[0057] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0058] like Figures 1 to 10 As shown, the triangular coal cleaning device 100 for underground coal mining faces in this embodiment of the invention includes a lifting beam 1, a first driving component 2, a truss 3, a rotating frame 4, a second driving component 5, a push plate 6, and a third driving component 7.

[0059] The lifting beam 1 along the first direction (e.g.) Figure 1 Extending in the front-to-back direction, the lifting beam 1 is fixedly installed at the top of the coal mining face. The first driving component 2 is installed on the lifting beam 1. The truss 3 is connected to the first driving component 2, and the first driving component 2 drives the truss 3 to move in the first direction. The rotating frame 4 is rotatably installed on the truss 3 about the first rotation axis, which is along the second direction (e.g., in the front-to-back direction). Figure 1 The first rotation axis extends in the left-right direction, and the second direction is perpendicular to the first direction. The second driving member 5 is mounted on the truss 3 and is connected to the rotating frame 4 to drive the rotating frame 4 to rotate around the first rotation axis. The push plate 6 is rotatably mounted on the rotating frame 4 about the second rotation axis, which is along a third direction (e.g., the left-right direction). Figure 1 The third drive component 7 extends in the vertical direction (the direction above and below the second direction), and the third direction is perpendicular to the second direction. The third drive component 7 is mounted on the rotating frame 4 and is connected to the push plate 6 to drive the push plate 6 to rotate around the second rotation axis.

[0060] In the working environment of the underground coal mine working face triangular coal cleaning device 100 of this embodiment, the lifting beam 1 extends horizontally, and the axis of the first rotating shaft 51 extends horizontally. Figure 1 and Figure 2In the indicated directions, the lifting beam 1 extends in the front-to-back direction, the first rotation axis extends in the left-to-right direction, and the second rotation axis extends in the up-to-down direction. When not in use, the push plate 6 is in a horizontal or tilted state, which can be adjusted according to the needs of the on-site operation. During adjustment, the second drive component 5 is controlled to output power, causing the push plate 6 to rotate to a suitable angle.

[0061] In operation, the first drive unit 2 moves the truss 3 on the lifting beam 1, thereby moving the rotating frame 4 and the push plate 6. Once the push plate 6 is moved above the slag position, the second drive unit 5 rotates the rotating frame 4, causing the push plate 6 to rotate vertically, gradually bringing it to a vertical position. In other words, the second rotation axis gradually becomes vertical. As the push plate 6 rotates vertically, its lower end gradually descends and inserts into the slag. Then, the third drive unit 7 activates, causing the push plate 6 to rotate around the second rotation axis, i.e., rotating horizontally. This push plate 6 pushes the slag into the scraper conveyor. The pushing action of the push plate 6 is repeated. During this process, the position of the push plate 6 in the slag area is adjusted by controlling the first drive unit 2, thus pushing all the slag into the scraper conveyor and completing the slag removal process.

[0062] The triangular coal cleaning device for underground coal mining faces in this embodiment of the invention is based on the lifting beam 1. The push plate 6 can be moved by the first driving component 2. When the cleaning device 100 is not cleaning coal slag, the push plate 6 can be separated from the coal slag area, without occupying the working space, thereby avoiding affecting the normal operation of other coal mining processes. The push plate 6 can be adjusted in the vertical direction by the second driving component 5, so that when not cleaning coal slag, the push plate 6 can be rotated to a horizontal state, thereby not occupying the working space. When cleaning coal slag, the push plate 6 can be rotated to a vertical state to insert into the coal slag, and the push plate 6 can be driven by the third driving component 7 to push the coal slag, thereby achieving the cleaning of coal slag.

[0063] Therefore, the triangular coal cleaning device 100 for underground coal mining faces in this embodiment of the invention can drive the push plate 6 to move laterally, rotate vertically and horizontally, making it flexible in operation, improving the efficiency of coal slag cleaning, and occupying little space, easy to adjust, and with good applicability.

[0064] Specifically, the lifting beam 1 is a single-rail lifting beam 1.

[0065] In some embodiments, such as Figures 3 to 5 The first driving component 2 includes a moving frame 21, track wheels 22, transmission wheels 23, a conveyor belt 24, and a first drive motor 25.

[0066] A movable frame 21 is mounted on the lifting beam 1 and is movable relative to the lifting beam 1. The movable frame 21 is connected to the truss 3. Track wheels 22 are rotatably mounted on the movable frame 21 and abut against the movable frame 21. A transmission wheel 23 is rotatably mounted on the movable frame 21, and a conveyor belt 24 is mounted on the transmission wheel 23 and track wheels 22. A first drive motor 25 is mounted on the movable frame 21 and is connected to the transmission wheel 23. When the first drive motor 25 is activated, it drives the transmission wheel 23 to rotate, thereby driving the conveyor belt 24 to rotate. The conveyor belt 24 drives the track wheels 22 to rotate. The track wheels 22 move on the lifting beam 1 due to friction between themselves and the lifting beam 1, thus moving the movable frame 21 on the lifting beam 1, which in turn moves the rotating frame 4 and the push plate 6.

[0067] The first drive motor 25 and the track wheel 22 are driven by a conveyor belt 24, which makes the transmission of motion more stable and reliable.

[0068] Specifically, the first drive motor 25 is a first servo motor.

[0069] In some embodiments, such as Figure 4 and Figure 5 As shown, the first driving component 2 further includes a Geneva mechanism 26, which includes a driving dial 261 and a driven Geneva wheel 262. The driving dial 261 is connected to the output shaft of the first driving motor 25. The driven Geneva wheel 262 is coaxially arranged with the transmission wheel 23 and is connected to the driving dial 261. When the first driving motor 25 is on, it drives the driving dial 261 to rotate. The driving dial 261 and the driven Geneva wheel 262 cooperate to make the driven Geneva wheel 262 rotate intermittently, thereby driving the transmission wheel 23 to rotate intermittently. This drives the track wheel 22 to rotate intermittently through the first conveyor belt 24, thereby causing the moving frame 21 to move intermittently.

[0070] The grooved wheel mechanism 26 converts the continuous rotational motion output by the first drive motor 25 into intermittent rotational motion, dividing one rotation cycle (one revolution) of the active dial 261 into six equal parts. This continuous intermittent rotation process of the transmission wheel 23 (rotation, stopping, rotation, stopping) extends the movement time of the moving frame 21, thus providing sufficient working time for the pusher plate 6 to push coal. In other words, the process of the third drive member 7 driving the pusher plate 6 to push coal slag and the process of the first drive member 2 driving the pusher plate 6 to move laterally can occur simultaneously without affecting the coal pushing effect of the pusher plate 6. This improves the operating efficiency of the triangular coal cleaning device for underground coal mining faces in this embodiment of the invention.

[0071] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the truss 3 has mounting plates 31 at both ends in the second direction, and the mounting plates 31 extend downwards. The second driving component 5 includes a first rotating shaft 51, a second driving motor 52, a first worm 53, and a first worm wheel 54. The first rotating shaft 51 is rotatably mounted on the mounting plate 31 and is fixedly connected to the rotating frame 4. The first rotation axis is located on the axis of the first rotating shaft 51. The second driving motor 52 is mounted on one of the mounting plates 31. The first worm 53 is coaxially connected to the output shaft of the second driving motor 52. The first worm wheel 54 is mounted on the first rotating shaft 51 and meshes with the first worm 53. When the second driving motor 52 is turned on, the output shaft of the second driving motor 52 drives the first worm 53 to rotate synchronously. The first worm 53 meshes with the first worm 53, thereby driving the first rotating shaft 51 to rotate, which in turn drives the rotating frame 4 to rotate around the first rotation axis, thereby driving the push plate 6 to rotate in the vertical direction.

[0072] Specifically, the second drive motor 52 is the second servo motor.

[0073] The second drive motor 52 and the first rotating shaft 51 are driven by the first worm 53 and the first worm wheel 54. The first worm 53 and the first worm wheel 54 occupy a small space, which is convenient for them to be installed on the mounting plate 31. The meshing transmission process of the first worm 53 and the first worm wheel 54 is smooth and has little impact. At the same time, the rotating frame 4, the third drive component 7 and the push plate 6 have a certain weight, which forms a load on the first worm wheel 54, so that the first worm wheel 54 cannot drive the first worm 53 to rotate, thus forming a self-locking function. This can prevent the push plate 6 and the rotating frame 4 from rotating when the second drive motor 52 is off, ensuring the self-locking effect and safety of the second drive component 5, thereby ensuring the reliability of the triangular coal cleaning device for underground coal mining faces in this embodiment of the invention.

[0074] In some embodiments, the third driving component 7 includes a second rotating shaft 71, a third driving motor 72, a second worm 73, and a second worm wheel 74. The second rotating shaft 71 is rotatably mounted at one end (right end) of the rotating frame 4 along a third direction. The second rotating shaft 71 is fixedly connected to the push plate 6, and the second rotation axis is located on the axis of the second rotating shaft 71. The third driving motor 72 is mounted on the rotating frame 4. The second worm 73 is coaxially connected to the output shaft of the third driving motor 72. The second worm wheel 74 is mounted on the second rotating shaft 71 and meshes with the second worm 73. When the third driving motor 72 is in the on state, the output shaft of the third driving motor 72 drives the second worm 73 to rotate synchronously. The second worm 73 meshes with the second worm 73, thereby driving the second rotating shaft 71 to rotate, driving the push plate 6 to rotate, and thus pushing the slag.

[0075] Specifically, the third drive motor 72 is the third servo motor.

[0076] The third drive motor 72 and the second rotating shaft 71 are driven by the second worm 73 and the second worm wheel 74. The second worm 73 and the second worm wheel 74 occupy a small space, which is convenient for them to be arranged on the push plate 6. The meshing transmission process is smooth and the impact is small. At the same time, it has a self-locking function, which can prevent the push plate 6 from rotating when the third drive motor 72 is off, ensuring the self-locking effect and safety of the third drive component 7, thereby further ensuring the reliability of the triangular coal cleaning device for underground coal mining faces in this embodiment of the invention.

[0077] In some embodiments, the pusher plate 6 has a first end and a second end that are opposite each other in a third direction, such as Figure 6 As shown, the first end is the upper end of the push plate 6, and the second end is the lower end of the push plate 6. The third driving component 7 is located at the upper end of the push plate 6.

[0078] The push plate 6 has a guide rail 66 at its first end, and a sliding groove is provided on the guide rail 66. The sliding groove extends along the width direction of the push plate 6, such as... Figure 6 The left and right directions are shown.

[0079] In some embodiments, such as Figures 6 to 10 As shown, the triangular coal cleaning device for underground coal mining faces of the present invention further includes a vibration assembly 8. The vibration assembly 8 includes a connecting rod 81, a slider 82, an elastic actuating element 83, and an actuating plate 84. One end of the connecting rod 81 is rotatably connected to the other end (left end) of the rotating frame 4, and the slider 82 is rotatably connected to the other end of the connecting rod 81, with the slider 82 slidably disposed within a groove. The elastic actuating element 83 is disposed on the slider 82 and is located outside the groove. The actuating plate 84 is disposed at the first end of the push plate 6, and the elastic actuating element 83 is opposite to the convex toothed rack in the thickness direction of the push plate 6, with the elastic actuating element 83 abutting against the convex toothed rack.

[0080] like Figure 10 As shown, the included angle between the push plate 6 and the rotating frame 4 is α. When the third drive motor 72 drives the push plate 6 to rotate, α will change accordingly. Taking the process of α gradually increasing from 0° as an example, since the two ends of the connecting rod 81 are rotatably connected to the rotating frame 4 and the slider 82 respectively, and the slider 82 is slidably mounted on the push plate 6, during the rotation of the push plate 6, the slider 82 slides relative to the push plate 6, that is, the slider 82 slides in the groove. During the sliding of the slider 82, the elastic actuating element 83 on the slider 82 moves with the slider 82 relative to the actuating plate 84, that is, the elastic actuating element 83 moves along the length direction of the convex rack. Figure 8 and Figure 9As shown, the elastic actuating element 83 has a certain elasticity and can deform. As it moves along the length of the toothed rack, it gradually contacts the tooth valleys, peaks, and ridges, causing it to compress and deform, accumulating elastic force before releasing it to restore its deformation. This release impacts the actuating plate 84, which in turn impacts the push plate 6, causing it to vibrate. As the push plate 6 rotates, the intermittent impacts from the elastic actuating element 83 cause it to vibrate intermittently, resulting in the coal slag adhering to it falling off, ensuring the cleanliness of the push plate 6 and thus guaranteeing its effectiveness in cleaning the coal slag.

[0081] In some embodiments, the slider 82 has a through hole. The elastic actuating member 83 includes an actuating pin 831, an elastic member 832, and a limiting plate 833. The actuating pin 831 is movably disposed in the through hole of the slider 82. The actuating pin 831 has two limiting plates 833, one of which is adjacent to or abuts against the slider 82. One end of the elastic member 832 is connected to the slider 82, and the other end of the elastic member 832 abuts against the other of the two limiting plates 833. The actuating pin 831 abuts against the actuating plate 84. When the actuating pin 831 abuts against the groove of the tooth, the corresponding limiting plate 833 abuts against the slider 82. When the actuating pin 831 abuts against the peak of the tooth, the elastic member 832 deforms to its maximum, and the corresponding limiting plate 833 is spaced apart from the slider 82. When the elastic actuating member 83 moves along the length of the convex rack, the actuating pin 831 moves back and forth along the thickness of the push plate 6, and the elastic member 832 is compressed and reset, thereby creating a continuous intermittent vibration on the push plate 6.

[0082] In some embodiments, the elastic element 832 is a spring, which is sleeved on the actuating pin 831. The spring has a simple structure and is easy to install. The spring sleeved on the actuating pin 831 can guide the deformation of the spring, prevent the spring from tilting, and ensure the smoothness of the spring compression and extension. This ensures the vibration effect of the elastic actuating element 83 on the push plate 6, ensures the cleanliness of the push plate 6, and improves the reliability of the triangular coal cleaning device for underground coal mining faces in this embodiment of the invention.

[0083] In some embodiments, such as Figure 6As shown, the push plate 6 includes a first plate 61, a second plate 62, and a telescopic rod 63. The first plate 61 forms its first end (upper end) in the third direction, and has a mounting cavity with a guide rail 66 located at the upper end of the cavity. The second plate 62 forms its second end (lower end) in the third direction, and is slidably disposed within the mounting cavity. The telescopic rod 63 is located within the mounting cavity, with one end on the first plate 61 and the other end connected to the other end of the second plate 62 in the third direction. When the telescopic rod 63 extends, it causes the second plate 62 to gradually extend out of the mounting cavity, causing the push plate 6 to gradually increase in its length direction. When the telescopic rod 63 shortens, it causes the second plate 62 to gradually move into the mounting cavity, causing the push plate 6 to gradually decrease in its length direction.

[0084] Therefore, the length of the push plate 6 is adjustable, which allows the depth to which the push plate 6 can be inserted into the coal slag to be adjusted, enabling the push plate 6 to adapt to coal slag at different depths, thereby improving the effect and efficiency of the push plate 6 in cleaning coal slag and enhancing the reliability of the triangular coal cleaning device for underground coal mining faces in this embodiment of the invention.

[0085] In some embodiments, the push plate 6 further includes a guide post 64 and a guide plate 65. The guide plate 65 is disposed within the mounting cavity and has a guide hole. The guide post 64 is connected to the other end of the second plate 62 and is slidably disposed within the guide hole. The cooperation of the guide post 64 and the guide plate 65 guides the movement of the second plate 62, ensuring the smooth movement of the second plate 62 relative to the first plate 61, thereby improving the reliability of the triangular coal cleaning device for underground coal mining faces in this embodiment of the invention.
