It is mainly used for medium and fine crushing of various ores and rocks. The liner structure is an important component of the cone crusher operation. The liner structure is divided into a dynamic liner assembly and a static liner assembly. The dynamic liner assembly includes a dynamic cone and a liner.

[0003] The utility model patent application document with publication number "CN217120361U" discloses a new type of dynamic cone liner for cone crusher, which is mainly composed of a dynamic cone liner body, a slot, a strip, a positioning slot, a positioning block, a fixed socket and an insertion rod. The technical solution is to install four dynamic cone liner bodies around the dynamic cone so that the positioning block enters the interior of the positioning slot, thereby improving the sealing strength between two adjacent dynamic cone liner bodies, and by turning the knob, the fixed plug plates can be driven to be inserted into the interior of the fixed socket in turn, which is convenient for installation and fixation, and improves the connection strength. When a single dynamic cone liner body is damaged, it can be easily disassembled and replaced, thereby improving work efficiency and facilitating use.

[0004] The new movable cone liner for the cone crusher disclosed in the above document has the following defects: after the movable cone liner body is impacted for a long time, the movable cone liner body will be recessed toward the movable cone side, and when the recessed part of the movable cone liner body is located on one side of the limiting groove, the movable cone liner body will be recessed into the interior of the limiting groove, which may affect the sliding of the movable plate in the limiting groove, making it impossible for the fixed plug plate to detach from the fixed plug hole, resulting in the inability to separate the movable cone liner body from the movable cone. Utility Model Content

[0005] The utility model aims at providing a lining plate structure of a cone crusher, which solves the problem that a moving cone lining plate may not be separated from the moving cone after being recessed.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a lining plate structure of a cone crusher, comprising a moving cone and a lining plate, wherein the outer surface of the moving cone is provided with a mounting groove, the lower surface of the moving cone is provided with a bottom plate, one side of the bottom plate is provided with a limiting groove, one side of the lining plate is provided with a connecting block, the connecting block is cooperatedly installed in the interior of the mounting groove, the outer surface of the connecting block is provided with a placement groove, the inner bottom of the placement groove is provided with a sliding groove, the inner surface of the sliding groove is provided with a spring, the other end of the spring is provided with a slide plate, the slide plate is slidably connected in the interior of the sliding groove, the interior of the placement groove is provided with a frame, one end of the slide plate is provided with a limiting block, one end of the limiting block passes through the frame and is cooperatedly installed in the interior of the limiting groove.

[0008] Furthermore, a through hole is provided at the inner bottom of the limiting groove, and one end of the through hole passes through the bottom plate and extends downward.

[0009] Furthermore, a groove is provided at the other end of the bottom plate, a baffle is connected to the inner thread of the groove, and a clamping groove is provided on the lower surface of the baffle.

[0012] Furthermore, a plurality of crushing grooves are provided on the other side of the liner.

[0013] The utility model has the following beneficial effects:

[0014] (1) The utility model avoids the problem that after the lining plate is hit, the concave part of the lining plate is embedded in the interior of the moving cone, which affects the separation of the moving cone and the lining plate. The baffle plate is removed from the interior of the groove, and then the ejector pin is inserted into the through hole so that one end of the ejector pin contacts the limit block. Then the ejector pin is pushed upward so that the ejector pin pushes the limit block. At the same time, the slide plate moves into the slide groove and compresses the spring. When the outer surface of the limit block is flush with the outer surface of the frame, the lining plate can be pulled outward to complete the separation of the lining plate and the moving cone, thereby achieving a better practical effect.

[0015] (2) The utility model uses the auxiliary groove and the auxiliary block in coordination, so that the slide plate moves more smoothly in the slide groove. When the spring pushes the slide plate, the auxiliary block slides along the auxiliary groove to ensure that the slide plate always moves along the predetermined trajectory, avoiding movement deviation caused by vibration or uneven force, and achieving a better auxiliary effect.

[0016] (3) The crushing grooves provided in the utility model can increase the contact area between the material and the liner, making the material easier to crush, thereby improving the overall crushing effect of the equipment. At the same time, during the crushing process, the material has a greater impact force on the liner, and the crushing grooves can disperse the impact force to multiple groove bodies, thereby avoiding excessive wear of the liner locally and extending the service life of the liner.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 As shown, the utility model is a liner structure of a cone crusher, comprising a moving cone 1 and a liner 2, a mounting groove 101 is provided on the outer surface of the moving cone 1, a bottom plate 3 is installed on the lower surface of the moving cone 1, a limiting groove 301 is provided on one side of the bottom plate 3, a connecting block 4 is provided on one side of the liner 2, the connecting block 4 is cooperatively installed inside the mounting groove 101, a placement groove 401 is provided on the outer surface of the connecting block 4, a slide groove 402 is provided on the inner bottom of the placement groove 401, a spring 5 is installed on the inner surface of the slide groove 402, a slide plate 6 is installed on the other end of the spring 5, the slide plate 6 is slidably connected inside the slide groove 402, a frame 7 is installed inside the placement groove 401, a limiting block 8 is installed on one end of the slide plate 6, one end of the limiting block 8 passes through the frame 7 and is cooperatively installed inside the limiting groove 301;

[0028] A through hole 302 is formed at the inner bottom of the limiting groove 301, and one end of the through hole 302 passes through the bottom plate 3 and extends downward;

[0029] The other end of the bottom plate 3 is provided with a groove 303, the inner thread of the groove 303 is connected with a baffle 9, and the lower surface of the baffle 9 is provided with a slot 901;

[0030] When the moving cone 1 and the lining plate 2 need to be separated, the baffle plate 9 is taken out from the inside of the groove 303, and then the ejector pin is inserted into the through hole 302, so that one end of the ejector pin contacts the limit block 8, and then the ejector pin is pushed upward, so that the ejector pin pushes the limit block 8, and at the same time, the slide plate 6 moves into the slide groove 402 and compresses the spring 5. When the outer surface of the limit block 8 is flush with the outer surface of the frame 7, the lining plate 2 can be pulled outward to complete the separation of the lining plate 2 and the moving cone 1;

[0031] An auxiliary groove 403 is formed on the inner surface of the slide groove 402, and an auxiliary block 601 is formed on the outer surface of the slide plate 6. The auxiliary block 601 is slidably connected to the inside of the auxiliary groove 403;

[0032] The auxiliary groove 403 and the auxiliary block 601 are used in combination, so that the slide plate 6 moves more smoothly in the slide groove 402. When the spring 5 pushes the slide plate 6, the auxiliary block 601 slides along the auxiliary groove 403, ensuring that the slide plate 6 always moves along the predetermined track, avoiding movement deviation caused by vibration or uneven force, and achieving a better auxiliary effect.

[0033] A positioning groove 102 is provided on the outer surface of the moving cone 1, and a positioning block 10 is provided on one side of the lining plate 2. The positioning block 10 is installed in the positioning groove 102.

[0034] By using the positioning block 10 in conjunction with the positioning groove 102, the liner 2 can be quickly and accurately aligned with the moving cone 1 during installation. At the same time, the positioning block 10 and the positioning groove 102 cooperate to increase the contact area between the liner 2 and the moving cone 1, thereby dispersing the force on the liner 2 during operation.

[0035] When installing the liner 2, first align the positioning block 10 on the liner 2 with the positioning groove 102 on the outer surface of the moving cone 1. The shape and size of the positioning block 10 match the positioning groove 102 to ensure that the positioning block 10 can be smoothly inserted into the positioning groove 102. When the positioning block 10 is inserted into the positioning groove 102, the outer surface of the positioning block 10 is in close contact with the inner surface of the positioning groove 102 to form a preliminary positioning. The insertion depth of the positioning block 10 is determined by the length of the positioning groove 102 and the length of the positioning block 10 to ensure that the relative position of the liner 2 and the moving cone 1 is accurate. When the positioning block 10 is fully inserted into the positioning groove 102, the positioning block 10 is inserted into the positioning groove 102. After the positioning groove 102 is inserted, the position of the liner 2 is initially fixed. At this time, the connecting block 4 is also inserted into the installation groove 101 of the moving cone 1, and the position of the liner 2 is further fixed by the cooperation of the limiting block 8 and the limiting groove 301. During the operation of the cone crusher, the moving cone 1 will rotate or swing. Due to the close cooperation between the positioning block 10 and the positioning groove 102, the liner 2 will move with the moving cone 1 to maintain the stability of the relative position. The movement of the positioning block 10 in the positioning groove 102 is mainly sliding along the length direction of the positioning groove 102 to ensure that the liner 2 will not deviate or loosen.

[0036] A plurality of crushing grooves 201 are provided on the other side of the liner 2;

[0037] The crushing groove 201 provided can increase the contact area between the material and the liner 2, making the material easier to be crushed, thereby improving the overall crushing effect of the equipment. At the same time, during the crushing process, the material has a greater impact force on the liner 2, and the crushing groove 201 can disperse the impact force to multiple grooves, thereby avoiding excessive wear of the liner 2 locally and extending the service life of the liner 2. The crushing groove 201 is designed as a plurality of groove structures distributed on the working surface of the liner 2. These grooves increase the contact area between the liner 2 and the material, so that the material can be more evenly distributed on the surface of the liner 2 during the crushing process, avoiding local stress concentration. A larger contact area means that more materials can be affected by the crushing force at the same time, thereby improving the crushing efficiency and crushing. The shape and arrangement direction of the groove 201 match the movement direction of the moving cone 1. When the material enters the crushing chamber, the crushing groove 201 can effectively guide the material to flow to the crushing area between the moving cone 1 and the liner 2 to prevent the material from sliding or accumulating on the surface of the liner 2. This guiding effect ensures that the material can quickly enter the crushing area, reduce ineffective movement, and improve crushing efficiency. The design of the crushing groove 201 allows the material to be subjected to multi-directional extrusion and shear forces during the crushing process. When the material enters the crushing groove 201, the groove wall will exert lateral force on the material, and the movement of the moving cone 1 will exert positive pressure on the material. This multi-directional force distribution makes the material more likely to break and crush, especially when processing materials with higher hardness.
