[0033] As attached Figure 1 To be continued Figure 4 As shown:

[0034] This utility model provides an automatic metering and adding system for concrete admixtures, including a storage unit 1, comprising at least one admixture storage tank 101. A partition 102 is provided inside the admixture storage tank 101, dividing it into a storage chamber 103 and a discharge chamber 104. The discharge chamber 104 is located below the storage chamber 103. Multiple baffles 105 are provided on the partition 102, dividing the storage chamber 103 into multiple storage cavities for storing different admixtures, such as a water-reducing agent storage cavity and an air-entraining agent storage cavity. Each storage cavity has a discharge port 106 in the area corresponding to the partition 102, allowing the admixture to fall from the storage cavity into the discharge chamber 104.

[0035] An admixture storage tank 101 has a viewing window 6 on its side wall, with transparent glass covering it. Operators can visually observe the remaining amount of admixture inside and outside the tank through the viewing window 6, facilitating timely replenishment. Furthermore, an agitator 7 is installed at the bottom of the admixture storage tank 101. This agitator 7 is driven by a motor, which rotates the agitator blades to stir the admixture, preventing sedimentation or clumping and ensuring the uniformity of the admixture's quality. Simultaneously, an electric heater 8 is installed at the lower part of the admixture storage tank 101. When the ambient temperature is low, the electric heater 8 can be turned on to heat the admixture, ensuring good fluidity.

[0036] It also includes an opening and closing unit 2, which includes multiple opening and closing components 201. Each opening and closing component 201 includes a sliding plate 2011 slidably disposed within the partition 102.

The admixture storage tank 101 is provided with an adjustment component 202 for adjusting the through hole 2012 to correspond to or be offset from the discharge port 106. The adjustment component 202 includes a connecting rod 2021 disposed on the sliding plate 2011 and a mounting plate 2022 mounted on the admixture storage tank 101.

[0037] When in use, the cylinder 2023 can be activated. The activation of the cylinder 2023 will drive the connecting rod 2021 to move, thereby driving the sliding plate 2011 connected to the connecting rod 2021 to move, so that the through hole 2012 and the discharge port 106 are misaligned. When they are aligned, the additive can fall from the discharge port 106 into the discharge chamber 104. When the through hole 2012 and the discharge port 106 are misaligned, the discharge port 106 is closed.

[0038] It also includes a metering unit 3, which includes a metering cylinder 301 and an electronic scale 302. The metering cylinder 301 is connected to a feed pipe 303 that communicates with its interior. The end of the feed pipe 303 away from the metering cylinder 301 is connected to the discharge chamber 104. A switch valve 304 is provided at the connection position between the feed pipe 303 and the discharge chamber 104. In use, the switch valve 304 is opened, and the liquid in the discharge chamber 104 will enter the metering cylinder 301. It should be noted that the height of the metering cylinder 301 is lower than that of the discharge chamber 104 to facilitate the flow of liquid. The metering cylinder 301 is mounted on the electronic scale 302 for accurately measuring the weight of the additives inside and outside the metering cylinder 301.

[0039] It also includes a liquid delivery pump 4. The bottom of the metering cylinder 301 is connected to a first pipe 401 that is connected to the inlet of the liquid delivery pump 4. A liquid discharge solenoid valve 402 is installed on the first pipe 401. The outlet of the liquid delivery pump 4 is connected to the concrete mixer through a second pipe 403.

[0040] When in use, when the liquid in the measuring cylinder 301 reaches the specified weight, the liquid discharge solenoid valve 402 can be opened, and then the liquid in the measuring cylinder 301 can be pumped into the concrete mixer.

[0041] The system also includes a control unit 5, which comprises a mounting box 501. The mounting box 501 houses a processor 502, a relay 503, and a display and operation module 504. The output of the electronic scale 302 is electrically connected to the input of the processor 502, and the output of the processor 502 is electrically connected to the input of the relay 503. The output of the relay 503 is electrically connected to the cylinder 2023, the liquid delivery pump 4, the switching valve 304, and the liquid outlet solenoid valve 402. The display and operation module 504 is electrically connected to the processor 502 and is used to set metering parameters and display metering information, such as the amount of admixture added and the addition time. The display and operation module 504 can also display metering information, such as the current weight of the admixture inside the metering cylinder 301 and the total amount of admixture added. Furthermore, the control unit 5 includes a wireless connector, which is electrically connected to the processor 502 and can wirelessly connect to a terminal display device for remote monitoring and control.
