Description

Detailed Description of the Invention

[0001]

An object of the present invention is to cover fruit trees such as fruits such as cherries and limes for preventing harmful effects such as cracks and lesions caused by exposure to rainwater and deteriorating commercial value. It is related to tools, and it does not require large-scale work like the conventional fixed stationary pipe frame covered with a vinyl sheet in advance, and can realize quick and simple fruit tree covering for every desired one or several fruit trees. The present invention intends to provide a fruit tree covering device having a novel structure that can be diverted to other coverings as needed.

2. Description of the Related Art When exposed to rain, seedlings in the cultivated plant season may die, or cherries, lemons, limes, and other fruits that are about to reach the harvest season may have cracks or lesions. In order to prevent such harmful effects, a pre-framed pipe frame is covered with a vinyl sheet to create a waterproof roof, which protects trunks, foliage, and near-harvest fruits from rainwater, and roots. Although fruit tree covering work such as ensuring the dry condition of the part and surrounding soil has been done, such conventional vinyl sheet erection work is extremely large-scale work, and it is completely performed for old people and women. It was impossible to do so, and I had no choice but to borrow a man from a neighbor or ask a specialist to spend a large amount of money. Moreover,
The covering facility that was set up in this way refused to spray chemicals afterwards and introduced various agricultural machinery into the field,
It also hindered the series of farm work required before fruit harvesting, and had another problem of hindering efficient farm work.

Regarding cherries, which are a specialty of Yamagata Prefecture and are known as a representative of adorable fruits nationwide, they prefer a relatively cool and dry climate, and the growth of fruit trees throughout the year is accompanied by it. Cultivation management must first be carried out from January to early March by pruning and pruning to adjust the tree shape and improve the fruiting, and then to spray pesticides to prevent pests. And, as for this cherry, not only the fruit but also the brown scab which affects the flower and the young leaf and the fruit fly which damages the fruit are the big enemy, the lime sulfur mixture 10-20 times before germination for the brown star disease. Spray the liquid,
In addition, Lobrar wettable powder 1 at intervals of 10 to 14 days after flowering
Disperse 0 to 20 times the amount of liquid, and at the same time, salition emulsion 1000
It is also necessary to mix insecticides such as double the liquid, and artificial flowering is performed after flowering from the end of March to the beginning of April, and fruit is harvested in early May leaving good fruit. It takes a lot of time, and finally the harvest is done from late June to the end of July.

Since the harvest season just coincides with the rainy season, the fruit trees are more often exposed to rain than in other seasons, and the elastic fruits of cherries before harvest are exposed to rainwater when they are exposed to the epidermis. It absorbs water and breaks into pieces, resulting in loss of fruit not only in beauty but also in commercial value. In order to maintain the commercial value of cherries, cherries cultivating farmers, who must do so, must be aware of the inefficiencies of some farming work and rely on the above-mentioned fixed pipe frame fixed fixtures. It's a reality.

Lemons and limes cultivated south of the Kanto region are pruned from February to March, bloom from April to May, and reach the harvest season from November to December. There is a need for spraying chemicals such as insecticides and bactericides from January to September, and frequent need for cold fertilizer and additional fertilizer, which requires a great deal of labor for daily management regarding cultivation. Especially,
In summer, canker disease and black spot disease may occur, and it is necessary to promptly remove the fruit with disease spots and burn it. In these diseases, spores of pathogenic bacteria floating in the air attach to leaves and fruits, rainwater hits them and germinates, and the germinated pathogens invade from the pores on the surface of leaves and fruits and propagate to the plants. Since the fruit absorbs nourishment from the plant, the growth of the fruit does not deteriorate, and the fruit loses its commercial value.In order to avoid the adverse effects of rainfall, these fruit trees also have a vinyl pipe mounted on the fixed pipe frame as described above. Roofing with a covering sheet made of a sheet or the like has been widely performed.

[0006] The simplest way to hang a roof on such a fruit tree is as shown in the perspective view of FIG. 8 showing the roof hung on the conventional vinyl sheet. 32, 32, ..., etc. are tied up so as to hold the fruit tree 33 at a height to cover it from above to prepare for rain, and although not shown,
The large-scale is to collect 5 to 10 or more fruit trees lined up at a predetermined interval, and a gate-type pipe frame of 60 to 100 so that it becomes one temporary structure.
A number of cm intervals were erected and combined to form a skeleton so that these fruit trees could be straddled, and the skeleton made higher than the fruit trees was used as a support, and a long, wide covering sheet was covered. , The cover sheet is appropriately tensioned with a press band, and in the case of cherry fruit trees,
By covering the fruit with a vinyl sheet 31 at the beginning of coloring, fruit cracking can be prevented, and with lemon and lime, by hanging the vinyl sheet 31 when the fruit is attached, germination of pathogenic bacteria due to rain can be prevented. However, the covering facility of the type in which the skeleton body is covered with the vinyl sheet 31 that has been once constructed is an obstacle to repeated spraying of various chemicals, additional fertilizing work, fruit harvesting, etc. Even when moving a large agricultural machine in an orchard field, the poles such as the bamboo rods 32, 32, ..., and the pipe frame became an obstacle, and it was not possible to streamline the agricultural work as desired.

The inventor of the present application can very easily fold the roofing by the covering sheet of the vinyl sheet, which is indispensable for the fruit trees that are about to be harvested soon, at the time of spraying the chemicals and the harvesting work. If it is possible, and when it is likely that it will rain, we have begun to realize a new covering tool that makes it possible to put the covering sheet on the fruit tree quickly and easily, and for a long period of time. As a result of repeating trial manufacture and examination, it was finally succeeded in completing a fruit tree covering that is worthy of practical use. In the following, the configuration will be described in detail together with an example representing the present invention shown in the drawings. And

[0008]

As clearly understood from the embodiments of the present invention shown in the drawings, the fruit tree covering of the present invention basically has the following structure. That is, the base ring is attached to the upper end or the upper end side of the pillar standing on the ground or movably up and down, and a plurality of folding skeleton bases are arranged radially around the ring. , Both base ends of which are pivotally attached to each other are pivotally movable from a state in which they are substantially horizontal to a state in which they are downward or upward to shift to a state in which they are almost vertical, and the rotation of each is mutually In addition to making it possible to connect in a structure that motion is linked,
The free ends of the folding skeleton bases extend radially from the support pillar or the force bone body ring body fitted to the support pillar, and the base end is extended to the support pillar or the force bone body ring body fitted to the support pillar. All the skeletons are connected to the midpoints of the skeletons that are rotatably pivoted in the up-and-down direction, and the skeleton bases are interlocked with each other, so that all of the skeletons move toward their free ends. It is a fruit cover that is made to be able to rotate by forcibly constricting it to the upper side, and a covering sheet is stretched over those skeletons.

If the fruit tree covering shown in these basic structures is shown as a more specific structure, the ring for the base is attached to the tip of the pillar standing on the ground while the base for the base is attached. A plurality of folding skeleton bases are arranged in a radial pattern around the ring body, and both base ends of the fold skeleton bases are pivotally attached to each other so that the bases rotate from a substantially horizontal state to a substantially vertical state by rotating downward. The skeletal structure is freely rotatable and is connected so that the rotations are interlocked with each other, and the free ends of the folding skeleton bases are connected to the support columns below the base ring. All the force bones are rotatably connected to the midpoints of the force bones that extend radially from the fitted force bone ring body, and all the force bones are rotated by the interlocking downward rotation of the folding skeleton bases. ,
Each free end side is forcibly constricted to the upper side so that it can be rotated, and a cover sheet is stretched over those skeletons, and a fruit tree covering and standing on the ground A base ring is vertically movably fitted on the upper end side of the column, and a plurality of folding skeleton bases are radially arranged around the base ring, and both base ends are pivotally attached to each other. It is free to rotate from a state of being substantially horizontal to a state of being moved upward to a state of being substantially vertical. The free ends of the folding skeleton bases are respectively rotatable in the midpoints of the force bones that extend radially from the force bone ring attached to the support column located a predetermined distance below the base ring. All of the skeletons are connected to the folding skeleton base body by the interlocking rotation of the folding skeleton base body to the upper side. Free end forcibly without those capable of pivoting to become deflated upward side, a cover as the the fruit covering device comprising stretched sheets to their power bone bodies.

The column has at least a length equal to or greater than the height of the target fruit tree, and moreover, it is possible to mainly support a folding skeleton base body, a skeleton body described later, a covering sheet to be covered thereon, and the like. It must be structurally strong enough to withstand wind pressure applied to them, and it must be as light as possible in handling and handling. A thin tube made of stainless steel, or a thin tube in which these materials are combined is most suitable, and further, it is not just a single tube, but a known structure for increasing durability, for example, one having a plurality of ribs integrally formed on the surface, It is possible to form a reinforcing flange integrally or separately in the hollow part, to form another composite structure, or to make a thin tube whose overall length is not the same diameter but whose cross section is narrowed toward the upper end side. Or adopt a cross-section other than the tube, if necessary in it like is of course possible to those of the structure of the shirttail formula.

The folding skeleton base body has both base ends of a U-shaped bent steel rod either directly attached to the above-mentioned support pillar or pivotally attached to a base body ring attached or fitted to the support pillar, and both bases A structure in which one base end side of the end portion is superposed on the other base end side of the other adjacent folding skeleton base body, and they are sequentially combined in one direction and arranged, and any one of them has a rotating action. Then, all of the folded skeleton bases must be formed in a structure in which the desired chained opening / closing action is forcibly obtained by interlocking with their movements. Therefore, the essential structure is , The adjacent folded skeleton bases are regularly arranged along the circumferential direction of the ring body for bases in a state in which some of the adjacent folded skeleton bases are sequentially overlapped, and when one folded skeleton base is rotated, the adjacent folded skeleton bases Substrates are forced to turn sequentially in a chain Other structures that have been manipulated to force all of the folded skeleton substrates to rotate at one time, ie, the folded skeleton substrates, are not limited to the U-shaped curved bar described above, It goes without saying that, for example, a combination of rigid plate materials in a petal shape is included.

The folding skeleton base body is rotated upward or downward from a state of being substantially horizontal to a state of being substantially vertical, and by its operation, the force bone body, which will be described later, is forced upward. In the case of rotating from an almost horizontal state to an almost vertical state by moving it from an almost horizontal state to a nearly vertical state, the base end of the folding skeleton base is Must be formed so that it can rotate while moving from the upper end to a predetermined range (the length of the substantially folded skeleton base, that is, the range corresponding to the length between both base ends and the free end). In addition, in the case of rotating from a substantially horizontal state to a substantially vertical state by rotating it downward, the base end of the folding skeleton base is attached to the upper end of the column. Formed as a structure that can be rotated It will be.

The strength bone body is supported at its base end directly on the pillar or via the strength bone ring, and a plurality of radial bone bodies are extended radially from the pillar to provide a predetermined area around the pillar (ie, a target area). The cover sheet that covers the area where you want to shield rainwater from the fruit tree that will become the supporting element is a component part that functions so as to be able to stretch these as a support part, so to speak, the function corresponding to the ribs of the bat umbrella, and therefore the cover. In addition to requiring structural strength (such as light weight and appropriate rigidity and durability) capable of additionally supporting the seat on the upper surface side or the lower surface side, seat attachment means, such as hooking, stringing, and clip fastening, are known. The stopper metal fittings and stoppers are attached to the required places so that they can be combined and installed, or it is made up of a force bone body in which a thin groove is engraved in the axial direction on the side of the cover sheet attachment,
After attaching the cover sheet, the cover sheet is attached to the periphery of the force bone by attaching means that presses the presser bar from above the cover sheet and pushes the cover sheet together with the cover sheet portion. It is necessary that appropriate publicly known attachment means such as an attachment means that also uses a C-shaped elastic sheath body that is pressed and fixed in a fixed shape is used.

The force skeletons are pivoted one by one or two or three at the free ends of the above-mentioned folded skeleton base so that the middle of the proximal end side thereof is pivoted. By the interlocked forced rotation of, the whole is collectively rotated upward with the respective base end portions as rotation fulcrums, and the respective free end portions operate so as to be narrowed upward (hence,
The cover sheet attached to it is also forcibly constricted to the upper side of the column. A) formed as. The upward rotation of these force bones is realized by manually rotating the folding skeleton base directly up or down, or alternatively, a wire rope or the like bound to one folding skeleton base. Alternatively, an opening / closing operation can be realized by appropriately adopting a power source such as providing a dedicated winding handle or winding and releasing by a drive motor.
It is only necessary to appropriately select and employ the most advantageous rotary operation means in terms of economy and workability.

In addition, all of these force bone bodies or necessary ones are provided with holes at appropriate positions near the free ends,
With or without a ring or hook attached, use them to connect and fix all free ends or essential points of the skeleton body in the expanded state via a cord or thin rod. By adjusting the length of the tension rope or the thin rod by incorporating a length adjusting structure such as a turnbuckle, the free end side of the power bone body is adjusted to the outer ground side. It is curved toward the side and its curved state can be adjusted to facilitate drainage of rainwater that falls on the cover sheet and prevent wind and rain from blowing from the side of the fruit tree. When it is necessary to deal with storms that are blown from one side, the curvature of the force bones is set to the maximum by adjusting the tension rope or thin rod short, and the invasion of raindrops and strong wind from the side is prevented as much as possible. Try to protect fruit trees, while light rain The length of the rope or thin rod should be adjusted to fulfill the function of supporting the strength of the stanchion, that is, left and right, back and forth, and only the upper side of the fruit tree is covered. Can be opened to promote the passage of wind from the side, prevent the ground from becoming over-humidified, and maintain a favorable growth environment as much as possible.

The force bone body attached to the cover sheet is provided with an appropriate temporary fixing mechanism for keeping its posture as stable as possible only in the closed state or in both the expanded state and the closed state. It is desirable that That is, it is of course possible to bind the closed state (the state in which the skeleton is squeezed upward) with a tie string or the like, and temporarily fix each time, but in the case of a large size, it can be done by one person. It is almost a difficult task to carry out, and for them, at least, for example, by inserting the temporary fixing ring into the column part slightly below the proximal end part (pivotally connecting part to the column) of the force bone body. Then, a simple temporary fixing mechanism should be adopted in which the entire operating force body including the covering sheet can be temporarily fixed in a lump by pushing up the operating rod extending below the temporary fixing ring.

More preferably, a temporary fixing mechanism capable of controlling the rotation of the folding skeleton base portion, for example, a lock mechanism capable of blocking and releasing the rotation of the rotation shaft of the pivot portion is incorporated in the force bone ring body. Therefore, a mechanism that enables unlocking operation with a wire from below the strut, or a stopper corresponding to the above-mentioned temporary locking ring can be operated from below the strut so that it can be fitted into and removed from the outside of the folding skeleton base portion. In addition, a mechanism is provided in which stoppers can be moved in and out of a supporting column so that one or a required portion of the folding skeleton base base end portion can be operated, and the stoppers can be operated below the supporting column. Various temporary fixings, such as a mechanism in which a mechanism like the above is incorporated between the force bone body and a support or a force bone body ring inserted into the support or a mechanism in which these are appropriately combined. If it is assumed that the structure has been incorporated a convenient thing.

In the opening / closing operation of the folding skeleton base body and the force bone body, a direct manual vertical movement operation can be transmitted to a required portion through an appropriate operating rod such as a pipe or a thin rod. A drive mechanism such as an AND pinion is provided, and it is assumed that the opening and closing operation is performed by indirect driving operation by a human operation, and a drive source such as an electric motor is installed in order to further save the opening and closing work. It is also possible to provide a structure that can be opened and closed automatically by operating the switch, and furthermore, the operation switch of the drive source for opening and closing a plurality of fruit tree coverings is unified.
A system that can automatically control the opening and closing operation of all or part of the fruit coverings provided in the entire field, for example, the movement of the switch is linked to the rain detection device that detects raindrops. Then, when it starts to rain, the fruit tree covering will automatically expand, and the weather will recover and it will be sunny,
When the raindrops are no longer detected, it is possible to perform an automatic opening / closing operation such as automatically driving the fruit tree covering device to the folded state.

As long as the covering sheet is intended for fruit tree coverings, the covering sheet is translucent and can absorb light even in rainy weather to promote the growth of fruit trees, such as vinyl sheet and polyethylene sheet. Such as plastic sheets or films already used as covering sheets for fruit trees, or various transparent sheets or films that will be developed in the future and have excellent light transmission and durability, and cover for other purposes. When it is used as a tool, for example, when it is used as a light-shielding cover, a warming cover, a frost damage-preventing cover, a storm cover, etc., a sheet or film, a net, etc. of the optimum material changed to those will naturally Needless to say, it is desirable that all of them be as light as possible and have excellent durability and weather resistance.

Since this cover sheet is formed as a structure that can be folded compactly at any time, even if it is a cover sheet used exclusively as a covering for fruit trees, it does not have a light-shielding property or a light-reflecting property. It is also possible to use a sheet equipped with it, and when it is sunny, it is folded to secure the light to the fruit tree, and when it is raining, it opens to block the rainwater and protects the fruit tree from strong sunlight and strong dryness. Even when it is necessary, it can be opened and used also as a light-shielding cover, and it can be realized as a fruit tree protection device having multiple functions. In addition, the cover sheet is not limited to a single layer, but the sheets with different properties may be stacked, and the breathability and the lighting condition may be appropriately changed by cutting the whole sheet or a part thereof according to the purpose, or Various applications and modifications are possible, such as improving the strength of the cover sheet. Hereinafter, some embodiments shown in the drawings will be described in detail so that the constitution of the fruit tree covering device included in the present invention can be grasped more specifically and clearly.

It is also a versatile facility that can be easily used as a temporary resting facility for tourists, such as a cover facility for mochi or a mochi orchard.

Furthermore, since it can be folded and opened / closed, it is easy to take measures against storms, and unlike the previous ones, even during a storm, it cannot be removed easily before it, and it is unavoidably stormy. The risk that it will be exposed and seriously damage the facility itself will be extremely reduced, and it will be possible to use it for many years with a relatively simple structure,
The extremely compact whole can be repeatedly used as a rod-shaped material for handling such as storage and loading.
The tip of the force bone can be fixed easily and optimally with a tension rope, and the structural strength of the covering itself can be easily secured, so it has excellent durability in normal conditions and measures against rainwater blowing. It is also advantageous that measures for avoiding loads due to water pools become extremely easy, and its economic effect is
It is incomparable to the previous ones.

Pivotally mounted around the ring body 7 is arranged in a state of overlapping each other, and one folding skeleton base 8 is formed. All other folding skeleton bases 8, 8 ... Have the most practical structure that enables chained and automatic rotation by rotating the. It can be demonstrated evenly, and
The fruit tree covering 21 of the second embodiment includes the skeletons 26, 26, ...
It consists of a typical configuration that excels in opening and closing operation, in which the sliding ring 25 for opening and closing can be operated by the operating rod 27 that extends along the support column 22, and for fruit tree farmers expecting labor saving. It is expected that it will make a great contribution to this.

As described above, the fruit tree covering of the present invention is structurally relatively simple and easy to manufacture, mainly as a covering required for avoiding rainwater on fruit trees,
In addition to making it possible to provide it at low cost, it is extremely easy to handle such as carrying in as a material, storage, operability as a covering tool, etc., and quick operability according to the fruit cultivation process is guaranteed. Therefore, it is possible to contribute to labor saving of fruit tree farmers, enable highly productive farm management, and be one effective measure against severe price competition with fruit products imported from overseas. It is expected to be.
