Description

Front conveying structure for crushing broken stone Technical Field The utility model relates to a stone crushing technology, in particular to a technology for conveying stone blocks of a stone crusher. Background In the construction field, various building materials can be formed by pulverizing stone blocks, for example, various colored sands can be formed after pulverization, and the method is applied to the field of building decoration. The equipment used for comminution is, for example, a different type of crusher, such as a counter-impact crusher or a jaw crusher, which is selected according to the size of the rock or the size of the particle to be crushed, and a plurality of crushers can be used in series to obtain the desired size gravel. In a typical shredder, it is necessary to continue the addition of rocks to the opening of the shredder, which is often difficult to accomplish if the vehicle hopper is directly unloaded to the opening, resulting in too much rocks being spilled to the surrounding area, and difficult to automate if manual feeding is used.
