DETAILED DESCRIPTION
[0028] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.
[0029] like Figure 1-5 The mixing device shown is for modifying concrete with rubber powder instead of recycled rubber, comprising a bracket 6, a horizontal tank body 1 is mounted on the bracket 6, a feeding port 2 is provided on the horizontal tank body 1, a discharge port 3 is provided at one end of the horizontal tank body 1, a stirring mechanism is installed inside the horizontal tank body 1, and sealing covers are installed on the discharge port 3 and the feeding port 2 to prevent materials from spilling out from the discharge port 3 and the feeding port 2 during mixing.
[0030] The stirring mechanism of the utility model comprises a stirring roller 9 and a motor 8, the motor 8 is fixed at one end of a horizontal tank body 1, the stirring roller 9 is rotatably installed inside the horizontal tank body 1, one end of the stirring roller 9 extends from the horizontal tank body 1 and is connected to the motor 8, the stirring roller 9 is transversely installed inside the horizontal tank body 1, and is driven to rotate by the motor 8.
[0031] At least three scrapers 15 are installed in the horizontal tank body 1 of the utility model. One side of the scraper 15 contacts the horizontal tank body 1. The other side of the scraper 15 is provided with two connecting legs 14 respectively located at both ends of the scraper 15. The connecting legs 14 are connected to the stirring roller 9. When the motor 8 rotates to drive the stirring roller 9 to rotate, the scraper 15 also rotates. Both ends of the scraper 15 are against the inner wall of the horizontal tank body 1, and all the materials accumulated at the bottom of the horizontal tank body 1 are turned upward, so that the materials are mixed more evenly and the mixing effect of the device is improved.
[0032] Specifically, a scraper ring 12 is placed between two mutually distant connection legs 14. When the scraper ring 12 slides inside the horizontal tank body 1, the connection legs 14 can limit the movement of the scraper ring 12. The scraper ring 12 is provided with a contoured groove 16 that slides with the scraper plate 15, and the outer wall of the scraper ring 12 contacts the horizontal tank body 1;
[0033] Specifically, the scraper 15 plays a certain role in limiting and guiding the movement of the scraper ring 12, so that the axis of the scraper ring 12 coincides with the axis of the horizontal tank body 1. When the scraper ring 12 slides, the outer wall is always in contact with the inner wall of the horizontal tank body 1, and the concrete attached to the inner wall of the horizontal tank body 1 is scraped off.
[0034] The upper end of the bracket 6 of the utility model is rotatably connected to the outer wall of the horizontal tank body 1, and a cylinder 5 for controlling the rotation of the horizontal tank body 1 around the connection between the bracket 6 and the horizontal tank body 1 is installed on the bracket 6. One end of the cylinder 5 is fixed on the ground, and the other end of the cylinder 5 is rotatably connected to a slider 4. A slide rail 17 is installed at the lower end of the horizontal tank body 1. The slide rail 17 is laid along the length direction of the horizontal tank body 1, and the slider 4 is slidably matched with the slide rail 17. The lower end of the discharge port 3 is located on the same horizontal plane as the bottom of the horizontal tank body 1. When the horizontal tank body 1 is tilted for unloading, it is more convenient to unload concrete from the discharge port 3.
[0035] Specifically, when unloading, the cylinder 5 is extended and retracted to rotate the horizontal tank body 1. The height of the discharge port 3 is lowered, and the scraper ring 12 inside the horizontal tank body 1 also slides to the end of the scraper 15 close to the discharge port 3. During the sliding process, the concrete on the inner wall of the horizontal tank body 1 and the scraper 15 is scraped off, so that the concrete is prevented from sticking to the inner wall of the horizontal tank body 1 and the scraper 15, affecting the normal operation of the device, and extending the service life of the device.
[0036] Specifically, a magnet 13 for attracting the scraper ring 12 is provided on the connecting leg 14 at one end away from the discharge port 3. When mixing materials, the magnet 13 can attract the scraper ring 12 to the connecting leg 14 to prevent it from sliding freely inside the horizontal tank body 1. When unloading, the horizontal tank body 1 is tilted, and the downward force generated by the weight of the scraper ring 12 is greater than the suction force of the magnet 13, so the scraper ring 12 can automatically slide toward the discharge port 3, ensuring the stability of the scraping range of the scraper ring 12;
[0037] Specifically, after unloading is completed, the cylinder 5 controls the horizontal tank body 1 to flip, so that the scraper ring 12 slides toward the end of the horizontal tank body 1 away from the discharge port 3, and is attracted by the magnet 13 when sliding to the connection leg 14. After the scraper ring 12 is attracted to the connection leg 14, the cylinder 5 controls the horizontal tank body 1 to return to a horizontal state.
[0038] The scraper ring 12, the inner wall of the horizontal tank body 1 and the surface of the scraper 15 of the utility model are all provided with wear-resistant and anti-stick coatings, which can extend the service life of the three and further prevent concrete from adhering to the inside of the device and affecting the normal operation of the device.
[0039] Specifically, a spring shock absorber 7 is installed on the bracket 6, the lower end of the spring shock absorber 7 is fixed on the ground, and an arc-shaped top cover is installed on the upper end of the spring shock absorber 7, which can be against the lower end of the horizontal tank body 1. The cylinder 5 and the spring shock absorber 7 are symmetrical to each other along the symmetry plane of the bracket 6, giving the horizontal tank body 1 two upward and mutually symmetrical supporting forces along the symmetry plane of the bracket 6, so that the horizontal tank body 1 can maintain a horizontal state when the device is mixing. In addition, the vibration generated during mixing can also be transmitted to the spring shock absorber 7, and buffering and shock absorption are achieved through the spring shock absorber 7.
[0040] The stirring roller 9 of the utility model comprises a rotating shaft 10 and a plurality of stirring rods 11. One end of the rotating shaft 10 is rotatably mounted in the horizontal tank body 1, and the other end of the rotating shaft 10 extends out of the horizontal tank body 1 and is connected to the motor 8. The stirring rods 11 are equidistantly mounted on the rotating shaft 10 along the length direction of the scraper 15. The plurality of stirring rods 11 rotate simultaneously, so that the mixing of the device is more uniform.
[0041] Specifically, the inner wall of the scraper ring 12 does not contact the end of the stirring rod 11 away from the rotating shaft 10 , and the stirring rod 11 on the rotating shaft 10 does not interfere with the sliding of the scraper ring 12 .
[0042] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
