Hydraulic control system and screen scarifier
The invention discloses a hydraulic control system and a screen cleaning machine, and relates to the technical field of hydraulic control, the hydraulic control system is used for controlling a screen cleaning power assembly and an excavation power assembly to work, and the hydraulic control system comprises a multi-connected control valve group, a first main pump, a second main pump and a stop valve. The multi-linkage control valve group comprises a ballast raking valve linkage and an excavation valve linkage assembly, the ballast raking valve linkage is used for controlling a ballast raking power element of the screen cleaning power assembly to be opened and closed, and the excavation valve linkage assembly is used for controlling an excavation power assembly to be opened and closed; the first main pump is connected with the ballast raking valve through a first oil supply channel; the second main pump is connected with the excavation valve linkage assembly through a second oil supply channel; the stop valve is used for controlling connection and disconnection of the first oil supply channel and the second oil supply channel. The hydraulic control system solves the technical problems of low working efficiency, large energy consumption and potential safety hazards caused by current rush, weak ballast raking and many working faults of a hydraulic system during cleaning operation.
本申请公开了一种液压控制系统和清筛机，涉及液压控制技术领域，液压控制系统用于控制清筛动力组件和挖掘动力组件工作，液压控制系统包括多联控制阀组、第一主泵、第二主泵和切断阀。多联控制阀组包括扒砟阀联和挖掘阀联组件，扒砟阀联用于控制清筛动力组件的扒砟动力元件启闭，挖掘阀联组件用于控制挖掘动力组件启闭；第一主泵与扒砟阀联通过第一供油通道连接；第二主泵与挖掘阀联组件通过第二供油通道连接；切断阀用于控制第一供油通道和第二供油通道连通和切断。上述液压控制系统解决了由于清筛作业时液压系统抢流、扒砟无力、工作故障多而导致的工作效率不高、能耗偏大、存在安全隐患的技术问题。
