Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a vibrating screen box for screening concrete aggregates. Background Technology

[0002] Concrete aggregates are granular materials that act as the skeleton and filler in concrete, typically accounting for 60% to 80% of the total concrete volume. Aggregates of different sizes need to be mixed in proportion to form a compact granular structure, reducing internal voids and improving strength and durability. Natural aggregates often contain impurities such as soil, stone powder, and weeds, while artificial aggregates may contain excessive amounts of needle-like or flaky particles or oversized stones (particles exceeding design requirements). Screening can remove these impurities, preventing them from reducing the bond between the aggregate and cement paste or causing shrinkage cracking in the concrete.

[0003] When using a vibrating screen for concrete aggregate screening, first securely install the equipment and debug it to ensure normal operation; then feed the material at a stable speed, and the vibrating motor drives the screen box to make the aggregate jump and screen, with small particles passing through the screen and large particles being discharged; after screening, aggregates of different particle sizes are collected and stored separately.

[0004] In existing technologies, some vibrating screens for concrete aggregates experience problems during feeding. Material accumulates at the feed inlet, causing uneven impact and uneven distribution of aggregates on the screen surface. In some areas, excessive aggregate buildup leads to insufficient screening, resulting in substandard aggregates being mixed into the finished product and reducing its quality. Therefore, this new vibrating screen for concrete aggregates addresses these issues. Utility Model Content

A rotating shaft 4 is fixedly connected to the drive end of the motor 3, driving the rotating shaft 4 to rotate. Two rotating rings 5 ​​are fixedly connected to the outside of the rotating shaft 4, transmitting rotational force to the two rotating rings 5. Annular openings 6 are provided on both the front and rear sides of the rotating rings 5, providing space for movement. A transmission column 7 is slidably connected inside the annular opening 6, guiding the rotation of the rotating rings 5. Two drive columns 7 are externally fixedly connected to open plates 8, and the rotational force is transmitted to the open plates 8 through the drive columns 7. The rotating shaft 4 is externally fixedly connected to the inside of the drive wheel 32, and the rotational force is transmitted to the drive wheel 32 through the rotating shaft 4.

[0036] Reference Figures 1 to 3Screening frame 1 has a sliding connection to a screening plate 9, which is used for secondary screening. The bottom side of screening plate 9 is fixedly connected to the top side of two open plates 8 by welding, allowing the open plates 8 to transmit sliding force to screening plate 9. The top side of screening plate 9 is fixedly connected to two connecting plates 10 by welding, providing support for the connecting plates 10. The top side of the two connecting plates 10 is fixedly connected to a screening plate 11, which is used for primary screening. The outside of screening plate 11 is slidably connected to the inner wall of screening frame 1, allowing it to slide stably due to the constraint of screening frame 1. Side blocks 12 are fixedly connected to opposite sides of the two connecting plates 10 by welding, providing support for the side blocks 12. A guide rod 13 is slidably connected inside the side blocks 12, guiding the sliding of the side blocks 12.

[0037] Two guide rods 13 are fixedly connected to the front and rear ends of the screening frame 1 respectively, and are fixed by welding to ensure stable guidance. A belt 14 is fitted around the drive wheel 32, and friction causes the drive wheel 32 to rotate the belt 14. A feeding frame 15 is fixedly connected to the top left end of the screening frame 1, guiding the raw material into the screening frame 1. A driven shaft 16 is rotatably connected inside the feeding frame 15, allowing it to rotate stably. Multiple separation plates 17 are fixedly connected to the outside of the driven shaft 16, rotating to ensure uniform material entry into the screening frame 1. Limiting rings 18 are fixedly connected to both ends of the driven shaft 16 to prevent movement. A driven wheel 19 is fixedly connected to the rear end of the driven shaft 16, transmitting rotational force to the driven shaft 16 via the driven wheel 19. The driven wheel 19 is sleeved inside the belt 14, transmitting rotational force to the driven wheel 19 via the belt 14. A collection frame 20 is slidably connected to the bottom end of the screening frame 1 for collecting the screened raw materials. The driven wheel 19 is sleeved inside the belt 14, transmitting rotational force to the driven wheel 19 via the belt 14.

[0038] Reference Figure 4 , Figure 6 and Figure 7The screening plate 9 has an internal sliding connection to a misalignment plate 21, which adjusts the screening grade by misaligning the screening plate 9 with the misalignment plate 21. A rotating column 22 is rotatably connected to the right end of the screening plate 9, allowing the rotating column 22 to rotate stably due to the constraint of the screening plate 9. A sliding ring 23 is slidably connected to the outside of the rotating column 22, allowing the sliding ring 23 to slide stably due to the constraint of the rotating column 22. Two transmission blocks 24 are fixedly connected to the inner wall of the sliding ring 23, driving the two transmission blocks 24 to slide synchronously. The bottom side of the transmission block 24 is fixedly connected to the top of the spring 26. During the sliding process, the transmission block 24 compresses the spring 26, allowing the spring 26 to store elastic potential energy, which then provides a force in the opposite direction to the transmission block 24 for resetting. A guide shaft 25 is slidably connected inside the transmission block 24, providing guidance for the sliding of the transmission block 24. A spring 26 is sleeved on the outside of the transmission block 24. By restricting the spring 26, the spring 26 can be evenly stressed.

[0039] The bottom ends of two springs 26 are fixedly connected to the inner walls of the front and rear ends of the rotating column 22, respectively. Fixing the springs 26 ensures that the force on them is even. Two fixed shafts 27 are fixedly connected to the top side of the sliding ring 23, causing the two fixed shafts 27 to slide synchronously during the sliding process. The two fixed shafts 27 are externally slidably connected to the interior of multiple circular holes 28, providing space for their engagement. Multiple circular holes 28 are provided on the bottom right end of the screening plate 9, allowing for adjustment. A rotating plate 29 is fixedly connected to the top side of the rotating column 22, causing the rotating plate 29 to rotate synchronously when the rotating column 22 rotates. The bottom side of the rotating plate 29 is slidably connected to the bottom inner wall of the screening plate 9, providing support for its rotation. A transmission rod 30 is fixedly connected to the top side of the rotating plate 29, causing it to rotate synchronously when the rotating plate 29 rotates. A sliding plate 31 is slidably connected to the outside of the transmission rod 30, and the position of the sliding plate 31 is adjusted by pushing the transmission rod 30. The sliding plate 31 is externally fixed to the right end of the misalignment plate 21, and the misalignment plate 21 restricts the sliding plate 31 so that it can slide stably.

[0040] Working principle: By placing the raw material inside the feeding frame 15, the motor 3 is started to drive the rotating shaft 4 to rotate, which in turn drives the drive wheel 32 to rotate, which in turn drives the driven wheel 19 to rotate via the belt 14, which in turn drives the driven shaft 16 to rotate, which in turn drives multiple separating plates 17 to rotate, so that the raw material can be equally distributed and fed to achieve a uniform feeding effect, thereby improving screening efficiency and thus improving product quality;

[0041] The raw material then falls onto the second screening plate 11, and the two rotating rings 5 ​​are driven to rotate by the rotating shaft 4. At the same time, the rotating rings 5 ​​are offset from the center of the rotating shaft 4, so that the rotating shaft 4 can drive the two contacting transmission columns 7 to slide up and down through the rotating rings 5, thereby driving the opening plate 8 to slide, and then driving the first screening plate 9 to slide. Through the connecting plate 10, the first screening plate 9 and the second screening plate 11 can slide up and down synchronously, thereby achieving the screening effect.

[0042] Then, according to the required size and grade of the raw material, a downward sliding force is applied by gripping the sliding ring 23, which in turn drives the two transmission blocks 24 to slide and compress the spring 26, allowing the spring 26 to store elastic potential energy. This then applies a force in the opposite direction to the sliding ring 23 to reset it. During the sliding process of the sliding ring 23, the fixed shaft 27 also slides. Then, the rotating column 22 is rotated, which drives the rotating plate 29 to rotate, thereby driving the transmission rod 30 to slide. Finally, the sliding plate 31 is slidably adjusted, thereby adjusting the misalignment of the screening plate 9 and the misalignment plate 21 to adjust the size of the overlapping aperture, thus improving the flexibility of the device. Then, the tension on the sliding ring 23 is released, and the reset force of the spring 26 is transmitted to the fixed shaft 27, which engages inside the round hole 28, thus completing the adjustment.

[0043] 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.
