There are many types of dry-mixed mortars, and the formula changes constantly according to needs.

[0003] The existing sand weighing mechanism for dry-mixed mortar production has the following problems: 1. Most of them use a suspended support scale, and the scale accuracy is easily affected by the rigidity of the support. 2. It is not convenient to mix and weigh sands of different coarseness and fineness, and the need to weigh them separately reduces work efficiency; 3. The dust removal effect is poor, and the dust generated during weighing and dropping cannot be effectively removed; therefore, there is room for improvement. Utility Model Content

The No. 1 bin 11, the No. 2 bin 12, and the No. 3 bin 13 are equidistantly installed on the top of the weighing box 2. The No. 1 bin 11, the No. 2 bin 12, and the No. 3 bin 13 are provided with a discharge pipe 14 with an electronic valve, and the discharge pipe 14 is connected to the weighing box 2. The weighing box 2 is fixed with an annular The first support plate 21, the weighing mechanism 3 is arranged in the weighing box 1, the weighing mechanism 3 is composed of a weighing bucket 31 and a weighing sensor 32, the upper end opening of the weighing bucket 31 is located below the discharge pipe 14, and the bottom of the weighing bucket 31 is provided with a discharge port 311 with an electronic valve, the weighing bucket 31 is fixedly installed with an annular second support plate 312 on the outside, the weighing sensor 32 is four, and is equidistantly installed between the first support plate 21 and the second support plate 312, and the weighing bucket 31 is balancedly installed in the weighing box 2.

[0021] Through the above technical scheme, in the dry-mixed mortar production line, the crushed raw sand is screened and divided into three types of sieves: coarse, medium and fine. Then the coarse sand is introduced into the No. 1 bin 11, the medium sand is introduced into the No. 2 bin 12, and the fine sand is introduced into the No. 3 bin 13. According to the needs of the production line, it is determined whether a single type of sand is weighed or a combination of multiple types of sand is weighed. When it is determined that a single type of sand is used, the electronic valve in the discharge pipe 14 below the sand bin of the corresponding type is opened as needed, so that the sand of this type enters the weighing bucket 31. The synchronous weighing sensor 32 weighs the sand entering the weighing bucket 31. When the required weight is reached, the electronic valve in the discharge pipe 14 is closed to stop conveying the sand into the weighing bucket 31. When multiple types of sand are needed for combined use, the corresponding types of sand bins open the electronic valves in the discharge pipe 14 below in turn, and the corresponding types of sand are sent into the weighing hopper 31 in turn. The weighing sensor 32 is used for superimposed measurement and weighing. After the required weight is reached, the electronic valve in the discharge pipe 14 is closed.
