Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment, and in particular relates to a wear-resistant lining plate of a mining crusher. Background Art

[0002] The crusher liner is installed inside the crusher casing, and it will create a gap with the main components of the crusher. During the operation of the crusher, the hammer head and the liner will be impacted and squeezed when crushing the material, so that the material can be crushed. The liner protrudes inside the crusher. Because the equipment is a consumable equipment, that is, when working, as the working time extends, the internal parts gradually wear out. When the wear reaches a certain extent, the equipment can no longer work smoothly. The liner can play a protective role inside the equipment, reducing the wear or damage of certain parts inside the crusher, which can reduce the impact on equipment efficiency and reduce the cost investment required for parts maintenance. The liner can improve the efficiency and production capacity of the crusher, because the liner generally has serrations. When the equipment is crushing the material, the serrations can effectively crush the material, and the effect is very obvious. However, this effect will cause friction between the serrations and the material, causing the serrations to gradually wear out and lose their function. Therefore, better steel plates can be used to process the liner to improve its own hardness and wear resistance, which is also very helpful in improving the labor intensity and production capacity of the equipment.

[0003] At present, most of the existing crusher liners are installed and fixed by bolt connection during installation. The liner is installed on the shell. However, after long-term use, the rolling of gravel can easily cause impact on the bolt head. Frequent impact will cause the bolt head to be damaged or loose, so the liner or bolt needs to be frequently replaced regularly, which greatly reduces the efficiency of the crusher. For this reason, we propose a wear-resistant liner for mining crusher. Utility Model Content

[0004] The purpose of the utility model is to provide a wear-resistant lining plate for a mine crusher to solve the existing problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant lining of a mining crusher, comprising a lining, a sinking trough and a sealing plate, a crushing block fixedly installed on the top of the lining, a sealing plate slidingly arranged between two crushing blocks at the corners around the lining, a sinking trough provided on the lining below the sealing plate, a contraction groove and a groove are respectively provided on opposite sides of the two crushing blocks at both ends of the sealing plate, the two ends of the sealing plate are respectively placed inside the contraction groove and the groove and are slidably connected to their inner walls, an ejection spring is provided inside the contraction groove, and the two ends of the ejection spring are respectively fixedly connected to the inner wall of the contraction groove and one end of the sealing plate.

[0006] Preferably, a magnetic block is provided on the inner wall surface of one side of the groove, and the magnetic block is fixedly installed on the inner wall surface of one side of the groove by inlaying, and the sealing plate is made of metal.

The limiting blocks extend to the inside of the limiting groove and are slidably connected to its inner wall.

[0008] Preferably, a notch is provided at one end of the top of the sealing plate, and the notch is provided at one end of the top of the sealing plate close to the groove but does not enter the interior of the groove.

[0009] Preferably, a through hole of the lining plate is opened at the bottom of the sink, and the through hole passes through the lining plate and extends to the bottom of the lining plate. A bolt extending to the outside is arranged inside the through hole.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. By adopting the sinking groove method, the bolt head of the bolt is sunk into the sinking groove, and then a retractable sealing plate is set on the top. Under the action of the ejection spring, the ejection contraction groove is lowered so that its two ends are respectively placed inside the contraction groove and the groove to realize the positioning of the sealing plate, thereby achieving the purpose of protecting the bolts inside the sinking groove and effectively avoiding the damage caused by gravel hitting the bolts.

[0013] 2. By setting a magnetic block on the inner wall surface of one side of the groove, using magnetic attraction and cooperating with the ejection spring, the two ends of the sealing plate are subjected to force in the same direction, thereby ensuring the stability of the sealing plate and avoiding the situation where the sealing plate is separated from the top of the sink due to vibration during the operation of the equipment.
