Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a stirring device for concrete production. Background Art

[0002] The concrete mixing device is an important and common device on construction sites, which is used to mix raw materials such as cement, sand, and gravel to make concrete. Its basic working principle is to thoroughly mix the raw materials through a rotating mixing barrel or mixing blades to ensure the uniformity and quality of the concrete. Among them, the disk-type mixing device has become one of the common devices in concrete production due to its advantages such as uniform mixing and convenient operation. However, in traditional technologies, the side walls of disk mixers often adhere to concrete, which can lead to insufficient mixing and easily cause concrete caking. Some disk mixers solve the adhesion problem of the side walls by setting scrapers. After retrieval, the Chinese patent with the application number CN202320498659.9 discloses a disk-type vibrating mixer, which is provided with a scraping assembly. The bottom scraper and the side scraper rotate synchronously with the stirring shaft to scrape the stirring cylinder wall, which can reduce the adhesion of concrete on the side walls. However, when the scraper is set to fit and stir with the stirring cylinder wall, the scraper will be worn during use, resulting in the scraper being difficult to closely fit with the stirring cylinder wall to scrape off the concrete, and the reliability is relatively low. Therefore, in the technical field of concrete, it is necessary to propose a concrete mixing device that can effectively and reliably prevent concrete from adhering to the side walls of the mixer. Summary of the Utility Model

[0003] Aiming at the above-mentioned prior art, the utility model aims to provide a stirring device for concrete production, and the main technical problem to be solved is how to effectively and reliably prevent concrete from adhering to the side walls of the mixer.

[0004] To achieve the above purpose, the technical solution of the embodiment of the utility model is realized as follows:

[0005] A stirring device for concrete production includes a cylinder body, a stirring mechanism, a support frame, and a scraping mechanism. The stirring mechanism includes a motor, a rotating shaft, and stirring blades. The scraping mechanism includes a connecting rod, a first scraper, and a first pressing mechanism. The upper and lower parts of the rotating shaft are respectively fixedly connected with the connecting rod. The two ends of the first scraper are respectively connected to the ends of the connecting rod on the upper and lower parts of the rotating shaft. The first pressing mechanism is arranged at the connection between one end of the first scraper and the connecting rod. The first pressing mechanism can squeeze or stretch the first scraper, so that the bending degree of the first scraper increases or decreases.

[0006] Preferably, the connecting rods on the upper and lower parts of the rotating shaft are arranged in a cross pattern.

[0007] Preferably, the first extrusion mechanism includes a threaded rod and a threaded sleeve. A through hole is provided at the end of the connecting rod, and a limiting groove is provided in the through hole. The threaded rod is provided with a limiting ring that cooperates with the limiting groove. The threaded rod passes through the through hole and is threadedly connected to the threaded sleeve, and the threaded sleeve is fixedly connected to the first scraping plate.

[0008] Preferably, a partition iron net is provided at the top of the cylinder body.

[0009] Preferably, an ellipsoidal cavity is provided at the bottom of the cylinder body.

[0010] Preferably, a second scraping plate is provided at the bottom of the cylinder body. One end of the second scraping plate is connected to the connecting rod at the lower part of the rotating shaft through the second extrusion mechanism, and the other end of the second scraping plate is fixedly connected to the bottom of the rotating shaft. The second extrusion mechanism is provided with the same structure as the first extrusion mechanism.

[0011] Preferably, a support seat is provided at the bottom of the ellipsoidal cavity.

[0012] The beneficial effect of the present utility model lies in that: in this application, by providing the scraping mechanism, the rotation of the rotating shaft can drive the first scraping plate to scrape the concrete adhered to the side wall of the cylinder body. When the first scraping plate is worn and it is difficult to fit with the side wall of the cylinder body, the first extrusion mechanism is adjusted to extrude the first scraping plate, so that the bending degree of the first scraping plate increases, and then the first scraping plate is pressed to fit with the side wall of the cylinder body. The first scraping plate can more effectively and reliably prevent concrete from adhering to the side wall of the mixer.

[0013] In summary, this application is provided with the scraping mechanism, and the first scraping plate is made to fit with the side wall of the cylinder body through the first extrusion mechanism, which can effectively and reliably prevent concrete from adhering to the side wall of the cylinder body.

[0022] Embodiment 1

[0023] Refer to the appendix Figures 1-4, this application provides a mixing device for concrete production, including a cylinder body 1, a mixing mechanism 2, a support frame 3 and a scraping mechanism 4. The mixing mechanism 2 includes a motor 5, a rotating shaft 6 and mixing blades 7. The scraping mechanism 4 includes a connecting rod 8, a first scraping plate 9 and a first extrusion mechanism 10. The upper and lower parts of the rotating shaft 6 are respectively fixedly connected with the connecting rod 8. The two ends of the first scraping plate 9 are respectively connected to the ends of the connecting rod 8 on the upper and lower parts of the rotating shaft 6. The first extrusion mechanism 10 is arranged at the connection between one end of the first scraping plate 9 and the connecting rod 8. In this embodiment, the first extrusion mechanism 10 is arranged at the connection between the first scraping plate 9 and the connecting rod 8 on the upper part of the rotating shaft 6. The lower end of the first scraping plate 9 is fixedly connected to the connecting rod 8 on the lower part of the rotating shaft 6. The first extrusion mechanism 10 can extrude or stretch the first scraping plate 9, so that the bending degree of the first scraping plate 9 increases or decreases. By setting the scraping mechanism 4, the rotation of the rotating shaft 6 can drive the first scraping plate 9 to scrape the concrete adhered to the side wall of the cylinder body 1. When the first scraping plate 9 is worn and it is difficult to fit with the side wall of the cylinder body 1, adjust the first extrusion mechanism 10 to extrude the first scraping plate 9, so that the bending degree of the first scraping plate 9 increases, and then press the first scraping plate 9 to fit with the side wall of the cylinder body 1. The first scraping plate 9 can more effectively and reliably prevent concrete from adhering to the side wall of the mixer. In summary, the device is provided with the scraping mechanism 4, and the first scraping plate 9 is made to fit with the side wall of the cylinder body 1 through the first extrusion mechanism 10, which can effectively and reliably prevent concrete from adhering to the side wall of the cylinder body.

[0024] Specifically, the connecting rods 8 on the upper and lower parts of the rotating shaft 6 are arranged in a cross pattern. When the first scraping plate 9 is arranged between the two connecting rods 8, the first scraping plate 9 has a spiral-like structure and fits with the side wall of the cylinder body 1. Thus, the first extrusion mechanism 10 can more effectively extrude the first scraping plate 9 to fit with the cylinder body 1, so as to improve the scraping effect on the adhered concrete.

[0025] Specifically, the first extrusion mechanism 10 includes a threaded rod 11 and a threaded sleeve 12. A through hole 13 is provided at the end of the connecting rod 8, and a limiting groove 14 is provided in the through hole 13. The threaded rod 11 is provided with a limiting ring 15 that cooperates with the limiting groove 14. The limiting ring 15 is arranged in the limiting groove 14, so that the threaded rod 11 can rotate relative to the through hole 13 but cannot move left and right relative to the through hole 13. The threaded rod 11 passes through the through hole 13 and is threadedly connected to the threaded sleeve 12. The threaded sleeve 12 is fixedly connected to the first scraper 9. In this embodiment, the threaded sleeve 12 and the first scraper 9 are fixedly connected by welding. It should be understood that this fixed connection can also be changed to a threaded connection, a snap connection or other common connection methods according to the material of the scraper and actual production. The first extrusion mechanism 10 can rotate in the through hole 13 by twisting the threaded rod 11, and then squeeze or stretch the first scraper 9 through the threaded sleeve 12 to adjust the bending degree of the first scraper 9, so that the first scraper 9 can closely fit the side wall of the cylinder body 1.

[0026] Specifically, a partition iron net 16 is provided at the top of the cylinder body 1. The partition iron net 16 can separate the outside and inside of the cylinder body 1, prevent items from falling into the cylinder body 1 during stirring, cause damage to the device or result in safety accidents, and improve the safety and reliability of the device.

[0027] Embodiment 2

[0028] Refer to the appendix Figures 1-4 , the difference between this embodiment and Embodiment 1 is that an ellipsoidal cavity 17 is provided at the bottom of the cylinder body 1. The ellipsoidal cavity 17 can increase the volume of the cylinder body 1 and reduce the accumulation of concrete at the bottom corners of the cylinder body 1, improving the stirring effect.

[0029] Specifically, a second scraper 18 is provided at the bottom of the cylinder body 1. One end of the second scraper 18 is connected to the connecting rod 8 at the lower part of the rotating shaft 6 through the second extrusion mechanism 19, and the other end of the second scraper 18 is fixedly connected to the bottom of the rotating shaft 6. The second extrusion mechanism 19 is arranged with the same structure as the first extrusion mechanism 10. The connection method of the second extrusion mechanism 19 with the connecting rod 8 and the second scraper 18 is also the same as the connection method of the first extrusion mechanism 10 with the connecting rod 8 and the first scraper 9. By providing the second scraper 18 and the second extrusion mechanism 19, the device can effectively control the second scraper 18 to fit the inner wall of the ellipsoidal cavity 17 for concrete scraping, improving the concrete scraping effect.

[0030] Specifically, a support base 20 is provided at the bottom of the ellipsoidal cavity 17. The support base 20 makes the placement of this device more stable and safe.

[0031] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
