摘要: 本装置涉及一种推土机的改进技术,其结构是在推土机的箱体中心位置装有电液比例换向阀,在履带中间的水平连杆的前端头处装有倾斜传感器,在驾驶室内装有电控箱与操作杆,由于操作杆作用通过下面的电路控制驱动电液比例换向阀,通过油缸使推铲移动,再通过倾斜传感器进行反馈控制,使推土机整个运行过程中实行闭环控制。优点:推土机机械结构上加有电控系统,形成闭环控制,消除车体波动,推土平面平整。
英文摘要: The utility model relates to an improved technique for bulldozers, particularly a hydraulic bulldozer. The utility model has the structure that the central position of the box body of a bulldozer is provided with an electricity liquid ratio reversal valve, the frond end point of a horizontal connecting rod in the middle part of a crawler belt is provided with an inclined sensor, and the interior of a driving cab is provided with an electric cabinet and an operating rod. The electricity liquid ratio reversal valve is driven through a subjacent circuit control due to the function of the operating rod, a push shovel is moved through an oil cylinder, and the feedback control is carried out through the inclined sensor, so the bulldozer can perform the closed loop control in the whole operational process. The utility model has the advantage that the mechanical structure of the bulldozer is added with an electric control system to form the closed loop control, eliminate the body fluctuation and flatten the dozing surface.
