Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a simple plant cultivation facility used for greenhouse cultivation and tunnel cultivation of plants, and a cover sheet used therefor.

[0002]

2. Description of the Related Art Generally, vegetables such as vegetables, fruits, or flowers are cultivated in greenhouses in cold climates. In greenhouses, glass chambers are covered with glass, and polyvinyl chloride and polyethylene are used instead of glass. A vinyl house using a plastic film such as is well known.

On the other hand, a simple plant cultivation facility called a frame (hotbed) or a tunnel (floating mulch) is well known as an inexpensive structure that can replace such a relatively large greenhouse. Explaining the form by referring to FIG. 12, R is an arch-shaped rib (support) made of plastic or the like, and they are arranged in the ridge U at appropriate intervals to form a tunnel-like semi-cylindrical shape. Form the framework F.
Further, S is a cover sheet stretched on the outside of the frame F, and for this, a plastic film such as polyvinyl chloride or polyethylene, or a porous cloth (net) such as a gauze cloth is used.

According to the plant cultivation equipment of that type,
Protects plants from wind and rain, and also dry and chill damage to the cultivated soil,
It is possible to prevent insect damage and to grow the plant well under suitable conditions.

[0005]

However, it is very difficult to construct and dismantle the conventional equipment as described above. Especially, the work of fixing the cover sheet to the frame is not easy,
In vinyl greenhouses, clips with a C-shaped cross section are attached to the framework one by one from the top of the cover sheet, and rubber cords are stretched around the cover sheet. On the other hand, in frames and tunnels, wire or wire is placed on the cover sheet that covers the framework. Since a wire material such as a resin string is stretched, there is a problem that a lot of time and labor is spent on this.

Further, in the case where the cover sheet is fixed with a clip, it is difficult to remove the clip from the frame at the time of disassembly, and the cover sheet may be damaged at the time of removal.

Further, in the case of pressing the cover sheet from above with a wire material such as wire, improper fixation of the cover sheet causes the cover sheet to be rolled up by being blown by the wind, and in some cases, it is blown off. It was sometimes lost.

The present invention has been made in view of the above circumstances, and an object thereof is to enable a cover sheet for covering a plant to be easily and satisfactorily fixed to a framework, thereby reducing labor required for this. And to reduce the work time.

[0009]

In order to achieve the above object, the present invention comprises a framework composed of a plurality of ribs for forming a plant cultivation space, and a cover sheet stretched over the framework. In the plant cultivation equipment described above, the cover sheet is integrally provided with a locking means capable of being fixed to each rib constituting the framework.

Further, in the above-mentioned cultivation equipment, the locking means is provided with a plurality of rows of sleeves or loop groups extending along the width direction of the cover sheet so as to individually pass the respective ribs, or two ribs wound around the outer circumference of each rib. It is characterized in that it is composed of a set of string-like bodies.

Further, the cover sheet is characterized by being made of a transparent plastic film or a breathable porous cloth.

On the other hand, in a cover sheet stretched over a frame composed of a plurality of ribs so as to cover a plant, locking means for fixing the ribs constituting the frame to the ribs is provided at that portion. The stop means comprises a plurality of rows of sleeves extending along the width direction of the cover sheet so as to individually pass each rib.

Further, in the above-mentioned cover sheet, the sleeve has a total length shorter than the entire width of the cover sheet, and both ends thereof are opened at positions spaced inward from both side edges of the cover sheet.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, application examples of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a usage mode of a plant cultivation facility according to a preferred embodiment of the present invention.
In FIG. 1, 1 is an arch-shaped rib (support), which constitutes a frame 2 with a plurality of (about 10 to 30) as a set, and when used, along a ridge U as shown in the drawing. A semi-cylindrical plant cultivation space 3 is formed at a predetermined interval and has a tunnel shape inside thereof.

In this example, each rib 1 is a fixed shape made of hard plastic or metal, but it is a linear bar material having flexibility so that it can be curved in an arch shape at the time of use. You may

On the other hand, 4 is a cover sheet stretched outside the framework 2 so as to cover the plants. In this example, a transparent or semitransparent plastic film having a light transmitting property is used for the cover sheet 4. . As the transparent or translucent plastic film, thermoplastic resin such as soft polyvinyl chloride, low density polyethylene, polystyrene, polypropylene, polyacrylonitrile, polyester, or ethylene-vinyl acetate copolymer can be used. Vinyl and low density polyethylene are preferably used.

In order to adjust the amount of light entering the plant cultivation space 3, the cover sheet 4 may be impregnated with an inorganic pigment or other colorant, or several cover sheets 4 may be stuck together. Here, the cover sheet 4 is available in various sizes, but the total length is set to about 10 meters to several tens of meters and the total width is set to several meters.
At the time of use, the periphery is buried in the ground. In particular, the cover sheet 4 has locking means for fixing it to the frame 2,
An elongated tubular sleeve 5 is provided integrally to pass each rib 1 individually.

According to the plant cultivation equipment (tunnel) as described above, the plants planted in the ridges U are protected from wind and rain and harmful insects, and moreover, the inside is kept warm while preventing the soil from drying, and the plants are kept in good condition. Can be grown.

Next, FIG. 2 is a developed view in which the cover sheet is partially cut away, and FIG. 3 shows an XX line in FIG.
A line cross section is shown. As is clear from these figures, the sleeve 5 extends along the width direction of the cover sheet 4 (vertical direction in FIG. 2) and is spaced apart in the length direction of the cover sheet 4 (horizontal direction in FIG. 2). Multiple rows are provided in parallel. still,
In this example, the sleeve 5 is formed by using a belt-shaped member (ribbon-shaped plastic film) of the same type as that of the cover sheet 4 and heat-welding both side edges to the inner surface of the cover sheet 4. The welded portion is shown by a dotted line in FIG. 2. However, when the cover sheet 4 is made of a material having no thermoplasticity such as cloth, the sleeve 5 is a belt-shaped member made of cloth or the like, and both side edges thereof are covered by the cover sheet. 4 is formed by being attached to the inner surface of 4.

The sleeve 5 may be formed in a continuous manner over the entire width of the cover sheet 4, but it is preferable to make the entire length shorter than the entire width of the cover sheet 4 as shown in FIG. The structure is such that the sheet 4 is opened at a position separated from the both side edges 4A of the sheet 4.

Explaining the reason for this, FIG. 4 is a schematic front view showing a mode of use of the plant cultivation equipment, and FIG. 5 shows a partially enlarged cross section taken along line XX of FIG. As is apparent from these figures, the sleeve 5 forms a cylindrical hollow portion 6 between the cover sheet 4 and the rib 1 so that the rib 1 can pass therethrough. Then, the ribs 1 constituting the framework 2 are respectively passed through the sleeve 5, and both ends 1A thereof project from the both end opening portions 5A of the sleeve and are pierced into the ground on both sides of the ridge U. The opening 5A is located higher than the ground so that both ends 4B of the cover sheet can be rolled up to the position of the sleeve 5.

Here, both ends 4B of the cover sheet are normally hung so that their lower ends are buried in the ground to prevent cold air and harmful insects from entering the inside, and When it is rolled up as shown by the imaginary line 4, the outside air can be taken into the plant cultivation space 3 for ventilation.

According to the above plant cultivation equipment,
Sleeve 5 with which the cover sheet 4 is integrally formed
Is firmly fixed to the framework 2 by the cover sheet 4
Is not blown away by the wind, and when not in use, it is stored in a warehouse, etc. by folding it shortly with the cover sheet 4 attached to the framework 2 as shown in FIG. It can be easily installed just by.

Although the application example of the present invention has been described above, such a plant cultivation facility can be applied not only to a frame (tunnel) but also to a larger greenhouse. Here, the vinyl house does not mean that a vinyl film or sheet in a narrow sense is used as a cover sheet, but the vinyl is a general term for plastics obtained by polymerization or copolymerization of a compound having a vinyl group.

Further, as the cover sheet, not only a light-transmitting plastic film such as polyvinyl chloride or polyethylene is used, but also a breathable porous cloth (cloth) or non-woven cloth such as a gauze cloth is used. Good.

Further, in the above example, a long and thin cylindrical sleeve is formed on the cover sheet as the locking means for fixing the cover sheet to the frame. However, as the locking means, a loop group or a pair of two is formed on the cover sheet. A string-like body may be provided.

FIG. 7 shows an example in which a loop group that replaces the sleeve is provided on the cover sheet. Here, the loop groups 7A, 7
B, ... Are provided in parallel in the length direction of the cover sheet 4 (left and right direction in FIG. 7) at predetermined intervals, and
The loop groups 7A, 7B, ... In each row are formed by arranging a plurality of loops 7 in series in the width direction of the cover sheet 4 (vertical direction in FIG. 7) at predetermined intervals. In addition, each loop 7
As shown in FIG. 8, both ends of a strip-shaped member made of a plastic film or cloth are attached to the cover sheet 4 by welding or adhesion. Then, the loop groups 7A, 7 in each column
The ribs 1 are individually passed through B, ... As shown in FIGS.

On the other hand, FIG. 10 shows an example in which the loop is replaced by a pair of string-like bodies. Here, the cord-like bodies 8A and 8B are attached by welding or adhering one end thereof to the inner surface of the cover sheet 4, and are provided at positions corresponding to the ribs 1 along the longitudinal direction thereof at predetermined intervals. Then, the string-like bodies 8A and 8B are wound around the outer periphery of the rib 1 by being tied together as shown in FIG.

Even the cover sheet provided with the loop group or the cord-like body as described above can be firmly fixed to the frame so that the cover sheet is not blown off for use and the tensioning work can be performed indoors or the like. In use, the cover sheet can be easily installed at a desired place by expanding the fixed framework.

[0030]

As is apparent from the above description, according to the present invention, a sleeve, a group of loops for passing each rib of the frame through the cover sheet, or a pair of two cords wound around the outer periphery of each rib. Since the locking means such as the body is integrally provided, work to attach C-shaped clips one by one to the framework from the top of the cover sheet as in the past, or to put wire etc. Is unnecessary, and since the work of stretching the cover sheet can be done not only locally but also indoors in advance, workability is greatly improved, and the rib intervals are inevitably determined, so it is difficult to arrange them. Nothing.

In particular, since the sleeve as the locking means can be easily provided by welding a long belt-like member, it can be manufactured at a cost not much different from the conventional cover sheet.

Further, since the total length of the sleeve is shorter than the entire width of the cover sheet and both ends of the sleeve are opened at positions inwardly of both side edges of the cover sheet, both ends of the cover sheet are separated from the ribs. Both ends of the cover sheet can be easily rolled up when the plant cultivation space is ventilated by being spaced apart and buried in the ground.

A cover sheet for plant cultivation, which is characterized by being set.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, application examples of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a usage mode of a plant cultivation facility according to a preferred embodiment of the present invention.
In FIG. 1, 1 is an arch-shaped rib (support), which constitutes a frame 2 with a plurality of (about 10 to 30) as a set, and when used, along a ridge U as shown in the drawing. A semi-cylindrical plant cultivation space 3 is formed at a predetermined interval and has a tunnel shape inside thereof. In this example, each rib 1 is a fixed shape made of hard plastic or metal. On the other hand, 4 is a cover sheet stretched outside the framework 2 so as to cover the plants. In this example, a transparent or semitransparent plastic film having a light-transmitting property is used for the cover sheet 4. Examples of the transparent or translucent plastic film include soft polyvinyl chloride, low density polyethylene, polystyrene, polypropylene, polyacrylonitrile, polyester, or a thermoplastic resin such as ethylene-vinyl acetate copolymer.
In particular, soft polyvinyl chloride and low density polyethylene are preferably used. In order to adjust the amount of light entering the plant cultivation space 3, the cover sheet 4 may be impregnated with an inorganic pigment or other coloring agent, or several cover sheets 4 may be stuck together. Here, the cover sheet 4 is available in various sizes, but its overall length is set to about 10 meters to several tens of meters and its overall width is set to about several meters, and its peripheral edge is buried in the ground when used. Particularly, the cover sheet 4 is integrally provided with an elongated cylindrical sleeve 5 through which each rib 1 is individually passed, as a locking means for fixing the cover sheet 4 to the frame 2. And, according to the plant cultivation equipment (tunnel) as described above, the plant planted in the ridge U is protected from wind and rain and harmful insects, and moreover, the inside is kept warm while the soil is prevented from drying and the plant is favorably grown. be able to. Next, FIG. 2 is a developed view in which the cover sheet is partially broken, and FIG. 3 shows a cross section taken along line XX in FIG.
As is clear from these figures, the sleeve 5 extends along the width direction of the cover sheet 4 (vertical direction in FIG. 2) and is spaced apart in the length direction of the cover sheet 4 (horizontal direction in FIG. 2). Multiple rows are provided in parallel. In this example,
The sleeve 5 is formed by using a band-shaped member (ribbon-shaped plastic film) of the same type as that of the cover sheet 4 and thermally welding both side edges to the inner surface of the cover sheet 4. The welded portion is shown by a dotted line in FIG. 2. However, when the cover sheet 4 is made of a material having no thermoplasticity such as cloth, the sleeve 5 is a belt-shaped member made of cloth or the like, and both side edges thereof are covered by the cover sheet. 4 is formed by being attached to the inner surface of 4.
Also, the sleeve 5 is not formed in a continuous manner over the entire width of the cover sheet 4, but its entire length is made shorter than the entire width of the cover sheet 4 as shown in FIG. The structure is opened at a position separated from the inside of 4A. To explain the reason for this, FIG. 4 is a schematic front view showing a mode of use of the plant cultivating facility, and FIG. 5 shows a partially enlarged cross section taken along line XX of FIG. As is apparent from these figures, the sleeve 5 forms a cylindrical hollow portion 6 between the cover sheet 4 and the rib 1 so that the rib 1 can pass therethrough.

The application example of the present invention has been described above. However, such a plant cultivation facility can be applied not only to a frame (tunnel) but also to a larger greenhouse. Here, the vinyl house does not mean that a vinyl film or sheet in a narrow sense is used as a cover sheet, but the vinyl is a general term for plastics obtained by polymerization or copolymerization of a compound having a vinyl group. Further, as the cover sheet, not only a light-transmitting plastic film such as polyvinyl chloride or polyethylene may be used, but also a breathable porous cloth (cloth) or a non-woven fabric such as a gauze cloth may be used.

As is apparent from the above description, according to the present invention, the cover sheet is integrally provided with the sleeves for passing the ribs of the frame. It is not necessary to attach the cover sheets to the framework one by one, or to attach wires such as a presser on the cover sheet, and it is possible to perform the cover sheet tensioning work not only locally but also indoors in advance. Therefore, the workability is greatly improved, and the spacing between the ribs is inevitably determined, so there is no need to worry about the arrangement. In particular, since the sleeve as the locking means can be easily provided by welding a long strip-shaped member, the sleeve can be manufactured at a cost not much different from that of the conventional cover sheet. Further, since the total length of the sleeve is shorter than the entire width of the cover sheet and both ends of the sleeve are opened at positions separated from both side edges of the cover sheet, both end portions of the cover sheet are separated from the ribs.
