JP5597125B2 - Net structure for preventing flying and capturing flies - Google Patents

Description

  The present invention is a net structure in which cattle, pigs, chickens and other livestock are trapped and exterminated in the barn so that insects such as flies fly outside the barn and do not spread, and The present invention relates to a window frame provided with this net structure.

  Conventionally, there are many complaints regarding sanitary pests such as flies generated in a barn in a residential area near a barn such as cattle, pigs and chickens. Sanitary pests can also be a medium for parasites and infectious disease viruses, so it is desirable to capture them, eliminate them, and prevent them from spreading in the vicinity.

  Measures against these hygienic pests include spraying a fast-acting insecticide directly on the insect body, or spraying a residual insecticide on the walls or shelves of livestock houses, A typical method is to install a mixture of honey, etc., which is favored by sanitary pests.

  On the other hand, as a technique for exterminating sanitary pests with insect repellent nets, a net for preventing fly flying (Patent Document 1) in which fibers are impregnated with pesticides, and a net-like pest control material in which pesticides are kneaded into a material resin (patents) Document 2) has also been proposed.

  Among these, according to the techniques disclosed in Patent Documents 1 and 2 using an insect repellent net, when the net is installed in an open part of a barn, the entry of sanitary pests is prevented and the net is contacted Can also be expected to kill insects.

  However, the fly flying prevention net of Patent Document 1 is such that the material fiber is immersed in an insecticide solution and then dried to leave the insecticide on the fiber surface. There has been a problem that a large scale is required and a considerable time is required from immersion to drying.

  On the other hand, the net-like pest control material of Patent Document 2 is a natural release of an insecticide (permethrin preparation) kneaded into the material fiber, and shows a high repellent and insecticidal effect for a long time, but this insecticide is an irritation to the human body It is highly toxic to humans and aquatic organisms, and since it is stipulated by international guidelines that it should be stored away from feed, there are concerns about adverse effects on feed and livestock when used in barns It is.

  The present invention has been invented in view of such circumstances, and is a simpler and more economical net structure capable of capturing and removing flies and the like, and preventing flight diffusion to the vicinity. The purpose is to provide.

  In order to solve the above-mentioned problems, the present invention is a net structure for preventing and capturing flies and the like, and the outer net and the inner net are stretched in parallel with each other at an appropriate interval and at least both side surfaces thereof are shielded. A narrow shielding space was formed, and a means was adopted in which a large number of fly entry holes were provided in the inner net, and a bowl-shaped fly pool was provided in the longitudinal direction of the lower end portions of both nets.

  Furthermore, the means of shielding the upper side surface of the shielding space was adopted.

  In this way, the net has a shielded double structure, and by providing a fly intrusion hole in the inner net, a trap structure is formed in the shielded space, so that the fly is reliably captured, and the falling fly is stored in the fly It can be killed spontaneously, or it can be exterminated by injecting water, oil, insecticides such as insecticides, etc. into this fly pool. This prevents the fly from spreading to the vicinity.

  And the means of providing a spacer in the vertical direction between the outer net and the inner net was adopted.

  This spacer prevents the net from being slack so as to prevent the net from sagging and secures a space portion.

  Further, the mutual distance between the outer net and the inner net and the size of the intrusion hole provided in the inner net are selected and set according to the type of fly or the like.

  Moreover, the means which provided the said intrusion hole in a zigzag form in an inner side net | network, or the means provided in the lower side compared with the upper side of an inner side net | network was employ | adopted.

  There are many types of flies, such as house flies, giant flies, and flies, so that the distance between the nets forming the trap structure and the size of the intrusion hole can be changed appropriately according to the type and size. In addition, the position of the intrusion hole is set so that the fly can be easily captured. In addition to providing the intrusion holes uniformly, depending on the ecology of flies, more intrusion holes may be provided on the lower side or larger intrusion holes may be provided.

  Moreover, the means of applying an attractant to the outer net and / or the inner net was adopted.

  The attractant can also attract more flies directly to the trap structure, making it more sure to prevent and eliminate flies.

  And the means of applying the net structure of the said structure to window frames, such as a barn, was employ | adopted.

  In particular, in a barn or the like where there are many complaints, the above-mentioned net structure is adopted for the window frame, thereby preventing flies from being scattered from the window of the barn or the like to the vicinity. Here, the window frame may be openable and closable like a screen door, or may be a fitting type.

  According to the net structure of the present invention having the above-described configuration, the fly can be positively captured and exterminated without causing the fly to escape to the outside of a barn or the like, thereby reliably reducing the number of flies flying. Therefore, there is a special advantage that it is possible to deal directly with complaints received from neighboring residents.

  In addition, because it is a physical insecticide that does not use an insecticide as in the past, running costs are unnecessary, which is advantageous for cost reduction, is highly safe for humans and livestock, and is subject to restrictions on installation location. An excellent effect can be expected.

  Furthermore, since the net is used, the ventilation required for a barn etc. is high, and the sun shielding effect can be obtained.

  And, the structure of laying the net doubled can be freely selected from various installation styles such as hanging style, window frame style, open style, etc., and can be easily installed by anyone. There is utility.

  In addition, when an attractant is applied to the net, an additional effect of more efficiently capturing flies and the like can be expected.

It is explanatory drawing which cuts off the outline of the net structure which concerns on this invention, and is shown partially. It is a longitudinal cross-sectional view of a net structure. It is explanatory drawing which shows an example of a use condition.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. First, the ecology (behavior and property) of flies as a premise thereof will be described. The inventor has been researching and observing the ecology of flies for many years, and as a result, obtained various interesting findings. Of these, matters directly related to the present invention will be described below.

[Fly Ecology]
(1) Flies cannot go straight when moving by flying. Moreover, it does not move downward. That is, flies tend to fly in a zigzag upward direction.
(2) House flies and fruit flies rarely move from the source to about 5 m in the horizontal direction and 2 m or more in height.
(3) The house fly and the house fly move crawls, but the house fly moves mainly while flying.
(4) The house fly must move about 200 times its wing weight.
(5) From the above (1) and (4), in a narrow space, it is not possible to fly freely, especially in the upward direction, and the fall is repeated.
The present invention has been made paying attention to the ecology of such flies.

  The attached drawings show the outline of the net structure according to the present invention. In FIG. 1 and FIG. 2, 1 is an outer net, 2 is an inner net, each of which is made by weaving general synthetic resin fibers in a net shape. These are stretched in parallel with each other at an appropriate interval so as to form a shielded space having a predetermined interval. The concept of the outside and the inside is the side where the fly source is located inside. Note that at least both side surfaces of the shielded space are shielded by an appropriate means (not shown) to form a narrow shielded space. This is because the flies will not escape even if the upper side is not shielded from the ecology of the fly. However, as described below, when applying to a window frame, the upper side is inevitably necessary. It may also be shielded. Reference numerals 3, 3... Are flies intrusion holes provided on the entire inner net 2 and are provided in a staggered pattern in the drawing. Reference numeral 4 denotes a bowl-shaped fly reservoir provided in the length direction of the lower end portions of the outer net 1 and the inner net 2, and an opening 4 a is provided facing the space portion between the nets 1 and 2. If a fly falls in this fly pool 4, it will naturally die over time, or if necessary, if you put insecticides such as water, oil, insecticide in this fly pool 4, With the insecticidal component, the fallen fly can be surely controlled.

  In addition, 5 and 5 are spacers provided as needed at predetermined locations between the nets 1 and 2, and when the installation site covers a wide range, the outer net 1 and the inner net 2 that are extended over a wide range. The nets 1 and 2 are prevented from coming into contact with each other so that no slack occurs between them, and a space portion between the nets 1 and 2 is secured. The spacer 5 is provided in the vertical direction because it is necessary to drop the fly as described below.

  The net structure is appropriately provided at a window or entrance / exit of a barn that is a source of flies, but functions as a trap due to the above configuration. That is, the generated flies fly freely in the barn, but enter the shielded space between the outer net 1 and the inner net 2 from the intrusion hole 3 provided in the inner net 2. Due to their ecology, the invading flies will hit the net surface immediately in such a narrow space, and will not be able to fly freely, especially in the upward direction, so they will fall downward. Even if it can stop on the net, it will fly when moving, so it will eventually fall. In addition, even if it jumps up during the fall, it hits the net surface in the same way and falls again. In this case, the probability of jumping out from the intrusion hole 3 is very low. In this way, the flight and the fall are repeated, and finally it falls into the fly reservoir 4 provided at the lower end. The fallen fly cannot fly up again and will die naturally, or if it contains water, oil, insecticides or other insecticidal ingredients in the fly pool, it will die from the insecticidal ingredients. . By such an action, flies generated in the barn can be captured and exterminated by the net structure, and can be prevented from jumping out of the barn, and more reliably eliminated.

  In order to capture more flies, a fly attractant may be applied to both nets 1 and 2. Thereby, many flies are attracted to the net side, and the effect of capture and extermination can be enhanced.

  The net structure will be described more specifically. The net size used and the distance between the nets differ depending on the type of the target fly, but in the case of house flies and fruit flies, both the outer net 1 and the inner net 2 are nets with a size of about 3 mm or less. Use. The distance between the nets 1 and 2 is 50 mm or less. Furthermore, the size of the fly intrusion hole 3 provided in the inner net 2 is about 6 mm to 7 mm in diameter. Further, the interval between the intrusion holes 3 is about 50 mm to 70 mm in the vertical direction and the horizontal direction in the zigzag arrangement as shown.

  In the case of the fly fly, both nets 1 and 2 use nets having a scale of about 1 mm. The distance between both nets 1 and 2 is also set to 30 mm or less. Further, the size of the fly intrusion hole in the inner net 2 is about 3 mm to 5 mm in diameter. The interval between the penetration holes 3 may be approximately the same as described above.

  These specific numerical values are obtained by experiments, but are not definitive, and can be appropriately selected and changed according to the type of the target fly and the installation environment. Needless to say. Moreover, the arrangement | positioning of the penetration hole 3 is not limited to the zigzag arrangement mentioned above, It can arrange | position freely. Furthermore, it is not necessary to arrange them evenly on one side, and considering the ecology that flies do not fly in a high direction, more intrusions 3 may be provided on the lower side than on the upper side. The size of the intrusion hole 3 may be further increased.

  Further, since the spacer 5 is to prevent the slack of the net, it is not necessary to provide it with a small window frame or the like. If the area is large, the installation interval depends on the area of the net to be stretched. Can be appropriately selected. However, since the fly that has entered the shielded space portion is dropped, it is preferable to avoid the horizontal direction and to provide the vertical direction.

  In short, the net structure according to the present invention captures and eliminates flies by double-stretching the nets at appropriate intervals and providing a trap structure by providing flies in the inner net. The range of use is extremely wide, and it can be used in a wide range of places such as cattle, pigs, chickens and other livestock establishments, organic waste processing / processing plants, etc. where flies are generated.

  Also, the specific installation means is not particularly limited. For example, FIG. 3 shows an example in which a net is stretched over the entire window frame of a barn. When it is installed as a window frame, it can be attached so as to be opened and closed like a double screen door, or it can be fixedly attached by fitting a net structure into the frame. Also, not limited to this, means that suspends and installs in places where flies and the like easily come and go, means that installs as a panel by stretching it on a frame, means that creates an opening as a window or screen door Etc. can be widely adopted.

  Since the net structure according to the above configuration captures flies with a physical trap structure in which the nets are stretched doubly, it actively captures and removes flies and puts the flies outside the barn etc. And the number of flies flying can be reliably reduced.

  Further, it is not necessary to apply an insecticide to the surface of the net or impregnate the fiber as in the prior art. Therefore, it can manufacture very cheaply and it becomes possible to save expense. In addition, since no insecticide is used, safety for humans and livestock is very high, and there is no restriction on the installation location.

  In addition, since a net is used, it is possible to obtain sufficient ventilation without interfering with the circulation of inside and outside air in a barn, etc., and the double-structure net appropriately blocks sunlight and obtains a shielding effect. You can also.

  In addition, as described above, installation styles such as a suspension style and a window frame style can be freely selected, and there is a utility that anyone can easily install.

  In addition, when an attractant is applied to the net, it can be expected that the fly can be captured more efficiently.

  Above all, it is possible to surely prevent the flies from escaping outside the barn and the like, so that there is an advantage that it is possible to deal directly with complaints from residents in the vicinity.

  In the above embodiment, the fly prevention and extermination of the fly has been described. Needless to say, the present invention can be applied to other sanitary pests as long as the essence of the present invention is not changed.
