The transmission shaft 602 passes through the two sets of aggregate storage hoppers 3. Multiple stirring shafts 603 are fixedly connected to the outside of the transmission shaft 602. The multiple stirring shafts 603 are located inside the aggregate storage hopper 3.
[0032] By setting up the aggregate storage hopper 3, the weighing module 405 can quickly weigh the aggregate inside the hopper 3 during use. After the aggregate weight reaches the required level, the central controller 701 will activate the telescopic rod 406, and the gate 402 will rotate to pour the aggregate out of the hopper 3 into the top of the conveyor belt 101. Under the transmission of the conveyor belt 101, the aggregate is placed into the mixer, completing the aggregate metering and batching. This effectively controls the aggregate batching error during use, significantly improving the consistency of concrete strength; further improving production efficiency, while also enhancing the level of automation and effectively reducing manual intervention; the system has low operating costs and is suitable for small and medium-sized mixing plants. By setting up the mixing mechanism 6, during use, due to the shape and material of the aggregate, blockage may occur inside the aggregate storage hopper 3, which may affect the metering. The drive motor 601 can drive the transmission shaft 602 to make multiple sets of agitator shafts 603 mix, ensuring the stability of the aggregate during feeding and improving the practicality of the device.

A control panel 702 is installed on one side of the central controller 701, and the control panel 702 is electrically connected to the frame 1 and the gate weighing mechanism 4. By installing the photoelectric sensors 5, the aggregate flow rate at the top of the conveyor belt 101 can be further detected during use. Combined with multiple sets of aggregate storage hoppers 3, the aggregate measurement is more accurate, improving the practicality of the device.

[0035] Working Principle: By setting up aggregate storage hopper 3, the weighing module 405 can quickly weigh the aggregate inside the aggregate storage hopper 3 during use. After the aggregate weight reaches the required level, the central controller 701 will activate the telescopic rod 406, and the gate 402 will rotate to pour the aggregate inside the aggregate storage hopper 3 into the top of the conveyor belt 101. Under the conveyor belt 101, the aggregate is put into the mixer, completing the aggregate metering and batching. In use, this can effectively control the aggregate batching error, significantly improve the consistency of concrete strength, further improve production efficiency, and enhance the level of automation, effectively reducing manual intervention.

By setting up photoelectric sensor 5, the aggregate flow rate at the top of the conveyor belt 101 can be further detected during use. In conjunction with multiple sets of aggregate storage hoppers 3, the aggregate metering is more accurate, improving the practicality of the device.
[0036] Among them, by setting the stirring mechanism 6, during use, due to the shape and material of the aggregate, it may become blocked inside the aggregate storage hopper 3, which may have a certain impact on the amount of aggregate. The drive motor 601 can drive the transmission shaft 602 to make multiple sets of stirring shafts 603 stir, ensuring the stability of the aggregate during feeding and improving the practicality of the device. By setting the moving block 407, during use, the stabilizing plate 8 can make the movement of the gate 402 more stable, improving the stability of the device during use and improving the practicality of the device.
