Description

농작업기의 승강제어장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 관한 땅갈이용 농작업기의 한 예의 측며도, 제2도는 유압장치의 제어기구를 나타낸 블럭도

Claims (1)

  1. 유압식 승강장치를 개재하여 쟁기 등의 작업기를 트랙터로 장착하고, 드래프트센서에 의하여 검출되는 견인저항의 증감에 따라서 미리 경심설정기로 설정되어 있는 경심으로 되도록 작업기를 승강하는 드래프트 제어를 하는 농작업기의 승강제어장치에 있어서, 작업기 승강장치가 상승위치에서 하강쪽으로 전환되었을때, 소정의 단시간 또는 단거리만 드래프트 제어기능을 정지하여 작업기를 급강하시키는 보습 삽입제어기능을 부가함과 동시에, 전술한 드래프트센서의 검출값과 경심설정기에 의한 설정값의 관계가 작업기를 강하시키는 측으로 되어 있지 않을때는 등 급강하를 하지 않도록 한 것을 특징으로 하는 농작업기의 승강 제어장치
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임
