[0026] Example 1

[0027] Please see Figures 1-7 This utility model relates to a coal gangue underground filling device and filling mechanism, including a conveying shell 1, with a gangue pipe 2 connected to the top of the conveying shell 1, and a belt conveyor 3 installed at the bottom of the conveying shell 1; an adjustment component is provided on one side of the conveying shell 1, the adjustment component including a support shell 4, the support shell 4 being installed on one side of the conveying shell 1, an adjustment shell 5 being fixedly connected between the support shell 4 and the conveying shell 1, a hydraulic rod 6 being movably connected inside the support shell 4, and a baffle 7 being movably connected to the output end of the hydraulic rod 6; a detection component is provided inside the conveying shell 1, the detection component including a pressure sensor 8, the pressure sensor 8 being installed inside the support shell 4 and the conveying shell 1 respectively, and a guide plate 9 being fixedly connected to the top of the pressure sensor 8.

Pressure sensor 8 is electrically connected to external controller to trigger the action of hydraulic rod 6.

[0029] Example 2

[0030] Please see Figures 1-7 Based on Embodiment 1, a buffer assembly is provided inside the conveying shell 1. The buffer assembly includes a movable shaft 10, which is movably connected to the inside of the conveying shell 1. A buffer plate 11 is fixedly connected to the surface of the movable shaft 10. A damper 12 is movably connected to the bottom of the buffer plate 11. A spring 13 is sleeved on the surface of the damper 12. The spring 13 is used to provide elastic restoring force to assist the buffer plate 11 in absorbing impact and restoring its position. A bearing seat 14 is movably connected to the bottom of the damper 12. One side of the bearing seat 14 is fixedly connected to the inner wall of the conveying shell 1. The top of the baffle 7... A support shaft 15 is fixedly connected to the main body. The surface of the support shaft 15 is movably connected to the inner wall of the adjusting shell 5 through a bearing. The baffle 7 can rotate counterclockwise from 0° to 160° around the support shaft 15 to control the opening and closing of the adjusting shell 5. A drive motor 16 is fixedly connected to one side of the guide plate 9. A conveying auger 17 is fixedly connected to the output end of the drive motor 16. A discharge port 18 is opened on the opposite side of the conveying shell 1 and the support shell 4. A cover 19 is installed on the surface of the discharge port 18. A guide shell 20 is fixedly connected to the bottom of the conveying shell 1. An opening is opened at the bottom of the guide shell 20.

[0031] Specifically: the buffer plate 11 is installed inside the conveying shell 1 via the movable shaft 10. The buffer plate 11 is located at the bottom of the gangue pipe 2. After the gangue falls through the gangue pipe 2, the impact force of the gangue can be buffered by the buffer plate 11. The damper 12 is installed at the bottom of the buffer plate 11 and can absorb the impact force of the gangue. The drive motor 16 can drive the conveying auger 17 to rotate. When the gangue falls into the top of the guide plate 9, it can be conveyed. The guide shell 20 can guide the gangue to the belt conveyor 3. The discharge port 18 and the cover 19 are used to guide the gangue discharged from the support shell 4 and the conveying shell 1 into the guide shell 20 to complete the centralized conveying.

[0032] Example 3

[0033] Please see Figures 1-7Based on Embodiments 1 and 2, a coal gangue underground filling mechanism is provided. A base 21 is installed at the bottom of a belt conveyor 3. A drive box 22 is installed at the rear of the base 21. A rotating shell 23 is provided at the top of the drive box 22. A discharge shell 24 is connected to the rear of the rotating shell 23. A rotating motor 25 is installed inside the drive box 22. Overload protection is achieved through belt drive to avoid direct damage to the rotating motor 25. A first belt pulley 26 is fixedly connected to the output end of the rotating motor 25. A drive shaft 27 is fixedly connected to the bottom of the rotating shell 23. The bottom of the drive shaft 27 extends through the inside of the drive box 22 and is fixedly connected to a second belt pulley 28. The first belt pulley 26 and the second belt pulley 28 are connected by belt drive. The surface of the drive shaft 27 is movably connected to the inner wall of the drive box 22 through bearings.

[0034] Specifically: the rotating shell 23 and the discharge shell 24 can guide and transport the backfilled gangue, which is discharged into the landfill pit through the discharge shell 24. The first belt pulley 26 and the second belt pulley 28 are connected by belt drive, which can transmit power to the rotating motor 25. The rotating motor 25 is protected by the soft drive of the belt. When the rotating shell 23 drives the discharge shell 24 to rotate, the discharge range of gangue can be adjusted.

[0035] The working principle of this utility model is as follows: when the gangue is transported from the ground to the ground through the gangue pipe 2, the buffer plate 11 and the damper 12 are used to buffer the falling gangue and reduce the impact force. When the gangue falls onto the guide plate 9, the drive motor 16 can be started by the external controller. The drive motor 16 drives the conveying auger 17 to rotate and transport the gangue into the guide shell 20.

[0036] Then, the belt conveyor 3 is started to transport the falling gangue to the rotating shell 23, and then the gangue is discharged into the landfill pit through the discharge shell 24 to complete the filling construction. During the landfilling process, the rotating motor 25 can be started. The rotating motor 25 drives the first belt pulley 26 to rotate. The first belt pulley 26 drives the second belt pulley 28 and the drive shaft 27 to rotate through the belt. The drive shaft 27, together with the rotating shell 23, drives the discharge shell 24 to rotate, thereby adjusting the discharge range of gangue. This can increase the uniformity of gangue landfilling and improve construction efficiency.

[0037] When the pressure sensor 8 detects that the weight of the gangue on the guide plate 9 exceeds the threshold, the hydraulic rod 6 is activated, driving the baffle 7 to rotate to the open state, opening the regulating shell 5. The gangue falling from the gangue pipe 2 will be guided into the regulating shell 5 through the buffer plate 11 and enter the support shell 4, completing the transfer of gangue and diverting the gangue transportation. This effectively reduces the risk of gangue clogging the gangue pipe 2. At the same time, when gangue accumulates inside both the conveying shell 1 and the support shell 4, the pressure sensor 8 can transmit a signal to the external control terminal to remind the ground personnel to stop the transportation of gangue and promptly repair the blocked location.

[0038] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
