Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention mainly relates to a stirrer for agriculture and the like installed in a house.

[0002]

[Prior art]

 Conventionally, as a stirring fan for a house or the like, there is a configuration in which a fan and a cart for the fan are provided on a stirring fan main body (frame). This method of using a stirrer fan for a house, for example, is installed in the direction of the ridge of the house and blows it as far as possible toward the ridge, or it is suspended on the ceiling of the house and the wind is blown off. A method of lowering in a diffused manner is employed.

[0005] However, various measures have been taken because the reach or diffusion range of the wind is not sufficient. Among them, the following inventions can be cited as documents relating to the reach of the wind aimed at by the present invention. Japanese Patent Application Laid-Open No. Hei 10-37896 discloses an electric blower, which includes an air guide arranged on the outer periphery of an inger, a casing for covering the air guide, and a plurality of guide passages facing the outer periphery of the inger at an upper part of the air guide. Forming a return guide flow path communicating with the guide flow path, providing a return guide blade in the return guide flow path, forming a curved surface portion on a bracket facing the return guide blade, and forming a curved surface. The curved surface dimension of the section is set between the minimum dimension between the adjacent blades and the height dimension of the return guide vane. This is a configuration intended to ensure

[0004]

[Problems to be solved by the invention]

 The above document has a configuration in which spiral guide vanes (wings or return guide vanes) are provided in the guide passage on the intake side and the return guide passage on the discharge side, so that it is possible to correct the wind flow. However, it is not enough to increase the reach.

[0005] Incidentally, a configuration in which a foot 風 (cylindrical body) is provided in a stirring fan for the purpose of extending the reach distance of the wind is disclosed in literatures and the like. Is not enough.

[0006]

[Means for Solving the Problems]

 The invention of claim 1 aims at preventing disease and promoting growth by sending wind to the leaf surface boundary layer and promoting photosynthesis, or preventing disease by removing air stagnation and stuffiness while expanding the reach. Prevention, uniform growth, prevention of high-temperature damage in summer, improvement of heating effect in winter, circulation of smoke and carbon dioxide, uniform effect, etc.

[0007] The first aspect of the present invention provides a stirring fan main body, a fan provided on one side of the stirring fan main body, a cylinder provided on the other side of the stirring fan main body, and an overflow type provided in the cylinder. This is a stirrer fan for agricultural use composed of stationary blades.

[0008] The invention of claim 2 achieves the intended content of claim 1.

A second aspect of the present invention is an agitating fan for agricultural use or the like having a configuration in which the diameter of the cylindrical body of the first aspect is reduced toward the discharge side.

[0010] The invention of claim 3 achieves the intended content of claim 1.

A third aspect of the present invention is a stirrer for agricultural use or the like, wherein the stationary blade of the first aspect is provided substantially at the center of the cylindrical body in the axial direction.

[0012]

[Embodiment of the invention]

 An example of the embodiment of the present invention will be described. FIG. 8 shows the characteristics of the configuration of FIGS. As shown in the figures, it is clear from the experimental examples that the configuration examples of FIGS. 2 and 3 have excellent wind reach. In other words, the effect of the effect is exhibited by controlling the spread of the wind by the wind of 1 m / s or more so as not to rub the leaves and prevent the pain and sending a gentle wind of about 0.5 m / s to the crop.

The characteristics of the configurations of FIGS. 2 and 3 and the configurations of FIGS. 4 and 5 and the configuration of FIGS. 6 and 7 (the straight cylinder and the stationary blade of φ370) are shown in FIG. 9, as shown in FIG. Configuration examples of FIGS. 3 and 4> Configuration examples of FIGS. 4 and 5> As shown in the configuration examples of FIGS.

[0014]

【Example】

 Hereinafter, one embodiment of the present invention will be described. Reference numeral 1 denotes a stirring fan main body having a ventilation hole 1a, which is not limited to a rectangular shape in the illustrated example. On one side 1-1 (suction side) of the stirring fan main body 1, a fan 2, a cover 3, and a motor 4 are provided. In the figure, reference numeral 5 denotes a mounting arm. Further, on the other side 1-2 (blowing side) of the stirring fan main body 1, a tapered cylindrical body 6 is provided, and a stationary blade 7 is provided on the cylindrical body 6. The stationary vane 7 is located substantially at the center of the cylindrical body 6 as shown in the example of the drawing, so that the shape of the taper can be effectively used. For example, the constitutional examples of FIGS. 2 and 3 or the constitutions of FIGS. As in the example, it is possible to increase the reach of the wind and rectify the wind.

It is desirable that the ventilation hole 1a and the cylindrical body 6 be configured to have the same dimensions and eliminate resistance to help increase the reach of the wind and generate rectification of the wind.

In the figure, reference numeral 8 denotes a hermetic wind guide. This device is installed (mounted, suspended, fixed to a frame, etc.) inside, on a wall, outside, etc. of a house, building, etc., but the form of installation is arbitrary. Of course, outdoors are also possible.
