IV. 연구개발결과

중소형 살포기의 송풍구동시스템은 “KS 규격”에 입각 하여 기존의 방제기와 유사하게 개발하였다. 개발 순서는 송풍기(FAN), 구동시스템(노즐파이프，커버，슬라이드)，각부의 프레임을 설계 제작하였다. 제어시스템은 각각 엔진을 분리 설계하여 에너지를 절감 할 수 있도록 설계 제작하였다. 그리고 농민들이 쉽게 사용할 수 있도록 무선 리모컨으로 제어 할 수 있는 방제시스템을 제작 하였다.

- Production of optimal spraying system for energy-saving
* Design and production

II. Objectives and importance of development
1. Purpose
- The development of the energy-saving remote medium-small sized sprayer that one man could operate and evenly spray within effective distance of 70m
- Production of optimal spraying system for energy-saving
* Design and production of the fan for evenly spraying, and optimizing spraying distance
* Geometrical design and production of the spraying systems
* Production of the engine operation systems for the energy-saving
- Production of the remote controlling systems for the one-man operation
* Production of the remote functioning systems for the fast and the right time spraying
* Data base building of the sprayer operation for the auto spraying

2. Necessity of research and development
- Many commercial demands of medium-small sized sprayer that is suitable for farming field crops, pomiculture, unarranged rice paddy, slope and mountainous terrain, and cattle farms which prevent from the animal diseases such as foot-and-mouth disease and AI
* Spraying from outside of orchards and embankment of fields
* Spraying pesticides at large area in short time
* Reducing body damages from pesticides spraying
* Relieving from labor concentration situations
* Decrease from simple repetitive task
* Increase of income in farm
* Good possibility to spray the right time spraying as a mobile device
* National good competitiveness by its localization and exportation

Ⅲ. Contents of development

IV. Development
The medium-small sized sprayer with a blast drive system was developed by KS. Its development involved the integration of spraying fans, manufactured drive systems, frames, and remote controller. As engines were used separately for each system, the control system could be manufactured for energy-saving and power. A sprayer control system was controled by a remote controller for farmers to use easily.

V. Research and Utilization plan
A fundamental experiment and sprayer experiments show that developed system meets our development objective which was sprayed agricultural chemicals with effective range of 60m~70m. The developed sprayer was already finished field application and was being sold in domestic markets. The developed sprayer could be expected to utilize in agricultural farm.
