| description | The present invention relates to an agricultural vehicle, which comprises: a storage tank which stores operating oil; a working machine line pump which is connected to the storage tank to supply the operating oil to a working machine; a working machine line which connects the working machine to the working machine line pump; a steering line pump which is connected to the storage tank to supply the operating oil to a steering unit; a steering line which connects the steering unit to the steering line pump; a drain line which has one side connected to the working machine line and the other side connected to the storage tank; a sequence valve which is provided in the drain line to selectively open and close the drain line; and a pilot line for the sequence valve, which connects the sequence valve to the steering line, and is connected to the working machine line downstream of the connection part between the drain line and the working machine line in the form of passing through the working machine line. When the working machine is not driven, the operating oil flowing through the working machine line is recovered to the storage tank via the drain line, thereby preventing the occurrence of heat and noise as the operating oil circulates through the working machine line.
본 발명은 농업용 작업차량에 관한 것으로, 작동유를 저장하는 저장탱크, 저장탱크에 연결되고 작업기에 작동유를 공급하는 작업기라인펌프, 작업기라인펌프와 작업기를 연결하는 작업기라인, 저장탱크에 연결되고 조향유닛에 작동유를 공급하는 조향라인펌프, 조향라인펌프와 조향유닛을 연결하는 조향라인, 일 측이 작업기라인에 연결되고 타 측이 저장탱크에 연결되는 드레인라인, 드레인라인에 구비되며, 드레인라인을 선택적으로 개폐하는 시퀀스밸브 및 조향라인과 시퀀스밸브를 연결하고, 작업기라인을 통과하는 형태로 드레인라인 및 작업기라인 연결부의 하류에서 작업기라인과 연결되는 시퀀스밸브용 파일럿라인을 포함하여 작업기를 구동하지 않을 경우에는 작업기라인을 유동하는 작동유를 드레인라인을 경유하여 저장탱크로 회수함으로써, 작동유가 작업기라인을 순환함에 따라 열과 소음이 발생하는 것을 차단하는 농업용 작업차량에 관한 것이다. |
