Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a windbreak / birdproof net shelf for Hasuda, and more particularly to a windbreak / birdproof shelf on a deep mud for lotus cultivation, where there is always water and there is only a narrow ridge. The present invention relates to a structure of a net shelf mainly composed of pipe stanchions for supporting a net laid without exposing a bare pillar.

[0002]

2. Description of the Related Art Conventionally, various techniques have been proposed and implemented to wind a net on a fruit shelf for wind and bird protection, but a net is put on a lotus cultivation mud to prevent lotus leaves from strong winds. There have been few proposals to protect and protect lotus roots from the feeding damage of water birds such as ducks, and most of them leave it up to nature's consequences. It is just a surprise to the duck, and at present Hasuda has no wind and bird protection measures.

DISCLOSURE OF THE INVENTION The present invention can be easily stretched on a lotus cultivation mud and prevents damage of lotus leaves due to strong winds, and also prevents damage to lotus roots caused by water birds, thereby enabling stable cultivation. It proposes a structure of windproof and birdproof net shelves to improve the harvest of lotus root.

[0004]

[Means for Solving the Problems] That is, the present invention provides a foundation pile to be driven into a lotus cultivation mud and a cable supporting pipe band or hook band for inserting and fixing the foundation pile head into a net and stretching the net. A corner pillar composed of the attached upper pillar, a surrounding pillar and a middle pillar are erected at predetermined positions in Hasuda,
A wire cable is stretched in several steps at a predetermined position of the upper pillar, and a net is stretched over the entire circumference side surface and the top surface to surround the whole surface of the Hasuda circle. It relates to the structure of the bird-proof net shelf. Embodiments of the present invention will be described below with reference to the drawings.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION 1 is Hasuda (for example, 54 m × 18)
m) pillars that are erected at the four corners, 2 is a stay pillar that supports the corner pillar 1, 3 is a peripheral pillar that is erected around Hasuda, and 4 is formed by the corner pillar 1 and the peripheral pillar 3. It is a center pillar that is erected at a predetermined position in the center of Hasuda in a rectangular frame.

Next, each pillar will be described in detail. The corner pillar 1, stay pillar 2, surrounding pillar 3 and middle pillar 4 are respectively a foundation pile 5 of the same diameter pipe, and an upper pillar 6 of the same diameter pipe which is inserted and fitted into the head end of the foundation pile 5. The flat cap-equipped short cylinder 10 or the hemispherical cap-equipped short cylinder 11 is inserted into the head end portion of each of the upper pillars 6. A short cylinder 11 with a hemispherical cap is inserted into the head of the middle pillar 4, and the hemispherical cap 11
A through hole for passing the wire cable (semi-steel wire) 12 is provided in the cross shape. Each cap is for preventing damage due to contact of the net 13.

The bottom half of the foundation pile 5 in the lower half of each corner pillar 1, stay pillar 2, surrounding pillar 3 and middle pillar 4 is formed into a flat shape 14 by being crushed so as to be easily driven into the mud. Pillar 1,
On the upper pillars 6 of the upper half portions of 2, 3 and 4, the upper end portion, the middle portion, and the pipe band 7 or the hook band 8 are at the same height.
It is attached to the lower end by bolting.

When the foundation pile 5 and the upper pillar 6 of each of the pillars 1 to 4 are inserted and fitted, a pipe band 7 also serving as a stopper and a wedge 9 having a square bar shape are used to fix the pillar pile 5 and the upper pillar 6 at predetermined positions.

The pipe bands 7 attached to the respective corner posts 1 are fastened by bolt fastening portions 20 at the upper, middle and lower stages of the corner posts. Further, hook bands 8 are bolted to the surrounding pillars 3 at three places in the upper, middle and lower stages of the surrounding pillars.

The corner pillar 1, stay pillar 2, peripheral pillar 3, center pillar 4, foundation pillar 5, upper pillar 6, pipe band 7, hook band 8, square bar wedge 9, etc. are all zinc-dub plated and have excellent corrosion resistance. The wire cable 12 is preferably a semi-steel wire and the net 13 is preferably made of synthetic resin, for example, plastic.

In the windbreak and bird protection facility for Hasuda embodying the present invention, first, the foundation piles 5 of the corner posts 1 are provided at the four corners of the field so that the upper ends of the piles 5 have a certain height above the water surface 17 ( For example, it is driven vertically to about 10 cm from the water surface), then the upper pillar 6 is inserted into the head of the foundation pile 5 for a predetermined length, and the square rod wedge 9
Is fixed by tapping, and the stopper-equipped pipe band 7 also serving as a claw is attached by bolting directly above it.

Next, stay pillars 2 that support the corner pillars 1 are driven into both ends of the rice ridge at a dip angle of 25 to 50 °, and the heads of the stay pillars 2 are connected to predetermined positions of the upper pillars 6 of the corner pillar 1. Fix with metal fittings 19.

Foundation piles 5 for the surrounding pillars 3 are driven in parallel between adjacent corner pillars 1 so as to form a peripheral line, and an upper pillar 6 is inserted and fitted in the same manner as in the case of the corner pillar 1. Then, each upper pillar 6 is erected at the same height so that the surrounding pillars 5 form a square. (Perimeter line)

Inside the field, middle pillars 4 are erected at predetermined positions in parallel with the surrounding pillars 5 at predetermined positions in the same manner as described above.
(Support line)

After the corner pillar 1, the surrounding pillar 3 and the middle pillar 4 are erected at predetermined positions, the claw pipe band 7, which is attached to the upper pillar 6 of each of the pillars 1, 3 and 4 in advance at a predetermined height, With the claws of the hook band 8 with claws as fulcrums, the wire cables 12 are stretched in parallel at the upper end, the middle, and the lower end so as to form a peripheral line and a support line.

Next, a plastic net 13 is hung on the wire cable 12 having a peripheral line to surround the field, and then the wire is stretched around the upper ends of the corner post 1, the peripheral post 3 and the middle post 4. A plastic net 13 is laid on the entire top surface of the cable 12, and the net 13 is stretched over the entire side surface and top surface of the field to complete the wind / bird protection facility according to the present invention. A curtain ring may be attached to the upper and lower edge of the net at the entrance A to the field to open and close in a curtain manner.

Needless to say, the cables 12 and the net 13 are appropriately fixed at predetermined positions by hooks or the like so as not to be blown by the wind. Further, in this embodiment, a plastic net having a mesh of 4 mm was used, but the material, mesh, etc. may be appropriately selected.

[0018]

EFFECTS OF THE INVENTION The present invention is constructed as described above, and because the net can prevent the lotus leaves from strong winds, damage to the leaves is prevented, the growth of the lotus is smoothly promoted, and stable cultivation becomes possible. Also grows well and protects lotus roots from feeding damage of water birds such as ducks, thus improving yield. Further, since each strut pipe is made of zinc dope plated pipe, it has corrosion resistance and the material cost is low, and since the structure of the net shelf of the present invention has a simple structure, even an amateur can easily assemble it.
