2. Description of the Related Art For a horticultural farmer who grows apples, the harvest season from mid-August to early November starts with the original fertilizer work in the winter of the previous year, pruning in early spring, artificial pollination after flowering, flowering, bagging, chemicals. Although it is the most important time to reach the end of many year-round farming activities such as spraying and topdressing, it is also the season when the typhoon is likely to land on Honshu, and once it hits the typhoon If this were to happen, the strong wind would cause the damage to the branches, as well as most of the good-quality apples that had been bred carefully, resulting in enormous damage. This damage frequently occurs not only due to a typhoon but also due to a strong wind caused by the approach of a normal low pressure.

[0003] In order to protect the fruit trees from the blowing of such strong winds, it is necessary to install a windbreak facility surrounding the apple field with a windbreak net stretched over a plurality of long columns to protect the fruits from strong winds. Is being done. This windbreak net
It must be stretched to a height appropriate to the length of the apple tree to mitigate strong winds, and in normal times it must be configured to ensure adequate ventilation and sunshine. For example, it is extremely unstable in a facility that combines scaffolding pipes for construction materials, which are relatively easily available, with pillars that are simply inserted directly into the ground because they need to be installed as dedicated facilities. In such a case, a considerable number of stay pipes must be installed in a slanted structure. Not only will the construction itself become very complicated, but it will also become a disturbing facility during normal management work. Erected in , Laying a reinforcement wire between those pillars, climbing the footrest prepared in advance on the special pillar as a ladder, attaching a windbreak net to high places, etc., and relying on expensive work in special construction. Did not get

[0004] In the summer when relatively strong winds are lessened, it is necessary to open the entirety of the windbreak nets installed in this way to allow the wind to pass through and keep the orchard free of hot air. In winter, we put a lot of effort on the daily opening and closing management of the windbreak net throughout the year, such as keeping everything around the pillars and tying it to prevent snow falling on the windbreak net and collapsing In addition, in the event of an emergency such as when a strong wind starts to blow due to a typhoon or the like, it is not possible to avoid damage such as falling fruit unless the deployment work of the net is quickly completed. In some cases, it may be necessary to climb to the top of unstable pillars and carry out severe deployment work that is aware of the dangers. Windproof after installation Also in the management plane of the net, it has become a situation that faced an extremely difficult problem.

[0005] To address these many problems,
Some proposals have also been made for improved windbreak nets that allow the windbreak net to be opened and closed on the ground without climbing high altitudes, or the apple cultivation farmers have implemented their own ideas. Some of the proposed methods have been proposed, and the means of opening and closing the windbreak net at facilities that have been proposed and implemented by individuals have to use long rods that reach as high as possible. It is an extremely difficult task for weak elderly people, women and women, etc., because it is an operation method that directly pushes and pulls high places on the windshield net using it, especially while continuing an upward unreasonable posture, The work of walking and moving across the opening and closing width of the net was not only fatigue but also sometimes dangerous.

[0006] In other words, in the case of this kind of windbreak facility, which is often installed at the border of an apple field, when the installation location is a place where maintenance is not usually accessible or the entire field is a slope. It is a troublesome task that always involves the danger of falling down by stuck on stumps, tall weeds, bushes, etc., resulting in serious injury, and the scaffold remains unstable in this way Because it is an unfamiliar task to operate a long rod from the usual, it is not necessary for elderly people and women and girls who are weak in power, but also for workers with strong working primes They had to deal with a considerable burden that they rarely experienced, and they had to worry that even ordinary farming would be hindered.

[0007] In view of the above-mentioned conventional work of opening and closing the windbreak net, the inventor of the present application has made it possible to operate even if the worker is a provisionally incapable elderly person or woman. I realized the necessity of putting a windbreak facility into practical use so that it can open and close the windscreen safely and quickly without requiring any special strong force and taking an unreasonable posture. As a person who has been requested to install traditional facilities from before, we started development and research quickly, repeated many trials and experiments along with trial and error over a long period of time, and as a result, this time it is finally very useful as described later A new method of opening and closing the unit windbreak net of the windbreak facility and a windbreak facility with a new structure for implementing the method have been completed and put into practical use. In the following, details of the configuration will be described together with an embodiment representing the present invention shown in the drawings.

[0008]

As clearly understood from the representative embodiments shown in the drawings, the method for opening and closing a unit windbreak net of a windbreak facility included in the present invention basically has the following structure. It is a gist. That is, a unit wind avoidance net formed with a predetermined height and width and integrated with an opening / closing guide rod at one of the right and left edges of the four peripheral edges is provided for a pillar that is erected at predetermined intervals. It is suspended and oscillated freely on one side of a plurality of reinforcing wires stretched between the pipes, and the other end of the unit wind net is temporarily attached to the corresponding support pipe. In the windbreak facility, each of the unit windbreak nets has one end edge on which the opening and closing guide rod is integrated, and the towed ropes are separately extended right and left with the opening and closing guide rod as a starting end, Further, only by pulling down the towing rope on either side which has reached the lower part of the support pipe via the direction changing roller or pulley arranged at a predetermined position on the support pipe located on the extended side. A unit that can be opened and closed and that is open or closed to a predetermined position By keeping the avoiding net as it is in this state, the left and right towed ropes are tensioned together and temporarily fixed to the appropriate place below the corresponding support tube by winding or other means to obtain the desired opening degree. This is a method of opening and closing a unit of a windbreak facility at a windbreak facility, wherein the windbreak net is held.

[0009]

[Related invention 1] In connection with the method for opening and closing the unit windbreak net of the above-mentioned windbreak facility of the present invention, the windbreak facility having the following structure is also required to effectively implement the opening and closing method. It is included in the present invention as a wind shield facility. That is, a unit wind-prevention net formed to have a predetermined height and width, and an opening and closing guide rod is integrated on one of the right and left edges of the four peripheral edges, and a base end side for burying in the ground. A predetermined number of wire extension metal fittings are formed above the buried support portion, and the reinforcement wire is inserted through a reinforcing wire that is attached to one side of the unit wind net at predetermined vertical intervals. , And a support tube formed in the same direction as the pillar, and the buried support portion is buried in the ground at a predetermined position, and is erected at a predetermined interval substantially corresponding to the lateral width of the unit wind net. While reinforcing wires are stretched between the wire-stretching brackets at the corresponding height positions of the supporting pipe body, two reinforcing wires of these reinforcing wires are connected to the unit windbreak net. On the corresponding part of the opening and closing guide rod integrated with one edge The guide pulley that has been pulled off is immovable and inserted in a suspended state, and from around the middle of the pair of upper and lower guide pulleys, the towed ropes are separately extended to the left and right with the opening and closing guide rod as a starting end, and further extended. The column for the post located on the side where it has reached the lower portion of the column for the column via a turning roller or pulley arranged at a predetermined position, and all other or limited reinforcing wires have a unit. This is a windbreak facility that has a configuration in which slide rings arranged at key points in the windbreak net-compatible area are inserted.

The unit wind net is a machine-knitted 3 to 10 mm like various known synthetic resin nets for enclosures which have been conventionally used in agricultural work and construction sites.
It is a synthetic resin net with a single-layer or laminated structure of the front and rear meshes, the height according to the height of the fruit tree to be protected, the strength of the support tube and the reinforcing wire that is stretched between them Width determined by strength and number, for example,
For apples and peaches, the height (3-7) m x the width (5-1)
0) It is cut to a size of about m and its four peripheral edges are appropriately reinforced by reinforcing bands, and reinforcing cords are woven or sewn over the entire width at predetermined intervals in the vertical direction. Is adopted. In addition, this unit windshield net is formed mainly to fulfill the windshield function.In some cases, the unit windshield net is also used for a snow protection net provided along the road side to prevent snow accumulation on the road. It may be formed as one that can be diverted.

[0011] The unit wind shield net includes at the most important places including the uppermost and lowermost parts corresponding to a plurality of upper and lower (usually four or more) reinforcing wires which are stretched between the support pipes. Slide rings such as stainless steel or synthetic resin S-rings were attached, and by fitting these slide rings to the corresponding reinforcing wires, the unit wind net was supported by the reinforcing wires. A tension structure is realized so that the reinforcement wire can be spread or folded as a guide. However, in some cases, the sliding ring to be attached corresponding to two of the reinforcing wires stretched at positions other than the uppermost and lowermost positions may be replaced with the sliding ring, and may be opened and closed as described later. By adopting the same guide pulley as the guide pulley to be attached to the guide rod, it is possible to make opening and closing and sliding to the left and right smoother.

The opening / closing guide rod is integrated along the outer side of the edge reinforced by a reinforcing band at one of the left and right ends of the unit wind net (that is, the side on which the opening / closing operation is performed), and vertically.
When the edge is pulled or pushed along with the reinforcing wire, the edge functions so as to be able to perform an operation in which the edge is maintained in a state where it is held in a substantially straight line up and down. Along with being formed from a lightweight and strong material such as a square steel pipe or a PVC pipe, it is preferable that flange pieces directed in the same direction are continuously formed on the same straight line on the side or at appropriate intervals in the vertical direction. In addition to the fact that the flange piece is formed as a dedicated member that is to be a connection portion to the leading edge, an existing mold steel or PVC pipe or the like having an optimal size is selected and adopted, It is also possible to attach a separate connecting band to a key point in the direction, and attach the unit to the edge of the unit wind net by using the connecting band so that the unit can be integrated.

Further, in the opening / closing guide rod, guide pulleys are provided at positions corresponding to the two reinforcing wires of the reinforcing wires except for the uppermost and lowermost positions in the middle thereof. These guide pulleys are designed to be non-droppingly and hangingly combined with the reinforcing wire, and one end of each of the open / close guide rods located between the places where these guide pulleys are attached is provided. The other end of each of the left and right separate tow ropes, the sides of which are attached to the opening and closing guide rod, are extended substantially horizontally in a direction along the reinforcing wire, and the column tubes for the struts located on the extending sides, respectively. It is guided under the column for a support through a direction changing roller or a pulley provided in advance at a corresponding location so that the column becomes a drooping shape. Use the wound part in advance within the reach of As what was done, each hanging end side was wrapped around these winding parts, and after keeping it organized, the edge of the unit wind avoiding net on the side where the opening and closing guide rod was attached, When trying to move in either direction, the towing ropes arranged in that direction,
By pulling the hanging end downward, the unit wind net can be opened and closed smoothly.

The towed rope may be formed of a durable and flexible string, for example, a hemp string or a nylon rope. It is not necessarily supported between the roller and the pulley, and there is no danger that it will hang down.However, after the opening and closing operation is completed, both the hanging end portions are pulled, and then the above-mentioned winding portion is pulled. If it is wrapped around, it is possible to maintain a sufficiently tense state, and it is not necessary to suspend a special support fitting or the like from a reinforcing wire or a windbreak net, and to support a midway. In addition, the lowering operation of the hanging end portion is performed by an automatic winding mechanism that allows the winding motor to be automatically wound by a driving motor, that is, by connecting both the hanging end portions to an endless towed rope. Around the drive motor, the drive motor forward rotation,
It is also possible to adopt a structure in which the unit wind avoiding net can be opened and closed by mechanical means by performing the reverse operation.

[0015] The pillar tube has a very important function to spread and support the unit wind net, to which a considerable external force is applied in response to a strong wind, in a substantially vertical shape at a predetermined location of the orchard where the wind blows. The base end side of the member must be formed in a buried support portion that is sufficiently embedded and fixed in the ground so that the member is erected on the predetermined ground with sufficient strength. From the viewpoint of handling and embedding the member, the buried support portion is formed separately from the column body projecting upward, and the lower portion of the column body is inserted or inserted into the buried support portion. The buried support section should have a structure that allows it to be used as a support tube. Fins with fins extending radially on the side It should be embedded supporting section come.

The buried support portion has a structure in which it is driven into a predetermined ground by a driving machine as appropriate, and is directly supported on the ground. After laying the ground and preparing the groundwork, while holding this buried support vertically, concrete is poured around it, cured, solidified and supported on the ground via a strong foundation It is also possible to adopt such a configuration. Even in the case where the buried support portion is a pillar tube integrally formed below the pillar body, the support and integration of the buried support portion on the ground are the same as those of the divided and formed structure described above. To be implanted and fixed. However, in the case of embedding and fixing one pipe for a pillar and using a concrete foundation structure, it is necessary to take measures to reinforce with a temporary support frame until the concrete is cured and solidified. is there.

A plurality of wires extending in the same direction are arranged on the same straight side surface of the pillar tube thus standing, at intervals corresponding to the reinforcing wire stretching intervals. The metal fittings are projected and formed, and between the wire strut metal fittings at the same height position between adjacent support pipes,
The reinforcing wire to be described later is in a penetrating shape or a latching shape, and is designed to be passed over in a sufficiently tensioned state. As the wire tensioning fitting portion, the reinforcing wire is continuously connected to a plurality of support pipes. A structure that can be smoothly moved in the axial direction, for example, a ring-shaped suspension ring or a small-diameter short steel pipe, is protruded by welding or other means so that it can be stretched to be in a tensioned state. It is formed into a structure, it is a structure with a through hole formed by penetrating the pillar tube horizontally, or it is fixed so that a tension state is realized only between adjacent pillar tubes. It is possible to employ a latch fitting having means.

The reinforcing wire is stretched in a substantially horizontal manner through a wire extending fitting portion provided in advance in a column for a pillar which is erected at intervals corresponding to the unit wind width in the above structure. In addition to the function of suspending and supporting the unit wind avoidance net described above, it functions as a guide track when opening and closing the unit wind avoidance net in the left and right direction, and is a sufficiently strong material. For example, a metal rope such as a stainless steel wire rope or a nylon rope should be used, and the stand-up tube interval, the weight of the unit wind net to be supported, and the expected wind pressure, etc. It must be formed to have a sufficient cross-sectional dimension that is considered comprehensively.

The temporary fixing member is integrated with one side edge which is an opening / closing operation side of the unit wind net when the unit wind net is completely spread between the column tubes. The opening / closing guide rod is temporarily attached to the side of the support pipe that is drawn into contact with it, and the expanded unit wind avoiding net is fluttered by strong wind and fluttered or pulled back to avoid wind. A temporary attachment structure that can temporarily fix the open / close guide bar, such as a stop pin that holds the cross section of the open / close guide bar and prevents it from coming out. By combining such a structure as represented by an embodiment to be described later, or by winding a belt to stop, or by rotating a vise lever. 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,
The fittings attached to the support pipes are fitted to them, dropped, engaged, and combined by other general temporary attachment means. As described above, the support tube can be attached to a predetermined portion of the support tube with a separate band, or can be integrally formed at a predetermined position below the support tube with a firm fixing means such as welding. Shall be. In addition, this temporary fixing metal part makes it possible to temporarily attach two places in the middle of the opening and closing guide rod, thereby ensuring a temporary attachment state in which it is attached to the side of the column for the column of the opening and closing guide rod. be able to.

On the other hand, one end side of the reinforcing wire to be stretched between the support pipes is strongly placed at a height position within the support pipe below the necessary support pipe and accessible to the operator. A wire that can be pulled and fixed between tension pipes while keeping the reinforcement wire in a tensioned state, and can also be used for rewinding to adjust the looseness of the reinforcement wire appropriately after tension adjustment. It would be very convenient if the extension device was to be incorporated.

This wire stretching device is of a roller winding type as typified by an embodiment to be described later, and a predetermined weight is hung at the end of each reinforcing wire. By always pulling the reinforcement wire downwards to keep the tension state, or connecting the end of the reinforcement wire to the retracting lever and the end of the bolt, and advance and retreat the screw of the bolt to the nut A reciprocating adjustment mechanism for moving the reinforcing wire forward and backward, and further comprising a notch feeding mechanism that is provided with engaging means in only one direction such as a hook wheel in a winding portion and is rotatable only in the winding direction. For example, a known winding structure may be appropriately incorporated. In the following, the most typical embodiment will be disclosed and added with a specific description so that the configuration included in the windbreak facility of the present invention described so far can be more clearly understood. I do.
