[0018] The utility model discloses a cold-mounted carbide cone crusher wear-resistant lining plate, such as Figure 1-6 As shown, it includes a liner base 1, which is cone-shaped as a whole. To facilitate installation on the crusher, a plug hole 2 is provided on the upper part of the liner base 1, and a circumferentially arranged block 3 is provided on the lower part of the liner base 1. The setting of the plug hole 2 and the block 3 can provide a positioning reference for the installation of the liner on the rotating shaft.

[0019] In order to improve the overall strength and service life of the liner, a plurality of circumferentially arranged insertion grooves 4 are provided on the outer periphery of the liner base 1 between the insertion hole 2 and the block 3. A cemented carbide block is installed in each insertion groove 4. The strength and wear resistance of the cemented carbide block are better than those of the material of the liner base 1. At the same time, the liner at the position of the cemented carbide block is the main working area for extrusion and grinding with the cylinder.

[0020] The cemented carbide block includes a first column 5 matched with the insertion slot 4, and a second column 6 is provided at the end of the first column 5 extending out of the insertion slot 4, and the diameter of the second column 6 is smaller than that of the first column 5. A plurality of circumferentially arranged limiting pressure plates 7 are also provided on the outer periphery of the liner base 1, and each limiting pressure plate 7 is provided with a through hole 8 matched with the second column 6, and a hemispherical wear-resistant block 9 is provided at the end of the second column 6 extending out of the through hole 8. Due to the difference in diameter between the second column 6 and the first column 5, the limiting pressure plate 7 limits the first column 5 in the insertion slot 4, while the second column 6 and the hemispherical wear-resistant block 9 at the end can extend out of the limiting pressure plate 7, and the hemispherical wear-resistant block 9 is used to achieve extrusion and grinding of the material.

[0021] In order to realize the detachable installation of the limiting pressure plate 7 on the lining base 1, connecting plates 10 are arranged on the upper and lower sides of the limiting pressure plate 7, and a first bolt 11 is installed on the connecting plate 10. A threaded hole matching the first bolt 11 is opened on the lining base 1. By tightening the first bolt 11 in the threaded hole, the limiting pressure plate 7 can be fixedly installed on the lining base 1. At the same time, each limiting pressure plate 7 is also positioned and installed in the insertion groove 4 with the carbide block, thereby realizing the cold insertion installation of the carbide block on the lining.

[0022] The materials are ground and extruded by carbide blocks with higher strength and better wear resistance. At the same time, each carbide block can be disassembled and replaced individually. Compared with the traditional one-piece cast liner that needs to be replaced as a whole after damage, the use and repair costs of the liner with this structure are greatly reduced, and the strength of the liner is also effectively improved.

[0023] When the liner rotates eccentrically and squeezes and crushes the material between the cylinder, there is a situation where the harder material cannot be crushed and enters the extrusion gap to jam the liner, which will seriously affect the service life of the liner. In order to solve the above problem and reduce the jamming of the liner during use, an elastic steel plate 12 is installed in the insertion slot 4. The elastic steel plate 12 is located at the bottom of the first column 5. The elastic steel plate 12 always has the tendency to squeeze the first column 5 inside the limit pressure plate 7. When there is a larger and harder material that cannot be crushed, the material can push the carbide block to overcome the elastic force of the elastic steel plate 12 and move a short distance to ensure that the material can fall smoothly, minimizing the jamming of the liner, wherein the thrust of the elastic steel plate 12 on the carbide block and the elastic floating of the carbide block will not affect the normal extrusion and crushing operation of the material.

[0024] Furthermore, in order to increase the contact and extrusion area between the material and improve the crushing efficiency of the material, such as Fig. 9 As shown, the hemispherical wear-resistant block 9 is provided with a plurality of circumferentially arranged protrusions 13 .

[0025] The limiting pressure plate 7 is fixedly mounted on the liner base 1 by the first bolt 11. When the liner rotates, the first bolt 11 may rotate and loosen due to its own inertia and reciprocating vibration, and the limiting pressure plate 7 cannot stably limit the carbide block.

[0026] In order to make each limiting pressure plate 7 more firmly arranged on the lining plate base 1, as Figure 7 and Figure 8 As shown, corresponding to the connecting plate 10 on the upper side of all the limiting pressure plates 7, two detachable first semicircular snap rings 14 are installed on the outer periphery of the lining plate base 1, and the two first semicircular snap rings 14 are connected by a second bolt 15, and a limiting convex edge 16 is provided on the connecting plate 10 on the upper side of the limiting pressure plate 7, and the first semicircular snap ring 14 is located between the limiting convex edge 16 and the limiting pressure plate 7. The limiting convex edge 16 can realize the upward movement limit of the two first semicircular snap rings 14, and the limiting pressure plate 7 can realize the downward movement limit of the two first semicircular snap rings 14, and the outer periphery of the lining plate base 1 itself has a certain slope, and after the two first semicircular snap rings 14 are fixedly connected, the upper position of all the limiting pressure plates 7 can be clamped and fixed.

[0027] Corresponding to the connecting plate 10 at the lower side of all the limiting pressure plates 7, two detachable second semicircular snap rings 17 are installed on the outer periphery of the lining plate base 1, and the two second semicircular snap rings 17 are connected by a third bolt 18, and the second semicircular snap rings 17 are located at the lower side of the limiting pressure plate 7. The limiting pressure plate 7 can realize the upward movement limit of the two second semicircular snap rings 17, and the lining plate base 1 with a gradually increasing diameter downward will realize the downward movement limit of the two second semicircular snap rings 17. After the two second semicircular snap rings 17 are fixedly connected, the lower position of all the limiting pressure plates 7 can be clamped and fixed.

[0028] The first semicircular snap ring 14 and the second semicircular snap ring 17 are both provided with avoidance grooves 19 that match the connection plate 10. The provision of the semicircular snap rings can prevent the first bolts 11 in the connection plate 10 from falling off during the liner rotation operation, and at the same time, clamp and fix each limit pressing plate 7, so that the limit pressing plate 7 can be more stably set on the liner substrate 1, which is equivalent to implementing multiple guarantees for the positioning of the cemented carbide block by the limit pressing plate 7, the first semicircular snap ring 14 and the second semicircular snap ring 17. The first semicircular snap ring 14 and the second semicircular snap ring 17 can clamp and fix multiple limit pressing plates 7, so that the limit pressing plates 7 covering the substrate form a more stable whole, ensuring the stability of each component during the subsequent extrusion and crushing operation.

[0029] Furthermore, in order to arrange the cemented carbide blocks on the periphery of the liner substrate 1 more densely, multiple groups of cemented carbide blocks can be arranged on the periphery of the liner substrate 1, so that the material to be ground can have more contact area with the cemented carbide blocks, and the insertion slots 4 of adjacent circumferential circles are arranged in an interlaced manner. To adapt to the arrangement of the above-mentioned insertion slots 4, a through hole 8 is provided in the middle position of each limiting pressure plate 7, and semicircular holes 20 are provided on both sides of the limiting pressure plate 7. The semicircular holes 20 on the limiting pressure plates 7 on both sides cooperate with each other to form holes that cooperate with the second column 6, and the positioning restriction of the cemented carbide blocks is realized through the adjacent limiting pressure plates 7.

[0030] The insertion slot 4 can be a hole for inserting the alloy block in the liner base 1 through integral casting, and the carbide block is then cold-inserted into the insertion slot 4, which can give full play to the performance of the carbide block as a wear-resistant block and avoid the problem of reducing the performance of the wear-resistant alloy block due to heating. The conical liner using cold-inserted carbide blocks has good toughness and is not easy to break. The working part of the carbide block area has ultra-high wear resistance, high fatigue resistance and impact resistance.

[0031] The hemispherical wear-resistant block 9 can be a type with a smaller diameter so that it can pass through the through hole 8 on the limit pressure plate 7. After each carbide block is placed in the insertion slot 4, the limit pressure plate 7 is connected and installed, and the carbide block is allowed to pass through the bottom of the limit pressure plate 7. Furthermore, when it is necessary to crush larger particles of material, a hemispherical wear-resistant block 9 with a larger diameter can also be used. If the diameter of the hemispherical wear-resistant block 9 exceeds the diameter of the through hole 8, it cannot be installed in the above manner. To solve the above problem, Fig. 9 As shown, a screw is arranged at the bottom of the second column 6, and a screw hole matching the screw is provided in the first column 5. The first column 5 and the second column 6 are detachably connected by threads. The first column 5 can be placed in the insertion slot 4 first, and then the limit pressure plate 7 is installed, and then the second column 6 is screwed in each through hole 8. The hard alloy block here is arranged in a split body, which can realize the stable installation of the hemispherical wear-resistant block 9 with a larger diameter. In order to facilitate the placement of the first column 5 in the matching insertion slot 4, a conical surface 21 is also provided at the bottom of the first column 5. The diameter of the bottom of the conical surface 21 is smaller than the diameter of the upper part, so as to facilitate the installation of the first column 5 to form a guide, so that it can enter the insertion slot 4 more easily.

[0032] Furthermore, in order to firmly connect the two second semicircular clamping rings 17 and prevent the third bolt 18 from falling off from the installation position, as shown in FIG. Fig.10As shown, a locking pin hole is opened at the position where the two second semicircular retaining rings 17 are connected, and a locking pin 22 is installed in the locking pin hole. A limit block 23 is set at the bottom of the locking pin 22. A screw is set at the upper end of the locking pin 22 extending out of the locking pin hole, and a locking nut 24 is installed on the screw. The locking pin 22 can pass upward from the bottom position and is installed with the locking nut 24, thereby locking the third bolt 18 on the second semicircular retaining ring 17, so that the two second semicircular retaining rings 17 are firmly clamped on the limit pressure plate 7, ensuring the normal progress of subsequent extrusion and crushing operations.
