Abstract

본 발명은 불출기의 원료 불출작업기 정량 불출작업과 과부하 방지를 수행하기 위한 것으로서, 불출된 원료 파일의 중량과 버킷 모터의 구동전류를 검출하여 과부하를 방지하면서 목표 불출량을 추종하여 일정한 양의 원료가 불출되도록 붐의 선회속도와 버킷 모터의 회전속도를 제어하는 것이다.The present invention is to perform the quantitative dispensing operation and overload prevention of the raw material dispensing machine of the dispenser, by detecting the weight of the discharged raw material pile and the driving current of the bucket motor to follow the target discharge amount while preventing overload to a certain amount of raw materials To control the turning speed of the boom and the rotational speed of the bucket motor.
