Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0022] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: a coal - mine tunneling support device, including a telescopic support rod 100; an output end of the telescopic support rod 100 is provided with an aluminum - alloy support plate 101. A plurality of drainage grooves 200 are opened on the aluminum - alloy support plate 101. A drainage structure is connected to the aluminum - alloy support plate 101. A slag - discharging groove 300 is provided on the drainage structure. A slag - discharging structure is installed in the slag - discharging groove 300. Two shaft seats 400 are installed on the aluminum - alloy support plate 101. An anti - blocking structure is installed on the two shaft seats 400. The aluminum - alloy support plate 101 can provide top protection during the coal - mine tunneling process. Water dripping from above the mine shaft can pass through the drainage grooves 200, and then be filtered by the drainage structure and discharged. By setting the slag - discharging structure, the filtered coal slag can be cleaned, and the anti - blocking structure can clean the coal slag in the drainage grooves 200 to prevent blockage.

[0023] Furthermore, the drainage structure includes a number of leakage holes 201. The leakage holes 201 are connected to a corresponding drainage groove 200. A water collecting box 202 is installed on the bottom side of the aluminum alloy support plate 101. The water collecting box 202 is connected to the leakage holes 201. A drain pipe 203 is installed on one side of the water collecting box 202. The drain pipe 203 is connected to the water collecting box 202. An arc-shaped filter plate 204 is installed on the inner wall of the water collecting box 202. The water dripping from above the mine can be drained by using the drainage groove 200, so that the water flows into the water collecting box 202 through the leakage holes 201. By setting the arc-shaped filter plate 204, the water can be filtered. After the water is filtered, it is discharged through the drain pipe 203, thus preventing the water from directly falling on the staff. By setting the arc-shaped filter plate 204, it can prevent the coal slag from blocking the drain pipe 203.

[0024] Furthermore, the slag discharging structure includes a bracket 301. The bracket 301 is installed on the inner wall of the slag discharging groove 300. The slag discharging groove 300 is opened on the inner wall of the water collecting box 202. The bracket 301 and the water collecting box 202 are rotatably installed with the same connecting shaft 302. A control motor 303 is installed on one side of the water collecting box 202. The output end of the control motor 303 is installed at one end of the connecting shaft 302. A spiral blade 304 is installed on the connecting shaft 302. The spiral blade 304 is in contact with the arc-shaped filter plate 204. The spiral blade 304 is located inside the water collecting box 202. When the control motor 303 is turned on, the output end of the control motor 303 can drive the connecting shaft 302 to rotate on the water collecting box 202 and the bracket 301. The continuously rotating connecting shaft 302 can drive the spiral blade 304 to rotate. Under the continuous rotation of the spiral blade 304, the coal slag accumulated on the arc-shaped filter plate 204 can be pushed out from the slag discharging groove 300.

[0025] Example 2: As Figures 1-4, in order to prevent the drainage groove 200 from being blocked by coal cinder during use, an anti-blocking structure is arranged on the shaft seat 400. The anti-blocking structure includes two rotating shafts 401, and the two rotating shafts 401 are respectively rotatably installed on the inner walls of the two shaft seats 400. One end of each of the two rotating shafts 401 is provided with a connecting rod 402, and the same magnetic rod 403 is installed on the two connecting rods 402. A magnetic push plate 404 is movably installed on the inner wall of the drainage groove 200. The magnetic push plate 404 corresponds to the magnetic rod 403. The magnetic push plate 404 is magnetically connected to the magnetic rod 403 through the aluminum alloy support plate 101. A double-headed motor 405 is installed on the aluminum alloy support plate 101, and the output end of the double-headed motor 405 is installed at one end of the rotating shaft 401. A limiting rotation hole 406 is opened on the inner wall of the shaft seat 400, and the rotating shaft 401 is rotatably installed in the limiting rotation hole 406. Two arc-shaped guide grooves 407 are opened on the magnetic push plate 404, and arc-shaped guide bars 408 are installed on both inner walls of the drainage groove 200. The two arc-shaped guide bars 408 are respectively movably installed in the two arc-shaped guide grooves 407. Two moving holes 409 are opened on the aluminum alloy support plate 101, and the two connecting rods 402 are respectively movably installed in the two moving holes 409. By controlling the positive and reverse rotation of the output end of the double-headed motor 405, it can drive the rotating shaft 401 to rotate. Thus, the rotating rotating shaft 401 can drive the connecting rod 402 to swing, so that the connecting rod 402 drives the magnetic rod 403 to perform a circular motion. The circularly moving magnetic rod 403 can drive the magnetic push plate 404 to move through the magnetic cooperation with the magnetic push plate 404. By controlling the reciprocating movement of the magnetic push plate 404 in the drainage groove 200, the moving magnetic push plate 404 can push the coal cinder falling into the drainage groove 200 to both sides. The other features are the same as those in Embodiment 1.

[0026] The working principle is as follows: When using the telescopic support rod 100 and the aluminum alloy support plate 101 for tunneling support in a coal mine, the coal slag falling from above the mine can be blocked and protected by the aluminum alloy support plate 101, and the dripping water can be drained by the drainage groove 200, so that the water flows into the water collection box 202 through the leakage holes 201. By setting the arc-shaped filter plate 204, the water can be filtered. After being filtered, the water is discharged through the drain pipe 203, thus preventing the water from directly falling on the staff. By setting the arc-shaped filter plate 204, it can prevent the coal slag from blocking the drain pipe 203. During the process, the control motor 303 can be turned on at the same time. The output end of the control motor 303 can drive the connecting shaft 302 to rotate on the water collection box 202 and the support 301. The continuously rotating connecting shaft 302 can drive the spiral blade 304 to rotate. Under the continuous rotation of the spiral blade 304, the coal slag accumulated on the arc-shaped filter plate 204 can be pushed out from the slag discharge groove 300, preventing the coal slag from accumulating on the arc-shaped filter plate 204 and causing it to be blocked. By controlling the positive and reverse rotation of the output end of the double-headed motor 405, it can drive the rotating shaft 401 to rotate in the limit rotation hole 406, so that the rotating shaft 401 can achieve the rotating effect. The rotating rotating shaft 401 can drive the connecting rod 402 to swing. During the swinging process of the connecting rod 402, it can move in the movable hole 409, so that the connecting rod 402 drives the magnetic rod 403 to move in a circular motion. The magnetic rod 403 moving in a circular motion can drive the magnetic push plate 404 to move through the magnetic cooperation with the magnetic push plate 404. By setting the drainage groove 200 to be made of aluminum alloy, it can prevent interference with the movement of the magnetic push plate 404, so that the moving magnetic push plate 404 slides on the two arc-shaped guide bars 408 through the arc-shaped guide grooves 407 on both sides respectively, thereby restricting the moving direction of the magnetic push plate 404, making the magnetic push plate 404 can only move in the drainage groove 200. By controlling the magnetic push plate 404 to reciprocate in the drainage groove 200, the moving magnetic push plate 404 can push the coal slag falling into the drainage groove 200 to both sides, so that the coal slag enters the water collection box 202 through the leakage holes 201 and is pushed out by the spiral blade 304, preventing the drainage groove 200 from being blocked by the coal slag.
