The invention discloses a crushing tooth assembly. A front tool face of the crushing tooth assembly comprises a tile-like groove surface on the front portion and a guide transition surface on the back portion. The guide transition surface is adjacent to the tile-like groove surface, and the adjacent joint is in a smooth transition mode. An included angle between the intersection position of the tile-like groove surface and a main back tool surface and the longitudinal section parallel to the moving direction of a crushing tooth is 5-60 degrees, so that the position, facing the moving direction of the crushing tooth, of the front portion of the intersecting line of the tile-like groove surface and the main back tool surface is in an inwards concave shape, and two tooth tops are arranged in the positions, at the two ends of the intersecting line, of the front portion of a front tool surface; and accordingly, when the crushing tooth conducts crushing operation, the tooth tops enter materials before the intersecting line adjacent to the tooth tops enters the materials. The two ends of the intersecting line are guided through the tooth tops to conduct collapsing on corresponding materials, and the intersecting line enters a material collapsed gap from the two ends to the middle in sequence, so that the crushing efficiency is substantially improved. The invention further provides a corresponding crushing tooth manufacturing method, a crushing tooth roller, a feed crusher, a coal mining machine and crushing equipment, and the crushing tooth assembly is applied to the crushing tooth roller, the feed crusher, the coal mining machine and the crushing equipment.
Description
technical field [0001] The present application relates to the technical field of crushing, in particular to a crushing tooth, and also provides a method for manufacturing the crushing tooth. The crushing teeth are mainly used in crushing equipment, such as feed crushers, mobile crushers and other crushers. [0002] The present application also relates to a crushing tooth assembly using the above crushing teeth, and a crushing tooth roller using the above crushing teeth or the crushing tooth assembly. In addition, the aforementioned crushing tooth, crushing tooth assembly, and crushing tooth roller can be used in equipment for performing excavation or tunneling work after adaptive adjustment. [0003] In addition, the present application also relates to a feed breaker using the crushing tooth or the crushing tooth assembly and the crushing tooth roller. The aforementioned crushing tooth, crushing tooth assembly and crushing tooth roller can also be applied to various other cr...
