PREFERRED EMBODIMENT

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figures 1-4 As shown, this utility model provides a wear-resistant liner for a mining crusher, including a support plate 1. Adjacent support plates 1 are movably fitted together. The outer surface of the support plate 1 is symmetrically provided with mounting grooves 11. Mounting blocks 12 are welded and connected in the mounting grooves 11. The welding is multi-layered to ensure that the bonding strength between the mounting blocks and the support plates is far greater than the impact force of the ore. A through bolt groove 13 is provided on one side of the mounting block 12. After the liner is installed, the support plate 1 is installed on the mining crusher. Specifically, the mounting block 12 in the mounting groove 11 is aligned with the point to be installed, and then the mounting block 12 is bolted to the mining crusher by inserting bolts into the bolt groove 13 to complete the fixing.

[0020] One side of the support plate 1 is detachably provided with a first liner 2 or a second liner 21. A through-type positioning groove 22 is symmetrically opened on one side of the support plate 1. Positioning posts 23 are symmetrically fixed to the inner sides of both the first liner 2 and the second liner 21. Four positioning posts 23 are provided on one of the first liner 2 or the second liner 21, and the four positioning posts 23 are arranged in a rectangular pattern. The positioning posts 23 are engaged in the corresponding positioning grooves 22. A groove 25 is symmetrically opened on one side of the support plate 1. Insert plates 24 are symmetrically fixed to the inner sides of both the first liner 2 and the second liner 21, and the insert plates 24 are engaged in the corresponding grooves 25. A retaining plate 26 is symmetrically fixed in the groove 25. Plate 26 and corresponding insert plate 24 are movably fitted together, and insert plate 24 and clamping plate 26 are connected by bolts. When installing the wear-resistant liner of the mining crusher, when first installing the first liner 2 or the second liner 21, the positioning pins 23 symmetrically arranged on the inner side of the liner are precisely engaged with the positioning groove 22 opened on one side of the support plate 1, and the liner is quickly positioned, initially limiting the planar displacement of the liner. At the same time, the insert plate 24 on the inner side of the liner is inserted into the groove 25 of the support plate 1. The clamping plate 26 in the groove 25 is tightly fitted with the insert plate 24, and then further tightened by bolts to ensure that the liner and the support plate are firmly connected and can withstand the strong impact and friction during ore crushing.

[0021] The outer side of the first lining plate 2 is provided with a plurality of vertical grooves 201 and horizontal grooves 202 distributed at equal intervals, and the vertical grooves 201 and the horizontal grooves 202 are alternately distributed. In the operation process of the crusher, if the first lining plate 2 is selected, the outer side of the first lining plate 2 is provided with the vertical grooves 201 and the horizontal grooves 202 distributed at equal intervals and alternately. When the ore particles impact the first lining plate 2, the grooves change the movement trajectory of the ore, diversify the impact angle of the ore, disperse the impact force, avoid local excessive wear, and simultaneously crush and grind the ore to a certain extent by the edges of the grooves, thereby assisting in improving the crushing effect.

[0022] The outer side of the second lining plate 21 is fixedly provided with a plurality of protrusions 211 distributed in a rectangular shape, and the outer side of the protrusion 211 is fixedly provided with a reinforcing column 212 in a symmetrical manner. If the second lining plate 21 is selected, the protrusions 211 and the reinforcing column 212 on the surface of the second lining plate 21 directly impact the ore. The protrusions 211 increase the pressure of the contact with the ore, strengthen the crushing effect, and the reinforcing column 212 enhances the structural strength of the protrusions, resists the impact of the ore, prevents the damage of the protrusions, and cooperates to ensure the long-term work of the lining plate in a complex stress environment.

[0023] The upper surface of the support plate 1 is fixedly provided with a positioning plate 3, the lower surface of the support plate 1 is provided with a plate groove 31 matched with the positioning plate 3, one side of the support plate 1 is fixedly provided with a plurality of insertion columns 32, and the other side of the support plate 1 is provided with column grooves 33 matched with the insertion columns 32. When it is necessary to expand or adjust the coverage range of the lining plate, the positioning plate 3 on the upper surface of the support plate 1 and the plate groove 31 on the lower surface of the other support plate can be matched, and the insertion column 32 on one side and the column groove 33 on the other side can be inserted and connected with each other, so that more support plates and lining plate assemblies can be flexibly spliced.

[0024] Working principle: when the mine crusher wear-resistant lining plate is installed, first, the first lining plate 2 or the second lining plate 21 is installed, and the positioning column 23 arranged in a symmetrical manner on the inner side of the lining plate is precisely clamped with the positioning groove 22 provided on one side of the support plate 1, so as to be quickly positioned and preliminarily limit the planar displacement of the lining plate; at the same time, the insertion plate 24 on the inner side of the lining plate is inserted into the recess 25 of the support plate 1, the clamping plate 26 in the recess 25 is tightly matched with the insertion plate 24, and the lining plate and the support plate are further fastened by bolts, so as to ensure that the connection between the lining plate and the support plate is firm and can withstand the strong impact force and friction force during the crushing of the ore;

[0025] In the operation process of the crusher, if the first lining plate 2 is selected, the outer side of the first lining plate 2 is provided with the vertical grooves 201 and the horizontal grooves 202 distributed at equal intervals and alternately. When the ore particles impact the first lining plate 2, the grooves change the movement trajectory of the ore, diversify the impact angle of the ore, disperse the impact force, avoid local excessive wear, and simultaneously crush and grind the ore to a certain extent by the edges of the grooves, thereby assisting in improving the crushing effect;

[0026] If the second lining plate 21 is used, the rectangularly distributed convex blocks 211 and the reinforcing columns 212 on the surface of the second lining plate 21 directly hit the ores, the convex blocks 211 increase the pressure intensity in contact with the ores, the reinforcing columns 212 enhance the structural strength of the convex blocks, resist the impact of the ores, and prevent the convex blocks from being damaged, and the two work together to ensure that the lining plate works durably under a complex stress environment;

[0027] After the lining plate is installed, the support plate 1 is installed on the mine crusher, specifically, the mounting block 12 in the mounting groove 11 is aligned with the point to be installed, and then the mounting block 12 is bolted and connected with the mine crusher by inserting the bolt into the bolt groove 13, and the fixing is completed.

[0028] When it is necessary to expand or adjust the coverage range of the lining plate, the positioning plate 3 on the upper surface of the support plate 1 is matched with the plate groove 31 on the lower surface of the other support plate, and the insertion column 32 on one side is inserted into the column groove 33 on the other side, so that more support plates and lining plate assemblies can be flexibly spliced.

[0029] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Therefore, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technologies, the present application also intends to include these modifications and variations.
