Description

DETAILED DESCRIPTION OF THE INVENTION This device relates to a spraying device that efficiently sprays the entire crop with a chemical f7. f: This relates to a pesticide spraying device in which pesticides are applied.

BACKGROUND ART When spraying agricultural crops with agricultural chemicals, it has been known that a pesticide spraying device is installed on a traveling vehicle such as a tractor, and a chemical solution is sprayed from a spray nozzle that is directed toward the crops.

However, as mentioned above, in the conventional chemical spraying device, the chemical liquid sprayed from the spray nozzle does not adhere to the crops and is dispersed into the atmosphere or soil. Not only does it have poor adhesion efficiency to crops, but it also has the drawback of creating areas where the chemical solution does not adhere to, such as on the backs of leaves and bushes, where it is difficult to spray the chemical solution.

The present invention has been made in order to eliminate the drawbacks of the prior art described above, and by efficiently charging the fine particles of the pesticide liquid for spraying sprayed from the spray nozzle, directionality is imparted to the flight of the fine particles of the chemical liquid, The purpose of this invention is to provide a pesticide spraying device that can efficiently apply a chemical solution to the entire crop.

In order to achieve the above-mentioned object, the pesticide spraying device according to the present invention includes a t+ri mist nozzle for spraying a layered liquid for spraying toward the opening in the insulating cylinder having one part between the tips. A charging device is provided between the spray nozzle and the opening and protrudes into the cylindrical body to charge the chemical liquid fine particles by applying a high voltage to the chemical liquid particles sprayed from the spray nozzle. The feature is that the configuration is complicated.

With this configuration, the chemical liquid fine particles sprayed from the spray nozzle are fully charged without being affected by wind, etc., so the chemical liquid flies toward the crops that are at ground potential and covers the entire crop. It can be efficiently attached.

Embodiments of the present invention will be described below based on the drawings.

, IA can guide you towards V-1. In addition, 21 in the figure is the stand 20 of the tractor 1.
The grounding member 21 is configured to ground high voltage. The shape thereof may be a boat shape, a wheel with a single pitch or a wheel having a plurality of claws on the outer periphery that can be sufficiently pressed against the ground, or a grounding chain.

The agricultural chemical spraying device according to the present invention has the above-mentioned configuration, and when spraying a chemical solution on crops, the height of the arm 7 relative to the J-1y bracket 6 is adjusted and the height of the arm 7 is adjusted to the support frame 8. The movable pipe joint 12 of the installed spray device unit 9 is bent as appropriate, and the cylindrical body 11 is adjusted according to the shape of the crop.
The circumference is adjusted so that the opening 11A has an optimal angle. Then, the engine 2 is driven to cause the tractor 1 to travel, and the high voltage generator 5 applies a high voltage to the corona bin 16BK of the charging device 16.

When the spray device unit 9 reaches the position facing the crops, the second pump 4 is driven, and the chemical solution in the tank 3 is sent through the spray nozzle 14 to the opening 11A through the hose 15.
At the same time, the motor 18 causes a fan] 9 to blow air in one direction toward the opening 11A.

In this case, the chemical liquid fine particles sprayed from the spray nozzle 14 travel inside the cylinder 11 toward the opening 11A. A charging device 16° 1G is provided between the spray nozzle 14 and the opening 11A, and high voltage and pressure are applied to the charging device 16 and the corona pins 16B of the cylindrical body. Since an ionization zone gauze is formed within the ionization zone 11, the chemical liquid fine particles are charged by anything passing through this ionization zone. In this way, the electrically charged chemical liquid particles fly along the lines of electric force formed between the bottle 16B and the ground frosted crop, and are efficiently attached to the entire crop. .

Since pesticide spraying equipment is used in fields, etc., if spray nozzle 1 sprays directly into the outside air, the flying direction of the sprayed chemical particles will not be stabilized due to the influence of wind, etc. The spray is dispersed all around, resulting in poor adhesion efficiency to the crops. However, in the agrochemical spraying device of the present invention, since the chemical solution is not directly ejected from the spray nozzle 14 into the outside air but is sprayed into the cylinder body 11, the sprayed chemical liquid particles flow inside the cylinder body 11 with oil. During heating, the battery is almost completely charged by the heating device 16 without being influenced by wind or the like. Moreover, in this way it is charged (
- The chemical liquid particles are formed between the charging device @16 and the crop.
Since the chemical particles are made to fly along the electric lines of force, the direction of flight of the chemical liquid particles is stabilized, and they not only adhere to the crops reliably, but also go around to the undersides of leaves and bushes, allowing the chemical liquid to adhere to a wide area of the crops. It turns out.

In addition, in the above-mentioned embodiment, the pesticide spraying device according to the present invention was explained as being installed on the tractor 1, but it can also be installed on other self-propelled vehicles, handcarts, etc. It may be installed on a transport means or transported manually without a transport means. 'In addition to the battery of the tractor 1, the power source for the high voltage generator surface 5 may be a generator or the like. Furthermore, the cylindrical body 11 of the spray device unit 9 may be configured to be directly installed on a transportation means such as a tractor 1,
Moreover, the movable pipe joint] 2, the holding cylinder 10, the motor 18, and the fan 19 are not necessarily provided. Furthermore, the spray nozzle 14 may be of a hydraulic atomization type, an air atomization type, a rotary atomization type, or the like.

As described in detail above, according to the agricultural chemical spraying device according to the present invention, the spray nozzle is provided in the insulating cylinder, and the charging device is installed between the core spray nozzle and the tip opening of the cylinder. Since it is configured to protrude into the body, the chemical liquid particles sprayed from the spray nozzle can be fully charged by the charging device, and the chemical liquid particles can be applied to crops at ground potential without being affected by wind, etc. The particles fly and efficiently attach to the entire crop. Therefore, the waste of the sprayed chemical solution is prevented, and the inconvenience of uneven spraying of the chemical solution to crops can be prevented.
