Embodiment Construction

[0011] Embodiments of the present invention are further described below in conjunction with accompanying drawings:

[0012] Such as figure 1 , 2 As shown, the grid bar of this grid includes a grid bar body 1, and the grid bar body 1 is fixed on the grid outer frame 3 by fasteners 2. The upper surface of the grid bar body 1 is provided with a wear-resistant layer 4, and the grid bar body 1 The cross section is inverted trapezoidal.

[0013] Since the cross-section of the grid body 1 is an inverted trapezoid, when a qualified ore block passes through the grid, it is difficult to touch the left and right sides of the grid body 1, which reduces the wear area, and the upper surface of the grid is equipped with Wear-resistant layer 4, when the ore block falls on the upper surface of the grid body 1, under the protection of the wear-resistant layer 4, the grid body 1 is not easy to wear, thus greatly prolonging the service life of the grid and reducing maintenance cost.

Abstract

The invention belongs to the field of crushers, and in particular, relates to a grille grid. The grille grid comprises a grid body; the grid body is fixed on a grille outer frame through a fastening piece; a wear resisting layer is arranged on the upper surface of the grid body; and the cross section of the grid body is an inverted trapezoid. As the cross section of the grid body is the inverted trapezoid, when ore blocks with qualified sizes pass through a grille, the ore blocks are not easy to collide with the left and right side surfaces of the grid body, and the wear area is reduced; as the wear resisting layer is arranged on the upper surface of the grid, when the ore blocks fall on the upper surface of the grid body, under the protection effect of the wear resisting layer, the grid body is not easy to wear, the service life of the grid is largely prolonged, and the maintenance cost is reduced; each grid body is fixed on the grille outer frame through the fastening piece; and when single grid body is worn, the corresponding grid body only needs to be replaced, and the whole grille has no need to be replaced, so that the maintenance operation is convenient, and the cost is lower.

Description

technical field [0001] The invention relates to a grid bar and belongs to the field of crushers. Background technique [0002] Grilles are usually used in crushers to screen ore blocks, but the gratings in traditional gratings have poor wear resistance and are often worn during use, and the gratings use an integral structure, and the gratings need to be removed as a whole after the gratings are worn , replacement, repair and maintenance costs are high. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide a grill bar with high wear resistance and low maintenance cost. [0004] The grid bar of the present invention comprises a grid bar body, the grid bar body is fixed on the grid outer frame by fasteners, the upper surface of the grid bar body is provided with a wear-resistant layer, and the cross section of the grid bar body is an inverted trapezoid . [0005] The c...
