Description

Technical Field

[0001] The invention belongs to the technical field of crushing equipment, and in particular relates to a cone crusher device and a control system for dynamically adjusting crushing force. Background Art

[0002] With the beginning of the Industrial Revolution, people gradually began to realize that it is an inevitable trend for machines to replace manual work and external forces to replace human labor. From manual crushing of materials to the later use of crushers to crush materials, people have gone through a very long process. From having equipment to being able to use the equipment well will inevitably go through a long process. In this process, people will continue to optimize and find more convenient and quick ways and methods to solve today's problems faster and better. With the introduction of the concept of intelligence, people began to introduce smart devices and sensor systems into the equipment, hoping to ensure the safety of equipment use and improve the cost-effectiveness of the equipment by predicting or preventing mistakes while completing the crushing task.

[0003] Crusher is widely used in metal mining, metallurgy, construction, cement and sand and gravel aggregate industries. 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 which about 85% is used for material grinding and 15% is used for material crushing. The grinding efficiency in the process is as low as 1%, and most of the electricity is consumed for its own heating, sound generation, metal consumption and the rotation of the cylinder itself.

[0004] Nowadays, under the call of "energy saving", in order to reduce electricity, it is necessary to increase the crushing output. Therefore, "more crushing and less grinding" came into being. It reduces the grinding process, increases the crushing output, and ensures product quality. Under the premise, it increases the crusher's processing capacity and improves the grinding machine's processing capacity, so as to reduce electricity consumption and metal consumption, reduce costs and increase economic benefits.

[0005] In recent years, the wave of intelligence has come. With the continuous upgrading of the crushing field, crushing equipment must also follow the trend. It is hoped that traditional mechanical equipment can have more vitality and breath, and can improve the accuracy and completion rate of equipment through pre-judgment or fool-proof methods, avoid excessive personnel participation, reduce personnel costs and other issues, and improve the impression of dirty, messy and poor in the traditional crushing field, and truly start from the actual situation and solve the problem to a fundamental extent. During the use of equipment, with the increase of working time and the different particle sizes of working materials, if the crusher cannot be adjusted and maintained in time and effectively, it will inevitably cause damage to the material and crusher. If a large machine and multiple personnel are required to assist in the adjustment process, it will inevitably be a large expense for the production enterprise. Therefore, it is necessary to find a method with simple methods, light tasks and good effects, which will have a good effect on the crusher field and even the repair and maintenance of equipment. Due to changes in market conditions and the continuous needs of customers and owners, both domestic users of crushers and equipment manufacturers have begun to be interested in and study various types of crushers. Gradually, different types of crushers have also begun to become equipment models that the current crusher industry has begun to pay attention to. However, the cone crusher still uses the extrusion 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 materials to be crushed are clamped, thereby realizing a process from large size to small size, and finally discharged from the discharge port.

[0006] The cone crusher transmits the external motive force to the large gear and the lower plate of the thrust bearing through the horizontal shaft and the small gear, and drives the exciter assembly to rotate and swing through the flat key and the upper plate of the thrust bearing. The exciter pushes the moving cone assembly to swing during the rotation and swing process to complete the crushing action.

[0007] During the working process, the real-time comparison of the discharge result data requires the dynamic adjustment of the crushing force. Once the crushing force is adjusted, the center of gravity of the equipment will change. When the change is too large, the vibration generated inside the machine cannot be eliminated by itself, and part of the power is forced to be transmitted to the outside of the equipment and expressed. This requires that the installation position of the equipment and the foundation always maintain a certain dynamic height with the center position of the host, so as to reduce the amplitude of the equipment without affecting the final product. However, the cone crushers currently on the market can only adjust the size of the discharge port in a very small direction to change the final material product, and do not have a dynamic adjustment function. At the same time, the amplitude of the equipment can only be completely dependent on the incoming material situation, and cannot automatically detect the replacement of liner and other functions, and cannot achieve smart production. The degree of intelligence is not high, and it is easy to have unreasonable grading of finished materials and serious over-diameter of material output, and it is impossible to achieve intelligent crushing. Summary of the invention

[0057] A display screen connected to the electric control unit signal of the cone crusher;

[0058] The material level system is connected to the cone crusher electronic control unit signal and is used to accelerate or decelerate the front-end material to feed the crusher.

[0059] Specifically, in one example, the device includes a frame (1), a vibration sensor (2), a shock-absorbing spring (3), a spring support frame (4), a first drive rack (5), a moving cone assembly (6), a support assembly (7), an exciter assembly (8), a counterweight (9), a second drive rack (10), a horizontal shaft (11), a small gear (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 mounted on the spring support frame (4) by bolts. The spring support frame (4) is equipped with a first driving 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 exciter assembly (8) and is matched with the clearance therebetween. The counterweight (9) is equipped with a second driving rack (10) which can be moved on the outer ring of the exciter assembly (8). The circle moves up and down, the horizontal shaft (11) is installed on the frame (1), one end of which is installed with a small gear (12), and the other end is connected to the external power. The small gear (12) and the large gear (13) are installed together by meshing, and the upper part of the large gear (13) is installed with a thrust bearing lower plate (14), and a flat key (15) is installed in the thrust bearing lower plate (14). The upper part of the flat key (15) is installed with a thrust bearing upper plate (16), and the thrust bearing upper plate (16) is fixedly installed with the exciter assembly (8). The position of the counterweight (9) is changed by the second drive rack (10), thereby changing the center of gravity of the exciter assembly (8), thereby adjusting the size of the crushing force, and changing the crushing force while changing the position of the base relative to the frame through the first drive rack (5), thereby adjusting the size of the external force, improving the external vibration size of the equipment, improving the impact on the installation base, adjusting the size of the crushing force, and improving the particle size composition of the final product.

[0060] The outer ring of the frame (1) is processed with a plurality of vertical upward threads, the thread profile of which is the same as the thread profile of the first drive rack (5), and the strength thereof is sufficient to support the equipment and foreign materials.

[0061] A vibration sensor (2) is installed on the frame (1) to monitor the amplitude and vibration frequency of the equipment in real time and promptly transmit a signal to drive the first driving rack (5) on the upper part of the spring support frame (4) to work.

[0062] A driving motor is installed on the upper part of the first driving rack (5). The motor is controlled simply by observation in manual mode and receives the signal of the vibration sensor (2) for control and adjustment in automatic mode.

[0063] The outer ring of the vibrator assembly (8) is processed with a plurality of vertical upward threads, the thread profile of which is consistent with the thread profile of the second drive rack (10), and the strength thereof is sufficient to support the counterweight.

[0064] The second driving rack (10) is installed on the counterweight (9) and cooperates with the thread on the exciter assembly (8) to drive the counterweight (9) to move up and down.

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

[0066] As the wear of the wear-resistant parts of the crusher causes the particle size of the final product 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 for replacing the wear-resistant parts is issued to prompt the wear-resistant parts to be replaced.

[0067] Reference Figure 3 The cone crusher is equipped with a cone crusher electronic control unit, which can be operated independently in working mode, debugging mode and cavity 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] The cone crusher electric control unit can be independently controlled, and the receiving material level system, the first drive rack (5) control system, and the second drive rack (10) control system can also be simultaneously and jointly controlled for fitting.

[0069] Among them, the cone crusher is equipped with a cone crusher electronic control unit, which can be operated independently in working mode, debugging mode and cavity 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 electronic control unit receives the vibration signal, it triggers the first drive rack (5) to move. The first drive rack (5) is adjusted up and down by the equipped motor to drive the main device to move up and down, thereby controlling the specific position of the crusher shock-absorbing spring installation. When the movement position of the first drive rack (5) exceeds the travel, the signal is fed back to the cone crusher electronic control unit, thereby controlling the material level system and accelerating or decelerating the front-end material to supply the crusher. When the material level system has been triggered and the vibration signal is still continuously transmitted, the cone crusher electronic 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 move, it will be fed back to the cone crusher electronic control unit to notify it to stop and issue a stop alarm.

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

[0072] The embodiment of the present invention provides a cone crusher structure and control method, which drives the host equipment control system through the vibration sensor signal, and automatically fits the center of gravity position through the first drive rack (5), reduces the equipment amplitude, improves the requirements of the external transmission position on the host equipment, and ensures that the equipment is operated under safe conditions, and has a certain adjustment feedback effect on the adjustment of the crushing force; the finished product detection signal triggers the second drive rack (10) to work, and the position of the counterweight is changed through the second drive rack (10), thereby changing the center of gravity position of the exciter assembly (8), thereby adjusting the size of the crushing force, adjusting and improving the crushing force, and automatically feedback and retrieve the reason for the shutdown (such as replacing the liner, adjusting the size of the discharge port, etc.) after the overrun, and at the same time, the host is safely and intelligently monitored, further improving the intelligence of the equipment, and changing the crushing force while changing the position of the foundation relative to the frame (1) through the first drive rack (5), thereby adjusting the size of the external force, improving the external vibration of the equipment, and improving the impact on the installation foundation.
