Technical Field
[0001] The utility model relates to the technical field of coal mining machines, in particular to a shock-absorbing base for coal mining machines. Background Art
[0002] As we all know, a coal mining machine is a large and complex system integrating mechanical, electrical and hydraulic functions. It is one of the important equipment for realizing the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve the goals of high output, high efficiency and low consumption. In longwall coal mining faces, coal mining machines need to use shock-absorbing bases during coal mining.
[0003] In real life, when the existing shock-absorbing base is in use, due to its relatively simple structure, it cannot effectively fix itself and the ground stably. When the coal mining machine generates a large vibration force when mining coal, the shock-absorbing base of the coal mining machine will produce a certain shaking on the ground, thereby affecting the shock-absorbing effect of the shock-absorbing base itself. Therefore, the practicality is not very good and there is still room for improvement. Utility Model Content
