Description
Technical Field
[0001] The invention relates to the technical fields of mines, tunnels, slopes and the like, and in particular to a multi-stage bag breaking stirring and bag breaking component for a resin anchoring agent. Background Art
[0002] Bolt support technology has been applied in the support of coal mine rock tunnels in my country since the 1950s. After more than 60 years of development, bolt support technology has made great progress in theoretical basis, support materials, construction technology and other aspects. The anchor type has also developed from the initial mechanical anchor to the current resin anchor, and the support body's control and reinforcement ability on the surrounding rock has been significantly improved. When the resin anchor is stirred, the simple anchor rod body cannot fully break the resin anchor bag. Sometimes, after the rod body pierces the bag, the rod body is wrapped by a large area of the resin anchor bag. If the anchor bag is not broken sufficiently, the bag will wrap the resin anchor, causing the resin anchor to be unable to completely bond the anchor (cable) to the surrounding rock of the anchor hole, that is, the so-called "glove phenomenon". This phenomenon is more common in the construction of anchor cable support. The appearance of this phenomenon will cause the anchor (cable) to fail to fully exert the designed support strength, seriously affecting its support quality. Therefore, in view of the above problems, a device with simple structure and easy operation is needed to effectively solve the problem and further improve the anchor support performance. Summary of the invention

[0004] To achieve the above object, the technical solution adopted by the present invention is:
[0005] A multi-stage bag breaking stirring and bag breaking assembly for resin anchoring agent comprises an upper hollow sleeve, the inner wall of the top end of the upper hollow sleeve is fixedly provided with a conical sharp angle, the maximum rotation diameter at the top end of the conical sharp angle is equal to the diameter of the anchoring agent, a plurality of groups of spiral stirring ribs are fixedly provided at intervals on the outer side of the upper hollow sleeve, a plurality of groups of triangular pyramids are fixedly provided on the inner wall of the upper hollow sleeve, the maximum rotation diameter at the top angle of each group of triangular pyramids is equal to the diameter of the anchoring agent, a lower hollow sleeve is fixedly provided at the lower end of the upper hollow sleeve, a spiral stirring blade is fixedly provided on the outer wall of the lower hollow sleeve, a cylinder is installed inside the lower hollow sleeve, and a propeller blade is fixedly provided on the outer side of the cylinder.

[0009] Preferably, the spiral stirring ribs on the outer side of the upper hollow sleeve are arranged in two rows in the axial direction, and the two rows of spiral stirring ribs are respectively arranged on opposite sides of the outer circumference of the upper hollow sleeve.
[0010] Preferably, every three groups of the spiral stirring ribs form a row, the rotation direction of each group of the spiral stirring ribs is left-handed, and the outer wall of the lower hollow sleeve is composed of a plurality of groups of spiral stirring blades.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. Four inner walls of the top of the hollow sleeve are set on the triangular pyramid to achieve a preliminary crushing treatment of the resin anchor. The rotation radius of the center position of the top of the triangular pyramid is consistent with the radius of the anchor to ensure that the top angle of the triangular pyramid is in contact with the resin anchor bag in the maximum range for cutting.

[0014] 3. The lower hollow sleeve is composed of a spiral stirring blade and a propeller blade. Under the action of the spiral stirring blade and the propeller blade, a similar closed sleeve is formed with the rock wall at the same time. Turbulence is formed through a certain rotation speed, so that the anchoring materials can be fully stirred and mixed. Since the spiral stirring blade is a right-handed spiral structure, it is easier for the mixed anchoring materials to fully contact with the rock wall and flow out during the stirring process, thereby enhancing the anchoring effect.
[0015] 4. In summary, the structure is simple, the design is reasonable, the operation is convenient, and the practicability is strong. It can well solve the problem of the simple anchor breaking the anchor bag and the poor mixing ability of the fat anchor in the anchor support construction. When using the same support material and the same anchoring length, the anchor support effect is enhanced to the maximum extent to give full play to the support capacity of the anchor, and further enhance the safety and reliability of the anchor support.

[0024] See also Figure 1-5 An embodiment of the present invention is: a multi-stage bag breaking stirring and bag breaking component of a resin anchor, comprising an upper hollow sleeve 1, a conical sharp corner 2 is fixedly arranged on the inner wall of the top of the upper hollow sleeve 1, the maximum rotation diameter at the top of the conical sharp corner 2 is equal to the diameter of the anchor, a plurality of groups of spiral stirring ribs 3 are fixedly arranged at intervals on the outer side of the upper hollow sleeve 1, a plurality of groups of triangular pyramids 4 are fixedly arranged on the inner wall of the upper hollow sleeve 1, the maximum rotation diameter at the top angle of each group of triangular pyramids 4 is equal to the diameter of the anchor, a lower hollow sleeve 5 is fixedly arranged at the lower end of the upper hollow sleeve 1, a spiral stirring blade 6 is fixedly arranged on the outer wall of the lower hollow sleeve 5, a cylinder 7 is installed inside the lower hollow sleeve 5, and a propeller blade 8 is fixedly arranged on the outer side of the cylinder 7.
[0025] A cross 9 is fixedly provided at the upper end of the cylinder 7. The shape of the cross 9 is a shape with four equal sides. The rotation diameter of the cross 9 around the intersection point and the horizontal diameter of the propeller blade 8 rotating around the cylinder 7 are smaller than the rotation diameter of the spiral stirring blade 6. There are four groups of conical corners 2 on the inner wall of the top end of the upper hollow sleeve 1, and four groups of triangular pyramids 4 are evenly fixed on the inner wall of the top end of the upper hollow sleeve 1, and the top of each group of conical corners 2 is inclined downward.
[0026] When in use, an anchoring borehole is drilled at a predetermined location in the tunnel. After the anchoring borehole construction is completed, the resin anchor is inserted into the anchoring borehole. The anchor rod, under the push of the corresponding drilling rig, pushes the resin anchor to the bottom of the anchoring borehole. After the resin anchor is pushed to the bottom of the anchoring borehole, the rotation switch on the drilling rig is turned on, and the drilling rig drives the anchor rod or anchor cable to rotate. At the same time, the conical sharp corners 2 and the triangular cones 4 on the inner wall of the upper hollow sleeve 1 start to rotate and cut the resin anchor bag. At the same time, the anchor rod continues to advance into the inside of the anchoring borehole. Since the inner wall of the top of the upper hollow sleeve 1 has four groups of conical sharp corners 2, and the inner wall of the upper hollow sleeve 1 is provided with a right spiral path composed of several groups of triangular cones 4, the resin anchor bag is cut and crushed at different positions during rotation. After crushing, the resin anchor raw material moves along The right-handed path flows into the lower hollow sleeve 5, and the spiral stirring blades 6 and the propeller blades 8 in the lower hollow sleeve 5 are used for stirring and mixing. They cooperate with the rock wall to form a similar closed stirring device. When a certain rotation speed is reached, turbulence is formed to make the stirring more sufficient. Four triangular cones 4 are set on the inner wall of the top end of the upper hollow sleeve 1 to achieve a preliminary crushing treatment of the resin anchor. The rotation radius of the center position of the top of the triangular cone 4 is consistent with the radius of the anchor to ensure that the top angle of the triangular cone 4 is in contact with the resin anchor bag in the maximum range for cutting. A right-handed spiral path composed of several groups of triangular cones 4 is set through the inner wall of the upper hollow sleeve 1 to further crush the crushed anchor bag, make it more fully crushed, and at the same time help the downward flow of the anchoring raw materials.
[0027] There are two rows of spiral stirring ribs 3 on the outside of the upper hollow sleeve 1 in the axial direction. The two rows of spiral stirring ribs 3 are respectively arranged on opposite sides of the outer circumference of the upper hollow sleeve 1, and every three groups of spiral stirring ribs 3 form a row. The rotation direction of each group of spiral stirring ribs 3 is left-handed. The outer wall of the lower hollow sleeve 5 is composed of several groups of spiral stirring blades 6.
[0028] At this time, under the joint cutting action of the four groups of conical sharp corners 2 at the top of the upper hollow sleeve 1 and the triangular cone 4 in the upper hollow sleeve 1, the resin anchor bag can be fully broken, avoiding the appearance of too large an area of resin anchor bag, improving the bonding effect between the resin anchoring material and the surrounding rock interface outside the anchoring borehole and the anchor rod interface, and enhancing the supporting quality of the anchor rod. Four triangular cones 4 are set on the inner wall of the top of the upper hollow sleeve 1 to achieve a preliminary crushing treatment of the resin anchor. The rotation radius of the center position of the top of the triangular cone 4 is consistent with the anchor radius to ensure that the top angle of the triangular cone 4 is in contact with the resin anchor bag in the maximum range for cutting. The hollow sleeve composed of the spiral stirring blades 6 and the propeller blades 8 through the lower hollow sleeve 5, under the action of the spiral stirring blades 6 and the propeller blades 8, simultaneously forms a similar closed sleeve with the rock wall, and forms turbulence through a certain rotation speed, allowing the anchoring material to enter The mixed material is fully stirred and mixed. Since the spiral stirring blade 6 is a right spiral structure, it is easier to make the mixed anchoring material fully contact with the rock wall and flow outward during the stirring process, thereby strengthening the anchoring effect. In summary, the structure is simple, the design is reasonable, the operation is convenient, and the practicability is strong. It can well solve the problems of the simple anchor breaking the anchor bag and the poor mixing ability of the fat anchor in the anchor support construction. When using the same support material and the same anchoring length, the anchor support effect is enhanced to the maximum extent, so as to give full play to the support capacity of the anchor, and further enhance the safety and reliability of the anchor support. It is an innovation in the construction process of anchor support technology. The structure can be widely used in support projects such as mines, tunnels, dams, and slopes, effectively improving the defects of anchor bag breakage and poor mixing ability of anchor agents, and avoiding the influence of large pieces of resin anchor bags on the anchoring quality. It has important economic and social benefits.
[0029] Working principle:
[0030] When in use, an anchoring borehole is drilled at a predetermined location in the tunnel. After the anchoring borehole construction is completed, the resin anchor is inserted into the anchoring borehole. The anchor rod, under the push of the corresponding drilling rig, pushes the resin anchor to the bottom of the anchoring borehole. After the resin anchor is pushed to the bottom of the anchoring borehole, the rotation switch on the drilling rig is turned on, and the drilling rig drives the anchor rod or anchor cable to rotate. At the same time, the conical sharp corners 2 and the triangular cones 4 on the inner wall of the upper hollow sleeve 1 rotate to cut the resin anchor bag. At the same time, the anchor rod continues to advance into the anchoring borehole. Since the inner wall of the top of the upper hollow sleeve 1 has four groups of conical sharp corners 2, and the inner wall of the upper hollow sleeve 1 is provided with a right spiral path composed of several groups of triangular cones 4, the resin anchor bag is cut and crushed at different positions during rotation. After crushing, the resin anchor The raw material flows into the lower hollow sleeve 5 along a right-handed path, and is stirred and mixed under the joint action of the spiral stirring blades 6 and the propeller blades 8 in the lower hollow sleeve 5, and cooperates with the rock wall to form a similar closed stirring device, and when it reaches a certain speed, turbulence is formed to make the stirring more complete. Under the joint cutting action of the four groups of conical sharp corners 2 at the top of the upper hollow sleeve 1 and the triangular cone 4 in the upper hollow sleeve 1, the sealed bag of the resin anchor can be fully broken, avoiding the appearance of too large an area of the sealed bag of the resin anchor, improving the bonding effect between the resin anchoring raw material and the surrounding rock interface outside the anchoring borehole and the anchor rod interface, and enhancing the supporting quality of the anchor rod. Four triangular cones 4 are set on the inner wall of the top of the upper hollow sleeve 1 to achieve a preliminary crushing treatment of the resin anchor. The center of the top of the triangular cone 4 The turning radius of the position is consistent with the radius of the anchoring agent to ensure that the top angle of the triangular pyramid 4 contacts the resin anchoring agent sealing bag in the largest range for cutting. A right-handed spiral path composed of several groups of triangular pyramids 4 is set through the inner wall of the upper hollow sleeve 1 to further crush the broken anchoring bag, making it more fully crushed and at the same time facilitating the downward flow of the anchoring material. The lower hollow sleeve 5 is composed of a hollow sleeve composed of a spiral stirring blade 6 and a propeller blade 8. Under the action of the spiral stirring blade 6 and the propeller blade 8, a similar closed sleeve is formed with the rock wall at the same time, and a turbulent flow phenomenon is formed at a certain rotation speed, so that the anchoring material is fully stirred and mixed. Since the spiral stirring blade 6 is a right-handed spiral structure, it is easier to make the mixed anchoring material fully contact with the rock wall during the stirring process. The liquid touches the ground and flows outward to strengthen the anchoring effect. In summary, the structure is simple, the design is reasonable, the operation is convenient, and the practicability is strong. It can well solve the problem of poor ability of anchor bag breakage and fat anchor mixing in anchor cable support construction. When using the same support material and the same anchoring length, the anchor support effect is enhanced to the maximum extent to give full play to the support capacity of the anchor and further enhance the safety and reliability of the anchor support. It is an innovation in the construction process of anchor support technology. The structure can be widely used in support projects such as mines, tunnels, dams, and slopes. It can effectively improve the defects of anchor bag breakage and poor ability to mix anchor agents, and avoid the influence of large resin anchor bags on the anchoring quality. It has important economic and social benefits.
