Description

Electric insect killer

The utility model relates to a kind of bug killing equipment that uses direct current as the deinsectization material.

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 utility model provides a kind of device that uses killing pests by direct current, and the utility model does not produce pollution to environment and crops and fruit thereof when effective killing pests.

For achieving the above object, this device is achieved in that 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, the distance between two shower nozzles and towards relevant with employed source pressure, such as: when when certain, under the big situation of source pressure, 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.

Because this device uses 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, therefore, when effective killing pests; environment and crops and fruit thereof are not produced pollution; to the protection environment and the ecological balance, the physical and mental health of protecting people there is important role, its technique effect and social effect are remarkable.
