Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a miniature two-way hydraulic control system. Background technique [0002] Harvesters and plowing machines are commonly used in existing hilly areas for harvesting, plowing, and marching. During operation, the stability is not high, and failures are prone to occur, especially when the agricultural machinery is reversing and harvesting, the pressure of the hydraulic equipment is not easy to control, and it will also cause the hydraulic equipment to be easily damaged, and the steering, lifting and harvesting operations are difficult. Contents of the invention [0003] The purpose of the present invention is to provide a miniature two-way hydraulic control system with high stability and more comfortable operation, which is convenient for steering and lifting of agricultural machinery for harvesting. [0004] The above-mentioned technical purpose of the present invent...
