[0014] A method for using a mining inorganic material grouting reinforcement device, using the above-mentioned mining inorganic material grouting reinforcement device, comprising the following steps: Step 1: Pour the slurry into the grouting barrel through the slurry inlet, and at the same time, the servo motor drives the rotating rod to rotate counterclockwise, the rotating rod rotates counterclockwise to drive the hollow rod to rotate, the hollow rod rotates to drive the extrusion rod to rotate, the extrusion rod rotates to contact the stabilizing block and extrude the stabilizing block; Step 2: The extrusion rod moves upwards due to the reaction force of the extrusion stabilizing block, and the upward movement of the extrusion rod drives the hollow rod to move upwards, and the upward movement of the hollow rod squeezes the No. 1 spring, and the No. 1 spring is squeezed by the hollow rod to produce deformation and store force; Step 3: At the same time, the hollow rod moves upward to drive the stabilizing ring and the L-shaped rod to move upward. After the extrusion rod continues to rotate and disengages from the stabilizing block, the hollow rod moves downward to reset under the elastic force of the No. 1 spring. The downward movement of the hollow rod to reset drives the stabilizing ring and the L-shaped rod to move downward to reset. Step 4: The L-shaped rod moves back and forth to stir the slurry at the bottom of the grouting barrel. When grouting reinforcement is required for the mine, the slurry pump is started to extract the slurry inside the grouting barrel through the slurry pipe and grouting operation is carried out through the slurry outlet pipe.

[0015] The present invention provides a mining inorganic material grouting reinforcement device, which has the following beneficial effects: (1) The invention uses an L-shaped rod to push the connection between the grouting pipe and the grouting barrel to prevent oversized solid particles from blocking the slurry from entering the grouting pipe and affecting the grouting efficiency. By pushing oversized solid particles, the channel at the connection can be ensured to be unobstructed, reducing the blockage and obstruction of solid particles, thereby ensuring the continuous flow of slurry and improving the uniformity and efficiency of grouting. The vibration of the convex block drives the hollow rod and the stabilizing ring to vibrate, and the vibration of the stabilizing ring drives the L-shaped rod to resonate together. The resonant vibration allows the L-shaped rod to move more effectively in the slurry, ensuring that the slurry is evenly stirred in different depths and areas. The L-shaped rod is moved back and forth to stir the slurry at the bottom of the grouting barrel. Stirring the slurry can reduce the viscosity of the slurry and make it more fluid, ensuring that the slurry can be smoothly drawn into the grouting pipe, thereby improving the grouting efficiency.

[0016] (2) In the present invention, the pressing frame is driven downward by the downward movement of the connecting rod. The pressing frame stirs the slurry inside the grouting tube by the reciprocating movement. Stirring the slurry can prevent the material from settling at the bottom or top of the grouting tube, ensuring that the slurry is evenly mixed throughout the grouting tube, helping to ensure consistent slurry performance and avoid problems with uneven local concentration of the slurry. At the same time, the counterclockwise rotation of the rotating rod drives the hollow tube to rotate, and the rotation of the hollow tube drives the connecting rod to rotate. The rotation of the connecting rod drives the scraper rod to rotate to scrape the inner wall of the grouting tube. Scraping helps prevent the slurry on the inner wall from settling or condensing, thereby keeping the inner wall clean and improving construction efficiency.

[0017] (3) In the present invention, part of the retarder inside the support frame is squeezed by the support plate into the liquid inlet pipe. The retarder inside the liquid inlet pipe squeezes the rubber block. The rubber block is squeezed by the retarder inside the liquid inlet pipe and deforms. The deformation of the rubber block releases the seal of the liquid inlet pipe. After the seal of the liquid inlet pipe is released, part of the retarder inside the support frame enters the grouting barrel through the liquid inlet pipe. The quantitative addition of retarder can accurately control the setting time of the slurry, so that the construction personnel have enough time to operate and adjust, ensuring that the slurry can be smoothly injected and cover the entire construction area. In addition, the appropriate amount of retarder added can help the slurry reach the optimal strength within the set time, thereby enhancing the stability and durability of the structure.

7. The inorganic material grouting reinforcement device for mining according to claim 6 is characterized in that: The feeding device comprises an adding frame (161), an adding rod (162), a supporting frame (163), a supporting plate (164), a supporting rod (165), a liquid inlet hole (166) and a liquid inlet pipe (167); the adding frame (161) is fixedly mounted on the top of the grouting barrel (1); the adding rod (162) slides through the bottom of the inner wall of the adding frame (161); the supporting frame (163) is fixedly mounted on the bottom of the inner wall of the adding frame (161); the supporting plate (164) is slideably mounted on the inner wall of the supporting frame (163); the supporting rod (165) is fixedly mounted on a side of the supporting plate (164) close to the servo motor (6); the liquid inlet hole (166) is provided on the front side of the supporting frame (163); the liquid inlet pipe (167) is fixedly mounted on the bottom of the supporting frame (163); and the adding rod (162) penetrates the top of the grouting barrel (1).

8. The inorganic material grouting reinforcement device for mining according to claim 7 is characterized in that: A retarder is arranged inside the adding frame (161), a No. 3 spring is arranged between the adding rod (162) and the grouting cylinder (1), a rubber block is arranged inside the liquid inlet pipe (167), and a No. 4 spring is arranged between the supporting frame (163) and the supporting plate (164).

9. A method for using a mining inorganic material grouting reinforcement device, using the mining inorganic material grouting reinforcement device according to claim 8, characterized in that: The following steps are involved: Step 1: Slurry is injected into the grouting barrel (1) through the slurry inlet (2), and at the same time, the servo motor (6) operates to drive the rotating rod (7) to rotate counterclockwise, and the rotating rod (7) rotates counterclockwise to drive the hollow rod (8) to rotate, and the rotation of the hollow rod (8) drives the extrusion rod (11) to rotate, and the extrusion rod (11) rotates to contact the stabilizing block (12) and extrude the stabilizing block (12); Step 2: The extrusion rod (11) moves upwards due to the reaction force of the extrusion stabilizing block (12), and the upward movement of the extrusion rod (11) drives the hollow rod (8) to move upwards. The upward movement of the hollow rod (8) compresses the No. 1 spring, and the No. 1 spring is deformed and stores force due to the compression of the hollow rod (8); Step 3: At the same time, the hollow rod (8) moves upward, driving the stabilizing ring (9) and the L-shaped rod (10) to move upward. After the extrusion rod (11) continues to rotate and is out of contact with the stabilizing block (12), the hollow rod (8) moves downward and resets under the elastic force of the first spring. The downward movement of the hollow rod (8) drives the stabilizing ring (9) and the L-shaped rod (10) to move downward and reset. Step 4: The L-shaped rod (10) stirs the slurry at the bottom of the grouting tube (1) by reciprocating movement. When grouting reinforcement is required for the mine, the grouting pump (3) is started to extract the slurry inside the grouting tube (1) through the grouting pipe (4) and perform grouting operations through the grouting pipe (5).
