防鳥糸張り器

Implement for stretching bird-repellant yarn

Abstract

【課題】 雀、烏等鳥害を防止する為には 作物の上30〜50cmの高さに鳥害防止用ポリエチレン防鳥糸を50〜60センチ間隔程度で多数引っ張る事が抜群の効果がある しかし糸張り方法に効果的なものがない 多数の糸を 同時にス厶ースに農家の誰にでもやさしく簡単に 糸張りの出来る事が課題である 【解決手段】 100mに及ぶ長田等で10本以上多数の糸を同時に引っ張る為には 防鳥糸ボビンが同時に適度に回転し過回転による糸の弛みが軸に巻き付く故障を除去する必要がある ボビンの上,下にゴム板を取り付け 簡単なネジの調整による摩擦制動を利用することがやさしくて 誰にでも出来る効率的な手段である
PROBLEM TO BE SOLVED: To enable every person of farmers to easily and simply stretch many of yarn for preventing bird damage smoothly at the same time, by solving such a problem that there have never been effective methods for stretching the yarn, while stretching many of polyethylene bird-repellant yarn for preventing the bird damage at intervals of about 50-60 cm in spaces higher than crops by 30-50 cm is extremely effective for preventing the bird damage caused by sparrows, crows, etc. SOLUTION: A means by which the every person can easily and effectively stretch the yarn is so formed that rubber plates are attached to the top and bottom of each of bobbins, and friction brakes on the plates are easily utilized by simply adjusting screws, because it is simultaneously required that the bobbins of the bird-repellant yarn are suitably rotated and a trouble of winding and entangling of the loosened yarn around a shaft of the bobbin due to an over rotation speed is prevented, for the purpose of stretching many threads of the yarn, such as ten or more threads over a long paddy field, etc., having a length of up to 100 m.
