DETAILED DESCRIPTION

[0025] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0026] As shown Figures 1 - 4 in the figure, this embodiment provides a stirring device for concrete mixing, including a stirring bin 1. A motor 2 is installed at the middle position on the top of the stirring bin 1. A rotating shaft 3 is fixed to the output shaft of the motor 2, and the bottom end of the rotating shaft 3 penetrates and extends into the interior of the stirring bin 1. Cleaning plates are symmetrically arranged at the bottom of the rotating shaft 3, and the cleaning plates are triangular cleaning plates. The triangular cleaning plates are convenient for turning over the raw materials sinking in the interior of the stirring bin 1, improving the stirring efficiency. A stirring blade 4 is arranged at the lower end position of the rotating shaft 3. Raw material bins 6 are symmetrically installed on the top of the stirring bin 1. Feed pipes 7 are arranged at the bottoms of the raw material bins 6, and the bottom ends of the feed pipes 7 penetrate and extend into the interior of the stirring bin 1. A conveying pipe 8 is fixed to the bottom end of the feed pipe 7, and one end of the conveying pipe 8 is fixedly connected to the inner side wall of the stirring bin 1. A reinforcing plate is fixed to the outer side of the conveying pipe 8 near one end of the bevel gear two 10, and the top of the reinforcing plate is fixedly connected to the bottom of the raw material bin 6. The arrangement of the reinforcing plate increases the fixing points for the conveying pipe 8, improving the firmness of the installation of the conveying pipe 8. A spiral pushing rod 9 is rotatably installed in the interior of the conveying pipe 8, and the end of the spiral pushing rod 9 penetrates and extends to the outside of the conveying pipe 8. Bevel gears two 10 are fixed to the ends of the spiral pushing rod 9 near the bevel gear one 5, and the bevel gears two 10 are meshed with the bevel gear one 5. Feeding openings 11 are evenly opened at the end of the conveying pipe 8 near the bevel gear two 10. A water inlet pipe 12 is installed through one side of the stirring bin 1. A mixing component 21 is arranged between the rotating shaft 3 and the stirring bin 1.

[0027] Specifically, more than one kind of raw materials are respectively put into the interior of the raw material bin 6. The motor 2 is started, and the motor 2 drives the rotating shaft 3 and the bevel gear one 5 to rotate. The bevel gear one 5 drives the bevel gear two 10 and the spiral pushing rod 9 to rotate. At the same time, the raw materials in the raw material bin 6 enter the conveying pipe 8 through the feed pipe 7. The raw materials are pushed to the discharging position of the feeding opening 11 by the spiral pushing rod 9, and the raw materials are conveyed into the interior of the stirring bin 1 through the evenly distributed feeding openings 11. The rotating shaft 3 drives the stirring blade 4 to mix and stir the raw materials entering the stirring bin 1.

[0028] As shown Figure 1 、 Figure 2 and Figure 4As shown in the figure, the mixing component 21 includes a sleeve 13 and a mixing cylinder 16. The sleeve 13 is sleeved outside the rotating shaft 3. Arc-shaped plates 20 are evenly arranged on the outside of the sleeve 13 and below the mixing cylinder 16. The arc-shaped plates 20 are all inclined on the outside of the sleeve 13. The arc-shaped plates 20 disperse the falling raw materials to further improve the mixing speed of the raw materials. Scrapers 14 are evenly arranged on the top side wall of the sleeve 13. The number of the scrapers 14 is set to two groups, and the two groups of scrapers 14 are all inclined on the outside of the sleeve 13. The inclined scrapers 14 make it easier for the raw materials falling on the scrapers 14 to slide into the interior of the mixing cylinder 16 under the action of gravity, reducing the accumulation of raw materials on the scrapers 14. Comb-shaped blocks 15 are evenly arranged at the bottoms of the scrapers 14. The mixing cylinder 16 is installed inside the stirring bin 1 and below the material conveying pipe 8. The mixing cylinder 16 is movably connected to the scrapers 14 and the comb-shaped blocks 15.

A sieve 17 is evenly arranged at the bottom of the mixing cylinder 16.

[0029] Specifically, when the rotating shaft 3 rotates, it drives the scrapers 14 and the comb-shaped blocks 15 to rotate inside the mixing cylinder 16. The raw materials in the material conveying pipe 8 also enter the interior of the mixing cylinder 16 through the feeding port 11 and accumulate in the mixing cylinder 16. When the staggered comb-shaped blocks 15 rotate, they push the raw materials on the left side to the right side and simply mix with the raw materials on the right side and then discharge them from the sieve 17. The raw materials fall from the mesh holes of the sieve 17 into the stirring bin 1.

[0030] As Figure 1 shown, through openings 18 are provided on the outside of the raw material bin 6, and scale plates 19 are fixed inside the through openings 18.

[0031] Specifically, the amount of raw materials put into the interior of the raw material bin 6 is judged according to the observation of the through openings 18 and the scale plates 19, so as to facilitate the faster distribution and replenishment of the raw materials.
