Description

Technical Field

[0002] With the development of modern equipment, mechanical coal mining has become the industry trend. With the continuous improvement of the mechanization level, the coal mining efficiency has reached a new level. In coal mining, generally, the initially mined coal blocks are relatively large and not suitable for direct loading and transportation. At this time, the large coal blocks need to be crushed so that they can be directly loaded and transported after being transported out. At present, for the coal mining crushing devices, one is generally to use relatively arranged gear teeth to squeeze the coal blocks to make them crushed, and the other is to use the vibration method. Both of these two coal block crushing devices have certain deficiencies, including simple structure, inability to perform step-by-step crushing, poor crushing effect, and inability to well meet the modern requirements, thus being relatively inconvenient and having a certain impact during use. Therefore, the utility model provides a coal block crushing device for coal mining herein. Content of the Utility Model
