[0015] In conclusion, the technical effects and advantages of the present application are as follows:

[0016] 1. This utility model has a reasonable structure. Various materials are placed into different material bins according to proportions through the feeding box. This reduces the problems of uneven mixing caused by the large volume of raw materials during feeding, which is common in previous devices. This can lead to problems in subsequent reaction processes and affect the quality of the water-reducing agent. The different material bins in the feeding box allow for more thorough mixing, resulting in better subsequent reactions and higher quality water-reducing agents. The gear motor drives the gears, which in turn rotate the grinding wheel inside the shaft seat. This reduces the risk of material splashing caused by excessive grinding force when using toothed rollers to crush large materials, which could lead to injury or production accidents due to the toxicity of some materials. The grinding wheel achieves significantly improved crushing efficiency. The process is gentler and the pulverization is more thorough, resulting in more complete mixing and reaction, and a more outstanding quality of the water-reducing agent. The scraper on the lower surface of the frame removes the residue, reducing the problems of traditional pulverizing devices where sticky materials accumulate on the grinding wheel, causing malfunctions and even machine damage, significantly impacting subsequent production. The scraper continuously removes these deposits, ensuring continuous and safe operation, greatly improving safety and practicality. The screw-driven rotating rod rotates within the limiting slider, which in turn slides within the limiting groove, reducing the problem of excessive mixing that often occurs due to a lack of quantitative control over material mixing, thus preventing adverse reactions. The limiting slider controls the precise amount of different materials within a scientifically defined range, strictly guaranteeing the quality of the water-reducing agent.

[0017] 2. In this utility model, the processed materials arrive at the mixing tank, and the stirring motor drives the staggered stirring blades to rotate. This reduces the problem of incomplete mixing in previous devices, which led to material accumulation and insufficient mixing, affecting the reaction process after subsequent feeding. The staggered stirring blades achieve thorough mixing through layered, staggered, progressive mixing, ensuring the normal progress of subsequent feeding and reactions, greatly enhancing the practicality of the device. The casters at the bottom of the mixing tank eliminate the drawbacks of previous devices that were immobile, restricting operation to specific locations and requiring users to wait for the reaction to finish before resuming use, significantly reducing practicality and leading to hidden resource waste and cost inefficiency. The casters allow for more flexible operation, enabling simultaneous feeding of one material while another reacts, greatly improving resource utilization efficiency and saving costs. During feeding, the support motor drives the support screw to rotate, fixing the device in place. This avoids the problems caused by insufficient consideration of device stability during feeding, which could lead to serious movement and other issues. The material spillage device prevents splashing that could cause injury and production accidents. This new system, using a fixed support base, firmly anchors the device to the ground during feeding, significantly accelerating the feeding process and subsequent reactions. After mixing, a screw motor drives the screw to rotate, which slides through a sliding cover, allowing the mixture to pass through the connecting hood and reach the conveyor box. The conveyor motor then drives the auger shaft. This reduces the problems of material agglomeration and blockages during conveying that previously occurred in other devices, which could severely impact subsequent reactions. The improved system utilizes the abrasive properties of the auger shaft itself. The mixed materials are ground again to make the conveying process smoother. This slows down the reaction when the reaction conditions are not met, greatly ensuring a more complete reaction in the later stages. By rotating the internal support arm and the internal legs of the support block, the conveyor box can be adjusted to a suitable position for fixed conveying. This eliminates the previous problem of feeding materials at a fixed height, which caused incompatibility due to different reaction device heights, greatly affecting the use of the device and slowing down the feeding progress. By adjusting and fixing the height, the device can be made more flexible in operation and improve its practicality. Attached Figure Description

[0025] 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.

[0026] Example: Reference Figures 1-6 The device for feeding an early-strength water-reducing agent includes a feeding box 1, a frame 2 slidably connected inside the feeding box 1, a scraper 3 fixedly connected to the lower surface of the frame 2, a shaft seat 4 slidably connected inside the feeding box 1, a grinding wheel 5 rotatably connected inside the shaft seat 4, a gear 6 meshing with a gear on one side of the grinding wheel 5, a gear motor 7 inserted into one end of the gear 6, a limiting groove 8 fixedly connected to the lower surface of the feeding box 1, a limiting slider 9 slidably connected inside the limiting groove 8, a threaded rotating rod 10 rotatably connected to one side of the limiting slider 9, a mixing box 11 inserted into the lower surface of the feeding box 1, a mixing motor 12 fixedly connected inside the mixing box 11, a staggered mixing blade 13 inserted into one end of the mixing motor 12, casters 14 fixedly connected to the lower surface of the mixing box 11, a sliding cover 15 slidably connected to the lower surface of the mixing box 11, a lead screw 16 inserted into one side of the sliding cover 15, and a lead screw motor 17 inserted into one end of the lead screw 16.

[0027] As a preferred embodiment of this example, Figures 1 to 5The diagram shows a feeding box 1, with a frame 2 slidably connected inside the feeding box 1. A scraper 3 is fixedly connected to the lower surface of the frame 2. A bearing 4 is slidably connected inside the feeding box 1, and a grinding wheel 5 is rotatably connected inside the bearing 4. A gear 6 meshes with a gear on one side of the grinding wheel 5, and a gear motor 7 is inserted into one end of the gear 6. A limiting groove 8 is fixedly connected to the lower surface of the feeding box 1, and a limiting slider 9 is slidably connected inside the limiting groove 8. A threaded rotating rod 10 is rotatably connected to one side of the limiting slider 9. A mixing tank 11 is inserted into the lower surface of the feeding box 1, and a mixing motor 12 is fixedly connected inside the mixing tank 11. A staggered mixing blade 13 is inserted into one end of the mixing motor 12. A caster wheel 14 is fixedly connected to the lower surface of the mixing tank 11. A sliding cover 15 is slidably connected to the surface. A lead screw 16 is inserted into one side of the sliding cover 15, and a lead screw motor 17 is inserted into one end of the lead screw 16. A feeding slide plate is provided on one side of the feeding box 1. The feeding box 1 has three feeding boxes inside. The feeding box 1 has a groove inside that can be adapted to the frame 2. There are two grinding wheels 5, with a partial gap between them. The surface of the grinding wheels 5 has a granular coating. A handle is provided on one side of the mixing box 11. The lower surface of the mixing box 11 has a groove that can be adapted to the sliding cover 15. During use, various materials are put into different material boxes in proportion through the feeding box 1, which reduces the problem of uneven mixing caused by the large volume of raw materials when feeding, which is a common issue in previous devices. This addresses the issue of subsequent reaction problems affecting the quality of the water-reducing agent. By placing materials in different bins of the feeding box 1 according to different processing methods, the materials are more thoroughly mixed, resulting in a better subsequent reaction and higher quality water-reducing agent. The gear motor 7 drives the gear 6 to rotate, which in turn rotates the grinding wheel 5 inside the shaft seat 4. This reduces the risk of material splashing caused by excessive grinding force when using toothed rollers to crush large-volume materials in previous crushing devices. Since the materials are partially toxic, splashing could cause injury or production accidents. The grinding wheel 5 achieves a gentler and more thorough crushing process, thus improving the subsequent reaction quality. The mixing is more thorough, the reaction is more complete, and the quality of the water-reducing agent is significantly improved. The scraper 3 on the lower surface of frame 2 removes the residue, reducing the problem of large amounts of sticky materials adhering to the grinding wheel 5 after crushing, which could lead to malfunctions, machine damage, and significant impact on subsequent production. The scraper 3 continuously removes the residue, ensuring continuous and safe operation of the device, greatly improving safety and practicality. The screw rod 10 rotates within the limiting slider 9, and the limiting slider 9 slides within the limiting groove 8, reducing the problem of excessive mixing caused by the lack of quantitative control in material mixing, which severely affects subsequent mixing and reaction.This achieves the effect of strictly controlling the quantitative distribution of different materials within a scientifically defined range by limiting slider 9, thus rigorously ensuring the quality of the water-reducing agent.

[0028] like Figure 5 and Figure 6As shown, in this embodiment, a support motor 18 is fixedly connected inside the mixing tank 11. One end of the support motor 18 is inserted into a support screw 19, and one end of the support screw 19 is rotatably connected to a support base 20. The upper surface of the support base 20 is provided with four sliding columns. The support base 20 is slidably connected inside the mixing tank 11. A support base is rotatably connected to the lower surface of the support base 20. A connecting cover 21 is fixedly connected to the lower surface of the mixing tank 11. A conveyor box 22 is fixedly connected to the lower surface of the connecting cover 21. The connecting cover 21 is made of wear-resistant elastic rubber. The conveyor box 22 is rotatably connected to the lower surface of the mixing tank 11. A conveyor motor 23 is fixedly connected inside the conveyor box 22. One end of the conveyor motor 23 is inserted into an auger shaft 24. The surface of the auger shaft 24 is provided with a friction coating. A support block 25 is fixedly connected to one side of the conveyor box 22. A support arm 26 is rotatably connected to the lower surface of the support block 25. A support leg 27 is rotatably connected to the lower surface of the support arm 26. There are two support legs 27. An anti-slip support base is rotatably connected to the lower surface of the support leg 27. During use, the processed material arrives at the mixing box 11. The stirring motor 12 drives the staggered stirring blades 13 to rotate. This reduces the problem of incomplete mixing and material accumulation caused by previous devices, which affected the reaction process after subsequent feeding. The staggered stirring blades 13 achieve thorough mixing through layered staggered progressive mixing, further ensuring the normal progress of subsequent feeding reactions and greatly enhancing the device's efficiency. The practical effect is achieved by using the casters 14 at the bottom of the mixing tank 11, which reduces the drawbacks of the previous device's inability to move. This prevented operation from being confined to specific locations, and after the reaction was complete, the device had to wait until it finished before being used again, significantly reducing its practicality and leading to a hidden waste of resources and costs. The casters 14 make the device more flexible, allowing for simultaneous loading of one component while another is reacting, greatly improving resource utilization efficiency and saving costs. During loading, the support motor 18 rotates, driving the support screw 19 to rotate, which in turn supports and fixes the device in place via the support base 20, reducing the need for manual loading as in previous devices. The lack of consideration for securing the device led to serious movement, causing material spillage and personnel injuries, resulting in production accidents. The new support base 20 firmly fixes the device to the ground for material feeding, greatly accelerating the feeding process and subsequent reaction effects. After mixing, the screw motor 17 drives the screw 16 to rotate, sliding through the sliding cover 15. The mixture passes through the connecting cover 21 to the conveyor box 22, where the conveyor motor 23 drives the auger shaft 24. This reduces the problem of material agglomeration and blockage during conveying, which previously hindered subsequent reactions. The auger shaft 24's own grinding properties also contribute to this improvement.The mixed materials are ground again to ensure smoother transport and slow down the reaction if the reaction conditions are not met, thus ensuring a more complete reaction in subsequent stages. The internal support arm 26 of the support block 25 rotates, and the internal support leg 27 rotates, while the conveyor box 22 rotates to adjust to a suitable position for fixed transport. This eliminates the previous problem of feeding materials at a fixed height, which caused incompatibility due to varying reaction device heights, significantly impacting the device's usability and slowing down the feeding process. By adjusting and fixing the height, the device becomes more flexible in operation, improving its practicality.

[0029] The working principle of this practical application is as follows:

[0030] Various materials are fed into different material bins according to proportions through the feeding bin 1. The gear motor 7 drives the gear 6 to rotate, which in turn rotates the grinding wheel 5 inside the bearing seat 4. The grinding wheel 5 is then carried by the scraper 3 on the lower surface of the frame 2 and rotates inside the limiting slider 9 via the threaded rotating rod 10. The limiting slider 9 slides inside the limiting groove 8. The processed materials reach the mixing tank 11, where the mixing motor 12 drives the staggered mixing blades 13 to rotate. The bottom of the mixing tank 11 has casters 14. When the device is being fed, the support motor 18 drives the support screw 19 to rotate, which in turn supports the support seat 20 and fixes the device. After mixing is completed, the screw motor 17 drives the screw 16 to rotate. The mixture slides through the sliding cover 15 and passes through the connecting cover 21 to the conveying box 22. The conveying motor 23 drives the auger shaft 24 to rotate. The internal support arm 26 of the support block 25 rotates, and the internal support leg 27 rotates. The conveying box 22 rotates and is adjusted to a suitable position for fixed conveying.

[0031] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
