Description

The electronics insect catching or killing device

The utility model belongs to the agricultural machinery device, is the device that a kind of electronics lures the worm desinsection.

In recent years, northern vast cotton growing area is subjected to the serious threat of cotton bollworm disaster continuously, a large amount of underproduction of large-area cotton, and total crop failure is caused in the area that also has, and makes the peasant in cotton producing region suffer very big loss.Because cotton bollworm has surprising pesticide resistance, the peasant fears the cotton boll plague of insects as frightened floods, fire, so that dare not grow cotton again.Beginning in 1992, arousing the masses and reuse the old way that high-pressure mercury-vapor lamp lures worm in the area that has, just sets up high-pressure mercury-vapor lamp near the cotton field, digs a puddle under lamp, flies to moth worm under the lamp and can fall into water and be drowned.This method has obtained effect preferably.But some shortcomings are also arranged, and one also has quite a few moth worm not fall into water and dead, also has similar as winged insects such as mole cricket are difficult is drowned by water, thereby to causing very big harm near cotton field; So everybody is unwilling lamp bracket in the cotton field of oneself; Its two, use trouble, fetch water, backguy etc.This causes certain difficulty to popularization.

The utility model is that to lure worm, ultrasonic worm and the efficient high-pressure insecticidal technology of luring with the collection high frequency fluorescence that electronic technology realizes be the electronics insect catching or killing device of one.

A kind of electronics insect catching or killing device, the integral body that it is characterized in that this electronics insect catching or killing device is plastic construction, its plastic skeleton supports guardrail [5] lower shoe [6] electronic circuit box [7] by carrying handle [1] upper plate [2] and funnel [8] constitutes, fluorescent tube [3] is contained between upper and lower bottom plate [2], [6] and perpendicular to base plate, on the cylinder around the fluorescent tube outside, guardrail inboard the alternate metal high pressure aperture plate [4] of evenly distributed both positive and negative polarity is arranged, lower shoe [6] has the edge of ramped shaped and following funnel [8] to join.Drive fluorescent lamp, produce ultrasonic, reach high voltage source by the same electronic circuit generation that is contained on the same circuit board, as Fig. 2, shown in Figure 3, circuit board is contained in the plastic casing [7] of lower shoe bottom.Fig. 2 is to use the circuit of AC power, and the characteristics of this circuit are that circuit also produces ultrasonic signal and high-voltage dc voltage as the fluorescent lamp high frequency power supply time, and the two poles of the earth of its mesohigh aperture plate are connected on a, the b end of circuit respectively.The operation principle of circuit is: the 220V alternating current is through D ₁-D ₄Rectification, C ₁Obtain DC voltage V+ (about 300V) after the filtering, T ₁, T ₂Form oscillating circuit with pulse transformer B, frequency of oscillation is about 20-40KHz, and oscillating voltage passes through L ₀, C ₃The fluorescent tube of connecting with two constitutes the loop, makes it luminous.When connecting power supply, power supply V+ passes through R ₁Give C ₁Charging, voltage is charged to D ₆Breakdown voltage the time D ₆Conducting, C ₂Pass through T ₂Be joint and R ₅Discharge, T ₂Instantaneous conducting, because the positive feedback effect of pulse transformer B, circuit produces vibration, fluorescent tube is lighted immediately.The frequency of oscillation of circuit is 20-40KHz.High-tension coil N ₅With electricity, sense L ₀On same magnetic core, obtain high-voltage pulse, through diode D ₀Commutation capacitor C ₁₁Filtering obtains the dc high voltage of about 10KV at a, b end, is connected on the two poles of the earth of high pressure desinsection aperture plate, when the moth worm is run into the aperture plate that has high-tension electricity, gets an electric shock and dies immediately, and dead worm whereabouts is by the funnel plastic sack of packing into.Ultrasonic sounding component passes through C ₈Be connected between V+ and the o point, the ultrasonic electric current that 20-40KHz is arranged lures worm to use ultrasonic signal by S so S can send.Fig. 3 is to use the circuit of dc source, can be with the 12V storage battery as power supply, and the single-unit transistor T ₁' with transistor T ₂' constituting trigger generator, frequency is by R ₁', C ₁' decision, between 20-40KHz, triggering signal is passed through C ₃' trigger against leading type controllable silicon T ₃' constantly conducting and ending is at the elementary winding N of transformer ₁' middle formation alternating current, thereby at secondary windings N ₃' and N ₂' on obtain lighting the power supply and the required high voltage source of high pressure aperture plate of fluorescent lamp respectively.L wherein ₀' be the choked flow inductance, change inductance value and can change power output, the ultrasonic sounding component is by coupling capacitor C ₆' be connected on N ₁' two ends.Fluorescent tube among the figure can also can be used ultraviolet lamp tube with common fluorescent tube.

The utility model has the advantages that; With same ball bearing made using produce the high frequency power signal of lighting fluorescent lamp, desinsection is with the high voltage source signal and lure worm to use ultrasonic signal, can obtain effect preferably with lower cost, this light is pure cold light source, near bioluminescence, add action of ultrasonic waves, lure the worm better effects if; Owing to use high pressure aperture plate desinsection, use is simple and efficient is high; Total power consumption is few, and only 30-45W just can work a whole night with the storage battery of a 60AH.This electronics insect catching or killing device long service life can be used the several years.

Accompanying drawing 1 is the structural representation of electronics insect catching or killing device: the 1-carrying handle, and the 2-upper plate, the 3-fluorescent tube, 4-high pressure aperture plate, 5-supports guardrail, 6-lower shoe, 7-electronic circuit box, 8-funnel.Accompanying drawing 2 is to use the circuit of alternating current always to scheme, and accompanying drawing 3 is to use galvanic circuit always to scheme.

Concrete implementing method of the present utility model is: electronic circuit is contained on the bar printing wiring board, is installed in then in the plastic casing [7] of lower shoe bottom; It is the working of plastics of one that upper plate [2] lower shoe [6] supports guardrail [5] carrying handle [1], fluorescent tube is contained between the upper and lower bottom plate, high pressure aperture plate [4] is uniformly-spaced to strain on the cylinder that is arranged in fluorescent tube outside, support guardrail inside with fine wire, the two poles of the earth of aperture plate alternately, spacing distance is than a moth worm size point when young, and it is easy not causing interpolar discharge again.During use, the electronics insect catching or killing device is hung up certain altitude, connect power supply and just can use.
