It is a commonly used specialized machine in construction engineering and plays an important role in improving construction progress and ensuring project quality. Currently, traditional concrete mixing plants typically perform feeding and mixing simultaneously, making it inconvenient to adjust the proportions of cement, sand, gravel, and water. The inaccurate proportions of each material affect the quality of the concrete. Furthermore, materials are generally added in batches, resulting in poor mixing and prolonged mixing time. Summary of the Invention

This invention solves the problems of traditional concrete mixing devices, where feeding and mixing are generally carried out simultaneously, making it inconvenient to adjust the proportions of materials such as cement, sand, gravel, and water. The proportions between various materials cannot be accurately matched, affecting the quality of the concrete. Furthermore, materials are generally added in batches, resulting in poor mixing effects and long mixing times.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A concrete mixing device for construction is characterized by comprising a frame, two water tanks symmetrically arranged at the upper end of the frame, a cement tank and a sand and gravel tank arranged between the two water tanks, a first discharge pipe at the lower end of the water tanks, cement tank and sand and gravel tank, two sliding plates slidably arranged on the frame below the water tanks, a weighing device fixedly connected to the sliding plates, a mixing cylinder arranged on the weighing device, a second discharge pipe at the lower end of the mixing cylinder, a first mixing component for mixing the contents of the mixing cylinder arranged on the sliding plates, two first push rod motors symmetrically arranged on both sides of the frame to drive the sliding plates, a mixing cylinder arranged on the frame below the second discharge pipe, the mixing cylinder having an opening, a second mixing component arranged on the mixing cylinder, and a third discharge pipe at the lower end of the mixing cylinder.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 2 As shown,

[0020] A concrete mixing device for construction is characterized by comprising a frame 2, two water tanks 3 symmetrically arranged on the upper end of the frame 2, a cement tank 4 and a sand and gravel tank 5 arranged between the two water tanks 3, a first discharge pipe 6 arranged at the lower end of the water tanks 3, cement tank 4 and sand and gravel tank 5, two sliding plates 7 slidably arranged on the frame 2 below the water tanks 3, a weighing device 8 fixedly connected to the sliding plate 7, a mixing cylinder 9 arranged on the weighing device 8, a second discharge pipe 10 arranged at the lower end of the mixing cylinder 9, a first mixing component arranged on the sliding plate 7 for mixing the contents of the mixing cylinder 9, two first push rod motors 11 symmetrically arranged on both sides of the frame 2 for moving the sliding plate 7, a mixing cylinder 12 arranged on the frame 2 below the second discharge pipe 10, the mixing cylinder 12 having an opening, a second mixing component arranged on the mixing cylinder 12, and a third discharge pipe 13 arranged at the lower end of the mixing cylinder 12.

[0021] In this embodiment, the first push rod motor 11 on one side drives the slide plate 7 to move below the water tank 3. The water tank 3 adds a fixed amount of water to the mixing drum 9 through the first discharge pipe 6. Then, the first push rod motor 11 drives the slide plate 7 to continue moving forward, and adds a fixed amount of cement and sand in sequence. Then, the first push rod motor 11 drives the slide plate 7 to move below the water tank 3 on the other side. At this time, the first stirring component performs preliminary stirring in the mixing drum 9. After preliminary stirring, the first push rod motor 11 drives the slide plate 7 to move back. During the movement, a fixed amount of water, cement, and sand are added again. Then, the first stirring component stirs it again. Then, the push rod motor on the other side drives the slide plate 7 on the other side to repeat the operation, so that the fixed amount of water, cement, and sand are also initially stirred in the mixing drum 9 on the other side. After the concrete in the mixing drum 9 is initially stirred, it is discharged through the second discharge pipe 10 and exits from the mixing drum 12. The concrete enters the mixing drum 12 through the opening, where the second mixing component further mixes the initially mixed concrete and stores it in the mixing drum 12. When concrete is needed, it is discharged through the third discharge pipe 13. The weighing device 8 senses the weight change of the mixing drum 9, making it easier to control the amount of material added each time, so that the ratio between various materials is more accurate and the quality of concrete is improved. The material is added to the mixing drum 9 in two stages, and after each addition, it is initially mixed by the first mixing component, resulting in a good mixing effect. The initially mixed concrete then enters the mixing drum 12 for further fine mixing, resulting in a good mixing effect and shortening the overall mixing time. After the mixing device is used up, the water tank 3 can also rinse the mixing drum 9 through the first discharge pipe 6. After rinsing, the mixing drum 12 is cleaned in conjunction with the first push rod motor 11, eliminating the need for external cleaning equipment and saving costs.

[0022] In this embodiment, the sliding plate 7 is provided with a plurality of limiting posts 14, which abut against the mixing cylinder 9. The limiting posts 14 prevent the mixing cylinder 9 from moving on the weighing device 8.

[0023] In this embodiment, the first stirring assembly includes a support frame 15, which is fixedly connected to a limiting post 14. A second push rod motor 16 is fixedly connected to the support frame 15. A first drive motor 17 is fixedly connected to the push rod of the second push rod motor 16. A first support rod 18 is fixedly connected to the output shaft of the first drive motor 17. A plurality of first stirring rods 19 are fixedly connected to the support rod. When it is necessary to perform preliminary stirring of the material in the mixing drum 9, the first drive motor 17 drives the first support rod 18 and the first stirring rods 19 to rotate, and the second push rod motor 16 drives the first support rod 18 and the first stirring rods 19 to extend into the mixing drum 9 to perform preliminary stirring of the material.

[0024] In this embodiment, a scraper 20 is provided at the end of the first stirring rod 19. The scraper 20 is provided to scrape off the concrete remaining on the inner wall of the mixing cylinder 9.

[0025] In this embodiment, the second mixing assembly includes a mixing auger 21, which is rotatably connected inside the mixing drum 12. The mixing drum 12 is equipped with a second drive motor 22 that drives the mixing auger 21 to rotate. The second drive motor 22 drives the mixing auger 21 to rotate, thereby re-mixing the concrete inside the mixing drum 12.

[0026] In this embodiment, guide plates 23 are symmetrically provided on the opening of the mixing drum 12. The guide plates 23 are provided to prevent concrete from falling outside the mixing drum 12.

[0027] In this embodiment, two symmetrical second support rods 24 are rotatably connected inside the third discharge pipe 13, and two second stirring rods 25 are fixedly connected to the second support rods 24. A third drive motor 26 is provided outside the third discharge pipe 13 to drive the second support rods 24 to rotate. When the third discharge pipe 13 discharges material, the third drive motor 26 drives the second support rods 24 and the second stirring rods 25 to rotate, thus preventing blockage when the third discharge pipe 13 discharges material.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
