[0019] Example:
[0020] As attached Figure 1 and attached Figure 2As shown, an automatic weighing device for concrete additive production comprises a side mounting plate 1, support columns 2 are fixed at the four corners of the lower part of the side mounting plate 1, rotating drive rollers 3 are axially connected on the left and right sides of the inner part of the side mounting plate 1, positioning grooves 4 are respectively provided on the left and right sides of the inner part of the rotating drive roller 3, and a material conveyor belt 5 is sleeved on the outer side of the rotating drive roller 3, characterized in that a material storage and conveying box 6 is installed on the outer side of the material conveyor belt 5, and a supporting weighing partition 7 is installed at the middle position of the inner side of the side mounting plate 1; the material storage and conveying box 6 comprises an additive raw material storage box 61, and positioning protrusions 62 are respectively integrated at the four corners of the lower outer side of the additive raw material storage box 61, and a supporting connecting column 63 is fixed at the lower middle position of the additive raw material storage box 61, and a bottom limiting piece 64 is connected to the lower outer side of the supporting connecting column 63.
[0021] As attached Figure 3 As shown, in the above embodiment, specifically, the supporting weighing partition 7 includes a supporting transverse plate 71, and mounting grooves 72 are respectively opened on the left and right sides of the upper part of the supporting transverse plate 71, and weighing sensors 73 are respectively fixed on the left and right sides of the inner part of the supporting transverse plate 71, and a sliding protective plate 74 is placed on the upper part of the weighing sensor 73.
[0022] In the above embodiment, specifically, the supporting transverse plate 71 is fixed at the middle position of the inner side of the side mounting plate 1 , and the sliding protection plate 74 is inserted into the inner upper part of the mounting groove 72 .
[0023] In the above embodiment, specifically, the supporting transverse plate 71 is arranged on the inner side of the material conveyor belt 5 , and the rotating driving rollers 3 are respectively located on the left and right sides of the supporting transverse plate 71 .

[0025] How it works
[0026] The working principle of the utility model is as follows: before use, the device needs to be moved to the lower part of the discharge port of the raw material storage barrel, and the raw material flows out from the discharge port into the inner side of the additive raw material storage box 61. As the weight of the raw material increases, the downward pressure of the additive raw material storage box 61 also increases. The additive raw material storage box 61 transmits the pressure to the surface of the sliding protective plate 74 through the supporting connecting column 63. The sliding protective plate 74 applies downward pressure to the weighing sensor 73, thereby weighing the material inside the additive raw material storage box 61. After reaching the expected weight, the servo motor at the rear end of the side mounting plate 1 drives the rotating drive roller 3 to rotate, and drives the additive raw material storage box 61 to move to the left through the material conveyor belt 5. When the additive raw material storage box 61 filled with raw materials moves to the upper part of the weighing sensor 73 on the left, the raw materials inside the additive raw material storage box 61 can also be weighed for a second time to improve the accuracy.
[0027] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
