[0003] In the production process of concrete admixtures, mixing devices are frequently used. Although existing mixing devices can achieve basic mixing functions in actual use, their limited stirring range and the tendency of raw materials to form a fixed circulation under the action of gravity and centrifugal force make it difficult for materials with different densities and viscosities to fully mix, often resulting in localized uneven mixing. Therefore, improvements are needed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5 As shown, this utility model provides a concrete admixture mixing device, including a support leg 1, a mixing tank 2 fixedly connected to the top of the support leg 1, a protective shell 3 movably connected to the top of the mixing tank 2, a mixing motor 4 fixedly installed inside the protective shell 3, a mixing shaft 5 fixedly sleeved at the other end of the output shaft of the mixing motor 4, the bottom of the mixing shaft 5 passing through the protective shell 3 and the mixing tank 2 in sequence and extending into the interior of the mixing tank 2 and fixedly sleeved with a mixing blade 6, a support plate 7 fixedly connected to the top of the mixing tank 2, a drive motor 8 fixedly connected to the outside of the support plate 7, a double threaded screw 9 fixedly sleeved at the other end of the output shaft of the drive motor 8, the left side of the double threaded screw 9 passing through the support plate 7 and extending into the interior of the support plate 7, a movable plate 10 threadedly sleeved on the outer surface of the double threaded screw 9, two movable plates 10, a connecting rod 11 hinged to the bottom of each of the two movable plates 10, and the other end of the connecting rod 11 hinged to the top of the protective shell 3.
[0023] When the drive motor 8 is running, the double threaded screw 9 will rotate, causing the two movable plates 10 to move in opposite directions. This, in turn, causes the two connecting rods 11 to rotate, causing the protective shell 3 to move upward. This, in turn, causes the stirring motor 4, stirring shaft 5, and stirring blade 6 to move upward as a whole, thus achieving the purpose of more uniform mixing of the additives.
[0024] Among them, the inner side of the support plate 7 is fixedly connected with a limiting rod 12, and there are two limiting rods 12. The outer surfaces of the two limiting rods 12 are movably sleeved with the inner surface of the movable plate 10.
[0025] The design of the two limit rods 12 serves to limit the movement of the two movable plates 10, ensuring the stability of the horizontal movement of the two movable plates 10.
[0026] Among them, a limiting ring 13 is fixedly sleeved on the outer surface of the stirring shaft 5, and the limiting ring 13 is circular in appearance.
[0027] The design of the limiting ring 13 serves to limit the lifting and lowering of the stirring shaft 5, preventing the stirring blade 6 from colliding with the top of the inner cavity of the stirring tank 2 during the rising process of the stirring shaft 5.
[0028] The top of the mixing tank 2 is fixedly connected to the inlet 14, and the bottom of the mixing tank 2 is fixedly connected to the outlet 15.
[0029] This design allows additives to be added into the mixing tank 2 through the feed inlet 14, and the mixed additives to be discharged through the discharge outlet 15.
[0030] The bottom of the discharge port 15 is hinged to a cover plate 16, and the inside of the cover plate 16 is threaded to a threaded rod 17. The top of the threaded rod 17 passes through the discharge port 15 and extends into the interior of the discharge port 15.
[0031] The downward movement of the rotating threaded rod 17 will contact the fixing effect on the cover plate 16. At this time, pulling the threaded rod 17 to rotate the cover plate 16 will release the sealing effect on the bottom of the discharge port 15.
[0032] The top of the mixing tank 2 is fixedly connected to a lifting motor 18 located behind the protective shell 3. The other end of the output shaft of the lifting motor 18 is fixedly sleeved with a rotating shaft 19, and a rotating rod 20 is fixedly sleeved on the outer surface of the rotating shaft 19.
[0033] The lifting motor 18 has a built-in self-locking structure that can lock the rotating shaft 19 and the rotating rod 20, preventing the rotating rod 20 from reversing.
[0034] Among them, a round shaft 21 is fixedly sleeved inside the other end of the rotating rod 20, and a lifting plate 22 is movably connected to the outer surface of the round shaft 21. A round rod 23 is fixedly connected to the bottom of the lifting plate 22. The bottom of the round rod 23 penetrates through the mixing tank 2 and extends into the interior of the mixing tank 2 and is fixedly connected to a scraper ring 24. The outer surface of the scraper ring 24 is movably connected to the inner surface of the mixing tank 2.
[0035] The rotation of the round shaft 21 will squeeze the lifting plate 22 and drive it to move downward, which in turn will drive the two round rods 23 and the scraper ring 24 to move downward, thus achieving the purpose of automatically scraping off the residual raw materials on the inner wall of the mixing tank 2.
[0036] Working principle and usage process of this utility model:
[0037] When producing and processing the additives for the mixed soil, the raw materials are first poured into the mixing tank 2 through the inlet 14. Then, the stirring motor 4 is started, which causes the stirring shaft 5 to drive the stirring blades 6 to rotate and mix the raw materials. At the same time, the drive motor 8 is started, which causes the double threaded screw 9 to rotate and drive the two movable plates 10 to move in opposite directions. This causes the two connecting rods 11 to rotate and drive the protective shell 3 to move upward. This, in turn, drives the stirring motor 4, stirring shaft 5 and stirring blades 6 to move upward as a whole. As the stirring blades 6 move up and down and rotate synchronously, the purpose of mixing the additives more evenly is achieved. When the raw materials are mixed, the rotating threaded rod 17 moves downward and contacts the cover plate 16 to fix it. The raw materials are then discharged and collected through the discharge port 15.
[0038] When there is raw material residue on the inner wall of the mixing tank 2, the lifting motor 18 is started, which will cause the rotating shaft 19 to drive the rotating rod 20 to rotate, which in turn causes the round shaft 21 to rotate and squeeze the lifting plate 22 and drive it to move downward. This causes the two round rods 23 to drive the scraper ring 24 to move downward, thus achieving the purpose of automatically scraping off the raw material residue on the inner wall of the mixing tank 2 and avoiding waste of raw materials.
