Development of New Type of Cantilever Roadheader Horizontal Axis Cutting Head
As the core component for rock breaking and coal falling in coal mining machinery,the horizontal axis cutting head has higher rock breaking efficiency and adaptability compared to the vertical axis cutting head when cutting hard rocks.Compared with the Sandvik AHM105 horizontal axis cutting head structure,a new type of cantilever roadheader horizontal axis cutting head has been successfully developed through innovation in connection structure,head body structure,tooth seat structure and large end structure.It adopts an eight sided structure connection,front and rear cutting head body combined with anti shear pin welding,J-shaped slope tooth seat,and integrated wear-resistant head body large end structure.Through underground application,it has been verified that the cutting head has high reliability and stability in the process of cutting the whole rock.The research content provides reference for the development and innovation of horizontal axis type cutting heads,and has certain practical and promotional value.
