Description

[Detailed Description of the Invention] The present invention relates to a protective cover for protecting agricultural crops from frost, snow, rain, strong sunlight, etc.

Conventionally, this type of protective cover has been ■Paper.

One wire is inserted through a synthetic resin film or a synthetic resin foam sheet such as polyethylene, and the other is a wire bent into a U-shape or V-shape and sewn into two straight parts of the synthetic resin foam sheet. Insert it through the
A well-known example is one made by bending a sheet.

In addition, a protective cover has also been proposed in which a hard synthetic resin foam sheet is provided with a hinge for folding in two in the middle, and strips extending into the soil are connected to both ends on the ground side.

FIG. 1 shows a specific example of the above (2), and FIG. 2 shows a specific example of the above (2).

In the case shown in Figure 1, only the top and two sides of the crops are covered, and in the case shown in Figure 2, only the top and one side are covered, so they are effective in protecting against frost, snow, and sun, but they are not protective. It was not possible to prevent the wind from passing through the cover and causing the board to break.

Therefore, in cold weather, especially at night, the temperature inside the protective cover becomes similar to that of the atmosphere, so there is a drawback that the growth of agricultural crops cannot be promoted.

In other words, in order to maintain the growth of agricultural crops, it is necessary to maintain the temperature around the crops at an appropriate temperature, which requires greenhouse cultivation, which requires a great deal of labor and expense.

Furthermore, there was a problem in that it had little protection against flying pests, and the fertilizer ran off during rain.

The present invention is a protective cover for agricultural products devised in view of the above, in which the main body is formed of a synthetic resin sheet, side pieces are integrally extended on both sides of the cover via a bending hinge, and the cover is provided near the hinge. A slit is provided to the end of the side piece, and a wire is inserted through the center of the main body so as to be sewn parallel to the hinge part.When in use, the side piece is bent from the hinge part and covered by the main body. The aim is to protect the entire surface area of agricultural crops by covering two sides of the crops, thereby solving the above-mentioned problems.

Next, an embodiment of the present invention will be described based on FIGS. 3 to 5.

In FIG. 3, 1 is a synthetic resin sheet, and the sheet 1
By providing the bending hinge parts 4, 4 consisting of 20 grooves in the , the side pieces 3 are formed on both sides, and the main body 2 is formed between both the hinge parts 4, 4. 3 end 7
This is a protective cover in which a slit 6 is provided, and an easily deformable wire 5 such as a steel wire is inserted through the center of the main body 2 so as to be sewn together with the hinge part 4, so that the front and back sides appear alternately.

The agricultural crop protection cover formed in this way is made by bending the main body 2 at the center to form an approximately V-shape or U-shape, as shown in FIGS. Both ends are placed in the soil where the crops are planted to cover the crops 8.

At this time, as shown in the figure, the side piece 3 is brought into a state in which the hinge portion 4 covers the two sides that cannot be covered by the bending main body 2.

In this case, since the hinge portion 4 and the slit 6 are provided, it is possible to easily bend the side piece 3 even when the main body 2 is bent using a sheet made of a relatively strong material.

Further, if the synthetic resin sheet that is the material of the side piece 3 is flexible, it will naturally hang downward without needing to be bent.

Therefore, the slits 6 may be provided as appropriate depending on the flexibility of the sheet material used.

Another example of a protective cover having such characteristics is one in which the side piece 3 is made thinner than the main body 2 by extrusion molding or the like in order to more easily bend the side piece 3 in a direction perpendicular to the main body 2. , in this case as well, the same effect as in the above embodiment is exhibited.

In the above embodiment, the main body 2 and the side pieces 3 are rectangular as shown in the figure, but they may also be of various shapes suitable for covering crops, such as square, diamond, or round. Can be used.

Further, the cross-sectional shape of the hinge portion 4 may be other than the triangle shown in the figure, such as a round trapezoid or the like.

Furthermore, in order to cover the entire ground area of the crops 8, wide side pieces 3 may be used, and if a part of the sides of the crops 8 are left open as shown in FIG. side piece 3
It is sufficient to use

The synthetic resin sheets used in this invention include polyethylene, polypropylene, and polyvinyl chloride.

Polystyrene, ethylene-vinyl acetate copolymer.

Foamed or non-foamed synthetic resins such as ethylene-vinyl chloride copolymer or synthetic resin foams of the above materials are preferably laminated with a synthetic resin film, but are not particularly limited to these. Any synthetic resin may be used as long as it has good shape retention to the extent that it can be used as a cover.

The crop protection cover of the present invention is constructed as described above, and when the main body 2 is folded in the middle to cover the crops, the side pieces 3 are bent from the hinge part 4 and the cover is covered by the main body 2. This protects the entire above-ground part of the crops by covering the unprotected sides, but since the hinge part 4 and the side pieces 3 are provided with slits 6, even if a sheet made of a strong material is used.
The side pieces can be easily bent while the main body 2 is bent.

In addition, the protective cover of this invention protects crops from frost and snow. Not only can rain 9 be more protected than before from strong sunlight, but the inside of the protective cover can be kept warm by preventing wind from passing through the inside of the protective cover, and the growth of agricultural products can be promoted.

That is, even in cold weather, especially at night, the temperature around the crops does not drop much because the wind is prevented from passing through, making it possible to easily create a condition similar to a greenhouse.

Furthermore, it has the effect of solving problems that could not be solved in the past, such as damage caused by flying pests and fertilizer runoff during rain, and it is easy to handle and can be used efficiently. have.
