Resin anchoring agent bag breaking and stirring device and bag breaking and stirring method

Abstract

The invention discloses a resin anchoring agent bag breaking and stirring device which comprises a sleeve. An opening is formed in the lower end of the sleeve, at least two breaking cutters are uniformly and fixedly arranged at the top of the sleeve along a peripheral direction, the maximum rotation diameter of each breaking cutter is equal to the outer diameter of the sleeve, and a plurality of screw stirring ribs are arranged on the periphery of the sleeve at intervals. The invention further discloses a resin anchoring agent bag breaking and stirring device method. The device is simple in structure, convenient to use, reasonable in design and high in practicability and can effectively solve the problems that breaking effects of resin anchoring agent bags are not ideal, and anchoring force is affected in a current anchor rod or anchor cable support. An efficient device is provided for breaking of the resin anchoring agent bags, stirring effects of resin anchoring agents can be effectively improved, materials in the resin anchoring agent are more sufficiently mixed, important guarantee is improved for improvement of quality of the anchor rod or anchor cable support, a constructionprocess of an anchor rod or anchor cable support technique is innovated, and the device has great social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of roadway (tunnel) support, and in particular relates to a bag-breaking stirring device for a resin anchoring agent and a bag-breaking stirring method thereof. Background technique [0002] Bolt support technology has been applied in coal mine roadway support in my country since 1956. After more than 60 years of development, it has made great progress and made great contributions to the safe production of coal in our country. In the support of lanes (tunnels), a large amount of anchor rods (cables) and resin anchoring agents will be used. Since the resin anchoring agent envelopes currently used are made of plastic, they are soft and strong, and when using anchor rods (cable) for support, generally only rely on the force of the anchor rod (cable) when it rotates to destroy the resin anchoring agent envelope, sometimes by sharpening the top of the anchor rod (cable) to destroy the resin anchoring agent envelo...

AI Technical Summary

Problems solved by technology

In the support of lanes (tunnels), a large amount of anchor rods (cables) and resin anchoring agents will be used. Since the resin anchoring agent envelopes currently used are made of plastic, they are soft and strong, and when using anchor rods (cable) for support, generally only rely on the force of the anchor rod (cable) when it rotates to destroy the resin anchoring agent envelope, sometimes by sharpening the top of the anchor rod (cable) to destroy the resin anchoring agent envelope purpose, but the effect is not satisfactory

If the resin anchoring agent envelope is not completely broken, it will cause insufficient stirring of the resin anchoring agent. At the same time, when a large area of ​​resin anchoring agent envelope is located between the anchoring hole wall and the anchor rod (cable), it will seriously affect the resin anchoring. The bonding effect between the agent and the hole wall significantly reduces the anchoring force of the anchor rod (cable), and even causes the anchoring quality of the anchor rod (cable) to fail to meet the requirements. The phenomenon that the resin anchoring agent cannot normally bond with the surrounding rock of the anchored drilling hole and affect the support effect of the anchor rod (cable) is called the "glove phenomenon".
