Description

Remote Control Boat for Spraying Agricultural Chemical

The present invention relates to an apparatus for spraying medicines on rice paddies, and more particularly to a wireless coordination boat for spraying medicines for effectively spraying a medicament at a predetermined angle while moving a silk screen by adjusting it by radio.

In the munnon cultivation with water in the rice field, the herbicide, insecticide and fungicide are sprayed three to four times before and after the planting. For this purpose, the farmer takes the pesticide bottle containing the pesticide raw solution and walks around the munnon, and sprinkles the pesticide solution, which is wasted by the human hand, resulting in waste of manpower and time loss.

Japanese Unexamined Patent Application Publication No. 1997-233985 ("Method for dispersing pesticides by Bacreft on a water column") and Published Japanese Patent Application No. 10-2011-0096681 (" . The former provides a technique to load pesticides on the Hovercraft and adjusts them wirelessly to deliver the pesticide, while the latter provides the technology to load the pesticides on the boat powered by the battery and the farmer to sit on the seat and adjust and move the pesticide do.

In the former technique, the pesticide is sprayed from the spray device 11 attached to the pesticide container 10. When the spray device 11 is operated, the pesticide is sprayed from the spray nozzle arranged inside the skirt 7 below the hull. It is said that it is sprayed, and it can be understood that pesticide comes off from the bottom of hovercraft. Therefore, there is a disadvantage that the spraying area is very narrow because the pesticide is sprayed only on the lower surface of the Hoba Craft along the route of Hoba Craft, and there is also a risk of impacting the rice paddy while approaching the rice paddy to spray the pesticide near the rice paddy. On the other hand, the latter technique is disadvantageous in that the spreading time is delayed because the farmer is seated directly in the seat and moves the ship, so that it is not possible to move quickly by small power.
