Vibration excitation device and engineering machinery
The invention belongs to the technical field of engineering machinery, and particularly relates to a vibration excitation device and engineering machinery. The vibration excitation device comprises a rotating assembly and a vibration excitation assembly, the first eccentric assembly is connected to the rotating assembly and comprises a plurality of fluid cavities and a plurality of movable eccentric parts, the fluid cavities and the movable eccentric parts are alternately arranged and make contact with each other, each fluid cavity communicates with the internal flow channel and is suitable for generating elastic deformation under the pressure effect of fluid, and the movable eccentric parts are suitable for rotating under the pressure effect of the fluid; and the control assembly is in communication connection with the rotating assembly and the first eccentric assembly and is suitable for controlling the rotating state of the rotating assembly and the fluid supply state so as to adjust the exciting force. According to the technical scheme, the position of the movable eccentric part can be changed by changing the fluid reserves in the different fluid cavities so as to adjust the overall eccentric state and output the exciting force, the adjusting amplitude and range are larger, impact force and noise are relatively small, and the stability of the oscillation starting stage can be improved.
本发明属于工程机械技术领域，具体涉及激振装置和工程机械。激振装置包括：转动组件，内设有内部流道；第一偏心组件，连接于转动组件上，包括多个流体腔室和多个活动偏心件，流体腔室与活动偏心件交替设置并相互接触，每个流体腔室均与内部流道连通，并适于在流体的压力作用下发生弹性形变，活动偏心件适于在流体的压力作用下转动；控制组件，与转动组件和第一偏心组件通信连接，并适于控制转动组件的转动状态以及流体供应状态，以调节激振力。通过本发明的技术方案，可以通过改变不同流体腔室内的流体储量而改变活动偏心件的位置，以调整整体偏心状态和输出激振力，调节幅度和范围更大，且冲击力和噪声相对较小，有利于提高起振阶段的稳定性。
