TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a drug dispersing device used for dispersing a drug such as a pest communication disruptor or an attractant.
[0002]
[Prior art]
In recent years, instead of using insecticides on farms and the like, attractants such as insect pheromones are released into the air, causing disturbance to the pests and reducing the number of eggs laid. Pest control methods have been adopted. As such a pest control method, a method is known in which a large number of insect pheromone dispensers are installed at predetermined intervals in a garden facility, and the insect pheromone is naturally released. As an insect pheromone dispenser, for example, as described in Patent Document 1 below, a plastic tube in which a sex pheromone is enclosed is used. When the insect pheromone dispenser is hung on a branch of a growing plant or a greenhouse frame, the enclosed insect pheromone penetrates through a plastic tube and is naturally released into the air.
[0003]
On the other hand, as a drug diffusion device, a fan-type drug diffusion device in which a volatile drug is forcibly diffused by a fan is also known, and is disclosed in, for example, Patent Document 2 below. In the fan-type drug diffusion device disclosed herein, a drug-impregnated body impregnated with a volatile drug is placed in a gas-permeable drug container, and air is blown from the back side of the drug container by a fan, so that the drug is directed forward. It is configured to spread.
[0004]

[Problems to be solved by the invention]
However, in the method of spontaneously dispersing a drug such as sex pheromone enclosed in a plastic tube, after installation, the agent is in a radiating state all the time, and the amount of radiation depends on temperature, weather, and the like. Drugs such as insect pheromones cannot be effective unless they are released at an optimal time or time according to the behavior pattern and environment of the pest to be controlled. Therefore, the method of spontaneous emission cannot effectively release drugs such as sex pheromone.
[0006]
In addition, the amount of medicine to be diffused has to be adjusted according to the number of dispensers to be installed, and in general, a large number of dispensers need to be installed. Furthermore, since the types and components of the medicines emitted from the dispenser are predetermined, another type of dispenser must be installed in order to control different types of pests. In addition, there is a problem that the conventional natural-emission type dispenser is not economical because it is disposable.
[0007]
On the other hand, when a conventional fan-type drug diffusion device is used, the amount of drug emission can be adjusted by the air volume, but it is not suitable when a small amount of drug such as insect pheromone is widely diffused. . Further, the medicine cannot be released in an optimal form according to the behavior pattern of the pest to be controlled and the weather. Furthermore, since the volatile container is impregnated with the volatile agent, the agent is reduced by spontaneous emission even when it is not necessary, and the use efficiency of the agent is low. In addition, since the type and components of the drug are predetermined, if the pest to be removed changes, it is necessary to perform a changeover such as replacing the drug container, which is inconvenient.
[0008]
Next, attractants such as insect pheromones are easily oxidized and deteriorated by ultraviolet rays. Therefore, in any case of the method using natural diffusion using a plastic tube and the method using a fan-type drug diffusion device, it is necessary to mix an antioxidant and a stabilizer with the drug.
[0009]
In view of the above, an object of the present invention is to propose a drug dispersing device capable of effectively dispersing a drug such as an insect pheromone.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the medicine dispersing device of the present invention includes a tank filled with a volatile medicine such as a pest communication disruptor, a discharge unit for discharging the medicine in the tank, and an environment. A sensor, and control means for controlling the ejection means based on a detection result of the environment sensor, wherein the environment sensor includes at least one of time, temperature, humidity, illuminance, wind direction, wind speed, and drug concentration. Is detected.
[0011]
In the present invention, the time, the temperature, the wind direction, and the like are detected by the environment sensor, and based on the detected time, the control unit controls the discharge unit to discharge the medicine. Therefore, in the case where an attractant such as an insect pheromone is emitted, the agent can be emitted so as to exhibit the maximum attracting effect according to the behavior pattern of the target pest. Therefore, it is possible to avoid unnecessary emission of the medicine, and to obtain the maximum effect by using the minimum amount of the medicine.
[0012]
Here, a pump or the like capable of adjusting the discharge amount can be used as the discharge unit. Instead, a structure having the same structure as the ink jet head in the ink jet printer can be used. In this case, the discharge unit generates a pressure change in the medicine storage chamber to which the medicine is supplied from the tank, a medicine discharge nozzle communicating with the medicine storage chamber, and the medicine in the medicine storage chamber. An actuator for ejecting a medicine droplet from the medicine ejection nozzle is provided.
[0013]
Next, a plurality of tanks can be used as the tank. In this case, a discharge means may be provided for each tank.
[0014]
In the case of providing a discharge means for each tank, if each tank is filled with a different type of drug or drug component, for example, when the pest to be controlled changes, the mixing ratio of the drug is changed. This can be handled by a method such as discharging a medicine from a tank different from the above.
[0015]
Further, the tank of the present invention is desirably formed of a material capable of blocking ultraviolet rays and / or oxygen. In this way, oxidation of a drug such as an insect pheromone and ultraviolet deterioration can be prevented, and it is not necessary to mix an antioxidant and a UV stabilizer in the drug.
[0016]
Next, in the present invention, the medicine ejected from the ejection means may be directly emitted into the air, but in the case of an insect pheromone or the like, the ejected medicine is received and diffused. It is desirable to have a dispersing means such as an evaporating dish.
[0017]
When a small amount of drug is diffused over a wide range or when a drug having a low diffusion coefficient (hard to diffuse) is diffused, the drug discharged from the discharge unit is received as the dispersing unit, and the natural dispersion is performed. It is desirable to use one having a configuration that includes a medicine carrying member that carries the medicine in a possible state and a transport mechanism that circulates the medicine carrying member along a predetermined transport path. In addition, according to this configuration, the work of installing a large number of drug diffusion devices is not required.
[0018]
On the other hand, when installing a plurality of drug diffusion devices, each drug diffusion device has a self-information storage unit that holds at least information on the installation location, and the control unit is held in the self-information storage unit. It is desirable to be configured to control the discharge means based on the information. For example, in a medicine dispersing device installed in a corner of a medicine dispersing place, the medicine dissipated on the upstream side flows downwind, so that the ejection amount of the medicine may be small. Conversely, in the case of windward, the ejected medicine flows downwind, so the ejection amount of the medicine needs to be larger than usual. The control unit can perform such control based on the position information held in the self information storage unit. As a result, the medicine can be uniformly diffused over the entire target area.
[0019]
Next, in order to use one or a small number of drug dispersing devices to disperse the drug in a target place or a wide range, the traveling mechanism is equipped with the drug dispersing device having the above-described configuration, and the traveling control means performs the traveling. The driving of the mechanism may be controlled. By using such a mobile medicine dispersing device, the medicine can be efficiently diffused to a wide place or the like.
[0020]
Instead of the traveling type, the medicine spraying device having the above configuration may be suspended from a balloon and floated at a medicine spraying place. Such a floating drug diffusion device can be used in a greenhouse or the like. For example, the floating drug diffusion device may be moved using a blower or the like.
[0021]
Next, when a plurality of drug diffusion devices are installed, if each drug diffusion device is centrally managed in one place, the drug can be appropriately diffused to the entire target area. To this end, the medicine dispersing system of the present invention has a plurality of medicine dispersing devices arranged at different locations, and central control means for controlling each medicine discharging operation of the medicine dispersing device, As the medicine dispersing device, the one having the above-described configuration is used, and the central control means controls the location of each medicine dispersing device, and the medicine ejection of each medicine dispersing device based on the detection result by the environment sensor of each medicine dispersing device. It is characterized in that the presence / absence and / or the medicine ejection amount is controlled.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, with reference to the drawings, each embodiment of a drug diffusion device to which the present invention is applied will be described.
[0023]
(Embodiment 1)
FIG. 1 shows a medicine dispersing device suitable for dispersing a medicine such as a communication disrupting agent or an attractant into a greenhouse or the like. FIG. 1A is a schematic configuration diagram of a medicine dispersing apparatus. The medicine dispersing apparatus 1 includes a first tank 2 filled with a volatile medicine A and a second tank 3 filled with a volatile medicine B. Have. The medicines A and B are filled in these tanks 2 and 3 in a gas or liquid state. The medicines A and B are supplied from these tanks 2 and 3 to the suction ports 6a and 6b of the pump 6 of a variable discharge amount via the medicine supply paths 4 and 5. After each medicine sucked by the pump 6 is mixed in the pump 6, the medicine is discharged from the discharge pipe 7 connected to the discharge port 6c. From the discharge pipe 7, the mixed medicine C is discharged to an evaporating dish 8 as a dispersing means. The mixed medicine C discharged to the evaporating dish 8 is naturally diffused. A heater 8a may be attached to the evaporating dish 8 to control the emission rate.
[0024]
The drive control of the pump 6 is performed by the control circuit 9. The input side of the control circuit 9 is connected to a timer 11 for measuring time, a temperature sensor 12, an illuminance sensor 13, a wind direction sensor 14, and a wind speed sensor 15. A humidity sensor 16 may be connected. Further, an external sensor 17 such as a concentration sensor for detecting a drug concentration is also connected. The control circuit 9 is composed of a microcomputer or the like, and controls the driving of the pump 6 based on the detection result from each sensor according to a control program stored in advance. That is, it controls whether or not the mixed medicine C is discharged by the pump 6 and the discharge amount. In this example, the control circuit 9 also controls the driving of the heater 8a.
[0025]
An external power supply can be used as a drive power supply for each unit. However, as shown in the figure, using a battery power source 18 such as a solar battery has the advantage that there is no restriction on the installation location.
[0026]
Next, FIG. 1B is a sectional configuration diagram showing the first tank 2. The first tank 2 of the present embodiment includes a hard case 2a made of a plastic material having ultraviolet blocking properties and a flexible medicine bag 2b built in the hard case 2a. The medicine bag 2b is formed of an oxygen-impermeable flexible material formed by laminating an aluminum vapor-deposited film on a plastic film. The other second tank 3 is similarly configured. In this example, the drug tubes constituting the drug supply paths 4 and 5 are also formed of a material capable of blocking ultraviolet rays and oxygen, and the case of the pump 6 is formed of a similar material.
[0027]
In the drug dispersing device 1 configured as described above, attractants of insect pheromone or the like are used as the drugs A and B, and are installed at predetermined intervals on a farm or the like. It is necessary to emit attractants in accordance with the communication time of the male and female of the pest to be controlled. In the present example, the control circuit 9 drives the pump 6 to discharge the medicine C based on the time measured by the clock timer 11. Therefore, since the pump 6 can be driven to discharge the medicine only during a necessary time zone, the medicine can be effectively diffused, and the mating of the pests can be effectively suppressed. In other words, unnecessary drug emission can be suppressed, so that the maximum effect can be obtained with a minimum amount of drug.
[0028]
Further, the control circuit 9 controls the driving of the pump 6 according to the temperature, wind direction, wind speed, illuminance, and the like. For example, when the temperature is high, the amount of radiation increases, so the discharge amount is reduced, and when the wind speed is high, the discharge amount is increased. By controlling the ejection amount in this way, the concentration of the drug to be diffused can be kept substantially constant.
[0029]
Further, since the medicines A and B are filled in the tanks 2 and 3 in a sealed state, the medicines do not decrease due to spontaneous emission unlike the conventional air-permeable tanks. If each of the tanks 2 and 3 is of a cartridge type, the replenishment operation when the medicine runs out can be simplified. In addition, by replacing the tank with a tank filled with a different chemical, it is possible to immediately respond to a case where the type of the target pest has changed.
[0030]
In this example, the cases of the tanks 2 and 3, the medicine supply passages 4 and 5, and the pump 6 are made of a material having an ultraviolet blocking property and an oxygen impermeable property. Therefore, it is not necessary to use an antioxidant or an ultraviolet stabilizer even in the case where the drugs A and B are easily oxidized and easily deteriorated by ultraviolet rays, for example, in the case of an attractant such as an expensive insect pheromone such as aldehyde. .
[0031]
(Embodiment 2)
FIG. 2 is a schematic configuration diagram illustrating a drug diffusion device according to the second embodiment. The medicine diffusion device 20 includes a first tank 21, a second tank 22, and a third tank 23 as medicine tanks, each of which is filled with medicines a, b, and c having different components. In addition, three pumps 6A to 6C are disposed, and each of the pumps 6A to 6C is configured to suck each of the medicines a to c through the medicine supply paths 4a to 4c and discharge the medicines from the discharge pipes 7a to 7c. From each of the discharge pipes 7a to 7c, the medicines a to c are discharged to a common evaporating dish 8. Each of the pumps 6A to 6C can be individually driven and controlled by the control circuit 9. The other configuration is the same as that of the drug diffusion device 1 shown in FIG. 1, and the description thereof is omitted.
[0032]
In the medicine dispersing device 20 having this configuration, for example, each of the tanks 21 to 23 is filled with an attractant such as an insect pheromone containing a different active ingredient. By selectively driving the pumps 6A to 6C by the control circuit 9, the required attractant can be discharged and diffused. In addition, by simultaneously driving two or more of the pumps 6A to 6C and adjusting their discharge amounts, it is possible to emit attractants having different composition ratios. Therefore, an effective attractant can be emitted to each of the different types of pests. Of course, by increasing the number of tanks, it is possible to emit an attractant that is effective against more kinds of pests.
[0033]
(Embodiment 3)
FIG. 3 shows a medicine diffusion device according to the third embodiment. FIG. 3A is a schematic configuration diagram of the drug diffusion device 30. The basic configuration is the same as that of the drug diffusion device 1 shown in FIG. Is omitted.
[0034]
The medicine emission device 30 according to the present embodiment includes a belt conveyor-type emission device instead of the evaporating dish. That is, a belt conveyor 32 around which an endless belt 31 provided with a material capable of absorbing and carrying a medicine, for example, a surface material such as felt or sponge, and a drive mechanism 33 for driving the belt conveyor 32 are included. Have. The medicine C is discharged from the discharge pipe 7 onto the endless belt 31. When the belt conveyor 32 is driven, the endless belt 31 carrying the medicine C moves along a predetermined conveyance path, and the medicine C is diffused along the conveyance path of the endless belt 31.
[0035]
Therefore, for example, as shown in FIG. 3 (b), in a site 34 such as a greenhouse or a farm, the medicine dispersing device 30 is installed at the corner and the belt conveyor 32 is routed in each direction, so that the entire site 33 can be obtained. The drug can be dissipated.
[0036]
In addition, it is of course possible to apply a belt conveyor 32 instead of the evaporating dish 8 in the medicine diffusion device 20 shown in FIG.
[0037]
(Embodiment 4)
FIG. 4 shows a drug diffusion device according to the fourth embodiment. As shown in FIG. 4 (a), the medicine dispersing device 40 according to the present embodiment includes a medicine dispersing device unit 41, a traveling mechanism 42 on which the drug dispersing device unit 41 is mounted, and a traveling control circuit 43. , A traveling position sensor 44. The medicine dispersing device unit 41 has, for example, the same configuration as that of the drug dispersing device 20 shown in FIG.
[0038]
The traveling mechanism 42 of the present example includes a pair of front and rear traveling wheels 42a, 42b traveling on a traveling rail 45, and a pedestal 42c suspended from the traveling wheels 42a, 42b. 41 is mounted in a suspended state.
[0039]
As shown in FIG. 4B, the running rail 45 extends in the longitudinal direction on the ceiling surface of the greenhouse 46. The traveling control circuit 43 controls the traveling mechanism 42 based on a signal from a traveling position sensor 44 including an encoder and the like. Thus, the hot water agent dispersing device 40 reciprocates in the greenhouse 46 at a predetermined speed along the traveling rail 45.
[0040]
By using the traveling-type medicine dispersing device 40 configured as described above, it is possible to disperse the medicine at a uniform concentration over the entire emission target area such as a greenhouse. Therefore, there is no need to install a large number of drug diffusion devices.
[0041]
Note that the drug diffusion device unit 41 may be suspended from a balloon or the like and float in a closed space such as a greenhouse. In this case, for example, the medicine diffusion device can be moved by periodically changing the wind direction in a greenhouse by a blower or the like.
[0042]
(Embodiment 5)
FIG. 5 shows a medicine diffusion device according to the fifth embodiment. FIG. 5A is a schematic configuration diagram of the drug diffusion device 50, and the basic configuration is the same as that of the drug diffusion device 1 shown in FIG. The difference is that a self-information storage unit 51 and an optimum condition storage unit 52 are provided, and the control circuit 9 controls the drive of the pump 6 based on the information held in these storage units 51 and 52. I do. The self-information storage unit 51 stores, for example, information on the installation location of the drug diffusion device 50.
[0043]
As shown in FIG. 5B, for example, the drug dispersing device 50 having this configuration is installed in a grid pattern at predetermined intervals on a site 53 such as a farm to which the drug is to be released. In this case, if the amount of medicine ejected by each medicine dispersing device 50 is the same, the medicine concentration of each part differs according to the wind direction, and the medicine cannot be uniformly diffused. For example, in the case where the wind direction is the direction indicated by the arrow in the drawing, the medicine discharged and diffused by the medicine dispersing device group 50A on the leeward side flows to the medicine dispersing device group 50B on the leeward side. Drug emission concentration increases.
[0044]
In the present example, information on the installation location is stored and held in the self-information storage unit 51 of each drug diffusion device 50. Further, the optimum condition storage unit 52 stores the optimum condition of the medicine ejection amount obtained from the combination of the wind direction and the installation location. Therefore, in the control circuit 9, based on the wind direction detected by the wind direction sensor 14 and the installation location obtained from the self-information storage unit 51, the pump is controlled so as to match the optimum condition of the medicine ejection amount obtained from the optimum condition storage unit 52. 6 is driven to discharge an optimal amount of medicine.
[0045]
In the case where the other conditions are the same, in the case of the wind direction shown in FIG. 5B, the medicine ejection amount by the medicine distribution device group 50A on the windward side is smaller than the medicine ejection amount by the medicine dispersion device group 50b on the leeward side. Will also be versatile. As a result, the medicine can be diffused at a substantially uniform concentration over the entire site 53.
[0046]
(Embodiment 6)
Next, FIG. 6A is an explanatory view showing a drug diffusion system to which the present invention is applied. The drug dispersing system 60 includes a plurality of drug dispersing devices 62 installed at predetermined intervals in a drug dispersing target site 61, and a wireless control device 63 for remotely controlling these drug dispersing devices 62 by radio. .
[0047]
FIG. 6B is a schematic configuration diagram of the drug diffusion device 62, and the basic configuration is the same as that of the drug diffusion device 1 shown in FIG. The difference is that a self-information storage unit 63 in which an installation location and an address (device ID) is stored and a transmission / reception circuit 64 are provided.
[0048]
The wireless control device 63 calculates the optimal driving condition for each drug dissipating device 62 based on the environmental parameters such as the wind direction and temperature provided from each drug dissipating device 62 and the information on the installation location and the address. This is transmitted to the radiation device 62. In each drug diffusion device 62, the control circuit 9 drives the pump 6 to discharge the drug based on the received signal. According to this configuration as well, the drug can be diffused at a uniform concentration over the entire site 61 without being affected by the wind direction or the like, as in the case of the drug diffusion device 50 shown in FIG.
[0049]
(Other embodiments)
In each of the above embodiments, a variable discharge amount type pump is used as the discharge means of the medicine. Alternatively, a medicine ejection mechanism similar to an ink jet head used in an ink jet printer or the like can be adopted. For example, the medicine ejection mechanism includes a medicine storage chamber to which a medicine is supplied from a medicine tank, a medicine ejection nozzle that communicates with the medicine storage chamber, and a medicine in the medicine storage chamber that generates a pressure change to cause a change in the medicine from the medicine ejection nozzle. An actuator that ejects a droplet of a medicine may be provided. As the actuator, an electrostatic actuator utilizing an electrostatic force generated between the opposed electrodes, a piezoelectric element, or the like can be used.
[0050]
【The invention's effect】
As described above, in the medicine dispersing device of the present invention, the medicine is ejected from the tank filled with the medicine by the ejection means such as the pump, and the environment sensor for detecting the medicine ejection amount as temperature, time zone, wind direction, and the like. Is controlled based on the
[0051]
Therefore, according to the present invention, unlike a conventional method of spontaneously dispersing a medicine, it is possible to disperse an optimal amount of medicine at a required time according to weather or the like. Therefore, it is possible to suppress the wasteful consumption of the medicine and obtain the maximum medicine emission effect with the minimum medicine consumption. In particular, the device of the present invention is suitable for use in dispersing a small amount of attractants such as insect pheromones, for example, for disturbing insect pests.
