Self-walking lifting full-hydraulic auger coal mining machine

The invention discloses a self-walking lifting full-hydraulic auger coal mining machine and belongs to the technical field of design and application of coal mining machine. The self-walking lifting full-hydraulic auger coal mining machine comprises a walking device, a frame assembly, a lifting device, an electric control assembly, a ventilation device, a transmission device, an auger frame, a hydraulic assembly and a drill assembly, wherein the walking device is composed of a walking crawler assembly; the frame assembly comprises a crawler beam and a crawler supporting frame assembly; the lifting device comprises a multistage lifting oil cylinder and a supporting hinge assembly; the transmission device comprises a driving frame, a front driving box, a motor, a double-plunger pump and a driving motor; the auger frame comprises a middle frame, a side frame and a front frame; the drill assembly comprises a drill rod and a drill bit. The mining machine has the advantages that the mining height of the drilling machine is adjustable; upper and lower coal layers of thick band coal layers can be mined; the utilization rate of coal resources is improved; the labour cost is saved; the labour intensity and working environment are improved; the pressures for lifting waste rocks out of well and separating coals and waste rocks are reduced; the effect of environmental friendliness is realized; and the supporting transportation cost for lifting waste rocks out of well is reduced.
