Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and more specifically, to a cone crusher. Background Technology

[0002] Currently, the traditional crushing process for minerals such as pyrophyllite generally employs a two-stage crushing method. First, the raw ore is initially crushed using a large crusher. Then, the crushed material is transferred by a loader to a smaller crusher for secondary crushing to achieve the desired particle size. This process is widely used in mineral processing, and its main advantage is its ability to handle larger-sized raw ores. Through staged crushing, it ensures the consistency and applicability of the final product's particle size.

[0003] However, in existing technologies, the small crushers in two-stage crushing processes are relatively inefficient and have limited crushing force, making it difficult to handle ores with different hardness and particle sizes. Especially when processing ores with high hardness or large particle sizes, multiple crushing operations are often required, which not only increases energy consumption but also prolongs the production cycle and reduces overall production efficiency. Secondly, the material crushed by the small crusher needs to be transferred again by a loader. This step not only increases production costs but may also lead to secondary contamination or loss of material due to improper loader operation, affecting product quality. Furthermore, the transitions between processes in the entire crushing process are not smooth enough, resulting in excessively long material storage time in the silo, affecting the continuity of subsequent processes and reducing the overall efficiency of the production line.

[0012] Furthermore, the extrusion assembly also includes: a mounting base disposed within the machine body, wherein a portion of the camshaft is rotatably disposed within the mounting base; and a second drive component, wherein one end of the transmission component away from the second bevel gear extends out of the machine body and is connected to the drive end of the drive component, so that the drive component drives the cone crusher to rotate and yaw during the rotation.

[0013] Furthermore, a hemispherical groove is provided on the end of the camshaft section facing the cone crusher, and a sliding protrusion is provided inside the cone crusher, with at least a portion of the sliding protrusion slidingly connected to the hemispherical groove.

[0016] This application, by tilting the axis of the cone crusher to the axis of rotation, and in conjunction with the rotational motion of the cone crusher, can create lateral compression of the material entering the extrusion channel from the feed inlet, providing more precise extrusion crushing force. Compared to traditional mixing crushing methods, the crushing process is more efficient and can better adapt to the crushing needs of materials with different hardness and particle size. This solves the technical problem in existing technologies where crushers struggle to crush materials of different particle sizes, and the crushing force is relatively small, requiring multiple crushing operations, leading to complex processes. Simultaneously, the adjustability of the blocking component relative to the cone crusher allows the operator to flexibly adjust the opening size of the extrusion channel according to actual needs, further optimizing the crushing effect and improving crushing efficiency.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To address the technical problem that existing crushers struggle to crush materials of different sizes and require multiple crushing operations due to their relatively low crushing force, resulting in complex processes, this utility model provides a cone crusher.

[0028] Please refer to Figures 1 to 3 As shown, the present invention provides a cone crusher, including a body 10, a blocking assembly 20, and a compression assembly 30. The body 10 has a crushing chamber 11 for receiving materials and a feed inlet 12 and a discharge outlet 13 communicating with the crushing chamber 11. The blocking assembly 20 is disposed in the crushing chamber 11 near the feed inlet 12, and the blocking assembly 20 includes a cylindrical blocking member 21. The compression assembly 30 is disposed in the crushing chamber 11 and includes a rotatably disposed cone crushing head 31. At least a portion of the cone crushing head 31 is located within the blocking member 21 and forms a compression channel 32 communicating with the feed inlet 12 between the cone crushing head 31 and the blocking member 21, so as to crush the material flowing into the compression channel 32 from the feed inlet 12 through the cone crushing head 31. The position of at least a portion of the blocking member 21 relative to the cone crushing head 31 is adjustable to control the opening size of the compression channel 32. The axis of the cone crushing head 31 is inclined to the axis of the blocking member 21.

[0029] By adopting the technical solution of this embodiment, by tilting the axis of the cone crusher 31 to the axis of rotation, and in conjunction with the rotational movement of the cone crusher 31, the material entering the extrusion channel 32 from the feed inlet 12 can be subjected to lateral extrusion, providing more precise extrusion crushing force. Compared with the traditional stirring crushing method, the crushing process is more efficient and can better adapt to the crushing needs of materials with different hardness and particle size. This solves the technical problem in the prior art that the crusher is difficult to crush materials of different particle sizes and has a small crushing force, requiring multiple crushing operations, resulting in complex processes. At the same time, the adjustability of the position of the blocking component 21 relative to the cone crusher 31 allows the operator to flexibly adjust the opening size of the extrusion channel 32 according to actual needs, further optimizing the crushing effect and improving crushing efficiency.

[0030] As can be seen, the new cone crusher of this application, with its stronger, more flexible, and higher crushing capacity, moves the secondary crushing process forward and connects it directly to the material conveying line after primary crushing, thus eliminating the intermediate short-haul loader link and forming a continuous production line from raw ore entering the plant to the crushed feed hopper. Furthermore, the improved left-right extrusion crushing method, compared to the original stirring crushing, can more effectively handle materials of different particle sizes and hardness, achieving one-time crushing to the required particle size, simplifying the crushing process. Moreover, by flexibly adjusting the opening size of the extrusion channel 32 according to different actual needs, production efficiency is improved, production costs are reduced, and material loss and contamination during production are minimized, thereby improving product quality.

[0031] Specifically, the diameter of the cone crusher head 31 gradually increases along the direction from the feed inlet 12 to the discharge outlet 13, and the blocking component 21 is a conical cylinder with a diameter that gradually decreases along the direction from the feed inlet 12 to the discharge outlet 13. The blocking component 21 includes a first blocking member 210 and a second blocking member 211, which are arranged at a first set angle A1. The first blocking member 210 is located on the side of the second blocking member 211 away from the feed inlet 12 and forms a first channel section 320 between it and the cone crusher head 31. The second blocking member 211 and the cone crusher head 31 form a second channel section 321 that communicates with the first channel section 320. The cross-sectional area of ​​the second channel section 321 gradually decreases along the direction from the feed inlet 12 to the discharge outlet 13.

[0032] Through the cooperation between the blocking component 21 and the cone crusher head 31, after the material enters the crushing chamber 11, it is first pre-crushed through the second channel section 321 with a gradually decreasing opening, and then enters the first channel section 320 for lateral compression crushing. This allows the material to transition more smoothly to the next crushing stage during the crushing process, reducing the stagnation time of the material in the crushing chamber 11. This process not only improves the material handling capacity and the production efficiency of the crusher, but also achieves preliminary classification of the crushed particle size, ensuring a more uniform output particle size. Furthermore, it makes the crushing force on the material more evenly distributed in different channel stages, avoiding local overload and improving the stability and durability of the equipment. Therefore, by optimizing the setting of the cone crusher head 31 and the structure of the blocking component 21, efficient crushing, classification, smooth flow, and low energy consumption of the material are achieved, while improving the stability and ease of operation of the equipment.

[0033] In this embodiment, the blocking component 21 further includes a third blocking component 212, which is disposed on the side of the second blocking component 211 away from the first blocking component 210 and is movably connected to the second blocking component 211. The third blocking component 212 is disposed at a second set angle A2 with the second blocking component 211. The third blocking component 212 and the cone crusher 31 form a third channel section 322 that communicates with the second channel section 321 and the feed inlet 12. By adjusting the position of the third blocking component 212 relative to the cone crusher 31, materials of different particle sizes can enter from the feed inlet 12 through the third channel section 322 into the second channel section 321 and the first channel section 320 for compression and crushing.

[0034] The above setup, by adjusting the position of the third blocking element 212 relative to the cone crusher head 31, guides materials of different particle sizes into the second channel section 321 for compression crushing, and then into the subsequent first channel section 320 for finer compression crushing. This design helps optimize the crushing sequence of the material flow, achieves more accurate particle size classification, and improves crushing efficiency and product quality. The adjustability of the third blocking element 212 allows the operator to dynamically adjust the opening of the crushing channel and the crushing force according to the processing requirements of materials of different particle sizes, thereby better controlling the entire crushing process. This flexibility can not only handle the crushing of various materials, but also be adjusted in real time according to production needs to ensure that the crushing effect meets specific requirements.

[0035] As can be seen, by using a staged crushing method, the need for all materials to undergo high-intensity crushing is avoided, thus reducing the overall energy consumption in the crushing process. Materials with smaller particle sizes can be directly processed through the first channel section 320, while materials with larger particle sizes can be pre-crushed through the third channel section 322 and the second channel section 321. This targeted crushing strategy not only saves energy but also improves the economic efficiency of the equipment.

[0036] In this embodiment, the blocking assembly 20 further includes: a driving structure 40 disposed on the inner wall of the body 10; the driving end of the driving structure 40 is connected to the third blocking member 212; an annular connecting rod 22 is disposed circumferentially on the end of the second blocking member 211 facing the third blocking member 212; and multiple connecting collars 23 are disposed on the end of the third blocking member 212 facing the second blocking member 211. The multiple connecting collars 23 are sleeved on the annular connecting rod 22 to drive the third blocking member 212 to adjust its position relative to the cone crusher head 31 via the driving structure 40. The end of the second blocking member 211 facing the first blocking member 210 is provided with an annular U-shaped groove; the annular connecting rod 22 is disposed within the U-shaped groove and connected to the bottom wall of the U-shaped groove via multiple connecting rods; and the multiple connecting collars 23 are sleeved on the annular connecting rod 22 and disposed to avoid the connecting rods.

[0037] The drive structure 40 enables automatic fine-tuning of the position of the third blocking component 212. When the opening of the third channel section 322 needs adjustment, the drive structure 40 responds quickly without manual intervention, greatly improving the automation level of the equipment. This automatic adjustment function, combined with a precise control system, enables precise control of the crushing channel size, thereby adjusting the optimal crushing conditions in real time according to different material particle sizes and hardness characteristics, improving crushing efficiency and product quality. Furthermore, the coordinated design of the annular connecting rod 22 and multiple connecting collars 23 not only enhances the connection stability between the third blocking component 212 and the second blocking component 211, but also improves the wear resistance of the connection parts by dispersing stress, extending the service life of the blocking assembly 20 and reducing equipment maintenance frequency and costs.

[0038] Specifically, the drive structure 40 includes: a mounting block 41, disposed on the inner wall of the machine body 10; a telescopic rod 42, one end of which is disposed on the inner wall of the machine body 10 and connected to the drive end of the first drive component, and the other end of which is connected to the outer peripheral wall of the third blocking member 212 via a connecting block 43; a first mating member 44 is disposed on the mounting block 41, and a second mating member 45 is disposed on the connecting block 43; the first mating member 44 and the second mating member 45 are connected to each other to guide the movement of the third blocking member 212 driven by the connecting block 43 in the direction of approaching or moving away from the cone crusher head 31; wherein, one of the first mating member 44 and the second mating member 45 is a mounting protrusion, and the other of the first mating member 44 and the second mating member 45 is a mounting groove. The first drive component is a cylinder.

[0039] One end of the telescopic rod 42 is fixed to the inner wall of the machine body 10, and the other end is connected to the third blocking member 212 through the connecting block 43. The first mating member 44 on the mounting block 41 and the second mating member 45 on the connecting block 43 cooperate with each other to form a guiding mechanism. This guiding design ensures that the third blocking member 212 can move smoothly and accurately in the direction of approaching or moving away from the cone crusher head 31 when adjusting its position, avoiding deviation and shaking during the movement, and ensuring the stability of the internal structure of the crushing chamber 11 and the continuity of the crushing process. Through the direct connection between the telescopic rod 42 and the first driving component, as well as the efficient linkage with the third blocking member 212, the driving structure 40 can quickly respond to the control signal and quickly adjust the position of the third blocking member 212. This can significantly reduce the adjustment time and improve production efficiency. At the same time, the first mating member 44 and the second mating member 45 are connected by a protrusion and groove, which not only simplifies the assembly process between components, but also enhances the reliability of the connection and the overall strength of the structure. It can effectively disperse the stress at the connection point, prevent the components from being damaged due to stress concentration during long-term, high-intensity crushing operations, and extend the service life of the equipment.

[0040] In this embodiment, the first set angle A1 satisfies: 165°≤A1≤170°, and the second set angle A2 satisfies: 160≤A2≤165°. The first set angle A1 is greater than the second set angle A2.

[0041] The specific angular ranges of the first set angle A1 and the second set angle A2 are designed to optimize the flow path and crushing force distribution of the material within the extrusion channel 32. The design range of the first set angle A1 allows the material to adapt to changes in particle size as it transitions from the second channel section 321 to the first channel section 320 after crushing. It also facilitates a gradual increase in crushing force during the crushing process to meet the crushing requirements of materials with different particle sizes. The design range of the second set angle A2 is flexibly fine-tuned by the third blocking element 212 to adapt to the actual needs of materials with different particle sizes. For initial materials with significantly smaller particle sizes, the second set angle A2 can be fine-tuned to a smaller value to accommodate materials of that size. Furthermore, when this initial material enters the third channel section 322, it can undergo a certain degree of pre-crushing treatment, enhancing the flexibility and adaptability of the equipment.

[0042] In this embodiment, the first blocking member 210 and the second blocking member 211 are integrally formed, and at least a portion of the third blocking member 212 is made of a plastic material. This configuration, by integrating the first and second blocking members 210 and 211, enhances the structural strength of the blocking assembly 20, reduces the number of connection points between components, thereby lowering the failure rate due to loose connections or wear, and extending the service life of the blocking assembly 20. It also simplifies the assembly process and reduces manufacturing and maintenance costs. The portion of the third blocking member 212 is made of a plastic material, which possesses good plasticity and wear resistance. The use of this plastic material allows for flexible fine-tuning of the third blocking member 212 when adjusted by the drive structure 40, reducing frictional resistance during adjustment. Simultaneously, the wear resistance of the plastic material ensures that the shape and size of the third blocking member 212 do not change significantly over long-term use, maintaining the stability of the third channel section 322 and improving the operating efficiency of the equipment.

[0043] It can be seen that by precisely setting the angle range between the first set angle A1 and the second set angle A2, and by designing the plastic material of the third blocking member 212, the cone crusher can more precisely control the crushing process. It is not only suitable for processing materials of different particle sizes, but also can efficiently crush materials with smaller particle sizes or lower hardness, thus enhancing the equipment's adaptability to different material types and particle sizes.

[0044] In this embodiment, the extrusion assembly 30 further includes: a camshaft 33, rotatably disposed in the crushing chamber 11, the cone crushing head 31 being coaxially connected to the cam of the camshaft 33, and a first bevel gear 34 disposed at one end of the cam of the camshaft 33; and a transmission member 35, rotatably disposed, with a second bevel gear 36 disposed at one end of the transmission member 35, the second bevel gear 36 meshing with the first bevel gear 34, so that the transmission member 35 drives the cone crushing head 31 to rotate and oscillate during the rotation.

[0045] The cone crusher 31 is coaxially connected to the cam on the camshaft 33, and a first bevel gear 34 and a second bevel gear 36 meshing with it achieve a compound motion mode for the cone crusher 31. The cone crusher 31 not only rotates with the camshaft 33, but also oscillates during rotation to squeeze the material in the extrusion channel 32 from side to side. This compound motion mode greatly increases the contact area and crushing force diversity between the cone crusher 31 and the material, thereby improving crushing efficiency and allowing the material to be fully crushed in a short time. Furthermore, the combined rotation and oscillation motion helps optimize the flow of material in the extrusion channel 32. As the cone crusher 31 oscillates, the material is pushed to different positions on the crushing surface, increasing the chance of contact between the material and the blocking component 21, further improving the uniformity and effectiveness of crushing. Simultaneously, this compound motion also helps prevent excessive accumulation of material in a certain area, reducing the risk of blockage.

[0046] Compared to traditional crusher designs, this composite motion mechanism based on camshaft 33 and bevel gears simplifies the transmission structure, reduces intermediate transmission links, and lowers the complexity of the equipment. At the same time, the combination of cam and bevel gears makes maintenance and replacement easier, reducing the difficulty and cost of equipment maintenance.

[0047] Specifically, the extrusion assembly 30 further includes: a mounting base 37 disposed within the machine body 10, with a portion of the camshaft 33 rotatably disposed within the mounting base 37; and a second drive component 38, with one end of the transmission member 35 extending away from the second bevel gear 36 and connecting to the drive end of the drive component outside the machine body 10, so that the drive component drives the cone crusher head 31 to rotate and yaw during rotation. The second drive component 38 is a motor.

[0048] The mounting base 37 provides a stable fulcrum for the camshaft 33, ensuring its stability during high-speed rotation and when driving the cone crusher head 31 in yaw motion. The mounting base 37 suppresses radial displacement of the camshaft 33, reducing vibration and thus improving the accuracy of the cone crusher head 31's motion trajectory, ensuring efficient and stable crushing. The second drive component 38 is connected to the cone crusher head 31 via the transmission component 35. This direct power transmission method reduces energy loss in intermediate stages and improves power transmission efficiency. Furthermore, by placing a portion of the camshaft 33 within the mounting base 37, the spatial layout of the crushing chamber 11 can be optimized, making its internal structure more compact. This not only improves the space utilization of the crusher but may also increase the capacity of the crushing chamber 11, thereby increasing the mineral processing capacity per unit time.

[0049] As can be seen, through the cooperation of the mounting base 37 and the second drive component 38, the extrusion assembly 30 of the cone crusher can achieve a more stable and efficient compound motion, which not only improves the crushing efficiency and equipment reliability, but also optimizes the structural design of the crushing chamber 11, simplifies the maintenance process, and enhances the adaptability and flexibility of the equipment to different crushing tasks.

[0050] Specifically, a hemispherical groove 330 is provided on the end of the camshaft 33 facing the cone crusher 31, and a sliding protrusion 310 is provided inside the cone crusher 31, at least a portion of the sliding protrusion 310 being slidably connected to the hemispherical groove 330.

[0051] Through the sliding connection between the sliding protrusion 310 and the hemispherical groove 330, the cone crusher 31 can oscillate under the guidance of the hemispherical groove 330 according to the rotation of the camshaft 33. This motion mode ensures that the cone crusher 31 can stably and accurately perform left and right oscillation movements during the crushing process, effectively increasing the contact area between the cone crusher 31 and the crushed material and the direction of the crushing force, thereby improving crushing efficiency and the uniformity of crushing effect. At the same time, the relatively large contact surface between the hemispherical groove 330 and the sliding protrusion 310 can disperse pressure and reduce local wear. Furthermore, compared with other forms of connection (such as rigid connection or hinge), the sliding connection can reduce the impact force between components, thereby extending the service life of the cone crusher 31 and the camshaft 33 and reducing maintenance costs.

[0052] Compared to complex mechanical connections, the combination of the hemispherical groove 330 and the sliding protrusion 310 simplifies the connection structure between the cone crusher head 31 and the camshaft 33, making the assembly and maintenance of the equipment much easier. When the crusher head needs to be adjusted or replaced, only the corresponding fixing device needs to be loosened, without disassembling the entire crusher, saving maintenance time and costs.

[0053] In this embodiment, the axis of the cone crusher 31 and the axis of the blocking component 21 have a third set angle A3, which satisfies: 1°≤A3≤3°.

[0054] The third setting of the included angle A3 allows the cone crusher head 31 to form a dynamically changing crushing and extrusion channel 32 with the blocking component 21 during rotation and yaw motion. The angle range of 1° to 3° ensures the uniform distribution of crushing force within the crushing chamber 11, avoiding local overheating or excessive wear, and improving crushing efficiency and product quality.

[0055] In this embodiment, the outer peripheral wall of the cone crusher 31 and the inner peripheral wall of the blocking component 21 have a maximum distance L1 and a minimum distance L2, which satisfy the following conditions: 15mm≤L2≤20mm, 8mm≤L2≤12mm.

[0056] The minimum spacing L2 is set within a range of 8mm to 12mm, and the maximum spacing L1 is set within a range of 15mm to 20mm. This precise spacing control effectively adjusts the size of the dynamic extrusion channel 32, thereby controlling the particle size of the crushed material and improving the equipment's adaptability and flexibility to different crushing needs. By setting reasonable L1 and L2 spacing ranges, unnecessary friction and energy consumption during the crushing process can be reduced. In particular, the fine control of the L2 spacing helps to accurately control the crushing force of the cone crusher head 31, thereby improving the energy efficiency ratio of the crushing process and reducing overall energy consumption.

[0057] It can be seen that by setting the third set angle A3 and the spacing L1 and L2 between the cone crusher head 31 and the blocking component 21, the cone crusher can achieve more efficient and finer material crushing, while reducing energy consumption, extending the service life of the equipment, and improving the controllability and stability of the crushing process.

[0058] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0059] The cone crusher includes a body 10, a blocking assembly 20, and a compression assembly 30. The body 10 has a crushing chamber 11 for receiving materials and a feed inlet 12 and a discharge outlet 13 communicating with the crushing chamber 11. The blocking assembly 20 is disposed in the crushing chamber 11 near the feed inlet 12 and includes a cylindrical blocking member 21. The compression assembly 30 is disposed in the crushing chamber 11 and includes a rotatably disposed cone crushing head 31. At least a portion of the cone crushing head 31 is located within the blocking member 21 and forms a compression channel 32 communicating with the feed inlet 12 between the cone crushing head 31 and the blocking member 21, so as to crush the material flowing into the compression channel 32 from the feed inlet 12 through the cone crushing head 31. At least a portion of the blocking member 21 is adjustablely positioned relative to the cone crushing head 31 to control the opening size of the compression channel 32. The axis of the cone crushing head 31 is inclined to the axis of the blocking member 21. This application, by tilting the axis of the cone crusher 31 to the axis of rotation, and in conjunction with the rotational motion of the cone crusher 31, can create lateral compression of the material entering the extrusion channel 32 from the feed inlet 12, providing more precise extrusion crushing force. Compared with traditional stirring crushing methods, the crushing process is more efficient and can better adapt to the crushing needs of materials with different hardness and particle size. This solves the technical problem in the prior art where crushers are unable to crush materials of different particle sizes and the crushing force is relatively small, requiring multiple crushing operations, resulting in complex processes. At the same time, the adjustability of the position of the blocking component 21 relative to the cone crusher 31 allows the operator to flexibly adjust the opening size of the extrusion channel 32 according to actual needs, further optimizing the crushing effect and improving crushing efficiency.
