Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to the improvement of agricultural nets for protecting fruit trees, agricultural crops, etc. from pests and harmful birds.

(Prior Art) Conventionally, various efforts have been made to protect fruit trees, agricultural crops, etc. from external enemies such as pests and harmful birds.

For example, protective nets (for wind protection, insect prevention, bird prevention, etc.) that utilize the habits of insects and birds have already been devised.

That is, insects and birds have a habit of hating glittering reflected light, and on the other hand, birds have a habit of not descending directly from the sky to feeding grounds.

In other words, birds always descend nearby and check their surroundings before flying down to the feeding area.
In addition, when looking at a feeding area from above, they have a habit of being wary of places with irregular lighting (reflected light) and not descending. For example, reflectors such as mirrors are attached to fields or protective nets, or protective nets covered with aluminum foil or the like are stretched around or on top of agricultural crops.

In addition, scarecrows, alarm bells, and other threatening devices were installed to intimidate pests and harmful birds, while insect control methods using pesticides and hormone secretions were also popular.

(Problems that the invention attempts to solve) However, in the case of these conventional ones,
Not only is there a problem in that it is necessary to install a separate mirror (reflector), a warning device such as a sounder, or coat it with aluminum foil, and it is also expensive. It used to be time-consuming to collect reflectors and sounders.

Furthermore, since the reflectors arranged are individual and have no relation to each other, they do not sparkle in conjunction with each other as a whole, and the effect of intimidating pests and harmful birds is poor.

Additionally, if a separate reflector such as a mirror is attached to the protective net, the weight of the reflector may cause the net to loosen or break, and the overall weight may increase.
There was a problem where the net could not maintain tension.

On the other hand, recently, natural foods such as pesticide-free vegetables have been reconsidered, and there has been a demand for inexpensive agricultural nets that can prevent pests and harmful birds without using pesticides.

The present invention has been developed in view of these conventional problems and demands, and aims to provide a net for insect and bird prevention and agricultural use that has an extremely effective intimidating effect on insect pests and harmful birds using an inexpensive and extremely simple means. The purpose and gist of the net is to create a windproof, heatproof, or light-shielding agricultural net knitted with warp and weft yarns, and to incorporate a plurality of reflective patterns by weaving synthetic resin silver threads into the net body. It is present in the installed insect and bird prevention and agricultural nets.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems and achieve the intended purpose, the insect-proofing and bird-proofing net of the present invention for agricultural purposes uses synthetic resin silver thread woven into the net body. They placed multiple reflective patterns on the wall.

(Function) The insect-proofing and bird-proofing and agricultural net constructed in this way has a plurality of reflective patterns woven into the net body by weaving synthetic resin silver threads into it, so that it can be used as a separate mirror or as an agricultural net. Since it does not require the installation of a sounder or the application of aluminum foil, there is no need to install or place a reflector or store a net.
In addition, since silver thread is integrally woven into the main body of the net, when the net is swayed by the wind, the multiple reflective patterns will interlock and sparkle.

(Example) Next, an example of implementation of the present invention will be described with reference to the drawings.

In the figure, A is the insect-proofing, bird-proofing and agricultural net according to the present invention.
is knitted with warp yarns 1 and weft yarns 2 formed by warp knitting (ratssel stitching) of polyethylene or filament yarns. Then, at an appropriate location on Net A,
For example, a silver thread 3 made by forming a thin paper-like silver film made of synthetic resin into a long and thin strip is machined (not shown).
A plurality of appropriately shaped reflective pattern bodies 4 are interwoven with each other and arranged in a scattered manner. As shown in FIGS. 1 and 2, the reflective pattern body 4 has a substantially rhombic shape or a lightning bolt shape. Although FIGS. 1 and 2 show an example in which the reflective patterns are regularly arranged, they may also be arranged in a dotted manner at appropriate positions as described above. In addition, since the silver thread 3 is formed into a belt shape, light is easily reflected, and when the reflective pattern body 4 is knitted, the silver thread 3 is twisted appropriately to knit the pattern. The reflective pattern body 4 shines well.

Further, a support string 5 is inserted into the end of the net A.

(Effects of the invention) The present invention is constructed as described above, and by arranging a plurality of reflective patterns by weaving synthetic resin silver thread into the net body, it is possible to create a separate mirror (reflector) and a sound. There is no need to attach a sound device or cover with aluminum foil, and there is no need to attach or collect a reflector or a sound device, or store a net, as in the past. It has now become possible to provide a simple and inexpensive net for insect and bird prevention as well as agricultural use. Since the shape of the reflective pattern body is formed into a substantially diamond shape or a substantially lightning bolt shape, the stimulation given to birds etc. is greater than when the reflective pattern body is arranged in a band shape. Also,
Since multiple reflective patterns are arranged in a scattered manner,
The reflective pattern shines irregularly and can be effectively intimidating. In other words, birds and the like can be permanently threatened without becoming accustomed to the reflective pattern. Furthermore, because the silver thread is woven into the net body,
Conventionally, when the net is swayed by the wind, the multiple reflective patterns arranged all over the net sparkle in conjunction with each other, which has a tremendous effect of intimidating pests and birds, and the weight of the reflectors can cause the net to loosen or break. This problem was also resolved.

Furthermore, since the structure is simple, it is suitable for mass production and can be supplied to customers at a low price.

As described above, the present invention has excellent advantages, and implementing the present invention has enormous practical value.
