Face shovel excavation mechanism for increasing horizontal pushing driving force of bucket and lifting power of movable arm
The invention provides a face shovel excavation mechanism for increasing horizontal pushing driving force of a bucket and lifting power of a movable arm. The face shovel excavation mechanism comprisesa rack, the movable arm, the bucket rod and a terminal execution mechanism; the lower end of the movable arm is hinged on the rack and the upper end of the movable arm is hinged with one end of the bucket rod; the other end of the bucket rod is hinged with the terminal execution mechanism; the front end of the rack is hinged with each of a rack connection rod and two bucket rod hydraulic cylinders; the rack connection rod is hinged with each of a movable arm connection rod and a terminal execution mechanism hydraulic cylinder; the upper end of the movable arm connection rod is hinged with themovable arm; the front end of the terminal execution mechanism hydraulic cylinder is hinged with the terminal execution mechanism; the front end of each of the bucket rod hydraulic cylinder is hingedwith the bucket rod; the movable arm hydraulic cylinder is hinged on the movable arm connection rod; and the upper end of the movable arm hydraulic cylinder is hinged with the movable arm. The face shovel excavation mechanism has the beneficial effects of being simple and compact in structure, easy to coordinate the work of each hydraulic cylinder, large in the horizontal pushing driving force ofthe bucket and the lifting power of the movable arm, high in operation efficiency and low in energy consumption.
本发明提供一种增大铲斗平推驱动力和动臂提升力的正铲挖掘机构，包括机架、动臂、斗杆和终端执行机构，所述动臂下端铰接于所述机架上，上端铰接于所述斗杆一端，所述斗杆另一端铰接所述终端执行机构；所述机架前端分别铰接机架连杆和两斗杆液压缸，所述机架连杆上还分别铰接动臂连杆和终端执行机构液压缸，所述动臂连杆上端铰接所述动臂，所述终端执行机构液压缸前端铰接所述终端执行机构，每一所述斗杆液压缸前端铰接所述斗杆，所述动臂连杆上铰接动臂液压缸，该动臂液压缸上端铰接所述动臂。本发明的有益效果：结构简单紧凑，各液压缸工作易于协调，铲斗平推驱动力和动臂提升力大，作业效率高，能耗低。
