Description

Technical Field

[0001] The utility model relates to the technical field of anchor rods, in particular to an automatic dosing and self-rotating anchor rod. Background Art

[0002] Anchor rods are the most basic component of tunnel support in modern coal mines. Anchor rods can reinforce the surrounding rocks of the tunnels so that the surrounding rocks can support themselves. In the prior art, the anchor rods are fixed by first machining anchor holes on the rock wall, then inserting the anchor rods to be fixed into the anchor holes, and then inserting the drug bag containing the anchoring agent into the designated position between the anchor hole and the anchor rod, puncturing the drug bag, and completing the fixing of the anchor rod after the anchoring agent fills the hole and solidifies. The above fixing method has the following problems:

[0003] 1. Limited anchor rod diameter: The diameter of the anchor rod is usually small, so it is easy for the anchor rod to get stuck when delivering medicine, resulting in the anchor rod being unable to be fixed in place.

[0004] 2. Irregular shape of medicine package: Medicine package is usually irregular in shape, which requires ensuring that it can smoothly pass through the anchor hole to reach the anchoring section when delivering the medicine, and it is also necessary to ensure that the medicine package is evenly distributed in the anchor hole of the anchor section.

[0005] 3. The medicine package is thin: Some medicine packages are thin and are prone to damage and leakage during the delivery process, which will affect the normal use and anchoring effect of the medicine package.

[0006] 4. The inner wall of the anchor hole is not smooth enough: The smoothness of the inner wall of the anchor hole will affect the delivery of the medicine bag. If the inner wall is not smooth, the medicine bag will easily get stuck.

[0007] 5. Anchor holes are prone to collapse: In some areas with poor geological conditions, anchor holes are prone to partial collapse, resulting in the inability to directly deliver anchor drugs into the hole.

[0008] The above problems will lead to the failure of anchor fixation, so an anchor that can bring the medicine bag directly into the anchor hole is needed. Utility Model Content
