Description

Technical Field

[0001] This utility model relates to the field of mixing blade technology, and in particular to a wear-resistant mixing blade device for grouting materials. Background Technology

[0002] Grouting is a technique that uses methods such as replacement, filling, and extrusion to inject a solidifiable grout into rock and soil or structural cracks to improve the target physical and mechanical properties. It is commonly used in fields such as construction engineering, ceramics, mining, and underground engineering. During the grouting process, the grout needs to be stirred to ensure that it is mixed evenly, thereby improving the quality and performance of the grouting material.

[0003] Chinese patent CN218221910U discloses a submersible mixer impeller. The key technical features are: a hub and multiple blades arranged circumferentially around the hub; each blade has an inner and outer edge, with serrations on the outer edge; and each blade also has a secondary impeller. This application, by employing a blade structure with cutting capabilities, effectively agitates the water flow, ensuring the thorough dispersal of clumps of mud. The secondary impellers ensure agitation in areas inaccessible to the blades, guaranteeing optimal mixing performance.

[0004] Existing related technologies often have the following drawbacks: during the process of using a mixing blade to mix the grouting material, due to the high particle size and roughness of the grouting material, there is a strong friction between the mixing blade and the grouting material, which makes the mixing blade easily damaged due to friction with the grouting material.

[0005] Therefore, this utility model provides a wear-resistant grouting material mixing and stirring blade device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where, during the mixing of grouting materials using stirring blades, the high particle size and roughness of the grouting materials lead to strong friction between the stirring blades and the grouting materials, making the stirring blades prone to damage due to friction. Therefore, this invention proposes a wear-resistant grouting material mixing and stirring blade device.

[0011] Preferably, the inner wall of the wheel hub is threaded with six adjusting screws, and all six adjusting screws are rotatably connected to the limiting strip.

[0012] The effect achieved by the above components is that the movement of the limit bar can be controlled by the adjusting screw, and the wheel hub can restrict the rotation of the limit bar during the process of controlling the movement of the limit bar by adjusting the screw.

[0013] Preferably, a first clamping plate is fixedly connected to the side of the first connecting plate, and a second clamping plate is fixedly connected to the side of the second connecting plate. Both the first clamping plate and the second clamping plate are tightly fitted to the blade body.

[0014] The effect achieved by the above components is that by setting the first clamping plate and the second clamping plate, the first connecting plate and the second connecting plate can be connected to the blade body.

[0017] Preferably, four limiting rods are fixedly connected to the side of the rotating ring, and all four limiting rods are slidably connected to the inner wall of the second clamping plate. A handle is fixedly connected to the side of the rotating ring away from the blade body.

[0018] The above components achieve the following effects: by setting a limiting rod, a stable connection between the rotating ring and the second card plate is ensured without affecting the rotation of the rotating ring; and by setting a handle, the rotation of the rotating ring can be easily controlled.

[0019] Preferably, the first connecting plate and the second connecting plate are provided with a plurality of sliding grooves on the side near the inclined baffle.

[0020] The above components achieve the following effects: the slider ensures the movement and stable installation of the inclined baffle; the slider and spring provide a buffering effect for the inclined baffle.

At the same time, the blade body can be easily replaced by the adjusting screw and the limiting strip. This avoids the need to replace the entire stirring blade when the inclined baffle or the blade body suffers severe friction damage, thus reducing the cost of use. Attached Figure Description

[0031] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a wear-resistant grouting material mixing and stirring impeller device, including a hub 1, with three impeller bodies 2 installed inside the hub 1. The three impeller bodies 2 are slidably connected to the inner wall of the hub 1. A first connecting plate 3 is slidably connected to the side of each of the three impeller bodies 2, and a second connecting plate 4 is slidably connected to the side of each of the three impeller bodies 2 away from the first connecting plate 3. An inclined baffle 5 is installed on the side of the first connecting plate 3 and the second connecting plate 4 that is away from each other. Through the first connecting plate 3 and the second connecting plate 4, the inclined baffle 5 can be installed on the impeller body 2. The inclined surface of the inclined baffle 5 can reduce the frictional damage caused by the grouting material, and the inclined baffle 5 can protect the impeller body 2.

[0032] The following is a detailed explanation of its overall setup and function.

[0033] Reference Figures 1-6 As shown in this embodiment: three positioning rods 6 are fixedly connected to the inner wall of the hub 1, and all three positioning rods 6 are slidably connected to the inner wall of the blade body 2. Six limiting strips 7 are installed inside the hub 1, and all six limiting strips 7 are slidably connected to the inner wall of the blade body 2. The positioning rods 6 can be used to position the blade body 2 when it is installed on the hub 1, and the limiting strips 7 can restrict the position of the blade body 2 after it is connected to the hub 1. Six adjusting screws 8 are threaded into the inner wall of the hub 1, and all six adjusting screws 8 are rotatably connected to the limiting strips 7. The adjusting screws 8 can control the movement of the limiting strips 7, and the hub 1 can restrict the rotation of the limiting strips 7 during the movement of the limiting strips 7 controlled by the adjusting screws 8. A first clamping plate 9 is fixedly connected to the side of the first connecting plate 3, and a second clamping plate 10 is fixedly connected to the side of the second connecting plate 4. Both the first clamping plate 9 and the second clamping plate 10 are tightly fitted to the blade body 2. By setting the first clamping plate 9 and the second clamping plate 10, the first connecting plate 3 and the second connecting plate 4 can be connected to the blade body 2.

[0034] A connecting screw 11 is fixedly connected to the side of the first clamping plate 9 near the second clamping plate 10. The connecting screw 11 is slidably connected to the inner wall of the blade body 2. A rotating ring 12 is installed inside the second clamping plate 10, and the connecting screw 11 is threaded into the inner wall of the rotating ring 12. The first clamping plate 9 and the second clamping plate 10 can be connected through the connecting screw 11 and the rotating ring 12. The rotating ring 12 installed inside the second clamping plate 10 can rotate freely. Four limiting rods 13 are fixedly connected to the side of the rotating ring 12. All four limiting rods 13 are slidably connected to the inner wall of the second clamping plate 10. A handle 17 is fixedly connected to the side of the rotating ring 12 away from the blade body 2. The limiting rods 13 ensure a stable connection between the rotating ring 12 and the second clamping plate 10 without affecting the rotation of the rotating ring 12. The handle 17 allows for convenient control of the rotation of the rotating ring 12. Several sliding grooves are provided on the side of the first connecting plate 3 and the second connecting plate 4 near the inclined baffle 5. A slider 14 is slidably connected to the surface of each sliding groove on the first connecting plate 3 and the second connecting plate 4. The slider 14 is fixedly connected to the inclined baffle 5. A fixing rod 15 is slidably connected to the inner wall of the slider 14. A spring 16 is fixedly connected to the surface of each sliding groove on the first connecting plate 3 and the second connecting plate 4. The spring 16 is sleeved on the surface of the fixing rod 15, and the other end of the spring 16 is fixedly connected to the slider 14. The slider 14 ensures the movement and stable installation of the inclined baffle 5, and the slider 14 and spring 16 provide a buffering effect for the inclined baffle 5.

[0035] Working principle: Before installing the hub 1, first move the blade body 2 close to the hub 1 so that it is locked onto the surface of the positioning rod 6. Then rotate the adjusting screw 8 to control the limit bar 7 to move closer to the blade body 2, completing the installation of the blade body 2. After that, install the hub 1. Then move the first connecting plate 3 close to the blade body 2 so that the connecting screw 11 is locked into the inner wall of the blade body 2. Then move the second connecting plate 4 so that the second locking plate 10 moves closer to the connecting screw 11. Grasp the handle 17 and control the rotating ring 12 and the limit rod 13 to rotate on the inner wall of the second locking plate 10, completing the connection between the first locking plate 9, the connecting screw 11, and the second locking plate 10. At this time, the inclined baffle 5 is installed on the blade body 2. When using the stirring blade for stirring, the hub 1 drives the blade body 2 to rotate, thereby the blade body 2 pushes the inclined baffle 5 to rotate. At this time, the inclined baffle 5 drives the slider 14 to move in a fixed position. The sliding surface of the fixed rod 15, under the action of the spring force of the spring 16, reduces the damage caused by the friction of the slurry on the inclined baffle 5 when the hub 1 starts to rotate. Through the inclined baffle 5, the slider 14 and the spring 16, the blade body 2 can be protected as much as possible during the stirring of the grouting material by the stirring blade, thereby minimizing the damage to the blade body 2 caused by friction. At the same time, the friction damage of the inclined baffle 5 is minimized, improving the wear resistance of the blade body 2. The inclined baffle 5 can be easily replaced by the first connecting plate 3, the second connecting plate 4 and the connecting screw 11. The blade body 2 can be easily replaced by the adjusting screw 8 and the limiting strip 7. This avoids the need to replace the entire stirring blade when the inclined baffle 5 or the blade body 2 suffers severe friction damage, thus reducing the cost of use.
