摘要:
A flat and slant improvement device of an excavator is provided to level the ground and compact a slope easily. A flat and slant improvement device of an excavator comprises first and second pumps(P1,P2), a control valve(21), an arm crowd pilot line(Pac), a boom up pilot line(Pi), and a first switching valve(10). The control valve includes a boom second speed spool(3), an arm first speed spool(4), a bucket spool(6), a boom first speed spool(2), and an arm second speed spool(5). The boom second speed spool is connected with the first pump via a center parallel lilne(Ps). The bucket spool is connected with the second pump via the center parallel line. The arm crowd pilot line interconnects the arm first and second speed spools. The boom up pilot line is connected with the boom first and second speed spools. The first switch valve is switched between a first position in which the first switch valve is connected with the boom up pilot line and a second position in which the first switch valve is disconnected with the boom up pilot line.
摘要(中):
提供挖掘机的平坦且倾斜的改进装置以使地面平整并容易地压实坡度。 挖掘机的平坦且倾斜的改进装置包括第一和第二泵(P1,P2),控制阀(21),臂群控制管线(Pac),吊臂上升先导管线(Pi)和第一切换阀 (10)。 控制阀包括悬臂二速滑阀(3),臂第一速滑阀(4),铲斗滑阀(6),起重臂第一速滑阀(2)和臂二速滑阀(5)。 动臂二速滑阀通过中心平行的空气(Ps)与第一泵连接。 铲斗卷轴经由中心平行线与第二泵连接。 胳膊人群导向线将臂和第二速度线轴相互连接。 起重臂上升引导线与起重臂第一和第二速线轴连接。 第一切换阀在第一位置和第二位置之间切换,在第一位置,第一切换阀与起重臂上升先导管连接,第二切换阀与第一切换阀与起重臂上升导向管线分离。
