Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0039] Please refer to Figures 1-8, an embodiment of the present invention is: a grading grouting reinforcement device for mine inorganic materials, including a trolley 1. A reverse U-shaped frame 2 is fixedly installed on the top surface of the trolley 1. A circular opening is formed in the middle of the top surface of the trolley 1.

The bottom surface of the telescopic ends of the two electric telescopic rods 3 is fixed with a circular cover 4. The outer wall of the circular cover 4 is slidably connected to the inner wall of the circular opening of the trolley 1. A double-hole block 5 penetrates and is fixedly installed on the top surface of the circular cover 4. Two material pipes 6 penetrate and are fixedly installed on the top surface of the double-hole block 5. A number of connecting pieces 7 are respectively fixed on the right sides of the outer walls of the two material pipes 6. The bottom surfaces of the number of connecting pieces 7 are fixedly connected to the top surface of the trolley 1. A circular shell 8 is fixed in the middle of the top surface of the circular cover 4. The circular shell 8 is located between the two electric telescopic rods 3. A motor 9 is fixedly installed at the top of the inner wall of the circular shell 8. A thick rod 10 penetrates and is rotatably installed in the middle of the top surface of the circular cover 4. The top surface of the thick rod 10 is fixedly connected to the bottom surface of the rotating shaft of the motor 9. A hanging ring 11 is fixed at the top end inside the circular cover 4. The inner wall of the hanging ring 11 is rotatably connected to the outer wall of the top of the thick rod 10. Three inclined scraping plates 12 are fixed to the bottom of the outer wall of the thick rod 10. One end of each of the two material pipes 6 away from the double-hole block 5 is respectively provided with a connection port. A number of strip-shaped openings are formed in the outer wall of the circular shell 8. Circular grooves are formed on the top surfaces of the three inclined scraping plates 12. The material pipe 6 transports the fine slurry into the foundation pit. The rotating shaft of the motor 9 drives the thick rod 10 to rotate forward. The thick rod 10 rotates forward in the hanging ring 11, enabling the thick rod 10 to rotate stably. The thick rod 10 drives the inclined scraping plates 12 to rotate forward. The inclined scraping plates 12 scrape the fine slurry flat, allowing the fine slurry to penetrate into the cracks at the mine entrance. The material pipe 6 transports the thick slurry into the foundation pit. The electric telescopic rod 3 slowly drives the circular cover 4 to move upward. The circular cover 4 slowly drives the thick rod 10 to move upward. The thick rod 10 drives the inclined scraping plates 12 to move upward. The inclined scraping plates 12 slowly rotate upward. The inclined scraping plates 12 level the thick slurry in the foundation pit, enabling the fine slurry to penetrate into the cracks for bonding. The thick slurry reinforces the surface of the mine entrance in the foundation pit, allowing the fine slurry and the thick slurry to reinforce the mine entrance in a graded manner, avoiding the situation that it is difficult to reinforce the inside of the gaps at the mine entrance during the reinforcement of the mine entrance by the grouting reinforcement device, resulting in poor reinforcement effect. A push frame 15 is fixedly installed on the right side of the top surface of the trolley 1. A lower strip plate 16 penetrates and is fixed to the bottom surface of the push frame 15. The lower strip plate 16 is located on the right side of the trolley 1. A chamfered plate 17 is fixed to the bottom surface of the lower strip plate 16. The chamfered plate 17 levels the surface of the thick slurry in the foundation pit, making the thick slurry on the surface of the mine entrance more dense;

[0040] A feeding device 13 is arranged on the inner wall of the circular grooves of the three inclined scraping plates 12. The feeding device 13 scrapes off the mine inorganic materials at the discharge ports of the two material pipes 6. An anti-adhesion device 14 is arranged on the inner wall of the feeding device 13. The anti-adhesion device 14 is used to scrape off the mine inorganic materials attached to the inner wall of the circular cover 4.

[0041] During the reinforcement of the mine entrance, if the slurry is too thick, it is difficult to enter the cracks in the mine entrance for bonding; if the slurry is too thin, it is difficult to reinforce the surface of the mine entrance. When using the equipment, the operator digs a foundation pit at the edge of the mine entrance. The operator uses the push frame 15 to push the trolley 1 to the mine entrance, aligns the round cover 4 with the foundation pit, and the connecting piece 7 fixes the two material pipes 6. The operator pours thick slurry into the connection port of one material pipe 6 and thin slurry into the connection port of the other material pipe 6. The trolley 1 supports the inverted U-shaped frame 2. The operator starts the electric telescopic rod 3 on the inverted U-shaped frame 2, and the telescopic end of the electric telescopic rod 3 starts to move downward. The telescopic end of the electric telescopic rod 3 drives the round cover 4 to move downward, the round cover 4 drives the double-hole block 5 to move downward, and the double-hole block 5 drives the material pipe 6 to move downward. The round cover 4 contacts the bottom of the foundation pit, and the material pipe 6 transports the thin slurry into the foundation pit. At the same time, the round cover 4 supports the round shell 8. The operator starts the motor 9 in the round shell 8, and the rotating shaft of the motor 9 starts to rotate forward. The rotating shaft of the motor 9 drives the thick rod 10 to rotate forward. The thick rod 10 rotates forward in the round cover 4. The round cover 4 supports the hanging ring 11, and the thick rod 10 rotates forward in the hanging ring 11 to enable the thick rod 10 to rotate stably. The thick rod 10 drives the inclined scraper 12 to rotate forward, and the inclined scraper 12 levels the thin slurry to allow the thin slurry to penetrate into the cracks in the mine entrance. When the cracks are filled with the thin slurry, the material pipe 6 transports the thick slurry into the foundation pit. The operator starts the electric telescopic rod 3, and the telescopic end of the electric telescopic rod 3 starts to move slowly upward. The electric telescopic rod 3 slowly drives the round cover 4 to move upward, the round cover 4 slowly drives the thick rod 10 to move upward, the thick rod 10 drives the inclined scraper 12 to move upward, and the inclined scraper 12 slowly rotates upward. The inclined scraper 12 levels the thick slurry in the foundation pit, so that the thin slurry penetrates into the cracks for bonding, and the thick slurry reinforces the surface of the mine entrance in the foundation pit, allowing the thin slurry and the thick slurry to reinforce the mine entrance in stages, preventing the inside of the gaps in the mine entrance from being difficult to reinforce when the equipment is in use, and thus avoiding the problem of poor reinforcement effect caused by the difficulty in reinforcing the inside of the gaps in the mine entrance when the grouting reinforcement device reinforces the mine entrance. When the reinforcement is completed, the operator pushes the push frame 15 to move leftward. The push frame 15 drives the lower strip 16 to move leftward, and the lower strip 16 drives the chamfered plate 17 to move leftward. The chamfered plate 17 levels the surface of the thick slurry in the foundation pit to make the thick slurry on the surface of the mine entrance more dense.

[0042] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, three vertical rods 131 are respectively fixed on the inner walls of the circular grooves of the three inclined scraping plates 12. A circular ring 132 is fixed on the top surfaces of the three vertical rods 131. Three connecting blocks 133 are fixed on the top surface of the circular ring 132. Three L-shaped rods 134 are respectively fixed on the inner walls of the three connecting blocks 133. Three rectangular plates 135 are respectively embedded at the ends of the three L-shaped rods 134 far away from the three connecting blocks 133. The bottom surfaces of the discharge ports of the two rectangular plates 135 are on the movement trajectories of the outer walls of the three rectangular plates 135. During the rotation of the rectangular plates 135, the rectangular plates 135 scrape off the slurry accumulated at the discharge port of the material pipe 6, avoiding a poor discharge effect of the equipment caused by a large amount of slurry accumulated at the discharge port of the material pipe 6 when the grouting reinforcement device reinforces the mine entrance.

[0043] At the ends of the three L-shaped rods 134 far away from the three rectangular plates 135, a ring concave plate 136 is fixed. Three notches are formed on the outer wall of the ring concave plate 136. A number of triangular blocks 137 are fixed on the top surface of the ring concave plate 136. A straight rod 138 is fixed at the top end of the round cover 4. The straight rod 138 is located on the right side of the hanging ring 11. A spring piece 139 is embedded at the bottom surface of the straight rod 138. The outer wall of the spring piece 139 is on the movement trajectories of the number of triangular blocks 137. During the rotation of the triangular blocks 137, the triangular blocks 137 hit the spring piece 139, the spring piece 139 deforms, the triangular blocks 137 generate vibrations, and the triangular blocks 137 transmit the vibrations to the rectangular plates 135. The rectangular plates 135 vibrate to scrape off the slurry on the discharge port of the material pipe 6, avoiding the blockage of the discharge port of the material pipe 6 caused by the adhesion of the slurry on the discharge port of the material pipe 6 when the grouting reinforcement device reinforces the mine entrance.

Three double arc plates 143 are respectively fixed at the ends of the three straight frames 141 far away from the ring concave plate 136. Three vertical plates 144 are respectively embedded on the sides of the three double arc plates 143 far away from the three straight frames 141. The outer walls of the three vertical plates 144 are in sliding contact with the inner wall of the round cover 4. During the rotation of the vertical plates 144, the vertical plates 144 scrape off the slurry sputtered on the wall surface of the round cover 4, avoiding the waste of slurry caused by a large amount of slurry accumulated on the wall surface of the round cover 4 when the grouting reinforcement device reinforces the mine entrance.

[0045] On the outer walls of the three straight frames 141, three U-shaped frames 145 are respectively fixed. On the outer walls of the three U-shaped frames 145, three short rods 146 are respectively fixed. At the ends of the three short rods 146 away from the three U-shaped frames 145, three inclined plate pieces 147 are respectively fixed. The three inclined plate pieces 147 are located below the discharge ports of the two material pipes 6. The slurry discharged from the material pipes 6 contacts the inclined plate pieces 147. During the rotation of the inclined plate pieces 147, the inclined plate pieces 147 evenly spread the slurry in the foundation pit, avoiding the poor reinforcement effect of the equipment caused by uneven material discharge of the equipment when the grouting reinforcement device reinforces the mine entrance.

[0047] S1. Dig a circle of foundation pit at the edge of the mine entrance, push the trolley 1 to the mine entrance, align the round cover 4 with the foundation pit, and connect thick slurry and thin slurry to the connection ports of the two material pipes 6 respectively.

During the rotation of the rectangular plate 135, the rectangular plate 135 scrapes off the slurry accumulated at the discharge port of the material pipe 6, preventing a large amount of slurry from accumulating at the discharge port of the material pipe 6 when the equipment is in use, thereby avoiding the problem of poor discharging effect of the equipment caused by a large amount of slurry accumulating at the discharge port of the material pipe 6 when the grouting reinforcement device reinforces the mine entrance.

[0056] While the connecting block 133 drives the L-shaped rod 134 to rotate forward, the L-shaped rod 134 drives the ring concave plate 136 to rotate forward, the ring concave plate 136 drives the triangular block 137 to rotate forward. At the same time, the round cover 4 supports the straight rod 138, the straight rod 138 supports the spring piece 139. During the rotation of the triangular block 137, the triangular block 137 hits the spring piece 139, the spring piece 139 deforms, the triangular block 137 generates vibration, the triangular block 137 transmits the vibration to the ring concave plate 136, the ring concave plate 136 transmits the vibration to the L-shaped rod 134, and the L-shaped rod 134 transmits the vibration to the rectangular plate 135. The rectangular plate 135 vibrates to scrape off the slurry on the discharge port of the material pipe 6, preventing the slurry from adhering to the discharge port of the material pipe 6 when the equipment is in use, thereby avoiding the problem of blockage of the discharge port of the material pipe 6 caused by the slurry adhering to the discharge port of the material pipe 6 when the grouting reinforcement device reinforces the mine entrance.

During the rotation of the vertical plate 144, the vertical plate 144 shovels off the slurry sputtered on the wall surface of the round cover 4, preventing a large amount of slurry from accumulating on the wall surface of the round cover 4 when the equipment is in use, thereby avoiding the problem of slurry waste caused by a large amount of slurry accumulating on the wall surface of the round cover 4 when the grouting reinforcement device reinforces the mine entrance.

[0058] While the ring concave plate 136 drives the straight frame 141 to rotate forward, the straight frame 141 drives the return frame 145 to rotate forward, the return frame 145 drives the short rod 146 to rotate forward, and the short rod 146 drives the inclined plate 147 to rotate forward. During the feeding process of the material pipe 6, the slurry discharged from the material pipe 6 contacts the inclined plate 147. During the rotation of the inclined plate 147, the inclined plate 147 evenly spreads the slurry in the foundation pit, preventing the discharging of the equipment from being uneven when the equipment is in use, thereby avoiding the problem of poor reinforcement effect of the equipment caused by uneven discharging of the equipment when the grouting reinforcement device reinforces the mine entrance.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
