The invention belongs to the technical field of agricultural machinery, and discloses an agricultural machinery hydraulic control method which comprises a walking state hydraulic control method, and in the walking state hydraulic control method, it is determined that the agricultural machinery is in a walking state; acquiring ground resistance, and comparing the ground resistance with preset resistance; if the ground resistance is not smaller than the preset resistance, it is indicated that the ground resistance is large at the moment and possibly due to the fact that the farm tool touches stones or other obstacles, the motor is controlled to enter the high-rotating-speed mode, the hydraulic lifter is controlled to lift the farm tool, and therefore the farm machine can run normally; due to the fact that the pump is used for only providing hydraulic oil for the steering gear and the hydraulic lifter or only providing hydraulic oil for the steering gear and the hydraulic output module, in the process of controlling the hydraulic lifter to lift the farm tool, the pump does not supply oil to the hydraulic output module any more, oil flow division can be prevented, and it is guaranteed that sufficient oil enters the hydraulic lifter.
本发明属于农用机械技术领域,公开了农用机械液压控制方法,农用机械液压控制方法包括行走状态液压控制方法,行走状态液压控制方法中,确定农用机械处于行走状态;获取地面阻力,并比较地面阻力与预设阻力的大小;若地面阻力不小于预设阻力,则表明此时地面阻力较大,很可能是因为农具触碰到了石头或其它障碍物,因而控制电机进入高转速模式,并控制液压提升器提升农具,从而使农用机械能够正常行驶,此外,由于泵用于仅为转向器以及液压提升器提供液压油,或者仅为转向器以及液压输出模块提供液压油,在控制液压提升器提升农具的过程中,泵不再为液压输出模块供油,从而能够防止油液分流,以保证有充足的油液进入液压提升器。
