[0003] For example, an energy-saving and environment-friendly vertical concrete mixer disclosed in the national patent publication number CN115229982B includes a mixing barrel and a mixing shaft rotatably arranged in the mixing barrel.

The reciprocating pipe is inclined towards the bottom wall of the mixing barrel and arranged on the mixing barrel. A spiral conveyor shaft is rotatably arranged in the reciprocating pipe. The rotation axis of the spiral conveyor shaft is coaxially arranged with the reciprocating pipe. A first notch for concrete to enter the reciprocating pipe is opened on the reciprocating pipe.

[0030] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] Example 1, please refer to Figures 1 to 9, the present invention provides a technical solution: a material mixing device for building construction projects, including a mixer barrel 1. A barrel holder 2 is fixedly connected to the bottom outer wall of the mixer barrel 1. A first reciprocating motor 3 is fixedly installed at the axial center position of the bottom outer wall of the mixer barrel 1. A through hole communicating with the inner wall is opened on the bottom outer wall of the mixer barrel 1. The outer wall of the shaft of the first reciprocating motor 3 is rotationally connected to the inner wall of the through hole. The shaft of the first reciprocating motor 3 is fixedly connected with an inner rotating shaft 5 through the through hole. A spiral feeding frame 6 is fixedly wound around the outer wall of the inner rotating shaft 5. An outer transmission barrel 4 is fixedly connected to the bottom inner wall of the mixer barrel 1. The inner wall of the outer transmission barrel 4 is movably connected to the outer wall of the spiral feeding frame 6. The spiral feeding frame 6 is provided with a plurality of feeding and mixing holes 26 that communicate with the upper and lower outer walls. The feeding and mixing holes 26 are evenly distributed in an array along the circumference of the spiral feeding frame 6. A plurality of flow channels 11 are opened on the outer walls around the bottom of the outer transmission barrel 4. The plurality of flow channels 11 are evenly distributed in an array. An outlet 17 is opened on the top outer wall of the outer transmission barrel 4.

[0032] In the present invention, by starting the first reciprocating motor 3 to drive the inner rotating shaft 5 to rotate, the spiral feeding frame 6 is driven to rotate synchronously by the inner rotating shaft 5. When the staff adds the materials to be mixed into the mixer barrel 1, the bottom of the cavity of the mixer barrel 1 is filled. At this time, the materials will flow into the bottom of the outer transmission barrel 4 through the flow channels 11 under pressure. The rotation of the spiral feeding frame 6 will scoop up the materials at the bottom of the outer transmission barrel 4, and thus generate a siphon effect, so that more materials are conveyed upward with the rotation of the spiral feeding frame 6 and flow out from the outlet 17 on the top side of the outer transmission barrel 4. Through this device, the materials that are difficult to stir at the bottom of the mixer barrel 1 can be first mixed by the rotation of the spiral feeding frame 6, and the materials at the bottom of the mixer barrel 1 are conveyed to the upper surface of the mixer barrel 1 by the rotation of the spiral feeding frame 6, and the upper layer of materials will sink synchronously, so as to completely mix the upper and lower layers of materials in a large cycle, thereby improving the mixing effect of the present invention.

[0033] Furthermore, in the present invention, by opening a plurality of feeding and mixing holes 26 in the spiral feeding frame 6, when the mixed materials in the outer transmission barrel 4 are conveyed upward, part of the materials will be squeezed by gravity and flow through the feeding and mixing holes 26 into the lower space. Through this device, part of the materials in each layer in the outer transmission barrel 4 are mixed with the lower layer of materials, providing a small cycle on the basis of the large cycle of the outer transmission barrel 4 to achieve the second mixing, thereby further realizing the complete mixing of the present invention and improving the mixing effect of the present invention.

[0034] Embodiment 2. On the basis of Embodiment 1, a central axis holding beam 7 is provided at the top of the inner rotating shaft 5. The position of the axis of the bottom outer wall of the central axis holding beam 7 is fixedly connected to the top outer wall of the inner rotating shaft 5. Mixing connecting rods 8 are fixedly connected to the bottoms of the outer walls at both ends of the central axis holding beam 7. A positioning connecting plate 9 is fixedly connected to the bottom outer wall of the mixing connecting rod 8. A plurality of adjusting scraping plates 10 are fixedly connected to the bottom outer wall of the positioning connecting plate 9. The plurality of adjusting scraping plates 10 are installed at an inclination of 45° with the outer transmission cylinder 4 as the axis. The height of the adjusting scraping plate 10 is flush with the height of the circulation channel 11. A pressure relief channel 27 communicating with the front and rear sides is opened on the bottom outer wall of the adjusting scraping plate 10. A rubber gasket 28 is fixedly connected to the bottom outer wall of the adjusting scraping plate 10. The bottom outer wall of the rubber gasket 28 is movably attached to the bottom inner wall of the mixer barrel 1. A plurality of inclined plates 12 are fixedly connected to the outer wall of the mixing connecting rod 8. The plurality of inclined plates 12 are all installed at an inclination of 45°.

[0035] In the present invention, the rotation of the inner rotating shaft 5 drives the mixing connecting rod 8 and the inclined plate 12 to rotate, so as to mix and stir the materials in the mixer barrel 1 to achieve the third mixing. At the same time, the mixing connecting rod 8 drives the adjusting scraping plate 10 to rotate synchronously. By using the 45° inclination installation of the plurality of adjusting scraping plates 10, while achieving the fourth mixing, the materials at the bottom layer in the mixer barrel 1 can be gradually converged towards the center point by rotation. Through this device, the materials at the bottom layer in the mixer barrel 1 are pushed into the circulation channel 11 and circulated to the surface layer. At the same time, some of the materials when the adjusting scraping plate 10 squeezes the materials will be squeezed out through the pressure relief channel 27, avoiding excessive pressure and further mixing to achieve the fifth mixing.

[0036] Embodiment 3. On the basis of Embodiment 1, a first plastic folding tube 13 is fixedly connected to the top outer wall of the outer transmission cylinder 4. A connecting collar 14 is fixedly connected to the top outer wall of the first plastic folding tube 13. A conical ring plate 15 is provided on the top outer wall of the connecting collar 14. The conical ring plate 15 is conical, with a narrow top and a wide bottom. A plurality of circulation holes 16 are opened on the outer wall of the conical ring plate 15. The circulation holes 16 are evenly distributed in an array.

[0037] In the present invention, the mixed materials discharged from the outer transmission cylinder 4 to the discharge port 17 will flow layer by layer on the outer surface of the conical ring plate 15 with the discharge undulation generated by the rotation of the spiral feeding rack 6 and spread and drip outwards along the slope. While the materials spread and flow, the mixed materials gradually drip onto the upper layer of the materials in the mixer barrel 1 through the circulation holes 16. Through this device, the relative fixation of the discharge position is avoided, thereby avoiding the stacking effect, achieving the sixth mixing, making the mixing of the materials more uniform, and further achieving complete mixing in time, improving the mixing effect of the present invention.

[0038] Embodiment 4. On the basis of Embodiment 2, a second reciprocating rotation motor 18 is fixedly installed on the outer wall of the top of the central axis holding beam 7. A through hole communicating with the upper and lower ends is provided in the central axis holding beam 7. The axis of the second reciprocating rotation motor 18 is fixedly connected to a resilient spring connecting shaft 21. A rotating shaft rod 22 is fixedly connected to the outer wall of the bottom of the resilient spring connecting shaft 21. A polarization stator 23 is fixedly connected to the outer wall of one side of the rotating shaft rod 22. A second plastic folding tube 19 is fixedly connected to the outer wall of the bottom of the second reciprocating rotation motor 18. The outer wall of the second plastic folding tube 19 is fitted with the inner wall of the through hole. An outer protective sleeve 20 is fixedly connected to the outer wall of the bottom of the second plastic folding tube 19. Two connecting hinges 24 are provided on the inner wall of the outer protective sleeve 20. The outer sleeves of the two connecting hinges 24 are respectively fixedly connected to the inner walls of the upper and lower ends of the outer protective sleeve 20. The inner sleeves of the two connecting hinges 24 are respectively fixedly connected to the outer walls of the upper and lower ends of the rotating shaft rod 22. A rubber contact head 25 is fixedly installed on the outer wall of the bottom of the outer protective sleeve 20. The outer wall of the bottom of the rubber contact head 25 is pressed and fitted with the upper surface of the conical ring plate 15. The outer wall of the conical ring plate 15 is inclined under the pressing of the rubber contact head 25.

[0039] In the present invention, by starting the second reciprocating rotation motor 18 to drive the resilient spring connecting shaft 21 to rotate, further driving the rotating shaft rod 22 and the polarization stator 23 to rotate, the rotation of the polarization stator 23 drives the rubber contact head 25 to generate high-frequency polarization. The polarization effect of the polarization stator 23 is realized through the resilient characteristics of the resilient spring connecting shaft 21 and the second plastic folding tube 19. The rubber contact head 25 uses this polarization effect to high-frequency vibrate the outer wall of one side of the conical ring plate 15, thereby achieving three effects: 1. Vibration accelerates the flow rate of the material on the conical ring plate 15 and avoids material accumulation; 2. Through this vibration, mild mixing of the material on the conical ring plate 15 is realized, and the mixing density of the material is increased to achieve the seventh mixing; 3. Through this vibration, blockage of the through holes 16 on the conical ring plate 15 can be effectively avoided, so as not to affect the dripping effect of the mixed material; at the same time, the rotation of the central axis holding beam 7 drives the rubber contact head 25 to continuously rotate on the outer surface wall of the conical ring plate 15, ensuring the mixing uniformity rate of the material on the conical ring plate 15.

[0040] Working principle and usage process of the present invention: In the present invention, starting the first reciprocating motor 3 drives the inner rotating shaft 5 to rotate, and the inner rotating shaft 5 drives the spiral feeding rack 6 to rotate synchronously. After the staff adds the materials to be mixed into the mixing barrel 1 of the mixer, the bottom of the cavity of the mixing barrel 1 is filled. At this time, the materials will flow into the bottom of the outer transmission cylinder 4 through the circulation channel 11 under pressure. The rotation of the spiral feeding rack 6 will scoop up the materials at the bottom of the outer transmission cylinder 4, and thus generate a siphon effect, causing more materials to be conveyed upward with the rotation of the spiral feeding rack 6 and flowing out from the discharge port 17 on the top side of the outer transmission cylinder 4. Through this device, the materials that are difficult to stir at the bottom of the mixing barrel 1 of the mixer can be first mixed through the rotation of the spiral feeding rack 6, and the materials at the bottom of the mixing barrel 1 of the mixer can be conveyed to the upper surface of the mixing barrel 1 through the rotation of the spiral feeding rack 6, and the upper-layer materials will sink synchronously, so as to completely mix the upper and lower-layer materials in a large cycle, thereby improving the mixing effect of the present invention. Further, in the present invention, by opening a plurality of feeding and mixing holes 26 in the spiral feeding rack 6, when the mixed materials in the outer transmission cylinder 4 are conveyed upward, part of the materials will be squeezed by gravity and flow into the lower-layer space through the feeding and mixing holes 26. Through this device, part of the materials in each layer in the outer transmission cylinder 4 are mixed with the lower-layer materials, providing a small cycle on the basis of the large cycle of the outer transmission cylinder 4 to achieve secondary mixing, thereby further realizing the complete mixing of the present invention and improving the mixing effect of the present invention.In the present invention, the rotation of the inner rotating shaft 5 drives the mixing connecting rod 8 and the inclined plate 12 to rotate, so as to mix and stir the materials in the mixing barrel 1 of the mixer, realizing the third mixing. At the same time, the mixing connecting rod 8 drives the adjusting scraper 10 to rotate synchronously. By the 45° inclined installation of a plurality of adjusting scrapers 10, while realizing the fourth mixing, the materials at the bottom layer in the mixing barrel 1 of the mixer can be gradually converged towards the center point by rotation. Through this device, the materials at the bottom layer in the mixing barrel 1 of the mixer are pushed into the circulation channel 11 and circulated and conveyed to the surface layer. At the same time, some of the materials when the adjusting scraper 10 squeezes the materials will be squeezed out through the pressure relief channel 27, avoiding excessive pressure and further mixing, realizing the fifth mixing. In the present invention, the mixed materials discharged from the outer transmission cylinder 4 to the discharge port 17 will flow layer by layer on the outer surface of the conical ring plate 15 with the discharging undulation generated by the rotation of the spiral feeding rack 6 and diffuse and drip outwards along the slope. While the materials diffuse and flow, the mixed materials gradually drip onto the upper layer of the materials in the mixing barrel 1 of the mixer through the circulation holes 16. Through this device, the relative fixation of the discharging position is avoided, thereby avoiding the stacking effect, realizing the sixth mixing, making the mixing of the materials more uniform, and further realizing complete mixing in time, improving the mixing effect of the present invention. In the present invention, by starting the second reciprocating rotating motor 18 to drive the resilient spring connecting shaft 21 to rotate, further driving the rotating shaft rod 22 and the polarized stator 23 to rotate. The rotation of the polarized stator 23 drives the rubber contact head 25 to generate high-frequency polarization. Through the resilient characteristics of the resilient spring connecting shaft 21 and the second plastic folding tube 19, the polarization effect of the polarized stator 23 is realized. The rubber contact head 25 uses this polarization effect to high-frequency vibrate one outer wall of the conical ring plate 15, thus achieving three effects: 1. Vibration accelerates the flow rate of the materials on the conical ring plate 15, avoiding stacking; 2. Through this vibration, slight mixing of the materials on the conical ring plate 15 is realized, and the mixing density of the materials is increased, realizing the seventh mixing; 3. Through this vibration, the blockage of the circulation holes 16 on the conical ring plate 15 can be effectively avoided, thus affecting the dripping effect of the mixed materials; at the same time, the rotation of the central axis holding beam 7 will drive the rubber contact head 25 to continuously rotate on the surface outer wall of the conical ring plate 15, ensuring the mixing uniformity rate of the materials on the conical ring plate 15.
