Autonomous operation device of bulldozer scarifier, and bulldozer including autonomous operation device
The invention discloses an autonomous operation device of a bulldozer scarifier, and a bulldozer including the autonomous operation device. The autonomous operation device comprises a ripping tooth, alifting oil cylinder, and an inclined oil cylinder; the lifting oil cylinder controls digging depth of the ripping tooth, and the inclined oil cylinder controls an inclination angle of the ripping tooth; when the scarifier performs operation, a control system locks an oil circuit of the lifting oil cylinder, thereby providing greater cutting force for the ripping tooth; when working stress on theripping tooth is changed, the pressure of the lifting oil cylinder is changed, a force-bearing condition of the scarifier is reflected through the change of the pressure, and a pressure sensor monitors the change of the pressure in real time; when the pressure is higher than or lower than the preset value range, the control system controls the lifting oil cylinder to lift and descend the rippingtooth, the working efficiency of the scarifier is prevented from being affected by excessive or undersized stress on the ripping tooth; and a displacement sensor detects an expansion amount of the lifting oil cylinder, the inclined oil cylinder takes an action to adjust the inclination angle of the ripping tooth so as to maintain the optimum cutting posture.
本发明公开了一种推土机松土器自主作业装置及包括该装置的推土机，包括松土齿、升降油缸、倾斜油缸等，升降油缸控制松土齿的切土深度，倾斜油缸控制松土齿的倾斜角度，当松土器进行作业时，控制系统将升降油缸的油路闭锁，从而为松土齿提供较大的切削力，当松土齿受到的工作应力发生变化时，升降油缸压力发生变化，通过该压力的变化反映松土器的受力情况，压力传感器实时监测该压力的变化，当压力大小高于或低于预设值范围时，控制系统控制通过升降油缸实现松土齿的上升和下降，避免松土齿因所受应力过大或过小而影响其工作效率，位移传感器检测升降油缸的伸缩量，倾斜油缸动作调整松土齿的倾斜角度，使其保持最有利的切削姿态。
