2. Description of the Related Art For horticultural farmers who cultivate apples, the harvest period from mid-August to early November begins with fertilizer work in the winter of the previous year, pruning in early spring, artificial pollination after flowering, flowering, bagging, and chemicals. Although it is the most important time to reach the end of a lot of agricultural work such as spraying and top dressing, which is required throughout the year, it is also the season when a typhoon is likely to land on Honshu, and once If this is done, the strong wind will cause damage to the branches, and most of the good-quality apples that have been cultivated will be depleted, resulting in immense damage. This damage is frequently caused not only by typhoons but also by strong winds due to the approach of normal low pressure.

[0003] In order to protect the fruit trees from such strong winds, it is necessary to install a wind avoidance facility that protects the fruits from strong winds by surrounding the apple field with a wind avoidance net stretched over a plurality of long columns. Has been done. This wind avoidance net is
It must be stretched to a height suitable for the length of the apple tree to soften strong winds, and in normal times, it must be constructed so as to ensure proper ventilation and sunshine, and it has sufficient wind pressure resistance. Since it is necessary to install it as a facility with a structure, for example, it is extremely unstable in a facility that only combines scaffolding pipes for construction materials, which are relatively easily available, with columns that are simply inserted directly into the ground. Since there is a risk that it will collapse due to strong winds, in most cases it is necessary to construct a structure with a considerable number of backup pipes installed diagonally. Not only will the construction itself become very complicated, but it will also be a hindrance during normal management work, so instead of these structures, we will entrust a specialized contractor exclusively and place the special pillars that are robust in the form of telegraph columns at predetermined intervals. Standing up , You have to rely on costly work due to special construction, such as straddling a reinforcing wire between those columns, climbing the footrests prepared in advance on the special columns as a ladder, and attaching a wind shield net to high places. Didn't get

[0004] The wind avoidance net thus installed must be managed in the orchard so that hot air does not accumulate in the orchard during the summer when the wind is relatively low. In winter, it is necessary to put everything around the stanchions in order to prevent it from falling and falling on the windbreak net, so that much effort is required to manage the daily opening and closing of the windbreak net. In addition, in an emergency such as when a strong wind begins to blow due to the approach of a typhoon or the like, strong winds are approaching because it is not possible to avoid damage such as fruit drop unless the work of deploying the wind avoidance net is completed promptly. In some cases, it may be necessary to climb to the top of an unstable stanchion and carry out rigorous deployment work that is aware of the danger. Windshield after installation Also in the management plane of the net, it has become a situation that faced an extremely difficult problem.

To address many of these problems,
Several proposals have been made for the wind-proof net with an improved structure that allows the wind-opening net to be opened and closed on the ground without climbing to high places, or implemented by the apple growers themselves. However, the opening and closing means of the wind-prevention net in facilities that have been proposed or implemented by individual ingenuity should be long rods that reach as high a place as possible. It is a very difficult work for elderly people, women and girls who are weak, because it is operated by directly pushing or pulling the high place of the wind avoidance net, especially while continuing the upward and impossible posture, The work of walking and moving through the entire opening and closing space of the net was not only fatigue but also sometimes dangerous.

[0006] In other words, in the case of this type of wind avoidance facility that is often installed at the boundary of an apple field, the installation location is a place where maintenance is usually not well done, or the entire field is an inclined surface. Not only that, there are always risks such as stumps, weeds with long heights, thick trees, etc. that cause you to fall, resulting in serious injuries, etc. Since it is a task that you are not familiar with from the usual operation of long rods, not only for weak elderly people and women and women, but also for workers who are full of work, arms, shoulders, legs, waist, etc. I had to worry that it would impose a considerable burden that I would rarely experience, and that it would interfere with normal agricultural work.

In view of the above-described inconvenience of opening and closing the wind-preventing net, the inventor of the present invention can operate even if the worker is an elderly person or a woman who is incompetent. , I strongly felt the need to put into practical use a wind-prevention facility that enables safe and quick opening and closing work of the wind-preventing net without requiring a particularly strong force and without taking an unreasonable posture. As a person who has been asked to set up a traditional facility from the past, he quickly started developing and researching, and as a result of repeating trial and error over a long period of time, many trials and experiments were repeated, and this time, it is extremely useful as described later The unit has completed and put into practical use a wind shelter, which consists of a new method for opening and closing the unit wind shelter net of the wind shelter, and a new structure for implementing the method. In the following, the details of the configuration will be explained together with the embodiments representative of the present invention shown in the drawings.

[0008]

As clearly understood from the typical embodiment shown in the drawings, the unit wind avoidance net opening / closing method of the wind avoidance facility included in the present invention basically has the following constitution. It is a summary. That is, a unit wind-preventing net, which is formed to have a predetermined height and a horizontal width and is integrally formed with an opening / closing guide rod at any one of the left and right edges of the four peripheral edges, is used for a column that is erected at predetermined intervals. A plurality of reinforcing wires stretched between the pipes are hung on one side of the reinforcing wire so that they can be freely circulated. The other end of the unit wind avoidance net is temporarily attached to the corresponding support pipe. In the wind-prevention facility, each of the unit wind-preventing nets has one edge formed by integrating the opening / closing guide rod, and the towing ropes are separately extended to the left and right with the opening / closing guide rod as the starting end. Further, only by pulling down the tow line on either side that has reached the lower part of the support tube through a direction changing roller or pulley arranged at a predetermined position on the support tube located on the extended side. A unit that can be opened and closed and is open or closed up to a predetermined position With the avoidance net in that state, the left and right towing ropes are tensioned together and temporarily fixed by winding or other means at appropriate places below the corresponding supporting pipe body, and the unit is adjusted to the desired opening degree. It is a unit wind-preventing net opening and closing method of a wind-preventing facility, which is characterized in that a wind-preventing net is held.

[0009]

[Related Invention 1] In relation to the unit wind avoidance net opening / closing method of the above-described wind avoidance facility of the present invention, a wind avoidance facility having the following configuration is also for effectively implementing the opening / closing method. It is included in this invention as a windbreak facility. That is, a unit wind-preventing net, which is formed to have a predetermined height and a horizontal width, and an opening / closing guide rod is integrated with one of the left and right edges of the four peripheral edges, and the base end side is a support for embedding in the ground. A predetermined number of wire tension metal fittings, which are formed in a portion and are inserted through a reinforcing wire that is stretched around the one side of the unit wind avoidance net at predetermined vertical intervals above the embedding support portion. , Which is composed of pillar tubes formed by projecting and forming in the same direction, embedding the embedding support part in the ground at a predetermined location and standing at a predetermined interval approximately corresponding to the width of the unit wind avoidance net. While the reinforcing wires are stretched between the wire tensioning metal fittings at the corresponding height positions of the supporting pillars, the two reinforcing wires in these reinforcing wires are connected to the unit wind avoidance net. On the part corresponding to those of the opening and closing guide rod integrated on one edge The guide pulleys are inserted into the suspension so that they cannot be removed and are suspended, and from around the middle of the pair of upper and lower guide pulleys, the pulling cords are separately extended to the left and right with the opening and closing guide rods as the starting ends. On the side of the column for the support column so as to reach the lower part of the column for the column via the direction change roller or pulley arranged at a predetermined position, and for all other or limited reinforcing wires, the unit This is a facility for avoiding wind that consists of a ring for sliding that is placed in the required location of the wind-preventing net.

That is, unit wind-preventing nets each having a predetermined height and width and having an opening / closing guide rod integrated with one of the left and right edges of the four peripheral edges are erected at predetermined intervals. A plurality of reinforcing wires stretched between the support pipes are suspended and slidably installed on one surface side, and the other end of the unit wind avoidance net is temporarily attached to the corresponding support pipes. In such a wind-preventing facility, each of the unit wind-preventing nets has one end formed by integrating the opening / closing guide rod, and the pulling ropes are separately provided to the left and right with the opening / closing guide rod as the starting end. Stretching, and further extending to the side of the strut tube Pulling down the tow line on either side that has reached the bottom of the strut tube through a direction-changing roller or pulley placed at a predetermined position. It can be opened and closed by just operating it, and it opens or closes to a specified position. With the unit wind avoidance net in that state, the left and right towing ropes are tensioned together and temporarily fixed by winding or other means at appropriate places below the corresponding support tube body, which is desired. This is a unit wind avoidance net opening / closing method of a wind avoidance facility, characterized in that a unit wind avoidance net is held at the opening.

In this unit wind avoidance net, at the essential points including the highest and lowest positions corresponding to a plurality of upper and lower (usually four or more) reinforcing wires stretched between the support pipes, Slide rings such as S rings made of stainless steel or synthetic resin were attached, and by fitting these slide rings to corresponding reinforcing wires, the unit wind avoidance net was supported by the reinforcing wires. A tension structure is realized so that the reinforcing wire is used as a guide so that it can be spread or folded. However, the slide ring to be attached corresponding to two of the reinforcing wires stretched around the positions other than the highest position and the lowest position may be replaced by those slide rings depending on the case, and the opening and closing described later. It is possible to adopt the same guide pulley as the guide pulley to be attached to the guide rod for use, so that opening and closing and sliding to the left and right can be performed more smoothly.

The opening / closing guide rod is integrated along the outer side of the edge portion reinforced by the reinforcing band on one of the left and right ends of the unit wind avoidance net (that is, the side on which the opening / closing operation is performed), in the vertical direction.
When pulling or pushing the edge portion along with the reinforcing wire, the edge portion functions so that the edge portion can be maintained in a state of being held in a substantially straight line both up and down. It is made of a lightweight and strong material such as square steel pipe or PVC pipe, and it is desirable that the flange pieces project in the same direction on the same straight line in a continuous form or with vertical gaps at appropriate intervals. In addition to forming the flange piece into a dedicated member that serves as a connection part to the previous edge, select and adopt the optimum size of existing shape steel and PVC pipe, etc. It is also possible to attach a separate connecting band at a required point in the direction and to attach and integrate to the edge portion of the net by the connecting band to avoid unit wind.

Further, the guide bar for opening and closing is provided with guide pulleys at positions corresponding to two reinforcing wires in the reinforcing wire excluding the uppermost position and the lowermost position in the middle thereof. With respect to the reinforcing wire, these guide pulleys are designed so that they cannot be removed and are combined in a suspended manner, and from the appropriate places of the guide rods for opening and closing located between the places where these guide pulleys are attached, The other end of each of the left and right separate traction cords attached to the opening / closing guide rod is extended substantially horizontally in the direction along the reinforcing wire, and each of the support pillars is located on the extension side. Guide through the direction changing roller or pulley that has been installed in advance at the corresponding location to guide it downward to form a hanging shape. Use the winding part in advance within the reach of As a result, each of the hanging end sides was wrapped around those winding parts to keep them organized, and the unit wind avoidance net edge on the side to which the opening / closing guide rod was attached, When trying to operate in either the left or right direction, the towing ropes arranged in the operating direction
By pulling the hanging end downward, the net for avoiding unit wind can be smoothly opened and closed.

The tow line may be made of a durable and flexible cord, for example, hemp cord or nylon rope, and the direction change from the portion attached to the opening / closing guide rod. It is not supported between the roller and pulley for use at all, and there is no risk that it will hang down.However, after finishing the opening and closing operation, pull down both hanging end sides and then attach it to the above-mentioned winding part. If it is wrapped around, it can be maintained in a sufficiently tensioned state, and it is not necessary to suspend a special supporting metal fitting or the like from a reinforcing wire or a wind-proof net to support the midway. In addition, the pulling operation on the side of the hanging end is an automatic winding mechanism that automatically winds by the drive motor, that is, an endless towing cord that connects both of the hanging ends. And wrap it around the drive motor, and rotate the drive motor forward,
It is also possible that the unit wind avoidance net can be opened and closed by mechanical means by performing a reverse operation.

The support pipe body plays an extremely important function for supporting the unit wind avoidance net, which receives a strong external force and receives a considerable external force, in a substantially vertical manner at a predetermined location on the wind blow side of the orchard. The member, the base end side of which must be sufficiently embedded and fixed in the ground so as to be erected on the predetermined ground with sufficient strength, From the viewpoint of handling the member and burying the member, the embedding support portion is formed separately from the strut body protruding upward, and the lower portion of the strut body is fitted or inserted into the embedding support portion. It should be constructed so that it can be used as a support pipe body, and in order to obtain sufficient bearing strength in the ground, this buried support part Fins with fins extending radially on the side It should be embedded supporting section come.

This burying support portion is constructed so that it can be struck and buried in a predetermined ground by a placing machine as appropriate, and it is directly supported on the ground. In addition, a setting hole is dug down at a predetermined position of the ground to crush stone Etc. are laid out and grounded, and while this embedding support is held vertically, concrete is placed around it and cured and solidified to be supported by the ground through a strong foundation. It is also possible to do so. Even in the case of a pillar pipe in which the embedding support part is integrally formed below the strut body, the support and integration of the embedding support part to the ground are the same as those of the above-mentioned divided and formed structure. So that it is embedded and fixed. However, in the case of embedding and fixing one pillar pipe, and using a concrete foundation structure, it is necessary to take reinforcement measures such as a temporary support frame until the concrete is cured and solidified. is there.

On the same straight line of the side surface of the column for the pillars thus erected in this manner, a plurality of wire tensions protruding in the same direction are vertically arranged at intervals according to the tension of the reinforcing wires. The metal fittings are projected and formed, and between the wire tensioning metal fittings at the same height position between the adjacent pillar tubes,
Reinforcing wire, which will be described later, is inserted or hooked so that it can be hung over in a sufficiently tensioned state. A structure that allows smooth movement in the axial direction so that it can be tensioned by being stretched on, for example, a ring-shaped suspension ring or a small diameter short steel pipe is projected by welding or other means. It may be formed into a structure, or a structure with a through hole formed by penetrating the support pipe in the horizontal direction, or fixed so that a tension state is realized only between adjacent support pipes. It is possible to adopt a hooking metal fitting or the like provided with the means.

The reinforcing wire is stretched in a substantially horizontal shape through the wire-stretching metal fittings which are provided in advance on the supporting pipes which are erected at intervals according to the unit wind avoidance net width with the above structure. In addition to performing the function of suspending and supporting the above-mentioned unit wind avoidance net, and also performing the function of a guide track when opening and closing the unit wind avoidance net in the left-right direction, a material of sufficient strength, For example, a metal rope such as a stainless steel wire rope or a nylon rope may be used, and the spacing between the columns for the columns, the weight of the unit wind avoidance net to be supported, and the expected wind pressure, etc. It must be formed with a sufficient cross-sectional size that is comprehensively considered.

The temporary fixing metal part is integrated with one side edge which is an opening / closing operation side of the unit wind avoidance net when the unit wind avoidance net is completely spread between the support pipes. The open / close guide rod is temporarily attached to the side surface of the supporting column that is drawn into contact with it, and the unit wind avoidance net in the expanded state is flared by strong wind or pulled back to avoid wind. It is a metal fitting that functions so as not to lose its function, and a temporary attachment structure that can temporarily fix the opening and closing guide rod, for example, a retaining pin that holds the cross section of the opening and closing guide rod and prevents it from coming out By combining them, the structure represented by the embodiment described later, or the structure in which a belt is wound around and stopped, and further, a vice lever is rotated and operated. Outside such shall opening and closing induction rod structure to become held in 挾着 shape, hole or hook other processing unit to open and close the induction rod side, accessory bracket portion or the like is formed,
It has a structure in which the metal fittings attached to the support pipe are fitted, dropped, meshed or combined with other general temporary attachment means. As described above, it is attached to a predetermined position of the supporting pipe body by a separate band, or is integrally formed at a predetermined position below the supporting pipe body by a strong fixing means such as welding. I shall. In addition, this temporary fixing metal part secures a temporarily attached state in which it is attached to the side of the support tube body of the opening / closing guide rod by allowing temporary attachment at two places along the opening / closing guide rod. be able to.

On the other hand, at the height position where the operator can reach below the required supporting pipe body in the supporting pipe body, one end side of the reinforcing wire that is stretched between the supporting pipe bodies is strongly A wire that can be pulled to fix the reinforcing wire between the column tubes for each column while maintaining the tension state, and can be additionally wound to properly adjust the looseness of the reinforcing wire after adjustment. It would be extremely convenient if the tensioning device was incorporated.

This wire tensioning device section is of a roller winding type as typified by an embodiment described later, and a weight of a predetermined weight is hung at the end of each reinforcing wire. Always pull the reinforcing wire downward so that the tension is maintained, or connect the end of the reinforcing wire to the end of the pull-in lever or bolt to move the screw of the bolt to the nut forward or backward. The reinforcing wire is moved forward and backward by means of it, and further, the winding portion is provided with engaging means such as a hook wheel in only one direction, and is composed of a notch feed mechanism capable of rotating only in the winding direction. It is possible to adopt a known winding structure as appropriate.
