自走式番茄收获机调平液压系统设计

Design of Leveling Hydraulic System for Self-propelled Tomato Harvester

调平液压系统作为番茄收获机调平系统的重要组成部分,其性能的好坏不仅影响番茄收获机割台动刀和输送链的使用寿命,更关系到色选系统的分选效果。通过分析番茄收获机机身倾斜α角度时执行元件的受力情况,确定了系统的工作压力以及主要液压元器件的参数,并完成了液压元器件的选型,设计出调平液压系统原理图。通过AMESim软件仿真以及在4FZ-35型自走式番茄收获机上验证,表明该系统能够长期稳定运行,满足自走式番茄收获机调平系统的要求。

Leveling hydraulic system as an important part of the tomato harvester leveling system, its performance affects not only the service life of the header cutter and the conveyor chain, but also the effect of the color sorter system. By analyzing the force on the actuators under the condition of the tomato harvester body tilt angle is α, we determine the working pressure of the system and the parameters and types of hydraulic components to design the schematic diagram of the leveling hydraulic system. The simulation results of AMESim and the validation of the 4FZ-35 type self-propelled tomato harvester show that the system can operate continuously and stably to meet the re-quirements of leveling system self-contained tomato harvester.
