Description

Technical Field

[0001] This invention belongs to the field of crushing equipment technology, specifically relating to a cone crusher device and control system for dynamically adjusting crushing force. Background Technology

[0002] With the onset of the Industrial Revolution, people gradually realized that machines replacing manual labor and external forces replacing human labor was an inevitable trend. From manual material crushing to the later use of crushers, people went through a very long process. From having equipment to using it effectively will inevitably be another long process. During this process, people will continuously optimize and seek more convenient and efficient methods to solve current problems faster and better. With the introduction of the concept of intelligent technology, people began to incorporate intelligent devices and sensing systems into equipment, hoping to ensure safe operation and improve the cost-effectiveness of the equipment while completing the crushing task through predictive or mistake-proofing methods.

[0003] Crusher is widely used in the metal mining and metallurgical industry, construction industry, cement industry and sand and gravel aggregate industry. It is suitable for crushing various non-ferrous metal ores, granite, limestone, quartzite, sandstone, etc. However, material crushing is an indispensable process in the industry. According to early statistics, about 12% of the world's electricity is used for material crushing. Of this, about 85% of the electricity is used for material grinding and 15% for material crushing. The grinding efficiency in the process is as low as 1%. Most of the electricity is consumed for its own heat generation, noise generation, metal consumption and the rotation of the cylinder itself.

[0004] In today's call for "energy conservation," to reduce electricity consumption, it is necessary to increase crushing output. The "more crushing, less grinding" approach has emerged, which reduces the grinding process, increases crushing output, and ensures product quality while increasing the crusher's processing capacity and the mill's processing capacity. This aims to reduce electricity and metal consumption, reduce costs, and increase economic benefits.

[0005] In recent years, the wave of intelligentization has swept across the industry. With the continuous upgrading of the crushing sector, crushing equipment must also adapt to this trend. There is a desire for traditional machinery to become more dynamic and efficient, improving accuracy and completion rates through predictive or error-proofing methods. This would reduce personnel involvement, lower labor costs, and improve the traditional image of the crushing industry as dirty, chaotic, and substandard, truly addressing the problem at its root. During equipment use, as working hours increase and the particle size of the materials changes, failure to adjust and maintain the crusher in a timely and effective manner will inevitably damage both the materials and the crusher. If adjustments require large machines and numerous personnel, this will be a significant expense for production enterprises. Therefore, there is a need to find simple, efficient, and effective methods, which will have a significant impact on the crushing industry and even on equipment maintenance. Due to market changes and the increasing demands of customers, both users and manufacturers of crushers in China have begun to show interest in and research various models of crushers. Gradually, different types of crushers have become the focus of the current crushing industry. However, cone crushers still use the compression crushing principle. During the operation of the equipment, the materials are squeezed against each other in the crushing chamber. During the operation of the equipment, the material to be crushed is clamped and held, thereby realizing the process of the material from large size to small size, and finally discharged from the discharge port.

[0006] The cone crusher transmits external power through a horizontal shaft and a small gear to a large gear and a thrust bearing lower plate. The power is then transmitted through a flat key and a thrust bearing upper plate to drive the vibrator assembly to rotate and oscillate. During the rotation and oscillation, the vibrator pushes the moving cone assembly to oscillate, thus completing the crushing action.

[0007] During operation, real-time comparison of output data necessitates dynamic adjustment of the crushing force. Adjusting the crushing force alters the equipment's center of gravity. Excessive changes in force cause internal vibrations that cannot be eliminated, forcing some power to be transmitted externally. Therefore, the equipment and foundation must maintain a dynamic height relative to the main unit's center to minimize vibration without affecting the final product. However, current cone crushers only allow for small adjustments to the discharge port size to alter the final material, lacking dynamic adjustment capabilities. Furthermore, the vibration amplitude depends entirely on the incoming material and lacks automatic liner replacement functions, hindering intelligent production and resulting in poor product gradation and excessively large output sizes. This prevents truly intelligent crushing operations. Summary of the Invention

[0052] A cone crusher control system for dynamically adjusting crushing force, used in the aforementioned cone crusher device for dynamically adjusting crushing force, the system comprising:

[0053] The cone crusher's electrical control unit receives vibration signals and / or finished product detection signals;

[0054] The first drive rack control unit is signal-connected to the electrical control unit of the cone crusher;

[0056] The control panel includes a fixed control panel and a movable control panel, which are connected to the electrical control unit of the cone crusher via signals.

[0057] The display screen is connected to the signal control unit of the cone crusher.

[0058] The material leveling system is connected to the electrical control unit of the cone crusher and is used to accelerate or decelerate the material supply to the crusher.

[0059] Specifically, in one example, the device includes a frame (1), a vibration sensor (2), a damping spring (3), a spring support frame (4), a first drive rack (5), a moving cone assembly (6), a support assembly (7), a vibrator assembly (8), a counterweight (9), a second drive rack (10), a horizontal shaft (11), a pinion (12), a large gear (13), a thrust bearing lower plate (14), a flat key (15), and a thrust bearing upper plate (16). The damping spring (3) is bolted to the spring support frame (4). The spring support frame (4) is equipped with a first drive rack (5) which can move up and down on the outer ring of the frame (1). The moving cone (6-2) on the moving cone assembly (1) is fixedly mounted on the support (7) assembly. The bottom of the main shaft (6-1) on the moving cone assembly (6) is inserted into the inner hole of the vibrator assembly (8) and is clearance-fitted with it. The counterweight (9) is equipped with a second drive rack (10) which can move up and down on the outer ring of the vibrator assembly (8). The ring moves up and down. The horizontal shaft (11) is mounted on the frame (1). One end is equipped with a small gear (12), and the other end is connected to an external power source. The small gear (12) and the large gear (13) are meshed together. A thrust bearing lower plate (14) is mounted on the upper part of the large gear (13). A flat key (15) is installed inside the thrust bearing lower plate (14). A thrust bearing upper plate (16) is mounted on the upper part of the flat key (15). The thrust bearing upper plate (16) is fixedly mounted together with the vibrator assembly (8). The position of the counterweight (9) is changed by the second drive rack (10), thereby changing the center of gravity of the vibrator assembly (8) and adjusting the crushing force. While changing the crushing force, the position of the foundation relative to the frame is changed by the first drive rack (5), thereby adjusting the magnitude of the external force, improving the vibration of the equipment to the outside, reducing the impact on the installation foundation, adjusting the crushing force, and improving the particle size composition of the final product.

[0060] Among them, the outer ring of the frame (1) is machined with multiple vertical upward threads, the thread profile is the same as that of the first drive rack (5), and its strength is sufficient to support the equipment and foreign materials.

[0061] Among them, a vibration sensor (2) is installed on the frame (1) to monitor the amplitude and vibration frequency of the equipment in real time and transmit signals in a timely manner to drive the first drive rack (5) on the upper part of the spring support frame (4) to work.

[0062] Among them, the first drive rack (5) is equipped with a drive motor. In manual mode, the motor is controlled by observation, while in automatic mode, it is controlled and adjusted by receiving signals from the vibration sensor (2).

[0063] Among them, the outer ring of the vibrator assembly (8) is machined with multiple vertical upward threads, the thread profile of which is the same as that of the second drive rack (10), and its strength is sufficient to support the counterweight.

[0064] The second drive rack (10) is mounted on the counterweight (9) and engages with the thread on the vibrator assembly (8), which can drive the counterweight (9) to move up and down.

[0065] The second drive rack (10) is equipped with a drive motor, and the position of the counterweight (9) can be manually operated in manual mode and dynamically adjusted according to the automatic screening result of the material output in automatic mode.

[0066] As the wear of the crusher's wear parts causes the final product particle size to change, the position of the counterweight (9) is adjusted to change the center of gravity and improve the crushing force. When the configuration position reaches the limit position, a signal to replace the wear parts is issued to prompt the replacement of the wear parts.

[0067] Reference Figure 3 The cone crusher is equipped with a cone crusher electrical control unit, which can be operated independently in working mode, debugging mode, and clearing mode. It is also equipped with a fixed control panel and a mobile operation panel, which can be controlled independently according to actual needs. All technical parameters can be projected onto the display screen for display.

[0068] Among them, the cone crusher electrical control unit can be controlled independently, the receiving material level system, the first drive rack (5) control system, and the second drive rack (10) control system can also be combined and controlled simultaneously.

[0069] The cone crusher is equipped with a cone crusher electrical control unit, which can be operated independently in working mode, debugging mode, and clearing mode. It is also equipped with a fixed control panel and a mobile operation panel, which can be controlled independently according to actual needs. All technical parameters can be projected onto the display screen for display.

[0070] When the cone crusher control unit receives a vibration signal, it will trigger the first drive rack (5) to move. The first drive rack (5) will move up and down through the equipped motor, thereby controlling the specific position of the crusher damping spring. When the first drive rack (5) moves beyond its travel, it will send a signal back to the cone crusher control unit, thereby controlling the material level system to accelerate or decelerate the material supply to the crusher. When the material level system has been triggered and the vibration signal continues to transmit, the cone crusher control unit will combine the finished product detection signal to control the second drive rack (10) to move. When the second drive rack (10) cannot receive the signal and moves, it will send a signal back to the cone crusher control unit to notify it to stop and issue a stop alarm.

[0071] When the cone crusher control unit receives the finished product detection signal, it triggers the second drive rack (10) control system to adjust the operation according to the judgment result to meet the final required finished product. When the finished product detection signal is continuously output, the second drive rack (10) control system is triggered. When its detection position is out of tolerance and cannot match the finished product detection signal, it indicates that the size of the crusher discharge port needs to be adjusted or the cost needs to be replaced. The feedback is centrally sent to the cone crusher control system to notify it to stop and issue a shutdown alarm.

[0072] This invention provides a cone crusher structure and control method. The main equipment control system is driven by vibration sensor signal. The first drive rack (5) is adjusted to automatically fit the center of gravity position, reduce the equipment amplitude, improve the requirements of the external transmission position on the main equipment, and ensure that the equipment operates under safe conditions. It has a certain adjustment feedback effect on the crushing force. The finished product detection signal triggers the second drive rack (10) to work. The position of the counterweight is changed by the second drive rack (10), thereby changing the center of gravity position of the vibrator assembly (8), thereby adjusting the crushing force and improving the crushing force. After overshoot, it can automatically feed back and retrieve the reason for shutdown (such as replacing the liner, adjusting the discharge port size, etc.). At the same time, the main equipment is monitored for safety and intelligence, further improving the intelligence level of the equipment. While changing the crushing force, the position of the foundation relative to the frame (1) is changed by the first drive rack (5), thereby adjusting the magnitude of the external force, improving the vibration magnitude of the equipment to the outside, and improving the impact on the installation foundation.
