Sharing the digging machine drill bit torque dynamics technology

August 16, 2022

In order to solve the problem of short working time and long interval time of the digging machine, in order to increase the utilization rate of the machine, it is proposed to develop a multi-machine type digging machine. The sea mechanical technicians aimed at the execution structure of the 6T mini digging machine. The angular velocity sensor was used to measure the angular velocity of the boom and stick under the unloaded state of the digging machine, which verified the accuracy of the digging machine. Repeatedly analyzing the results of the forces applied to the Drill Bit under different torques at various hinge points proves:
1. When the digging machine drill moves downwards at a certain acceleration, the force of the hinge point increases with the increase of the torque.
2. When the digging machine bit decelerates downwards, the force of the hinge point decreases as the torque increases.
3. Under the same torque state, the force of the hinged joint of the digging machine decreases as the acceleration value decreases.
Finally, it is proved once again that the effect of the torque of the digging machine has a great influence on the stress of some hinge points. The force analysis results provide a basis for increasing the life of the articulation point and can be widely applied to the excavation machine actuators in the excavation equipment subjected to eccentric load and torsion.
