The straight embossed strips 1, the rhombus embossed strips 2 and the V-shaped embossed strips 6 are interlaced arranged, that is, one row of the rhombus 5 embossed strips 2 is arranged between the first and the second wide embossed ribs, and another row of the rhombus embossed strips 2 is arranged between the third and the fourth wide embossed ribs, and the V-shaped embossed strips 6 is arranged between the second and the third wide embossed ribs. The overlapped straight lines and fish-scale embossment cover the entire metal plate, and the four wide 20 embossed ribs can protect the easily-linear-worn positions of the metal plate, and the rhombus embossed strips 2 and the V-shaped embossed strips 6 are used to protect the easily-punctiform-worn positions, which can prolong the service life of the metal plate effectively, and can lead the running direction for transporting articles, meanwhile the overlap joints are reduced, so the running friction is decreased and the 25 energy consumption is lowered. .

Embodiment 18:

As shown in Fig. 18, this embodiment provides an embossed structure on the 18 metal surface, and the embossed structure is cladded on the metal surface by using laser, the embossed structure is a straight-line embossment with the height higher than the surface of the metal. The straight-line embossment is formed by the straight embossed strips 1 with the height of 2.5mm. The overlap rate of the straight 2017100953 18 Μ 2017 5 embossed strips 1 is 30%-50%. The straight-line embossment covers the entire metal plate to conduct protecting. There is no overlap joint, so the running friction for transporting the articles is decreased and the energy consumption is lowered, that is, it can effectively protect the metal plate without costing too high. 0 Embodiment 19:

As shown in Fig. 19, this embodiment provides an embossed structure on the metal surface, and the embossed structure is cladded on the metal surface by using laser, the embossed structure includes an embossed block 2 and a closely interweaved rhombus embossment with the height higher than the metal surface. 5 The closely interweaved rhombus embossment is formed by the rhombus embossed strips 3, and the length of the side of the rhombus is 120mm, and the degree of the acute angle is 60°. The closely interweaved rhombus embossment is symmetrically arranged along the central axis of the metal plate. The angle and the size of the rhombus embossed strip 3 of the closely interweaved rhombus embossment are 20 redesigned, and meanwhile the embossed block 2 are cladded at both ends of the metal plate, so as to increase the wear-resisting support area on the surface of the metal plate, decrease the direct contact area between the metal basic plate and the transported articles, which can protect the basic body in a greater degree, enhance the wear-resisting performance entirely and prolong the service life of the metal plate. 25 Besides, in this embodiment, the powdered coal accumulates in the rhombus close zone to form a lubricant layer on the surface of the middle plate, which can decrease the friction between the scraper blade and the plate surface or between the chain and the plate surface, and thus decrease running resistance, and lower the energy 19 consumption and the worn rate of the wear-resisting strip. 2017100953 18 Μ 2017

Additionally, it should be understood that even though this specification is described as exemplary embodiments, each embodiment include not only one method solution, which is considered to make this specification clear. The 5 specification should be deem as a whole by those ordinary skilled in this art, the method solution of every embodiment can be can be properly devised to form other embodiments understood by those skilled in this art. 20
