DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stop rod for an agricultural cover sheet for fixing an agricultural cover sheet between upper and lower stopper rods and a method of using the same.

[0002]

2. Description of the Related Art A conventional agricultural covering sheet is constructed by alternately planting lower and upper supporting rods of a covering sheet at regular intervals.
It was most common to lay a cover sheet between the upper and lower support rods.

[0003] In such a case, in many cases, a rope is put on the cover sheet, and care is taken to prevent the cover sheet from flying even if there is a gust or the like.

[0004]

According to the conventional method, since the cover sheet is stretched on the lower support rod,
Although the distance to the ground is maintained for a time, if the use period is prolonged, there is a risk that the plants may be exposed due to slack or sometimes the lower and upper support rods may come off due to a gust of wind.

[0005] Also, by holding with a rope (rope), it is possible to keep the shape in a predetermined shape for the time being, but when looking at the inside of the tunnel or caring for plants, the rope must be removed each time. There were problems such as requiring a lot of time and labor. There is no other alternative to the above.

[0006]

According to the present invention, the work for clamping and fixing the cover sheet and the partial opening of the tunnel are performed by fitting and using the lower stop rod and the upper stop rod instead of the upper and lower support rods. The time and effort needed to save significant time.

That is, the present invention relates to a synthetic resin made of synthetic resin having a V-shaped or U-shaped cross section having a concave portion capable of holding a cover sheet .
A lower stop rod and an upper stop rod having the same shape as the lower stop rod made of synthetic resin which is fitted and fixed in a recess of the lower stop rod and clamps the cover sheet. This is the stop rod for the agricultural cover sheet .

[0008] Next, the invention of the method of use is such that the cross-sectional shape is V-shaped or at regular intervals along the tunnel forming portion by the cover sheet.
The U-shaped synthetic resin lower stop rod is formed in an arc shape, and both ends are implanted in the ground, and a transparent vinyl sheet is laid on the lower end of the arc shape to form a tunnel-shaped cover. Next, a synthetic resin upper stop rod having the same shape as the lower stop rod is fitted directly above the lower stop rod, and the cover sheet is sandwiched and fixed,
A method of using the stopping rod of the agricultural covering sheet, wherein both ends of the upper stopping rod are planted in the ground.

In the above, the lower stop rod and the upper stop rod have the same shape and, for example, may be cut into a predetermined length after extrusion molding, so that there is an advantage that mass production can be performed at low cost.

The lower and upper stopping rods can be previously formed in an arc shape if their radii are determined. If it is formed in advance, it is not necessary to bend every planting, so that the installation labor time can be saved.

In the present invention, since the cover sheet is sandwiched and stretched by the lower stop rod and the upper stop rod having the same shape, there is no possibility that the cover sheet is stretched and slackened. There is no risk of peeling or partial peeling.

Further, according to the present invention, the lower stop rods are linearly arranged in parallel, a cover sheet is laid thereon, and the upper stop rods are fitted and fixed to the lower stop rods to complete the work. There is also an advantage that work can be easily performed in a short time and by one person.

[0013]

An embodiment of the present invention will be described with reference to FIGS. The lower stopper rod 1 made of synthetic resin having a V-shaped cross section is planted in a semicircular shape as shown in FIGS. The length of the lower stop rod 1 varies depending on the size of the tunnel.
cm, thickness 0.3cm, height 2cm, opening angle 30
Degree. After the lower stop rods 1 are arranged in parallel at a predetermined length with an interval of 100 cm, a transparent vinyl sheet 2 is attached thereon, and the lower stop rods 1 and 1 are respectively attached to the upper stop rods 3 and 3. (FIG. 3) is an example of the state of use of the present invention. In the above description, the upper edge of the vinyl sheet 2 is slightly buried in the ground on the ground 4 and the vinyl sheet 2 is pulled when the upper stop rod 3 and the lower stop rod 1 are fitted. Can be fixed.

In the above, in order to open a part of the vinyl tunnel 5, if the upper stop lever 3 at the position to be opened is taken, the vinyl sheet 2 is also slackened, so that the work is easy. In the figure, 6 is a ridge and 7 is a plant.

In the above embodiment, the upper stop rod 3 and the lower stop rod 1 have the same shape, but the shapes may be changed. If the shapes are the same, the molds can be made the same and timely.

[0016]

In the above-mentioned embodiment, the stop rod has a V-shaped cross section. However, the cross-sectional shape of the stop rod of the present invention is not limited, and the shape is not specified, as long as it can sandwich a vinyl sheet.

FIG. 5 shows an embodiment of the stop rod.
5A shows a U-shaped stop rod 8 and FIG. 5B shows a dish-shaped stop rod 9.
Der Ru.

As shown in FIGS. 7 and 8, a conventional cover sheet has a lower support rod 13 planted on the ground at a predetermined interval, a vinyl sheet 2 stretched thereon, and an upper support rod 12 thereon. Is installed in the middle upper part of the lower support rods 13, 13. Therefore, although it supports the top and bottom for a while, the mutual interval is wide (for example, 50 cm), and it is likely to be blown off when the wind blows,
Means had to be added, such as holding a rope in a cross shape, and adding means, such as fixing a peg to the ground at the long edge. Therefore, not only a great deal of labor and time are required for producing the tunnel of the cover sheet, but also when the operation is performed while opening the middle part of the tunnel, there is a complicated operation that has to be repeated.

However, according to the present invention, it is possible to make the tunnel as expected with relatively little material, and it is also easy to open the middle part of the tunnel, and to make a great contribution to the creation of the tunnel with the cover sheet. I did it.

The curved shapes of the lower stop rod and the upper stop rod described above can be formed so as to match the cross-sectional shape of the ridge as shown in FIGS. 6 (a), 6 (b) and 6 (c).

[0022]

However, if the lower stop rod and the upper stop rod have the same shape, it is not necessary to sort them in operation and there is no possibility of excess or deficiency.

The material of the stop rod is preferably a commonly used vinyl chloride resin or other tough resin which has elasticity and weather resistance, and is preferably, for example, resin-coated iron, aluminum, synthetic resin, or the like. Wires or strips such as rubber or resin treated wood can also be used.

[0025]

According to the present invention, the cover sheets have the same shape.
The lower stopping rod and the upper stopping rod allow the tunnel to be firmly held, workability is good, and partial opening and closing are easy.

[0026] Since the material of Tome杆was extruded material such as a synthetic resin, which simply only cut into a predetermined size, automatically has the effect capable of large quantities manufactured produced, the lower stopper rod and top end stops By making the rods have the same shape, there are also various effects such as that all operations can be completed with one type of stop rod.
