Forward-shovel hydraulic excavation mechanism capable of realizing horizontal shovel pushing
The invention provides a forward-shovel hydraulic excavation mechanism capable of realizing horizontal shovel pushing. The forward-shovel hydraulic excavation mechanism capable of realizing horizontalshovel pushing comprises a rack, a movable arm, a bucket rod, a shovel loader and a pair of movable arm rocking bars, wherein the lower end of the movable arm is hinged with the rack, 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 upper part of the shovel loader, the movable arm is hinged with the rack through one pairof movable arm hydraulic cylinders, one pair of movable arm rocking bars is positioned at the two sides of the movable arm, and is hinged with the movable arm, ends of one pair of movable arm rockingbars are hinged with the rack through one pair of rack connecting rods, the lower part of the shovel loader is hinged with the other ends of one pair of the movable arm rocking bars through one pairof shovel loader hydraulic cylinders, the middle part of the bucket rod is hinged with the middle part of the movable arm through one pair of bucket rod hydraulic cylinders; or the lower part of the shovel loader is hinged with the middle part of the movable arm through one pair of the shovel loader hydraulic cylinders; and the middle part of the bucket rod is hinged with the other ends of one pair of the movable arm rocking bars through a pair of bucket rod hydraulic cylinders. According to the technical scheme adopted by the invention, the forward-shovel hydraulic excavation mechanism capable of realizing horizontal shovel pushing has the beneficial effects of easy control, a great working space, great excavation force, a great bucket rod stroke, and a compact and reasonable structure.
本发明提供一种可实现水平推铲的正铲液压挖掘机构，包括机架、动臂、斗杆、铲斗及一对动臂摇杆；动臂下端与机架铰接，上端与斗杆一端铰接，斗杆另一端与铲斗上部铰接，动臂通过一对动臂液压缸与机架铰接，一对动臂摇杆对称位于动臂两侧，与动臂铰接，一对动臂摇杆一端通过一对机架连杆与机架铰接，铲斗下部通过一对铲斗液压缸与一对动臂摇杆另一端铰接，斗杆中部通过一对斗杆液压缸与动臂中部铰接；或，铲斗下部通过一对铲斗液压缸与动臂中部铰接，斗杆中部通过一对斗杆液压缸与一对动臂摇杆另一端铰接。本发明提出的技术方案的有益效果是：易于控制、工作空间大、挖掘力大、斗杆行程大、结构紧凑合理。
