Description

Technical Field

[0001] This utility model relates to the field of resin anchor technology, specifically to a multifunctional stirring blade. Background Technology

[0002] Currently, resin anchors are widely used in geotechnical, mining, and tunnel engineering, especially in mine roadway support systems. Resin anchors offer advantages such as simple operation, short curing time, and fast construction speed. The conventional resin anchor construction process is as follows: 1. Determine the anchor hole location: Based on design requirements, determine the anchor hole position; 2. Drill the hole: Use a pneumatic drill to drill the hole; 3. Clean the hole: Use high-pressure air to blow out rock powder and remove accumulated water; 4. Fill the hole with resin cartridges as specified; 5. Install the anchor bolt: Use a specialized resin anchor bolt installation machine to install the anchor bolt; 6. Curing: After the resin has cured, tighten the nuts and install the washers.

[0003] Some problems exist in the above construction process. For example, it is necessary to place the resin cartridge into the hole, then push the resin cartridge with the anchor rod, and then squeeze it out at the bottom of the hole to make the anchoring fluid in the resin cartridge flow out and enter the gap between the anchor rod and the hole wall to fill and fix it. However, this method may cause the resin cartridge to get stuck with the anchor rod during the feeding process, resulting in the cartridge not being fed in place.

[0004] Based on this, the utility model application with application number CN202322428598.1 discloses a built-in extrusion type resin cartridge anchor rod. When in use, the resin cartridge is placed into the hollow anchor rod body. The piston extrudes the resin cartridge in conjunction with the blade of the grease-dispensing anchor head, so that when the resin cartridge is extruded and cut, the anchoring agent in the resin cartridge enters the gap between the anchor rod and the hole wall through the through hole of the grease-dispensing anchor head. The piston-type resin cartridge fills the gap between the anchor rod and the hole wall.

[0005] However, this solution still has problems. Since the blade is located on the side wall and the resin cartridge has a certain degree of fluidity, there may be cases where the puncture is not complete. Therefore, greater squeezing force is required to break the resin cartridge and allow the resin anchoring agent to flow into the gap between the anchor rod and the hole wall. In addition, the grease outlet of the grease anchor head is not conducive to the flow of anchoring fluid, and it is still not convenient to use. Summary of the Invention

[0006] To solve the above problems, this utility model provides a multi-functional stirring blade.

[0007] The present invention adopts the following technical solution: a multi-functional agitator, comprising a connecting section, a discharge section and a feeding section connected in sequence as a whole, wherein an inner hole is provided in the connecting section, the discharge section and the feeding section, the inner hole extending from the connecting section into the feeding section, and a plurality of discharge holes are provided in the circumferential direction of the discharge section, all of which communicate with the inner hole.

[0008] In some embodiments, the discharge hole is an oblique hole, and the outlet side of some or all of the discharge holes is inclined toward the side where the connecting section is located.

[0009] In some embodiments, the discharge hole is an oblique hole, and the outlet side of part of the discharge hole is inclined toward the side where the feed section is located.

[0010] In some embodiments, connecting threads are provided on both the inner and outer sides of the connecting section.

[0011] In some embodiments, a plurality of first blades are provided at the end of the connecting section away from the discharge section, and the first blades are provided along the sidewall of the connecting section.

[0012] In some embodiments, a second blade is provided at the lower part of the inner hole, and both ends of the second blade are connected to the hole wall of the inner hole, with the ends of the second blade extending out of the inner hole.

[0013] In some embodiments, the inner hole wall is provided with a mounting groove, and the mounting portion of the second blade is engaged in the mounting groove.

[0014] In some embodiments, the second blade is provided with a plurality of blade tips, which are oriented toward the side away from the feed section.

[0015] In some embodiments, a mounting portion is provided on the side of the feed section away from the connecting section, and a reaming blade is fixedly mounted on the mounting portion.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The multifunctional agitator of this invention has its discharge hole set as an oblique hole, which can promote the flow of the anchoring agent inside after the resin cartridge is punctured, making the flow of the anchoring agent smoother.

[0018] This invention, through the second blade and multiple blade tips set in the inner hole, can better pierce or cut the surface of the resin cartridge, further facilitating the filling of the anchoring agent.

[0019] This invention, through the installation of a reaming blade at the end of the feed section, can break up and remove sediment present in the hole;

[0020] This invention features connecting threads on both the inner and outer sides of the connecting section. When connecting the connecting section to the anchor rod, the connecting threads on both sides allow the anchor rod to be installed either inside or outside the anchor rod. This enables the selection of anchor rods with different diameters, resulting in enhanced functionality. Attached Figure Description

[0029] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] like Figure 1 and Figure 2 As shown, a multi-functional agitator 1 is provided, comprising a connecting section 2, a discharge section 3, and a feeding section 4 arranged sequentially from bottom to top. The connecting section 2, discharge section 3, and feeding section 4 are integrally formed or machined as a single unit. The multi-functional agitator has an inner hole 5 extending from the connecting section into the feeding section 4. Multiple discharge holes 301 are provided circumferentially in the discharge section 3. Specifically, there can be 3-5 discharge holes 301, evenly spaced around the circumference of the discharge section. This number of discharge holes ensures the strength of the discharge section 3 while facilitating the smooth flow of anchoring agent. All discharge holes 301 communicate with the inner hole 5, and one or more of the discharge holes 301 are oblique holes.

[0031] The implementation principle is:

[0032] In existing technologies, when the anchoring agent is extruded, it first flows straight out along the discharge hole 301 and then flows outwards under the constraint of the hole wall. There is a power loss when it comes into contact with the hole wall, which is not conducive to the smooth flow of the anchoring agent. The difference in this embodiment is that, since the discharge hole 301 is set at an angle, the anchoring agent inside will flow out along the hole wall of the discharge hole, which plays a guiding role. Compared with the existing technology, the flow of the anchoring agent is smoother.

[0033] like Figure 2 As shown, some or all of the discharge holes 301 are inclined toward the side where the connecting section 2 is located; when all the discharge holes 301 are inclined along the connecting section, the anchoring agent can flow more smoothly to the side where the connecting section 2 is located; when some of the discharge holes 301 are inclined, the anchoring agent will flow in different directions and can fill the gap between the anchor rod and the hole wall from different directions; the inclination angle of the discharge hole is preferably 29-65°. If the inclination is too small, it will not have the effect of assisting the flow of the anchoring agent; if it is too large, it will affect the strength.

[0034] A portion of the discharge hole 301 is inclined toward the side where the feed section 4 is located. Because a portion of the discharge hole 301 is inclined toward the feed section 4, it is easier for the anchoring agent to fill the gap between the feed section 4 and the hole wall, making the connection on the feed section 4 side more stable.

[0035] like Figure 3 As shown, connecting threads 201 are provided on both the inner and outer sides of the connecting section 2. When the connecting section 2 is connected to the anchor rod, the connecting threads 201 provided on both the inner and outer sides of the connecting section 2 can be installed on either the inner or outer side of the anchor rod, allowing for the selection of anchor rods with different diameters and enhancing functionality.

[0036] like Figure 3 As shown, a number of first blades 202, specifically 2-4, are provided at the bottom of the connecting section 2, which can pierce the resin cartridge at different angles; the number of first blades 202 provided on the connecting section 2 can pierce or cut the resin cartridge when it is pushed to the location of the first blade 202, thereby allowing the anchoring agent in the resin cartridge to flow out smoothly.

[0037] like Figure 4 and Figure 5 In this embodiment, a second blade 501 is provided in the middle of the inner hole 5, and the two ends of the second blade 501 are connected to the hole wall of the inner hole 5. By providing the second blade 201 in the middle of the inner hole 5, the resin cartridge can be directly pierced or cut from the middle, avoiding the difficulty in the outflow of anchoring agent caused by the first blade 202 in the connecting section 2 failing to cut the resin cartridge.

[0038] In this embodiment, as Figure 2 and Figure 5The inner hole 5 has a mounting groove 502 on its wall. Specifically, the mounting groove 502 can extend directly into the discharge section 3 or even the feed section 4. The two horizontal ends of the second blade 501 are engaged in the mounting groove and can be fixed by welding and bonding. Engaging the second blade 501 in the mounting groove 502 facilitates the installation and positioning of the second blade 501. When the second blade 501 needs to be further fixed, the operation is convenient.

[0039] In specific implementation, such as Figure 4 Multiple blade tips 503 are provided on the second blade 501. The blade tips 503 can be serrated for easy processing. The blade tips 503 all point downwards. By setting multiple blade tips 503, the resin cartridge can be pierced or cut more effectively. At the same time, due to their small thickness, they will not cause too much obstruction to the flow of anchoring agent after piercing.

[0040] like Figure 6 As shown, an integral mounting part 401 is formed on the upper end of the feed section 4, and a cleaning and reaming blade 402 is welded on the mounting part 401. Through the action of the mounting part 401 and the cleaning and reaming blade 402, when the multi-functional agitator 1 is inserted into the hole and rotates, it can break up the sediment in the hole and also achieve the effect of stirring the resin anchoring agent evenly, thus having a greater function.

[0041] Specifically, the mounting part 401 or the reaming blade 402 is inclined to the side where the center of the feed section is located, or both have a certain direction of rotation; through such an inclined setting, the contact surface between the feed part 4 and the bottom of the hole is effectively increased, making it easier to fix the multi-functional stirring blade 1.

[0042] The multifunctional agitator 1 of this invention features an oblique discharge hole 301, which promotes the flow of the anchoring agent after the resin cartridge is punctured, making the flow of the anchoring agent smoother. The second blade 501 and its multiple blade tips 503, located in the inner hole, can better puncture or cut the surface of the resin cartridge, further aiding in the filling of the anchoring agent. The cleaning blade 402 at the end of the feed section 4 can break up and remove sediment present in the hole. The connecting threads 201 on both the inner and outer sides of the connecting section allow the connecting section 2 to be installed on either the inner or outer side of the anchor rod when connecting to the anchor rod, enabling the selection of anchor rods with different diameters and enhancing functionality.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims.
