Description

Crop disease and insect pest treating machine

The present invention relates to the method and apparatus of crop pest control, be meant especially and use high voltage electric field, kill the method and apparatus of crop pests, germ.

The damage by disease and insect of crops is is normally prevented and treated with the atomizers spray agricultural chemicals.Like this, the toxicity of agricultural chemicals remains in the ripe crops easily, the harm health of human body.And, spray insecticide pollution of ecological environment.

Purpose of the present invention is exactly: provide a kind of to the harm of crops non-residual toxicity, pest control method that does not pollute the environment again and equipment.And this equipment also will have the function that promotes plant growth speed.

For finishing above-mentioned purpose, the method that the present invention takes is: producing high voltage electric field with electronic circuit is that crop insecticide is cured the disease.The high-tension electricity field energy is directly shot insect dead; The ion that the high voltage electric field ionized air produces can remove germ extremely.Electronic circuit is made power supply with accumulator jar or electric main behind step-down rectifier, supply with the alternating current that the transistor oscillating circuit produces 1K～20KHz, and this alternating current amplifies through power amplification circuit, transformer boosts, the high-tension electricity of output 15KV～50KV is added on the active electrode, produces high voltage electric field.

The present invention kills crop pests with high voltage electric field, kills the crop germ with the ion that the high voltage electric field ionized air produces, and does not therefore have the harm of residue of pesticide in ripe crop and fruit, produces real green food.When the present invention uses in the vegetable melon and fruit booth, electric field electrode can frame at ceiling, the nitrogen that produces during ionization becomes plant food; Accept the high voltage electric field effect when making crop long, can strengthen the crop metabolic function, promote plant growth speed, the premature ripening listing.

Specific embodiment of the present invention is as follows:

Accompanying drawing 1 is the circuit theory diagrams of the specific embodiment of the invention.Accompanying drawing 2 is the present invention's electrode J scheme of installations when using in the crop-planting booth.Accompanying drawing 3 is that present device moves electrode J vertical section schematic diagram used when using.Accompanying drawing 4 is block diagrams of present device.

In circuit theory diagrams shown in the accompanying drawing 1, the 220V civil power is depressurized to about 20V with transformer B1, after bridge rectifier D1 rectification, as the oscillation step-up circuit power supply, perhaps gives accumulator jar E charging by K switch.Capacitor C 3 is power filtering capacitors, is connected between the K switch positive source and ground afterwards.Inductance L one termination power positive pole, the other end is connected with capacitor C 1, capacitor C 2, and tap terminals is connected with resistance R 2; The other end of capacitor C 1, resistance R 2 is all received the emitter stage of transistor T 1; The base stage of another termination transistor T 1 of capacitor C 2; Resistance R 1 connects between transistor T 1 base stage and the ground; Resistance R 3 connects between transistor T 1 colelctor electrode and the ground; They form intermittent oscillation circuit, the about 16KHz of frequency of oscillation.The base stage of transistor T 2 directly is connected with the colelctor electrode of transistor T 1, and the alternating current that vibration is produced carries out voltage amplification.Transformer B2 primary coil connects between the colelctor electrode and positive source of transistor T 2, and secondary coil connects between the base stage and emitter stage of transistor T 3, and it is passed to transistor T 3 with alternating current and carries out power amplification.Transformer B3 primary coil connects between the colelctor electrode and positive source of transistor T 3, and it is elevated to alternating voltage about 20KV, from secondary output, secondary coil one end ground connection, a terminating diode D2 positive pole is again after rectification, be added on the electrode J, produce high voltage electric field.

Transformer B1 primary coil with 0.25 enamel-covered wire around 1300 circles, secondary coil with 0.8 enamel-covered wire around 120 circles.Iron core GoEB22 * 28.Elementary usefulness 0.31 enamel-covered wire of transformer B2 is around 100 circles, and secondary usefulness 0.31 enamel-covered wire is around 45 circles, iron core E4 * 6.Transformer B3 will resemble and manufacture the television set line output transformer, elementary usefulness 0.6 high strength enamelled wire is around 30～50 circles, and secondary usefulness 0.15 high strength enamelled wire is around 2000～3000 circles, and divides tens sections to separate coilings, line Bao Yaoyong insulating resin is sealed, iron core U type magnetic core.The line of transformer B3 secondary end and diode D2, and the line of diode D2 and electrode J all will be used high-voltage insulating wire.The link of rectifying tube D2 and appearance thereof also will be sealed with insulating materials.Inductance L with 0.12 enamel-covered wire on the skeleton that M6 * 12 magnetic cores are arranged, around the 350+350 circle, middle tap.

Other element model parameter of embodiment of the invention circuit is as follows: D1, four IN5403; D2,2DGL1E; C1,0.068; C2,0.01; C3,50V2200uF; R1,100K; R2,24 Ω; R3,1K; T1, IN5401; T2,3DA87C; T3,3DD15D.Accumulator jar E is with the polyphone of two 12V.

The circuit part of present device is installed in the insulation shell.Except that transformer B1, accumulator jar E, other element is installed on the circuit board, and soaks insulated paint and do moistureproof the processing, and K switch is installed in is convenient to the place of operating on the shell.
