Is a side simplified schematic diagram showing an example of.

  Next, the best mode for carrying out the invention will be described. In FIG. 1, a substantially direct type blower fan 20 (details will be described later, hereinafter referred to as a blower fan 20) is also built on the inverted layer X (warm air) above the building pillar 1 erected on the field A. One or a plurality of substantially horizontal blower fans 2 (details will be described later; hereinafter referred to as blower fan 2) are provided below or in the vicinity of the inversion layer X in the center of the pillar 1. As will be described later, the blower fan 2 can be adjusted in depression angle, and in some cases, can be swung in the horizontal direction. And in this example, it is a triangle shape (one example, one character shape of the illustrated example [see FIG. 4, FIG. 5, FIG. 7, FIG. 8], uneven shape of an example not shown, inverted triangle shape, square shape, etc.) The blower fan 2 is installed in the fan, and a predetermined depression angle and / or swinging is used. Desirably, the air is converged into a substantially bundled shape. The air blowing direction by the blower fan 2 may be three directions to many directions at substantially equal angles with the blower fan 2 as a base point in the state in plan view of FIG. 2 (one direction may be depending on the blower fan 2 and / or topography). ) Substantially uniformly and continuously, so that substantially the entire field A is wrapped. By securing the air to be wrapped, a film is formed by the air curtain B in the substantially horizontal direction as shown in FIG. Therefore, in the situation of frost, geothermal G (geothermal) and / or tea fruit heat (hereinafter referred to as geothermal G) is taken away, so-called radiation heat radiation (radiation of geothermal G and / or tea tree heat). By wrapping in the substantially horizontal air curtain B, this radiation cooling is avoided and heat radiation is eliminated. By eliminating this heat dissipation, for example, the damage of frost on crop H (tea, fruit, crops, fruits) is eliminated, and the dissipation of geothermal G (to ensure geothermal conditions) and / or frost By avoiding (securing the defrosting effect), it is possible to secure the growth environment (biological temperature) of the crop H (tea tree shown) and / or to secure the quality of the crop H that can effectively cope with the external conditions. Further, there are practical benefits such as protection of the global environment and generation of a substantially horizontal air curtain B slightly above the crop H growing in the field A, thereby avoiding low temperatures in the vicinity of the crop H. . And, as will be described later, by forming the air curtain B in the substantially horizontal direction in the direction of the flow of the airflow C in the field A (referred to as the flow of the airflow C), the aforementioned heat dissipation is considered to be substantially zero. In addition, by avoiding this heat dissipation, securing of the above-described effects, utilization of geothermal heat, improvement in versatility of the blowing method, and the like can be expected.

  The use of the blower fan 2 will be described with reference to FIG. 3. The geothermal heat G rises in the direction of the arrow “I” from the ground GL. This rising geothermal G can be wrapped through a substantially horizontal air curtain B generated above the crop H, so that the geothermal G can be used effectively and the various effects described above can be exhibited. In particular, by sending warm air in the flow direction of the airflow C, excellent effects can be exhibited and energy saving can be ensured as described above.

  Subsequently, the configuration in which the flow of the air curtain B in the substantially horizontal direction and the flow of the air blow fan 20 of the substantially direct type installed in the inversion layer X above the building pillar 1 are used in combination with this FIG. 3. Then, the flow of the air curtain B in the substantially horizontal direction is blown to the lower side and / or the vicinity of the building pillar 1 by the substantially direct type blower fan 20 (arrows “B” and “B ′”). As shown, a substantially vertical air curtain B1 is generated through the lower air flow. The substantially vertical air curtain B1 merges with the substantially horizontal air curtain B to form an integrated air curtain B1 ′ that wraps substantially the entire field A, and prevents cold air from entering the field A. It has features such as prevention of invasion of pests and harmful animals, etc., and improvement of cultivation efficiency, or prevention of invasion of chemicals, and establishment of pesticide-free cultivation. And as shown in this figure, as an example, when the warm air of the inversion layer X is used, it is useful for the protection of the geothermal G and / or the invasion of cold air. Even under the condition where the inversion layer X is not present, the above-described features can be partially achieved. Further, the substantially vertical air curtain B1 attracts the air curtain B in the substantially horizontal direction (guidance [indicated by an arrow “c”]), and further air blown to the far side and converged air blow can be achieved. As a result, the above-mentioned effects can be reliably achieved and expanded.

  Further, in the state of FIG. 3 illustrating an example in which the flow of the substantially horizontal air curtain B and / or the substantially vertical air curtain B1 is formed in the flow direction of the airflow C, the substantially horizontal air curtain B is illustrated. And / or the expansion of the flow of the air curtain B1 in the substantially vertical direction and the smooth flow can be ensured, and the warming of the inversion layer X can be effectively used together with the effect of avoiding the heat dissipation described above. And the effective use of warm air has great benefits such as greatly improving the above-mentioned protection of the global environment, and also reliably avoiding the low temperature in the vicinity of the crop H in the field A.

  In a situation where the blower fans 2 and 20 are installed in the field A where radiation cooling actually occurs and there is a flow of the airflow C, for example, the flow of the airflow C is substantially in the horizontal direction of the blower fan 2. A configuration in which the air curtain B and / or the blower 20 is stacked with the air blow by the air curtain B1 in a substantially vertical direction, or a configuration in which the air is efficiently mixed and a gentle wind flow is performed so as to fly. By securing (artificial ventilation), there is a feature that an effective wind flow can be secured to the crop H while protecting the crop H. Since this flow follows the flow of the airflow C, it can effectively cope with the weather and / or topographical conditions of each field A, and also controls the blowing of the blower fan 2 to ensure efficient and effective blowing. it can. The air blowing of the substantially horizontal air curtain B and / or the air curtain B1 of the substantially vertical direction is adjusted individually or for each group, or the speed, operating time, depression angle adjustment and / or neck of the warm air is adjusted. By adjusting the swing direction or the like individually or for each group, a wind flow effective for the crop H can be secured. Further, in this example, the range of the air curtain B in the substantially horizontal direction and / or the air curtain B1 in the substantially vertical direction is considerably widened by flowing the wind of the blower fan 2 and / or the blower fan 20 in a flowing manner. It is possible to reduce the number of overlapping portions (hereinafter the same), and avoid the efficient radiation cooling and the various effects described above.

  Although not shown, it is ideal to provide the blower fan 2 in the above-described air. However, if the blower fan 2 is above the crop H in the field A, the above-described effect of avoiding heat dissipation is possible and can be employed. Further, although not shown, the location and / or number of the blower fans 2 are not particularly limited when the effect of the substantially horizontal air curtain B can be expected.

  Then, a first example of the blower fan 2 shown in FIGS. 4 and 5 and a second example shown in FIG. 6 will be described. First, in the first example, the blower fan 2 is provided with a cylindrical casing 200, a rectifying plate 201 made of a net, a rectifying body, and the like, and a support body (not shown). It comprises a fan 202 for blowing air and a motor 203 for driving the fan 202. Then, the motor 203 is fixed to the building pillar 1 through the base 3, the gantry 4, and the cylinder 5. The casing 200 is supported via an arm 204 provided on the motor 203. Therefore, when the fan 202 rotates through the rotation of the output shaft 203 a provided in the motor 203, a warm air wind (wind) is generated and the wind is rectified by the rectifying plate 201. The rectified wind is blown out from the end of the casing 200 as a substantially beam-shaped (cylindrical) wind. The so-called substantially beam shape shown in FIG. 2 is characterized in that warm air is blown substantially linearly and far away. The rectifying plate 201 can increase the rectifying effect and / or reach distance, establish safety, prevent entry of small birds, and serve as a substitute for a guard.

  Note that the blower fan 2 can be adjusted at a depression angle and can be swung through a depression angle adjustment mechanism and / or a swing mechanism provided on the gantry 4. And it is possible to respond to topography, weather (climate) conditions, etc. using these mechanisms, or even if there is a change in these topography, weather (climate) conditions, etc., follow this change, There are features such as protection of the field A and / or the crop H. Further, in this example, the blower fan 2 is installed in a single character shape, but is an example, and as described above, various correspondences are possible. For example, each state of the field A, the crop H, the growth, the growth environment, etc. It is appropriately selected and / or changed depending on conditions such as the form of the field A and the weather, and in any case, it is determined based on the optimum conditions.

  Next, a second example will be described. The blower fan 2 includes a motor 203 and a blower fan 202 supported on an output shaft 203a of the motor 203. The blower fan 2 is provided on the gantry 4 (same as the first example). Also in this example, the warm air is blown substantially linearly and far away by the rotation of the fan 202. The second example is the same as the first example, and is functionally inferior. In addition, the other structure and / or characteristic in this example are based on the above-mentioned 1st example.

  Further, the substantially direct type blower fan 20 may have substantially the same structure as the blower fan 2 described above, or a simple configuration of the motor 2003 illustrated and the fan 2002 provided on the output shaft 2003a of the motor 2003 is possible. The rotation of the fan 2002 is horizontally installed in the illustrated example, and as described above, the air is blown by the air curtain B1 in the substantially vertical direction indicated by the arrows “B” and “B ′”. The movement of the blower fan 20 conforms to the above example.

  FIGS. 7 and 8 show an example in which the blower fan 2 of FIGS. 1 to 3 described above is formed in a single character, and the configuration and / or characteristics of this blower fan are similar to the above-described example.

  In addition, as shown in FIGS. 1, 2, 7, and 8, the substantially horizontal air curtain B and the substantially vertical air curtain B1 are configured to prevent the above-described intrusion prevention and wind flow. Protecting and / or guiding the air, ensuring that it is possible to secure a ceiling-type cover by enclosing the air curtain B in a wide area and a wide range of substantially horizontal directions, ensuring a defrosting effect, and expecting the above-mentioned effects There are features such as. Further, as shown in FIGS. 1 and 8, it is needless to say that the field A under the airflow C can be protected.

  Furthermore, FIGS. 9-11 is the structure which prevents the heat release etc. of the geothermal field of the field A which made the structure which provides the ventilation fan 2 in the inversion layer X, and / or tea tree heat with the air curtain B2 of a substantially horizontal / inclination direction. . The effect of the substantially horizontal / inclined air curtain B2 is similar to that of the above-described substantially horizontal air curtain B, but part of the effect is also similar to the substantially vertical air curtain B1.
