[Problems to be solved by the device]

 Damage to agricultural crops caused by birds and moles can be prevented to some extent by the above-mentioned frightening device, but pest damage cannot be prevented. The prevention of pests and diseases on crops is carried out by spraying powdered or liquid pesticides. People spray pesticides in the fields while walking through the fields using a sprayer, but such pesticide spraying requires a considerable amount of time and labor, and the fields are spread evenly and appropriately. It is difficult to spray pesticides. In addition, it is desirable to apply pesticides once a day in the morning and in the evening, but this is not possible due to the time constraints of the farmer, and the farmer sprays a large amount of pesticide at one time in an appropriate time zone. is doing. As a result, the amount of pesticides used in the fields will inevitably increase, pesticide costs will rise, and agricultural crops will become more expensive. Secondary damage to soil will increase due to pesticides, and the adverse effects on humans of pesticides attached to crops will increase. There was a problem such as doing.

The present invention has been made in view of the above problems, and is effective in preventing pests and pests of farm products and damage to harmful birds and moles, and provides a crop control device capable of easily and automatically applying pesticide. The purpose is to do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a main body having a powder storage portion surrounded by a porous cover in which desired powders such as agricultural chemicals can be scattered in minute amounts, and the main body is rotatably supported in a horizontal direction. The main body supporting means and the main body are rotatably supported by the main body, the outer end portion projects from the main body, the inner end portion is inserted into the powder storage portion, and the inner end portion is rotated to rotate the powder storage portion. A rotating shaft equipped with a stirring means for stirring the powder, and a wind turbine fixed to the outer end of the rotating shaft to rotate the rotating shaft by natural wind force and to rotate the main body in the wind direction. It is characterized by having.

As the powder stored in the powder storage portion of the main body, a pesticide for controlling pests and diseases of agricultural products, and powder of sulfur or the like that does not attract harmful birds due to odor are suitable. Further, it is desirable that the main body and the wind turbine be shaped like a model of a general harmful bird threatening device, or that at least one of the main body and the wind turbine is provided with a light reflector for bird pursuit in order to enhance the harmful bird threatening function. Yes.

Further, the main body is mounted on a pillar that is erected on the ground, and a connecting portion is provided between the pillar and the main body to generate a metallic sound for repelling moles by the rotation of the main body, and the generated metallic sound is emitted from the pillar. It is practically desirable to use it as a control device for agricultural crops that also serves as a mole mole, by transmitting it to the ground.

[0008]

[Action]

 When natural wind blows toward the main body, the windmill of the main body rotates by the wind and directs the main body in the direction of the wind, and the rotation of the rotating shaft of the windmill agitates the powder in the powder storage section of the main body. Then, the powder is actively scattered from the cover to the outside. The scattered powder rides on the wind and is distributed to the fields. If the powder is a pesticide, the pesticide will be applied automatically each time the wind blows. If the powder has a scent that is harmful to harmful birds, such as sulfur, the smell of the powder stirs in the fields every time the wind blows, and the harmful birds cannot approach.

Further, when a light reflector is attached to the main body and the main body is rotated by wind, light such as sunlight reflected by the light reflector surprises the harmful birds and drives them away. Furthermore, when a metallic sound is generated between the support of the main body supporting means by the rotation of the main body by the wind, the metallic sound is propagated through the support into the ground and drives away the moles in the ground.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. The pest control device shown in the side view of FIG. 1 and the plan view of FIG. The rotating shaft 7 and the wind turbine 9 fixed to the rotating shaft 7. The columns 6 are piles that are easily driven into any place on the ground 12 in the field.

The main body 5 is a plate-shaped weatherproof product such as a wooden product or a resin molded product, and is formed of a body part 5a and a head part 5b of the weathercock and a leg part 5c and a tail part 5d. The leg portion 5c is rotatably connected to the column 6. A circular opening 13 as shown in FIG. 3 is formed in the body portion 5a, and hemispherical covers 2 and 3 that close the opening 13 are attached to both sides of the opening 13 so that the opening 13 and the pair of covers 2 and 3 are provided. Thus, a substantially spherical powder storage portion 4 for storing the powder 1 is formed. The covers 2 and 3 are porous bodies such as metal meshes in which powder 1 such as pesticides can be scattered in minute amounts. For example, one cover 2 can be opened / closed on the side surface of the main body 5 via a hinge 14 and a simple stopper 15. And the other cover 3 is fixed to the main body 5. The openable cover 2 is opened as shown by the chain line in FIG. 2, the desired powder 1 is supplied to the powder container 4, and the cover 2 is closed. The powder 1 in the powder storage unit 4 hardly scatters from the covers 2 and 3 when the main body 5 is in a stationary state, and the main body 5 vibrates due to wind or the like, or when the rotary shaft 7 rotates as described later. When the powder 1 is agitated, a small amount of it comes out from the eyes of the covers 2 and 3 and scatters. The sizes of the eyes of the covers 2 and 3 are set so that the powder 1 is scattered in this way.

The rotating shaft 7 is a linear metal rod that rotatably penetrates through the tail portion 5d of the main body 5, the inner end portion 7a thereof passes through the center of the opening 13, and the outer end portion 7b is obliquely rearward and upward from the tail portion 5d. Extend to. For example, the rotating shaft 7 is inserted into a pipe 16 which is obliquely penetrated through the tail portion 5d and fixed, and the central portion of the rotating shaft 7 is supported by the pipe 16 so as to be rotatable and axially slidable. At the inner end 7a of the rotary shaft 7, for example, a plurality of stirring needles 8 of powder stirring means are fixed. The stirring needle 8 extends radially from the rotary shaft 7 and rotates integrally with the rotary shaft 7 to stir the powder 1. The stopper 17 is fixed to a part of the inner end portion 7a of the rotating shaft 7, and the fixed seat 9a of the wind turbine 9 is fixed to the outer end portion 7b protruding from the tail portion 5d. In normal times, the rotating shaft 7 is lowered by its own weight and is held at a position where the fixed seat 9a abuts the upper end of the pipe 16 as shown by the solid line in FIG. When the wind turbine 9 receives wind and receives an external force in the axial direction, the external force causes the rotating shaft 7 to retreat to a position where the stopper 17 comes into contact with the lower end of the pipe 16 as shown by a chain line in FIG. That is, the rotating shaft 7 retreats when the wind blows, moves forward when the wind stops, and the stirring needle 8 moves back and forth in the powder container 4 by repeating the backward movement and the forward movement, so that the powder 1 is entirely moved. It is designed to stir.

The wind turbine 9 is, for example, a propeller in which a plurality of blades 9b are extended substantially radially from a fixed seat 9a, and when the wind blows, it rotates in one direction to rotate the rotary shaft 7 to wind the main body 5 in the wind. In the direction of.

The pest control device of the above embodiment is installed in a field, and the pesticide powder 1, for example, is supplied to the powder storage unit 4 of the main body 5. When the wind blows and the windmill 9 rotates, the rotating shaft 7 and the stirring needle 8 rotate to stir the powder 1, and a minute amount of the powder 1 is discharged from the covers 2 and 3 by this stirring action, and the crops of the field are produced. Be sprinkled on. The rotation of the windmill 9 causes the main body 5 to rotate and face the direction of the wind, and the powder 1 is always sprayed rearward from the main body 5. The amount of powder 1 to be sprayed and the sprayed area in the fields are proportional to the natural wind force. Therefore, if the wind direction in the field during the pesticide application period is calculated and the installation location and the number of the pest control devices in the field are determined in advance, it is possible to easily and evenly apply the pesticide to the fields. Since this small amount of pesticide is applied by using natural wind power, it is effective in preventing pests and pests of agricultural crops in real time, and the amount of pesticide used may be smaller than usual. Is known by experiments.

When the powder 1 in the powder container 4 is not stirred by the stirring needle 8, a small amount of the powder 1 may be scattered from the covers 2 and 3 due to wind and vibration of the main body 5. However, the scattering is not stable, and the powder 1 in the powder storage unit 4 forms lumps due to moisture or the like, and the lumps can cause the covers 2 and 3 to be clogged, making it impossible to spray pesticides. is there. Therefore, if the powder 1 in the powder container 4 is agitated by the agitating needle 8 as in the above-described embodiment, the agitating needle 8 does not act to positively scatter the powder 1 from the covers 2 and 3. Moreover, the agglomeration of the powder 1 is crushed by the agitation of the agitation needle 8, the covers 2 and 3 are not clogged, and the pesticide is reliably sprayed.

The powder 1 to be sprayed is not limited to pesticides, and may be any powder that is useful for growing agricultural products, and may be, for example, powder of sulfur. In other words, the sulfur odor is a odor that harmful birds dislike, and when the sulfur powder 1 is stored in the powder storage unit 4 and sprayed as described above, the sulfur odor drifts over the entire field and the harmful bird does not approach the field. Damage to harmful birds is prevented. If the application timing of sulfur powder is different from the application timing of pesticide, one pest control device should be set with pesticide or sulfur, and if the application time of sulfur and pesticide overlaps, it will be described later. The pest control device of FIG. 5 may be used, or a plurality of pest control devices of FIG. 1 may be prepared so that sulfur and agricultural chemicals can be simultaneously sprayed.

Various modifications of the above embodiment will be described. The upper half of the covers 2 and 3 of the main body 5 may be waterproofed to prevent rainwater from entering the powder container 4. In this case, it is also preferable in appearance to cover the upper half of the covers 2 and 3 with a waterproof cover having a feather pattern of a weathercock. In addition to opening and closing one of the pair of covers 2 and 3 so as to supply the powder 1 to the powder container, for example, an opening with a lid is provided on the upper part of the covers 2 and 3, and from this opening. The powder 1 may be supplied to the powder container 4. The powder agitating means of the powder container 4 is not limited to the agitating needle 8, and for example, the inner end of the rotary shaft 7 may be bent in a meandering shape, and the powder 1 may be agitated at the bent end. Good. Further, the main body supporting means for rotatably supporting the main body 5 is not limited to the support column 6, and the main body 5 may be hung and attached to a rope stretched over the fields. In addition, if the main body 5 is attached to the support pillar 6 that is driven into the ground, the location of the pest control device can be easily moved arbitrarily, and the effect of the mole swing described below is excellent.

Next, another embodiment of the present invention will be described.

As shown in FIG. 4, the connecting portion 10 between the column 6 and the main body 5 is structured to generate a metallic sound when the main body 5 rotates. For example, a metal pipe 18 is vertically fixed on the upper surface of the column 6, a metal shaft 19 is integrally provided on the lower surface of the leg portion 5c of the main body 5, and the metal shaft 19 is slidably fitted into the metal pipe 18. .. When the main body 5 rotates with respect to the support column 6 by the wind, the metal shaft 19 and the metal pipe 18 rub against each other to generate a metallic sound. This metal sound propagates underground through props 6 to stop the activity of moles in the ground and prevent damage to crops. When a stake (not shown) is erected near the stanchion 6 and this stake and the stanchion 6 are connected with a wire, the metal sound of the stanchion 6 is transmitted from the wire to the stake and propagates underground, and the field is spread over a wider area. Damage can be prevented.

It is practically desirable to provide one pest control device with a pesticide spraying function and a mole shaving function, and to attach a light reflector to the main body 5 for the purpose of swaying harmful birds. For example, a glass ball light reflector 11 is attached to a portion of the main body 5 corresponding to the eyes of the head 5b. Further, the light reflector 11 'of the reflection tape is attached to the blade 9b of the wind turbine 9. Then, when the main body 5 is rotated by the wind, the respective light reflectors 11 and 11 'reflect the sunlight in the vicinity of the fields, which damages the harmful birds and prevent them from approaching the fields. Combining this harmful bird threat with sulfur spray will further improve the harmful bird damage prevention effect.

In the embodiment shown in FIG. 5, the powder accommodating portions 4a and 4b are provided at two positions of the main body 5, and the rotary shaft 7 is penetrated through the two powder accommodating portions 4a and 4b to accommodate each powder accommodating portion. The powder 1 stored in the portions 4a and 4b is stirred by a stirring needle 8 fixed to the rotating shaft 7. The powder 1 stored in the two powder storage portions 4a and 4b is selected from two types of pesticides, or pesticide and sulfur, and is sprayed in the fields. If two types of powders are mixed and stored in one powder storage unit 4a, the effect of the powders may be lost due to the reaction between the two types of powders. Then, the two types of powder are sprayed while maintaining their efficacy.

In the embodiment shown in FIG. 6, the main body 5 is a model of an airplane. As described above, the main body 5 can have various shapes. The main body 5 of the airplane shown in FIG. 6 is provided with a nose portion 5e and a tail portion 5f, a powder storage portion 4c is formed in the nose portion 5e, and a wind turbine 9 is fixed to the tip of a rotary shaft 7 that penetrates the nose portion 5e. It The powder container 4c shown in FIG. 6 has a cylindrical shape, and the powder 1 contained therein is agitated by the agitating needles 8 attached to the rotary shaft 7 at a plurality of positions. Further, as shown by the chain line in FIG. 6, a powder accommodating portion 4d may be provided also in the tail portion 5f, and the rotary shaft 7 may be extended to this point.

[Effect of the device]

 According to the present invention, the windmill of the main body is rotated by natural wind, and the powder in the powder container is agitated by this rotational force and is actively scattered from the cover, and the scattered powder rides on the wind. When the powder is a pesticide, the pesticide is automatically sprayed every time the wind blows, and as a result, the time and labor for pesticide spraying by farmers are reduced. At the same time, the pesticides can be sprayed effectively and the amount of pesticides used can be reduced, which is effective in lowering the cost of crops, preserving soil, and promoting agricultural evolution similar to pesticide-free agriculture. .. In addition, if the powder has a bad smell such as sulfur that the harmful birds dislike, the smell of the powder drifts in the fields every time the wind blows, preventing the harmful birds from approaching and preventing damage to the harmful birds.

Further, it is possible to easily attach a light reflector to the main body or the wind turbine, or to generate a metallic sound between the main body and the main body supporting means. It is possible to provide a multifunctional pest control device which is more effective and has a mole-stripping effect.
