Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotary opening / closing curtain device for a greenhouse in which a curtain for heating or shading is attached to the ceiling side of the greenhouse so as to be openable and closable.

[0002]

[Prior art]

 In general, greenhouses for greenhouse cultivation were constructed by assembling a rectangular frame made of steel, installing film fixing tools in a tree shape at appropriate intervals, and covering this with a transparent film. Especially in greenhouses in cold regions, the temperature inside the greenhouse drops at night, so there are places where heating is done only at night, but the air warmed by heating rises to the ceiling side, so the air around the crop is hard to warm up. , Had to raise the heating temperature.

For this reason, a curtain is installed above the crop so as to be openable and closable, and the curtain is closed at night so that the air heated by heating does not escape to the ceiling side to save energy. Also, during summer days when the sun's rays are strong, the temperature in the greenhouse rises and plants weaken, and in the case of crops that are cultivated in the shade, such as mushroom cultivation, the opaque shading curtain can be opened and closed freely. It may be attached to.

[0004] Such a curtain for heating or shading has a pulley attached to the ceiling side of a rectangular greenhouse, and a wire supporting the curtain is passed through this, and this wire is wound by a winding drum to be opened and closed. , For example, it has a structure that opens and closes left and right from the center of the greenhouse. However, when building a greenhouse on a small land, if the greenhouse is formed in a flat polygonal shape or a flat circle, the conventional curtain opening / closing structure opens and closes to the left and right, leaving a gap at the periphery and completely covering it. This is not possible, and even if heated, warm air escapes to the ceiling side and the heating effect deteriorates.

[0005]

[Problems to be solved by the device]

 The present invention has been made in view of the above point, and when the greenhouse is formed in a flat polygonal shape or a flat circular shape, energy saving can be achieved when the entire ceiling side is covered with heating or a curtain for shading without a gap. In addition to the above, it is intended to provide a rotary opening and closing type curtain device for a greenhouse which can be automatically opened and closed.

[0006]

[Means for Solving the Problems]

 The invention according to claim 1 of the present invention comprises a greenhouse formed in a plane polygonal shape or a plane circle, a center pillar standing upright in the center of the greenhouse, and a rotary mounting plate mounted on the center pillar and rotated by a motor. , A plurality of opening / closing bars radially provided on the rotary mounting plate, a plurality of mounting bars radially installed between the opening / closing bars toward the inner wall of the greenhouse from the center support, and the opening / closing bars. It is characterized by comprising a substantially fan-shaped or substantially triangular curtain with one side connected and the other side connected to a mounting rod.

Further, the invention according to claim 2 is such that a greenhouse formed in a planar polygonal shape or a circular shape in a plane, a center pillar standing upright at the center of the greenhouse, and a rotary mounting plate rotatably mounted on the center pillar. A plurality of opening / closing bars radially protruding from the rotary mounting plate, a plurality of mounting bars radially installed between the opening / closing bars toward the inner wall of the greenhouse from the center support, and the opening / closing bars. A substantially fan-shaped or substantially triangular curtain with one side connected and the other side connected to a mounting rod, pulleys provided along the inner wall of the greenhouse at predetermined intervals, and the pulleys are moved to guide the opening and closing. It is characterized by a wire connected to the tip of the rod, a wire feed drum for feeding this wire, and a motor for rotating the wire feed drum.

[0008]

[Action]

 According to the first aspect of the present invention, in the rotary opening / closing type curtain device for a greenhouse, when the night heating device is operated, the curtain is opened like an umbrella, and the ceiling side above the crop is closed so that the warm air is upward. Do not escape to enhance the heating effect. When the sun comes out in the morning, drive the motor to rotate the rotating mounting plate that is rotatably attached to the center column. As a result, the opening and closing rods protruding in a radial direction rotate by a predetermined angle, and the curtain with one side connected to it is folded and brought closer to the fixed mounting rod side to reduce the shade of the sun and the sunlight to the product sufficiently. It is supposed to be irradiated. Also, when driving the heating at night, reversing the motor and returning the open / close bar causes the curtain to spread like an umbrella and shield the space above the crops.

Further, in the rotary opening and closing type curtain device for a greenhouse according to claim 2 of the present invention, when the sun comes out in the morning, when the motor is driven to rotate the wire feed drum, the wire moves. For this reason, the wire connecting part at the tip is pulled and the opening / closing bar rotates by a predetermined angle, and the curtain attached here is folded and brought close to the side of the mounting bar to stop, so that the crop is sufficiently exposed to sunlight. It is supposed to be irradiated.

When the sun comes out in the morning, when the motor 7 is driven, the gear 4b attached to this rotating shaft rotates and the gear 4b meshing with this rotates, and the gear is attached to the center support 2 by rotation. The rotating mounting plate 10 rotates. As a result, the opening / closing bars 11 ... Radially protruding are rotated by 45 degrees. At this time, one side of the curtain 16 is attached to the rotating opening / closing bar 11 and the other side is attached to the fixed mounting bar 14. As shown in FIG. 5, the opening and closing bar 11 is stopped by being folded and moved to the side of the mounting bar 14 so that the shade of the sun is reduced and the crop is sufficiently irradiated with sunlight. When heating is performed at night, the curtain 16 can be opened like an umbrella and shielded by reversing the motor 7 and returning the opening / closing bar 11.

In the above embodiment, the structure is shown in which the tip side of the opening / closing bar 11 is supported by the hanging wire 12, but the tip side of the opening / closing bar 11 is supported by the rail and is not supported on the rail. A guide structure is also acceptable.

6 to 8 show another embodiment of the present invention, in which a center pillar 2 is erected in the center of a greenhouse 1 formed in a plane octagon, and the center pillar 2 has a ceiling side. As shown in FIG. 7, a cylindrical ring 3 is rotatably attached via a bearing, and a lower portion of the cylindrical ring 3 is supported on a support bracket 5. A circular flange 8 is joined to the outer circumference of the cylindrical ring 3, and eight open / close rod attachment portions 9 are provided on the upper surface of the circular flange 8 to form a rotary mounting plate 10. Further, the middles of the eight opening / closing bars 11 ... that are radially projected are connected to each other by connecting bars 13 ...

As shown in FIG. 7, the opening / closing rod 11 has a small diameter pipe 20b slidably attached to the end of a large diameter pipe 20a so that the length of the opening / closing rod 11 can be adjusted.
