Abstract
Description
Technical Field
[0001] This invention relates to a monitoring and adjustment system and method for the discharge port of a cone crusher, as well as a hydraulic cone crusher, belonging to the technical field of cone crushers. Background Technology
[0002] Hydraulic cone crushers are key equipment in the processing of incoming materials in large and medium-sized mines and the recycling of construction waste generated during engineering construction. They feature high production capacity, small product particle size, stable operation, and reliable performance, and are widely used in fine crushing operations. During operation, the small gear assembly drives the eccentric assembly to rotate via large and small gears, which in turn drives the main shaft assembly in a cone-shaped oscillating motion. When the main shaft oscillates, the main shaft assembly rotates periodically relative to the upper frame assembly. When the main shaft assembly (moving cone liner) approaches the upper frame assembly (fixed cone liner), the material between them is crushed by compression. When the main shaft assembly moves away from the upper frame assembly, the crushed material is discharged downwards through the discharge port by its own weight. By pumping hydraulic oil into the hydraulic cylinder assembly and adjusting the piston position, the main shaft assembly is raised or lowered to achieve a suitable discharge port, ultimately controlling the product particle size.
[0003] During operation, existing cone crushers may experience changes in the discharge port due to wear or other reasons. If these changes are not addressed in a timely manner, they may affect the equipment's operating power or alter the particle shape distribution of the discharged material. Summary of the Invention
[0004] To address the problems existing in the prior art, the present invention provides a cone crusher discharge port monitoring and adjustment system, method, and hydraulic cone crusher, enabling the cone crusher to adapt to most working conditions and allowing the equipment to work stably in the initial set state, thereby improving the equipment's working efficiency.
[0005] To achieve the above objectives, the present invention employs a cone motor discharge port monitoring and adjustment system, comprising:
[0006] Main controller;
[0007] A hydraulic system is connected to the main controller. The hydraulic system is equipped with a spindle cylinder pressure detection unit and a spindle position detection unit. The spindle cylinder pressure detection unit is used to detect the pressure information of the spindle cylinder, and the spindle position detection unit is used to detect the position information of the spindle. Each detection unit transmits the pressure and position information to the main controller.
[0008] A feeding system, which is connected to the main controller, is controlled by the main controller to feed material into the cone motor.
[0009] An instrument, which is connected to the main controller, is used to select the required control mode and send input commands to the main controller;
[0010] The main motor is connected to the main controller and is used to drive the conical main unit to work. The main motor is equipped with a main power detection unit for detecting the main power information and transmitting it to the main controller.
[0011] The main controller adjusts the discharge port of the cone motor based on the received spindle cylinder pressure information, spindle position information, main motor power information, and instrument input information.
[0012] In some embodiments, the control modes on the instrument include a host real-time power fuzzy control mode based on maintaining power, a fuzzy control mode based on setting a single discharge port, and a control mode based on setting multiple discharge ports.
[0013] In some embodiments, the host real-time power fuzzy control mode based on maintenance power specifically includes:
[0014] The system completes the acquisition of the sustaining power, and the desired control mode is selected in the instrument;
[0015] If the average power of the host is detected to be greater than the maintenance power for one minute, or the average power of the host is greater than the maintenance power * 140% more than 10 times within one minute, it is determined that the discharge port is reduced. By controlling the main shaft hydraulic motor to reverse, the hydraulic pump is driven to reverse, so that the main shaft cylinder drops by 1mm or the dropping action lasts for 1 second, and the motor rotation is stopped.
[0016] If the average power of the host machine is detected to be less than the maintenance power for five consecutive minutes, it is determined that the discharge port has increased. By controlling the main shaft hydraulic motor to rotate forward, the hydraulic pump is driven to rotate forward, causing the main shaft cylinder to rise by 1mm or the rising action to last for 1 second, and then the motor rotation is stopped.
[0017] In some embodiments, the fuzzy control mode based on a single discharge port includes the following steps:
[0018] The first step is for the system to complete the calculation of discharge port adjustment and pressure maintenance, and select the single discharge port control mode in the instrument.
[0019] The second step is to detect that the average pressure of the main shaft is greater than the holding pressure within two minutes, or the average pressure of the main shaft is greater than the holding pressure * 150% more than 10 times within five minutes. Then, it is determined that the discharge port is reduced. By controlling the main shaft hydraulic motor to reverse, the hydraulic pump is driven to reverse, so that the main shaft cylinder drops by 1mm or the dropping action lasts for 1 second, and the motor rotation is stopped.
[0020] The third step is to determine that the average pressure of the main shaft is less than the maintenance pressure within five minutes. Then, the discharge port is increased. By controlling the main shaft hydraulic motor to rotate forward, the hydraulic pump is driven to rotate forward, so that the main shaft cylinder rises by 1mm or the rising action lasts for 1 second, and the motor rotation is stopped.
[0021] In some embodiments, the control mode based on setting multiple discharge ports includes the following steps:
[0022] Step 1: Select the multi-outlet control mode in the instrument and set the size of each multi-outlet as SET 1, SET 2, and SET 3, with time intervals of TIME 1, TIME 2, and TIME 3, respectively. Adjust the outlet to the SET 1 position.
[0023] The second step is to start the working time. When the equipment has been working at the current discharge port for TIME 1, start the main shaft hydraulic motor, drive the hydraulic pump, and drive the main shaft to move through the oil cylinder. Combined with the oil cylinder position sensor, adjust the discharge port to the SET2 set position.
[0024] The third step is to start the working time. When the equipment has been working at the current discharge port for TIME 2, start the main shaft hydraulic motor, drive the hydraulic pump, and drive the main shaft to move through the oil cylinder. Combined with the oil cylinder position sensor, adjust the discharge port to the SET3 set position.
[0025] Step 4: Start working timer. When the equipment has been working at the current discharge port for TIME 3, start the main shaft hydraulic motor, drive the hydraulic pump, and drive the main shaft to move through the oil cylinder. Combined with the oil cylinder position sensor, adjust the discharge port to the SET1 set position.
[0026] In some embodiments, the hydraulic system includes a hydraulic tank, a power assembly, a control valve assembly, and a hydraulic cylinder;
[0027] The hydraulic oil tank is connected to the power assembly via pipelines, the power assembly is connected to the control valve group via pipelines, the control valve group is connected to the hydraulic cylinder via pipelines, a cylinder position sensor is installed on the hydraulic cylinder, a pressure sensor is installed on the pipeline between the control valve group and the hydraulic cylinder, the hydraulic oil tank is connected to the pipeline between the control valve group and the hydraulic cylinder via an overflow valve, and a filter is installed on the pipeline between the control valve group and the hydraulic oil tank.
[0028] In some embodiments, the power assembly includes a motor and a hydraulic pump, and the control valve group includes a cylinder downward pressure regulating valve, a cylinder upward pressure regulating valve, and a cylinder downward manual valve.
[0029] A second aspect of the present invention provides a method for monitoring and adjusting the discharge port of a conical motor, employing the aforementioned monitoring and adjusting system for the discharge port of a conical motor, comprising the following steps:
[0030] (1) Monitoring phase
[0031] S1. Start the feeder and cone motor. The feeder continuously feeds material to make the cone motor work at full capacity. The average pressure of the cone motor in the first five minutes before it starts working at full capacity is used as the maintenance pressure at the outlet. The average power of the cone motor in the first five minutes before it starts working at full capacity is used as the maintenance power.
[0032] S2. Select the host real-time power fuzzy control mode based on the maintenance power, the fuzzy control mode based on the setting of a single discharge port, or the control mode based on the setting of multiple discharge ports through the control mode on the instrument.
[0033] S3. When in the real-time power fuzzy control mode of the host, if the host average power is detected to be greater than the maintenance power for one minute for a continuous period of one minute, or if the host average power is greater than the maintenance power * 140% more than 10 times within one minute, it is determined that the discharge port is reduced; if the host average power is detected to be less than the maintenance power for five consecutive minutes, it is determined that the discharge port is increased.
[0034] When in fuzzy control mode based on a single discharge port, if the average spindle pressure is greater than the holding pressure for two consecutive minutes, or the average spindle pressure is greater than 150% of the holding pressure for five consecutive minutes more than 10 times, the discharge port is determined to decrease; if the average spindle pressure is less than the holding pressure for five consecutive minutes, the discharge port is determined to increase.
[0035] When in the control mode based on multiple discharge ports, the discharge ports are adjusted according to the working time.
[0036] (2) Adjustment phase
[0037] When the discharge port is determined to decrease, the control cylinder lowers; when the discharge port is determined to increase, the control cylinder rises.
[0038] In some embodiments, when it is determined that the discharge port is reduced, the main shaft hydraulic motor is reversed, which drives the hydraulic pump to reverse, so that the main shaft cylinder drops by 1mm or the dropping action lasts for 1 second, and the motor rotation is stopped.
[0039] When the discharge port is determined to be enlarged, the hydraulic motor of the main shaft is controlled to rotate forward, which drives the hydraulic pump to rotate forward, causing the main shaft cylinder to rise by 1mm or the rising action to last for 1 second, and then the motor rotation is stopped.
[0040] A third aspect of the present invention provides a hydraulic cone crusher, wherein the hydraulic cone crusher is equipped with the aforementioned cone crusher main discharge port monitoring and adjustment system.
[0041] Compared with existing technologies, the cone motor discharge port monitoring and adjustment system of this invention allows for the selection of three control modes via an instrument: a real-time power fuzzy control mode based on maintaining power, a fuzzy control mode based on setting a single discharge port, and a control mode based on setting multiple discharge ports. In the power fuzzy control mode, the power during equipment production is kept relatively stable. In the single discharge port control mode, the discharge port is kept relatively stable. In the multi-discharge port control mode, the discharge port can be flexibly adjusted according to process requirements. This invention reduces the impact of foreign objects on the equipment and minimizes equipment damage by rapidly increasing the discharge port size. This invention allows for flexible switching between the power fuzzy control mode, single discharge port mode, and multi-discharge port mode based on actual production conditions, enabling the equipment to adapt to various incoming materials, operating conditions, and production process requirements.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.
[0051] Example 1
[0052] like Figure 1 As shown, a monitoring and adjustment system for the discharge port of a conical motor includes a main controller, a hydraulic system, a feeding system, instruments, and a main motor. The hydraulic system is connected to the main controller. The hydraulic system is equipped with a spindle cylinder pressure detection unit and a spindle position detection unit. The spindle cylinder pressure detection unit is used to detect the pressure information of the spindle cylinder, and the spindle position detection unit is used to detect the position information of the spindle. Each detection unit transmits the pressure and position information to the main controller.
[0053] The feeding system is connected to the main controller, and the main controller controls the feeding system to feed material into the cone motor.
[0054] The instrument is connected to the main controller and is used to select the required control mode and send input commands to the main controller.
[0055] The main motor is connected to the main controller and is used to drive the conical main unit to work. The main motor is equipped with a main power detection unit, which is used to detect the main power information and transmit it to the main controller.
[0056] The main controller adjusts the discharge port of the cone motor based on the received spindle cylinder pressure information, spindle position information, main motor power information, and instrument input information.
[0057] In some embodiments, the control modes on the instrument include a host real-time power fuzzy control mode based on maintaining power, a fuzzy control mode based on setting a single discharge port, and a control mode based on setting multiple discharge ports.
[0058] In some embodiments, such as Figure 4 As shown, the host real-time power fuzzy control mode based on maintenance power has the following steps:
[0059] First step: Before implementing this control mode, the system has completed the acquisition of sustaining power. Select the power mode in the instrument.
[0060] The second step is to detect that the average power of the host machine is greater than the maintenance power for one minute, or the average power of the host machine is greater than the maintenance power * 140% more than 10 times in one minute. It is determined that the discharge port is reduced. At this time, the operating power of the equipment should be reduced. By controlling the main shaft hydraulic motor to reverse, the hydraulic pump is driven to reverse, so that the main shaft cylinder drops by 1mm or the dropping action lasts for 1 second, and the motor rotation is stopped.
[0061] Step 3: If the average power of the host machine is detected to be less than the maintenance power for five consecutive minutes, it is determined that the discharge port has increased. At this time, the operating power of the equipment should be increased. By controlling the main shaft hydraulic motor to rotate forward, the hydraulic pump will be driven to rotate forward, so that the main shaft cylinder rises by 1mm or the rising action lasts for 1 second, and then the motor rotation is stopped.
[0062] In some embodiments, such as Figure 5 As shown, the fuzzy control mode based on a single discharge port includes the following steps:
[0063] First step: Before implementing this control mode, the system has completed the precise adjustment of the discharge port and the calculation of the maintaining pressure. In addition, select the single discharge port mode in the instrument.
[0064] The second step is to detect that the average spindle pressure is greater than the maintenance pressure for two consecutive minutes, or that the average spindle pressure is greater than the maintenance pressure * 150% for five consecutive minutes more than 10 times. In this case, the discharge port is reduced. The discharge port is increased by controlling the spindle hydraulic motor to reverse, which drives the hydraulic pump to reverse, so that the spindle cylinder drops by 1mm or the dropping action lasts for 1 second, and then the motor stops rotating.
[0065] Third step: If the average pressure of the spindle is detected to be less than the maintenance pressure for five minutes, it is determined that the discharge port has increased. At this time, the discharge port should be reduced. By controlling the spindle hydraulic motor to rotate forward, the hydraulic pump is driven to rotate forward, so that the spindle cylinder rises by 1mm or the rising action lasts for 1 second, and then the motor rotation is stopped.
[0066] In some embodiments, such as Figure 6 As shown, the control mode based on setting multiple discharge ports involves the following steps:
[0067] Step 1: Select the multi-outlet control mode in the instrument and set the size of each multi-outlet as SET 1, SET 2, and SET 3, with time intervals of TIME 1, TIME 2, and TIME 3, respectively. Adjust the outlet to the SET 1 position.
[0068] The second step is to start the working time. When the equipment has been working at the current discharge port for TIME 1, start the main shaft hydraulic motor, drive the hydraulic pump, and drive the main shaft to move through the oil cylinder. Combined with the oil cylinder position sensor, adjust the discharge port to the SET2 set position.
[0069] The third step is to start the working time. When the equipment has been working at the current discharge port for TIME 2, start the main shaft hydraulic motor, drive the hydraulic pump, and drive the main shaft to move through the oil cylinder. Combined with the oil cylinder position sensor, adjust the discharge port to the SET3 set position.
[0070] Step 4: Start working timer. When the equipment has been working at the current discharge port for TIME 3, start the main shaft hydraulic motor, drive the hydraulic pump, and drive the main shaft to move through the oil cylinder. Combined with the oil cylinder position sensor, adjust the discharge port to the SET1 set position.
[0071] In some embodiments, such as Figure 2 As shown, the hydraulic system includes a hydraulic oil tank 1, a power assembly 2, a control valve group, and a hydraulic cylinder 3;
[0072] The hydraulic oil tank 1 is connected to the power assembly 2 via a pipeline. The power assembly 2 is connected to the control valve group via a pipeline. The control valve group is connected to the hydraulic cylinder 3 via a pipeline. A cylinder position sensor 6 is installed on the hydraulic cylinder 3. A pressure sensor 5 is installed on the pipeline between the control valve group and the hydraulic cylinder 3. The hydraulic oil tank 1 is connected to the pipeline between the control valve group and the hydraulic cylinder 3 via an overflow valve 4. A filter 10 is installed on the pipeline between the control valve group and the hydraulic oil tank 1.
[0073] In some embodiments, such as Figure 2 As shown, the power assembly 2 includes a motor and a hydraulic pump, and the control valve group includes a cylinder downward pressure regulating valve 7, a cylinder upward pressure regulating valve 8, and a cylinder downward manual valve 9 for driving the cylinder to move up and down.
[0074] During specific adjustment and control, moving upward: the power assembly 2 is started in the forward direction, the hydraulic oil goes from port T through the check valve to port A, the power assembly 2 draws oil and pumps the oil to port B; the oil at port B goes through the hydraulic control check valve to port P, the oil flows to the hydraulic cylinder 3, the hydraulic cylinder 3 rises, and the discharge port decreases.
[0075] Downward movement: Reverse start power assembly 2, hydraulic oil flows from port T through the check valve to port B, power assembly 2 draws oil and pumps it to port A; oil at port A opens the hydraulic control check valve, power assembly 2 stops drawing oil from port T and draws oil from port P, pumps it to port A, passes through the check valve, passes through the cylinder downward pressure regulating valve 7 and filter 10 and flows back to hydraulic oil tank 1, hydraulic cylinder 3 descends, and the discharge port increases.
[0076] Overload pressure relief: When a hard foreign object enters the cone-shaped main unit, the cylinder pressure will rise sharply, the overflow valve 4 will open, and the oil will return to the hydraulic oil tank 1.
[0077] In a second aspect, the present invention provides a hydraulic cone crusher, wherein the hydraulic cone crusher is equipped with the aforementioned cone crusher main discharge port monitoring and adjustment system.
[0078] Example 2
[0079] like Figures 1-6 As shown, a method for monitoring and adjusting the discharge port of a cone milling machine includes the following steps:
[0080] S1. Start the feeder and cone motor. Before the feeder feeds the cone motor, put lead blocks into the cone cavity. After being squeezed, the lead blocks are discharged through the outlet. The size of the current outlet is obtained by measuring the size of the lead blocks. The size of the outlet is compared with the size of the outlet set by the instrument. If there is a deviation, start the main shaft hydraulic motor and adjust the movement of the main shaft cylinder. Combined with the cylinder position sensor 6, the actual size of the outlet is made to match the setting.
[0081] Then control the feeder to continuously feed so that the cone motor works at full capacity; use the average pressure of the cone motor in the first five minutes before it starts working at full capacity as the maintaining pressure of the outlet, and use the average power of the main motor in the first five minutes before it starts working at full capacity as the maintaining power.
[0082] S2. Select the host real-time power fuzzy control mode based on the maintenance power, the fuzzy control mode based on the setting of a single discharge port, or the control mode based on the setting of multiple discharge ports through the control mode on the instrument.
[0083] S3. When in the real-time power fuzzy control mode of the host machine, if the host machine's average power is detected to be greater than the maintenance power for one minute, or if the host machine's average power is greater than the maintenance power * 140% more than 10 times within one minute, it is determined that the discharge port is decreasing. By controlling the main spindle hydraulic motor to reverse, the hydraulic pump is driven to reverse, causing the main spindle cylinder to descend by 1mm or the descent action to last for 1 second, and then the motor rotation is stopped. If the host machine's average power is detected to be less than the maintenance power for five minutes, it is determined that the discharge port is increasing. By controlling the main spindle hydraulic motor to rotate forward, the hydraulic pump is driven to rotate forward, causing the main spindle cylinder to rise by 1mm or the rise action to last for 1 second, and then the motor rotation is stopped.
[0084] When in fuzzy control mode based on a single discharge port, if the average spindle pressure is detected to be greater than the holding pressure for two consecutive minutes, or if the average spindle pressure is detected to be greater than the holding pressure * 150% more than 10 times for five consecutive minutes, the discharge port is determined to be reduced. The spindle hydraulic motor is controlled to reverse, which drives the hydraulic pump to reverse, causing the spindle cylinder to descend by 1mm or the descent action to last for 1 second, and then the motor rotation is stopped. If the average spindle pressure is detected to be less than the holding pressure for five consecutive minutes, the discharge port is determined to be increased. The spindle hydraulic motor is controlled to rotate forward, which drives the hydraulic pump to rotate forward, causing the spindle cylinder to rise by 1mm or the rise action to last for 1 second, and then the motor rotation is stopped.
[0085] When in control mode based on multiple discharge ports, the sizes of the multiple discharge ports are set as SET1, SET2, and SET3, with time intervals of TIME1, TIME2, and TIME3, respectively. The discharge port is adjusted to the SET1 position. When the equipment has been working at the current discharge port for TIME1, the main spindle hydraulic motor is started, driving the hydraulic pump, which in turn moves the main spindle via the cylinder. Combined with the cylinder position sensor, the discharge port is adjusted to the SET2 position. When the equipment has been working at the current discharge port for TIME2, the main spindle hydraulic motor is started, driving the hydraulic pump, which in turn moves the main spindle via the cylinder. Combined with the cylinder position sensor, the discharge port is adjusted to the SET3 position. When the equipment has been working at the current discharge port for TIME3, the main spindle hydraulic motor is started, driving the hydraulic pump, which in turn moves the main spindle via the cylinder. Combined with the cylinder position sensor, the discharge port is adjusted to the SET1 position.
[0086] To prevent overload impact from metal or other large hard objects during operation of the cone mill, this invention incorporates two layers of protection. One is software-based: when the spindle pressure exceeds 7.5 Mbar for 1 second, the spindle hydraulic motor reverses, causing the hydraulic pump to reverse as well, moving the spindle downwards to the lowest permissible position. The other is mechanical: an overflow valve 4 is installed on the spindle hydraulic line. When the spindle pressure exceeds the overflow pressure, the valve opens, allowing the spindle to descend rapidly. This quickly increases the discharge port, allowing foreign objects to pass through quickly and reducing damage to the equipment.
[0087] Furthermore, those skilled in the art will understand that although some embodiments described herein include certain features found in other embodiments but not others, combinations of features from different embodiments are also within the scope of protection of this invention and form different embodiments. For example, in the embodiments described above, those skilled in the art can use them in combination based on known technical solutions and the technical problems to be solved by this application.

A method for monitoring and adjusting the discharge port of a cone motor, characterized in that, The cone motor discharge port monitoring and adjustment system according to any one of claims 1-5 includes the following steps: (1) Monitoring phase S1. Start the feeder and cone motor. The feeder continuously feeds material to make the cone motor work at full capacity. The average pressure of the cone motor in the first five minutes before it starts working at full capacity is used as the maintenance pressure at the outlet. The average power of the cone motor in the first five minutes before it starts working at full capacity is used as the maintenance power. S2. Select the host real-time power fuzzy control mode based on the maintenance power, the fuzzy control mode based on the setting of a single discharge port, or the control mode based on the setting of multiple discharge ports through the control mode on the instrument. S3. When in the real-time power fuzzy control mode of the host, if the host average power is detected to be greater than the maintenance power for one minute for a continuous period of one minute, or if the host average power is greater than the maintenance power * 140% more than 10 times within one minute, it is determined that the discharge port is reduced; if the host average power is detected to be less than the maintenance power for five consecutive minutes, it is determined that the discharge port is increased. When in fuzzy control mode based on a single discharge port, if the average spindle pressure is greater than the holding pressure for two consecutive minutes, or the average spindle pressure is greater than 150% of the holding pressure for five consecutive minutes more than 10 times, the discharge port is determined to decrease; if the average spindle pressure is less than the holding pressure for five consecutive minutes, the discharge port is determined to increase. When in the control mode based on multiple discharge ports, the discharge ports are adjusted according to the working time. (2) Adjustment phase When the discharge port is determined to decrease, the control cylinder lowers; when the discharge port is determined to increase, the control cylinder rises.
7. The method for monitoring and adjusting the discharge port of a conical main machine according to claim 6, characterized in that, When it is determined that the discharge port is reduced, the main shaft hydraulic motor is reversed by controlling the main shaft hydraulic motor to reverse the hydraulic pump, so that the main shaft cylinder drops by 1mm or the dropping action lasts for 1 second, and the motor rotation is stopped. When the discharge port is determined to be enlarged, the hydraulic motor of the main shaft is controlled to rotate forward, which drives the hydraulic pump to rotate forward, causing the main shaft cylinder to rise by 1mm or the rising action to last for 1 second, and then the motor rotation is stopped.
