[0002]

2. Description of the Related Art A greenhouse for cultivation used for greenhouse cultivation of vegetables is one in which a transparent or semitransparent polymer film is spread on a steel frame. The film used here generally has a thickness of 75 to 150.
A soft film made of vinyl chloride resin or polyolefin resin having a thickness of 4 μm and having a width of 4 to 12 m and a length of 20 to 100 m is used. Such a film is spread so as to cover a steel frame having an eave height of 2 to 8 m, an iron pipe, or a wooden house frame.

At the time of expansion, an operator climbs on the frame of the house to pull the film or put it on the roof. In this case, there are many work in high places where the scaffolding is poor, usually 5
It requires a large number of 10 people, and it takes a relatively long time to expand one building. Also, once the wind blows during the spreading, the film seems to have caught the sail, and if you forcibly spread the film, the film for that may be torn, or the person doing the spreading work may be blown off and seriously injured. is there. Therefore, such work is usually performed on a calm day.

In order to suppress the fluttering of the film after being stretched, a retaining cord is thrown from the side of the house to the opposite side of the film, for example, by throwing one by one over the roof at intervals of 40 to 50 cm. ing.

[0005]

According to the conventional method of spreading a house film, there are the following problems.

(1) A heavy, long and unwieldy film must be placed and spread on the roof frame.

(2) Workers must climb and work in high and dangerous places where the skeleton of the house is poorly scaffolded.

(3) The film cannot be spread without gathering human hands.

(4) When the wind blows, the film spreading operation cannot be performed.

(5) Even if the film is torn after being stretched due to strong wind or deterioration of the film, the film cannot be re-attached immediately unless the weather and human hands are endowed.

(6) The double-rolled or gusset-rolled film has to be spread on the frame of the house or unraveled in advance so that the work is very difficult.

(7) Not only is it time-consuming to attach the film presser string, it takes time to stretch the film, and it is not possible to deal with the case where the wind suddenly blows immediately after coating the film.

(8) When the film is stretched, there is a problem that the person who stretches the film must be restrained and secured because it is easily affected by the weather, especially the wind.

Therefore, the work of climbing on the frame of the house and stretching the film is not necessary, and it is possible to eliminate unsafe work. In addition, it becomes possible to spread the film by one person, and it becomes possible to freely select the time and spread the film at any time without relying on others. In addition, even if the film is torn or needs to be replaced, it can be dealt with promptly. In addition, since unsafe work is eliminated and the film can be spread even by one person, it is not necessary to gather a large number of workers in advance before spreading.

By using a rotating tool using a reduction gear or a rotating tool using power, the film can be spread in a short time. Also, when the film is spread from the side of the house, if the end of the double-wrapped or gusset-wound film that is not spread is attached to the side of the house, the film can be spread and spread on the frame. For this reason, it is possible to omit the work of unwinding a wide film.

On the frame of the house, a storage tool extending in the lengthwise direction is provided at a predetermined height position on the side surface, and a rope,
According to the structure in which the film is attached to the wire or the belt via the film stopper, and the film stopper is stored in the storing tool when the film is stretched, the film width is about half and the weight is half. As a result, the work load for spreading is further reduced, and the problem of transporting heavy and long agricultural films can be solved.

A film retainer string or a film retainer net is provided to cover the film from the outside, and the film retainer cord or the film retainer net is stretched at the same time as the film, or the film retainer cord or the film retainer net is stretched in advance, According to the structure in which the film is stretched between the frame of the house and the film retainer string or the film retainer net, the film retainer string or retainer net is installed especially before the film is stretched, and the film retainer string or net and the house are retained. By stretching the film with the framework of the, it becomes possible to stretch even when the wind blows.

When the film is stretched, a film retaining cord or a retaining net is attached on the film to be extended, and a film retaining cord or a retaining net on the opposite side of the mounting position is wrapped around the film and attached at an appropriate position. When stretched with, the film being stretched does not swell more than the length of attachment of the film retainer string or net, and it can be stretched without difficulty even if the wind blows.

By using such a device, the installation time of the film retainer string after the film is spread can be omitted, and the finish of the film spread can be greatly shortened. In addition, the film just stretched will not be blown away by the wind while the film retainer string is installed, and the film will not have to be redone.

Further, after the film is stretched by the rotary shaft installed on the side of the house, the film presser string is attached to the take-up shaft, and the film presser string is loosened or tightened to wind up the film near the ceiling for ventilation. At the same time, the film wound by the film pressing string or the film pressing net is fixed.

By connecting the film winding shaft according to the present invention to each other between the multi-story houses, several houses can be spread at once, and the film can be efficiently spread in a short time. Further, by using this device, it can be applied to the extension of a tunnel, the ventilation of a tunnel in a house, the opening and closing of a lining curtain in a house, and the like.
