A plurality of spray nozzles that spray a chemical solution onto the crops, and a high voltage generator that applies a high voltage to the chemical solution either before or after it is sprayed from the spray nozzles in order to charge the sprayed pesticide solution. It is characterized by being composed of the following.

With this configuration, the sprayed chemical liquid becomes electrically charged, so the chemical liquid flies toward the crops that are at ground potential, and the spraying of IN effectively spreads +1 over the entire crop.
You can wear it.

Hereinafter, embodiments of the present invention will be described based on the drawings.

Next, the pesticide spraying device installed on the tractor 1 will be explained. Reference numeral 4 denotes an electrically insulating chemical solution supply tank that supplies a pesticide liquid for spraying (hereinafter referred to as a chemical solution) to be sprayed onto the crops 3.The tank 4 is connected to a bonder 5 for pressure-feeding the chemical solution; 4 is an insulating support member 6 along with the bond f5.
It is installed on the tractor 1. Next, reference numeral 7 denotes a chemical liquid distribution pipe formed of a straight pipe made of metal, plastic, etc., which is connected to the pump 5 via a TFI liquid supply hose 8. is supplied to the chemical liquid distribution pipe 7 via the liquid supply hose 8. An insulating bracket 9 is attached to the chemical distribution pipe 7, and the bracket 9 is attached to a fixture 10 fixed to the tractor 1.

In order to attach the bracket 9 to the fixture 10 in a vertical or inclined state as shown in the drawings, the bracket 9 has an angle adjustment part 10 attached to the fixture 10.
A is formed. Further, the chemical liquid distribution pipe 7 has a plurality of hydraulic spray nozzles 11, 11. ...
is attached so that while the tractor 1 travels between the furrows, the chemical solution can be simultaneously sprayed on the crops 3.3 planted on both sides. And each I! The mist nozzle 11 has a head portion 11A made of metal.
The angle of the spray nozzle 11 is adjustable in order to obtain the optimum angle for the crop 3. Further, reference numeral 12 indicates a high voltage generator supplied with power from a battery (not shown), and one end of a high voltage cable 13 is connected to the high voltage generator 12. The other end is connected to a tank 4 so that a high voltage is applied to the chemical solution in the tank 4. on the other hand,
A grounding member 15 is provided on the stand 14 of the tractor l, and the grounding member 15 is configured so that υ high voltage is grounded. It is also possible to use something with sufficient ground pressure, such as wheels, or to form it with a ground chain.

The high voltage generator 12 is activated to apply a high voltage to the chemical solution in the tank 4 via the high voltage cable 13.

When the spray nozzle 11 reaches a position facing the crops 3, the nozzle 5 is driven to forcefully feed the chemical liquid in the tank 4 to the chemical liquid distribution pipe 7. The liquid pressure of the chemical solution thus pumped causes the crop 3 to be sprayed from the rIJit mist nozzle 11. Here, since the chemical solution is generally an aqueous solution obtained by diluting agricultural chemicals with water, it is a good conductor. This is no good,
The high voltage applied to the high voltage generator 12VC,l:5 is caused by the chemical liquid becoming a conductor and being conducted to the spray nozzle 11, between the head portion 11A of the spray nozzle 11 and the crop 3 at ground potential. A position difference occurs. Since a high voltage is applied to the chemical solution, I! The chemical liquid fine particles sprayed from the IJ' mist nozzle 11 are in a charged state.
