[0002] Concrete, abbreviated as concrete, is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. Usually, multiple raw materials are mixed with water in a certain proportion to form concrete. It is widely used in civil engineering. Before mixing and stirring, the raw materials need to be measured and batched through a batching device to ensure the accuracy of the concrete production ratio.

[0003] The existing patent (publication number: CN220840913U) discloses a concrete batching machine with automatic metering, including a frame, a plurality of weighing hoppers are arranged on the frame, and pressure plates are symmetrically arranged on both sides of the plurality of weighing hoppers, a weighing sensor is arranged between the pressure plate and the frame, a discharge barrel is arranged at the bottom of the weighing hopper, a feeding conveyor is arranged at the bottom of the discharge barrel, the bottom end of the discharge barrel is arranged inside the dustproof component, and the dustproof component is arranged on the upper part of the feeding conveyor. The utility model provides a weighing sensor between both sides of the weighing hopper and the frame, and utilizes the weighing sensor to realize the function of automatic metering and batching of concrete raw materials, thereby improving the automated use of the device and improving production efficiency and accuracy; by arranging the feeding conveyor and the discharge barrel in the dustproof component, the diffusion of dust is reduced during the unloading and conveying of the raw materials in the weighing hopper, the dust pollution is reduced, and the environment and the health and safety of the workers are protected.

[0034] See also Figure 1 、 Figure 2 and Figure 3A weight sensor 6 is installed between the left side of each silo 2 and the support frame 1. Through the setting of the weight sensor 6, the purpose of monitoring the weight of the material inside the silo 2 can be achieved. The bottom of the support frame 1 is fixedly connected with a base plate 7, and the upper surface of the base plate 7 contacts a moving block 8. The top of the moving block 8 is fixedly connected with a moving frame 9. The upper surface of the base plate 7 is fixedly connected with two shaft seats 17, and a threaded rod 18 is rotatably connected between the two shaft seats 17.

The outer surface of the stirring shaft 11 is fixedly connected with a plurality of stirring blades 12.

[0035] See also Figure 1 、 Figure 2 and Figure 3 A first motor 19 is installed on the inner bottom wall of the movable frame 9, and the output end of the first motor 19 is fixedly connected to the bottom end of the stirring shaft 11.

Through the setting of the control host 21, the purpose of controlling the electrical components can be achieved.

[0036] In this embodiment, a dust prevention device for a concrete batching machine is provided. By providing a bellows 4 and a sealing disk 5 at the bottom of each discharge pipe 3, a complete seal of the discharge port is achieved, effectively preventing the direct diffusion of dust during the discharge process. At the same time, the electric push rod 16 drives the cover plate to close contact with the mixing tank 10, further enhancing the sealing effect, ensuring that dust does not leak from the sides or bottom of the device, and significantly improving the dust prevention performance. The weight sensor 6, electric valve 14, electric push rod 16, first motor 19, second motor 20 and other automated components are centrally controlled by the control host 21. This design not only improves batching accuracy and production efficiency, but also makes the entire batching and mixing process more intelligent and convenient, reduces manual intervention, and reduces operational difficulty and labor intensity. The silo wall vibrator 13 installed outside the silo 2 can effectively prevent material from clogging in the discharge pipe 3, ensuring smooth batching. At the same time, the design of the stirring shaft 11 and stirring blades 12 in the mixing tank 10 ensures that the concrete raw materials are fully and evenly mixed during the mixing process, thereby improving the quality of the concrete.

[0037] The working principle of the above embodiment is: the control host 21 starts the second motor 20 to drive the threaded rod 18 to rotate as needed, and drives the moving block 8 and the moving frame 9 to move along the bottom plate 7, so that the mixing tank 10 is located below the discharge pipe 3 that needs to be dosed. The control host 21 starts the electric push rod 16 to push the cover plate downward until it is in close contact with the mixing tank 10, forming a further seal to ensure that dust does not leak from the sides or bottom of the device. When the batching starts, the control host 21 controls the electric valve 14 under each silo 2 to open in turn according to the preset ratio, allowing the material to pass through the discharge pipe 3 into the bellows 4, and is sealed at the bottom by the sealing disk 5 to prevent dust from leaking. At the same time, the silo wall vibrator 13 outside the silo 2 is started to prevent the material from being blocked in the discharge pipe 3. The material falls smoothly into the mixing tank 10 through the bellows 4. The above process is repeated until all the raw materials are added to the mixing tank 10 according to the proportion. After the ingredients are mixed, the control host 21 starts the first motor 19 to drive the stirring shaft 11 and the stirring blade 12 to rotate in the mixing tank 10 to fully and evenly mix the concrete raw materials to improve the quality of the concrete. During the whole process, the control host 21 monitors the data of each weight sensor 6 in real time to ensure the accuracy of the ingredients. Through automatic control, manual intervention is reduced, and production efficiency and dust prevention performance are improved.
