the crops for going out, existing technology is to use the material of corresponding agricultural chemicals as deinsectization, with the diluted pesticide spray solution on damaged by vermin crops or fruit tree, effectively deinsectization.But use the material of agricultural chemicals as deinsectization, because of its existing toxicity causes the serious consequence of the environmental pollution and the destruction ecological balance more and more obvious, when especially being sprayed on the fruits of vegetables and crops with the pesticidal solutions of toxicity, vegetables and crops fruit will be polluted by etch to some extent, after people are edible, residue in the physical and mental health that the drug toxicity in it seriously endangers people, also endanger livestock simultaneously.Although scientists has worked out higher effective and lower toxic pesticide by continuous effort, reduced its influence to a certain extent, and the existence still of its toxicity, still make us worry.
The purpose of this invention is to provide a kind of method of using killing pests by direct current, and device that satisfy to realize this method, the present invention does not produce pollution to environment and crops and fruit thereof when effective killing pests.
For achieving the above object, the inventive method is achieved in that uses the material of direct current as killing pests, make positive and negative electrode with two electric conductors, direct current is produced through the effect of pulse generator is enough to the pulse power of killing pests, and delivers to corresponding positive and negative electrode electric conductor; Spray two strands of spray water bundles with press water through two shower nozzles, and make these two strands of spray water bundles respectively via and contact described positive and negative electrode electric conductor, thereby make two strands of spray water bundle cross sections distinguish discontinuous band positive and negative charges, and become positive and negative sub-electrode, two stocks do not contact and mixing automatically with the spray water Shu Suihou of positive and negative charge, form charged water bundle and water droplet, thereafter directly be sprayed on them on damaged by vermin crops, fruit tree is first-class, insect touches charged water bundle or water droplet, then by electric shock and death, thereby realize killing pests effectively.
The device of realizing said method is: referring to Fig. 1, two shower nozzles 1 and two water-supply-pipes 2 are set, and crosshead 3, the leading portion of crosshead is two fork arms, two shower nozzles are connected to two fork arm front ends of crosshead, two shower nozzles are connected with an end of two water-supply-pipes respectively, be provided for controlling the valve 4 at shower nozzle water source on the hydraulic pipeline, the other end of two water-supply-pipes when user mode and pressure water source 5 join, distance between two shower nozzles and reach automatic contact and mixing towards satisfying the spray water bundle sprayed by this two shower nozzle, distance between two shower nozzles and towards relevant with employed source pressure, such as: when when certain, under the big situation of source pressure, the distance between two shower nozzles can be correspondingly big, otherwise, then should be smaller.When Open valve 4, when press water was delivered to two shower nozzles through water-supply-pipe, two shower nozzles then ejected the spray water bundle respectively.The above then is a pressurized water ejector.In addition, the DC-pulse source apparatus also is set, be provided with impulse generator 6 and two electric conductors 7, two electric conductors are located at respectively on the spout of two shower nozzles 1, wherein an electric conductor joins by the positive pole of insulated conductor 8 with the impulse generator output, and another electric conductor joins by the negative pole of insulated conductor 9 with the impulse generator output, under the user mode, impulse generator input termination dc source 10 is established pulse power switch 11 on the insulated conductor.When opening switch 11 connection power supplys, impulse generator provides the pulse power to two electric conductors, and two electric conductors then become the electrode of band positive and negative charge respectively.At the same time when Open valve 4 and pulse power switch 11, two strands of spray water bundles that eject by two shower nozzles then respectively via and the electric conductor of contact zones positive and negative charge, two strands of spray water bundles then are with positive and negative charge respectively, because the effect of hydraulic pressure, two gangs of spray water Shu Suihou with positive and negative charge contact and mixing automatically respectively, and the water bundle and the water droplet of formation tape pulse electricity, by the control operation frame directly be sprayed on them on damaged by vermin crops or fruit tree first-class, insect touches charged water bundle or water droplet then by electric shock and death, thereby realizes described inventive method.
Because the inventive method is used the material of direct current as killing pests; with spray water bundle and water droplet carrier as Pulse Electric; by directly be sprayed on the damaged by vermin crops or fruit tree first-class; insect gone out remove; and provide the device of realizing this inventive method; therefore; the present invention is when effective killing pests; environment and crops and fruit thereof are not produced pollution; to the protection environment and the ecological balance; physical and mental health to the protection people has important role, and its technique effect and social effect are remarkable.
