[Detailed description of the invention]

[0001]

[Purpose of the invention]

 The present invention relates to a windbreak net device installed around an orchard, etc., which eliminates the work of climbing up and down the stanchions and opening and closing nets at high places, which is easy for workers to reach. A windbreak net device with a new structure that allows the work to be performed within the range, especially for elderly people and weak women to open and close the windbreak net with safe and easy operation. Is to provide.

[0002]

[Prior art]

 For horticultural farmers who grow 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, thinning, bagging, chemical spraying, and top dressing. Although it is the most important time to reach the end of many agricultural works required throughout the year, it is also the time when a typhoon is likely to land on Honshu, and once a typhoon hits, Due to the strong winds, the branches are damaged and most of the good-quality apples that have been cultivated with great care are destroyed, resulting in enormous damage. This damage is frequently caused not only by typhoons but also by strong winds due to the approach of ordinary low pressure.

[0003] In order to protect the fruit trees from such strong wind blowing, a windbreak net is set around the apple field to protect the fruits from crosswinds by surrounding the apple field with a windbreak net stretched over multiple long columns. It is being appreciated. This windbreak net requires a height of about 5 m, which corresponds to the length of an apple tree, to mitigate strong winds, and must be constructed to ensure adequate ventilation and sunshine during normal times. However, since installation with sufficient wind strength is required, for example, it is sufficient to use scaffolding pipes for construction materials, which are relatively easy to obtain, by columns that are simply inserted directly into the ground. It will be unstable unless it is reinforced with certainty, such as a structure with a large number of retaining pipes.If these retaining pipes increase, not only when constructing a windbreak net, but usually Since it will be an obstacle to the management work of the company, we will entrust a specialized contractor to stand up the special pillars of telegraph pillars at regular intervals, and hang multiple reinforcing wires between these pillars. Prepared footrest Climbing as a ladder, had to the construction of windbreak net to the high altitude.

[0004] The windbreak net thus installed needs to be opened and ventilated to prevent hot air from being trapped in the orchard during the summer season when the wind is relatively weak. It requires a great deal of effort to manage the daily opening and closing of the windbreak net, such as preventing snow from collapsing on the net and collapsing it.In addition, in the event of an emergency such as when a strong wind starts blowing due to the approach of a typhoon etc. If you do not complete the deployment work, you will not be able to avoid damage such as falling, so you have to climb to the top of an unstable prop in strong winds and perform the severe deployment work that you are aware of the danger. There are many cases where this does not happen, and in the case of apple growers, who are aging because they are away from the youth, the daily management of windbreak nets after entrusting them to a specialist contractor has become an extremely difficult problem.

In order to solve such a number of problems, some proposals have been made for an openable windbreak net that allows the windbreak net to be opened and closed on the ground without climbing to a high place. Alternatively, it has become possible to see some apple cultivation farmers' own efforts, but the opening and closing means proposed so far and implemented by each individual person can reach as high a place as possible. Since it is a method to directly operate the windbreak net using a long rod, for elderly people, women and girls who are weak, supporting the long rod is quite a tough work, and especially when facing up. It was immeasurable that I had to walk through the entire opening and closing width of the net.

However, in the case of this type of windbreak facility that is often installed at the boundary of an apple field, the installation location is where the maintenance is usually out of reach or the entire field is an inclined surface. Not only that, there are always risks such as stumps, weeds with long heights, and thick trees that cause them to fall over, resulting in serious injuries, etc. Since it is a work that is unfamiliar to handle with a long rod, it is not difficult for elderly people and women who are weak and it is equivalent to arms, shoulders, legs, waist, etc. It was a situation in which we had to worry that it would be burdensome and would interfere with normal agricultural work.

In view of the conventional opening / closing operation of the windbreak net having the above inconveniences, the inventor of the present application can operate the worker even if the worker is an elderly person or a woman who is incompetent. In addition, there is a need for a practical windshield system that can be opened and closed safely and swiftly without requiring a particularly strong force and without taking an uncomfortable posture. After paying attention to it, we started research and development quickly, and after many trials and errors over a long period of time, we repeated numerous trials and experiments, and as a result, we finally completed the openable windbreak device with a useful and novel structure as described later. The present invention has been successfully put into practical use, and the configuration thereof will be described in detail below together with an embodiment representative of the present invention shown in the drawings.

[0008]

[Structure of device]

 As can be clearly understood from the embodiments representative of the present invention shown in the drawings, the open / close type windbreak device included in the present invention basically has the following configuration. That is, the unit windbreak net is formed to have a predetermined height and width, and one of the left and right edges of the four peripheral edges is integrated with an opening / closing guide rod, and the base end side is a support for embedding in the ground. A wire tensioning metal fitting part, which is formed on the pillar support above the embedding support part and has a reinforcing wire which is stretched around one side of the unit windbreak net at predetermined vertical intervals so as to pass through. It is made up of a predetermined number of pillar tubes that are formed so as to project in the same direction.

Then, the supporting pipes for embedding are embedded in the ground at predetermined places, and the supporting pipes are erected at predetermined intervals substantially corresponding to the lateral width of the unit windbreak net. A reinforcing wire is stretched between the wire tensioning metal fittings at the upper position, but at least the uppermost and the lowermost reinforcing wires except for two of these reinforcing wires have units. Sliding rings, which are arranged at specified intervals at least at the upper and lower edges of the windbreak net, are inserted, and the positions of the two reinforcing wires that do not pass through the sliding ring correspond to their positions. Then, the guide pulleys arranged at the required points of the unit windbreak net and the opening / closing guide rods were inserted in a pendant-like shape that cannot be removed, and from the middle of the upper and lower guide pulleys arranged on the opening / closing guide rods. , Opening and closing guide rods respectively As a result, the towing ropes are separately stretched to the left and right, and the pipes for the columns are located on the stretched side. At the same time, the other edge of the unit windbreak is an open / close windbreak device which is temporarily attached to the corresponding support pipe.

The unit windbreak net is a single layer of a machine-knitted mesh of about 3 to 10 mm or like various known synthetic resin nets for enclosures that have been conventionally used in agricultural work or construction sites. This is a synthetic resin net with a laminated structure, and is determined by the height according to the height of the fruit tree to be protected, the strength of the support tube and the strength and number of reinforcing wires stretched between them. If the width is, for example, an apple or a peach, it is cut into a size of height (3 to 7) m × width (5 to 10) m, and the four peripheral portions are appropriately reinforced with a reinforcing band. The reinforcing string is woven or sewn over the entire width at predetermined intervals in the vertical direction. This unit windbreak net is mainly formed to perform a windbreak function, but in some cases, it is also used or used for a snowbreak net installed along the roadside to prevent snow accumulation on the road. It may be formed as possible.

In this unit windbreak net, at the required points including the highest and lowest positions corresponding to a plurality of upper and lower (usually 4 or more) reinforcing wires stretched between the support pipes, By attaching slide rings such as stainless steel or synthetic resin S rings, and by fitting these slide rings to the corresponding reinforcing wires, the unit windshield is supported by the reinforcing wires. The tensioning structure will be realized, and the reinforcing wire will be used as a guide to be expanded or folded. However, the slide rings that will be attached in correspondence with two of the reinforcing wires stretched around the positions other than the highest position and the lowest position will be described later, instead of the slide rings. It is possible to adopt the same guide pulley as the guide pulley to be attached to the opening / closing guide rod, so that opening / closing and sliding to the left and right can be made smoother.

[0012] The opening / closing guide rod is integrated along the outer side of the edge portion reinforced by a reinforcing band on one of the left and right ends of the unit windshield (that is, the side on which the opening / closing operation is performed), in the vertical direction. When pulling or pushing the edge along with the reinforcing wire, it functions so that the edge can be maintained in a state of being held in a substantially straight line both up and down. In addition to being formed from a lightweight and strong material such as steel pipe or PVC pipe, it is desirable that flange pieces project in the same direction in a continuous manner on the same straight line on the sides or at appropriate intervals above and below. In addition to forming a dedicated member with the flange piece as a connection part to the previous edge, select and adopt the optimum size of existing shape steel and PVC pipe, etc., A separate connecting band is attached to the required points in the vertical direction. However, the connecting band may be attached to and integrated with the edge portion of the unit windbreak net. In addition, holes, hooks and other processed parts, accessory parts, etc. are formed on the opening and closing guide rod side, and they are connected to the corresponding support pipe body by a general temporary attachment means, and the closed state is obtained. The unit windbreak should be prevented from opening or fluttering in strong winds.

In addition, the guide bar for opening and closing is provided with guide pulleys at positions corresponding to two reinforcing wires in the reinforcing wire except for the uppermost and the lowermost in the middle part thereof. The guide pulleys shall not be detachable and should be combined in a suspended manner with respect to the reinforced wire, and the guide pulleys shall be installed in appropriate places between the places where the guide pulleys are attached. The other end of each of the right and left separate traction cords attached to one end is extended substantially horizontally in the direction along the reinforcing wire, and they are placed in advance at the corresponding locations of the supporting pipes on the extension side. It is guided through the direction changing roller or pulley that is installed to the lower part of the supporting pipe to make it hang down. If necessary, it should be placed within the reach of the lower part of the supporting pipe in advance. As each one with the winding part prepared, The hanging end side should be wrapped around those winding parts to keep them organized, and the unit windshield edge on the side where the opening / closing guide rod is attached should be either left or right. When attempting to operate, the unit windbreak net can be opened and closed smoothly by pulling down the hanging end of the tow cord arranged in the operating direction. .

The tow cord may be formed of a durable and flexible cord, such as hemp cord or nylon rope, and the direction and direction of the portion attached to the opening / closing guide rod. Although it is not supported at all between the transfer roller and the pulley, it may hang down, but after the end of the opening and closing operation, hang each hanging end side around the above-mentioned winding part. If this is done, it is possible to maintain a sufficient tension, and it is not necessary to suspend a special support metal fitting or the like from the reinforcing wire and support it halfway. In addition, this pulling operation on the side of the drooping end automatically winds by the drive motor, that is, an endless towing line that connects both the drooping ends. The unit windshield may be configured to be opened and closed by mechanical means by winding the drive motor in the middle and rotating the drive motor in the forward and reverse directions.

The support pipe body has an extremely important function for supporting a unit windbreak net, which receives a strong external force and receives a considerable external force, in a substantially vertical direction at a predetermined position on the wind blow side of the orchard. In order to stand upright on the specified ground with sufficient strength, its base end side must be formed into a buried support that is sufficiently buried and fixed in the ground. Therefore, in order to obtain sufficient bearing capacity in the ground, this embedding support part should be a fin embedding support part with side plates extending radially on its side surface.

[0016] This support pipe body is constructed so that it is driven and embedded into a predetermined ground by a driving machine as appropriate, and is directly supported on the ground. Lowering, paving with crushed stone, etc. to prepare the foundation, and while holding the support for embedding the lower end of the column for the pillar vertically, cast concrete around it and cure and solidify the foundation. It is also possible to support the ground through a section. Needless to say, when the concrete foundation structure is used, it is necessary to take reinforcement measures such as temporary support frames until the concrete is cured and solidified.

A plurality of wire tensions protruding upward in the same direction are arranged on the same straight line on the side surface of the column for the columns vertically erected in this way, at intervals corresponding to the tensioning intervals of the reinforcing wires. Reinforcing wires, which will be described later, are inserted or hooked between the wire tensioning metal fittings at the same height position between the adjacent column pipes for pillars. It is designed so that it can be passed over in a sufficient tension state, and the wire tensioning tool part is such that the reinforcing wire is stretched continuously over a plurality of support tube bodies to create a tension state Structure that allows smooth movement in the direction, such as a ring-shaped suspension ring or a small-diameter short steel pipe that is projected by welding or other means, or is formed by penetrating the support pipe horizontally. Or a structure with through holes formed by Alternatively, it is possible to employ a latching metal fitting or the like provided with a fixing means so that a tension state is realized only between the adjacent column tubes for columns.

The reinforcing wire is stretched in a substantially horizontal shape through the wire tensioning metal fittings which are provided in advance on the supporting pipe body which is erected at intervals according to the unit windbreak width with the above structure. In addition to performing the function of suspending and supporting the above-mentioned unit windbreak net and the function of a guide track for opening and closing the unit windbreak net in the left-right direction, a sufficiently strong material, for example, , Such as a stainless steel wire rope or a metal rope such as a nylon rope, etc., the vertical spacing of the support pipes, the weight of the supporting windshield, and the expected wind pressure are comprehensive. It shall be formed to have a sufficient cross-sectional size that has been taken into consideration.

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 stretched between the supporting pipe bodies is strongly It is possible to pull and fix the reinforcing wire between the pillar tubes while keeping it in tension, and also to make additional winding to adjust the looseness of the reinforcing wire after adjustment appropriately. A wire tensioning device portion is incorporated, and this wire tensioning device portion is formed in a roller winding type having a structure represented by an embodiment described later. In the following, the most representative embodiment will be disclosed and specific description will be made so that the configuration included in the open / close type windbreak device of the present invention described so far can be more clearly understood.

[0039]

[Effect]

 As described above, according to the open / close type windbreak device of the present invention, an opening / closing guide rod that is rollable along a reinforcing wire for reinforcing the net is attached to one side of the unit windbreak net, and Each of the tow ropes branched and extended from this open / close guide rod to the left and right are wrapped around the direction change roller or pulley of the support tube located on the left and right sides and extended downward, Since it is possible to open and close the unit windbreaks only by operating the towing ropes in a very natural posture on the ground, climbing up to the top of the pillar as before. There is no need to install and remove the windbreak net, and workers can use long rods to move the windbreak net to the interior curtain that is being adopted by some workers. Hold and move the net in high places We have realized an open / close type windbreak device that is extremely useful not only for healthy people but also for elderly people and weak women in particular, and can properly manage temperature in orchards and ventilation. Being able to do so has great advantages.

Furthermore, since this open / close type windbreak device is provided with an opening / closing guide rod at the edge of the unit windshield which is the operating side when opening / closing, it secures a strong tension against strong winds and protects against wind. In addition to succeeding in significantly improving the wind performance, it will be possible to easily and reliably maintain the opening in the middle, so it is possible to finely control the ventilation, temperature, etc. The pillar pipe can also be firmly supported in the ground as a support part for embedding with fins, and in particular the concrete pipe is not laid, and the pillar pipe is erected to support strength on the ground itself. This also has the advantage of improving construction efficiency, shortening the construction period, and helping to reduce light costs.
