Description

[Detailed explanation of the invention] [Industrial application field] This invention is used to store agricultural products such as cover land for storing agricultural products, especially sugar beets piled up in the open after harvesting, and yams and potatoes buried in the soil. This relates to cover land for storing agricultural products.

[Conventional technology]

Traditionally, plain weave fabrics made from flat yarns as weft and weft have been commonly used as covers for storing this type of crop. However, as is well known, in northern Japan, crops are harvested in the fall and then buried in the soil, or dug up and piled up in the open, and then covered and stored until the following spring. However, because the above-mentioned covers have poor thermal insulation properties, crops stored in extreme cold suffer from frostbite and other problems, and the initially intended storage effect is not achieved.

Therefore, the inventor of this invention proposed a cover fabric made of a fabric woven with foamed spread yarn, which has excellent heat retention, as the diameter and weft, instead of the above-mentioned cover fabric, and this came to be used, but due to climatic conditions. In order to survive the severe cold of northern countries, it is necessary to stack multiple sheets and cover them with synthetic resin sheets, which makes handling such as covering work extremely complicated.

[Problem that the invention attempts to solve]

Therefore, the creator of this device proposed a cover material for storing agricultural products in which a synthetic resin sheet was layered on one side of the above-mentioned cover material, but it could not be said that it was necessarily satisfactory in terms of heat retention during severe cold weather. .

This invention was devised to solve the problems of the conventional products described above, and aims to provide a cover material for storing agricultural products that has excellent heat retention as well as ease of handling.

[Means for solving problems]

This invention was devised in view of the above, and is a cover material for storing agricultural products, which is made by laminating a synthetic resin sheet on one side of a woven fabric made of expanded expanded yarns in diameter and weft. A cover material for storing agricultural products, characterized in that it consists of front and back woven fabrics that are joined together with a binding yarn made of a thread-like part of the woven fabric or an inserted thread so as to form a predetermined empty space between them. It is.

〔Example〕

The following describes the embodiment of the present invention as shown in the drawings.
More specifically, FIG. 1 is a partially cutaway perspective view showing one embodiment of the crop storage cover of this invention, and FIG. 2 is a partially enlarged sectional view of the same.
In the figure, 1 and 2 are front and back fabrics 3.6 m wide and 300 m long, woven with 3000 denier polypropylene expanded spread yarns at a ratio of 10 yarns per inch for diameter and weft, 3 is a void formed between the layered front and back fabrics 1 and 2, 4 is a binding yarn which binds the layered front and back fabrics 1 and 2 together, and is bound at intervals of 3 inches by a part of the thread of the front fabric 1, 5 is a 80 μm thick yarn layered on the surface of the front fabric 1.
It is a synthetic resin sheet made of a polyethylene sheet.

As shown in Fig. 3, the agricultural product storage cover area of this invention has a synthetic resin sheet 5 on the top surface of the agricultural products A that are piled up in the open so that the width is 10 m, the height is 3 m, and the length is about 200 m. It is used by covering the cover material so that it is located at the center of the cover and fixing its peripheral edge with a wedge or the like.

[Effect of idea]

The cover fabric for storing agricultural products of this invention combines the thermal insulation properties of the foam spread yarn itself with the thermal insulation properties of the voids formed at a predetermined interval between the front and back fabrics, and the cold air blocking properties of the synthetic resin sheet. As a result, heat retention has been further improved, and since the synthetic resin sheets for the front and back fabrics are integrated, three layers of cover can be covered at the same time without shifting, which is better than conventional products. The sheet hanging work is significantly improved compared to the conventional method.
