AI Technical Summary
Technical Problem
In existing hydraulic control systems, the bucket leveling operation during boom lifting is cumbersome and requires frequent manual operation of the bucket cylinder control valve.
Method used
A hydraulic control system was designed, which connects the boom cylinder and the bucket cylinder through a flow divider valve group to automatically adjust the oil flow ratio of the bucket cylinder when the boom cylinder is lifting, thereby achieving automatic leveling of the bucket cylinder.
Benefits of technology
The bucket cylinder control valve can be automatically leveled when the boom cylinder is raised, eliminating the need for frequent manual operation of the bucket cylinder control valve, thus simplifying the operation process.

Abstract
本发明涉及液压系统技术领域，提供一种液压控制系统及作业机械。在液压控制系统中，动臂控制阀包括动臂提升位。在动臂提升位的状态下，液压泵与动臂油缸无杆腔连接，动臂油缸有杆腔通过分流阀组分别与油箱及铲斗油缸无杆腔连接。铲斗油缸有杆腔能够与油箱连接。分流阀组能控制动臂油缸有杆腔输出油液的分流比例。通过这种结构设置，在动臂油缸进行提升动作时，其有杆腔内输出的油液能够经分流阀组自动分流至铲斗油缸的无杆腔内，以驱动铲斗油缸进行自动调平动作。由此，能够基于动臂油缸的提升动作实现铲斗油缸的自动调平动作，无需人工频繁或者持续操作原有的铲斗油缸控制阀。
