Description
Technical Field
The invention relates to the field of scrapers, in particular to a novel high-strength high-wear-resistance scraper with a crushing function.
Background
At present, the tensile property and the wear resistance of the scraper for scraper conveyors are considered in the design and manufacture process in China, so the scraper is produced by adopting a forging process. However, in the actual operation process of the scraper with the scraper chain, the scraper often encounters large waste rocks, coal blocks and other materials to block the operation of the scraper. When the material is blocked, huge pressure can be generated between the material and the contact surface of the scraper, so that the scraper is seriously deformed and broken until the scraper fails. Under normal working conditions, the failure of the scraper caused by the material jamming accounts for nearly 20% of the total failure number of the scraper; under severe working conditions, such as working surfaces with large gangue content and high hardness, the proportion of bending, deformation and fracture failure of the scraper is higher. The loss of the scraper plate caused by the blockage of the materials to mine the mine is huge every year. However, due to the limitation of the forging process of the existing scraper, the scraper is difficult to have the function of crushing large materials when being designed.
During use, the squeegee can perform the following types of operations: the large material can be crushed only by the impact tip on the scraper, so that the failure of the scraper caused by bending, deformation and fracture of the scraper due to the blocking of large materials is effectively reduced.
However, although the prior scraper has simple structure and convenient operation, the prior scraper has single function, when the prior scraper is blocked by large materials in the running process, the contact surface of the scraper and the massive material can generate great acting force to cause the bending, deformation and even fracture failure of the scraper, the scraper in the prior art is easy to bend, deform, fracture and even fail when being blocked, but also can cause the secondary to scraping other parts of trigger and even make the complete machine to destroy after it became invalid, certain adverse effect has, current scraper blade shock-absorbing capacity is not high, long-term antagonism material's impact, reduce the life of scraper blade easily, certain adverse effect has, current scraper blade live time overlength, strike sharp wearing and tearing easily, the ability of the broken material of sharp impact is easily reduced, certain adverse effect has, for this reason, we propose a novel high strength high wear-resisting scraper blade with crushing function.
