[0020] like Figure 1-5 As shown, this utility model provides a coal-blocking structure for a coal mining machine, including a base 1. A top plate 13 is installed at the top of the base 1 to support the top of the mine shaft. A first fixing block 2 and a second fixing block 21 are fixedly installed on both sides of the base 1, respectively. The first fixing block 2 and the second fixing block 21 are connected to position two devices. A connecting groove 22 is opened in both the first fixing block 2 and the second fixing block 21. A fixing frame 23 is fixedly installed on the side of the base 1 near the first fixing block 2. A plug rod 24 is movably inserted into the fixing frame 23. The plug rod 24 can connect the first fixing block 2 and the second fixing block 21. The inner part of the 23 is equipped with a rotating shaft 25, which rotates and drives the rotating plate 26 to rotate. The rotating plate 26 is fixed on the outer side of the rotating shaft 25. The rotation of the rotating plate 26 drives the fixed rod 27 to swing. The fixed rod 27 is fixed on the outer side of the rotating plate 26. The swing of the fixed rod 27 causes the operating plate 28 to move up and down through the square groove 29. The top of the insertion rod 24 is fixed with the operating plate 28. The operating plate 28 has a square groove 29. The insertion rod 24 is movably inserted into the square groove 29. The top of the base 1 is equipped with a first connecting frame 11, and the top of the first connecting frame 11 is equipped with a second connecting frame 12. The second connecting frame 12 is rotatably connected to the top plate 13.

[0021] An extension plate 4 is movably inserted into the top plate 13. A symmetrically distributed sliding groove 41 is opened at the bottom of the top plate 13. A sliding frame 42 is movably inserted into the sliding groove 41. The sliding frame 42 is fixedly connected to the extension plate 4. A second hydraulic cylinder 43 is fixedly installed at the bottom of the top plate 13. The output end of the second hydraulic cylinder 43 is fixedly connected to the sliding frame 42.

[0022] By adopting the above technical solution, the support range of the top plate 13 can be expanded, thereby allowing the support range to be adjusted according to needs.

[0023] A traction assembly 15 is fixedly installed on the outer side of the base 1.

[0024] By adopting the above technical solution, the traction component 15 is used to traction the device.

[0025] The extension plate 4 has a side plate 44 that rotates on its outer side.

[0026] By adopting the above technical solution, the side plate 44 can support the side of the mine tunnel.

[0027] A third hydraulic cylinder 45 is rotatably mounted on the outer side of the sliding frame 42, and the output end of the third hydraulic cylinder 45 is rotatably connected to the side plate 44.

[0028] By adopting the above technical solution, the No. 3 hydraulic cylinder 45 can drive the side plate 44 to rotate.

[0029] The top of the base 1 is equipped with a symmetrically distributed No. 1 hydraulic cylinder 14, and the output end of the No. 1 hydraulic cylinder 14 is rotatably connected to the top plate 13.

[0030] By adopting the above technical solution, the No. 1 hydraulic cylinder 14 can drive the top plate 13 to adjust up and down.

[0031] A worm gear 3 is rotatably mounted inside the fixed frame 23, and a worm wheel 31 is fixedly mounted on the outside of the rotating shaft 25. The worm gear 3 and the worm wheel 31 mesh with each other.

[0032] By adopting the above technical solution, the worm 3 rotates, driving the worm wheel 31 to rotate.

[0033] A motor 32 is fixedly mounted on the top of the fixed frame 23. The end of the output shaft of the motor 32 is inserted through the fixed frame 23 and fixedly connected to the worm gear 3.

[0034] By adopting the above technical solution, the end of the output shaft of the motor 32 rotates, driving the worm gear 3 to rotate, thereby providing power output.

[0035] Working principle: First, the device is installed sequentially inside the mine, with the second fixing block 21 positioned below the first fixing block 2. Then, the motor 32 is started, causing it to operate. The output shaft of the motor 32 rotates, driving the worm gear 3 to rotate. The worm gear 3 rotates, driving the meshing worm wheel 31 to rotate. The worm wheel 31 rotates, driving the rotating shaft 25 to rotate. The rotating shaft 25 rotates, driving the rotating plate 26 to rotate. The rotating plate 26 rotates, driving the fixing rod 27 to rotate. The fixing rod 27 rotates, causing the operating plate 28 to move downwards with the assistance of the square slot 29. The downward movement of the operating plate 28 moves the insertion rod 24, which is then inserted into the first fixing block 2. Within the second fixing block 21, the connection and limiting between the devices are completed, and the coal retaining structure is reliably connected, which can significantly enhance its overall stability and reduce loosening or displacement caused by vibration, impact and other factors, thereby ensuring the safety and support effect of the coal mine roadway. When it is necessary to adjust the support range of the roof 13, the second hydraulic cylinder 43 is activated, so that the second hydraulic cylinder 43 starts to work. The output end of the second hydraulic cylinder 43 drives the sliding frame 42 to slide in the sliding groove 41. The movement of the sliding frame 42 drives the extension plate 4 to move. By extending the extension plate 4, the support range of the roof 13 can be expanded, so that the support range can be adjusted according to the needs.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
