[0002] Concrete has high hardness, a wide range of raw material sources, and low cost. It is widely used in structures such as houses, roads, military projects, and nuclear power plants. Concrete is made of cement and fly ash in appropriate proportions. Before the concrete is prepared, the raw materials are generally stored in a silo. When it is needed, they are mixed in a reasonable proportion under strict control. Therefore, it is necessary to provide a concrete raw material feeding and metering device to weigh and measure the raw materials falling through the silo in real time, and to centrally transport the materials to ensure that the materials can be synchronously transported to the designated location for mixing and other processes.

[0004] Therefore, the purpose of the utility model is to provide a concrete raw material unloading metering device, in which the weighing sensor weighs and measures the raw materials falling through the silo in real time. When the weight of the material in the receiving silo reaches the preset weight, the solenoid valve controls the material guide pipe to close. When the materials in multiple receiving silos meet the preset value, the driving motor drives the support plate to rotate from the discharge silo, dumping the material onto the bottom conveyor belt for centralized transportation, ensuring that each material can be synchronously transported to the designated position for mixing and stirring and other processes.

[0029] The utility model provides a concrete raw material feeding metering device, please refer to Figure 1-6 , including a connecting frame 100, a weighing and unloading component 200 and an anti-blocking component 300;

[0030] Please continue reading Figure 1 , Figure 2 , Figure 5 and Figure 6 A connecting frame 100 is used as a connecting frame, and a plurality of groups of silos 110 are connected inside the connecting frame 100. A material guide pipe 120 is connected to the bottom of the silo 110. A solenoid valve 121 for controlling the opening and closing state of the material guide pipe 120 is connected to the material guide pipe 120. A material discharge silo 130 is connected to the bottom of the material guide pipe 120;

[0031] Please continue reading Figure 2 , Figure 3 , Figure 5 and Figure 6 The weighing and unloading component 200 is connected to the discharge bin 130 to weigh and measure the raw materials dropped into the bin 110;

[0032] The weighing and unloading component 200 includes a driving motor 210 threadedly connected to the outside of the discharge bin 130, the output end of the driving motor 210 extends into the discharge bin 130, the output end of the driving motor 210 is connected to a connecting rod 211, the outside of the connecting rod 211 is connected to a support plate 212, and drives the support plate 212 to rotate from the discharge bin 130, a weighing sensor 221 is threadedly connected to the support plate 212, and a bearing plate 220 for receiving the raw materials falling into the weighing sensor 221 is screwed on the top;

[0033] Weighing and unloading action:

[0034] The weighing sensor 221 cooperates with the load-bearing plate 220 to weigh and measure the raw materials falling through the silo 110 in real time. When the weight of the materials in the receiving silo 130 reaches the preset weight, the solenoid valve 121 controls the material guide pipe 120 to close (the preset value can be set to a data lower than the required material weight, because when the material guide pipe is closed, some raw materials will still fall under the action of gravity, which is set according to the real-time situation);

[0035] When the materials in the multiple receiving bins 130 meet the preset value, the driving motor 210 works to drive the support plate 212 to rotate from the discharge bin 130, and the materials are dumped onto the bottom conveyor belt for centralized transportation;

[0036] Please continue reading Figure 1 and Figure 4 In order to prevent the raw materials from being blocked during the unloading process of the silo 110, an anti-blocking component 300 for stirring the raw materials inside the silo 110 is connected to the connecting frame 100. The anti-blocking component 300 includes a stirring motor 310 threadedly connected to the outside of the connecting frame 100. The output end of the stirring motor 310 is connected to a shaft 311. The shaft 311 extends into multiple silos 110. A multi-component material plate 320 is welded on the shaft 311. The multi-component material plates 320 are arranged in a circular shape with equal distances along the outside of the shaft 311 with the axis of the shaft 311 as the center of the circle, and the material dividing plates 320 are arranged corresponding to the inside of the silo 110.

[0037] Anti-blocking action:

[0038] The stirring motor 310 works, driving the stirring member composed of the shaft 311 and the material distribution plate 320 to rotate, stirring the material in the silo 110 in real time, preventing the raw materials from agglomerating and blocking the material discharge port during the material discharge process, thereby increasing the smoothness of the material feeding.

[0039] Working principle: When the utility model is in use, the weighing sensor 221 cooperates with the load-bearing plate 220 to weigh and measure the raw materials falling through the silo 110 in real time. When the weight of the material in the receiving silo 130 reaches the preset weight, the solenoid valve 121 controls the material guide pipe 120 to close. When the materials in multiple receiving silos 130 meet the preset value, the driving motor 210 works to drive the support plate 212 to rotate from the discharge silo 130, and dump the material onto the bottom conveyor belt for centralized transportation. At the same time, the stirring motor 310 is set to work, driving the stirring element composed of the shaft 311 and the dividing plate 320 to rotate, and the material in the silo 110 is stirred in real time to prevent the raw material from agglomerating and blocking the material outlet during the material dropping process, thereby increasing the smoothness of the material feeding.

[0040] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
