Benefits of technology

The motor drive rotating device includes a telescopic transmission device that can adjust the digging height and depth of a digging machine. This device includes a spline sleeve and shaft that move relative to each other in a back-and-forth motion to increase the digging depth.

Problems solved by technology

Since the driving shaft of an existing drilling and milling cutting type heading machine is arranged along the longitudinal direction of a rocker arm, in telescoping processes, a drilling and milling cutting head is liable to generate break-off damage to such transmission components as a spline shaft, a spline sleeve and the like, after being damaged, a motor or a speed reducer can only be maintained after multiple positions of the rocker arm are detached, thus resulting in large maintenance difficulty, labor consumption, time consumption and assembly difficulty, and in the maintenance and detachment processes, undamaged components are liable to be damaged, the precision of the assembly structure of the equipment is reduced, the application failure is increased and the service life of the entire machine is shortened.
The working manner of a rocker arm excavator is that the rocker arm is driven by hydraulic power to telescope and is driven by the hydraulic power to excavate materials, and a working manner of converting rotary motion into reciprocating impact motion is not used, so that the rocker arm and / or an excavating component thereof acts slowly to cause low working efficiency.
The working principles and manners of a reciprocating impact type heading machine and a drilling and milling type heading machine are different, if the structure that the driving shaft of the drilling and milling type heading machine is arranged along the longitudinal direction of the rocker arm is still used, an impact power box is liable to generate break-off damage to such transmission components as the spline shaft, the spline sleeve and the like during telescoping and / or rotary impact, moreover the manufacturing difficulty and / or mounting complexity is increased and the failure rate of the equipment is increased.
