[0002] Concrete composite admixtures refer to various auxiliary materials added to concrete in a certain proportion to improve the performance, characteristics or reduce the cost of concrete. These auxiliary materials can be powdery, granular or fibrous substances, usually mixed with cement, sand, aggregate and other main raw materials to make concrete. Composite admixture production equipment is required in concrete production to mix different types of admixtures together and mix them with cement, sand, aggregate and other main raw materials.
[0003] Traditionally, when concrete composite admixtures are produced and mixed, various admixtures need to be added for mixing. Due to the different properties and particle sizes of each admixture, traditional concrete composite admixture production equipment cannot crush the different added admixtures. Since the admixtures are not fully crushed, the bonding between the admixtures and the cement matrix is not tight, which affects the performance and durability of the concrete. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a concrete composite admixture production equipment, including a bracket 1, a mounting frame 2 is fixedly connected to the upper right side of the bracket 1, a mixing box 16 is fixedly connected inside the bracket 1, a feed bin 25 is fixedly connected inside the mounting frame 2, a first motor 4 is arranged outside the mounting frame 2, a driving wheel 5 is fixedly connected to the output end of the first motor 4, a mixing assembly 13 is arranged inside the driving wheel 5, a driven wheel 7 is arranged on the upper part of the driving wheel 5, the driving wheel 5 is connected to the driven wheel 7 through a belt 6, a rotating shaft 8 is fixedly connected inside the driven wheel 7, and a first gear 9 is fixedly connected outside the rotating shaft 8, and a first gear 9 is fixedly connected outside the first gear 9. The gear 9 is meshedly connected with the second gear 10 on the outside, and the first gear 9 and the second gear 10 are fixedly connected with a rotating rod 11 on the inside. The two rotating rods 11 are rotatably connected to the inside of the feed bin 25, and the two rotating rods 11 are fixedly connected to the outside of the crushing roller 12. The right side of the outside of the mounting frame 2 is fixedly connected to the cross plate 3, and the first motor 4 is fixedly connected to the upper part of the cross plate 3. Baffles 14 are fixedly connected to both sides of the inside of the feed bin 25, and a guide plate 15 is fixedly connected to the bottom of the feed bin 25. One end of the connecting pipe 24 is fixedly connected to the lower part of the feed bin 25, and the other end of the connecting pipe 24 is fixedly connected to the right side of the outside of the mixing box 16.
[0026] First, different types of admixtures are poured into the feed bin 25 according to a preset ratio. These admixtures may be materials from different sources such as ore, fly ash, slag, etc., and they have different particle sizes and physical properties. In order to ensure that these admixtures can be evenly distributed in the concrete, they need to be crushed first. With the start of the first motor 4, the driving wheel 5 starts to rotate. Through the transmission of the belt 6, the driven wheel 7 also starts to rotate, thereby driving the rotating shaft 8 and the first gear 9 thereon to rotate. When the first gear 9 and the second gear 10 rotate, they will drive the two rotating rods 11 and the crushing rollers 12 thereon to rotate. These crushing rollers 12 will generate strong shearing force when rotating at high speed, and crush the admixtures poured into the feed bin 25. In this way, admixtures of different sizes are crushed into particles of the same specifications, which is conducive to subsequent uniform dispersion and mixing in the concrete. After the crushing operation is completed, the admixture enters the mixing box 16 through the connecting pipe 24. At this time, the driving wheel 5 continues to rotate, driving the stirring rod 1302 to rotate through the transmission rod 1301. Scrapers 1304 are fixed on the mounting plate 1303 of the stirring rod 1302. These scrapers 1304 scrape and stir the inside of the mixing box 16 as the stirring rod 1302 rotates, ensuring that the admixtures can be fully mixed, making it easier to crush different types of admixtures before concrete production. Crushing can make the admixture particles more uniform, which is beneficial for dispersion and mixing in concrete, thereby improving the uniformity and consistency of the concrete.
[0027] Reference Figure 2 and Figure 5 A mixing box 16 is fixedly connected to the middle of the bracket 1, a conveying pipe 26 is fixedly connected to the lower part of the mixing box 16, a feeding pipe 18 is fixedly connected to the lower part of the feeding pipe 26, a second motor 20 is arranged on the right side of the outside of the feeding pipe 18, a rotating rod 21 is fixedly connected to the output end of the second motor 20, the rotating rod 21 is rotatably connected to the inside of the feeding pipe 18, a spiral conveying blade 22 is fixedly connected to the outside of the rotating rod 21, a discharge port 23 is fixedly connected to the left side of the outside of the feeding pipe 18, and the mixing component 13 includes a transmission rod 1301, one end of the transmission rod 1301 is fixedly connected Inside the driving wheel 5, the other end of the transmission rod 1301 is rotatably connected to the inside of the mixing box 16, and stirring rods 1302 are fixedly connected to the outside of the transmission rod 1301 on all sides, and multiple stirring rods 1302 are fixedly connected to the outside of mounting plates 1303, and multiple mounting plates 1303 are fixedly connected to the outside of scrapers 1304. Multiple scrapers 1304 fit the inner wall of the mixing box 16, and a transparent window 17 is installed on the left side of the outside of the mixing box 16, and a support plate 19 is fixedly connected to the right side of the outside of the discharge pipe 18, and the second motor 20 is fixedly connected to the upper part of the support plate 19.
[0028] When the concrete production is completed, the unloading task is performed by starting the second motor 20. The powerful power output of the second motor 20 drives the rotating rod 21 fixedly connected to its output end to start rotating. The rotation of the rotating rod 21 further drives the rotation of the spiral conveying blade 22 fixedly connected to the outside. The spiral structure can effectively transport the concrete that falls into the unloading pipe 18 from one end to the other. As the spiral conveying blade 22 continues to rotate, the concrete is gradually pushed toward the discharge port 23. When the concrete reaches the discharge port 23, due to the effect of gravity, the concrete is smoothly discharged from the inside of the discharge port 23, completing the unloading process, realizing the operation of facilitating the unloading of the produced concrete, avoiding part of the concrete from remaining in the unloading pipe 18, reducing the waste of concrete, and saving raw material costs.
[0029] Working principle: When using the concrete composite admixture production equipment, first pour different admixtures into the feed bin 25, and then start the first motor 4. The first motor 4 rotates the driving wheel 5 fixedly connected to the output end, and the driving wheel 5 rotates through the belt 6 to rotate the driven wheel 7. The driven wheel 7 rotates and rotates the rotating shaft 8 fixedly connected inside. The rotating shaft 8 rotates and rotates the first gear 9 fixedly connected outside. The first gear 9 rotates and rotates the second gear 10 meshingly connected outside. When the first gear 9 and the second gear 10 rotate, the two rotating rods 11 fixedly connected inside rotate. The two rotating rods 11 rotate and the two crushing rollers 12 fixedly connected outside rotate relative to each other, and the admixture poured into the feed bin 25 is crushed, and admixtures of different sizes are crushed to become admixtures of the same specifications. Then, the crushed admixtures enter the mixing box 16 through the connecting pipe 24, and the driving wheel 5 rotates and drives the transmission rod 1301 to rotate. The transmission rod 1301 rotates and drives the external surrounding fixed admixtures. The connected stirring rod 1302 rotates, and the stirring rod 1302 rotates with the externally fixed mounting plate 1303, and the mounting plate 1303 rotates with the externally fixed scraper 1304 to mix the admixture inside the mixing box 16, so that different types of admixtures can be crushed before concrete production. Crushing can make the admixture particle size more uniform, which is conducive to dispersion and mixing in concrete, thereby improving the uniformity and consistency of concrete. Then, when it is necessary to discharge the produced concrete, by starting the second motor 20, the second motor 20 rotates with the rotating rod 21 fixedly connected to the output end, and the rotating rod 21 rotates with the externally fixed spiral conveying blade 22, and the spiral conveying blade 22 rotates to discharge the concrete that falls into the inside of the discharge pipe 18 from the inside of the discharge port 23, so that the production of concrete can be easily discharged, and part of the concrete is avoided from being left inside the discharge pipe 18, which can reduce the waste of concrete and save the cost of raw materials.
