DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Example 1: Reference Figure 1-3 The coal mine tunnel grouting and water blocking equipment comprises a first storage shell 1, a shell cover 2 is threadedly sleeved on the upper end of the first storage shell 1, a power part 3 is fixedly installed at the bottom of the first storage shell 1, the power part 3 is a motor, a cleaning rod 5 is fixedly installed on one side of the control output end of the power part 3, a brush 6 is fixedly installed on the surface of the cleaning rod 5, and the brush 6 fits the inner wall of the first storage shell 1. Starting the power part 3 can drive the cleaning rod 5 to rotate, and the rotation of the cleaning rod 5 can clean the inner wall surface of the first storage shell 1 through the brush 6. By cleaning, the slurry can be prevented from adhering to the inner wall surface of the first storage shell 1, and the slurry adhering to the inner wall of the first storage shell 1 can be prevented from drying and solidifying, which affects the smoothness and cleanliness of the inner wall of the first storage shell 1. After the adhered slurry accumulates for a long time, the thickness of the slurry adhering to the inner wall of the first storage shell 1 is relatively thick, which will reduce the storage space inside the first storage shell 1.
[0020] The top of the shell cover 2 is fixedly mounted with a nozzle 16, which is tilted and arranged in a circular array along the central axis of the shell cover 2. Figure 1 As shown, the nozzle 16 is connected to an external water supply device, and the nozzle 16 is tilted to flush the side wall of the first storage shell 1. During the flushing process of the nozzle 16, the cleaning rod 5 can be driven to rotate by the power member 3, and the bristles 6 can brush the inner wall of the first storage shell 1 with the cooperation of the water sprayed by the nozzle 16, and the slurry remaining inside the bristles 6 can also be washed away. The upper end of the cleaning rod 5 extends to the inside of the shell cover 2, and can brush the inner wall surface of the shell cover 2 to avoid blockage inside the shell cover 2.
[0021] A stirring screw 4 is fixedly mounted at the end of the power member 3 , and the power member 3 can drive the stirring screw 4 to rotate. The rotation of the stirring screw 4 can stir the slurry inside the first storage shell 1 , and can prevent the slurry from settling or solidifying after standing for a long time.
[0022] A first connecting pipe 7 is fixedly connected to one side of the bottom of the first storage shell 1, and a grouting pipe 8 is fixedly connected to the end of the first connecting pipe 7. The grouting pipe 8 is used for grouting operation. A flow regulating mechanism is fixedly installed inside the grouting pipe 8. The flow rate inside the grouting pipe 8 can be adjusted through the flow regulating mechanism, and the grouting amount can be adjusted according to the needs of the specific working environment.
[0023] Working principle: During the operation of the coal mine tunnel grouting and water blocking equipment, the end of the grouting pipe 8 is placed in the working position to be grouted, and the slurry can be transported to the working position through the grouting pipe 8. The power piece 3 can drive the cleaning rod 5 and the stirring screw 4 to rotate. The cleaning rod 5 can clean the side wall of the first storage shell 1 through the bristles 6, and the slurry inside the first storage shell 1 can be stirred by the stirring screw 4. The slurry inside the first storage shell 1 can be fully mixed to avoid solidification. After the slurry inside the first storage shell 1 is used up, water is sprayed through the nozzle 16 to rinse the inner wall of the first storage shell 1. The cleaning rod 5 continues to rotate to brush the inside of the first storage shell 1 through the bristles, which can avoid residual slurry on the inner wall of the first storage shell 1. The flushing water can be sent into the grouting pipe 8 through the connecting pipe 7 to rinse the inside of the grouting pipe 8, and finally the sewage is discharged through the grouting pipe 8.
[0024] Example 2: Reference Figure 1-4 As another preferred embodiment of the utility model, on the basis of embodiment 1, the flow regulating mechanism includes a mounting shell 9, telescopic rods 10 are fixedly installed on both sides of the mounting shell 9, and baffles 11 are fixedly installed at the ends of the telescopic rods 10. The telescopic rods 10 can drive the baffles 11 to move. The cross-section of the baffle 11 is a semicircular structure, and its diameter is larger than the diameter of the inner wall cross-section of the grouting pipe 8. The two telescopic rods are coaxially arranged, and their extension lines pass through the center axes of the two baffles 11. The baffle 11 is coaxially arranged with the grouting pipe 8. When the two baffles 11 are in contact with each other, the inside of the grouting pipe 8 is closed and the slurry cannot pass through the grouting pipe 8; when the distance between the two baffles 11 becomes larger, more slurry can pass through the grouting pipe 8. By controlling the distance between the baffles 11, the amount of slurry transported by the grouting pipe 8 can be controlled. The pore sizes of different working positions are different, and different slurry amounts are required. Therefore, the grouting amount of the grouting pipe 8 is adjusted according to the specific working environment, which can improve the grouting efficiency. Flanges 12 are fixedly installed at both ends of the baffle 11, and the ends of the flanges 12 are in contact with the side walls of the installation shell 9. The flanges 12 can block both ends of the baffle 11 to prevent slurry from entering the installation shell 9 from both ends of the baffle 11.
[0025] Embodiment 3: In the above embodiment, during the grouting process of the grouting pipe 8, if the water pressure at the outlet of the working surface is high, it is almost impossible to block it with the conventional ordinary slurry. In this case, it is necessary to add aggregates such as crushed stone to the ordinary slurry to form a mixed slurry, and use the mixed slurry to block the working position. For this reason, this embodiment is proposed. Figure 1-3As another preferred embodiment of the utility model, on the basis of embodiment 1 or embodiment 2, an aggregate conveying mechanism is fixedly installed at the bottom of the first storage shell 1, and the aggregate conveying mechanism includes a second storage shell 14, and the second storage shell 14 is fixedly installed at the bottom of the first storage shell 1. Mixed slurry is stored inside the second storage shell 14, and a second connecting pipe 13 is fixedly installed on one side of the bottom of the second storage shell 14. The end of the second connecting pipe 13 is connected to the grouting pipe 8. The second connecting pipe 13 is used to convey the mixed slurry to the grouting pipe 8, and the mixed slurry is injected into the working position through the grouting pipe 8. The plugging is completed when the mixed slurry solidifies.
[0026] When the interior of the first storage shell 1 is flushed through the nozzle 16, the flushing water can not only flush the interior of the grouting pipe 8 through the first connecting pipe 7, but also flush the interior of the second storage shell 14. A connecting valve 15 is fixedly installed on the top of the second storage shell 14 to communicate with the interior of the first storage shell 1. The water inside the first storage shell 1 can be sent into the second storage shell 14 through the connecting valve 15, and the slurry remaining on the inner wall of the second storage shell 14 can be cleaned by water.
[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
