Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-3 As shown, an adjustable mine sealing device includes a sealing pipe 1, a sleeve 3 fixedly mounted on the sealing pipe 1, a grouting bag 4 fixedly mounted on the sleeve 3, a conical sleeve 6 fixedly mounted at one end of the sleeve 3, and an adjusting sleeve 2 movably mounted at the other end; a bearing groove 15 is formed in the middle of the sleeve 3, and protective grooves 14 are formed at both ends of the sleeve 3, symmetrically arranged on both sides of the bearing groove 15; the grouting bag 4 is fixedly mounted inside the bearing groove 15, and a pair of flexible hoses 5 are fixedly mounted on the grouting bag 4, through which... One hose 5 injects grout into the grouting bag 4. The air inside the grouting bag 4 is squeezed by the grout and discharged from the other hose 5. Initially, the discharged air and grout secretion water are discharged, and then it becomes grout containing air bubbles. When the other hose 5 flows out full and uniform grout (i.e., grout without air bubbles), it indicates that the bag is completely filled, and then the hose 5 can be sealed. Limiting holes 13 are symmetrically opened between the protective groove 14 and the bearing groove 15. The hose 5 passes through the limiting holes 13 and is set in the protective groove 14. The adjusting sleeve 2 includes a protective sleeve 7, a sliding adjusting pipe 8, and a dustproof plate 9. The protective sleeve 7 and the sliding adjusting pipe 8 are fixedly connected, and the dustproof plate 9 is fixedly installed at the end of the sliding adjusting pipe 8. Limiting grooves 16 are provided on the protective sleeve 7 and the sliding adjusting pipe 8. A sliding sleeve 12 is fixedly installed on the sealing pipe 1. The sliding sleeve 12 is slidably installed in the limiting groove 16, which can realize the sliding of the adjusting sleeve 2 and limit the distance of the adjusting sleeve 2 moving back and forth. The adjusting sleeve 2 is pushed towards the grouting bag 4 towards the protective sleeve. The protective sleeve 7 covers the grouting bag 4, and the end of the protective sleeve 7 abuts against the conical sleeve 6, thus protecting the grouting bag 4 during installation. To increase the stability of the protection, a slot 11 is provided at one end of the sealing pipe 1 near the dustproof plate 9. A locking block 10 is fixedly provided on the dustproof plate 9. The locking block 10 matches the slot 11. When the adjusting pipe sleeve 2 is pushed, the end of the protective sleeve 7 contacts the conical sleeve 6, and the locking block 10 engages with the slot 11, thereby increasing the stability of the protective sleeve 7 in protecting the adjusting pipe sleeve 2.

[0021] Working principle: During installation, the adjusting sleeve 2 is pushed towards the grouting bag 4 until the protective sleeve 7 covers the grouting bag 4, and the end of the protective sleeve 7 abuts against the conical sleeve 6, thus protecting the grouting bag 4 during installation. When the adjusting sleeve 2 is pushed, the end of the protective sleeve 7 contacts the conical sleeve 6, and the locking block 10 engages with the locking groove 11, thereby increasing the stability of the protective sleeve 7 in protecting the adjusting sleeve 2. Then, the adjusting sleeve 2 is pulled to expose the grouting bag 4, and grout is injected into the grouting bag 4 through a hose 5. The air inside the grouting bag 4 is squeezed by the grout and discharged from the other hose 5. When the other hose 5 flows out full and uniform grout, it indicates that the bag is fully filled, and then the hose 5 can be sealed.
