Screening bucket, working device and excavator
The invention provides a screening bucket, a working device and an excavator. The screening bucket comprises a lug plate assembly, a force bearing oil cylinder assembly, a screening bucket body, a shearing spring assembly and a double-shaft linear vibration exciter. The lug plate assembly and the screen hopper body are connected through the force bearing oil cylinder assemblies arranged on the two sides, the double-shaft linear vibration exciter is connected with the screen hopper body, the shear spring assemblies are arranged between the screen hopper body and the shear spring assemblies, and the double-shaft linear vibration exciter is used for providing a vibration source for the screen hopper body. The shearing spring assembly is used for achieving front-back staggered movement between the upper screen hopper body and the lower screen hopper body, the screening purpose is achieved, and meanwhile transmission of harmful vibration energy to the working device body structure is reduced. The energy utilization rate is high, the amplitude of the shearing motion of the spring can be adjusted by changing the excitation angular frequency so as to adapt to different screening working conditions, and the optimal screening effect is achieved. Abrasion of a pin shaft and a shaft sleeve at the front end of the working device can be effectively reduced, and vibration fatigue damage of vibration energy to structural bodies such as a connecting rod mechanism and the working device is reduced.
本发明提供一种筛分铲斗、工作装置及挖掘机；筛分铲斗，包括：耳板组件、承力油缸组件、筛斗体、剪切弹簧组件和双轴直线激振器；耳板组件和筛斗体通过若干个设于两侧的承力油缸组件连接，双轴直线激振器连接筛斗体，若干个剪切弹簧组件设于筛斗体和剪切弹簧组件之间，双轴直线激振器用于提供筛斗体的振源，剪切弹簧组件用于实现上下筛斗体之间的前后错位运动，达到筛分目的，同时减少有害振动能量向工作装置主体结构的传递。能量利用率高，可通过改变激振角频率来调节弹簧剪切运动的振幅，以适应不同的筛分工况，达到最佳筛分效果。可有效减轻工作装置前端销轴、轴套的磨损，降低振动能量对于连杆机构、工作装置等结构体的振动疲劳破坏。
