Design on Simulation Test Rig of Rock Breaking with Rolling Cutter of Mine Raise Boring Machine

In order to study the rock breaking mechanism of the rlling cuter, the rock dillillit and the rock breaking effect of the rolling cutter, a rock breaking si mulation test rig of the rolling cutter for the mine raise boring machine was researched and developed.The test rig could realize the simulation of the rock breaking proc ess under the straight-line motion of the rolling cutter, could study the tooth cutting distance of the rolling cutter, normal pressure, operation speed of the rolling cutter a s well as the different type and mode rolling cutter affected to the rock breaking effect. The rock breaking simulation test rig of the rolling cutter with the hydraulic servo system could automatically regulate the test parameters according to the program and the preset data.The high speed camera could be applied to picture the certain de tails on the rock breaking process of the rolling cutter.The actual consumed energy of the rock breaking process could be obtained with the rock cuttings screening.The visualization and the intelligent of the test process could be realized.The final test operation showed that the test ring could meet the requirements of the rock breaking test for the rolling cutter of the mine raise boring machine.
