Novel shale gas drilling machine

The invention discloses a novel shale gas drilling machine which comprises bases, a derrick, a power device, transmission mechanisms, linkage devices, a rotating disc, a winch, a runner wagon, a high pressure pipeline, slush pumps and a gas control system. The power device comprises three sets of diesel engines which are connected with the slush pumps and the winch respectively through the linkage mechanisms and the transmission mechanisms, the winch is a sealed water-cooled type winch, the bases comprise the front table base and the rear table base, the winch, the rotating disc and a rotating disc transmission device are arranged on the front table base, and the power device and the linkage devices are arranged on the rear table base. The novel shale gas drilling machine has the advantages that due to the fact that the sealed water-cooled type winch is adopted, a centrifugal pump forced circulating water cooling mode is adopted for cooling roller friction hubs, and the main roller friction hub is provided with a water jacket and a water circulating pipeline; the three sets of diesel engines are adopted in the power device, the linkage mechanisms are arranged between the three sets of diesel engines, and power is enlarged; the two sets of 3NB-13000C slush pumps are arranged, and the need of jetting well drilling can be met.
