Description

Technical Field

[0001] The present application relates to the technical field of mixing, and in particular to a grouting material mixer. Background Art

[0002] Grouting material mixer is a special equipment used to mix and stir grouting materials. The motor drives the mixing drum to rotate, so that the materials in the drum produce strong stirring motion driven by the blades, so as to achieve a uniform mixing effect. At the same time, the water supply system will inject an appropriate amount of water into the mixing drum as needed, and mix it with the materials to form grouting materials.

[0003] At present, grouting mixers generally use a single mixing method in the mixing process of concrete, grouting materials and other materials, that is, mainly rotating and mixing through built-in mixing blades. Although this traditional mixing method can meet basic mixing needs, in actual applications, the single mixing method often leads to uneven distribution of materials in the mixing drum and unsatisfactory mixing effects, which may affect the quality and performance of the final product. Secondly, due to the limitations of the mixing method, the mixing efficiency of the mixer is relatively low, especially when dealing with large quantities, high viscosity or high-demand materials, the mixing process may become time-consuming and inefficient.

[0036] Please combine Figure 3 and Figure 5 For reference, the aeration component is arranged on the stirring shaft 5, and the aeration component can generate certain bubbles during the stirring process, thereby improving the mixing efficiency of the materials.

[0037] Specifically, the material can be added into the mixing barrel 2 through the feeding pipe 3, and the driving motor 4 is turned on to drive the stirring shaft 5 and the stirring blades 6 to rotate, so that the material can be initially stirred and mixed.

The mixing efficiency of the material can be further improved through the gas through the aeration component.

[0038] Please continue to combine Figure 3 and Figure 4 For reference, in an exemplary embodiment, the support assembly includes a support sleeve 7, a guide ring plate 8, and a support plate 9, wherein the support sleeve 7 is fixedly mounted on the inner bottom surface of the mixing barrel 2, and the support sleeve 7 is coaxially arranged with the mixing barrel 2; the guide ring plate 8 is slidably mounted in the support sleeve 7; the support plate 9 is fixedly mounted on one end of the guide ring plate 8 away from the support sleeve 7, and the end of the mixing shaft 5 away from the driving motor 4 passes through the support plate 9, and the support plate 9 is movably connected with the mixing shaft 5.

[0039] In one embodiment, a discharge pipe 24 is provided through the bottom of the mixing barrel 2 , and the lowest position of the discharge pipe 24 is flush with the highest position of the support plate 9 .

[0040] Furthermore, control valves are installed in both the feeding pipe 3 and the discharging pipe 24 .

[0041] Specifically, the support sleeve 7 is fixed to the inner bottom surface of the mixing barrel 2. When in use, the guide ring plate 8 can slide back and forth in the support sleeve 7 to drive the support plate 9 to slide back and forth, thereby vibrating the material above the support plate 9 to further fully stir the material in the mixing barrel 2.

[0042] Please continue to combine Figure 4 For reference, in an exemplary embodiment, the adjustment component includes an annular groove 10, a transmission ring plate 11, a plurality of teeth 12, a plurality of rotating rods 13, a plurality of vertical plates 14, a plurality of teeth 2 15, and a plurality of levers 23, wherein the annular groove 10 is provided on the inner bottom surface of the mixing barrel 2, and the annular groove 10 is adapted to the supporting sleeve 7; the transmission ring plate 11 is rotatably mounted in the annular groove 10; a plurality of teeth 12 are distributed in an annular array and fixedly mounted on the end of the transmission ring plate 11 away from the annular groove 10; a plurality of rotating rods 13 are distributed in an annular array and rotatably mounted in the annular groove 10; a plurality of vertical plates 14 are respectively fixedly mounted on the plurality of rotating rods 13; a plurality of teeth 2 15 are all distributed in an annular array and fixedly mounted on the rotating rod 13, and the teeth 2 15 are meshed with the teeth 12; a plurality of levers 23 are distributed in an annular array and fixedly mounted on the end of the guide ring plate 8 away from the support plate 9.

[0043] In one embodiment, one end of the lever 23 away from the guide ring plate 8 is configured to be hemispherical.

[0044] Specifically, the support plate 9 is movably connected to the stirring shaft 5, so that the support plate 9 can slide along the stirring shaft 5 and rotate with the stirring shaft 5. When the support plate 9 rotates with the stirring shaft 5, the lever 23 on the bottom guide ring plate 8 can contact the vertical plate 14 in the annular groove 10, and under the action of the vertical plate 14, the lever 23 can slide along the vertical plate 14 through the hemispherical design, thereby driving the guide ring plate 8 to slide in the support sleeve 7, thereby realizing the vibration of the guide ring plate 8 and the support plate 9.

[0045] Please continue to combine Figure 2 and Figure 3 For reference, in an exemplary embodiment, the driving assembly includes a guide opening 16, a lap plate 17, and an electric push rod 18, wherein the guide opening 16 is opened at the end of the mixing barrel 2 away from the driving motor 4, and the guide opening 16 is connected to the annular groove 10; the lap plate 17 is fixedly installed at the end of the transmission ring plate 11 away from the tooth 2 15, and the end of the lap plate 17 away from the transmission ring plate 11 passes through the guide opening 16; the electric push rod 18 is rotatably installed at the end of the mixing barrel 2 away from the driving motor 4, and the telescopic end of the electric push rod 18 is rotatably connected to the lap plate 17.

[0046] Specifically, when adjusting the inclination angle of the vertical plate 14, the electric push rod 18 can be opened, and the two ends of the electric push rod 18 are rotatably connected to the mixing barrel 2 and the lap plate 17 respectively. Therefore, when the electric push rod 18 is opened, the lap plate 17 can be driven to slide along the guide port 16, thereby driving the transmission ring plate 11 to rotate, and the tooth 12 is engaged with the tooth 2 15. Therefore, when the transmission ring plate 11 rotates, the tooth 12 and the tooth 2 15 can drive the rotating rod 13 and the vertical plate 14 to rotate to achieve the adjustment of the inclination angle, and after the adjustment is completed, the electric push rod 18 is fixed to fix the angle of the vertical plate 14. By adjusting the angle of the vertical plate 14, the support plate 9 can vibrate with different amplitudes to adapt to different materials for use.

[0047] Please continue to combine Figure 3 and Figure 5 For reference, in an exemplary embodiment, the aeration assembly includes a sealing shell 19, a piston plate 20, a plurality of air pipes 21, a conduit 27, a plurality of one-way valves 22, and a guide mechanism, wherein the sealing shell 19 is fixedly installed in the mixing barrel 2 by a bracket, and the sealing shell 19 is sleeved on the outer wall of the mixing shaft 5; the piston plate 20 is slidably installed in the sealing shell 19; a plurality of air pipes 21 are distributed in a linear array and are arranged on the sealing shell 19; the conduit 27 is arranged on the sealing shell 19, and the end of the conduit 27 away from the sealing shell 19 passes through the mixing barrel 2 and is connected to the outside; a plurality of one-way valves 22 are respectively installed in a plurality of air pipes 21 and the conduit 27; and the guide mechanism is arranged between the sealing shell 19 and the piston plate 20.

[0048] Specifically, when the stirring shaft 5 rotates, the piston plate 20 can be driven to slide back and forth in the sealing shell 19 through the guide mechanism. Under the action of two sets of one-way valves 22 with opposite flow directions, when the piston plate 20 moves upward, negative pressure is formed in the sealing shell 19 and air can be sucked in along the conduit 27. When the piston plate 20 moves downward, the gas in the sealing shell 19 can be pressed out and discharged along the air pipe 21 to impact and mix the materials.

[0049] like Figure 5 As shown, the guide mechanism includes a slide groove 25 and a slider 26 , wherein the slide groove 25 is provided in the sealing shell 19 ; the slider 26 is fixedly mounted on the piston plate 20 , and the slider 26 is slidably connected to the slide groove 25 .

[0050] Specifically, during the sliding of the piston plate 20 , the slider 26 can slide in the slide groove 25 to guide the piston plate 20 , thereby ensuring that the piston plate 20 can slide stably.

[0051] In one embodiment, the stirring shaft 5 is provided with trapezoidal threads screwed to the piston plate 20 at the upper and lower sides of the piston plate 20 .

[0052] It can be understood that the trapezoidal threads on the stirring shaft 5 can form a reciprocating screw at a section of the stirring shaft 5 located on both sides of the piston plate 20, so as to drive the piston plate 20 to slide back and forth when rotating.

[0053] The grouting material mixer proposed in the embodiment of the present application adopts the sliding of the guide ring plate 8 in the supporting sleeve 7 to realize the reciprocating vibration of the support plate 9. This structure is simple and easy to implement, and can effectively convert the rotational motion into the vibration motion, thereby improving the energy conversion efficiency. The reciprocating motion of the piston plate 20 in the sealing shell 19 is driven by the rotation of the stirring shaft 5. Combined with the action of the one-way valve 22, intermittent aeration and mixing of the material is realized, and the mixing effect is further improved. The inclination angle of the vertical plate 14 is adjusted by the electric push rod 18, thereby controlling the vibration amplitude of the support plate 9, which can adapt to the mixing requirements of different materials and improve the flexibility and applicability of the equipment.

[0054] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
