Description
Technical field
The utility model relates to coal mining field, is specifically a kind of helix drum of alternating current traction coal-winning machine.
Background technology
In recent years, China's coal-cutting machinery industry development is swift and violent, and end national coal-cutting machinery manufacturing enterprise in 2010 and reach 24, volume of production and marketing about 800 multiple stage, production capacity reaches about 1500.From domestic coal machine competition situation, Mei Ji manufacturing enterprise of China interfereed with the development slowly by the planned economy era, and not only technical level is lower, and product is single.Although skill upgrading is very fast in recent years, but compared with external coal machine giant, the reliability and stability of China's coal mining machinery equipment complete machine are still not strong, lack the top brand of industry, financial strength and R&D capability also has one section of gap with international most advanced level, the production aspect of colliery extractive equipment and external gap are comparatively large in the open, large and real picture that Bu Qiangshi China coal machine profession is current.
Coal-winning machine is one and integrates large-scale complicated system that is mechanical, electric and hydraulic pressure, and work under bad environment, will cause the interruption of whole coal work if there is fault, cause huge economic loss.Along with the development of coal industry, the function of coal-winning machine gets more and more, the structure of himself, composition more sophisticated, and the reason thus broken down is also thereupon complicated.
Utility model content
The purpose of this utility model is the helix drum providing a kind of alternating current traction coal-winning machine at this; This helix drum is a cylinder with helical blade, pick is contained in the toothholder cover be welded on helical blade, and during work, cylinder rotates and moves radially, the broken coal of cut, by helical blade, the axis direction of coal along cylinder is pushed out again, put into face conveyor.
The utility model realizes like this, construct a kind of helix drum of alternating current traction coal-winning machine, it is characterized in that: described helix drum comprises cutting drum spray nozzle, cutting drum pick box, cutting drum blade, cutting drum sleeve pipe, cutting drum pick, plinth, end plate;
Cutting drum blade welds with cutting drum sleeve pipe and carries coal, and cutting drum pick box is loaded onto cutting drum pick and carried out coal cutting after welding with cutting drum blade, and coal fragmentation got off loads working face conveyor, and plinth welds with cutting drum sleeve pipe.
The utility model has the advantage of: alternating current traction Shearer Helical Drum described in the utility model; This helix drum is a cylinder with helical blade, pick is contained in the toothholder cover be welded on helical blade, and during work, cylinder rotates and moves radially, the broken coal of cut, by helical blade, the axis direction of coal along cylinder is pushed out again, put into face conveyor.
