It can cuts the whole seam height in one trip, and accommodate the changing of seam thickness and floor undulation. Should the shearer adaptability like, the power is big and adopt a coal efficiency high, operate in brief and check to fix convenience. This design mainly carrieson a project design to the whole machine of the shearer, spreading to move to wait a related design towards the cutting drum to carry on structure. The MG180/435-W type liquid presses to lead to shearer curved the ranging arm of the cutting drum, and the electrical engineering horizontal arranges in the ranging arm. There is no motive delivering between ranging arm and gearhead conjunction and canceling spiral umbrella wheel gear and structure a complicated stalk. In the design of the cutting drum spread move , the exploitation keeps the general theory that wheel gear and planet wheel gears constituting to decelerate a machine is a design. Designing to suit a deceleration machine which mows an usage, and will it and the mineral use electric motor to combine directly, simplifying to the cutting drum to spread to move a decoration. The creative of this design: Cut a deceleration machine of mowing the department to install in the ranging arm, used two round to increase center to be apart from, so as to make the total piece of wheel gear reduced, and raised to spread to move an efficiency. The structure full general clutch installs on the electrical engineering stalk, making the moving convenience and safety. In the Design medium to 2K() type the planet decelerated a machine to carry on excellent turn to go together with teeth, adopt height to change, and did a homologous check. Be promising to need of spread under circumstance of moving the ratio, make the 2K() of design type planet decelerate machine physical volume minimum.The shearer ；The cutting drum ；The planet decelerates a machine ；The ranging arm
