Self-traveling lifting fully-hydraulic coal auger

The utility model discloses a self-traveling lifting fully-hydraulic coal auger, which belongs to the technical field of design and application of a coal cutter and comprises a traveling device, a frame assembly, a lifting device, an electric control assembly, a ventilation device, a transmission device, a spiral drill frame, a hydraulic assembly and a drilling tool assembly. The traveling device is formed by a traveling crawler belt assembly, the frame assembly is formed by a crawler beam and a crawler supporting frame, and the lifting assembly is formed by a multilevel lifting oil cylinder and a supporting chain. The transmission device is formed by a driving support, a front moving box, a motor, a double-plunger pump and a driving motor, the spiral drill frame is formed by a middle frame, a lateral frame and a front frame, and the drilling tool assembly is formed by a drilling rod and a drilling head. The self-traveling lifting fully-hydraulic coal auger has the advantages of being adjustable in exploiting height of a drilling machine, achieving exploiting of an upper layer and a lower layer of thick coal seam containing waste rocks, improving utilization ratio of coal sources labor strength and working environment, saving labor cost, reducing pressure of out-of-shaft waste rocks and selection of coal and the waste rocks on the ground and transportation cost matched with out-of-shaft waste rocks and protecting environment.
