Problems solved by technology

However, these studies cannot fundamentally change the wear and tear of the material itself of the equipment or components, and can only prolong its service life in a short period of time, but at the same time greatly increase the manufacturing cost and use cost of the equipment or components
There has also been a waste of high-quality, expensive materials used in ordinary working conditions

Abstract

The invention relates to a surface of bionic wear-resistant structure, in particular to a surface of ribbing bionic wear-resistant geometry structure; the surface of bionic wear-resistant structure is based on the squama surface of the soil and cave animal pangolin and has geometry structural characteristics of soil resistant grinding medium. The surface of bionic wear-resistant structure aims at solving the abrasion problem of the prior particulate material contact parts. The surface of bionic wear-resistant structure is characterized in that: the structure of original equipment or element and the surface of the contact material is changed; and the surface is newly provided with a series of ribbing structure which has a certain geometric parameters and space. The shape of the bionic wear-resistant structure is y=asin(bx+c), wherein a is amplitude, b is frequency and c is initial phase, and 0 F16S 5 / 00 F16S 1 / 00 A01B 15 / 00 A01B 33 / 10 A01C 5 / 00 A01D 13 / 00 B65G 15 / 30 B67C 11 / 00 B65D 90 / 02 E02F 9 / 00 F16L 57 / 06 4 3 1 2008 / 1 / 30 101225919 2008 / 7 / 23 000000000 Jilin University 130012 Tong Jin Rong Baojun Ma Yunhai Chen Donghui Sun Jiyu Zhou Jiang Yan Jiulin Chang Zhiyong Zhang Jinbo zhushi lin 22201 The Patent Agency of Jilin University No.83 Liberation Main Street, the City of Changchun, Jilin Province 130023

Description

Technical field: [0001] The invention relates to a bionic wear-resistant structure surface, in particular to a ribbed bionic wear-resistant geometric structure surface, which can be applied to soil-contacting parts of agricultural machinery, loading parts of earthwork loading machinery and bulk material conveying parts, such as pipelines, Conveyor belts, hoppers, silo walls, etc. technical background: [0002] In the process of industrial production, the wear of equipment and components in contact with bulk materials is very serious, which belongs to the type of abrasive wear. This wear is a major cause of equipment and component failure. At present, in order to reduce this wear, people mainly focus on improving the service conditions of the workpiece, improving the wear resistance of the material itself, developing higher wear-resistant materials, the influence of abrasive shape and performance on wear resistance and the mechanism of abrasive wear exploration etc. Howeve...
