[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] In this way, by setting up a coal gangue mixing degree identification device to monitor and analyze the attenuation law of dual-energy gamma rays in real time, this utility model can quickly and automatically identify the coal gangue mixing degree of the coal gangue discharged from the top coal caving equipment, effectively improving the identification efficiency of coal gangue mixing degree. It solves the problem that the existing technology cannot identify the coal gangue mixing degree with high precision and efficiency by manual means, reduces the intensity of manual labor, reduces the time required to identify the coal gangue mixing degree, improves work efficiency, increases coal output and quality, reduces resource waste, and enhances the economic benefits of coal mines.

[0028] In use, the coal gangue mixing degree identification device of this utility model has a gamma ray source 1 and a receiving probe 2 mounted opposite each other on a scraper conveyor. The gamma ray source 1 is controlled to emit dual-energy gamma rays to the receiving probe 2, and the dual-energy gamma rays pass through the coal gangue mixture on the scraper conveyor. The main control unit is used to monitor the gamma ray source 1 and the receiving probe 2, and to analyze and process the monitoring information. By observing the attenuation pattern of the dual-energy gamma rays as they pass through the coal gangue mixture on the scraper conveyor, the device can confirm whether the coal content in the coal gangue mixture meets the predetermined standard.

[0029] like Figure 2 As shown, the coal gangue mixing degree identification device includes a control cabinet 6, which includes a cabinet body 60, and the control host is installed inside the cabinet body 60.

[0030] In this way, the control cabinet not only protects the control host but also provides convenience for the operation of the coal gangue mixing degree identification device, ensures its stability and safety, simplifies its operation process, greatly reduces its failure rate, improves its reliability and maintenance efficiency, and reduces downtime during coal mine production. This ensures continuous and stable production in the coal mine and makes it suitable for use in various harsh environments, such as underground and open-pit coal mines, effectively guaranteeing the normal operation of the coal gangue mixing degree identification device and the safety of personnel.

[0031] like Figure 2As shown, the control cabinet 6 also includes: an input device 61, which is mounted on the cabinet 60 and electrically connected to the control host for input settings; a display control component 62, which is mounted on the cabinet 60 and electrically connected to the control host for providing display support and operation settings; and a heat dissipation window 63, which is mounted on the cabinet 60 for ventilation and heat dissipation of the components installed inside the control cabinet 6. This allows operators to monitor the operating status of the coal gangue mixing degree identification device at any time, adjust its parameters promptly, improve the flexibility and efficiency of the device's operation, and reduce the labor intensity of operators.

This intuitive display and operation interface simplifies the use of the coal gangue mixing degree identification device, reduces operator training costs, and is suitable for workers of varying skill levels on coal production lines. This design allows operators to operate the device without specialized training, significantly reducing labor costs in coal mines. It also improves the efficiency of the coal gangue mixing degree identification device, ensures stable equipment operation, and is suitable for coal mines of all sizes, from large to small.

The display control component 62 is located above the heat dissipation window 63, and the input device 61 is located between the display control component 62 and the heat dissipation window 63. This layout design optimizes the operation process, reduces the movement range of operators, and improves operational efficiency. Especially in the space-constrained underground environment of coal mines, it can effectively save space, improve the utilization rate of the work area, and achieve maximum effect even in the space-constrained underground environment of coal mines. It improves the utilization rate of underground working space in coal mines, reduces the operating costs of coal mines, and is particularly suitable for underground operations in coal mines. It can achieve efficient operation of equipment while reducing safety hazards in underground coal mines.

[0034] like Figure 1As shown, the coal gangue mixing degree identification device also includes a protective component 5, which is installed above the gamma ray source machine 1 to provide protection for the gamma ray source machine 1, prevent damage to the gamma ray source machine 1 from the external environment, improve the service life of the gamma ray source machine 1, ensure the long-term stable operation of the coal gangue mixing degree identification device, and reduce the maintenance cost of the coal gangue mixing degree identification device. It is particularly suitable for the production environment of coal mines, can realize the efficient operation of the equipment, and at the same time reduce the operating cost of coal mines.

[0035] like Figure 1 As shown, the coal gangue mixing degree identification device also includes a heat dissipation component 4. The heat dissipation component 4 is located above the gamma ray source machine 1 and within the protective space of the protective component 5 to effectively prevent the equipment from overheating, ensuring the long-term stable operation of the coal gangue mixing degree identification device, reducing the failure rate of the coal gangue mixing degree identification device, and improving the efficiency of the coal gangue mixing degree identification device. It is particularly suitable for automated production lines in coal mines, enabling efficient operation of the equipment while reducing the operating costs of coal mines.

[0036] like Figure 1 As shown, the heat dissipation component 4 includes a heat dissipation body 41 and two sets of heat dissipation fins 42 located on opposite sides of the heat dissipation body 41.

[0037] like Figure 1 As shown, the protective component 5 includes two side supports 51 spaced apart along a first direction and a plurality of top rods 52 located between the two side supports 51. The lower ends of the two side supports 51 are connected to the top of the gamma ray source machine 1. The plurality of top rods 52 are spaced apart along a second direction. Each top rod 52 extends along the first direction, and both ends of each top rod 52 are respectively connected to the upper ends of the two side supports 51 to form a protective space. The first direction and the second direction are perpendicular to each other.

[0038] This not only provides physical protection but also enhances the structural stability of the coal gangue mixing degree identification device, making it suitable for the installation and use of coal sorting equipment, especially in environments where the equipment needs to withstand large external forces, such as vibration and impact on scraper conveyors.

[0039] like Figure 1 As shown, each side support 51 includes two columns 511 and a crossbar 512 located between the two columns 511. The two columns 511 are spaced apart along the second direction. The two ends of the crossbar 512 are respectively connected to the two columns 511. One end of each top rod 52 is connected to the crossbar 512.
