DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Embodiment

[0019] Refer to Figures 1 - 3 As shown, a quantitative addition device for powder concrete admixture includes a material cylinder 1. One end of the top of the material cylinder 1 is provided with an addition port 4, and the center of the outer wall of the bottom of the material cylinder 1 is provided with a discharge port 5. A stirring structure 3 is arranged at the center of the interior of the material cylinder 1. The stirring structure 3 includes a central tube 6, connecting rods 9 welded at equal intervals on the outer wall of the bottom end of the central tube 6, a main shaft 10 rotatably connected to the center of the central tube 6, a first spiral blade 12 welded on the outer wall of the main shaft 10 inside the central tube 6, and a speed reduction motor set 2 installed on the outer wall of the top end of the material cylinder 1.

[0020] The bottom end of the main shaft 10 is located at the discharge port 5 of the material cylinder 1, and a second spiral blade 13 is welded on the outer wall of the main shaft 10 at the position of the discharge port 5. The first spiral blade 12 is different from the second spiral blade 13. The main shaft 10 is rotatably connected to the center of the material cylinder 1. The central tube 6 is installed at the center of the inner wall of the bottom end of the material cylinder 1. The main shaft 10 contacts the central tube 6 through a rotating disc 11 to maintain stability with each other.

[0021] The other end of the connecting rod 9 is installed at the top of the inner wall of the material cylinder 1 at the position of the discharge port 5, and the outer wall of the top end of the main shaft 10 is rotatably connected to the center of the top of the material cylinder 1.

[0022] The outer wall of the bottom end of the central tube 6 is provided with evenly distributed second material turning ports 8, and the outer wall of the central tube 6 at the top of the first spiral blade 12 is provided with evenly distributed first material turning ports 7. After the first spiral blade 12 on the main shaft 10 inside the central tube 6 rotates, it drives the admixture to enter the central tube 6 from the bottom of the material cylinder 1 and discharge from the first material turning ports 7 of the central tube 6, circulating and turning and stirring the admixture, which is convenient to ensure the looseness of the admixture and avoid caking and hardening.

[0023] A rotating disc 11 is welded on the outer wall of the top end of the main shaft 10 at the top of the central tube 6, and the bottom outer wall of the rotating disc 11 is slidably connected to the inner wall of the central tube 6. A scraping plate 14 is installed on the top outer wall of the rotating disc 11, and the scraping plate 14 is of an arc structure. One side outer wall of the scraping plate 14 is slidably connected to the inner wall of the material cylinder 1. The scraping plate 14 on the rotating disc 11 on the main shaft 10 is of an arc structure, which is convenient to scrape off the residual materials on the inner wall of the material cylinder 1 and avoid the materials remaining on the inner wall of the material cylinder 1.

[0024] The output shaft of the speed reduction motor set 2 is connected to the top end of the main shaft 10, and the speed reduction motor set 2 is connected to the switch through a wire, and the switch is connected to the power supply through a wire. After the speed reduction motor set 2 rotates forward, the second spiral blade 13 drives the admixture in the cylinder 1 to move downward and discharge from the discharge port 5, facilitating the conveying of materials.

[0025] Working principle: During use, the admixture is added into the interior through the addition port 4 at the top of the cylinder 1. After the addition is completed, to prevent the admixture from caking, the speed reduction motor set 2 is started to drive the main shaft 10 to rotate in the reverse direction. The first spiral blade 12 and the second spiral blade 13 on the main shaft 10 rotate in the reverse direction. At this time, the rotation of the second spiral blade 13 prevents the admixture from discharging from the discharge port 5. The first spiral blade 12 moves the material upward from the second turning port 8 to the first turning port 7, and the admixture discharges from the first turning port 7. The scraper 14 on the rotating disk 11 agitates the admixture at the inner edge of the cylinder 1, so that the admixture is always at the bottom center of the cylinder 1, facilitating the first spiral blade 12 to convey the admixture into the central pipe 6. This cycle facilitates the stirring of the admixture, avoids caking, and ensures the looseness of the admixture. After the speed reduction motor set 2 rotates forward, the second spiral blade 13 drives the admixture in the cylinder 1 to move downward and discharge from the discharge port 5, facilitating the conveying of materials.
