A buffer ring 202d is fixedly installed on the inner side of the second limit ring, and the inner side of the buffer ring 202d is tightly fitted with the surface of the filling tube 101.

[0031] As a technical optimization solution of the present invention, by setting a buffer component 202, the buffer spring 202b is fixed by the first limit block 202a and the second limit block 202c, so that when the buffer ring 202d is subjected to force, it can be transmitted to the buffer spring 202b through the second limit block 202c, so that the buffer spring 202b can buffer a certain impact force, thereby achieving a buffering effect.

[0032] refer to Figure 2 The adjustment component 205 includes an adjustment slot 205a, which is provided inside the adjustment plate 204. An extension plate 205b is slidably installed inside the adjustment slot 205a. Adjustment holes 205c are provided inside the extension plate 205b and the adjustment plate 204. There are a number of adjustment holes 205c distributed at equal distances. A fixing component 205d is inserted into the adjustment hole 205c, and an adaptor support component 205e is fixedly installed at the bottom end of the extension plate 205b.

[0033] As a technical optimization solution of the present invention, by providing the adjustment component 205, the extension plate 205b can be adjusted to any length through the adjustment slot 205a to adapt to the length in contact with the ground after unfolding, thereby ensuring the stability of the reinforcement.

[0034] refer to Figure 3 The fixing component 205d includes a butterfly bolt 205e-1, which is inserted into the adjusting hole 205c, and the other end of the butterfly bolt 205e-1 is threadedly connected with a nut 205e-2.

[0035] As a technical optimization solution of the present invention, by providing a butterfly bolt 205e-1 and a nut 205e-2, it is convenient for the user to fix the adjusted extension plate 205b through the butterfly bolt 205e-1 and the nut 205e-2, thereby preventing the extension plate 205b from falling off and ensuring the stability after adjustment.

[0036] refer to Figure 4 The adapting support component 205e includes a support block 205e-1205e-1, which is fixedly installed on the other end of the extension plate 205b. An adapting groove 205e-2 is provided inside the support block 205e-1205e-1, and an adapting rod 205e-3 is movably installed inside the adapting groove 205e-2.

[0037] As a technical optimization solution of the present invention, by setting an adapter support component 205e, after the support block 205e-1205e-1 is fixed to the other end of the extension plate 205b, it is movably installed through the adapter groove 205e-2 and the adapter rod 205e-3, which facilitates the adjustment of the support angle and ensures the stability of the reinforcement.

[0038] refer to Figure 4 , adapter blocks 205e-4 are fixedly installed at both ends of the adapter rod 205e-3, and a support rod 205e-5 is fixedly installed at the bottom of the adapter block 205e-4.

[0039] As a technical optimization solution of the present invention, by setting the adapter block 205e-4 and the support rod 205e-5, the adapter block 205e-4 and the support rod 205e-5 can be adjusted and plugged into the ground, thereby ensuring the stability of the reinforcement.

[0040] refer to Figure 4 An adjustment rod 205e-6 is fixedly installed on the outer side of the adapter block 205e-4.

[0041] As a technical optimization solution of the present invention, by setting the adjustment rod 205e-6, the user can adjust the angle of the adapter block 205e-4 and the support rod 205e-5 through the adjustment rod 205e-6, thereby ensuring the stability of the support rod 205e-5 in contact with the ground.

[0042] refer to Figure 4 An anti-slip pad is fixedly installed on the inner side of the buffer ring 202d.

[0043] As a technical optimization solution of the present invention, by setting an anti-skid pad, the anti-skid pad can increase the friction between the buffer ring 202d and the filling tube 101, thereby ensuring the stability of the reinforcement.

[0044] The working principle and use process of the present invention are as follows: when in use, the additive is added from a straight tube with a middle diameter of 30mm to the middle circular ring between the two circular tubes. The inner circular tube has many fine holes 102 with a diameter of 6mm and is inclined in the direction of paste conveying. The maximum aggregate of the filling paste conveyed inside the middle circular hole is 10mm to prevent excessive paste from flowing in reverse. While the paste is being conveyed, the additive with a certain pressure is added to the middle filling paste more evenly from the 6mm fine hole 102. The additive is pressurized and conveyed from the side DN25 circular tube to the closed space of the inner and outer annular tubes, and then evenly enters the inner tube of the adding device from numerous fine holes to mix with the filling material. The fine hole diameter is 6mm, and the maximum particle size of the filling material is 10mm. The device plays the role of a check valve for uniform material distribution. In order to ensure the stability of the filling mechanism 1 during filling, first separate the butterfly bolt 205e-1 and the nut 205e-2 to facilitate the user to adjust the length of the extension plate 205b and the adjustment groove 205a inside the adjustment plate 204. After the adjustment is completed, The adjusting plate 204 and the extension plate 205b are fixed by the butterfly bolt 205e-1 and the nut 205e-2, and then the adjusting rod 205e-6 is toggled to make the adjusting rod 205e-6 drive the adapting block 205e-4 and the supporting rod 205e-5 to adjust, so that the supporting rod 205e-5 and the adapting block 205e-4 can be adjusted in angle through the adapting rod 205e-3 and the adapting groove 205e-2, so that the supporting rod 205e-5 is in contact with the ground for support, and then the adjusting plate 20 The movable frame 203 drives the buffer ring 202d to fit closely with the top of the surface of the filling tube 101 through the reinforcement ring 201, so that the four can simultaneously squeeze inward to clamp and reinforce the filling tube 101, and when the filling tube 101 is subjected to impact force during filling, the impact force is transmitted to the buffer ring 202d, so that the buffer ring 202d transmits the impact force to the buffer spring 202b through the second limit block 202c, so that the buffer spring 202b buffers the impact force, thereby ensuring the stability of the reinforcement.

[0045] In summary, the device for adding additives to mine filling, by setting a filling mechanism 1, allows the additive to be filled through the filling mechanism 1, and then allows the reinforcing mechanism 2 to reinforce the filling mechanism 1 during filling, thereby avoiding the tilting situation, ensuring the stability of the filling, and solving the problem of adding additives (generally early strength agent or quick setting agent) to the stirring mechanism at the front end of the filling system in a traditional way, which has obvious advantages;

[0046] First, the addition of additives at the front end affects the fluidity of the material, which leads to poor conveying effect of the filling material in the filling pipeline;

[0047] 2. When a pipe blockage accident occurs in the filling pipeline, the material added with early strength agent or quick setting agent will solidify quickly in the filling pipeline, which will cause the entire filling pipeline to be scrapped, resulting in huge economic losses and delays in construction period.
