Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water spray air cushion boat for spraying chemicals on paddy fields.

An air cushion boat (for example, also referred to as a hovercraft) that can be remotely controlled is used for spraying a medicine to a paddy field. A drug tank is mounted on the air cushion boat, the paddy field is navigated by remote control, and the drug is sprayed from the drug tank (Patent Document 1).

Usually, for paddy fields, herbicidal treatment that suppresses germination from seeds of weeds is performed as an initial weeding period for 2-3 weeks after rice planting, and then as a mid-term weeding period, weeding that kills the germinated weeds. Processing is performed. However, the chemical spraying using the air cushion boat has a problem that it can be used only during the initial weeding period. The air cushion boat is required to have a certain size because it is equipped with a large amount of liquid chemicals to be sprayed on paddy fields and further equipped with a navigation control mechanism such as a large propeller. Therefore, during the initial weeding period, the seedlings are not large, so the navigation of the air cushion boat does not damage the seedlings, but during the mid-term weeding period, the rice to be grown is navigable by navigation. It may become an obstacle and damage the rice during navigation.

Since the air cushion boat is expensive, if it can only be used for a short period of time, it cannot be used by individual farmers.

[Embodiment 1]
FIG. 1, FIG. 2, and FIG. 3 show schematic diagrams of an ACV for drug spraying in the present embodiment. 1A and 1B are perspective views of the ACV 1 for drug spraying, where FIG. 1A shows a state before a drug bottle is mounted, and FIG. 1B shows a drug bottle 2 mounted. Further, in FIG. 2, (A) is a perspective view of the upper main body 102 of the main body 10 in the ACV1 for drug spraying, and (B) is a perspective view of the lower main body 101 and the skirt portion 20 of the main body 10 in the ACV1 for drug spraying. It is a figure. FIG. 3 is a cross-sectional view of the ACV1 for chemical spraying, which is in use in the paddy field 30.

The ACV1 for drug spraying has a main body 10 and a skirt portion 20. The main body 10 is formed of an upper main body 102 and a lower main body 101, and the upper main body 102 is a lid portion of the lower main body 101. For example, from the viewpoint of weight reduction, the main body 10 may be made of urethane foam material.

The skirt portion 20, which is also called an air cushion, is arranged around the bottom portion of the main body 10. Specifically, the skirt portion 20 extends downward from the periphery of the bottom of the lower body 101, and the area surrounded by the skirt portion 20 is a spatial area. The skirt portion 20 may further include, for example, a float on its side surface. Examples of the floating ring include urethane foam material. By providing the floating ring, the buoyancy of the ACV1 for drug spraying can be further improved.

In the drug spraying ACV1, the main body 10 includes a bottle mounting portion 11, a nozzle injection portion 14, and an injection direction control portion 15. The main body 10 may further optionally include a rotor 12 and a camera 13. The main body 10 further includes, for example, a battery 17.

A medicine bottle 2 containing a medicine is mounted on the bottle mounting portion 11 of the main body 10. The kind of the medicine stored in the medicine bottle 2 is not particularly limited, and examples thereof include a stock solution spray type flowable herbicide. INDUSTRIAL APPLICABILITY The present invention is suitable for spraying a stock solution spray type drug, for example, as described later, because the drug can be diffused into the water by nozzle injection. Further, by using the stock solution-spraying type drug as described above, for example, the capacity of the drug bottle to be mounted can be reduced, and thus the drug spraying ACV1 can also be downsized.

The shape of the bottle mounting portion 11 is not particularly limited as long as the mounted drug bottle 2 can be fixed. The size of the medicine bottle 2 that can be mounted on the bottle mounting portion 11 is not particularly limited. As described above, for example, the size of the drug bottle 2 can be set to, for example, 500 to 750 mL since the size can be reduced by using the flowable herbicide. In the case of a conventional medicine to be diluted and sprayed, for example, a medicine tank of 25 to 50 L may be mounted. Therefore, according to the present invention, the size of the medicine bottle 2 to be mounted is, for example, about 1/100. It is also possible to suppress. The bottle of the flowable herbicide usually has a capacity of 500 to 750 mL, and a single bottle can be generally sprayed on about one unit of paddy field. Therefore, according to the present invention, by mounting these bottles, it is possible to spray the chemicals assuming a paddy field area per bottle.

In the ACV1 for spraying medicine, the nozzle injection unit 14 is an injection unit that nozzle-injects the medicine in the medicine bottle 2 mounted on the bottle mounting unit 11 into the skirt portion 20. The nozzle injection part 14 is led out to the inside of the skirt part 20 and communicates directly or indirectly with the loaded medicine bottle 2 via a tube. The nozzle shape of the nozzle injection unit 14 is not particularly limited, and examples thereof include a cylinder nozzle, and a specific example thereof is a pump pressure cylinder nozzle. The tip of the nozzle of the nozzle injection unit 14 is preferably arranged, for example, with its axial direction inclined with respect to the water surface. Thereby, for example, the injection angle inside the skirt portion 20 can be controlled, the levitation navigation and the direction control can be performed by the airflow pressure in an oblique direction, and the stirring effect of the drug in the water of the paddy field can also be obtained. Is. Furthermore, since the nozzle injection unit 14 is provided, it is possible to mix and inject air and chemicals and use it as power for levitation navigation, so that it is not necessary to mount a large engine and fuel for driving the engine. is there. For this reason, the basic driving for navigation is supplemented by, for example, battery power, and it is not necessary to mount a heavy engine and fuel (for example, a mixed fuel of gasoline and engine oil), and it is possible to reduce the weight and size. is there.

When the chemical spraying ACV1 is arranged in the paddy field, the space inside the skirt portion 20 comes into contact with the water surface of the paddy field 30, as shown in FIG. Then, by spraying the drug directly onto the water surface inside the skirt portion 20 by the nozzle spraying part 14, the drug can be diffused onto the water surface. Further, by spraying the drug onto the water surface inside the skirt 20 by the nozzle spraying unit 14, the drug spraying ACV1 can be floated.

According to the ACV1 for spraying chemicals, the spraying of the chemicals is performed on the water surface inside the skirt portion 20. Therefore, for example, it is possible to suppress airborne dispersion of the chemicals and improve the herbicidal effect of the chemicals. The number of nozzle ejecting units 14 is not particularly limited, and may be one or two or more.

The chemical spraying ACV1 further includes an ejection direction control unit 15 that controls the ejection direction of the nozzle ejection unit 14. The jet direction control unit 15 can rotate the nozzle tip, change the inclination angle of the nozzle tip with respect to the water surface, and the like, for example. The injection direction control unit 15 also serves as a navigation control unit that controls the navigation of the main body 10. The ejection direction control unit 15 is, for example, a direction control servomotor. According to the servo motor, for example, as shown in FIG. 3, the nozzle tip of the nozzle injection unit 14 is rotated (direction of arrow R in FIG. 3) to change the injection direction of the medicine (direction of arrow Y in FIG. 3). You can When the ACV1 for spraying the medicine is swung, for example, the injection direction of the medicine may be changed by rotating the nozzle injection unit 14. Specifically, for example, when turning to the right, for example, the nozzle tip of the nozzle injection unit 14 is directed to the right rear direction, and when turning to the left, for example, the nozzle tip of the nozzle injection unit 14 is changed to the left rear. Turn in the direction.

The nozzle injection control unit may further include an injection pressure control unit that controls the injection pressure of the nozzle injection unit 14. The injection pressure control unit is a control unit for controlling the injection pressure of the nozzle injection unit 14, and also serves as a navigation control unit that controls the navigation of the main body 10. An example of the injection pressure control unit is the injection pump unit 18. According to the injection pressure control unit, for example, the navigation speed can be relatively promoted by relatively increasing the injection pressure, and the navigation speed can be relatively decreased by relatively reducing the injection pressure. .. When the medicine spraying ACV1 is rotated, for example, the injection pressure from the nozzle injection unit 14 is increased, the injection pump is kept rotating, and the cock valve for introducing the medicine from the medicine bottle 2 is closed. It is preferable to suspend the drug application.

The rotor 12 is a rotor that rotates in the traveling direction of the main body 10 (direction of arrow X). The rotor 12 may be arranged, for example, in front of the main body 10 or in the rear of the main body 10. However, by arranging the rotor 12 in front of the traveling direction, the paddy field to sail can be smoothed. Further, for example, it is possible to detect weeds by contacting the weeds or the like of the paddy field with the rotor 12, and it is also possible to push the weeds, suspended matter, or the like in the paddy field into the water or to squeeze the raised soil into the water. The herbicidal effect of the chemicals sprayed on the water surface can be further improved.

The shape of the rotor 12 is not particularly limited, and for example, it is preferable that the surface of the rotor 12 has spiral irregularities (also referred to as spatula shapes) extending in the axial direction.

Further, it is preferable that the rotor 12 has, for example, a right rotor and a left rotor, and the number of rotations can be controlled separately by the transmission gears. As described above, by controlling the right rotor and the left rotor separately and combining them with the control of the injection direction of the nozzle injection unit 14, for example, the swirling of the medicine spraying ACV1 can be controlled. As a specific example, when the ACV1 for spraying chemicals is turned to the left, for example, the right rotor is rotated in the forward direction (travel direction) and the rotation speed is increased, and the left rotor is moved in the backward direction. And the nozzle of the nozzle injection unit 14 is rotated to set the injection direction to the left oblique rearward direction. As a result, the ACV1 for spraying the medicine can be turned to the left. When the ACV1 for spraying chemicals is turned to the right, for example, the left rotor is rotated in the forward direction (traveling direction) and the rotation speed is increased, and the right rotor is rotated in the backward direction. The nozzle is rotated, and the nozzle of the nozzle injection unit 14 is rotated to set the injection direction to the right oblique rear direction. As a result, the ACV1 for drug spraying can be turned to the right.

The rotor 12 may further include, for example, a pressure sensor mounting portion 16 on which a pressure sensor is mounted on its support shaft. Thereby, for example, an obstacle contacting the rotor 12 can be detected during navigation. Further, when stepping down the soil raised on the water surface by the rotor 12 and winding it into water, for example, the pressure sensor (detects the pressure of vertical movement of the rotor 12) is useful because it also serves the function of increasing the rotation speed and plowing. It is also possible to use it as a trigger function (trigger).

In the medicine spraying ACV1, the camera 13 is preferably arranged above the upper main body 102 of the main body 10 so that the front of the paddy field can be confirmed, for example. The type of the camera 13 is not particularly limited, and for example, a high resolution camera for image analysis can be used. In this way, by mounting the camera 13 and performing image analysis, for example, by spraying the drug at a shallow water level where weeds easily propagate, a site where a large number of weeds propagate, and the like, the overall It is also possible to reduce the amount of drug sprayed.

The size of the ACV1 for drug spraying is not particularly limited, and for example, as shown in FIG. 4, the maximum width is preferably less than the planting width (W) of the seedling 31 in the paddy field 30, for example. With such a width, it is possible to prevent damage to the rice due to navigation even during the middle weeding period.

The navigation of the drug spraying ACV1 can be performed by, for example, a control terminal. In this case, the drug spraying ACV1 is connectable to the control terminal, for example, via a communication network, and has a reception unit that receives control data from the control terminal. The control terminal is not particularly limited, and examples thereof include a radio transmitter, a smartphone, a tablet, and the like.

The communication network is not particularly limited, and for example, a network using a known wireless communication means can be used. For example, when transmitting remote sensing data from the operation terminal to the cloud, a smartphone or the like is used as the operation terminal. A form that can be formed is preferable. Examples of the network include WiFi, LAN (Local Area Network), and the like.

The ACV1 for drug spraying can be used, for example, as follows. First, the medicine bottle 2 is mounted on the mounting portion 11 of the ACV 1 for medicine spraying. Then, in the paddy field, the nozzle sprayer 14 sprays the chemicals onto the water surface inside the skirt 20 while the chemical spraying ACV 1 is being navigated. At this time, by controlling the jetting direction from the nozzle jetting unit 14 by the jetting direction control direction 15, the navigation direction of the ACV1 for drug spraying can be controlled.

Although the present invention has been described with reference to the exemplary embodiments, the present invention is not limited to the above exemplary embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
