[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] A cone crusher, such as Figures 1 to 5 As shown, it includes a body 1 and a movable cone liner 2 and a fixed cone liner 3 installed in the body 1. The fixed cone liner 3 includes two symmetrically arranged semi-fixed cone plates 4. The two semi-fixed cone plates 4 fit together and are detachably connected to the inner wall of the body 1. The movable cone liner 2 includes two symmetrically arranged semi-movable cone plates 5. The semi-movable cone plates 5 are fan-shaped arc plates. The two semi-movable cone plates 5 are detachably connected to each other in a frustum shape. When the two semi-movable cone plates 5 are installed together, they form a frustum shape. The semi-fixed cone plates 4 and the semi-movable cone plates 5 are both made of high manganese steel. The horizontal height of the bottom of the semi-movable cone plate 5 is less than the horizontal height of the bottom of the semi-fixed cone plate 4. A crushing chamber 6 is formed between the bottom of the semi-fixed cone plate 4 and the bottom of the semi-movable cone plate 5. One of the semi-movable cone plates 5 has a A trapezoidal protrusion 7 is welded on the top, and the number of trapezoidal protrusions 7 is two. A slot 8 for the trapezoidal protrusion 7 to be inserted is provided on the top of the other semi-movable cone plate 5. The trapezoidal protrusion 7 is fixedly installed in the slot 8 by a bolt 9. A threaded hole 1 for installing the bolt 9 is provided on the bottom wall of the trapezoidal protrusion 7 and the slot 8. A plurality of embedded grooves 15 are provided on the top inner wall of the semi-fixed cone plate 4. The plurality of embedded grooves 15 are distributed in a ring shape on the inner wall of the semi-fixed cone plate 4. An accommodating chamber 16 is formed between the top of the semi-fixed cone plate 4 and the top of the semi-movable cone plate 5. The width of the accommodating chamber 16 is greater than the width of the crushing chamber 6. The semi-fixed cone plate 4 is installed on the inner wall of the body 1 by fastening bolts 17. Screw holes for installing the fastening bolts 17 are provided on the semi-fixed cone plate 4 and the body 1.

[0022] When the machine body 1 is in normal use, the two semi-fixed cone plates 4 are connected to the screw holes on the semi-fixed cone plates 4 and the machine body 1 through the fastening bolts 17, so that one end of the fastening bolts 17 is respectively connected to the screw holes on the semi-fixed cone plates 4 and the machine body 1. At this time, the two semi-fixed cone plates 4 conflict with each other, and the semi-fixed cone plates 4 can be stably installed inside the machine body 1, and the trapezoidal protrusion 7 on the top of one semi-movable cone plate 5 is embedded in the groove 8 on the top of the other semi-movable cone plate 5, and is connected to the threaded hole 1 in the trapezoidal protrusion 7 and the bottom wall of the groove 8 through bolt 1. At this time, the two semi-movable cone plates 5 are installed to each other in a truncated cone shape, and the trapezoidal protrusion 7 is snapped into the groove 8 to prevent the two semi-movable cone plates 5 from shifting in the horizontal direction, thereby improving the stability of the two semi-movable cone plates 5 when spliced ​​together. After that, when the ore is poured into the machine body 1 for crushing, the movable cone liner 2 is driven by the motor to be fixed on the machine body. 1 rotates, at this time the ore will first enter the accommodating chamber 16 formed between the top of the semi-fixed cone plate 4 and the top of the semi-movable cone plate 5, and the ore will be crushed under the impact and extrusion of the movable cone liner 2 and the fixed cone liner 3 through the high-speed movement of the movable cone liner 2. Due to the presence of multiple embedded grooves 15, the ore on the top of the semi-fixed cone plate 4 and the top of the semi-movable cone plate 5 will be abutted at the notch of the embedded groove 15, and then the ore abutting at the notch of the embedded groove 15 will be crushed by the rotation of the movable cone liner 2, so that the ore can be preliminarily crushed in the accommodating chamber 16, and then the ore will enter the crushing chamber 6 formed between the bottom of the semi-fixed cone plate 4 and the bottom of the semi-movable cone plate 5 for further crushing, which can improve the crushing efficiency. High manganese steel has good wear resistance, which can reduce the wear of the ore on the inner wall of the fixed cone liner 3 and the outer wall of the movable cone liner 2.

[0023] When local wear occurs on the inner wall of the fixed cone liner 3 close to the movable cone liner 2, one of the semi-fixed cone plates 4 with the worn part is removed. At this time, the fastening bolts 17 are removed to separate them from the screw holes on the semi-fixed cone plate 4 and the body 1 respectively. Then, the worn semi-fixed cone plate 4 is removed and replaced from the body 1 without replacing the entire fixed cone liner 3. The unworn semi-fixed cone plate 4 can continue to be used. When local wear occurs on the outer wall of the movable cone liner 2 close to the fixed cone liner 3, first remove the bolt 19 to separate it from the inside of the trapezoidal protrusion 7 and the threaded hole 1 on the bottom wall of the slot 8 respectively, and then slide the semi-movable cone plate 5 with the trapezoidal protrusion 7 upward to drive the trapezoidal protrusion 7 to move upward. , until the trapezoidal protrusion 7 is out of the slot 8, the disassembly between the two half movable cone plates 5 can be completed. After that, by replacing one of the half movable cone plates 5 with the worn part, there is no need to replace the entire movable cone lining 2, and the unworn half movable cone plate 5 can continue to be used. Therefore, in the process of the fixed cone lining 3 and the movable cone lining 2 crushing the ore, when the inner wall of the fixed cone lining 3 or the outer wall of the movable cone lining 2 has local wear that affects the crushing effect of the ore, at this time, by disassembling one of the half fixed cone plates 4 or one of the half movable cone plates 5 with the worn part, there is no need to replace the entire fixed cone lining 3 or the movable cone lining 2, thereby saving the cost of replacing the entire fixed cone lining 3 or the movable cone lining 2.

[0024] The outer walls of the two semi-movable cone plates 5 are detachably connected with multiple mounting strips 10. The multiple mounting strips 10 are equidistantly arranged on the outer wall of the semi-movable cone plate 5. The mounting strips 10 fit the outer wall of the semi-movable cone plate 5. A plurality of protrusions 11 arranged at intervals are welded on the side of the mounting strip 10 close to the semi-fixed cone plate 4. The protrusions 11 are hemispherical. A plurality of mounting grooves 12 are provided on the top of the semi-movable cone plate 5. A mounting block 13 for snapping into the mounting groove 12 is welded on the top of the mounting strip 10. The mounting block 13 is fixedly installed in the mounting groove 12 by a second bolt 14. A threaded hole 2 for connecting with the second bolt 14 is provided inside the mounting block 13 and on the inner bottom wall of the mounting groove 12.

[0025] When the movable cone liner 2 is used, the mounting block 13 is first inserted into the mounting groove 12. At this time, the second threaded hole on the mounting block 13 corresponds to the second threaded hole on the inner bottom wall of the mounting groove 12, and the side of the mounting strip 10 away from the protrusion 11 is fitted with the outer wall of the semi-movable cone plate 5. Then, the second bolt 14 is used to connect the mounting block 13 and the second threaded hole on the inner bottom wall of the mounting groove 12, respectively, so that the mounting strip 10 is stably installed on the semi-movable cone plate 5. At this time, the protrusion 11 is set toward the semi-fixed cone plate 4, so that when the ore enters the crushing chamber 6 formed between the bottom of the semi-fixed cone plate 4 and the bottom of the semi-movable cone plate 5 for crushing, By the protrusion 11 contacting with the ore and the protrusion 11 participating in the crushing process, the crushing of the ore is not completed by the movable cone liner 2 itself, which can reduce the participation rate of the movable cone liner 2 and the wear of the movable cone liner 2. When only the protrusion 11 is worn and needs to be disassembled and replaced, the second bolt 14 is removed to separate it from the mounting block 13 and the second threaded hole on the bottom wall of the mounting groove 12 respectively, and then the mounting block 13 is removed upward to separate it from the mounting groove 12, and the mounting strip 10 is not in contact with the outer wall of the semi-movable cone plate 5. Then the worn protrusion 11 and the mounting strip 10 are removed and replaced from the semi-movable cone plate 5.
