Description

  The present invention relates to an electrostatic nozzle device for agriculture (for spraying a house and spraying water) and an electrode structure thereof.

  Conventionally, an electrostatic nozzle device (electrostatic nozzle) employed in an unmanned control system for a house is suspended by a monorail (self-propelled transport means) that moves along a rail vertically provided in the house and the monorail. The support rod (dispersing tool) and a plurality of electrostatic nozzles provided on the support rod.

  The electrostatic nozzle device is provided with a plurality of electrostatic nozzles provided on a single support rod, and the electrostatic nozzle mounting direction is set, for example, with respect to the support rod, on one side of the electrostatic nozzle. In addition, the ejection port of the other electrostatic nozzle is provided in a relative direction (a direction orthogonal to the vertical direction of the support rod). Then, the spray ports of the electrostatic nozzles on one side and the other side are manually switched to spray the house crops or not spray the house wall. However, this manual switching operation is troublesome or has problems in operating during spraying.

  As a prior document relating to this electrostatic nozzle device, there is a “greenhouse liquid spraying device” disclosed in JP-A-7-327520 (referred to as Document 1). The present invention is characterized in that the sprinklers of each basket are arranged in a row in the ridge direction and sprayed over the entire basket, and at this time, the operation of turning off the clutch mechanism of the Gabox so as not to spray on the wall surface. Is disclosed.

  The electrostatic nozzle is composed of an umbrella-shaped recess provided in the nozzle body and a cylindrical nozzle provided at the bottom of the recess, and sprays or sprays medicine or water (referred to as a medicine). The electrostatic nozzle sprays on the farm products while ensuring a conical spray shape within a range of 45 ° up and down. However, with this cylindrical nozzle (cylindrical electrode), there is a situation where the drug in the center is not charged, so that it cannot be sprayed to every corner of this crop, and efficient spraying is not possible. There were adverse effects such as. The present inventor is also familiar with the rule of thumb and has sought a solution.

  An example of this solution is listed from the prior literature, and “Electrostatic Nozzle” disclosed in JP-A-2009-240896 is raised (referred to as Literature 2). The electrostatic nozzle of the present invention is a well-known fan-shaped nozzle part that is attached to one end of a body that can be carried by an operator and can spray a liquid in a fan shape. And a static electricity imparting portion made of a plate-like electrode plate capable of imparting static electricity to the liquid sprayed from the fan-shaped nozzle portion. By providing this static electricity imparting part movably in the fan-shaped nozzle part, for example, when increasing the spraying pressure, the electrode part is slid to the base end side by a beam, and a part of the spray particles is applied to the electrode part. It is possible to effectively avoid adhesion and dropping, and since it is possible to electrostatically impart spray particles at an optimal position at all times, a feature that enables more effective electrostatic application, or Combined with easy and reliable spraying by the fan-shaped nozzle portion, it has the feature that it can accurately spray the object up to a place where it is difficult to see from the operator.

JP-A-7-327520 JP2009-240896

  The document 1 is characterized in that, as described above, each spreader is cascaded in the ridge direction and sprayed over the entire ridges. Therefore, since the structure of the cart itself is increased in size and the power source is also powered up, there are improvements such as being uneconomical and limited installation locations. In addition, it is a structure that performs an operation of disconnecting the clutch mechanism of the Gabox attached to the end portion of the guide rail, and since it is performed manually one by one, it has trouble and requires experience.

  The document 2 has a structure in which the nozzle nozzle is simply held by two electrode portions, and the nozzle aperture and the two electrode portions are in a close positional relationship. Therefore, it is not a structure in which two electrode portions are provided at a position where the medicine from the nozzle is diffused.

  In such a structure, charging cannot be expected in a state where the entire medicine from the nozzle is diffused, so that it is difficult to charge the whole medicine. Therefore, the same adverse effects as those of the conventional electrostatic nozzle can be considered.

  And even if a plurality of electrostatic nozzles composed of the nozzle hole and the two electrode parts are provided on the support rod of the house, it is impossible to spread all over the crops, and efficient spraying is possible. Bad effects such as inability to do so are considered.

In view of the above, the present invention intends the following.
[I] The structure is such that the medicine can be automatically diffused from the injection nozzle of the electrostatic nozzle to the place where the medicine is needed, and the purpose is to reduce the amount of medicine used, reduce costs, or prevent chemical damage. .
[B] By providing a gap between the nozzle body injection port and the single-letter-shaped (elongated rectangular or plate-like) injection port of the electrode part, the diffused drug is reliably injected to the electrode part. A structure that leads to the mouth and / or two electrode plates,
[C] A structure in which the nozzle nozzle outlet and the electrode nozzle outlet are cross-shaped, and the drug is diffused and electrostatically sprayed so as to surround the crops (also on the back side of the foliage).
[D] As the structure in which the electrode part is integrated with the nozzle body of the spray nozzle with a stopper (set screw), maintenance of the net in the nozzle body is possible
[E] By providing a gap between the nozzle body nozzle and the one-letter nozzle nozzle, it is possible to avoid the generation of water and the prevention of water leakage while avoiding water dripping. Planning,
