Detailed Description
The present utility model will be described in further detail with reference to the following embodiments and the accompanying drawings, in order to make the objects, technical solutions and advantages of the present utility model more apparent. The exemplary embodiments of the present utility model and the descriptions thereof are used herein to explain the present utility model, but are not intended to limit the utility model.
Referring to fig. 1, 2 and 3, the high-strength scraper of the present utility model comprises a scraper body 1, wherein the scraper body 1 is integrally forged from 40Cr, a first groove 11 is formed in one side of the scraper body 1 facing to materials, a reinforcing rib assembly 2 is arranged in the first groove 11, the reinforcing rib assembly 2 can improve the strength of the scraper body 1, and the wear resistance of the scraper body 1 can be improved.
The stiffener assembly 2 includes a first stiffener 21 and a second stiffener 22, the first stiffener 21 being larger in size than the second stiffener 22. The first reinforcing rib 21 is located at an intermediate position in the width direction of the first groove 11, three second reinforcing ribs 22 are located at one side of the first reinforcing rib 21, and three other second reinforcing ribs 22 are located at the other side of the first reinforcing rib 21. The first reinforcing rib 21 and the second reinforcing rib 22 are integrally formed with the squeegee body 1. The first reinforcing rib 21 and the second reinforcing rib 22 mainly play a role in increasing the strength of the squeegee body 1, and also play a role in wear resistance to some extent.
The second groove 12 is formed in one side, opposite to the first groove 11, of the scraper body 1, the toughness of the scraper body 1 can be improved due to the arrangement of the second groove 12, the weight of the scraper body 1 can be reduced, the cost is saved, and the service life of the scraper body 1 is prolonged.
