Abstract

<P>PROBLEM TO BE SOLVED: To provide an apparatus for attaching a bird-preventing net by which attaching operation of the bird-preventing net can extremely smoothly and rapidly be carried out and height suitable for bird-preventing effect and height suitable for farm operation can readily and surely be ensured in order to solve problems in which it was not easy for operators to enter the inside of a net which was spread all over and carry out operation and it was difficult for operators to carry out smooth and rapid stretching installation of a net body, because the net body is formed so as to be fixed to the top end of a strut, though bird-preventing nets for preventing damage from various birds causing damage to farm products of fields, etc., have widely been used hitherto. <P>SOLUTION: The apparatus for attaching the bird-preventing net is constructed by installing pillar-receiving parts 2 in the inside centers of disks 1 in which a circular arc surfaces and a smooth surfaces are formed in the upper surface parts and fitting struts 4 each having an adequate length into these pillar-receiving parts 2 and stretching net bodies 5 to upper surface parts of discs on many struts installed in a prescribed place. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an attachment device for a bird net.
[0002]
[Prior art]
The use of bird nets against a variety of birds that damage crops such as fields has become widespread, but it has not been easy to work under a stretched net, and the net is the top of the column. Since it is fixed to the part, it has been difficult to smoothly and quickly stretch the net.
[0003]
Conventionally, as a bird-proof net used in orchards, a device such as utility model registration No. 3091415 is known (see Patent Document 1), which is a branch line erected from a vertical and horizontal direction on a cap into which a column is inserted. Since it was penetrated and supported by inserting a column from below, it was difficult to smoothly and quickly stretch the mesh body, which took time and effort.
[0004]
[Patent Document 1]
Registered Utility Model No. 3091415 (FIG. 3, paragraph number 0005)
[0005]
[Problems to be solved by the invention]
Therefore, the present invention provides a device that can perform the work of attaching the bird nets very smoothly and quickly, and can easily and surely secure the height suitable for the bird-proof effect and the height suitable for the farm work. It is intended to provide.
[0006]
[Means for Solving the Problems]
In the present invention, a pillar receiving portion is provided at the center of the inside of a disk whose upper surface portion forms an arcuate surface and a smooth surface, and a pillar having an appropriate length is fitted therein, and a plurality of pillars installed at predetermined positions are mounted. A net is stretched over the upper surface of the disk.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Now, after the disc is fitted on the pillars arranged in the central part of a predetermined field or the like and a peripheral part with an appropriate interval, a predetermined net is stretched over the upper surface of the disk. As a result, the nets placed on the upper surface of each disk come to stick together by appropriately adjusting the overall tension while sliding well on the disk surface.
[0008]
There is no problem in farming inside the net that has been stretched in this way because the height of the support can be changed to a height that a person can fully put in, and there is no bird protection effect after the work. It can be returned to a suitable height.
[0009]
【Example】
Reference numeral 1 denotes a disk whose upper surface portion is composed of an arcuate surface and a smooth surface. A column support portion 2 is provided at the inner center of the disk, and reinforcing ribs 3 are provided around the column support portion.
[0010]
Reference numeral 4 denotes a support column having an appropriate length for fitting the upper end portion to the column receiving unit 2, and this support column is detachable.
[0011]
The material of the support 4 is not limited, and natural bamboo may be used. Further, the support column 4 may be configured to be adjustable in a telescopic manner.
[0012]
FIG. 5 shows an example of the construction state in the field, but the discs 1 are fitted to the center of the field of a predetermined area and the top ends of the columns 4 standing at an appropriate interval around the center. After that, a predetermined net 5 is placed on the upper surface of each disk and stretched.
[0013]
The peripheral edge of the mesh body is fixed to the ground by a stator 6... This stator is free so that it can be moved up and down, and can be fixed at an arbitrary height position. To.
[0014]
【The invention's effect】
Since the present invention has such a configuration and operation, when installing a bird net for a farm product such as a predetermined field, a net covering a large area is placed on the upper surface of each disk. As a result, it can be smoothly adjusted while sliding freely, so that the whole can stick to a moderate tension, and the whole net can be attached with an average good tension.
[0015]
Moreover, since the height position of the net on the support can be freely changed so that a sufficient space for farming work is secured under the net, there is no problem in working inside the net.

Claims (1)

A pillar support is provided at the center of the inside of the disk whose upper surface forms an arcuate surface and a smooth surface. A bird net installation device characterized in that a net is stretched over the section.
