Full-hydraulic crushing scarifier of excavator
The invention discloses a full-hydraulic crushing scarifier of an excavator. The scarifier comprises a scarifier shell and a tooth bucket which are movably connected, a hydraulic impactor is arranged in the scarifier shell, a first telescopic oil cylinder is connected to the top of the scarifier shell, a rotating shaft is arranged at the bottom of the first telescopic oil cylinder, and a connecting rod is arranged in the middle of the rotating shaft in a sleeving mode. The two sides of the rotating shaft are sleeved with push rods, the sides, away from the rotating shaft, of the push rods are connected with second telescopic oil cylinders through second movable nodes, and a third telescopic oil cylinder is movably connected with a bucket. The scarifier has the beneficial effects that the first telescopic oil cylinder and the hydraulic impacter are arranged, and the first telescopic oil cylinder and the hydraulic impacter work independently, so that the scarifier has the functions of crushing rocks and loosening soil at the same time. In addition, the second telescopic oil cylinder is arranged to drive the push rod to move, so that independent rock crushing and soil loosening operation is guaranteed, and the service life of the first telescopic oil cylinder and the service life of the hydraulic impactor are prolonged.
本发明公开了一种挖掘机全液压破碎松土器，该松土器包括活动连接的松土器壳体及齿斗，松土器壳体的内部设置有液压冲击器，松土器壳体的顶部连接设置有第一伸缩油缸，第一伸缩油缸的底部设置有转轴，转轴的中部套设有连接杆，转轴的两侧均套设有推杆，推杆远离转轴的一侧通过第二活动节点连接设置有第二伸缩油缸，第三伸缩油缸活动连接设置有挖斗。有益效果：通过设置第一伸缩油缸及液压冲击器，且第一伸缩油缸及液压冲击器之间独立作业，这样可以使本发明同时具有破碎岩石及松土的功能；另外，通过设置第二伸缩油缸带动推杆移动，从而保证破碎岩石及松土作业的独立进行，进而提高第一伸缩油缸及液压冲击器的使用寿命。
