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.

[0036] Reference Figure 1-Figure 3 The utility model provides an embodiment: an automatic concrete batching mixer, including a bracket 1, a bracket 2 2 is fixedly connected to the top of the bracket 1, a hopper 5 is fixedly connected to the top of the bracket 2, a support plate 6 is slidably connected to the inside of the bracket 2, a discharge barrel 7 is fixedly connected to the inside of the support plate 6, a baffle 1 8 is fixedly connected to the outer wall of the discharge barrel 7, a bottom plate 10 is rotatably connected to the bottom of the discharge barrel 7, a baffle 2 11 is fixedly connected to the bottom of the bracket 2, a motor 3 is fixedly connected to one side of the bracket 2, a disc 4 is fixedly connected to the output end of the motor 3, a connecting rod 9 is rotatably connected to the inside of the disc 4, one end of the connecting rod 9 is rotatably connected to the inside of the support plate 6, a fixed block 12 is fixedly connected to the top of the bracket 1, and a fixed A motor 2 13 is fixedly connected to one side of the fixed block 12, a threaded rod 14 is fixedly connected to the output end of the motor 2 13, a material receiving barrel 16 is threadedly connected to the outer wall of the threaded rod 14, a limiting assembly is arranged on one side of the fixed block 12, a material delivery pipe 17 is fixedly connected to the inside of the material receiving barrel 16, one end of the material delivery pipe 17 is fixedly connected to a stirring tank 18, a motor 3 24 is fixedly connected to the top of the stirring tank 18, a rotating shaft 22 is fixedly connected to the output end of the motor 3 24, a stirring rod 25 is fixedly connected to the outer wall of the rotating shaft 22, a discharge pipe 20 is fixedly connected to the outer wall of the stirring tank 18, and the limiting assembly includes a limiting rod 15, one end of the limiting rod 15 is fixedly connected to one side of the fixed block 12, and the outer wall of the limiting rod 15 is slidably connected to the inside of the material receiving barrel 16.

[0037] Specifically, first, the operator will accurately put various raw materials into the hopper 5 in a certain proportion according to the engineering requirements and the concrete strength requirements. These raw materials may include cement, sand, gravel, etc. Then, the motor 2 13 starts to work, and its output end drives the threaded rod 14 to rotate. The threaded rod 14 is connected to the receiving barrel 16, and through its rotation, the receiving barrel 16 is accurately moved to the bottom of the hopper 5. This step is to ensure that the raw materials can smoothly enter the receiving barrel 16 from the hopper 5. Then, the motor 13 starts to run, and its output end drives the disc 4 to rotate. The disc 4 is connected to the discharge barrel 7 on the support plate 6 through the connecting rod 9. When the disc 4 rotates, it drives the discharge barrel 7 to align with the bottom of the hopper 5. At the same time, the bottom plate 10 presses against the bottom of the discharge barrel 7 through the baffle 2 11 to close it. In this way, the raw materials inside the hopper 5 can fall into the discharge barrel 7 accurately. When the discharge barrel 7 is full of raw materials, the disc 4 continues to rotate and drives the support plate 6 to extend through the connecting rod 9. During this process, baffle 1 8 will seal the bottom of the hopper 5 to prevent the raw materials from leaking. Subsequently, since the bottom plate 10 is not blocked by baffle 2 11, the raw materials inside the discharge barrel 7 will smoothly fall into the receiving barrel 16 at the bottom. Once the receiving barrel 16 receives the raw materials, the raw materials will be transported to the inside of the mixing tank 18 through the feeding pipe 17. Here, the motor 3 24 starts working, and its output end drives the rotating shaft 22 to rotate. The rotating shaft 22 further drives the stirring rod 25 to stir and mix the concrete. This step is to ensure that the various raw materials in the concrete can be fully mixed to achieve the required strength and uniformity. Finally, the mixed concrete will be discharged through the discharge pipe 20 for further use or transportation.

[0038] Reference Figure 4 and Figure 5 A sleeve 19 is fixedly connected to the top of the mixing tank 18, a water inlet pipe 21 is fixedly connected to the outer wall of the sleeve 19, a sealing ring 23 is fixedly connected inside the sleeve 19, the inner wall of the sealing ring 23 is attached to the outer wall of the rotating shaft 22, a water distribution pipe 26 is fixedly connected inside the rotating shaft 22, a nozzle 27 is fixedly connected inside the water distribution pipe 26, a scraper 28 is fixedly connected to one side of the water distribution pipe 26, one side of the scraper 28 is attached to the inner wall of the mixing tank 18, and the outer wall of the rotating shaft 22 is penetrated inside the sleeve 19;

[0039] Specifically, when it is necessary to clean the inside of the mixing tank 18, firstly, external cleaning water is connected through the water inlet pipe 21. The cleaning water is connected to the inside of the sleeve 19 through a specific pipe system. The sleeve 19 is an important component installed inside the mixing tank 18. It cooperates closely with the rotating shaft 22 and together constitutes the core part of the cleaning system. After the cleaning water enters the sleeve 19, it enters the inside of the rotating shaft 22 through a specific channel. The rotating shaft 22 is a key component of the mixing tank. It can not only drive the mixing blades to stir the materials, but also play a key role in cleaning. Through the internal channel of the rotating shaft 22, the cleaning water is conducted to the nozzle 27 on the water distribution pipe 26. The nozzle 27 is a well-designed device that can spray the cleaning water at an appropriate angle and force to directly flush the inner wall of the mixing tank 18. In order to ensure the cleaning effect, a sealing ring 23 is used between the rotating shaft 22 and the sleeve 19 for sealing. The presence of the sealing ring 23 can not only effectively prevent the leakage of the cleaning water, but also ensure that the rotating shaft 22 will not be disturbed by external impurities when rotating. This design not only ensures the thoroughness of cleaning, but also prolongs the service life of the equipment. Subsequently, the output end of the motor 3 24 drives the rotating shaft 22 to rotate. The motor 3 24 is a power source specially designed for the cleaning system, which can provide a stable rotation speed and sufficient power. Driven by the motor, the rotating shaft 22 cleans the inner wall of the mixing tank 18 through the scraper 28. The scraper 28 is made of wear-resistant and corrosion-resistant materials, and can effectively scrape off the residues and impurities on the inner wall when rotating.

[0040] Working principle: When using the automatic concrete batching mixer, first put the raw materials of the required proportion into the hopper 5, then the output end of the motor 2 13 drives the threaded rod 14 to rotate, and the threaded rod 14 moves through the receiving barrel 16 to move the receiving barrel 16 to the bottom of the hopper 5, then the output end of the motor 13 drives the disc 4 to rotate, and the disc 4 drives the discharge barrel 7 on the support plate 6 to align with the bottom of the hopper 5 through the connecting rod 9, and at the same time, the bottom plate 10 is pressed against the bottom of the discharge barrel 7 through the baffle 2 11, and then the raw materials in the hopper 5 fall into the discharge barrel 7, then the disc 4 continues to rotate and drives the support plate 6 to extend through the connecting rod 9, and at the same time, the baffle 1 8 seals the bottom of the hopper 5 to prevent leakage, and then the bottom plate 10 is not blocked by the baffle 2 11, and the discharge barrel 7 The raw materials fall into the receiving barrel 16 at the bottom, and then the raw materials are transported to the mixing tank 18 through the feeding pipe 17. Then the output end of the motor three 24 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the stirring rod 25 to mix the concrete. The mixed concrete is discharged through the discharge pipe 20. When it is necessary to clean the inside of the mixing tank 18, the water inlet pipe 21 is connected to the external cleaning water, and then the cleaning water is connected to the inside of the sleeve 19. The cleaning water then enters the inside of the rotating shaft 22, is transmitted through the rotating shaft 22 to the nozzle 27 on the water distribution pipe 26, and is sprayed to the inner wall of the mixing tank 18. The rotating shaft 22 and the sleeve 19 are sealed by the sealing ring 23. Then the output end of the motor three 24 drives the rotating shaft 22 to rotate, and the rotating shaft 22 cleans the inner wall of the mixing tank 18 through the scraper 28.
