[0002] Cement-based grouting material is a powdered material premixed in appropriate proportions at the factory, consisting of a high-strength binder, a super-inking component, an expansive component, a preferably graded aggregate component, and a trace amount of a modified component. Simply adding water and stirring creates a uniform, self-leveling, high-strength, non-shrinkage grouting material that meets construction requirements and has the desired consistency. The quality of the mixture determines the quality of the grouting.

[0004] In the above solution, after inserting the stirring blade at the top of the stirring rod into the feed frame, it is necessary to insert a pin to fasten the two together. Before inserting the pin, it is necessary to align the stirring blade with the hole in the feed frame. Therefore, the entire fastening process has many steps and is relatively cumbersome. In addition, it is time-consuming for the staff to insert the stirring blade into the feed frame and align the stirring blade with the hole in the feed frame, which requires the staff to hold the stirring rod tightly for a long time. Holding the stirring rod tightly for a long time increases the staff's workload, which has certain limitations in actual use. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0029] Example 1: Figure 1-Figure 5 As shown, the technical solution adopted by the present invention is as follows: a cement-based grouting material mixing device includes a main body 1, a handle 6 is fixedly installed on the top of the main body 1, and a plurality of wheels are rotatably provided on the bottom of the main body 1.

[0030] A vertical support frame 2 is fixed on the top of the main body 1. The top of the support frame 2 is tilted at an angle of 3-15 degrees. A circular rotating base 4 is rotatably set on the top of the support frame 2. The rotating base 4 has the same tilt angle as the top of the support frame 2. An arc-shaped limit frame is fixed on the top of the rotating base 4. A binding belt 5 is slidingly provided inside the limit frame. The two ends of the binding belt 5 slide out from the two ends of the limit frame and are connected end to end through a tensioner. The binding belt 5, the tensioner, and the connection method between the binding belt 5 and the tensioner are all existing technologies and will not be described in detail in this solution.

[0031] A mixing drum 3 is placed on top of the rotating base 4. A stirring element is provided within the mixing drum 3, which is positioned within the space enclosed by a retaining frame and a binding strap 5. The mixing drum 3 is tilted, with the bottom of the mixing drum 3 in contact with the top of the rotating base 4. The binding strap 5 is tightened by a tensioner, thereby limiting the position of the mixing drum 3. A first motor 23 is fixedly mounted on the support frame 2. The output shaft of the first motor 23 rotates through the support frame 2 and is coaxially fixedly connected to the bottom of the rotating base 4.

[0032] The output shaft of the first motor 23 drives the rotating base 4 to rotate, and the rotating base 4 drives the mixing barrel 3 to rotate, thereby performing the mixing work. In addition, the tilted mixing barrel 3 can improve the collision effect between the grouting material and the stirring member, thereby improving the overall stirring effect.

[0033] A vertical plate 13 is fixed on the top of the main body 1, and an adjustment mechanism is provided on the vertical plate 13. The adjustment mechanism is provided with a clamping assembly. The clamping assembly is used to clamp and limit the stirring piece. The adjustment mechanism can adjust the position of the stirring piece in the mixing barrel 3 through the clamping assembly.

[0034] The adjustment mechanism includes a fixed frame 12, a horizontal fixed frame 12 is fixed on the top of the vertical plate 13, and a first screw rod 18 is rotatably arranged in the fixed frame 12. One end of the first screw rod 18 is rotatably connected to the fixed frame 12, and the other end rotates in turn through the fixed frame 12 and the vertical plate 13 and is coaxially fixed with a turntable 14. A handle is eccentrically arranged on the side of the turntable 14 that is not connected to the first screw rod 18. In addition, a first slide groove 16 is provided in the horizontal direction in the fixed frame 12, and a slider 17 is provided in the first slide groove 16 to slide in the horizontal direction. The slider 17 is threadedly connected to the first screw rod 18. Two support columns 15 are fixedly arranged in the horizontal direction on the side of the slider 17 away from the turntable 14. The ends of the two support columns 15 that are not connected to the slider 17 slide through the fixed frame 12 and are fixedly connected to the clamping assembly.

[0035] Two limiting rings are fixedly provided on the outer surface of each support column 15. One limiting ring on the same support column 15 is located inside the fixing frame 12, and the other limiting ring is located outside the fixing frame 12. These limiting rings are used to limit the movement of the clamping assembly and prevent the clamping assembly from colliding with the inner wall of the mixing drum 3 during movement.

[0036] Rotating the handle can drive the first screw rod 18 to rotate, and the rotation of the first screw rod 18 will drive the slider 17 to slide, thereby pushing the clamping assembly through the support column 15, and then adjusting the position of the clamping assembly.

[0037] The clamping assembly includes a first support plate 11, and one end of the two support columns 15 not connected to the turntable 14 is fixedly connected to the same first support plate 11. The first support plate 11 is provided with both a second slide groove 22 and a groove 21. A sliding rod 20 is fixedly arranged horizontally in the second slide groove 22, and two clamping plates 9 are slidingly arranged on the outer surface of the sliding rod 20. Both clamping plates 9 are limitedly slidably arranged in the second slide groove 22. The two clamping plates 9 are arranged facing each other and symmetrically. The opposite sides of the two clamping plates 9 are fixedly connected to the inner wall of the second slide groove 22 by elastic members. A spring 19 is fixedly arranged on the opposite sides of the two clamping plates 9. Both springs 19 are sleeved on the outer surface of the sliding rod 20. The ends of the two springs 19 not connected to the clamping plates 9 are fixedly connected to the inner wall of the second slide groove 22.

[0038] The facing sides of the two clamping plates 9 are all fixedly provided with a plurality of limit blocks, and the limit blocks are set in a smooth arc shape. One end of the two clamping plates 9 away from the slide bar 20 is all inclined, and the two clamping plates 9 present an "eight" shape.

[0039] In addition, a T-shaped block is fixedly provided at the bottom of each of the two clamping plates 9. Two T-shaped slots are provided on the first support plate 11, and the T-shaped blocks and the T-shaped slots are respectively corresponding and slidingly engaged. The arrangement of the T-shaped blocks and the T-shaped slots makes the clamping plates 9 more stable when sliding.

[0040] The stirring element includes a fixed block 10, one end of which is inclined and slides with the inclined ends of the two clamping plates 9. A spring 19 can clamp and restrict the fixed block 10. A number of limiting grooves are provided on both sides of the fixed block 10. The number of limiting grooves is equal to the number of limiting blocks and they correspond one to one. Each limiting groove is engaged with a corresponding limiting block.

[0041] A stirring block 8 is fixedly mounted at the bottom of the fixed block 10. The stirring block 8 slides within the groove 21 to prevent the stirring block 8 from rotating within the groove 21. A stirring frame is fixedly mounted at the bottom of the stirring block 8. The stirring frame is located within the stirring barrel 3 and has a plurality of stirring blades 7 fixed thereto. The stirring blades 7 are arranged at an irregular angle.

[0042] The tilted arrangement of the fixing block 10 and the two clamping plates 9 facilitates insertion of the fixing block 10 between the two clamping plates 9. Once the fixing block 10 is inserted between the two clamping plates 9, the stop block engages within the stop slot, thereby securing the fixing block 10 and preventing it from sliding. Furthermore, during insertion, the fixing block 10 compresses the spring 19, further securing the fixing block 10 using its elasticity, preventing it from separating from the clamping plates 9 during collision between the grouting material and the mixing frame.

[0043] Working Principle of Example 1: During use, an empty mixing drum 3 is placed on a rotating base 4 and secured by tightening the binding strap 5 with a tensioner. The mixing frame is then placed inside the mixing drum 3, and the fixing block 10 is pushed toward the clamping plates 9. As the fixing block 10 moves, the mixing block 8 slides within the groove 21, and the inclined end of the fixing block 10 contacts the inclined ends of the two clamping plates 9.

[0044] After the fixing block 10 contacts the two clamping plates 9, it will push the two clamping plates 9 away from each other under the guidance of the slide rod 20 and the T-shaped block. In the process of the two clamping plates 9 moving away from each other, the spring 19 will be squeezed, causing the compression deformation of the spring 19 to gradually increase.

[0045] When the fixed block 10 passes through the inclined part of the two clamps 9, the compression deformation of the spring 19 gradually tends to be stable. As the pushing continues, the limit blocks on the opposite sides of the two clamps 9 will slide and cooperate with the limit grooves on both sides of the fixed block 10, causing the two clamps 9 to repeatedly change their own motion state, so that the two clamps 9 are repeatedly adjusted in the motion state of moving away from and approaching each other, and the deformation of the spring 19 will also be slightly adjusted as the connection relationship between the limit blocks and the limit grooves changes. When the fixed block 10 contacts the first support plate 11, all the limit blocks are just stuck in the corresponding limit grooves, thereby completing the limit of the fixed block 10 by the limit blocks, and then completing the limit of the stirring member by the limit assembly.

[0046] After the stirring element is positioned, mixing water is added to the mixing barrel 3 and the first motor 23 is started. The output shaft of the first motor 23 drives the mixing barrel 3 to rotate via the rotating base 4. At this point, the worker slowly adds cement-based grout along the barrel wall. The cement-based grout and water rotate with the mixing barrel 3, colliding with the stirring blades 7, thereby breaking up the grout and mixing it with the water.

[0047] In addition, when the first motor 23 is started, the turntable 14 can be rotated at the same time. The rotation of the turntable 14 drives the first screw 18 to rotate. The rotation of the first screw 18 drives the slider 17 to slide along the central axis of the first screw 18 in the first chute 16. The sliding of the slider 17 drives the mixing frame to slide synchronously through the support column 15, thereby improving the overall mixing effect. During this process, the support column 15 can be limited by the provision of a limit ring, thereby preventing the mixing frame from colliding with the inner wall of the mixing barrel 3.

[0048] After stirring evenly, turn off the first motor 23 and pull the fixing block 10 to separate the fixing block 10 from the clamping plate 9. Then pull the stirring block 8 upward to remove the stirring blade 7. Then loosen the binding belt 5 and lift the stirring barrel 3 upward.

[0049] Example 2: Figure 6-Figure 7As shown, the difference between the second embodiment and the first embodiment is that the second embodiment is provided with a driving mechanism for adjusting the height of the adjusting mechanism, and the driving mechanism can also start the adjusting mechanism during the process of adjusting the height of the adjusting mechanism.

[0050] The drive mechanism includes a gear 27. A third slot 28 is defined in the upper portion of the riser 13. Two second screw rods 24 are vertically rotatably mounted within the third slot 28. Both second screw rods 24 are threadedly connected to the fixed frame 12. Two second motors 25 are fixedly mounted on the top of the riser 13. The output shafts of both second motors 25 rotate and extend into the third slot 28. The output shafts of the second motors 25 are fixedly connected to the second screw rods 24 in a one-to-one correspondence. The bottoms of the two second screw rods 24 are rotatably connected to the inner wall of the third slot 28.

[0051] The end of the first screw rod 18 away from the clamping assembly rotates in sequence to pass through the fixed frame 12 and the vertical plate 13 and is coaxially fixedly connected to the gear 27. A vertical rack 26 is fixed on the outer surface of the vertical plate 13, and the rack 26 is engaged with the gear 27 for transmission.

[0052] Working Principle of Example 2: When in use, the second motor 25 is started, and the output shaft of the second motor 25 drives the second screw 24 to rotate, thereby driving the fixed frame 12 to move in the vertical direction. The movement of the fixed frame 12 drives the mixing frame and the mixing blade 7 to move in the vertical direction within the mixing barrel 3. At the same time, through the engagement of the gear 27 and the rack 26, the fixed frame 12 drives the gear 27 to rotate during the vertical movement. The gear 27 drives the first screw 18 to rotate, thereby driving the mixing frame and the mixing blade 7 to move in the horizontal direction, thereby improving the overall mixing efficiency.
