Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art all belong to the protection scope of the present invention.

The automatic weighing device for the concrete weighing as shown in fig. 1 comprises a first weighing device 1, a material bin 2 arranged above the first weighing device 1, a second weighing device 3 arranged below the material bin 2, a weighing hopper 4 arranged above the second weighing device 3, a receiving hopper 5 arranged below the weighing hopper 4, and a conveying pump 6 arranged at the bottom of the receiving hopper 5; a first electric valve 7 at the bottom of the material bin 2; a second electric valve 8 at the bottom of the weighing hopper 4; a first dustproof cloth 9 is arranged between the weighing hopper 4 and the material bin 2; and a second dustproof cloth 10 is arranged between the material receiving hopper 5 and the weighing hopper 4.

In the present embodiment, the first weighing apparatus 1 is composed of four columns and four high-precision electronic scales, and the high-precision electronic scales are disposed at the bottoms of the columns. When the first weighing device 1 is used, the material bin 2 is firstly empty, the four electronic scales are reset to zero, and when the material bin 2 is filled with materials, the sum of the displayed readings of the four electronic scales is the total weight of the materials in the material bin 2. When the materials in the material bin 2 are discharged through the first electric valve 7, the sum of the current four electronic scale readings is subtracted from the total weight, so that the weight of the discharged materials is obtained.

In this embodiment, the second weighing device 3 is also composed of four columns and four high-precision electronic scales, and the high-precision electronic scales are arranged at the bottoms of the columns. When the weighing hopper 4 is used, the weighing hopper 4 is empty, the four electronic scales are reset to zero, and when the weighing hopper 4 is filled with materials, the sum of the readings displayed by the four electronic scales is the weight of the materials in the weighing hopper 4. Judging whether the weight of the materials in the weighing hopper 4 meets the requirement or not according to the weight, if not, continuously discharging the materials from the material bin 2; if the weight of the materials exceeds the required weight, when the materials are discharged from the weighing hopper 4 and the sum of the readings of the four electronic scales is the weight of the redundant materials, the second electric valve 8 is closed, and the redundant materials are left in the weighing hopper 4.

In this embodiment, the first dustproof cloth 9 is hung at the bottom of the material bin 2, the lower part of the first dustproof cloth is connected to the upper edge of the weighing hopper 4, and the first dustproof cloth 9 covers the first electric valve 7 and the weighing hopper 4. The second dustproof cloth 10 is hung at the bottom of the weighing hopper 4, the lower part of the second dustproof cloth is connected to the upper edge of the material receiving hopper 5, and the second dustproof cloth 10 covers the second electric valve 8 and the upper part of the material receiving hopper 5. Such a setting can effectively avoid raising dust when using the device.

When the automatic weighing device for weighing the concrete is used, the total number of readings of the four electronic scales of the first weighing device 1 is recorded, the first electric valve 7 is opened, the material is discharged into the weighing hopper 4, and when the total number of readings of the electronic scales is reduced by the weight of the required material, the first electric valve 7 is closed. And then observing whether the readings of the four electronic scales of the second weighing device 3 meet the required weight, judging whether the weight meets the requirement, and further judging whether the materials need to be continuously added or whether redundant parts are left when the materials in the weighing hopper 4 are discharged into the receiving hopper 5. Finally, a transfer pump 6 at the bottom of the receiving hopper 5 sends the materials out to the blender. The proportion of each material in the concrete can be more accurate by using a double weighing mode, and redundant parts can be left when the materials 4 in the weighing hopper are excessive, so that the material waste is reduced. Meanwhile, due to the arrangement of the dustproof cloth, the dust is effectively reduced in the whole operation process, and the dustproof cloth has the characteristic of environmental protection.
