Optimisation and Improvement of Coal Mining Machine Spherical Drum End Plate Structure
On the basis of a brief introduction to the structure of the end plate of the coal mining machine drum and its function,the problems existing in the practical application of the spherical drum end plate are analysed,which are mainly the small gap between the end plate and the coal wall,which exacerbates the wear and tear of the structure of the end plate and shortens its service life.The structural optimisation is carried out by replacing the flat end plate with a butterfly end plate,and the overall structure of the butterfly end plate and the arrangement of the teeth on the circumference are designed in detail,with a total of 18 teeth,all of which are divided into five major types,and the installation angles of the teeth of different types are different.The optimised disc end plate is applied to the spherical drum practice,and after the field test application,it is found to have achieved very good results,and the service life of the end plate is extended by 20％.
