Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cotton cover, and more particularly to a cotton cover for waterproofing and windproofing while compressing raw cotton and storing it in a predetermined shape for a predetermined period of time. It relates to a cotton cover to be coated.

[0002]

2. Description of the Related Art In many cases, raw cotton collected from a cotton field is stored for 2 weeks to half a year as a cotton module compressed and formed into a predetermined shape before being sent to a cotton mill. The cotton module still contains the seeds of the raw cotton, it needs to be waterproofed to germinate due to moisture such as rainwater and reduce the quality of the raw cotton, and because it is piled up, it prevents scattering by the wind Measures are needed. The cotton module is usually a rectangular parallelepiped of about several to 10 tons, which is suitable for being directly transported by a truck container.
It has a shape like a height of 2.3 m.

As a method of covering the cotton module, a method of covering the surface with a sheet or a cross sheet made of a waterproof synthetic resin and tying it with a rope or the like can be considered. In the method in which the sheet is tightly fitted to the rectangular parallelepiped, folded, and the rope is wound and fixed, there is a problem that the positioning of the sheet is difficult, the workability is poor, and the sheet is peeled off by wind pressure or contains wind. Therefore, various shapes of covers according to the shape of the rectangular parallelepiped have been tried.

[0004] Many of the conventionally known covers are formed by sewing one sheet so as to cover the upper part of the rectangular parallelepiped. However, when the cover is shallow, the cover is lifted by wind from the side. When the cover is deep, installation is troublesome when the cover is deep, and when transporting this cotton module in a truck container, the cotton module is scraped up by a conveyor provided at the bottom of the container and pulled in the longitudinal direction. There was a problem that it was stretched and damaged with it.

[0005] As described above, the raw cotton needs to be waterproof, and the rainfall on the ceiling surface of the cotton module is soaked into the inside of the cotton module and causes the quality to deteriorate. Since the raw cotton has oil and fat attached thereto and has water repellency, there is a case where a coating is not necessarily required around the lower part of the cotton module except for high quality cotton.

In order to prevent the cover from peeling off due to the wind, a connecting cord is provided at the lower edge of the side surface of the cover to be engaged with a locking member provided at the lower end of the cotton module or the side surface of the cover. Is also known as a mesh sheet, but there are problems such as difficult handling, insufficient locking effect, and excessive cost for production, and further improvement is desired. I have.

It is preferable that at least one bag 8 containing a string 7 for tightening the periphery of the cotton cover 1 in the horizontal direction is formed in advance on the three sheets. In the figure, the bag 8 is provided in the horizontal direction near the end. This bag 8 can be preferably provided by welding the same long material as the main body sheet. At this time, it is desirable to incorporate the cord body 7 inside the bag body 8 to be formed in advance. The bag body 8 has a function of supporting the cord body 7 that tightens the periphery, and does not necessarily have to be a continuous long body, and is constituted by a plurality of bag bodies 8 that are partially present in the horizontal direction. You may. In the figure, the bag bodies 8 are provided at two parallel positions, but the number is not particularly limited. It is preferable that an end of the sheet of about 100 to 300 mm hangs below the lowermost bag body 8 provided in the horizontal direction to form a skirt portion 9. By forming the skirt portion 9 in this manner, the cord body 7 contained in the bag body 8 is formed.
When the cover is tightened and the cover is squeezed from the surroundings, the end of the skirt portion 9 faces outward, and rainwater or the like that has fallen along the skirt portion 9 causes the side surfaces 4, 4 'and the front and rear surfaces 5, It will fall outside 5 ', and will improve waterproofness.

On the front surface 5 or the front and rear surfaces 5 and 5 'of the cotton cover 1, a belt 7 is used to tighten the cord body 7 which is circling around the cotton cover 1.
The woven fabric belt 1 is used as the cord body 7 used for the belt fastener 10.
