It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only portions relevant to the relevant utility model are shown in the accompanying drawings.

[0053] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] Figure 1 The lubrication system of a single-cylinder hydraulic cone crusher of the present application is shown, comprising:

[0055] Lubricating oil tank 1, the lubricating oil tank 1 is connected to the oil inlet of the crusher 20 through the oil inlet line 11, and the lubricating oil tank 1 is connected to the oil return port of the crusher 20 through the oil return line 12;

[0056] A gear pump 2, wherein the inlet end of the gear pump 2 is connected to the lubricating oil tank 1, and the outlet end of the gear pump 2 is connected to the oil inlet of the crusher 20;

[0057] Filter assembly, the filter assembly is provided in the oil inlet line 11 and the oil return line 12;

[0058] Pressure assembly 4, which is provided on the oil inlet line 11 between the gear pump and the crusher;

[0059] The temperature sensing component includes an oil return temperature sensing unit 51, an oil inlet temperature sensing unit 52 and a lubricating oil tank temperature sensing unit 53; the oil return temperature sensing unit 51 is provided in the oil return line 12, the oil inlet temperature sensing unit 52 is provided in the oil inlet line 11, and the lubricating oil tank temperature sensing unit 53 is provided in the lubricating oil tank 1;

[0060] The temperature control component is arranged at the oil inlet line 11 and the oil return line 12; the temperature control component is electrically connected to the temperature sensing component.

[0061] The present invention effectively prevents equipment damage caused by excessively high oil temperature or abnormal oil pressure by monitoring oil temperature and oil pressure in real time and automatically adjusting the oil temperature. Furthermore, the present invention, through the coordinated use of temperature control components and temperature sensing components, can precisely control the oil temperature, maintain the optimal viscosity of the lubricating oil, improve the lubrication effect, and reduce equipment wear. Furthermore, the present invention automatically adjusts the oil temperature, enabling the equipment to adapt to different operating environment temperatures, thereby increasing the range of use of the equipment. Furthermore, the present invention simplifies oil level monitoring and filter maintenance through the use of a liquid level gauge, a filter blockage indicator, and a return oil filter and return oil filter magnet, thereby reducing maintenance costs.

[0062] In a preferred embodiment, the motor 21 provides power to drive the gear pump 2 to operate, thereby achieving the delivery of lubricating oil. This configuration allows precise control of the speed and flow of the oil pump to meet the needs of the system.

[0063] In a preferred embodiment, the temperature control assembly includes a heater 61 and an air cooler 62; the heater 61 is provided on the lubricating oil tank 1, and a cooling fan 61 is also provided on the oil inlet line 11. The heater 61 is mounted on the lubricating oil tank 1 and can directly heat the oil in the tank. Furthermore, in low-temperature environments, the heater 61 can increase the temperature of the lubricating oil, ensuring its fluidity and lubricating effect, and preventing equipment startup difficulties or insufficient lubrication due to excessively low oil temperatures. The air cooler 62 is mounted on the oil inlet line 11 and cools the lubricating oil flowing to the crusher 20. In high-temperature environments, the air cooler 52 can lower the temperature of the lubricating oil, preventing deterioration of the lubricating oil or equipment overheating due to excessively high oil temperatures.

[0064] In a preferred embodiment, a one-way valve is further provided between the oil inlet 11 and the oil inlet of the crusher 20, so that when the pumping pressure of the gear pump 2 is insufficient, the connection between the crusher 20 and the lubricating oil tank 1 is disconnected to prevent the lubricating oil from flowing back into the lubricating oil tank 1.

[0065] In a preferred embodiment, the oil return temperature sensing unit 51 is provided in the oil return line 12. Figure 1 As shown, it is specifically arranged between the thermometer 511 and the return oil port; the return oil temperature sensing unit 51 is used to monitor the temperature of the lubricating oil. When the oil temperature of the return oil circuit 12 reaches the set value (the set value is 60°C under normal working conditions, the set value is 65°C under high temperature working conditions, and the set value is 52°C under low temperature working conditions), the corresponding protection mechanism will be triggered, such as shutting down the gear pump 2 to prevent equipment damage due to excessively high oil temperature.

[0066] In addition, the oil inlet temperature sensing unit 52 is provided in the oil inlet passage 11. Figure 1As shown, it is specifically arranged between the gear pump 2 and the oil inlet filter assembly 31; when the oil inlet temperature sensing unit 52 detects that the oil temperature of the oil inlet circuit 11 reaches the set value (the set value is 42°C under normal working conditions, the set value is below 47°C under high temperature working conditions, and the set value is below 35°C under low temperature working conditions), the cooling fan 61 will be started to reduce the oil temperature to ensure that the crusher operates at an appropriate temperature.

[0067] In addition, the lubricating oil tank temperature sensing unit 53 is provided in the lubricating oil tank 1, which can accurately sense the temperature of the lubricating oil tank 1; and when the lubricating oil tank temperature sensing unit 53 monitors the return oil temperature, when the return oil temperature reaches the set value (the set value is 27°C under normal working conditions, the set value is 32°C under high temperature working conditions, and the set value is 18°C ​​under low temperature working conditions), it will trigger an alarm or the auxiliary control system to take corresponding measures.

[0068] In a preferred embodiment, Figure 1 As shown, the filter assembly includes an inlet filter assembly 31 and a return filter assembly (not shown). The inlet filter assembly 31 is located on the oil inlet line 11 between the lubricating oil tank 1 and the crusher 20. The return filter assembly is located on the return line between the temperature sensing assembly and the lubricating oil tank 1. Specifically, the inlet filter assembly 31 filters the lubricating oil flowing from the lubricating oil tank 1 to the crusher 20, ensuring that the lubricating oil entering the crusher is clean, reducing equipment wear and improving equipment operating efficiency. The return filter assembly filters the lubricating oil returning from the crusher to the lubricating oil tank 1, removing impurities and wear particles that may be generated during the circulation process, thereby maintaining the cleanliness of the lubricating oil.

[0069] In a preferred embodiment, the oil inlet filter assembly 31 includes a first oil inlet filter 311 and a second oil inlet filter 312. The first oil inlet filter 311 is located on the oil inlet line 11 between the gear pump 2 and the lubricating oil tank 1. The first oil inlet filter 311 performs preliminary filtration of the lubricating oil flowing out of the gear pump 2, removing any large particles and impurities that may be present, thereby protecting the lubricating oil tank 1 and the internal components of the crusher 20. The second oil inlet filter 312 performs a secondary filtration of the lubricating oil that has passed through the first oil inlet filter 311, ensuring that the lubricating oil entering the crusher 20 is even cleaner, further reducing equipment wear.

[0070] In a preferred embodiment, Figure 1 As shown, the second oil inlet filter 312 is provided on the oil inlet line 11 between the gear pump 2 and the oil inlet of the crusher 20. The second oil inlet filter 312 finely filters the lubricating oil flowing out of the gear pump 2 to ensure that the lubricating oil entering the crusher 20 is as clean as possible, reducing wear and potential damage to the internal components of the crusher.

[0071] In a preferred embodiment, Figure 1As shown, the pressure assembly 4 includes a pressure switch 41 and a pressure gauge 42; the pressure switch 41 is electrically connected to the gear pump 2; so that when the pressure switch 41 is triggered, the motor 21 of the gear pump 2 can be urgently stopped to avoid the impact of excessive pressure on the pipeline, etc.; the pressure gauge 42 is connected to the oil inlet line 11 between the second oil inlet filter 312 and the oil inlet of the crusher 20.

[0072] In a preferred embodiment, Figure 1 As shown, the second oil inlet filter 312 is connected to a filter clogging indicator 312a. This indicator 312a is used to monitor the clogging status of the second oil inlet filter 312. When impurities accumulate in the filter to a certain level (this level can be preset based on actual testing needs), affecting filtration efficiency or causing a decrease in flow rate, the indicator will issue an alarm or signal.

[0073] Specifically, the detection of the degree of blockage is generally carried out through the following existing technologies, such as pressure difference detection, flow detection, resistance or capacitance change, etc.; Pressure difference detection: The blockage indicator 321a measures the pressure difference between the inlet and outlet of the filter 312. When the pressure difference exceeds the preset value, it indicates that the filter 312 may have been blocked to a certain extent and needs to be cleaned or replaced. Flow detection: The degree of blockage is determined by monitoring the flow change of the filter 312. If the flow rate drops below a certain threshold, it may mean that the filter 312 is blocked by impurities. Resistance or capacitance change: This type of blockage indicator 312a will detect the resistance or capacitance change of impurities in the filter; when the impurities accumulate to a certain extent, the change in resistance or capacitance will trigger an alarm.

[0074] In a preferred embodiment, Figure 1 As shown in the figure, the lubricating oil tank is also equipped with a liquid level gauge, which can display the oil level in the tank in real time, so that the operator can intuitively understand the oil level.

[0075] In a preferred embodiment, Figure 1 As shown, the lubricating oil tank 1 is also equipped with a return oil filter 13 and a return oil filter magnet 14. Filtering Impurities: The return oil filter 13 is used to filter impurities and particles from the lubricating oil returning from the equipment to the lubricating oil tank 1. These impurities may include wear metal, dust, and other contaminants. Protecting Equipment: By removing large particles from the oil, the return oil filter 13 helps protect the equipment's bearings, gears, and other moving parts, reducing wear. Extending Oil Life: Clean oil reduces oil contamination, extending the lubricating oil's service life and reducing replacement frequency.

[0076] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
