A connecting slot is provided at a symmetrical position on the side surface of each jaw plate protrusion. A high-strength cover is fastened to the outer cover of each jaw plate protrusion. Two connecting strips are integrally connected to the inner wall of the high-strength cover and are inserted into the connecting slots.

[0007] By adopting the above technical solution, the damaged parts can be disassembled and replaced flexibly and conveniently, making it highly practical.

[0008] Furthermore, a plurality of breaking nails are fixedly connected at the apex of the arc on the outer surface of the high-strength cover, and the plurality of breaking nails are arranged in a straight line at the apex of the arc on the outer surface of the high-strength cover.

[0009] By adopting the above technical solutions, crushing performance can be effectively improved.

[0010] Furthermore, one end of the jaw plate body is provided with an outer cover fixing position, and one end of the high-strength cover is fixedly connected with a fixing end, which is fixedly installed at the outer cover fixing position.

[0011] By adopting the above technical solution, the high-strength cover can be limited and fixed.

[0012] Furthermore, a through hole is provided on the outer surface of the fixed end, and a threaded hole is provided at the fixing position of the outer cover, with the through hole and the threaded hole corresponding to each other.

[0013] By adopting the above technical solution, the fixing end can be firmly fixed to the fixing position of the outer cover by bolts.

[0014] Furthermore, the high-strength cover has a shape that matches the shape of the jaw plate protrusion, and the high-strength cover tightly wraps around the outside of the jaw plate protrusion.

[0015] By adopting the above technical solutions, the crushing operation can be carried out stably.

[0016] Furthermore, a jaw plate fixing position is provided at the upper end of the jaw plate body.

[0017] By adopting the above technical solution, the installation of the pressure strip is facilitated.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows for easy replacement of damaged structures by removing the bolts that fix the end to the outer cover fixing position, then directly pulling out the high-strength cover to remove it from the jaw plate protrusion. The connecting strip inside the high-strength cover to be replaced is then inserted into the connecting slot. Finally, the fixing end is installed on the outer cover fixing position using bolts. This allows for flexible disassembly and replacement of damaged structures, making the replacement operation flexible, convenient, and highly practical. Furthermore, the use of multiple high-strength covers allows for flexible replacement of damaged parts, avoiding the need to replace the entire jaw plate and effectively reducing overall maintenance costs.

[0020] 2. This utility model, by setting multiple crushing nails on the outer surface of the high-strength cover, can use the crushing nails to crush the object to be crushed. Compared with the existing arc-shaped protrusion structure, the crushing efficiency is effectively improved and the practicality is further enhanced. Attached Figure Description

[0025] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 , Figure 2 , Figure 3 The easily replaceable jaw plate casting for a mining crusher includes a jaw plate body 1. Multiple jaw plate protrusions 6 are integrally connected to one outer surface of the jaw plate body 1. A connecting slot 7 is symmetrically positioned on the side surface of each jaw plate protrusion 6. A high-strength cover 3 is fastened to the outer cover of the jaw plate protrusions 6. Two connecting strips 8 are integrally connected to the inner wall of the high-strength cover 3 and are inserted into the connecting slots 7. An outer cover fixing position 10 is provided at one end of the jaw plate body 1. A fixing end 5 is fixedly connected to one end of the high-strength cover 3 and is fixedly installed at the outer cover fixing position 10. A through hole is provided on the outer surface of the fixing end 5, and a threaded hole is provided at the outer cover fixing position 10, with the through hole and threaded hole corresponding in position. The shape of the high-strength cover 3 matches the shape of the jaw plate protrusions 6, and the high-strength cover 3... The cover 3 tightly wraps around the outside of the jaw plate protrusion 6. The upper end of the jaw plate body 1 is provided with a jaw plate fixing position 2. When replacing the cover, the bolts fixing the fixing end 5 to the outer cover fixing position 10 can be removed, and then the high-strength cover 3 can be directly pulled out to remove it from the jaw plate protrusion 6. At this time, the damaged structure can be disassembled. Then, the connecting strip 8 on the inside of the high-strength cover 3 to be replaced is inserted into the connecting slot 7. Finally, the fixing end 5 is installed on the outer cover fixing position 10 with bolts. This allows for flexible disassembly and replacement of the damaged structure. The replacement operation is flexible and convenient, and it is highly practical. At the same time, by setting multiple high-strength covers 3, the damaged parts can be replaced flexibly, avoiding the need to replace the entire jaw plate, which can effectively reduce the overall maintenance cost.

[0027] Reference Figure 1 Multiple crushing nails 4 are fixedly connected at the arc apex position on the outer surface of the high-strength cover 3. The multiple crushing nails 4 are arranged in a straight line at the arc apex position on the outer surface of the high-strength cover 3. By setting multiple crushing nails 4 on the outer surface of the high-strength cover 3, the crushing operation of the object to be crushed can be carried out by the crushing nails 4. Compared with the existing arc protrusion structure, the crushing efficiency is effectively improved and the practicality is further improved.

[0028] Working principle: When in use, first install the jaw plate in the designated position. After installation, it can be used normally. During the crushing process, multiple crushing nails 4 are set on the outer surface of the high-strength cover 3. The crushing nails 4 can be used to crush the object to be crushed. Compared with the existing arc-shaped protrusion structure, the crushing efficiency is effectively improved. If the crushing structure is damaged during use, the bolts that fix the fixed end 5 to the outer cover fixing position 10 can be removed. Then, the high-strength cover 3 can be pulled out directly to remove it from the jaw plate protrusion 6. At this time, the damaged structure can be disassembled. Then, the connecting strip 8 on the inner side of the high-strength cover 3 to be replaced is inserted into the connecting slot 7. Finally, the fixed end 5 is installed on the outer cover fixing position 10 with bolts. At this time, the damaged structure can be flexibly disassembled and replaced. The replacement operation is flexible and convenient and highly practical.
