Description

[0001] The present invention relates to the technical field of crushers, and in particular to a cone crusher for crushing ore. Background Art

[0002] In the field of ore crushing, cone crusher is an important equipment widely used. Traditional cone crusher has certain limitations in structural design, especially in the way materials enter the crushing space.

[0003] In previous technical solutions, materials usually enter the crushing space from a relatively fixed direction. This single-direction feeding method causes the material to concentrate on a certain local area of ​​the moving cone after entering the crushing chamber. With long-term continuous operation, this local area of ​​the moving cone bears most of the impact and friction, making its degree of wear much higher than other areas. This uneven wear not only shortens the service life of the moving cone, increases the frequency and cost of component replacement, but also has a negative impact on crushing efficiency and product quality.

[0004] Due to the serious local wear of the moving cone, the matching accuracy between it and the inner wall of the crushing chamber gradually decreases, resulting in uneven crushing of materials during the crushing process, which in turn affects the stability of product quality. At the same time, frequent replacement of moving cone parts requires downtime, which not only interrupts the production process and reduces production efficiency, but also consumes additional manpower, material resources and time costs, bringing many inconveniences and economic burdens to the company's production operations.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, proposes a cone crusher for crushing ore, which is used for crushing materials, including a body 1, the body 1 has a feed port 101, a discharge port 102 and a crushing chamber 103, the feed port 101 and the discharge port 102 are both connected to the crushing chamber 103; the movable cone 2 is swingably arranged in the crushing chamber 103, and the movable cone 2 and the inner wall of the crushing chamber 103 form a crushing space 201; the stirring shaft 3 is rotatably arranged relative to the body 1; a plurality of stirring rods 4 are arranged on the stirring shaft 3, and are located between the feed port 101 and the crushing space 201; after the material enters the feed port 101, the material contacts the stirring rod 4 and evenly enters the crushing space 201.

[0025] In this embodiment, in order to solve the problem in the related art that the material always enters the crushing space from a fixed direction, resulting in a high degree of wear in the local area of ​​the moving cone, a cone crusher for crushing ore is designed. The body 1 is cylindrical, and the inner surface of the crushing chamber 103 is specially treated with wear resistance to increase its service life. The moving cone 2 is installed inside the body 1 and can perform stable shaking motion in the crushing chamber 103, thereby forming an effective crushing space 201 with the inner wall of the crushing chamber 103. The stirring shaft 3 is installed on the body 1 through a bearing. The stirring rod 4 is made of high-strength wear-resistant material, and one end is connected to the stirring shaft 3 to better guide the flow of materials. When the ore material is poured into the feed port 101, the motor driving the stirring shaft 3 to rotate is started, and the stirring shaft 3 drives the stirring rod 4 to rotate, so that the material continues to roll and disperse under the action of the stirring rod 4, so as to evenly enter the crushing space 201.

[0026] The advantage is that, through the setting of the stirring shaft 3 and the stirring rod 4, the way in which the material enters the crushing space 201 is changed, so that it no longer enters from a single direction, but enters evenly distributed under the stirring effect, effectively reducing the problem of high wear in local areas of the moving cone 2 due to concentrated impact of materials, extending the service life of the moving cone 2, and at the same time improving the crushing efficiency and the stability of product quality, and reducing the downtime and cost increase caused by frequent replacement of parts due to uneven wear of the moving cone 2.

[0027] Furthermore, a plurality of stirring rods 4 are evenly distributed along the circumference of the axis of the stirring shaft 3 , and also include a mounting frame 5 , which is arranged on the side wall of the feed inlet 101 and located above the crushing space 201 , and one end of the stirring shaft 3 is rotatably arranged on the mounting frame 5 .

[0028] In this embodiment, when stirring the ore material, the mounting frame 5 can provide reliable support for the stirring shaft 3, so that the stirring rod 4 can continuously and stably stir and disperse the incoming material, ensuring that the material evenly enters the crushing space 201. The advantage is that the stirring rod 4 evenly distributed around the circumference can cover the feeding area more comprehensively, so that the stirring and dispersion effect of the material is better, and the uniformity of the material entering the crushing space 201 is improved, thereby reducing the local wear of the moving cone 2, improving the overall reliability and stability of the equipment, reducing the probability of failure of the equipment during operation, and reducing the maintenance cost and the risk of production interruption.

[0029] Furthermore, the stirring shaft 3 is rotatably and vertically slidably arranged on the mounting frame 5, one end of the stirring rod 4 is hingedly arranged on the stirring shaft 3, the stirring rod has a long hole 403, and also includes a mounting ring 6, the mounting ring 6 is rotatably arranged on the mounting frame 5, the mounting ring 6 has a connecting portion 602, and the connecting portion 602 is slidably arranged in the long hole 403.

[0030] In this embodiment, one end of the stirring rod 4 is hingedly arranged on the stirring shaft 3 through a pin shaft, and the elongated hole 403 on the stirring rod 4 is arranged along its length direction, and the inner surface of the elongated hole 403 is smooth to reduce the friction when the connecting part 602 slides. The mounting ring 6 is rotatably arranged on the mounting frame 5, and the connecting part 602 of the mounting ring 6 adopts a cylindrical pin structure, and the cylindrical pin can slide smoothly in the elongated hole 403. During the operation of the equipment, when the stirring shaft 3 rotates, since the stirring rod 4 is hinged to the stirring shaft 3 and the connecting part 602 cooperates with the mounting ring 6, the stirring rod 4 will swing within a certain range, so as to better adapt to the flow state of the material and allow the material to enter the crushing space 201 more evenly.

[0031] The advantage is that the vertical sliding of the stirring shaft 3 and the articulated swing design of the stirring rod 4 enable the stirring device to adjust the stirring posture, further improving the adaptability to the material and the stirring effect, and ensuring that the material enters the crushing space 201 evenly and smoothly. This design can more effectively prevent the material from piling up or clogging at the feed port 101, reduce the impact and damage to the equipment caused by poor material flow, and also further reduce the risk of local wear of the moving cone 2, thereby improving the working efficiency and stability of the equipment, extending the service life of the equipment, and reducing the maintenance cost and operating energy consumption of the equipment.

[0032] Furthermore, the mounting frame 5 and the mounting ring 6 are both split and respectively have a dovetail groove 501 and a dovetail protrusion 601 , and the dovetail protrusion 601 is circumferentially slidably disposed in the dovetail groove 501 .

[0033] In this embodiment, the mounting frame 5 is composed of two symmetrical half frames, each of which is processed with a dovetail groove 501. The mounting ring 6 also adopts a split structure, consisting of two half rings, each of which is provided with a dovetail protrusion 601, and the dovetail protrusion 601 cooperates with the dovetail groove 501 to ensure that the mounting ring 6 can slide and rotate steadily and smoothly on the mounting frame 5. For example, during the assembly of the equipment, the dovetail protrusion 601 of the mounting ring 6 is aligned with the dovetail groove 501 of the mounting frame 5, and the installation can be completed by gently pushing it in, and during the operation of the equipment, this split structure can be easily disassembled and maintained. When it is necessary to replace components such as the stirring shaft 3 or the stirring rod 4, it is only necessary to remove the connecting bolts of the mounting ring 6 and the mounting frame 5, and the relevant components can be taken out for repair or replacement, which greatly improves the maintenance convenience and efficiency of the equipment.

[0034] Furthermore, it also includes a pressing plate 7, one end of which is arranged on the stirring rod 4, and the pressing plate 7 has a pressing surface 701 on the side close to the crushing space 201, and the pressing surface 701 is inclined; after the stirring shaft 3 slides vertically and rotates, it drives several stirring rods 4 to rotate and swing synchronously, so that the pressing surface 701 abuts against the material, squeezing the material between the pressing surface 701 and the crushing space 201 into the crushing space 201.

[0035] In this embodiment, one end of the pressing plate 7 is arranged on the stirring rod 4, and the pressing surface 701 of the pressing plate 7 close to the crushing space 201 is polished to make its surface smooth, so as to reduce the adhesion of materials on the pressing surface 701. The inclination angle of the pressing surface 701 is optimized according to the characteristics of the material and the structure of the crushing chamber 103. For example, for ore materials with high viscosity, a larger inclination angle is adopted to better squeeze the material into the crushing space 201. At the same time, when encountering a relatively regular round material, the material cannot smoothly enter the crushing space 201 and will continuously jump above the crushing space 201. When the inclined pressing surface 701 abuts against the round material, it can limit the vertical jumping of the round material, so that the round material can smoothly enter the crushing space 201.

[0036] The advantage is that the setting of the pressing plate 7 increases the function of forced feeding of materials, which can effectively solve the problem of poor feeding caused by material viscosity or irregular particle shape. Through the swing and extrusion of the pressing plate 7, the material enters the crushing space 201 more smoothly, improving the feeding efficiency and crushing efficiency of the equipment. At the same time, since the material can enter the crushing space 201 more timely and fully, the residence time and accumulation of the material at the feed port 101 are reduced, and the local wear of the moving cone 2 caused by uneven material impact is further reduced, the service life of the moving cone 2 is extended, the overall performance and reliability of the equipment are improved, and the production cost and equipment maintenance cost are reduced.

[0037] Furthermore, one end of the pressing plate 7 is swingably set on the stirring rod 4, and has a contact surface 702 on the side away from the pressing surface 701. The stirring rod 4 has a limiting hole 401, and also includes a torsion spring, which is set at the connection between the pressing plate 7 and the stirring rod 4. The torsion spring is used to provide a force for the other end of the pressing plate 7 to approach the feed port 101. It also includes: an electric telescopic rod 8 is set on the pressing plate 7; a first telescopic member 9 is set on the mounting frame 5; after the first telescopic member 9 is extended, the extended end of the first telescopic member 9 is close to the pressing plate 7, and after the stirring shaft 3 rotates to drive the plurality of stirring rods 4 to rotate, the plurality of contact surfaces 702 sequentially contact with the extended end of the first telescopic member 9, so that the pressing plate 7 rotates, the electric telescopic rod 8 extends, and one end enters the limiting hole 401.

[0038] In this embodiment, the contact surface 702 of the pressing plate 7 away from the pressing surface 701 is a planar structure. A torsion spring is installed at the connection between the pressing plate 7 and the stirring rod 4. The elastic coefficient of the torsion spring is selected according to the swing requirement of the pressing plate 7 to ensure that under normal circumstances, the other end of the stirring rod 4 is close to the feed port 101, so that the pressing plate 7 is in the initial position. The limiting hole 401 on the stirring rod 4 is circular, and its aperture matches the diameter of the telescopic end of the electric telescopic rod 8 to ensure that the electric telescopic rod 8 can be accurately inserted into the limiting hole 401. The electric telescopic rod 8 is fixed on the pressing plate 7, and the first telescopic member 9 adopts a cylinder structure and is installed on the mounting frame 5 through a bracket. During the operation of the equipment, after the first telescopic member 9 is extended, the stirring shaft 3 rotates to drive the stirring rod 4 to rotate, so that the contact surface 702 contacts the extended end of the first telescopic member 9 in turn. Under the action of the contact force, the pressure plate 7 overcomes the elastic force of the torsion spring and rotates. When the pressure plate 7 rotates to a suitable position, the electric telescopic rod 8 extends, and one end accurately enters the limiting hole 401, fixing the pressure plate 7 in the working position so that it can continue to extrude the material.

[0039] Furthermore, the stirring shaft 3 has a cavity 301, the inner wall of the cavity 301 has a key groove 302, and also includes a rotating shaft 10, one end of which is slidably set in the cavity 301; the key block 11 is set on the rotating shaft 10 and slidably set in the key groove 302; the driving device 12 is set on the mounting frame 5, and the output end of the driving device 12 is connected to the other end of the rotating shaft 10. The driving device 12 drives the rotating shaft 10 to rotate, driving the stirring shaft 3 to rotate synchronously.

[0040] In this embodiment, the cavity 301 of the stirring shaft 3 is circular, and the key groove 302 on its inner wall is processed with high precision and low surface roughness to ensure that the key block 11 can slide smoothly in the key groove 302. One end of the rotating shaft 10 is processed into a cylindrical shape matching the cavity 301, and is slidably arranged in the cavity 301 through clearance fit. The key block 11 is welded on the rotating shaft 10, and the key block 11 and the key groove 302 are tightly matched, which can effectively transmit torque. The driving device 12 is composed of a variable frequency motor and a reducer, and is connected to the other end of the rotating shaft 10 through a coupling. During the operation of the equipment, according to the properties of the material and the crushing requirements, the speed and direction of the driving device 12 are adjusted by the frequency converter, and the driving device 12 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the stirring shaft 3 to rotate synchronously through the cooperation of the key block 11 and the key groove 302, thereby achieving the stirring and dispersion of the material.

[0041] Furthermore, the stirring shaft 3 has an annular groove 303, and also includes a sliding ring 13, which is rotatably sleeved in the annular groove 303; a second telescopic member 14, the second telescopic member 14 is arranged on the mounting frame 5, and the protruding end of the second telescopic member 14 is connected to the sliding ring 13. After the second telescopic member 14 is extended, it drives the sliding ring 13 to slide vertically, so that the stirring shaft 3 slides vertically.

[0042] In this embodiment, the annular groove 303 of the stirring shaft 3 is a circular groove, and its surface is polished to reduce the friction when the sliding ring 13 rotates. The sliding ring 13 is made of copper alloy material, has good wear resistance and self-lubricating properties, and is rotatably sleeved in the annular groove 303 through clearance fit. The second telescopic member 14 adopts a hydraulic cylinder structure, which is installed on the mounting frame 5 through an earring connection, and its telescopic end is connected to the sliding ring 13 through a pin shaft. During the operation of the equipment, when it is necessary to adjust the vertical position of the stirring shaft 3, the second telescopic member 14 is started, and the piston rod of the hydraulic cylinder is extended or retracted, driving the sliding ring 13 to slide vertically in the annular groove 303, thereby realizing the vertical sliding of the stirring shaft 3 to meet the crushing requirements of different materials.

[0043] The advantage is that the setting of the sliding ring 13 and the second telescopic member 14 realizes the vertical automatic adjustment function of the stirring shaft 3, and can timely adjust the height of the stirring shaft 3 according to the actual situation of the material, ensuring that the stirring rod 4 is always in the best working position, thereby improving the stirring effect and feeding efficiency of the material. This design improves the automation and adaptability of the equipment, and reduces the workload and time cost of manual adjustment of the equipment due to material changes. At the same time, since the stirring shaft 3 can maintain a good working condition, the risk of local wear of the moving cone 2 is further reduced.

[0044] Furthermore, the stirring rod 4 has a mounting groove 402 at one end close to the inner wall of the crushing chamber 103 , and also includes a cleaning piece 15 , which is slidably arranged in the mounting groove 402 and has the other end abutting against the inner wall of the crushing chamber 103 for cleaning the inner wall of the crushing chamber 103 .

[0045] Furthermore, it also includes an elastic member 16, which is arranged in the installation groove 402, and two ends of the elastic member 16 act on the cleaning member 15 and the stirring rod 4 respectively, so as to provide a force for the cleaning member 15 to approach the inner wall of the crushing chamber 103.

[0046] In this embodiment, the mounting groove 402 at one end of the stirring rod 4 close to the inner wall of the crushing chamber 103 has an internal size that matches the cleaning piece 15. The cleaning piece 15 has a certain elasticity and wear resistance, and one end thereof is processed into a scraper or a brush so as to better fit the inner wall of the crushing chamber 103. The cleaning piece 15 is arranged in the mounting groove 402 as an elastic piece 16 through a compression spring. One end of the elastic piece 16 is connected to the cleaning piece 15, and the other end is connected to the bottom of the mounting groove 402, so as to provide a continuous force for the cleaning piece 15 to approach the inner wall of the crushing chamber 103. During the operation of the equipment, as the stirring rod 4 rotates, the cleaning piece 15 always maintains close contact with the inner wall of the crushing chamber 103 under the action of the elastic piece 16, and the materials adhering to the inner wall of the crushing chamber 103 are cleaned up in time to prevent the accumulation of materials from affecting the crushing effect and the normal operation of the equipment.

[0047] The advantage is that the arrangement of the cleaning member 15 and the elastic member 16 effectively solves the problem of material adhesion and accumulation on the inner wall of the crushing chamber 103, ensures the internal cleanliness of the crushing chamber 103, and improves the crushing efficiency and the stability of product quality. By timely cleaning the inner wall of the crushing chamber 103, the interference of material accumulation on the movement of the moving cone 2 is reduced, and the failure probability and maintenance cost of the equipment are reduced.
