Ultrasonic vibration rock crushing experimental device and experimental method

The invention discloses an ultrasonic vibration rock crushing experimental device and experimental method. The experimental device is composed of a drilling mechanism, an ultrasonic vibration mechanism and a drilling parameter control system. A clamping device is installed on a drilling machine base, a rock is fixed on the clamping device, and two cylinders are fixed on the two sides of a drilling machine rack. A motor, a driving wheel and a driven wheel are fixed on the drilling machine rack, the lower end of a drilling machine column is fixedly connected with the drilling machine base, and the upper end of the drilling machine column is fixedly connected with the drilling machine rack. A vibration transmission rod and a faucet are connected to the upper end of a driven rod, and a drill pipe and a drill bit are connected to the lower end of the driven rod. An ultrasonic transducer and the drilling mechanism are connected together through a connecting rod mechanism. A control cabinet composed of a flow regulator, a frequency converter, a driving power supply, a pressure regulating valve and an ultrasonic generator is connected with a water pump, the motor, the cylinders and the ultrasonic transducer. By means of the ultrasonic vibration rock crushing experimental device and experimental method, the whole process of crushing the rock during comprehensive drilling and core drilling under different drilling parameters can be simulated, and rock grindability tests and evaluation of the performance and quality of a micro drill bit can also be achieved.
