悬挂犁耕机组耕深自动控制的研究

悬挂犁耕深的自动控制是农机自动化的重要内容之一.为此,以黄海-304拖拉机悬挂三铧犁耕机组为研究对象,用电液比例方向阀替代主控制阀,结合应用传感器检测技术,采用闭环控制的方式来实现悬挂犁耕机组耕深的阻力控制、位置控制、力位综合控制;采用按钮式控制面板代替原有拖拉机复杂的操纵机构,使得对液压系统的操作简单准确,实现了悬挂犁耕机组耕深的自动控制.

Design of the Automatic Control of the Plowing Depth of the Integrated Plowing Set

The automatic control of plowing depth of integrated plow is one of the important aspects of agricultural machinery automation. This paper takes the Huanghai-304 tractor-plowing set as example, applying the electro hydraulic proportion valve to replace the traditional hydraulic system as well as the sensor detection technology to collect real-time operating information, the closed loop control of hitch system which performs the plough resistance and position controlling is realized; and a control panel with touch button is adopted to alternate the complicated operating mechanism, therefore, the operation of tractor is easy and accurate, and the automatic control is reached.
