Problems solved by technology

[0002] At present, most coal shearers and roadheaders are drum-type rotary milling and blanking, and excavators are mostly hydraulically driven single buckets or single-tooth impact heads for digging and breaking materials. With the development of science and technology, reciprocating impact shearers and reciprocating shearers have emerged. Impact roadheaders and reciprocating impact excavators are collectively referred to as reciprocating impact excavators. The impact head of the reciprocating impact excavator has a high block rate of materials, less dust, and low energy consumption. Thick coal seam or high coal seam or thick rock layer or high rock layer or thick cement concrete or wide cement concrete or thick asphalt concrete or wide asphalt concrete or thick plate mudstone or wide plate mudstone, in order to solve the needs of mining thick The needs of coal seam or high coal seam or thick rock formation or high rock formation or thick cement concrete or wide cement concrete or thick asphalt concrete or wide asphalt concrete or thick plate mudstone or wide plate mudstone, the present invention proposes a A multi-layer impact head with low resistance and high efficiency mining equipment
