2. Description of the Related Art For horticultural farmers who cultivate apples, during the harvest period from mid-August to early November, selection of early spring, artificial pollination after flowering, etc.
The harvest season is the fruitful time of many agricultural works such as flower picking, bagging, spraying of chemicals, and top dressing. However, this time is also the season when a typhoon hits Japan, and once a typhoon arrives, most of the apples that have just been waiting for harvest in good condition without damage will fall out, causing great damage. It is not uncommon to suffer from. Furthermore, the strong winds that cause fruit drop are not limited to typhoons, and fruit drop and branch damage often occur due to strong winds due to the approach of normal low pressure.

[0003] In order to avoid such damage due to strong winds, a windbreak net device that protects fruit trees from strong winds is an indispensable facility for horticultural farmers, and also agricultural crops or plants other than fruit trees, or outdoor equipment products. A relatively tall one also requires a windbreak device. Windbreak devices for dealing with strong winds are widely used, for example, some are installed in highlands or ski areas in mountains, and some are used for safe operation of lifts.
As one example, the windbreak net device and the like disclosed in Japanese Utility Model Laid-Open No. 5-30214 are already known, but the windbreak net device protects the ski lift from strong winds, and therefore the strength of the windbreak net is high. However, it does not have an opening / closing mechanism or the like.

As a windbreak device for use in an orchard, for example, a device disclosed in Japanese Utility Model Publication No. 61-148164 discloses a windbreak device equipped with a winding mechanism that can be opened and closed. There is a structure in which a windproof net can be wound around a vertically suspended roller member and opened if necessary. By allowing the windbreak net to be opened like the one in this known example, it is possible to move and use a large agricultural machine even in the site partitioned by the windbreak screen device, and improve the efficiency of agricultural work. However, when weeding the lower part of the windbreak device, cutting the weeds near the windbreak net with a brush cutter may cause damage to the windbreak net. We were forced to give up, and the weeds that remained were often left unattended, which not only spoiled the appearance, but was not desirable in terms of site management.

The present invention, in the conventional windbreak device having the above-mentioned inconvenience, reviews the opening / closing mechanism of the windscreen device, enables movement and entry / exit of various mechanical devices such as large agricultural machinery, and weeds weeding. I was keenly aware of the need to put into practical use a windbreak device that would enable all over the whole area, and began to develop and research a new opening / closing mechanism, and repeated trial and error over a long period of time and many trial and experiment. As a result, we succeeded in finally completing and putting into practical use a windbreak net device having a novel structure and a windbreak net therefor as will be described later. Hereinafter, the configuration of the present invention will be described in detail together with the representative embodiments of the present invention shown in the drawings.
