1 is a partial cutaway perspective view showing a portion of the pest collecting device according to a preferred embodiment of the present invention, Figure 2 is a cross-sectional view of FIG.

Referring to the drawings, the pest collecting device 100 includes a suction pipe 110, a suction fan 130, opening and closing fan 140, a collecting network 150 and a light source 160.

The suction pipe 110 is supported and coupled to the four legs 121 applied to the frame.

The suction pipe 110 is formed in a cylindrical structure. Preferably, when the foreign matter such as debris of the pest is attached to the rotary blade 131 of the suction fan 130, the inner diameter of the portion corresponding to the suction port 111 so that the interference with the suction pipe 110 can be suppressed It is preferable to have the expansion portion 112 extended outward larger than the inner diameter of (113).

In addition, when the suction pipe 110 having the expansion portion 112 or not shown, but the straight pipe-type suction pipe is applied, the rotary blade 131 of the suction fan 130 is spaced above a predetermined height above the end of the suction pipe. desirable.

The middle portion 113 of the suction pipe 110 is provided with a shielding ring 115 formed to be inclined downward from the inner surface of the suction pipe 110 by a predetermined angle so as to reduce the internal flow path of the suction pipe 110.

The shielding ring 115 is applied to apply the shedding fan 140 having a smaller outer diameter than the suction fan 130.

Opening and closing fan 140 is rotatably installed on the horizontal bar 145 installed in the horizontal direction in the lower portion of the suction pipe 110 to open and close the hole (115a) of the shielding ring plate (115). Reference numeral 146 is a bearing.

When the external air flows in by the suction fan 130, the opening / closing fan 140 changes the angle of the rotation blade 141 with respect to the rotation shaft 142, so that a gap is formed between the rotation blades 141. Correspondingly rotated. In addition, in the state where no external air flows in, the rotary blades 141 return to the initial position perpendicular to the rotary shaft 142, and the rotary blades 141 mutually come into contact with each other and return to a circular disk shape. The opening and closing fan 140 that is operated in this way is commercially available, and as an example, the structure of the fan disclosed in Korean Utility Model Registration No. 291020 or the fan structure of the ventilator disclosed in Korean Utility Model Publication No. 1999-9949716 is known. Description is omitted.

The separation distance between the opening and closing fan 140 and the shielding ring plate 115 is the separation distance between the shielding ring plate 115 and the rotary wing 115 of the shedding fan 140 when the opening and closing fan 140 is inactive. What is necessary is just to apply suitably to the extent that deviation | deviation is suppressed. As an example, when the moth is to be captured, a separation distance between the shielding ring 115 and the rotary wing 115 of the open fan 140 may be applied to several millimeters or more.

Parabolic net 150 is installed to extend to the bottom hanging on the hook 117 formed on the outer peripheral surface of the suction pipe (110).

The lower part of the parabolic net is closed by a binding member such as a string 152.

The suction fan 130 is installed to face the opening 114 of the suction pipe 110 in the support frame 125 installed at a predetermined height spaced apart from the expansion part 112 of the suction pipe 110. Reference numeral 135 is a motor for driving the suction fan 130.

The light source 160 is installed on the upper surface of the support frame 125.

The light source 160 is preferably a near-ultraviolet fluorescent lamp that emits near-ultraviolet light. As a near-ultraviolet fluorescent lamp, it is preferable to apply the light which radiate | emits the wavelength of 350-360 nanometers.

Such near-ultraviolet fluorescent lamps offer the advantage of reducing fatigue to surrounding fruit trees when lit at night. That is, in the case of applying a light source that emits visible light, visible light emitted at night may disturb the dormancy of the fruit and increase the fatigue of the fruit. In view of this, it is preferable that a near-ultraviolet fluorescent lamp is applied as the light source. Do. Such near-ultraviolet light sources are commercially available and description of the detailed structure is omitted.

Power supply lines to the motor 135 and the light source 160 have been omitted to avoid complexity of the drawings.

The operation of the pest trapping device of this structure will be described.

First, when the light source 160 is turned on at night and the suction fan 130 is operated to collect pests, the pests gathered toward the light source 160 are sucked by the air flow formed by the suction fan 130. ) Flows inside. In this process, the pest hit the rotary blades 131 of the suction fan 130 is mostly killed by the impact or grinding.

On the other hand, the opening and closing fan 140 is rotated by the airflow generated into the suction pipe 110 by the suction fan 130. Therefore, the pests introduced into the suction pipe 110 by the opening and closing fan 140 rotated to have a gap at a predetermined angle between the rotary blades 141 pass through the gap between the rotary blades 141 and the collecting network 150. ) Is captured. In this process, some of the pests hit the rotary wing 141 of the opening and closing fan 140.

Therefore, the pest may be impacted in multiple stages by the suction fan 130 which is directly rotated by the motor 135 when the motor 135 is driven and the opening and closing fan 140 which is rotated by the airflow generated by the suction fan 130. This provides the advantage of lowering the survival rate of pests.

In addition, since the opening and closing fan 140 operated by the airflow generated by the suction fan 130 is operated by external airflow, not by electric power driving, there is less fear of damaging the device.

On the other hand, although not shown, the power to the motor 135 and the light source 160 is selectively selected at a time set to automatically operate the power supply of the suction fan 130 to the motor 135 and the light source 160 only at night. Of course, you can install a timer or optical sensor module to supply.

The optical sensor module turns off the power supply path when the external illumination exceeds the set level, and selectively turns on the power supply line by comparing the output signal of the light receiving element with the set level so that the power supply path is turned on only when the light level is lower than the set level. The only thing that can be turned on and off is applied.

As described above, according to the pest trapping apparatus according to the present invention, it provides an advantage of reducing the operation error and damage of the device due to the debris of the pest generated during the trapping process while increasing the capture rate of the pest.
