The prior traps of this kind have the following problems: because the pest flies out escape again after flying into the trapper because of avoiding, consequently must set up the baffle of certain quantity, the existence of baffle can influence the scope of trapper undoubtedly, if the pest flies into have between two guide boards of baffle, just can't carry out effectual trapper to the pest.

Disclosure of Invention

The invention aims to provide a flying pest trapper, which aims to solve the technical problem that the range of a trapping area is influenced because a baffle for preventing pests from flying out and escaping needs to be arranged in the prior art.

In order to solve the technical problems, the technical scheme of the flying pest trapper provided by the invention is as follows:

the utility model provides a flight pest trapper, including traping a section of thick bamboo, the peripheral distribution of traping a section of thick bamboo has a plurality ofly to be the guide board of radial distribution as the center with traping a section of thick bamboo axis, all form by outer to interior narrow guide channel gradually of hole between each two adjacent guide boards, traping on the section of thick bamboo and all offering along the section of thick bamboo pest clearing hole that traps that the upper and lower direction extends between each adjacent guide board, the upper end and the lower extreme of traping a section of thick bamboo are provided with bobbin top and bobbin bottom respectively, bobbin bottom pest clearing hole has been seted up to central point on the bobbin bottom, the downside of bobbin bottom is provided with album worm bag, the downside of bobbin bottom still is provided with album worm fan, the bobbin top is big-end-up's toper structure, the axis of bobbin top is located bobbin bottom pest clearing hole, the flight pest is blockked by the bobbin top and can not fly out in.

The pest through holes on the top and bottom of the cylinder are arranged coaxially.

Each guide plate is an equiangular spiral line-shaped arc plate with the consistent protruding orientation direction, and the guide channel is an equiangular spiral line-shaped guide channel.

Trapping lamp beads are arranged on the periphery of the top of the cylinder.

But each guide board with traping a articulated linking to each other of section of thick bamboo can the horizontal hunting, is provided with between traping a section of thick bamboo and the guide board and is used for exerting the effort so that the guide board is in the elastic construction of swing range intermediate position in windless environment to the guide board, and the guide board can overcome the effort of elastic construction and swing in windy environment.

The elastic structure is a torsion spring fixed on the guide plate, and two blocking arms of the torsion spring are blocked on the trapping cylinder.

The invention has the beneficial effects that: according to the invention, under the action of the insect collecting fan, the insect collecting bag generates a negative pressure environment, the flow direction of the air flow is from the guide channel to the inner cavity of the trapping cylinder and finally to the insect collecting bag, after flying insects enter the inner cavity of the trapping cylinder through the guide channel, the flying insects cannot fly from one side of the trapping cylinder to the other side to escape due to the existence of the cylinder top of the conical structure, and under the action of the air flow, the flying insects can fly downwards along the cylinder top of the inverted conical structure and then enter the insect collecting bag through the cylinder bottom insect through the hole. The bobbin top of back taper structure had both played the effect that the guide was flown the pest towards bobbin base pest through hole orientation flight, played the effect that hinders the flight pest and fly out the escape by the other one side of traping a section of thick bamboo again, because the central point from traping a section of thick bamboo puts and stops the flight pest to escape, consequently can all set up traping a section of thick bamboo pest through hole on the traping a section of thick bamboo between each adjacent guide board, increases trapper regional scope, improves and traps the effect.

Furthermore, the guide plate is an arc-shaped plate, so the guide channel is also an equiangular spiral guide channel which gradually narrows from outside to inside, the arc line in the arc-shaped plate is an equiangular spiral line, and the guide channel in the shape is more in line with the phototactic flight behavior of moth pests (in the design, the periphery of the conical top at the center of the trapping cylinder is used as a harmful insect attracting light source, and the directional flight track of the moth pests to the light source is an equiangular spiral, as shown in fig. 9), so that the flying pests are more easily guided to fly towards the pests through holes of the corresponding trapping cylinder; the curved guide channel makes flying pests fly easily and not fly out easily. In addition, the arc-shaped guide plate has the function of preventing flying pests from escaping secondarily, after the flying pests are attracted into the guide channel, most flying pests can enter the pest trapping barrel through holes under the action of negative pressure, but a small part of flying pests can fly along the outer convex side of the guide plate and escape from the guide channel, when the flying pests fly to the outer edge position of the guide plate along the outer convex side of the guide plate, the guide plate has the function of guiding the flying pests to enter the adjacent guide channel, namely the flying pests fly along the outer convex side of the guide plate, and when the guide plate disappears suddenly, the flying pests can fly into the adjacent guide channel, so that secondary trapping of the flying pests is realized, and the trapping effect of the flying pests is ensured by the guide channels arranged in sequence along the circumferential direction.

Furthermore, the guide plate is hinged with the trapping cylinder, and is positioned in the middle of the swinging amplitude under the action of the elastic structure in an outdoor windless environment, and the inlets of all the guide channels are consistent in size, so that flying pests are uniformly trapped; and when outdoor when having wind, the guide board of windward side receives the wind force effect, can overcome elastic construction's effort, and two adjacent guide boards that correspond can open to increase windward side guide channel's area, more flight pest are also followed the wind flight this moment, and the guide channel area of windward side increases, thereby can catch more flight pest. And in this process, the guide board is the arc structure, has then increased the surface area of guide board for the wind-force grow that the guide board of windward side received, open more easily during windy environment.
