Technical Field
[0001] This utility model relates to the field of crusher technology, specifically a cone crusher with a variable cross-section crushing chamber. Background Technology
[0002] A crusher is a mechanical device used in the crushing industry to break various large materials, such as ores, rocks, and construction waste, into smaller particles through mechanical forces such as compression, impact, and shearing. It is widely used in many industries, including mining, building material production, and resource recycling, and is a key piece of equipment for material processing and efficient resource utilization. However, traditional crushers mostly use a fixed-section crushing chamber. This structure results in a single trajectory for material movement within the chamber, making efficient graded crushing impossible. For example, when processing large materials, material jamming is prone to occur, leading to low crushing efficiency. Furthermore, due to uneven distribution of crushing force, the output particle size is uneven, failing to meet the requirements of modern industry for fine and uniform material particle size. In addition, the vibration damping function of traditional crushers is relatively weak. The strong vibrations generated during operation not only cause loosening and accelerated wear of equipment parts, shortening the equipment's service life, but also generate significant noise, polluting the working environment. Therefore, those skilled in the art have provided a cone crusher with a variable-section crushing chamber to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this invention is to provide a cone crusher with a variable cross-section crushing chamber to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:

A fixing plate is fixedly connected to the bottom of the crushing box, and the top two sides of the fixing plate are fixedly connected to the outer side walls of the crushing box through the shock-absorbing structure.

The damping springs on the side away from the support frame are fixedly connected by the fixing block, and the other side of the fixing block is fixedly connected to the crushing box. The fixing block is movably connected to the connecting groove.
[0008] As a further embodiment of this utility model: the power structure includes a power box, a motor, a round shaft, a driving gear, a driven gear, a protrusion, a rotating shaft, a fixed shaft, and a round plate. The motor is fixedly connected to one side of the power box, and the power output shaft of the motor is fixedly connected to the round shaft. The side of the round shaft away from the motor passes through one side of the power box and is fixedly connected to the driving gear.
[0009] As a further embodiment of this utility model: the round shaft is rotatably connected to the power box, the driven gear is meshed with one side of the driving gear, and a fixed shaft is fixedly connected to the driven gear.
[0010] As a further embodiment of this utility model: the fixed shaft extends through the top of the power box from the side away from the driven gear and is fixedly connected to a circular plate. The fixed shaft is rotatably connected to the power box. A protrusion is fixedly connected to the outer wall of the circular plate. A rotating shaft is fixedly connected to one side of the upper part of the fixed shaft arm.
[0011] As a further embodiment of this utility model: the bottom of the fixed plate is fixedly connected to a discharge port, and the top of the discharge port extends through the top of the fixed plate and is fixedly connected to the crushing box; support plates are fixedly connected to both sides of the bottom of the fixed plate.
[0012] As a further embodiment of this utility model: a movable cone is provided inside the fixed cone, and a fixed frame is movably connected to the top of the movable cone through a ball. The ball is located in the upper part of the movable cone, and a fixed frame is fixedly connected to the ball. Connecting frames are fixedly connected to both sides of the fixed frame. The two sides of the connecting frame are fixedly connected to the inner wall of the feed port. A groove is provided on the inner wall of the movable cone to match the protrusion on the power structure.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. During use, the material is first poured in through the feed port at the top of the crushing box. Then, the motor in the power structure is started. The motor, as the power source, drives the round shaft to start rotating. This process converts electrical energy into mechanical energy, providing power for the subsequent series of operations of the crusher. After the round shaft passes through the power box, it continuously drives the drive gear to rotate synchronously. The drive gear and the driven gear mesh with each other. With the help of gear transmission characteristics, the direction of power transmission is cleverly changed on the one hand, and the speed and torque are reasonably and accurately adjusted to meet the crushing operation requirements on the other hand. Since the driven gear is fixedly connected to the fixed shaft, the fixed shaft will rotate synchronously with the rotation of the driven gear, thereby driving the rotating shaft to rotate, and finally driving the moving cone to start eccentric oscillation, successfully completing the transmission from the motor power to the movement of the moving cone, thus providing the necessary and stable motion conditions for the subsequent material crushing.
[0015] 2. Once the moving cone begins its eccentric oscillation under the power transmission mechanism, the material crushing process commences. The fixed cone inside the crushing chamber has a variable cross-section structure with spiral grooves on its inner side. After the material enters the crushing chamber from the feed inlet, it is guided by the spiral grooves to slide down the fixed cone in a spiral shape, gradually penetrating deeper into the crushing chamber. In the upper section of the crushing chamber, the gap created by the oscillation of the moving cone is relatively large, allowing large pieces of material to easily enter. The moving cone utilizes this gap to perform initial compression and crushing operations on the large pieces of material, causing the material to be initially crushed and continue to slide downwards. As the material slides down to the middle section of the crushing chamber, the cross-section of the fixed cone gradually narrows, and the gap between the moving and fixed cones decreases accordingly. At this point, the moving cone applies a stronger compressive force to the material during its eccentric oscillation. Simultaneously, the spiral grooves cause the material to slide down... The rotational motion greatly enhances the crushing effect, causing the material to be further crushed into smaller particles. When the material reaches the lower section of the crushing chamber, the cross-section of the fixed cone is at its narrowest point. Only fine materials that have been fully crushed and whose particle size meets the preset requirements can be discharged smoothly through the bottom outlet. For materials that do not meet the particle size standard, they will be effectively blocked by the passive cone and return to the middle section under the swinging force of the moving cone to continue the crushing operation until the particle size meets the discharge requirements. The moving cone achieves flexible and stable swinging through the ball-shaped movable connection between the top and the fixed frame. The groove on its inner wall and the protrusion on the circular plate are precisely matched to ensure the stability of the swinging trajectory of the moving cone. During the eccentric swinging process, it works in coordination with the fixed cone to continuously crush the material until the particle size meets the standard and is discharged.
[0016] 3. Throughout the power transmission and material crushing process, the eccentric oscillation of the moving cone will inevitably generate strong periodic vibrations. At this time, the damping structure plays a crucial role. The two sides of the crushing box are reliably connected to the damping structure through fixed blocks. The fixed blocks are embedded in the connecting groove of the support frame and are elastically supported by two damping springs. When the vibration is transmitted to the fixed blocks through the crushing box, the damping springs will compress and deform, efficiently converting the vibration energy into elastic potential energy and absorbing it. The damping springs have a carefully designed elastic coefficient that can effectively attenuate high-frequency vibrations, avoid failures caused by excessive equipment shaking, create a stable operating environment for power transmission and material crushing, reduce equipment wear, significantly extend the service life of the equipment, and effectively ensure that the crusher can continuously and efficiently complete the crushing work.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This embodiment provides a cone crusher with a variable cross-section crushing chamber, including a crushing box 1, a shock-absorbing structure 5, and a power structure 6. A fixing plate 3 is fixedly connected to the bottom of the crushing box 1. The top two sides of the fixing plate 3 are fixedly connected to the outer side walls of the crushing box 1 through the shock-absorbing structure 5. The power structure 6 is fixedly connected to the lower part of one side of the crushing box 1 and the top of the fixing plate 3. A fixed cone 9 is fixedly connected to the upper part of the inside of the crushing box 1. A spiral groove 10 is provided on the inner side wall of the fixed cone 9. A feed inlet 2 is fixedly connected to the top of the crushing box 1. A discharge outlet 7 is fixedly connected to the bottom of the fixing plate 3, and the top of the discharge outlet 7 passes through the top of the fixing plate 3 and is fixedly connected to the crushing box 1. Support plates 4 are fixedly connected to the bottom two sides of the fixing plate 3. The fixed cone 9 contains a movable cone 8. A fixed frame 12 is movably connected to the top of the movable cone 8 via a sphere, which is located in the upper part of the movable cone 8. The fixed frame 12 is fixedly connected to the sphere, and connecting frames 13 are fixedly connected to both sides of the fixed frame 12. The connecting frames 13 are fixedly connected to the inner wall of the feed inlet 2 on both sides. The inner wall of the movable cone 8 has a groove 11 that matches the protrusion 66 on the power structure 6. When the movable cone 8 starts to oscillate eccentrically under the action of the power transmission mechanism, the material crushing operation begins. The fixed cone 9 inside the crushing chamber 1 has a variable cross-section structure, and a spiral groove 10 is provided on its inner side. After the material enters the crushing chamber from the feed inlet 2, it slides down the fixed cone 9 in a spiral shape under the orderly guidance of the spiral groove 10. As the material gradually penetrates deeper into the crushing chamber, the gap created by the oscillation of the moving cone 8 in the upper section is relatively large. This spatial characteristic allows large pieces of material to easily enter. The moving cone 8 utilizes this gap to perform initial compression and crushing operations on the large pieces of material, causing the material to be initially crushed and continue to slide downwards. As the material slides down to the middle section of the crushing chamber, the cross-section of the fixed cone 9 gradually narrows, and the gap between the moving cone 8 and the fixed cone 9 decreases accordingly. At this time, the moving cone 8 applies a stronger compressive force to the material during its eccentric oscillation. Simultaneously, the spiral groove 10 causes the material to rotate during its descent, greatly enhancing the layered crushing effect and promoting further crushing of the material into smaller particles. When the material reaches the lower section of the crushing chamber, the cross-section of the fixed cone 9... When the surface is at its narrowest point, only fine materials that have been fully crushed and whose particle size meets the preset requirements can be smoothly discharged through the bottom outlet 7. Materials that do not meet the particle size standard will be effectively blocked by the passive cone 8 and will return to the middle section under the swing force of the moving cone 8 to continue the crushing operation until the particle size meets the discharge requirements. The moving cone 8 achieves flexible and stable swinging through the ball-shaped movable connection between the top and the fixed frame 12. The groove 11 on its inner side wall and the protrusion 66 on the circular plate 69 are precisely matched to ensure the stability of the swing trajectory of the moving cone 8. During the eccentric swinging process, it works in coordination with the fixed cone 9 to continuously squeeze and crush the material until the particle size meets the standard and is discharged. Example
[0026] Reference Figure 5-6This embodiment is based on the previous embodiment, but differs in that the damping structure 5 includes a support frame 51, a connecting groove 52, damping springs 53, and a fixing block 54. The support frame 51 has a connecting groove 52 on one side, and two damping springs 53 are fixedly connected inside the connecting groove 52. The side of the damping springs 53 away from the support frame 51 is fixedly connected to the fixing block 54, and the other side of the fixing block 54 is fixedly connected to the crushing box 1. The fixing block 54 is movably connected to the connecting groove 52. During the entire process of power transmission and material crushing, the eccentric oscillation of the moving cone 8 will inevitably generate strong periodic vibrations. At this time, the damping structure 5 plays a crucial role. The two sides of the crushing box 1 are reliably connected to the damping structure 5 through the fixing blocks 54, thus fixing... Block 54 is embedded in the connecting groove 52 of the support frame 51 and is elastically supported by two damping springs 53. When vibration is transmitted to the fixed block 54 through the crushing box 1, the damping springs 53 will compress and deform, efficiently converting the vibration energy into elastic potential energy and absorbing it. The damping springs 53 have a carefully designed elastic coefficient, which can effectively attenuate high-frequency vibration, avoid failure caused by excessive shaking of the equipment, create a stable operating environment for power transmission and material crushing process, reduce equipment wear, significantly extend the service life of the equipment, and effectively ensure that the crusher can continuously and efficiently complete the crushing work. The power structure 6 includes a power box 61, a motor 62, a round shaft 63, a drive gear 64, a driven gear 65, a protrusion 66, a rotating shaft 67, and a fixed shaft. 68 and circular plate 69, a motor 62 is fixedly connected to one side of the power box 61, a circular shaft 63 is fixedly connected to the power output shaft of the motor 62, the side of the circular shaft 63 away from the motor 62 passes through one side of the power box 61 and is fixedly connected to a drive gear 64, the circular shaft 63 is rotatably connected to the power box 61, a driven gear 65 is meshed with one side of the drive gear 64, a fixed shaft 68 is fixedly connected to the driven gear 65, the side of the fixed shaft 68 away from the driven gear 65 passes through the top of the power box 61 and is fixedly connected to a circular plate 69, the fixed shaft 68 is rotatably connected to the power box 61, a protrusion 66 is fixedly connected to the outer wall of the circular plate 69, and a rotating shaft 67 is fixedly connected to one side of the upper part of the shaft arm of the fixed shaft 68. When the motor 62 is started, it drives the circular shaft 63 to begin rotating. The rotational motion converts electrical energy into mechanical energy, providing power for the subsequent operation of the crusher. The circular shaft 63 passes through the power box 61 and continuously drives the drive gear 64 to rotate synchronously. The drive gear 64 and the driven gear 65 mesh with each other, and with the help of gear transmission characteristics, they cleverly change the direction of power transmission on the one hand, and make reasonable and precise adjustments to the speed and torque on the other hand to adapt to the crushing operation requirements. Since the driven gear 65 is fixedly connected to the fixed shaft 68, the fixed shaft 68 will rotate synchronously with the rotation of the driven gear 65, thereby driving the rotating shaft 67 to rotate, and finally driving the moving cone 8 to start eccentric oscillation, successfully completing the transmission from motor power to moving cone motion, thus providing the necessary and stable motion conditions for subsequent material crushing.
