Technical Field

[0001] The utility model relates to the field of crusher tooth rollers, in particular to a coarse tooth profile structure of a screening type crusher. Background Art

[0002] A crusher is a pulverizing machine used in the processing of metal ores and non-metallic ores. It can crush the mined raw ore into small particles by extrusion and bending. The quality of a crusher mainly depends on the design of its tooth roller. The tooth roller shaft is the most important working part of the crusher, and the teeth are important working parts that directly contact the material. They withstand a large cyclic rotation impact force, so the main shaft is required to have high strength and toughness.

[0003] The toothed roller is an important working component that directly contacts the material. Due to the working characteristics of the crusher, the toothed roller needs to have strong impact resistance and wear resistance. Long-term crushing work causes the teeth to be damaged, but most toothed rollers are one-piece designs, which is not convenient for replacing a single tooth. As a result, when individual teeth are damaged, the entire toothed roller needs to be replaced. Because some teeth are not damaged or have reached the limit of use, it causes waste of parts. Utility Model Content

[0004] In order to make up for the shortcomings of the prior art, most tooth rollers are of integrated design, which makes it inconvenient to replace a single tooth. As a result, when individual teeth are damaged, the entire tooth roller needs to be replaced. Because some teeth are not damaged or have reached their use limit, it causes waste of parts and other problems. The utility model proposes a coarse tooth shape structure of a screening crusher.
