Abstract: To design a simple, reasonable and robust hydraulic system for self-propelled tea plucker, this paper designed the hydraulic system firstly based on analyzing the actions and operating environment of self-propelled tea Plucker, and then conducted a functional-simulation to whole system with Sim Hydraulic, including traveling simulating and plucking simulating. And also the prototype test was carried out. The system consists mainly of three subsystems: two closed travel loops, whose system pressure is 17.6 MPa, encompass separately a variable pump and a constant-displacement motor with a volumetric speed-control scheme; an open loop, whose pressure is 10 MPa, comprises a constant-displacement pump and a constant-displacement motor used for plucking. The disparity between simulating results and the design values of the system pressure was 2.78% and 0.91% respectively, the difference between test values and design values was 4.82% and 14.3%. All in all, both the simulation and the test were basically in accorded with the design, which indicates the well function of the designed hydraulic system meets well the needs of self-propelled tea plucking machine.
