Description

Technical Field

[0001] The utility model relates to the technical field of mining and excavation construction equipment and peripheral supporting facilities, in particular to a drug delivery anchor rod. Background Art

[0002] During the excavation of mine tunnels and highway tunnels, anchor rods are used to transport drug bags to ensure smooth mining and excavation. Since the diameter of the anchor rod is usually small, it is easy to get stuck in the anchor rod when delivering drugs, resulting in the inability to fix the anchor rod in place. At the same time, the drug bags are usually irregular in shape. When delivering drugs, it is necessary to ensure that the drug bags pass through the anchor rod hole to reach the anchoring section, which is difficult to operate. It is also necessary to ensure that the drug bags are evenly distributed in the anchoring section of the anchor rod hole; in addition, since the drug bag packaging is thin, it is easy to be damaged and leaked during the drug delivery process, affecting the normal use of the drug bag and the anchoring effect of the anchor rod. In addition, the smoothness of the anchor rod hole will also affect the delivery of the drug bag. If the inner wall of the anchor rod hole is not smooth, the drug bag is easy to get stuck. For some places with poor geological conditions, the anchor rod hole is prone to partial collapse, resulting in the inability to directly deliver the anchor drug into the hole.

[0003] The existing medicine delivery methods mainly include manual medicine delivery, air pressure medicine delivery, hydraulic medicine delivery, vibration medicine delivery and spiral medicine delivery. Manual drug delivery is to manually deliver the drug bag into the anchor hole. Manual drug delivery is inefficient and the drug bag may get stuck or damaged due to improper operation. Pneumatic drug delivery is to use the air pressure difference to deliver the drug bag into the anchor hole through the drug delivery tube. Pneumatic drug delivery has the advantages of simple operation and low cost, but unstable air pressure will affect the stability and reliability of drug delivery. Hydraulic drug delivery is to use the hydraulic principle to push the drug bag into the anchor hole through the drug delivery tube. Hydraulic drug delivery has the advantages of strong drug delivery force and high reliability, but it requires special hydraulic equipment and is relatively expensive. Vibration drug delivery is to use a vibrator to vibrate the drug bag into the anchor hole. This method is suitable for soft soil layers. The drug bag can be smoothly entered into the anchor hole through vibration, but the vibration will affect the surrounding soil layers and needs to be used with caution. Spiral drug delivery is to use spiral blades to push the drug bag into the anchor hole. The design of the spiral blades needs to take into account factors such as the diameter and length of the anchor hole, and it has a greater impact on the hole-forming effect.

[0004] Therefore, how to solve the above problems and improve the reliability of drug delivery while ensuring the quality of anchoring has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0029] The drug delivery anchor rod of the utility model is connected with a stirrer 2 at the front end of the anchor rod body 1, and a drug charging sleeve 3 is added. The drug charging sleeve 3 includes a sleeve nut 4 and a sleeve body 5. The inner cavity of the sleeve body 5 can accommodate multiple anchor drug packages 7. The sleeve body 5 can protect the drug packages from being scratched or stuck during the drug delivery process, thereby improving the reliability and efficiency of drug delivery. The sleeve nut 4 is threadedly connected to the anchor rod body 1, so that the anchor rod body 1 can drive the stirrer 2 to rotate to puncture the anchor drug package. 7 and stir the anchoring agent. When it reaches the anchoring section of the borehole, the stirrer 2 stirs the anchoring agent evenly and pushes the anchoring agent to flow out from the agent outlet 6 and evenly distribute it in the anchoring section to enhance the anchoring effect. The anchor rod body 1 is a full-threaded structure, which is threadedly connected with the casing nut 4. The structure is simple and compact. While the anchoring agent is pushed out from the inner cavity of the casing body 5, the anchor rod body and the charge casing 3 produce axial relative displacement, so that the charge casing 3 is smoothly moved out of the anchoring section, further ensuring the anchoring effect.

[0030] Among them, the casing body 5 can protect the anchor agent package 7. In order to smoothly export the anchor agent, the agitator 2 has a protruding structure 8 facing the direction of the loaded casing 3. The protruding structure 8 can pierce the anchor agent package 7 in the casing body 5. After piercing the anchor agent package 7, the agitator 2 rotates with the anchor rod body 1 to stir the anchor agent so that the anchor agent is evenly exported.
