The present invention relates to a hydraulic apparatus of an agricultural vehicle, which comprises a hydraulic flow path and an oil tank storing operating oil supplied to the hydraulic flow path, and which further comprises: a hydraulic pump which pressurizes the operating oil and supplies the pressurized operating oil to the hydraulic flow path; an oil supply pipeline which is placed on the hydraulic flow path and connects the hydraulic pump to the oil tank; an oil recovery pipeline which is placed on the hydraulic flow path, and has one end connected to the oil tank to guide the operating oil circulated through the oil supply pipeline to the oil storage tank; and an air drain pipeline which has one end connected to the oil supply pipeline and the other end connected to the oil recovery pipeline to guide air contained in the operating oil flowing through the oil supply pipe to the oil recovery pipeline. The air in the operating oil flowing through the oil supply pipeline is recovered to the oil tank through the air drain pipeline, and only the operating oil excluding the air is introduced into a working machine or a steering unit, thereby ensuring perfect power transmission and preventing the occurrence of noise and vibration.

    본 발명은 농업용 작업차량의 유압장치에 관한 것으로, 유압 유로 및 유압 유로에 공급되는 작동유를 저장하는 오일탱크를 포함하고, 작동유를 가압하여 유압 유로에 공급하는 유압 펌프, 유압 유로 상에 배치되고 오일탱크와 유압 펌프를 연결하는 오일공급배관, 유압 유로 상에 배치되고 일 단이 오일탱크에 연결되고 오일공급배관을 통해 순환한 작동유를 오일저장탱크로 안내하는 오일회수배관, 일 단이 오일공급배관에 연결되고 타 단이 오일회수배관에 연결되고 오일공급배관을 유동하는 작동유에 함유된 공기를 오일회수배관으로 안내하는 에어 드레인 배관을 포함하여, 오일공급배관을 유동하는 작동유 중 공기는 에어 드레인 배관을 통해 오일탱크에 회수되고, 공기를 제외한 작동유 만이 작업기 또는 조향유닛으로 유입되므로, 동력을 온전히 전달할 수 있고, 소음 및 진동의 발생을 방지할 수 있는 농업용 작업차량의 유압장치에 관한 것이다.
