  However, many of the above-mentioned nozzles for spraying agricultural chemicals are sprayed in a generally conical shape from the nozzle, and in such a cone-shaped spray shape, when spraying on a crop, the crop is enclosed in the cone. It will be done. For this reason, the operator must check whether or not spraying can be performed on each part of the crop through the fog.

  In other words, with such nozzles, it is actually difficult to accurately perform the confirmation work while performing the spraying work when focusing on spraying all the way to the crops during the work. it can. Furthermore, in order to perform accurate spraying to places that are difficult to see from the operator, it is necessary to perform another operation such as reconfirming after the conical spray is directed to other places. As a result, the worker is forced to have a certain amount of labor, particularly when the purpose is to perform accurate spraying to a place that is difficult to see from the worker.

  The present invention focuses on such problems, and provides a nozzle that can perform accurate spraying on an object up to a place where it is difficult for an operator to see without forcing the worker more than necessary. There is to do.

  In order to achieve such an object, the present invention takes the following measures. That is, the electrostatic nozzle according to the present invention is attached to one end of a body that can be carried by an operator, and electrostatically imparts to a fan-shaped nozzle portion that can spray a liquid in a fan shape and a liquid sprayed from the fan-shaped nozzle portion. A static electricity imparting portion to be obtained.

  Here, the “fan nozzle” is also referred to as a flat spray nozzle capable of spraying mist in a flat plate shape. However, such a flat spray nozzle is generally referred to as a “fan nozzle” because the mist appears to be generally fan-shaped when viewed from the side when sprayed. Therefore, in this specification, for the sake of convenience, this flat spray nozzle is referred to as a “fan-shaped nozzle”.

  If it is such, since it will become easy for an operator to visually recognize a target object from the outer side of fog by performing fan-shaped spraying, the confirmation and spraying of a spray location can each be performed suitably. Moreover, since the sprayed chemical | medical agent becomes easy to adhere to a target object by providing an electric charge to fog with an electrostatic application part, it is difficult to see from an operator combined with the easy and reliable spraying by the fan-shaped nozzle part mentioned above. Accurate spraying can be performed on the object.

  And in order to operate an electrostatic provision part efficiently, the body shall have an operation part which can perform switching operation of spraying of a liquid and switching operation of electrostatic application of the sprayed liquid simultaneously.

And the operation part is located in the location which the operator in a body hold | grips . Thereby , it is also possible to quickly operate on / off of spraying and electrostatic application with only one hand carrying the body. In addition, a movable part that can perform an operation related to the switching operation by gripping the operator and a position where the operator puts his index finger when the liquid is not sprayed and is positioned on the tip side of the movable part. And a fixing portion to be obtained . With such a configuration , it becomes easier to perform spraying with one hand and turning on and off the electrostatic application.

And this invention has the shape which flattened the electrostatic provision part as the ring shape which flattened the electrode part while having the electrode part which can electrostatically apply to a liquid, and the power supply part which can supply electric power to the said electrode part It is possible to approach at a substantially equal distance from the periphery of the liquid to be sprayed to form a spray mark. In such a case, if the operation unit, which is a place to be gripped by the operator, is positioned between the fan-shaped nozzle unit and the power supply unit, the configuration is such that the burden on one-handed work in actual work is small. Can do. In particular, if the operation unit is set near the center of gravity of the electrostatic nozzle, the burden on the operator can be further reduced.

  On the other hand, as with the other nozzles, the fan-shaped nozzle also tends to have a wider spray angle as the spray pressure increases. Therefore, if the electrode part and the fan-shaped nozzle part can be moved relative to each other along the spray direction of the liquid, the electrostatic application part can be positioned at an optimum position at any spray pressure, so that it is stable. Electrostatic application can be performed.

  In particular, in order to easily realize the above-described structure, the electrode portion side can be operated, in other words, a slide portion that can move the electrode portion with respect to the sector nozzle portion along the liquid spraying direction. It is preferable to provide it.

  According to the present invention, by using the fan-shaped nozzle portion, it is possible to suitably check the spray location and spray each. Moreover, since the sprayed chemical | medical agent becomes easy to adhere to a target object by providing an electric charge to fog with an electrostatic application part, it is difficult to see from an operator combined with the easy and reliable spraying by the fan-shaped nozzle part mentioned above. It is possible to perform accurate spraying on the object.
