Hydraulic multi-way internal inverter unit

The hydraulic multi-way internal inverter unit comprises a support, a rotating sleeve and a rotating shaft. The rotating shaft is connected with a rotating reducer of a drilling machine, therefore the rotating shaft is driven to rotate when the drilling machine works, and hydraulic oil entering from an oil inlet connector flows into multiple oil grooves through oil inlets and oil outlets in the positions with different heights. Sealing rings separate oil in every two oil grooves formed up and down, and therefore the pressure flow of the hydraulic oil among devices does not interfere mutually. The oil inlets in the rotating shaft are always communicated with the oil grooves in a guiding mode when the rotating shaft rotates, therefore the hydraulic oil enters the rotating shaft through the oil inlets and passes through support oil channels to flow into external oil outlet connectors through oil transporting holes, and oil supplying to the devices is achieved. The rotating shaft rotates but the rotating shaft is relatively fixed, and therefore pipeline winding is effectively avoided and the reliability and safety of the use of the drilling machine are improved.
