[0028] 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.

[0029] like Figure 1 and Figure 2 As shown, this utility model provides a coal gangue mixing degree identification device, including: a mounting frame 1, which is installed above a scraper conveyor 7; an image acquisition component 2, which is installed on the mounting frame 1, with its acquisition probe facing the scraper conveyor 7; a cleaning component 3, which is movably disposed on the image acquisition component 2 and located on the side of the image acquisition component 2 closer to the scraper conveyor 7, for cleaning the acquisition probe; a data acquisition unit, which is electrically connected to the image acquisition component 2, for receiving, analyzing, and processing the image information acquired by the image acquisition component 2 to obtain result information; and a control host, which is electrically connected to the image acquisition component 2, the cleaning component 3, and the data acquisition unit, for controlling the working status of the image acquisition component 2, the cleaning component 3, and the data acquisition unit, and determining whether to control the top coal caving equipment to operate based on the result information from the data acquisition unit.

[0030] Thus, this invention, by incorporating a coal gangue mixing degree identification device, can quickly and automatically identify the coal gangue mixing degree of the coal gangue discharged from the top coal caving equipment. This solves the problem in existing technologies where manual identification of coal gangue mixing degree is difficult and inefficient, reducing labor intensity, shortening the time required for identification, improving the working efficiency of the top coal caving equipment, and increasing the mining efficiency and utilization rate of coal resources. It is suitable for various coal mining environments, especially under conditions of thin coal seams and large variations in coal gangue mixing degree, effectively reducing resource waste and avoiding over-mining or under-mining, thereby ensuring the rational utilization of coal resources. Furthermore, the inclusion of the cleaning component 3 allows the coal gangue mixing degree identification device of this invention to operate stably in harsh environments, improving the safety and continuity of coal mining.

[0031] Specifically, the control host can provide corresponding feedback based on the results. When the control host identifies that the coal content in the coal gangue mixture is low, the control host will send the corresponding control information to the service terminal to control the top coal caving equipment to operate.

[0032] In the coal gangue mixing degree identification device of this utility model, the image acquisition component 2 includes a camera, and the cleaning component 3 includes a windshield wiper.

[0033] like Figure 2 As shown, the coal gangue mixing degree identification device includes a control cabinet 6, which includes a cabinet body 60. The data acquisition unit and the control host are both installed inside the cabinet body 60.

[0034] This not only protects the data acquisition unit and control host from the harsh environment and reduces the exposed area of ​​the coal gangue mixing degree identification device in the underground environment, thus extending the service life of the coal gangue mixing degree identification device, but also facilitates the maintenance and management of the data acquisition unit and control host, ensuring the stable operation of the coal gangue mixing degree identification device.

[0036] Specifically, the glass window 61 is embedded in the front of the cabinet 60 so that the operator can view the components installed inside the control cabinet 6 through the glass window 61 without having to open the cabinet 60, thus reducing the risk of manual operation; the display control component 62 is also embedded in the front of the cabinet 60 and located below the glass window 61 to provide display support and operation settings.

[0037] Preferably, there are two heat dissipation windows 63, which are respectively set on the left and right sides of the cabinet 60 to ventilate and dissipate heat for the components installed in the control cabinet 6. This solves the heat dissipation problem of the control cabinet 6 in high temperature environment, avoids failure caused by overheating of the control cabinet 6, ensures the stable operation of the control cabinet 6 under high temperature and high humidity conditions, and improves the continuity and safety of coal mining.

[0038] like Figure 2As shown, the display control component 62 includes: a display screen 621, which is mounted on the cabinet 60 and located below the glass window 61, and is electrically connected to the control host to provide display support; and a control button 622, which is mounted on the cabinet 60 and located below the display screen 621, and is electrically connected to the control host for operation and settings by pressing the control button 622. This enables rapid adjustment of the parameters of the coal gangue mixing degree identification device, reduces the operator's workload, improves the response speed and operating efficiency of the coal gangue mixing degree identification device, and is suitable for the rapidly changing underground coal mine operating environment, thereby enhancing the flexibility and safety of coal mining.

[0039] like Figure 1 As shown, the coal gangue mixing degree identification device also includes a protective component 5, which is installed on the mounting frame 1 and located above the image acquisition component 2. The protective component 5 provides protection for the image acquisition component 2, avoids damage to the image acquisition component 2 caused by the external environment, improves the service life of the image acquisition component 2, and ensures the accuracy and reliability of the image acquisition process. It is suitable for various harsh environments in underground coal mines and ensures the continuity and safety of coal mining.

[0040] like Figure 1 As shown, the coal gangue mixing degree identification device also includes a shock-absorbing connector 4, with both ends of the connector 4 connected to the mounting frame 1 and the protective component 5, respectively. This reduces damage to the coal gangue mixing degree identification device caused by vibration, improves the operator's working comfort, ensures long-term stable operation of the device, and reduces the maintenance frequency of the device.

[0041] like Figure 1 As shown, the shock-absorbing connector 4 is located above the mounting frame 1. The shock-absorbing connector 4 includes an elastic buffer 41 and two connecting posts 42 that are respectively connected to both ends of the elastic buffer 41. The two connecting posts 42 are respectively connected to the mounting frame 1 and the protective component 5.

[0042] Specifically, the elastic buffer 41 includes a spring.

[0043] like Figure 1 As shown, the protective component 5 includes a top plate 51 and two inclined side plates 52 located at both ends of the top plate 51. The top plate 51 is connected to the mounting bracket 1. The upper ends of the two inclined side plates 52 are connected to the top plate 51. The lower ends of the two inclined side plates 52 are located on the side of the top plate 51 closer to the scraper conveyor 7. The distance between the two inclined side plates 52 gradually increases along the direction closer to the scraper conveyor 7.

[0044] like Figure 1As shown, the mounting frame 1 includes two columns 11 spaced apart and a middle crossbar 12 located between the two columns 11. The two ends of the middle crossbar 12 are respectively connected to the upper ends of the two columns 11, and the lower ends of the two columns 11 are respectively connected to the opposite sides of the scraper conveyor 7; wherein, the image acquisition component 2 is installed on the middle crossbar 12.

[0045] Specifically, the shock-absorbing connector 4 is installed on the intermediate crossbar 12, and the top plate 51 of the protective component 5 is located on the side of the shock-absorbing connector 4 away from the intermediate crossbar 12.

[0046] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0047] The coal gangue mixing degree identification device of this utility model includes: a mounting frame 1, which is installed above the scraper conveyor 7; an image acquisition component 2, which is installed on the mounting frame 1, with the acquisition probe of the image acquisition component 2 facing the scraper conveyor 7; a cleaning component 3, which is movably disposed on the image acquisition component 2 and located on the side of the image acquisition component 2 closer to the scraper conveyor 7, for cleaning the acquisition probe; a data acquisition unit, which is electrically connected to the image acquisition component 2, for receiving, analyzing and processing the image information acquired by the image acquisition component 2 to obtain result information; and a control host, which is electrically connected to the image acquisition component 2, the cleaning component 3 and the data acquisition unit, for controlling the working status of the image acquisition component 2, the cleaning component 3 and the data acquisition unit, and determining whether to control the top coal caving equipment to operate based on the result information from the data acquisition unit. Thus, this invention, by incorporating a coal gangue mixing degree identification device, can quickly and automatically identify the coal gangue mixing degree of the coal gangue discharged from the top coal caving equipment. This solves the problem in existing technologies where manual identification of coal gangue mixing degree is difficult and inefficient, reducing labor intensity, shortening the time required for identification, improving the working efficiency of the top coal caving equipment, and increasing the mining efficiency and utilization rate of coal resources.
