Description

The present invention relates to a sheet covering a cultivated land such as a paddy field and a covering material such as a net.

As a construction method for fixing using a tunnel insulation material, especially with a heat insulation (cold protection) sheet, conventionally, a zigzag is applied to the top of the covering material covered with a string-like object such as rubber or rope. The covering material was fixed with a strut so as to be sandwiched from above the tunnel covered with the covering material using a tunnel support.

When it is always sealed by the cultivation method using the tunnel covering material for heat insulation, the temperature in the tunnel rises too much and adversely affects the cultivated crops. Therefore, in order not to raise the temperature in the tunnel too much, the tunnel skirt must be turned up, ventilated, and temperature and humidity adjusted. Therefore, like the insect-proof tunnel, you cannot dig the soil in the valley and embed and fix the edge in the soil, and adjust the temperature and humidity, and use a string-like object or tunnel post so that it can be opened and closed It is fixed.

When fixing with a string-like rubber belt, etc., the covering material must be pressed and fixed with the belt so that the top of the tunnel-shaped covering material is zigzag left and right while the belt is hooked on the hooks at the valleys on both sides of the tunnel. In addition, it is not only difficult to fix alone, but because the covering material is pressed and fixed with a belt-like belt, the tunnel shape cannot be maintained or turned up unless the distance between the tunnel posts is narrow. It is necessary to install many tunnel struts at narrow intervals because the covering material cannot be fixed at the time.

The hook for hanging a rubber belt on the hook of the valley must be fixed by, for example, driving it into the ground, and it must be firmly installed so that it cannot be pulled out by the belt. In addition, these hooks, such as pegs, need to be installed on the left and right sides of the fence between each tunnel post, requiring approximately twice the number of tunnel posts and requiring a lot of materials and labor. To do.

In the case of fixing with a tunnel post, a tunnel post is straddled and covered with a covering material, and then another tunnel post from the top of the covering material is placed between the support post under the covering and the support post. Fix the covering material so that it is sandwiched and pressed. In this case, the required number (number) of tunnel posts is approximately twice the number of posts that support the covering material. Therefore, the initial purchase cost of the tunnel post is required approximately twice as much as when fixing with a belt.

When the covering material is pressed and fixed with a tunnel support or a string-like belt, etc., the tunnel shape cannot be maintained unless the tunnel support is installed at a narrow interval, and the temperature and humidity Because of the adjustment, it becomes difficult to fix the covering material when the skirt is opened and closed, so it is necessary to install a lot of tunnel posts at narrow intervals. For this reason, not only the required quantity of tunnel posts and the labor for installation are inevitably increased, but also a lot of labor and space are required for cleaning, transportation and storage after use.

Hands are put into the tunnel for work such as topdressing, thinning, and weeding, but because there are tunnel struts, etc., at narrow intervals, the tunnel struts, etc. will be hindered, and a wide range of work cannot be done at once. However, both the mind and body are painful and work efficiency is reduced.

When digging a valley and embedding and fixing the edge to the soil, it is possible to work alone, and the required number of tunnel posts may be small, so the labor for installing the tunnel posts will be reduced, and the purchase cost and use of the posts Later cleaning effort and storage space may be small, but it is fixed by digging around the fence, covering with a covering material, and pressing the edge with soil, so that the edge can be turned up for temperature and humidity adjustment In this case, since there is no portion to be fixed, when the wind blows, the covering material is blown by the wind and the shape cannot be maintained.

The present invention made to solve the above-mentioned problems is an agricultural covering material provided with an insertion portion provided in the belt body, excluding the edge of the belt body, and the belt-shaped coating material is preferably made of sheet resin. Yes, it may be a non-woven fabric or a woven fabric, or it may be a covering material made of a net or the like, or a composite material thereof.

Since there is no need to press and fix the tunnel covering material such as a heat insulation sheet from the top of the covering material like zigzag sewing with a string-like thing such as a rubber belt, a hook etc. for hooking the string-like thing is driven in and installed There is no need. Therefore, not only the labor is unnecessary, but the tunnel shape can be maintained even when the distance between the tunnel posts is wide and the quantity is small.

There is no need to press and fix the tunnel covering material such as a heat insulation sheet from the top of the covering material, so even if the supporting tunnel struts are installed at the same narrow interval as before, the required number of tunnel struts is It can be greatly reduced to about half.

Since the necessary materials and quantity such as tunnel posts are small, it is possible to reduce labor and material purchase costs necessary for installing them. In addition, since the absolute use quantity of the tunnel post may be small, it is possible to reduce the labor, storage space, etc. for transportation after installation and use, cleaning after use.

When a supporting tunnel post is installed at the same pitch as the conventional one, the tunnel post used for fixing the covering material and the string-like object do not exist, so the space between the posts spreads about twice. For this reason, it is difficult to obstruct work such as topdressing and thinning performed by putting the hand into the tunnel, and a wide range of work can be performed at once.

Even if the covering material skirt is turned up for temperature and humidity adjustment, the entire covering material is fixed by fixing the insertion material (wire, etc.) passed through the insertion part on the center side to the piles at both ends of the tunnel. Therefore, not only can ventilation be done without breaking the tunnel shape, but the insertion part on the edge side is not only possible to fix the skirt, but also when it is fixed with a pillar or string-like thing The simple opening and closing work that was possible became possible.

By fixing to the piles at both ends of the tunnel, the entire tunnel covering material can be fixed, so the distance between the tunnel posts is wider than before and the tunnel shape can be maintained even in a small state. Even if work such as topdressing, thinning, weeding, etc. is done with a small number of hands, there are few tunnel pillars, so it will not be hindered, and it will be painless and a wide range of work can be performed without hindrance.

In the installation of the covering material, the entire covering material is fixed if the insertion object (wire or the like) passed through the insertion portion is firmly fixed to the piles at both ends of the rod with a binding wire or a binding band. For this reason, the conventional method requires heavy labor and many materials, so that it can be easily used by many people who have refrained from using it.

If strong winds are expected and reinforcement is required, conventional installation methods such as pressing the edge-side insert into the ground with a peg, etc. make it easy to reinforce and fix it, so that it is exposed to cold air, etc. In some cases, however, the coating material was blown away, but it could become unstable, but it could continue to be used without becoming unstable, and the crop could be covered without being defenseless, and it should continue to be used stably. Can.

Since the entire tunnel covering material can be fixed with the piles at both ends of the tunnel, each of the multiple covering materials can be fixed individually and used at a time. Therefore, for example, in the case of crops cultivated from autumn to spring, insect protection and cold protection are necessary. It is possible to coat without. In addition, it is possible to use a light-shielding or breeding color sheet on the insect-proof or cold-proof covering material only when necessary.

Since the insertion part intersects the column, the inserted object and the column passed through it can be easily bundled and fixed, so that the covering can be fixed more firmly, but only the insertion part is cut. Therefore, the covering material is not damaged and can remain intact, and the function of the covering material is not impaired.

As shown in FIG. 1 and FIG. 2, two insertion parts 2 and three insertion parts 3 are provided on the center side and the edge side along the belt-like shape (longitudinal direction) of the heat insulating sheet for tunnel cultivation or the covering material such as the net. I have.

The length of the strip-like shape (longitudinal direction) of the covering material shown in FIG. 1 is about 0.5 m to 300 m, and the width is about 0.5 m to 6 m, but about 1.8 m is common. is there.

The insertion object (wire) 4 is passed through the insertion part 2 and the insertion part 3 shown in FIG. 2, and the pile 8 is firmly driven into both ends of the rod 9 shown in FIG. 5, and the insertion object (wire) 4 is fastened and fixed thereto. The ends of the covering material 1 are bundled and fixed to the pile 8 with a binding band or a binding wire. As a result, the entire tunnel of the covering material 1 can be fixed. At that time, as shown in FIG. 4 and FIG.

FIG. 4 is a front view (sectional view) of the embodiment. The insert (wire) 4 shown in FIG. 4 may be a single wire or multi-core, but is preferably a hard messenger with a sheath (coating) (7 galvanized steel wires) and a thickness of 5.5 Sq. Although it is sufficient to use the one of about 38Sq, 8Sq ~ 14Sq is more preferable, because it is a wire with tensile strength and moderate elasticity, it can improve workability and improve airtightness, adhesion and restoration, tunnel Increased confidence in insect protection and cold protection.

In the usage example of FIG. 4, the insertion object (wire) 4 is used, but a pipe or the like may be used instead.

The tunnel post 6 shown in FIG. 5 is made of bamboo or the like, or is commercially available, and the material thereof may be easy to use regardless of whether it is metal, wood, resin, or other fibrous materials. Further, the struts are erected so as to straddle the ridges at intervals of about 0.5 m to 2 m, and the covering material 1 of the present invention is put on the tunnel struts 6 so as to cover them. Although this operation is not substantially different from the conventional product of the existing technology, as shown in FIG. 6, conventionally, the covering material is fixed so as to be pressed by the tunnel support 7 from above the covering material 1. However, as shown in FIG. 5, the present invention uses the insertion part 2 and the insertion part 4 shown in FIG. 5 without using the fixing tunnel support 7 shown in FIG. In addition to being able to maintain the airtightness and tunnel shape equivalent to or better than the fixing method using the conventional tunnel post 7 shown in FIG. Compared to the method, there is little compared to the method, and the covering material can be opened and closed easily in a very short time. For this reason, it is very effective at the time of harvesting as well as when managing weeds, top dressing and thinning.

Conventionally, as shown in FIG. 6, the covering material 1 is fixed so as to be pressed by the tunnel support 7. Therefore, in order to work in the tunnel, it is necessary to pick up the skirt of the covering material 1 and work from the narrow gap between the tunnel support 6 and the tunnel support 7, which naturally limits the work range, Although these struts hinder and hinder work, in the present invention, as shown in FIG. 5, there is no fixed tunnel strut 7 shown in FIG. Therefore, even if the columns are installed at the same interval as the tunnel column 6 shown in FIG. 6, the space between the columns is doubled and a wide range of work is possible. However, as shown in FIG. The interval can be made wider than the conventional tunnel post 6 shown in FIG. 6, and the required number of tunnel post 6 can be reduced.

When the soil of the cultivated land has unevenness and it is difficult to adhere, or when the edge of the covering 1 is lifted by the wind, a peg such as the peg 10 shown in FIG. The insert 4 is pressed and fixed. Thereby, although the covering material 1 is pressed and fixed by the fixing tunnel support 7 shown in FIG. 6, since it does not exist, the capacity in the tunnel is not reduced as shown in FIG. In addition, it is strong against wind and the covering material is windy, making it difficult for the crop to be exposed unprotected, thus protecting the crop from pests and cold. It also prevents other accidents caused by smashing nearby crops with windy coverings and flying around in the wind.

FIG. 3 is a front view in which the insertion part 3 shown in FIG. 2 is removed and only the insertion part 2 is provided, and the insertion part 2 is provided as shown in FIG. 3, but one insertion part is provided on the center line. The increase of 3 is very good, leaving the insertion part on the center line, removing the insertion part 2 and making only one. Moreover, like the insertion part 13 of FIG. 10, you may provide between the insertion part 2 and the insertion part 3, and the insertion part 13 should just provide an appropriate position and quantity suitably according to the size of a coating | covering material or a use application. .

FIG. 6 is a side view of a general usage example of a covering material for cold protection or the like until the present invention is made.
As shown in FIG. 6, the tunnel support 6 and the tunnel support 7 are arranged at a narrow interval, but this is necessary for maintaining the tunnel shape and fixing the covering material 1. Therefore, when performing work such as topdressing and thinning, a hand must be inserted through the gap between the columns, and a wide range of work is impossible.

As shown in FIG. 7, if a part of the insertion portion 2 is cut, the tunnel support 6 can be passed between the insertion material 4 and the covering material 1. As a result, since the tunnel support 6 and the covering material 1 are integrated by the insert 4, the tunnel is covered even when the tunnel covering with a long ridge or the edge of the covering material is turned up and the work is performed. The shape and the covering material 1 are more stable, the distance between the tunnel columns 6 can be increased, and the required number of tunnel columns 6 is reduced.

FIG. 8 is a front view of a use example in which a plurality of coating materials 1 are used at the same time. Each coating material 1 is shown in FIGS. 1 and 2. However, it is not necessary for each covering material to have the same function, and it is possible to use a covering material having different functions. For example, an insect net and a cold protection sheet are stacked and cooled. If it is present, a coating material such as a cold protection sheet can be further formed thereon, and a color sheet for light shielding or growth can also be used.

Although the insertion part 11 and the insertion part 12 of FIG. 9 are not continuous like the insertion part 2 and the insertion part 3 of FIG. 1, they are functionally the same, and the insertion part 11 and the insertion part 12 of FIG. This is an insertion part having an intermittent structure. Therefore, the insert 4 passed through each insertion portion may be the same as the insert 4 shown in FIG.

In many cases, the conventional covering material is difficult to work by one person. Moreover, if the wind blows even a little, the difficulty increases even more, but the product of the present invention is inserted into the insertion portion. Since it is used through objects, it can be covered by one person with its elasticity and weight.

In the covering material in FIG. 1, four insertion portions (insertion portion 2 and insertion portion 3) are provided, but the insertion portion may be one, and the insertion portion 2 and insertion portion in FIG. 9. 3, 4 or more like the insertion part 13 may be sufficient.

In the covering material of FIG. 2, the insertion object (wire) 4 is passed through the insertion part 2 and the insertion part 3, but the insertion object 4 may be directly attached to the covering material without using the insertion object. .
