Description

Technical Field

[0001] The present invention relates to the technical field of coal mining, and in particular to an unmanned open-pit mining device suitable for use in extreme environments. Background Art

[0002] Unmanned open-pit mining is a method of extracting mineral resources using advanced information technology, communications technology, and automated equipment. It fully automates the mining process through technologies such as unmanned mining vehicles, intelligent dispatching systems, and cloud-based monitoring platforms. In this unmanned open-pit mining system, vehicles can autonomously plan routes, identify obstacles, and perform loading, transport, and unloading tasks. They can also collaborate with other equipment such as excavators and bulldozers. This mining method not only significantly improves operational safety, especially in hazardous environments or extreme weather conditions, but also increases efficiency by optimizing route planning and reducing downtime.

[0003] Open-pit mining inevitably generates large amounts of dust due to operations such as blasting, drilling, loading, and transportation. Especially in dry climates, this dust can quickly disperse and become suspended in the air, forming a thick dust cloud. This dust can cling to surveillance camera lenses, gradually blurring the camera's field of view over time and reducing image clarity. Furthermore, dust particles in the air scatter light, causing haziness or halos in video footage, which impairs the camera's ability to capture detail. This poses challenges for autonomous vehicles in identifying obstacles, determining material location, and performing precise maneuvers. Summary of the Invention

[0027] See also Figures 1 to 7 The present invention provides an unmanned open-pit mining device suitable for use in extreme environments, comprising a crawler-type mobile structure 101, a support base 102, and a conveying assembly, wherein the support base 102 is arranged on the crawler-type mobile structure 101, and the conveying assembly comprises a scraper 103, a first conveyor belt 104, and a second conveyor belt 105, wherein the scraper 103 is arranged on one side of the support base 102, the first conveyor belt 104 is arranged on one side of the scraper 103, and the second conveyor belt 105 is arranged on one side of the first conveyor belt 104. The present invention also includes a monitoring assembly and a cleaning assembly, wherein the monitoring assembly comprises a support frame 106, a rotating motor 107, a rotating rod 108, a monitor 109, and a protective cover 110. The support frame 106 is arranged on the support base 102, the rotating rod 108 is rotatably arranged on the support frame 106, the output end of the rotating motor 107 is connected to the rotating rod 108, the monitor 109 is arranged on the rotating rod 108, and the protective cover 110 is arranged on the outside of the monitor 109; the cleaning assembly includes a control cylinder 111, a cleaning shell 112, a liquid inlet 113 and a rotating cleaner 114, the control cylinder 111 is arranged on the rotating rod 108, the cleaning shell 112 is fixed on the output end of the control cylinder 111, the liquid inlet 113 is connected to the cleaning shell 112, and the rotating cleaner 114 is arranged in the cleaning shell 112.

[0028] In this embodiment, the scraper 103 is arranged on one side of the support base 102, and is used to push the scattered or loose mineral materials on the ground to the top of the first conveyor belt 104; the first conveyor belt 104 further receives the materials conveyed by the scraper 103 and transfers them to the second conveyor belt 105; the second conveyor belt 105 serves as the main conveying structure, responsible for transporting the collected minerals to the designated stockpiling area or other subsequent processing equipment.

[0029] Support frame 106 is fixedly mounted on support base 102, providing a stable support foundation for the entire monitoring system. Rotating rod 108 is rotatably mounted on support frame 106 via a bearing structure, and the output end of rotating motor 107 is connected to rotating rod 108, allowing rotating rod 108 to rotate horizontally. Monitor 109, mounted at the end of rotating rod 108, can collect real-time image data around the mining area, assisting the unmanned driving system in completing functions such as path planning, obstacle identification, and operating status monitoring. Protective cover 110 covers the outside of monitor 109, providing dust, water, and impact protection.

[0030] When dust accumulates on the protective cover 110, reducing its visibility, the rotating rod 108 can be rotated 180°, causing the protective cover 110 to face upward. The control cylinder 111 is then controlled to move, driving the cleaning shell 112 closer to the protective cover 110, thereby forming a sealed cleaning space. Cleaning fluid is then introduced into the cleaning space via the liquid inlet 113, and the rotating cleaner 114 is activated to clean the surface of the protective cover 110. After cleaning is complete, the cleaning shell 112 is moved upward, and the cleaning fluid is discharged under the action of gravity. The protective cover 110 is then reset and reused, allowing continuous operation in dusty environments and reducing manual maintenance frequency and operating costs.

[0031] The support frame 106 includes a movable frame 115, a support frame body 116 and a movable screw 117. The support frame body 116 is fixed on the support base 102. The movable frame 115 is slidably set on the support frame body 116. The movable screw 117 is threadedly connected to the movable frame 115 and is rotatably connected to the support frame body 116. The rotating rod 108 is rotatably set on the movable frame 115.

[0032] The support frame body 116 is fixedly mounted on the support base 102 and serves as the basic bearing structure of the entire monitoring assembly, with good stability and vibration resistance. The mobile frame 115 is slidably arranged on the support frame body 116 through a guide rail or a slide groove structure, so that it can be adjusted left and right in the vertical direction or within a set angle range, thereby realizing flexible adjustment of the monitoring position of the monitor 109 to obtain more image information. The moving screw 117 is connected to the mobile frame 115 by a threaded connection, and one end of the moving screw 117 is rotatably connected to the support frame body 116 through a bearing, so that when the moving screw 117 is rotated, the mobile frame 115 can be driven to move smoothly along the guide structure on the support frame body 116. In addition, one end of the rotating rod 108 is rotatably arranged on the mobile frame 115 through a rotating support or a slewing bearing, allowing it to rotate freely in a vertical plane.

[0033] The monitor 109 includes a data transmission unit, a data processing unit and a monitoring camera. The monitoring camera is used to obtain monitoring images. The data processing unit is used to process the monitoring images and obtain processed images. The data transmission unit is used to transmit the processed images to the host computer.

[0034] As the core sensing component, the surveillance camera is responsible for collecting high-definition image information of the mining operation area in real time. It has a wide-angle field of view, night vision capability, and dust and water resistance. It can operate stably in complex environments such as strong light, low illumination, and high humidity.

[0035] The collected raw image data is first fed into a data processing unit, which incorporates a high-performance image processing chip or AI algorithm module. This unit performs various image processing operations, including noise reduction, enhancement, edge detection, and object recognition, thereby extracting more valuable information and generating an optimized processed image. This process not only improves image clarity and usability but also effectively reduces the amount of invalid data, alleviating the pressure on subsequent data transmission.

[0036] The processed image information is then sent to the host computer system via a data transmission unit. This unit supports both wired and wireless communication methods, such as 5G, Wi-Fi 6, or specialized industrial Ethernet protocols, ensuring high-speed, stable remote transmission of image data even in extreme environments. The host computer can then use the received images for real-time display, intelligent analysis, and remote control decision-making, significantly enhancing the visualization and intelligence of the unmanned mining equipment.

[0037] The monitoring assembly further includes a sealing plate 121 , which is fixed to one side of the protective cover 110 and is configured to contact the cleaning shell 112 .

[0038] The monitoring assembly also includes a sealing plate 121, which is fixedly mounted on one side of the protective cover 110 and is designed to be in close contact with the cleaning shell 112. When the cleaning assembly is activated, the cleaning shell 112 approaches the lens area of the monitor 109 to perform a cleaning operation. The sealing plate 121 acts as an auxiliary seal during this process, preventing dust, moisture, or other contaminants from entering the interior through the gap between the protective cover 110 and the cleaning shell 112, thereby ensuring the safe and stable operation of the electronic components within the monitor 109.

[0039] The monitoring assembly further includes an auxiliary support block 122 , which is fixed to the moving frame 115 and is used to limit the rotation angle of the rotating rod 108 .

[0040] Furthermore, to enhance the controllability and safety of the rotating rod 108 during rotation, the monitoring assembly is equipped with an auxiliary support block 122, which is fixedly connected to the mobile frame 115 and located near the rotation path of the rotating rod 108. Its primary function is to physically limit the maximum rotation angle of the rotating rod 108, preventing motor loss of control or mechanical overspeed from causing the monitor 109 to deviate from its normal operating range, potentially leading to equipment damage. The auxiliary support block 122 also serves as a buffer structure, providing a certain degree of shock absorption protection at extreme positions, thereby extending the service life of the rotating mechanism.

[0041] The cleaning shell 112 includes a cleaning shell body 123, a sealing ring 124, an elastic member 125 and a nozzle 126. The cleaning shell body 123 is fixed on the output end of the control cylinder 111. A cleaning hole is provided on the cleaning shell body 123. The sealing ring 124 is slidably provided in the cleaning shell body 123 for sealing the cleaning hole. The nozzle 126 is provided on one side of the cleaning shell body 123.

[0042] The cleaning housing 123 is fixedly mounted on the output end of the control cylinder 111 and serves as the primary support structure for the entire cleaning assembly. Made of high-strength, corrosion-resistant materials, it offers excellent impact resistance and environmental adaptability, capable of withstanding the harsh conditions common in mining areas, such as dust, moisture, and high or low temperatures. A cleaning hole is defined in the cleaning housing 123, located corresponding to the protective cover 110.

[0043] The sealing ring 124 is arranged around the cleaning hole. When the rotary cleaner 114 is not working, the sealing ring 124 is tightly attached to the edge of the cleaning hole under the action of the elastic member 125, forming a sealing barrier; and when the control cylinder 111 pushes the cleaning shell 112 close to the monitor 109 lens, the sealing ring 124 will be acted upon by the protective cover 110 to shrink inward, thereby making way for the cleaning hole, so that the liquid can enter the cleaning shell body 123 for cleaning.

[0044] The elastic member 125 is usually a spring or rubber buffer structure, one end of which is fixed to the inner wall of the cleaning shell body 123 and the other end is connected to the sealing ring 124. Its main function is to provide a reset force for the sealing ring 124.

[0045] A nozzle 126 is further provided on one side of the cleaning shell body 123 , and the nozzle 126 can spray water to the outside to reduce floating dust near the mining device.

[0046] The liquid inlet 113 includes a liquid tank 127 , a connecting pipe 128 and a liquid inlet valve 129 . The liquid inlet valve 129 is connected to the cleaning shell body 123 . The connecting pipe 128 is connected to the liquid inlet valve 129 . The liquid tank 127 is connected to the connecting pipe 128 .

[0047] Liquid tank 127, a storage container for cleaning fluid, is fixedly mounted on support base 102 or a structure near cleaning housing 112. It can store a certain amount of cleaning fluid, such as deionized water, dust-proof liquid, or specialized optical cleaner. Liquid tank 127 is constructed of corrosion-resistant and age-resistant materials and features a strong seal to prevent leakage and contamination.

[0048] One end of the connecting tube 128 is connected to the liquid inlet valve 129 provided on the cleaning housing body 123, and the other end extends into the interior of the liquid tank 127, forming a liquid circulation channel. The connecting tube 128 is generally made of a flexible pressure-resistant hose, which has good flexibility and vibration resistance, can adapt to the displacement changes of the cleaning component during movement, and has a certain degree of chemical corrosion resistance to extend the service life.

[0049] The inlet valve 129, mounted on the cleaning housing 123 and connected to the nozzle 126, is a key component for controlling the flow of cleaning fluid. Driven by a control system, this valve precisely controls opening and closing times and flow rate according to cleaning needs, ensuring on-demand liquid supply and minimizing waste. A filter or electromagnetic control mechanism is incorporated into the inlet valve 129 to prevent impurities from entering the nozzle 126 and causing blockage, while also enabling rapid opening and closing, improving response speed and cleaning efficiency.

[0050] The rotating cleaner 114 includes a ring gear 130, a gear 131, a cleaning motor 132, a planetary gear 133 and a cleaning roller 134. The ring gear 130 is rotatably arranged in the cleaning shell body 123, the gear 131 is engaged with the ring gear 130, the output end of the cleaning motor 132 is connected to the gear 131, the planetary gear 133 is engaged with the ring gear 130, and the cleaning roller 134 is fixed to the planetary gear 133.

[0051] The ring gear 130 is an annular structure that is fixedly or rotatably arranged inside the cleaning shell body 123. Its inner wall is provided with continuous tooth grooves for engaging with other transmission components. The gear 131 is engaged with the ring gear 130 and is located inside it. As an active transmission component, it is driven by a cleaning motor 132 installed on the cleaning shell 112. The output shaft of the cleaning motor 132 is connected to the central axis of the gear 131 through a coupling or a direct connection mode. When the motor is started, the gear 131 is driven to rotate, thereby driving the ring gear 130 to rotate.

[0052] Furthermore, the planetary gears 133 are distributed on the periphery of the gear 131 and mesh with the ring gear 130 to form a typical planetary transmission mechanism. When the ring gear 130 rotates, it can drive the planetary gears 133 to rotate and rotate around the center at the same time. The cleaning roller 134 is fixedly mounted on the corresponding planetary gear 133 and rotates with the planetary gear 133. The surface of the cleaning roller 134 is made of soft and wear-resistant material (such as rubber, a brush or a composite cleaning cloth), which can effectively remove dust, oil and water stains on the surface of the lens without causing scratches or other damage to the lens. As the planetary gear 133 revolves around the center and rotates, the cleaning roller 134 can form a multi-point contact, spiral wiping cleaning track on the surface of the protective cover 110, significantly improving the cleaning coverage and efficiency.

[0053] The cleaning assembly further includes a connecting valve 135 , a heater 136 and an air inlet pipe 137 . The connecting valve 135 is connected to the cleaning shell body 123 , the heater 136 is in communication with the connecting valve 135 , and the air inlet pipe 137 is in communication with the heater 136 .

[0054] The cleaning component further includes a filter 138 , which is disposed at the air inlet of the air inlet pipe 137 .

[0055] The connecting valve 135 is fixedly mounted on the cleaning housing body 123 and serves as a gas flow control interface for connecting an external gas source or an internal circulating gas path with the interior of the cleaning housing 112. The connecting valve 135 has excellent sealing performance and fast response characteristics, and can accurately control the gas flow according to the control system instructions, ensuring the efficient operation of the drying and purging functions during the cleaning operation. This can remove residual moisture from the protective cover 110 after cleaning, reducing the possibility of dust adhesion.

[0056] Connected to the connecting valve 135 is a heater 136, one end of which is connected to the connecting valve 135 and the other end is connected to the air inlet pipe 137. The heater 136 is provided with a heating wire or a PTC ceramic heating element inside, which can quickly heat the air flowing through it to a set temperature after being powered on.

[0057] Air inlet pipe 137 serves as a gas introduction channel. One end of the pipe is connected to heater 136, and the other end extends to the external environment or the system's internal air supply module, responsible for introducing ambient air or compressed air into the system. Made of a high-temperature, aging-resistant flexible material, air inlet pipe 137 offers excellent airtightness and structural stability, adapting to the complex vibration and temperature fluctuations in mining areas.

[0058] To further improve the quality of incoming air and prevent dust, particulate matter, or other impurities from entering the cleaning housing 112 with the airflow, thereby affecting the cleaning effect or damaging the components of the monitor 109, the cleaning assembly is further provided with a filter 138, which is disposed at the air inlet of the air inlet pipe 137. Filter 138 is typically composed of a multi-layer filter structure, including a primary dust filter, an activated carbon adsorption layer, and a high-efficiency HEPA filter element. It can effectively remove dust, oil mist, and harmful gases suspended in the air, ensuring the cleanliness of the air entering the heater 136 and the cleaning housing 112, thereby extending the service life of the equipment and improving cleaning reliability.
