Description

Crushing plate for screening crusher Technical Field The utility model relates to the technical field of screening crushers, in particular to a crushing plate for a screening crusher. Background In the shale oil and coal exploitation process, ores, coal blocks and the like with larger sizes need to be crushed and screened for multiple times to reach the required specification range, and then subsequent procedures such as ore washing and ore dressing are carried out. At present, the main processing mode adopted is to carry out multistage crushing by using a screening crusher, wherein the abrasion in the screening crusher is serious in the multistage crushing process due to the large hardness of raw materials such as ore and the like, namely, in the multistage crushing process completed at one time, the later crushing plate is worn to influence the crushing effect. The crushing plate is mainly prepared from wear-resistant steel, and in order to solve the problems of rapid wear and serious wear of the crushing plate in the use process, wear-resistant materials are generally coated and welded on the main wear surface of the crushing plate so as to strengthen the crushing plate. However, the mode can not only cure the symptoms but also strengthen and weld the surface of the crushing plate, the operation is more complex, a great deal of time and cost are consumed, and the wear-resisting effect of the crushing plate which can be finally achieved is poor. Therefore, there is a need for a crushing plate for a screening crusher that is simpler to operate, has better wear resistance and can be used for a longer period of time. Disclosure of utility model The utility model aims to solve the problems of rapid and serious abrasion of a crushing plate in the conventional screening crusher for crushing ores and the like, and complicated and low-efficiency conventional repairing and maintaining modes. The utility model provides a crushing plate for a screening crusher, which can effectively relieve impact stress of raw materials such as ores on the surface of the crushing plate in the crushing process by arranging crushing teeth with different angles, reduce the action strength of the raw materials such as ores in unit area on the crushing plate, effectively delay the abrasion of the crushing plate and obviously prolong the service life of the crushing plate. The utility model is realized by the following technical scheme: The utility model provides a crushing plate for a screening crusher, which comprises a crushing plate body and a plurality of groups of crushing plate teeth arranged on the surface of the crushing plate body, wherein at least one plate tooth is convexly arranged on the surface of the crushing plate tooth, a main tooth and a plurality of auxiliary teeth are embedded on the surface of the plate tooth, and a plurality of protection teeth are embedded on the side wall surface, close to the auxiliary teeth, of the plate tooth. Preferably, an inclined slope is arranged on one side wall surface of the plate tooth, and the protection tooth is embedded in the inclined slope surface of the plate tooth. Preferably, the number of the protection teeth is 2-8, and a plurality of the protection teeth are uniformly arranged at intervals.
