[0028] In combination with the accompanying drawings in the embodiments of the present invention, the present invention will be described in detail.
[0029] A concrete processing device includes a main cylinder 1. A driving mechanism is provided on the main cylinder 1. A rotating shaft 6 is connected to the driving mechanism. A stirring paddle 7 is fixedly connected to the rotating shaft 6. A conical surface 2 is provided on the inner wall of the main cylinder 1. The lower end of the rotating shaft 6 is rotatably connected to a turntable 12. The turntable 12 is conical. A feeding screw 17 is further provided in the main cylinder 1. The lower end of the main cylinder 1 is fixedly connected to a discharge pipe 3; the lower end of the main cylinder 1 is fixedly connected to a funnel 23. The lower end of the funnel 23 is fixedly connected to a vertical discharge pipe 24. A valve is installed in the discharge pipe 24. The lower end of the funnel 23 is fixedly connected to a plurality of inclined pipes 25. The positions of the plurality of inclined pipes 25 are all higher than the discharge pipe 24.
[0030] Refer to Figure 4-8 ,
[0031] When using the processing device, first, the staff fixes the main cylinder 1 on a small engineering vehicle through bolts, and then uses the small engineering vehicle to drive the main cylinder 1 to move. The staff adds the raw materials required for concrete processing into the main cylinder 1 in proportion. At this time, the turntable 12 can cooperate with the conical surface 2 to block the main cylinder 1, so that the space between the turntable 12 and the conical surface 2 is sealed.
[0032] After each raw material enters the main cylinder 1, by controlling the driving mechanism to drive the rotating shaft 6 to rotate, the rotating shaft 6 drives the stirring paddle 7 to stir the raw materials, so that each raw material is fully mixed to form concrete slurry.
[0033] After the concrete is stirred, the driving mechanism is used to control the rotating shaft 6 to move downward. The rotating shaft 6 drives the turntable 12 to move downward. At the same time, the sealing port between the turntable 12 and the conical surface 2 is opened, so that the concrete slurry can automatically flow downward along the conical surface 2 to realize the function of discharging the slurry. After flowing downward, it contacts the feeding screw 17.
[0034] At this time, the driving mechanism is used to control the feeding screw 17 to rotate. During the rotation of the feeding screw 17, the concrete slurry can be transmitted downward, and by using the characteristic of the uniform rotation of the feeding screw 17, the concrete slurry can be quantitatively discharged from the main cylinder 1 and finally discharged through the discharge pipe 3 at the lower end of the main cylinder 1.
[0035] The discharged concrete slurry drops into the funnel 23. When the construction mold is narrow, the valve in the discharge pipe 24 can be opened, and the concrete slurry can be directly discharged from the discharge pipe 24 to realize the function of concrete pouring.
[0036] When the construction mold is wide, the staff closes the valve in the discharge pipe 24. Since the positions of the multiple inclined pipes 25 are all higher than the discharge pipe 24, the concrete slurry can accumulate in the funnel 23. When the height of the concrete slurry reaches the inclined pipes 25, the concrete slurry can be discharged through the multiple inclined pipes 25 respectively. The multiple inclined pipes 25 discharge the concrete slurry at the same time, thereby expanding the coverage area of the concrete discharge. Compared with a single discharge pipe 24, it can reduce the flowing time of the concrete slurry to the surrounding area, thus improving the pouring efficiency.
[0037] Through the above structure, the composite functions of concrete mixing, quantitative conveying, and discharging and pouring can be realized. Therefore, in the case of limited construction space, there is no need for manual use of a trolley to move the finished concrete in the cement tanker to the construction site. Only by fixing this equipment on a small engineering vehicle can the on-site processing and pouring treatment of concrete be realized, saving time and labor costs.
[0038] The feeding screw 17 realizes the precise quantitative output of the concrete slurry through uniform rotation, solves the problem of flow rate fluctuation of traditional pumping equipment, realizes precise point pouring through a single discharge pipe 24, and is suitable for filling the gaps of precast components; the multiple inclined pipes 25 discharge materials at the same time, solving the problem of end segregation caused by long-distance transportation of traditional pumping equipment.
[0039] The inclined pipe 25 adopts a gradually shrinking pipe diameter design, which can accelerate the flow of the slurry compared with a straight pipe.
[0040] This equipment integrates the functions of mixing, quantitative transmission, and multi-form discharging. Compared with the combination of a mixing station, a transport vehicle, and a pumping equipment required by the traditional process, the process time is shortened.
[0041] Through mechanical structure innovation, this design realizes the full-process automation of concrete processing - transportation - pouring, conforms to the development trend of the intellectualization and integration of concrete machinery, and has remarkable technical advancement and market application potential.
[0042] Multiple through slots 8 are formed in the stirring paddle 7, and the length and width of the multiple through slots 8 gradually increase from bottom to top.
[0043] See Figure 5 ,
[0044] When using the stirring paddle 7 to stir each raw material, the multiple through slots 8 can reduce the resistance received by the stirring paddle 7 during rotation. At the same time, the raw materials pass through the through slots 8, and the generated shear force can promote the mixing of the raw materials.
[0045] The size of the through slots gradually increases from bottom to top, which can effectively guide the fluid to form a spiral upward tornado flow structure. The smaller through slots at the bottom provide higher shear force, which is beneficial to break droplets or particles; the larger through slots at the upper part reduce the flow resistance, promote the overall circulation, and avoid the appearance of a cylindrical rotation area at the bottom of the slots.
[0046] This design forms a gradient flow field by changing the cross-sectional area of the through slots; the smaller through slots at the lower part generate a strong shear zone, which is suitable for the dispersion of various raw materials of concrete; the larger through slots at the upper part enhance the axial flow and promote the fluid exchange between the upper and lower layers; the gradient change of the through slot area reduces the fluid impact force on the blade surface, and at the same time reduces the overall turbulent kinetic energy consumption through the guiding effect. This design can also avoid the concentrated impact of the fluid on the outer arc surface of the blade and extend the service life of the equipment.
[0047] Scrapers 9 are fixedly connected to both blades of the stirring paddle 7. The scrapers 9 are arc-shaped, and the two scrapers 9 are symmetrically arranged with the axis of the rotating shaft 6 as the center.
[0048] See Figure 5 ,
[0049] When stirring the concrete, the staff controls the rotating shaft 6 to drive the stirring paddle 7 to rotate counterclockwise. Due to the design that the two scrapers 9 are symmetrically arranged with the axis of the rotating shaft 6 as the center, there will be no large resistance when the stirring paddle 7 rotates counterclockwise, which is beneficial to the stirring treatment of the raw materials.
[0050] After the concrete stirring is completed, the staff then uses the driving mechanism to control the rotating shaft 6 to drive the stirring paddle 7 to move downward. At this time, the concrete slurry is automatically discharged. At the same time, since both scrapers 9 are arc-shaped, they can contact the conical surface 2. Then control the rotating shaft 6 to drive the stirring paddle 7 to rotate clockwise. During the counterclockwise rotation of the stirring paddle 7, the two scrapers 9 are used to scrape off the residual concrete slurry on the conical surface 2, and the scraped concrete slurry can flow downward automatically along the scrapers 9, so as to realize the function of cleaning the inner wall of the main cylinder 1 and prevent the concrete from piling up and coagulating.
[0051] This design solves the long-existing vicious cycle problem of wall sticking - residue - energy consumption in concrete mixing equipment through the collaborative optimization of structural innovation and material technology, and conforms to the technical development trend of intelligent cleaning of the mixing equipment.
[0052] An arc-shaped diversion groove 11 is provided between the blade of the stirring paddle 7 and the scraper 9.
[0053] See Figure 5 ,
[0054] The arc-shaped diversion groove 11 is beneficial to the downward flow of the scraped concrete slurry, so as to avoid the accumulation of the concrete slurry on the scraper 9 and cause coagulation, and further improve the self-cleaning effect.
[0055] Each end of the scraping blade 9 is provided with an inclined surface 10.
[0056] See Figure 5 ,
[0057] The inclined surface 10 is conducive to scraping the residual concrete slurry on the conical surface 2. When the scraping blade 9 scrapes the residual concrete slurry, the residual concrete slurry enters the surface of the blade scraping blade 9 along the inclined surface 10 and finally can flow downward along the diversion groove 11. The setting of the inclined surface 10 can prevent the residual concrete slurry from accumulating on the cross-section of the scraping blade 9 and reduce the residual concrete slurry at the edge of the scraping blade 9.
[0058] A plurality of retaining pieces 13 are fixedly connected to the surface of the turntable 12.
[0059] See Figure 5 ,
[0060] A plurality of retaining pieces 13 are fixedly connected to the surface of the turntable 12. Although the rotating shaft 6 and the turntable 12 are rotatably connected, when the rotating shaft 6 drives the stirring paddle 7 to rotate clockwise, the turntable 12 has separated from the main cylinder 1. At this time, the restriction of the turntable 12 has disappeared, and thus the rotating shaft 6 can also drive the turntable 12 to rotate. After the concrete slurry is discharged, it falls on the turntable 12, and then the turntable 12 can be used to throw out the concrete slurry. The plurality of retaining pieces 13 can ensure that the concrete slurry is thrown out along a fixed direction, so that the concrete slurry can be evenly distributed and avoid the formation of cavities when the feeding screw 17 conveys the concrete slurry, resulting in the inability to quantitatively discharge the concrete.
[0061] A sealing gasket 14 is fixedly connected to the outer ring of the turntable 12.
[0062] See Figure 5-6 ,
[0063] A sealing gasket 14 is fixedly connected to the outer ring of the turntable 12. The sealing gasket 14 further plays a role in sealing between the turntable 12 and the main cylinder 1. When the stirring paddle 7 rotates counterclockwise to stir the raw materials, the sealing gasket 14 on the turntable 12 can fit on the inner wall of the main cylinder 1 at this time. Since the rotating shaft 6 and the turntable 12 are rotatably connected, the sealing gasket 14 remains stationary under the action of friction and pressure and does not affect the normal stirring process of the stirring paddle 7, thus ensuring the sealing effect and avoiding the leakage of raw materials during the stirring of the raw materials.
[0064] A fixing plate 18 is fixedly connected inside the main cylinder 1. A rotating sleeve 20 is rotatably connected to the middle of the fixing plate 18. A sliding rod 16 is connected inside the rotating sleeve 20 in a limited sliding manner. A feeding screw 17 is fixedly connected to the sliding rod 16. A limiting plug 15 is fixedly connected to the lower end of the turntable 12. A socket 22 is fixedly connected to the thinner part at the upper end of the sliding rod 16. A limiting groove for cooperating with the limiting plug 15 is formed inside the socket 22. A spring 21 is sleeved on the thinner part at the upper end of the sliding rod 16. The spring 21 is located between the socket 22 and the rotating sleeve 20. A triangular block 19 is fixedly connected to the lower end of the fixing plate 18, and the inclined surface of the triangular block 19 faces downward.
[0065] See Figure 7-8 ,
[0066] When the rotating shaft 6 moves downward to drive the limiting plug 15 to move downward, the limiting plug 15 can be inserted into the socket 22. When the rotating shaft 6 drives the stirring paddle 7 to rotate clockwise to scrape the residual concrete slurry, the cooperation between the plug 15 and the socket 22 can synchronously drive the feeding screw 17 to rotate. The feeding screw 17 drives the rotating sleeve 20 to rotate on the fixing plate 18, achieving the effect of synchronously conveying the concrete slurry downward.
[0067] Through the above structure, it can be realized that while discharging the stirred concrete, the feeding screw 17 is controlled to rotate to discharge the concrete quantitatively, without the need for separate control of the feeding screw 17.
[0068] When the feeding screw 17 rotates clockwise, the blade at its uppermost end can come into contact with the triangular block 19. When the blade of the feeding screw 17 moves, it contacts from the lowest end of the inclined surface of the triangular block 19 to the highest end of the triangular block 19. During this process, the feeding screw 17 moves downward under its own force, and at the same time, the spring 21 is compressed by force, and the sliding rod 16 slides downward inside the rotating sleeve 20. When the blade of the feeding screw 17 disengages from the triangular block 19, the feeding screw 17 automatically resets upward under the action of the spring 21. This process realizes the function of vibrating the feeding screw 17, which can discharge the cavities doped in the concrete slurry, thereby further ensuring that the concrete can be discharged quantitatively; since the limiting groove inside the socket 22 has a certain depth, the slight up and down sliding of the feeding screw 17 caused by vibration will not cause the plug 15 to disengage from the socket 22, so that the feeding screw 17 will not lose power.
[0069] The driving mechanism includes two electric push rods 4. The moving ends of the two electric push rods 4 are fixedly connected with a lifting plate 3. A driving motor 5 is fixedly connected to the lifting plate 3. The rotating shaft 6 is fixedly connected to the output shaft of the driving motor 5.
[0070] See Figure 1-3 ,
[0071] When it is necessary to control the up or down movement of the rotating shaft 6, the lifting plate 3 is lifted or lowered by controlling the extension or contraction of the moving end of the electric push rod 4. The lifting plate 3 drives the rotating shaft 6 to move up or down, and the rotating shaft 6 is driven by the driving motor 5 to rotate, realizing the functions of concrete mixing and controlling the conveying screw 17 to convey concrete.

[0073] Step 1: Add each raw material required for processing concrete into the main cylinder 1;
[0074] Step 2: Use the stirring paddle 7 to rotate counterclockwise to stir each raw material;

[0076] Step 4: Control the rotating conveyor screw 17 to rotate to quantitatively discharge the concrete slurry downward, and the stirring paddle 7 rotates clockwise to clean the residual concrete slurry;
[0077] Step 5: The conveyor screw 17 vibrates to remove the cavity.
