[Industrial applications]

 The present invention relates to a winding device for a vinyl film covering a greenhouse.

[0002]

[Prior art]

 So-called vinyl greenhouses are used to grow flowers and vegetables. A vinyl house is a framework made of metal or synthetic resin such as vinyl covered with a transparent transparent synthetic resin film such as a thin vinyl film. In a greenhouse, since the space is covered with a transparent film and the air flow is small, the heat of sunlight shining into the house is retained in the space, and the internal temperature of the space can be kept higher than the outside air.

However, when the sunlight is strong like midsummer and the sunshine duration is long, the internal air temperature becomes abnormally high. For this reason, it is necessary to adjust the temperature. Usually, the transparent film on the side wall or ceiling of a vinyl house is rolled up in a predetermined area, and the air flow is adjusted to adjust the internal temperature.

FIG. 7 is a partial perspective view of a conventional vinyl house, and FIG. 8 is a partial side view of a conventional vinyl house. In these drawings, 1 is a column, which is erected from the ground at the four corners of the vinyl house. 2 is a side frame that constitutes the side wall of the vinyl house. Reference numeral 3 is an entrance, and 4 is a ceiling frame member constituting a ceiling. A transparent film 5 made of vinyl resin is attached to the side wall. Reference numeral 6 denotes a ceiling surface sheet laid on the ceiling frame member 4, which is made of a transparent film made of vinyl resin. A winding rod 7 is fixed to the lower end of the ceiling sheet 6, and a gear box 8 is attached to the tip thereof. The gear box 8 is provided with a worm gear mechanism, and when the angle-shaped rotary drive rod 9 provided in the gear box 8 is rotated, the winding rod 7 can be rotated. Therefore, when the rotation driving rod 9 is rotated, the winding rod 7 is rotated, and the ceiling sheet 6 is wound around the winding rod 7 to open the air flow window 10 on the ceiling surface, and the size of the air flow window 10 is increased according to the winding amount. You can adjust the height.

[0005]

[Problems to be Solved by the Invention]

 In the conventional winding device as described above, as shown in FIG. 7, the sheet roll 11 on which the ceiling sheet 6 is wound in the free state is rewound due to its own weight, and the rotation drive rod 9 draws a large arc. In order to avoid being swung around and injuring others, the rotary drive rod 9 must be made long and heavy to some extent to increase the rotational moment. Further, the distance D from the side surface of the ceiling to the gear box 8 must be 50 cm or more so that the operator 12 can freely and easily rotate the rotation driving rod 9, and therefore the winding rod 7 Bends due to the weight of the gear box 8 and the rotary drive rod 9, and a large driving force is required at the time of winding. It causes the inconvenience of speeding up. Further, since the gear box 8 and the hoisting rod 9 are largely projected from the side surface of the greenhouse, there is a risk that the worker 12 is obstructed to pass through or the worker 12 collides with them at night and causes an accidental injury. There is also.

The present invention is intended to eliminate the above-mentioned conventional inconveniences, and an object thereof is to prevent a gear box from significantly protruding from a side surface of a vinyl house and to provide a winding driving force in a vinyl house winding device. It is to provide a compact vinyl house winding device that requires less.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object of the present invention, the present invention provides an area for covering the ceiling surface of the ceiling sheet by rotating the winding rod attached to the lower end of the ceiling sheet covering the ceiling of the greenhouse. In a variable winding device for a greenhouse, a gear box for converting the rotation direction of the winding rod to a right angle direction, a rotary drive rod for rotating the winding rod connected to the gear box, a winding rod and a gear box. , A universal joint provided on at least one of the gear box and the rotary drive rod, and a clamp provided on the side wall of the greenhouse for holding and sandwiching the rotary drive rod. The present invention provides a winding device for a vinyl house, which is characterized by:

[0008]

[Action]

 When the ceiling sheet covering the ceiling of the vinyl house is rolled up or rolled down, the rotation driving rod is pulled away from the clamp, the handle part at the tip is moved far away from the side wall of the vinyl house, and the handle is rotated. Since a universal joint is provided between the winding rod and the gearbox and between the gearbox and the rotation drive rod, the ceiling sheet can be easily rolled up or rolled down by rotating the handle portion. be able to. When not using the rotary drive, clamp it in the clamp to prevent unnecessary movement.

[0009]

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partial side view showing an embodiment of the present invention. In the embodiment of the present invention, the same parts as those in the conventional example are designated by the same reference numerals, and the description thereof will be omitted. As is apparent from FIG. 1, a first universal joint 20 is attached to the tip of the hoisting rod 7 extending from the sheet roll 11, and the hoisting rod 7 and the gear box 8 are coupled via the universal joint 20. is doing. A second universal joint 22 is coupled to a rotary shaft 21 extending downward from the gear box 8, and a rotary drive rod 9 is coupled to the universal joint 22. Reference numeral 23 is a grip portion rotatably fitted in the rotary drive rod 9, and reference numeral 24 is a handle portion.

A mounting frame 26 is provided on the side wall of the vinyl house substantially parallel to the inclined surface 25 of the roof. A plurality of clamps 27 for holding the rotation driving rod 9 are attached to the mounting frame 26. These clamps 27 are U-shaped and are made of a metal rod having a spring property. Then, when the rotation driving rod 9 is pressed against this, the rotation driving rod 9 is sandwiched between the U-shaped arms and held by the mounting frame 26 as shown in FIGS. 2 and 4. When the roll sheet 6 is rolled up or unwound, the rotary drive rod 9 is pulled away from the clamp 27 and pulled out in the direction of arrow A as shown in FIG. At this time, the first universal joint 20 is provided between the hoisting rod 7 and the gear box 8, and the second universal joint 22 is provided between the gear box 8 and the rotary drive rod 9, so that FIG. As shown in FIG. 4, the operator 12 can easily rotate the rotation driving rod 9 in the arrow B or C direction by holding the grip portion 23 and the handle portion 24 away from the greenhouse. . After use, as shown in FIG. 4, if the rotation driving rod 9 is sandwiched between the clamps 27, the wound sheet roll 11 is naturally unwound and the rotation driving rod 26 is swung carelessly. In addition, the wind does not cause the rotary drive rod 26 to sway and collide with the worker 12.

Since the first universal joint 20 and / or the second universal joint 22 are provided, the distance L between the side wall of the vinyl house and the gear box 8 can be made smaller than the width S of the handle portion 24. . Therefore, the hoisting rod 7 does not bend due to the weight of the gear box 8 and the rotation driving rod 9.

In the above embodiment, the first universal joint 20 is provided between the hoisting rod 7 and the gearbox 8, and the second universal joint 22 is provided between the gearbox 8 and the rotary drive rod 26. However, as shown in FIG. 5, only the first universal joint 20 may be provided between the hoisting rod 7 and the gear box 8, or as shown in FIG. It is also possible to provide two universal joints 22 between the rotary drive rod 26 and the rotary drive rod 26.
