The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent after understanding the disclosure of this application. Throughout this specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. Conversely, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between. As used herein, the term "and / or" includes any one of the relevant items listed and any combination of any two or more of them. Although terms such as "first," "second," and "third" may be used herein to describe individual components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. More precisely, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as such in the examples may also be referred to as the second component, assembly, region, layer, or part. For ease of description, spatial relational terms such as “above,” “upper,” “below,” and “lower” may be used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relational terms are intended to include not only the orientation depicted in the drawings but also the different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element.Therefore, the term "above" includes both "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly. The terminology used herein is for describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "comprising," "including," and "having" enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof. Variations in the shapes shown in the figures may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the figures but include changes in shape that occur during manufacturing. The features of the examples described herein may be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible as will be apparent upon understanding the disclosure of this application.

[0045] like Figures 1-3 As shown, this embodiment provides a grouting mixing device with replaceable mixing paddles, including a mixing tank 1, a motor fixing plate 3, a motor 5, a connector 8, and multiple mixing paddles 6;

[0046] One end of the motor fixing plate 3 is connected to the mixing tank 1 via a rotating shaft assembly 4, allowing the motor fixing plate 3 to rotate relative to the mixing tank 1; the upper surface of the other end of the motor fixing plate 3 is equipped with a motor 5, and the lower surface is provided with a connector 8; the motor 5 and the connector 8 are connected by a transmission device.

[0047] Multiple agitators 6 have the same end and can be detachably connected to connectors 8 respectively.

[0048] The stirring paddle 6 includes a stirring rod 61, with blades 62 at the lower part and a threaded section 63 at the upper part.

[0049] The connector 8 and the agitator 6 can be connected by a thread, which is simple and convenient to disassemble and assemble, and easy to operate.

[0050] This embodiment also provides a preferred implementation method, such as... Figure 9 As shown, a through hole 65 is provided at the upper part of the stirring paddle 6 near the top, and two opposing elongated holes 81 are provided on the connector 8; after the stirring paddle 6 and the connector 8 are tightened together, the through hole 65 and the elongated holes 81 are opposite each other; the fixing bolt 82 can pass through the elongated holes 81 and the through hole 65 to fix the stirring paddle 6 and the connector 8 together.

[0051] This connection method effectively prevents circumferential displacement between the stirring paddle 6 and the connector 8 during high-speed rotation, thereby ensuring the safety and reliability of the stirring process.

[0052] An auxiliary box 2 is installed on the outer wall of the mixing tank 1, and a rotating shaft assembly 4 is installed on the top surface of the auxiliary box 2. One end of the motor fixing plate 3 is rotatably connected to the auxiliary box 2 through the rotating shaft assembly 4.

[0053] Furthermore, a limit stop (not shown in the figure) is provided on the rotating shaft assembly 2 to limit the rotation angle of the rotating shaft assembly, thereby limiting the position of the motor fixing plate 3 when it is raised and lowered.

[0054] When replacing the agitator 6, raise the motor mounting plate 3 to its highest point to fully expose the connection between the agitator 6 and the connector 8, and then you can replace the agitator 6.

[0055] To ensure safety when replacing the mixing paddle 6, it is necessary to position the motor mounting plate 3 when it is lifted to prevent it from falling.

[0056] like Figure 8 As shown, this embodiment provides a method for positioning the rotating shaft assembly 2. Specifically, an insertion hole 21 is provided at the upper part of the auxiliary box 2, and a pin 22 is provided above the insertion hole 21. The pin 22 is installed on the wall of the auxiliary box 2 and can slide up and down. A connecting plate 41 is provided above the rotating shaft of the rotating shaft assembly 4, and an adjusting plate 42 bent into an arc shape is connected to the outer end of the connecting plate 41. The adjusting plate 42 extends into the insertion hole 21, and multiple fixing holes are provided on the adjusting plate 42 at intervals.

[0057] When the motor mounting plate 3 rotates, the adjusting plate 42 also rotates accordingly; when it reaches the preset position, the pin 22 is inserted into the fixing hole of the adjusting plate 42 to fix the motor mounting plate 3.

[0058] In an alternative solution, a hook can be provided at the outer end of the connecting plate 41; a hanging groove can be provided on the upper wall of the auxiliary box 2; when the motor fixing plate 3 is flipped upward to the maximum angle, the hook can be hooked into the hanging groove, thereby keeping the motor fixing plate 3 in the raised state.

[0059] The agitator 6 includes Figure 4 and Figure 5 The screw-type agitator shown is suitable for grouting materials containing fibers (steel fibers, polypropylene fibers) and colloids (thixotropic agents) due to its "low-speed horizontal circulation and high-speed radial flow" characteristics. The order of material addition is: water first, then admixtures (steel fibers, polypropylene fibers, etc.), and finally the cementitious material. Using this type of agitator can prevent the addition of fiber admixtures from being interrupted during rapid mixing.

[0060] by Figure 5 Taking the screw-type agitator as an example, it includes an agitator 61, a thickened section 64 disposed at the lower end of the agitator 61, and a threaded section 63 disposed at the upper end of the agitator 61; a blade 62 is disposed on the outside of the thickened section 64.

[0061] The diameter of the stirring rod 61 is d, the diameter of the thickened section 64 is 1.5d~1.8d, preferably 1.6d; the diameter of the spiral is 3d~3.5d, preferably 3.3d; the pitch is 0.8d~1d, preferably 0.9d; the helix angle is 25°~35°, preferably 30°; and the propeller blades have 4-6 rings.

[0062] Also includes Figure 6 The mesh agitator shown features a multi-strand annular design, providing a large mixing area and strong shearing force. It effectively breaks up material lumps, making it particularly suitable for mixing medium-to-high viscosity grouting materials containing water glass.

[0063] Also includes Figure 7 The propeller-type agitator shown, based on its fluid characteristics of "high-speed, strong axial flow, and full-depth circulation," has inclined blades at an angle of 30-45 degrees. When rotating at high speed (≥200 rpm), it generates a strong axial flow, but its radial dispersion ability is weak. It is suitable for mixing cement slurry with added lightweight aggregates or accelerators. The high-speed axial flow can cause the thick slurry at the bottom of the bucket to surge upwards, breaking up stratification / sedimentation caused by density differences between the top and bottom, and avoiding the situation of "sedimentation at the bottom and thin slurry at the top" caused by the action of lightweight aggregates or accelerators.

[0064] It can also be equipped with ribbon agitators and other forms, which will not be described in detail here.

[0065] In other embodiments, the bottom of the mixing tank 1 is also provided with at least three wheels 7 arranged in two rows, front and back. At least one of the rows of wheels 7 is a caster wheel, thereby allowing the mixing device to move freely.

[0066] This application allows for the replacement of the mixing blades according to the characteristics and technical requirements of the grouting material. The mixing blades are available in various shapes and materials; for example, for high-viscosity grouting materials, blades of a specific shape can be selected to enhance the mixing effect, while for materials with larger particles, blades made of wear-resistant materials are available. Furthermore, blade replacement is convenient and quick, effectively reducing downtime. This device improves construction efficiency, reduces costs, and possesses high structural safety and reliability.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
