Description

Technical Field

[0001] This utility model belongs to the field of mixing plant technology, specifically a vibrating screen for aggregate screening in mixing plants. Background Technology

[0002] In today's booming construction industry, concrete, as a fundamental building material, directly impacts the safety and durability of buildings. Aggregates, a key component of concrete, account for approximately 60%-80% of its total volume, and their quality plays a decisive role in concrete performance. High-quality aggregates require uniform particle size and reasonable gradation, making precise aggregate screening a core step in the batching plant's production process.

[0003] In the early stages of concrete mixing plants, manual or simple mechanical screening methods were commonly used in the aggregate screening process. Manual screening relies heavily on manpower, is inefficient, and its accuracy is greatly affected by human factors, making it difficult to meet the demands of large-scale, high-quality concrete production. For example, in large construction projects, the daily demand for concrete can reach thousands of cubic meters, and manual screening simply cannot supply standard-compliant aggregates in a timely manner. Simple mechanical screening equipment, such as simple drum screens, while improving screening efficiency to some extent, has many limitations. Its screening accuracy is limited, making it difficult to accurately grade aggregates, leading to unreasonable concrete gradation and affecting its strength and workability. Furthermore, drum screens are prone to clogging when processing wet or sticky aggregates, further reducing screening efficiency and increasing equipment maintenance costs.

[0004] Therefore, this utility model provides a vibrating screen for aggregate screening in a mixing plant. Utility Model Content

The top of the protective shell 3 is fixedly installed, and the top of the inner wall of the gantry frame 51 is fixedly installed with the dual-axis motor 52. Two sets of drive shafts 53 are provided, and the two sets of drive shafts 53 are fixedly installed on the output ends of the dual-axis motor 52 on both sides. The rotating component 6 includes concave wheels 61 and support shafts 62. Two sets of concave wheels 61 are provided, and the two sets of concave wheels 61 are fixedly installed on the end of the drive shaft 53 away from the dual-axis motor 52. The support shafts 62 are fixedly installed on both sides of the inner wall of the gantry frame 51, and the end of the support shaft 62 away from the gantry frame 51 is rotatably installed with the concave wheels 61. The impact component 7 includes a shaft frame 71 and an impact rod 72. Two sets of shaft frames 71 are provided, and the two sets of shaft frames 71 are fixedly installed on the gantry. The top of frame 51 is near both sides of the concave wheel 61. The inner wall of the shaft frame 71 is slidably installed with the impact rod 72. The limiting assembly 8 includes a guide cylinder 81 and a limiting plate 82. The guide cylinder 81 is fixedly installed on the side where the two sets of impact rods 72 are close to each other. The guide cylinder 81 is located in the groove of the concave wheel 61 and is slidably installed with the concave wheel 61. Two sets of limiting plates 82 are provided. The two sets of limiting plates 82 are fixedly installed on the surface of the impact rod 72. The shaft frame 71 is located on the side where the two sets of limiting plates 82 are close to each other. The adjusting mechanism 9 includes a fixing block 91, an electric push rod 92, a support frame 93, and a rubber block 94. The fixing block 91 is fixedly installed on the inner wall of the gantry frame 51. On both sides, the top of the fixed block 91 is fixedly installed with the electric push rod 92, and the output end of the electric push rod 92 is fixedly installed with the support frame 93. Two sets of rubber blocks 94 are provided, and the two sets of rubber blocks 94 are fixedly installed on both sides of the top of the support frame 93.

The collection box 103 is slidably installed with the base plate 1 through the slider 102 and the dovetail groove 101. The collection box 103 is located at the bottom of the screen 4.

[0026] like Figures 1 to 5As shown, the gantry frame 51 provides stable support for the dual-axis motor 52, enabling its safe operation. The cooperation between the dual-axis motor 52 and the drive shaft 53 drives the concave wheel 61 to rotate, ensuring its normal operation. The support shaft 62 provides support for the concave wheel 61, preventing it from wobbling during use. The concave wheel 61 rotates, allowing the guide cylinder 81 to move laterally along its groove. The cooperation between the shaft frame 71 and the impact rod 72 enables the guide cylinder 81 to impact the gantry frame 51 through its back-and-forth swing, generating high-frequency vibration to aid in the screening of the screen 4. The guide cylinder 81 enables the linkage between the impact rod 72 and the concave wheel 61, achieving rapid lateral movement. The limiting plate 82 can limit the impact rod 72 to prevent it from sliding out of the support range of the shaft frame 71 and causing the impact angle of the impact rod 72 to deviate. The cooperation between the fixing block 91 and the electric push rod 92 can push the support frame 93 to move upward. The cooperation between the support frame 93 and the rubber block 94 can move to the impact point of the impact rod 72 by the push of the electric push rod 92, thereby reducing the impact amplitude of the impact rod 72. The cooperation between the dovetail groove 101 and the slider 102 can make the collection box 103 quickly disassembled, and at the same time, the collection box 103 will not shake during use. The collection box 103 can collect and recycle the waste residue filtered by the screen 4 for easy disposal by the user.

[0027] Working Principle: During operation, the base plate 1 is first placed on a flat surface. Then, the user places the material on top of the screen 4. Subsequently, the dual-shaft motor 52 is started to drive two sets of drive shafts 53 to rotate. When the drive shafts 53 rotate, they drive the concave wheel 61 to rotate. When the concave wheel 61 rotates, the guide cylinder 81 slides in the groove of the concave wheel 61. As the concave wheel 61 rotates continuously, the guide cylinder 81 drives the impact rod 72 to move back and forth laterally. When the impact rod 72 moves, it continuously impacts the gantry frame 51, thereby generating vibration. When the concave wheel 61 rotates, the two sets of impact rods 72 can alternately impact the gantry frame 51, thereby achieving a high-frequency vibration effect. The gantry frame 51 transmits the vibration to the protective shell 3 and the screen 4. When the screen 4 exhibits high-frequency vibration, the material on its surface is fully filtered. After screening, the filtered waste falls into the collection box 103 for storage, while the finished product is continuously conveyed downwards due to vibration. When the vibration amplitude is too large and needs to be reduced, the electric push rod 92 is activated to push the support frame 93 upwards. When the support frame 93 moves upwards, it will drive the two sets of rubber blocks 94 to move. After moving, the rubber blocks 94 will come to one side of the impact rod 72, so that the impact rod 72 cannot directly hit the gantry frame 51. When the impact rod 72 hits the rubber block 94, the rubber block 94 itself has a certain degree of flexibility, which will reduce the impact amplitude of the impact rod 72 and reduce noise. Since the rubber block 94 also has a certain degree of hardness, the vibration can be generated and transmitted normally. After screening is completed, the user only needs to pull the collection box 103 to one side to process the waste.
