The valve 10 is regulated and output to the hydraulic motor 1, thereby driving the hydraulic motor 1 to rotate.
所述激振器 2的作用是， 由液压马达 1驱动第二偏心轮 6的转轴旋转运动，通过一对 相互啮合的齿轮 15带动第一偏心轮 5的转轴转动， 从而实现第一偏心轮 5和第二偏心轮 6同步反向旋转； 两个偏心轮产生的离心力， 在转轴中心连线方向上的分量在同一时间内 相互抵消，而在转轴中心连线垂直方向的分量则相互叠加并形成激振力。该激振力通过箱 体 4传递到***头 3， ***头 3在岩石孔中振动运动并推进， 楔块形状的***头前部对岩 石产生巨大的振动***力， 将能量传递到岩石上。  The vibration exciter 2 functions to drive the rotational movement of the rotating shaft of the second eccentric 6 by the hydraulic motor 1, and rotate the rotating shaft of the first eccentric 5 by a pair of intermeshing gears 15, thereby realizing the first eccentric 5 Synchronously rotating in reverse with the second eccentric 6; the centrifugal force generated by the two eccentric wheels cancels the components in the direction of the center of the rotating shaft at the same time, and the components in the vertical direction of the connecting shaft in the center of the rotating shaft are superposed and formed Exciting force. The exciting force is transmitted to the split head 3 through the casing 4, and the split head 3 vibrates and advances in the rock hole, and the front portion of the wedge-shaped split head generates a large vibration splitting force to the rock, and transmits energy to the rock.
激振器 2采用的偏心轮组不限于一组， 也可以采用两组或两组以上的偏心轮组。 所述联接机构的主要作用是将激振器 2与挖掘机小臂 18形成联接。 激振器 2的箱体 4通过滑轮 16在导轨 14上可上下滑动， 顶部通过减振弹簧 13与机架 7相接， 这样在液 压振动岩石***机作业时， 可避免振动能量通过机架 7传递到挖掘机上。  The eccentric wheel set used in the exciter 2 is not limited to one set, and two or more sets of eccentric wheels may be used. The primary function of the coupling mechanism is to couple the exciter 2 to the excavator arm 18. The casing 4 of the exciter 2 is slidable up and down on the guide rail 14 by the pulley 16, and the top is connected to the frame 7 through the damper spring 13, so that vibration energy can be prevented from passing through the frame 7 when the hydraulic vibration rock splitter is operated. Passed to the excavator.
所述控制***的作用是，传感器 8感应被***岩石的振动反馈，将反馈信号输入微电 脑控制器 9, 微电脑控制器 9分析岩石的振动状况， 找出被***岩石的固有频率， 微电脑 控制器 9向电控液压分配阀 10输出相应的控制信号，电控液压分配阀 10调节输向液压马 达 1的流量， 从而控制激振器 2的振动频率。 The function of the control system is that the sensor 8 senses the vibration feedback of the split rock, inputs the feedback signal to the microcomputer controller 9, and the microcomputer controller 9 analyzes the vibration state of the rock to find the natural frequency of the split rock, and the microcomputer controller 9 The corresponding control signal is output to the electronically controlled hydraulic dispensing valve 10, and the electronically controlled hydraulic dispensing valve 10 regulates the transmission to the hydraulic horse. A flow rate of up to 1, thereby controlling the vibration frequency of the exciter 2.
采用上述方案后， 利用激振器产生激振力带动***头， ***头在岩石孔中推进， 其头 部契面与被***岩石接触并挤压，传感器感应岩石的振动反馈，将反馈信号输入微电脑控 制器，微电脑控制器输出相应的控制信号调节电控液压分配阀的流量，通过电控液压分配 阔的流量来控制液压马达的转速，从而控制激振器的振动频率，最终实现自动调节***头 的振动频率，使其接近被破碎岩石的固有频率，引起被破碎岩石在***头的作用下产生接 近其共振频率的振动， 产生巨大的振动***力从而轻易将岩石***破碎。  After adopting the above scheme, the excitation force is generated by the exciter to drive the split head, and the split head is propelled in the rock hole, and the head face is in contact with the split rock and squeezed, and the sensor senses the vibration feedback of the rock, and inputs the feedback signal. The microcomputer controller and the microcomputer controller output corresponding control signals to adjust the flow rate of the electronically controlled hydraulic distribution valve, and the hydraulic flow is controlled by the electronically controlled hydraulic pressure to control the rotation speed of the hydraulic motor, thereby controlling the vibration frequency of the vibration exciter, and finally realizing the automatic adjustment splitting. The vibration frequency of the head is close to the natural frequency of the broken rock, causing the broken rock to generate vibration close to its resonance frequency under the action of the splitting head, generating a huge vibrational splitting force and easily breaking and breaking the rock.
本发明不限于上述的实施方式，在不脱离本发明原理的前提下，还可以做出若干改进 和润饰， 这些改进和润饰也应该视为本发明的保护范围。  The invention is not limited to the embodiments described above, and many modifications and refinements may be made without departing from the principles of the invention, and such modifications and refinements are also considered to be within the scope of the invention.
