[0002] A concrete batching plant, also known as a concrete precasting plant, is a mechanical equipment that uses machines to replace manual labor to mix materials such as cement, sand, gravel, and water in a certain proportion to produce concrete for construction projects and other operations, and then pumps it out. It is a combined unit used for centralized mixing of concrete. In a concrete batching plant, the feeding and batching of aggregates are key links. Traditionally, the feeding and batching process of aggregates mostly relies on manual operation, which is inefficient and prone to errors. In recent years, some automated feeding and batching systems have emerged, which have effectively improved the batching efficiency of concrete.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0032] This utility model provides, for example Figures 1 to 3 The illustrated automated feeding and batching system for recycled aggregates in a concrete mixing plant includes an aggregate bin 1, a first conveying pipe 2, a weighing module 3, a second conveying pipe 4, and a mixing tank 5. The inlet of the first conveying pipe 2 is fixedly connected to the outlet of the aggregate bin 1. The outlet of the first conveying pipe 2 is located on the upper side of the weighing module 3. The inlet of the second conveying pipe 4 is located on the lower side of the weighing module 3, and the outlet of the second conveying pipe 4 is located on the upper side of the inlet of the mixing tank 5. The weighing module 3 includes a collection box 31, a weighing hopper 32, a dust collection box 34, a screening plate 37, a screen 38, a sealing shell 39, a vibrator 311, and a dust collector 314. The weighing hopper 32 is located on the lower side of the collection box 31. A first valve 33 is installed in the outlet at the lower end of the weighing hopper 32, and a second valve 315 is installed in the outlet at the lower end of the collection box 31.
[0033] The system includes an aggregate bin 1 for storing concrete aggregates, a first conveying pipe 2 for conveying the concrete aggregates to a weighing module 3 for weighing the aggregates, a second conveying pipe 4 for conveying the weighed aggregates to a mixing tank 5 for mixing the aggregates, and a weighing hopper 32 in the weighing module 3 using a high-precision sensor to monitor the weight of the aggregates in real time and feed the monitored weight back to the control system. When a specified amount is reached, the control system automatically closes the second valve 315, stopping the material from the aggregate bin 31 from being fed into the weighing hopper 32. The control system incorporates machine learning algorithms to continuously optimize the batching ratio based on historical batching data and real-time monitoring data, improving the system's adaptability. Furthermore, the control system can interface with the mixing plant's ERP system to achieve real-time sharing and management of production data. A humidity sensor and particle size analyzer can be installed inside the aggregate bin 1 to monitor the humidity and particle size distribution of the recycled aggregates in real time. The control system adjusts the batching ratio based on the humidity and particle size data to improve batching accuracy.
[0034] During use, the control system starts the first conveying pipe 2, which conveys the concrete aggregate to the weighing module 3. The weighing module 3 screens and weighs the concrete aggregate. Once the specified weight is reached, the control system closes the first conveying pipe 2 and opens the second conveying pipe 4. The second conveying pipe 4 conveys the weighed material to the inside of the mixing tank 5, where the mixing tank 5 stirs and mixes the concrete aggregate.
[0035] See Figures 2 to 5The dust collection box 34 is fixedly connected to the left side surface of the collection box 31. A support frame 35 is fixedly connected to the upper surface of the dust collection box 34. The screen 38 is fixed to the surface of the screening plate 37. Multiple sets of support springs 36 are fixedly connected to the lower surface of the screening plate 37. The lower end of the support spring 36 is fixedly connected to the upper surface of the support frame 35. The sealing shell 39 is fixedly connected to the upper end of the screening plate 37. A feed trough 310 is opened on the left side of the upper surface of the sealing shell 39. The vibrator 311 is fixedly installed in the middle of the upper surface of the sealing shell 39. A dust collection box 312 is fixedly connected to the middle of the inner top wall of the sealing shell 39. A dust collection pipe 313 is fixedly connected to the upper surface of the dust collection box 312. A vacuum cleaner 314 is fixedly installed on the upper surface of the collection box 31. The upper end of the dust collection pipe 313 passes through the top wall of the sealing shell 39 and is fixedly connected to the dust collection port of the vacuum cleaner 314.
[0036] Specifically, during the weighing of concrete aggregate, the discharge port of the first conveying pipe 2 transports the concrete aggregate through the feed trough 310 to the surface of the screen 38. At this time, the control system starts the vibrator 311 and the dust collector 314. With the cooperation of the support spring 36, the vibrator 311 drives the sealing shell 39 and the screening plate 37 to vibrate. During the vibration, the sealing shell 39 blocks the concrete aggregate to prevent it from falling. At this time, small particles of aggregate and dust in the concrete aggregate leak down through the screen 38 into the interior of the dust collection box 34. The dust collection box 34 collects the small particles of aggregate and dust that have been screened out and recycles them.
[0037] Meanwhile, during the vibratory screening of concrete aggregates, some dust will be scattered inside the sealed shell 39. At this time, the dust will be sucked up by the vacuum cleaner 314 and the dust collection box 312 to prevent the dust from settling back onto the surface of the concrete aggregates, thereby further improving the accuracy of concrete aggregate weighing.
[0038] In addition, the screening plate 37 is inclined, which causes the concrete aggregate to move to the right during the vibration of the screening plate 37. The screened concrete aggregate is then transported into the collection box 31. At this time, the control system opens the second valve 315, allowing the screened concrete aggregate to be transported through the discharge port at the lower end of the collection box 31 to the weighing hopper 32. The weighing hopper 32 weighs the concrete aggregate in real time. When the concrete aggregate is close to the specified value, the control system will partially close the discharge port at the lower end of the collection box 31 through the second valve 315 to reduce the discharge of concrete aggregate. When the concrete aggregate reaches the specified value, the discharge port at the lower end of the collection box 31 will be completely closed through the second valve 315. At this time, the control system opens the first valve 33 at the lower end of the weighing hopper 32, discharging the concrete aggregate in the weighing hopper 32 into the inlet of the second conveying pipe 4. The second conveying pipe 4 then transports the concrete aggregate into the mixing tank 5 for stirring and mixing to prepare concrete.
[0039] The working principle of this utility model is as follows: The vibrator 311 drives the sealing shell 39 and the screening plate 37 to vibrate, thereby removing smaller aggregate particles and dust from the concrete aggregate, improving the purity of the concrete aggregate. Then, the screened concrete aggregate is discharged into the weighing hopper 32 for weighing, which effectively improves the weighing accuracy of the concrete aggregate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
