  The ventilator for a cultivation house facility according to the present invention will be described with reference to FIGS. 1, 4, and 6. The ventilator 1 for the cultivation house facility includes a doorway 3a, a side doorway 3b, 3c, and a roof of the house facility. The opening 10b can be provided. The ventilator 1 of the house entrance and exit 3a, side entrances 3b and 3c serves not only for adjustment of ventilation but also for adjustment of lighting, so that the location conditions of the house equipment, for example, the altitude of the calendar year of the orbiting sun, In consideration of the prevailing wind direction of the calendar year, it is preferable to determine the installation position, the size of the installation opening area, the number of installations, and the like for the wife surface 3a and the side surfaces 3b and 3c of the ventilation device 1. In addition, this house facility is a wide-range facility including not only a greenhouse but also a greenhouse.

If ventilator 1 is explained using Drawings 2, 3, 5, and 7, ventilator 1 can be installed arbitrarily on the end face, side, and roof of the house equipment for cultivation. The ventilator 1 provided on the wife's face of the house facility can also serve as an entrance / exit of the house (3a). Also, there are two types of ventilators 1 provided on the side of the house facility. One is a full opening between the pillars on the side of the house (3b). In addition, the ventilator 1 can have a large capacity for daylighting and ventilation. The other is the ventilator 1 (3c) that partially opens between the pillars described above, allowing people to enter and exit and small luggage to be carried in, and also to easily maintain the side strength against the wind and rain of the house facilities. Moreover, there are two methods for opening and closing the ventilation device 1 provided on the roof of the house facility 1, and one is a slide type in which the movable roof 12 that opens and closes the opening 10b moves as it is (FIG. 2). The other is a bellows type (FIG. 3) in which the movable roof 12 that opens and closes the opening 10b is folded and opened. The bellows type has a feature that the opening 10b can be made larger than the slide type. Further, an insect repellent net 2b is stretched outside the movable roof 12 of the opening 10b in order to prevent insects and birds from entering the house facility.

  Moreover, the ventilation apparatus 1 provided in the roof is demonstrated using FIG. FIG. 1 shows a ventilation device 1 for a roof, a wife surface, and a side surface, and the roof ventilation device 1 shows a half of the insect-proof net 2b. The roof of the house facility includes a fixed roof 10a and a movable roof 12 that opens and closes the opening 10b. The fixed roof 10a and the movable roof 12 are covered with a covering material connected to the fixed beam 11a and the movable beam 13a, respectively, to form a roof. The fixed beams 11a that support the fixed roof 10a are continuously provided in the transverse direction at intervals in the axial direction of the house equipment. The movable roof 12 is suspended from a round pipe 11b fixed to the three fixed beams 11a and is slidable in the axial direction of the round pipe 11b.

  The round pipe 11b has a groove-shaped opening 10b on the lower surface (movable beam side), and the movable beam 13a is provided with a fixed spherical body, and this spherical body is provided with the opening 10b. And fits in the round pipe 11b. That is, the movable beam 13a slides while being suspended from the round pipe 11b. With this configuration, since the frictional force generated when the movable beam 13a is moved can be suppressed as much as possible, the opening 10b can be opened and closed manually. Further, the number of round pipes 11b and the number of spherical bodies corresponding thereto are determined by the relationship between the strength of the round pipe 11b and the load and size of the movable roof 12, and usually two to five are provided per beam. In addition, the round pipe 11b also plays a role of pulling the roof, and also plays a role of increasing the strength of the entire roof. In addition, although the facility becomes large, of course, remote operation and automatic operation can be performed by a driving device.

  The movable roof 12 shown in FIG. 2 is firmly fixed by connecting two or more movable beams 13a with a connecting beam 13b. The movable roof 12 is slid as it is without being deformed, and the opening 10b is moved to A. Open and close in the direction. Therefore, the sliding movable roof 12 has higher rigidity than that of the bellows type, so that the weight of the material can be reduced.

  Further, the movable roof 12 of FIG. 3 is folded so that two or more movable beams 13a are spaced apart from each other, so that the covering material connected to the movable beams 13a is also folded like a bellows, and the opening 10b. Opens in the B direction. On the contrary, when the movable beams 13a are expanded so as to widen the interval, the covering material is also expanded to close the opening 10b. Since the bellows type movable roof 12 is folded and opened under the fixed roof 10a, the area of the fixed roof 10a can be reduced compared to the slide type, and a very large opening 10b can be created. . Therefore, ventilation efficiency can be increased.

  If the ventilation apparatus 1 provided in the roof is used, since the roof is opened greatly, it can ventilate enough, and it is effective in lowering | hanging temperature, when the inside of a house is high temperature from cultivation suitable temperature. Furthermore, if the ventilator 1 provided on the wife surface and the side surface is opened at the same time, the low temperature air flows from the ventilator 1 provided on the wife surface and the side surface, and the hot air escapes from the roof ventilator 1. As it goes, the efficiency of ventilation becomes very good.

  Moreover, as a covering material for the roof, a plastic film, a heat ray blocking sheet, an ultraviolet blocking sheet, or the like is used. When used for the bellows type movable roof 12, it is necessary to have flexibility in particular. Moreover, since the covering material for the roof is divided for each of the fixed roof 10a and the movable roof 12, even if the covering material is deteriorated due to ultraviolet rays of sunlight or a difference in temperature, only the deteriorated covering material can be replaced. Thus, the maintenance cost of the house facilities can be reduced.

The ventilator 1 provided on the wife surface and the side surface will be described with reference to FIGS. 5, 7, 8, and 9. The ventilator 1 includes three rows on the mounting frame 7 provided on the upper edge portion inside each opening. The horizontal curtain rail 4 is provided in parallel to the wall surface of the house facility, and a hanging tool 5 having a plurality of rollers suspended from each horizontal curtain rail 4 and capable of transverse in the rail direction is provided. 2 is suspended. The hanging curtain 2 can be folded or moved in the transverse direction. If the hanging curtain 2 is extended in the transverse direction, the opening is covered, and if it is retracted in the transverse direction, the hanging curtain 2 opens the opening and opens. Will do. The mechanism in which the hanging curtain 2 is suspended from the curtain rail 4 and can be traversed is a simple structure, and the state in which the hanging curtain 2 is laterally expanded and the opening is closed, or the retracted state is retracted and stored in one corner. Switching work can be easily performed manually.

It is also possible to open and close the hanging curtain 2 of the ventilator 1 by moving a rope, which requires equipment costs such as a drive device, but it can be operated unattended even if there are no people on the machine side, such as remote operation and automatic operation. It is a facility that can easily be applied, and remote automatic operation from one place is easy to apply. In the case of remote operation, the selection of the ventilation device 1 (location, radix) to be adjusted from information such as the amount of solar radiation, wind direction, and wind speed for the ventilation device 1 of the house facility, selection of the type of the banner 2 of the individual ventilation device 1 and its It is also possible to centralize the opening adjustment.

Further, if the ventilator 1 uses three different types of banners 2, it is possible to select 1 or 2 from these banners 2 to cover the opening, and it is also possible to use them simultaneously. As the three types of hanging curtains 2, film curtains 2a, insect screens 2b, and cold cocoons 2c can be used. In the film curtain 2a, the sunlight can be passed and the wind and the outside air can be blocked. In addition, films having different near-ultraviolet transmission characteristics can be adopted depending on the type of film curtain 2a. If the near-ultraviolet-emphasized type, the color development of eggplant, strawberry, etc. is promoted. Since it can be controlled, it can be selected according to the purpose of use. Further, the insect net 2b can prevent the invasion of pests and harmful birds into the house facility without adversely affecting the ventilation. Moreover, when the cold tub 2c is used, light shielding can be performed simultaneously with ventilation. In the ventilating apparatus 1 according to the present invention, this kind of the hanging curtain 2 has three stages in this example. However, the hanging curtain 2 can be installed in an overlapping manner from a single stage to a plurality of stages from the outside to the inside. Therefore, the number of stages can be selected at the time of installation, and the number of stages of the banner 2 to be used can be changed even after the installation, so that the equipment has a large degree of freedom in selection according to the application.

In addition, a high voltage line is knitted into the insect net 2b and a high voltage is applied to prevent pests and birds from entering the house equipment. Further, it is possible to emit ultrasonic waves from the ultrasonic generator to the hanging curtain 2 and thereby prevent access to harmful pests such as pests, pests and rats.

  This ventilation apparatus 1 can be applied to either a greenhouse or a greenhouse as a cultivation house facility. Moreover, this ventilation apparatus 1 is easy to optimize by adjusting the illuminance, temperature, humidity, and atmospheric components in the house equipment for cultivation, and can cultivate cultivated plants in a near-optimal cultivation environment, such as preventing pests and harmful birds from eating damage. be able to.

  The light collected in the cultivation house facilities serves as photosynthesis energy necessary for the growth of cultivated plants, and is further related to photoperiodic reactions such as flower bud differentiation. In general, the stronger the light for photosynthesis, the better, but in the winter the solar radiation is as weak as about 40% of the summer, and the light in the facility is further attenuated by the covering material. It is possible to increase the permeability by removing and cleaning the covering material of the greenhouse, but in practice it is troublesome and almost impossible. Since the banner 2 of the present apparatus 1 can be easily removed and attached, maintenance / repair for maintaining the properties such as maintaining the permeability of the banner 2 can be easily and reliably performed because the removal is effective. Moreover, it is easy to implement shade cultivation which is a short-day treatment as light adjustment for day length reaction.

  Moreover, since the optimal growth temperature of many cultivated plants is about 15-30 degreeC, it is necessary to manage the temperature in house equipment according to growth temperature. During the day, heat is accumulated in the facility due to solar heat and the temperature rises, so the room temperature is adjusted by ventilation. According to the ventilation device 1 of the present invention, the management work to be adjusted is simple and easy, the opening area can be increased, and the effects of lighting, ventilation, etc. are great. Moreover, even when the amount of carbon dioxide required for photosynthesis is insufficient in the facility in the morning of winter, the ventilation device 1 is easy to implement and easy to adjust. In addition, when using pesticides in house facilities, if this ventilation device 1 is used, the entire facility can be evenly ventilated, and the health management of pesticide sprayers can be carried out sufficiently. Residual pesticides in the atmosphere are easy to reduce.

In addition to being widely applied in the planting field, there are elements that can be widely used in the agricultural field.
