People are sprayed onto on the crops after using sprayer that agricultural chemicals is atomized into droplet, to reach the purpose of killing pest on crop.As vacuum electric injector and power driven mist blower, thereby the situation that makes people break away from artificial hand pressure sprayer has alleviated labour intensity greatly, can realize the spraying of ultra-low volume simultaneously, has improved atomizing effect and has reduced dosage; Electrostatic atomiser and DW-77-A type electronic sprayer not only make medical liquid atomizing good, and the liquid medicine is electronegative evenly, has strengthened the deposition effect of soup droplet in crop surface.Above-mentioned several sprayer is reducing the soup consumption, improve atomizing effect and insecticide efficiency aspect very obvious improvement is all arranged, but be still by the desinsection of spraying insecticide, and use chemical pesticide that insect is developed immunity to drugs to medicine for a long time and reduce drug effect, thereby increased production cost, and because a large amount of uses of chemical pesticide and serious environment pollution.

The utility model is intended to solve the water droplet desinsection with charged, not only can reduce the problem of environmental pollution of chemical pesticide, and has solved the resistance to the action of a drug of insect to agricultural chemicals, to improve insecticide efficiency.

The technical scheme that realizes the foregoing invention task is: agricultural electric energy desinsection spraying machine is by the water pressure accumulater, several parts of charged water droplet sprayer unit and supply unit are formed, the water pressure accumulater is by cistern (7), the water booster body, filter (3), check valve (6) constitutes with accumulator (8), in having comprised, charged water droplet sprayer unit establishes electrode, can spray the fountain head (14) of charged water droplet, regulate the fountain head adjusting bracket of fountain head position and the splitter of control fountain head spread of spray by control stick, supply unit has comprised makes two fountain head ejections respectively with the composite power source (18) and battery (17) of positive negative electricity water droplet, and two fountain heads are linked to each other with two cover water pressure accumulaters by water pipe respectively.Composite power source (18) is made of inverter (22), high frequency bridge rectifier (23) and composite network (24), by high-voltage conducting wires respectively with two fountain heads in an electrode join.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

The agricultural electric energy desinsection of Fig. 1 spraying machine structure chart;

The portable agricultural electric energy desinsection spraying machine structural representation of Fig. 2;

Fig. 3 composite power source circuit diagram.

The water booster body that consists of by rocking arm (1), connecting rod (2) and liquid pump (5) or by generator (26), water pump (27) with the water in the cistern (7) through filter (3) suction accumulator (8), after the hydraulic pressure in the accumulator reaches 0.1-2.5MPa, water flows into fountain head (14) by water pipe (12), High-Pressure Water through behind the electrode from the fountain head diameter be several millimeters aperture high speed ejection, be atomized into the charged water droplet that particle diameter is small, be evenly distributed. Regulate fountain head adjusting bracket (13) by control stick (11), and cooperate the distributed areas scope of controlling the water smoke that ejects with splitter (16).

Battery E(17) 12 volts of voltages are supplied with integrated voltage-stabilized parts Ic₁，Ic ₁9 volts of voltages of stable output are given integrated component Ic₂，Ic ₂The square wave of output certain frequency is given power amplification part B G₁And BG₂, the signal of telecommunication after the amplification passes through L₁And L₂Be coupled on the power supply composite network (24).

Battery (17) and Ic ₁9 volts of voltages after the voltage stabilizing are defeated by integrated component Ic simultaneously₃，Ic ₃The alternating current that output frequency is adjustable, B boosts through high frequency transformer, has realized that direct current is transformed into the function of the inverter of high-frequency alternating current (22). Inversion is pressed and is exported to high-frequency rectification parts D₅－D ₈(23), high-frequency alternating current has become direct current, is defeated by power supply composite network (24) again, has also given (24) by the output of (22), and composite network (24) carries out alterating and direct current stack, at composite network Output namely has alternating current, direct current is arranged again, high-voltage conducting wires (19) is supplied with the output in (24) metal electrode (20) of fountain head (14), respectively there is a cube electrode to contact with water pipe mesohigh current in two fountain heads, when two bursts of water mist spray on crops, thereby load R1 has just connected electricity, just has electric current to flow through on the polypide. Composite power source can provide the high voltage of non-sinusoidal waveform, and the electric field that this high pressure forms can not only make two bundle water of fountain head ejection charged, and can accelerate the microballon of water, in the electrode reaction that produces electrolysis; By the district, inorganic ions is made directional migration in the water at DC current; Alternating current is also by the water smoke district, and AC and DC is applied on the insect in the water smoke district simultaneously, has strengthened the stimulation of electric current to polypide. Water microballon with electric charge has the characteristic of Automatic-searching crops, again because the water bead diameter is little, electrically charged, and crops are to take root in the earth, but water microballon diffraction is to stem of plant, leaf back, evenly distribute in crop surface, so electric energy desinsection spraying facility penetrability, the good characteristics of topped property.

Charged water droplet touches on the polypide of crop, just has electric current to flow through polypide, makes polypide produce the reaction of getting an electric shock; When the current strength I of passing through polypide is very faint, twitch after polypide gets an electric shock and come back, when I increases, the insect big quantity of fluid that spues is shrivelled state (though dead, harmless to crop immediately), when current strength I＞10mA, the insect of shocking by electricity is death, particularly larva at once, easier death.

By regulating the condition of power supply of composite power source, make current strength I＜several milliamperes, irrigate, applying fertilizer can stimulate plant growth simultaneously, can kill pest on crop when I＞10mA.
