Description

[Detailed Description of the Invention] This invention mainly relates to a net for covering all or part of the trees in an orchard from a high place to protect the fruit from damage by insects, birds, etc., and its purpose is to: To provide an insect-proof and bird-proof net for a field, which can be attached to a shelf assembled in a field with a uniform tension over the entire area without bending the net, and which is easy to attach and remove. be.

In recent years, fruit cultivation has been susceptible to damage from birds, insects, and electricity, so shelves have been built above the fruit shelves, and covered nets shaped like mosquito nets have been pasted onto the shelves.

However, the fields are large, ranging from about 30 to 50 are, and the racks on which the nets are hung are 3 to 4.5 meters high, requiring a lot of manpower to hang the large nets shaped like mosquito nets. However, in snowy regions, snow accumulates on the ceiling and accelerates the aging of the net, so it is not recommended to use the net in winter. It was extremely difficult to remove and install, requiring time and effort each time.

In addition, this type of net has a large area and is often installed in sections, but it is still large and long and may be bent when pasted, making it troublesome to handle.

Therefore, the present invention has been developed in order to address the above-mentioned conventional difficulties.Explaining the embodiment with reference to the drawings, the present invention includes a ceiling net 2 of a covering net 1 formed in the shape of a mosquito net, and a side net covering each side. 3 are formed separately, and the joints where the ceiling net 2 and the side net 3 are connected to each other extend from the ridge of the net 1 to the side surface when they are combined to form the covering net 1. The fastener stringers 4 and 5 are installed so that they are located in a slightly drooping part and are all in the same plane over the entire length of each joint edge, and both fastener stringers 4 and 5 are attached to the slider 13. The ceiling net 2 and the side net 3 are connected by a slide fastener 6 which can be engaged and releasably engaged with each other. It can be completely separated.

The above structure is constructed based on the basic idea of this invention, and as an example of its implementation, as shown in FIG. 1, the ceiling net 2 is divided into a plurality of unit nets 2a, and each unit net 2a is The side nets 3 have a predetermined length on each side, and the ends of each side net 3゜3 are connected to each other by a slide fastener 8 with a releasable fitting. They are connected by a slide fastener 9 with a releasable fitting at the corner of the direction.

In addition, the slide fasteners 8 that connect the unit nets 2a of the ceiling net 2, the slide fasteners 6 that connect the ceiling net 2 and the side nets 3, and the slide fasteners 9 that connect the side nets 3, 3, respectively. By arranging them by color and distinguishing the ceiling net 2 and side net 3 according to the color, handling of each set 2 and 3 becomes easier.

Further, as a structure in which the ceiling net 2 and the side net 3 in the above-mentioned embodiment are connected by a slide fastener 6, as shown in FIG.
Install the fingers 4 and 5 so that they are all on the same plane,
The interlocking elms 6a are placed in a position slightly hanging down from the main line 11 of the shelf provided in the field.

In addition, as shown in FIGS. 3 and 4, the ceiling net 2 or side net 3 is supported by wrapping it around the trunk line 11 of the shelf at the joint edge of the ceiling net 2 or side net 3. In some cases, a water stop member 12 is provided.

In addition, as a means for fixing the water stop member 12 to the main line 11, it is preferable to fasten it with a hook (see FIG. 3) or tie it with a string (see FIG. 4).

Furthermore, it is desirable that the slider 13 of the slide fastener used in the net of the present invention be made remotely controllable by attaching a long string for operating the slider as illustrated in FIG. It is preferable to attach two strings to the slider of the slide fastener connecting the two.

The string of the slider 13 is used not only for operating the slider, but also as a presser for the net that has been set up.

This invention has the above structure, and when the covering net 1 is hung on a shelf installed in a field, each unit net 2a on the ceiling is spread out on the ceiling of the shelf, and each set 2a is connected while the covering net 1 is placed on the ceiling. 2 on the ceiling surface, and by combining the fastener stringers 4 of the ceiling net 2 with the fastener stringers 5 of the side net 3 and meshing with each other, the side net 3 can be pasted on the side of the shelf according to the meshing. be.

Also, when connecting to the structure shown in Fig. 3 or 4,
After the side net 3 is fixed to the main line 11 via a water stop member 12, the ceiling net 2 is stretched and connected to the side net 3.

As described above, the insect-proof and bird-proof net for agricultural fields according to the present invention has the ceiling net and side net of the covering net formed in the shape of a mosquito net formed as separate bodies, and the joining part of the side net is connected to the covering net. The side net is installed at a position hanging down from the ridge, and the side net is connected so as to be openable and closable using a slide fastener with a releasable fitting. The joints of the nets are reliably connected in a uniform state without bending over the entire length, and each set is pasted with a uniform tension over the entire surface without wrinkles.

In addition, since both the fastener stringers attached to the ceiling net and the side net are all on the same plane, the engagement and opening operations using the sliders can be performed smoothly even under the load of the side net. Furthermore, after the meshing, the joint between the ceiling net and the side net is reliably closed without any meshing cracks.

Furthermore, the connected slide fasteners are linear and are formed in a position that hangs down slightly from the edge of the shelf, so this slide fastener has a kind of regular role and is not suitable for shelves. The positional relationship between the ridge and the slide fastener makes it obvious at a glance whether the covering net is properly or abnormally attached, and this allows the net to be attached normally without bending.

Additionally, since the joint is a slide fastener, the joint can be closed reliably and insects can be prevented from entering through the joint.
