[0002] With the increasing global demand for mineral resources, the mining industry, as a key resource development sector, faces enormous challenges in improving mining efficiency, ensuring operational safety, and protecting the environment. In the mining process, mine backfilling drilling is one of the key technologies for achieving safe and environmentally friendly mining. Paste backfilling is a technology that mixes solid materials with water or other liquids in a certain proportion to form a paste-like slurry, which is then transported to a designated area (such as an underground goaf) via pipeline using a backfilling pump or gravity pressurization. However, current backfilling methods do not allow for the pre-solidification of the additives needed for backfilling. Traditional methods are required to add the additives to the designated area for backfilling, which is cumbersome and cannot pre-solidify the additives, thus reducing backfilling efficiency. Summary of the Invention

[0003] To address the problems mentioned in the background art, the present invention aims to provide a mine backfilling additive addition device, which has the advantage of improving the efficiency of backfilling operations. It solves the problem that current backfilling methods do not have the effect of pre-solidifying the additives to be filled, requiring the addition of additives to the designated area in a traditional manner. The transmission method of backfilling is cumbersome and cannot pre-solidify the additives to be filled, thus reducing the backfilling efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a mine backfilling additive adding device, comprising a backfilling mechanism, the backfilling mechanism including a backfilling pipe, the backfilling pipe having a plurality of fine holes arranged in a ring at equal intervals, and a reinforcing mechanism located on the surface of the backfilling mechanism, the reinforcing mechanism including four reinforcing rings arranged in a ring at equal intervals, a buffer assembly fixedly installed on the inner side of the reinforcing rings, a movable frame fixedly installed on the outer side of the reinforcing rings, an adjusting plate movably installed on the inner side of the movable frame, and an adjusting assembly slidably installed on the inner side of the adjusting plate.

[0005] In a preferred embodiment of the present invention, the buffer assembly includes a first limiting block, which is fixedly installed on the inner side of the reinforcing ring. A plurality of the first limiting blocks are provided and are distributed at equal intervals. A buffer spring is fixedly installed on the surface of the first limiting block, and a second limiting block is fixedly installed on the other end of the buffer spring. A buffer ring is fixedly installed on the inner side of the second limiting block, and the inner side of the buffer ring is in close contact with the surface of the filling tube.

[0006] In a preferred embodiment of the present invention, the adjusting component includes an adjusting groove, which is formed inside the adjusting plate. An extension plate is slidably installed inside the adjusting groove. Adjusting holes are formed inside both the extension plate and the adjusting plate. Several adjusting holes are formed and are evenly distributed. A fixing component is inserted into the adjusting hole. An adapter support component is fixedly installed at the bottom end of the extension plate.

[0007] As a preferred embodiment of the present invention, the fixing component includes a wing bolt, which is inserted into the adjustment hole, and the other end of the wing bolt is threaded with a nut.

[0008] As a preferred embodiment of the present invention, the adapter support component includes a support block, which is fixedly installed at the other end of the extension plate. An adapter groove is provided inside the support block, and an adapter rod is movably installed inside the adapter groove.

[0009] As a preferred embodiment of the present invention, adapter blocks are fixedly installed at both ends of the adapter rod, and a support rod is fixedly installed at the bottom of the adapter block.

[0010] As a preferred embodiment of the present invention, an adjusting rod is fixedly installed on the outer side of the adapter block.

[0011] As a preferred embodiment of the present invention, an anti-slip pad is fixedly installed on the inner side of the buffer ring.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. This invention, by setting up a filling mechanism, allows the additive to be filled through the filling mechanism, and then uses a reinforcing mechanism to reinforce the filling mechanism during filling, avoiding tilting and ensuring filling stability. It solves the problem that current filling methods do not have the effect of pre-solidifying the additives to be filled, requiring the addition of additives to the designated area by traditional methods, which is cumbersome and cannot pre-solidify the additives to be filled, thus reducing filling efficiency. This invention achieves the effect of improving the efficiency of filling operations.

[0014] 2. The present invention sets up a buffer component so that the buffer spring is fixed by the first limit block and the second limit block. When the buffer ring is subjected to force, it can be transmitted to the buffer spring through the second limit block, so that the buffer spring can buffer a certain impact force, thereby achieving the buffering effect.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, the present invention provides a mine filling additive addition device, including a filling mechanism 1, the filling mechanism 1 including a filling pipe 101, the inner side of the filling pipe 101 having a number of fine holes 102 arranged in a ring and evenly distributed, and a reinforcing mechanism 2, the reinforcing mechanism 2 being located on the surface of the filling mechanism 1, the reinforcing mechanism 2 including a reinforcing ring 201, four reinforcing rings 201 arranged in a ring and evenly distributed, a buffer component 202 fixedly installed on the inner side of the reinforcing ring 201, a movable frame 203 fixedly installed on the outer side of the reinforcing ring 201, an adjusting plate 204 movably installed on the inner side of the movable frame 203, and an adjusting component 205 slidably installed on the inner side of the adjusting plate 204.

[0024] refer to Figure 5 The buffer assembly 202 includes a first limiting block 202a, which is fixedly installed on the inner side of the reinforcing ring 201. Several first limiting blocks 202a are provided and are distributed at equal intervals. A buffer spring 202b is fixedly installed on the surface of the first limiting block 202a. A second limiting block 202c is fixedly installed on the other end of the buffer spring 202b. A buffer ring 202d is fixedly installed on the inner side of the second limiting block 202c. The inner side of the buffer ring 202d is in close contact with the surface of the filling tube 101.

[0025] As a technical optimization of the present invention, by setting up a buffer assembly 202, the buffer spring 202b is fixed by the first limiting block 202a and the second limiting 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 limiting block 202c, so that the buffer spring 202b can buffer a certain impact force, thereby achieving the buffering effect.

[0026] refer to Figure 2 The adjustment component 205 includes an adjustment groove 205a, which is opened inside the adjustment plate 204. An extension plate 205b is slidably installed inside the adjustment groove 205a. Both the extension plate 205b and the adjustment plate 204 have adjustment holes 205c. Several adjustment holes 205c are opened and are evenly distributed. A fixing component 205d is inserted into the adjustment hole 205c. An adapter support component 205e is fixedly installed at the bottom end of the extension plate 205b.

[0027] As a technical optimization of the present invention, by setting the adjustment component 205, the extension plate 205b can be adjusted to any length through the adjustment groove 205a to adapt to the length in contact with the ground after unfolding, thus ensuring the stability of the reinforcement.

[0028] refer to Figure 3 The fixing component 205d includes a wing bolt 205d-1, which is inserted into the adjustment hole 205c. The other end of the wing bolt 205d-1 is threaded with a nut 205d-2.

[0029] As a technical optimization of the present invention, by setting the wing bolt 205d-1 and nut 205d-2, it is convenient for the user to fix the adjusted extension plate 205b with the wing bolt 205d-1 and nut 205d-2, so as to avoid the extension plate 205b from falling off and ensure the stability after adjustment.

[0030] refer to Figure 4The adapter support component 205e includes a support block 205e-1, which is fixedly installed at the other end of the extension plate 205b. An adapter groove 205e-2 is provided inside the support block 205e-1, and an adapter rod 205e-3 is movably installed inside the adapter groove 205e-2.

[0031] As a technical optimization of the present invention, by setting an adapter support component 205e, after the support block 205e-1 is fixed to the other end of the extension plate 205b, it is movably installed with the adapter rod 205e-3 through the adapter groove 205e-2, which facilitates the adjustment of the support angle and ensures the stability of the reinforcement.

[0032] refer to Figure 4 The adapter rod 205e-3 has adapter blocks 205e-4 fixedly installed at both ends, and the adapter block 205e-4 has a support rod 205e-5 fixedly installed at the bottom.

[0033] As a technical optimization 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 inserted into the ground, thus ensuring the stability of the reinforcement.

[0034] refer to Figure 4 An adjusting rod 205e-6 is fixedly installed on the outer side of the adapter block 205e-4.

[0035] As a technical optimization of the present invention, by setting the adjustment rod 205e-6, the user can easily adjust the angle of the adapter block 205e-4 and the support rod 205e-5 by adjusting the adjustment rod 205e-6, thus ensuring the stability of the support rod 205e-5 in contact with the ground.

[0036] refer to Figure 4 An anti-slip pad is fixedly installed on the inner side of the buffer ring 202d.

[0037] As a technical optimization of the present invention, by setting an anti-slip pad, the anti-slip pad can increase the friction between the buffer ring 202d and the filling tube 101, thus ensuring the stability of the reinforcement.

[0038] The working principle and usage process of this invention are as follows: During use, the additive is added from the 30mm diameter straight tube to the central ring between the two circular tubes. The inner circular tube has many 6mm diameter fine holes 102, which are inclined towards the direction of paste delivery. The maximum aggregate size for filling the paste inside the central hole is 10mm to prevent excessive paste from flowing backward. While the paste is being delivered, the additive, under certain pressure, is added relatively evenly to the central filling paste through the 6mm fine holes 102. To ensure the stability of the filling mechanism 1 during filling, the wing bolt 205d-1 and nut 205d-2 are first separated to facilitate the user's adjustment of the length of the extension plate 205b and the internal adjustment groove 205a of the adjustment plate 204. After adjustment, the adjustment plate 204 and extension plate 205b are fixed by the wing bolt 205d-1 and nut 205d-2, and then the adjustment is made by turning the lever. The rod 205e-6 drives the adapter block 205e-4 and support rod 205e-5 to adjust, allowing the support rod 205e-5 and adapter block 205e-4 to be angled via the adapter rod 205e-3 and adapter groove 205e-2, so that the support rod 205e-5 contacts the ground for support. Then, the adjusting plate 204, through the movable frame 203 and the reinforcing ring 201, drives the buffer ring 202d to fit tightly against the top of the filling tube 101 surface, so that the four can simultaneously squeeze inward to clamp and reinforce the filling tube 101. When the filling tube 101 is subjected to impact force during filling, the impact force is transmitted to the buffer ring 202d, which in turn transmits the impact force to the buffer spring 202b through the second limiting block 202c, so that the buffer spring 202b buffers the impact force and ensures the stability of the reinforcement.

[0039] In summary, this mine filling additive addition device, by setting up a filling mechanism 1, allows the additive to be filled through the filling mechanism 1, and then the reinforcing mechanism 2 reinforces the filling mechanism 1 during filling to prevent tilting and ensure filling stability. It solves the problem that current filling methods do not have the effect of pre-solidifying the additives to be filled, and require the use of traditional methods to add the additives to the designated area for filling. The transmission method of filling is cumbersome and cannot pre-solidify the additives to be filled, thus reducing filling efficiency.
