[0020] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0022] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0023] Combination Figure 1-6 As shown, the batching equipment for the mineral admixture includes a frame 1, on which a batching box 2 is mounted. The top of the batching box 2 is an inlet, and the bottom is an outlet. A top cover 3 is provided on the inlet, and an outlet door 4 is provided on the outlet. An opening assembly for controlling the opening of the outlet door is provided on the side wall of the batching box 2. A pair of left and right adding boxes 5 are mounted on the frame 1, and the outlets of the adding boxes 5 are connected to the batching box 2. A batching and mixing mechanism is provided inside the batching box 2. The batching and mixing mechanism includes a pair of square shafts 6 rotatably mounted inside the batching box 2. The square shaft 6 is equipped with multiple stirring components. Each stirring component includes a fixed base 8, a stirring arm 9 on the fixed base 8, and a stirring paddle 10 on the stirring arm 9. Both the stirring arm 9 and the stirring paddle 10 have oval grooves 11. Adjusting bolts (not shown in the figure) are inserted into the two oval grooves 11 and locked in place. The stirring paddle 10 has a shallow groove 12. The shallow groove 12 and the back of the stirring arm 9 form two toothed surfaces 13, which mesh with each other. The side wall of the batching box 2 is also equipped with a batching motor 14 for driving the square shaft to rotate.

[0024] In the field of engineering materials, the rational use of mineral admixtures is of great significance for improving concrete performance and reducing production costs. This batching equipment includes a frame, within which a batching bin is installed. Addition bins are located on the frame and on both the left and right sides of the batching bin, with their outlets connected to the batching bin.

[0025] In actual production, chemical admixtures are placed in the left material bin, and solid mineral admixtures are placed in the right material bin. When using this equipment for batching, cement is first poured in through the inlet, the equipment is turned on, and the chemical admixtures and solid mineral admixtures flow into the batching bins in quantitative amounts according to the mixing ratio requirements. Simultaneously, the batching and mixing mechanism thoroughly mixes the cement, solid mineral admixtures, and chemical admixtures together. After the three are fully mixed, the feeding from the addition bin to the batching bins stops, and the uniformly mixed mineral admixtures are discharged from the outlet to enter subsequent production stages.

[0026] In this equipment, the mixing mechanism includes a pair of square shafts, on which multiple stirring components are mounted. When the mixing mechanism is used to mix the materials in the mixing tank, two mixing motors work simultaneously, and the two square shafts rotate accordingly, causing the stirring components to mix the materials.

[0027] like Figure 4-6The stirring assembly includes a stirring arm mounted on a fixed base, and a stirring paddle mounted on the stirring arm. In practice, the installation position of the stirring paddle on the stirring arm can be fine-tuned. To fine-tune the installation position of the stirring paddle, first loosen the adjusting bolt, then adjust the installation position of the stirring paddle. After determining the installation position of the stirring paddle, the inner and outer toothed surfaces re-engage, and finally tighten the adjusting bolt. The shallow groove of the stirring paddle and the back of the stirring arm each have inner and outer toothed surfaces. After the stirring paddle is installed, the inner and outer toothed surfaces are in an engaged state, allowing for a more stable and reliable installation of the stirring paddle.

[0028] As a specific structure, such as Figure 4-5 The fixing base 8 includes a pair of L-shaped bases 81, with a pair of upper and lower lugs 82 formed on the bases 81. Locking nuts are inserted into the corresponding lugs 82 and locked in place. In this structure, the fixing base includes a pair of L-shaped bases, which are fixed to the square post by locking nuts. In practice, the fixing base can be removed from the square post by simply unscrewing the two locking nuts; the entire disassembly method is relatively simple and quick.

[0029] like Figure 1-3 The outlet of the left addition box 5 is connected to a feeding pipe 15 via a control valve 16. The end of the feeding pipe 15 is fixed inside the batching box. The outlet of the right addition box 5 is connected to a screw feeder 17. The end of the screw feeder 17 is fixed inside the batching box. The feeding pipe 15 has multiple feeding ports.

[0030] In actual production, the left material bin contains chemical additives, and the right material bin contains solid mineral admixtures. During the batching process, the flow rate of the chemical additives can be adjusted via a control valve, and the chemical additives are delivered to the batching bins via a feeding pipe. Simultaneously, a screw feeder stably transports the solid admixtures from the right material bin to the batching bins, realizing the conveying and addition of multiple materials.

[0031] In addition, the feeding port is equipped with a discharge pipe 18, and the side wall of the discharge pipe 18 is provided with an inverted V-shaped guide block 19, which is positioned directly opposite the bottom opening of the discharge pipe. The feeding pipe has multiple feeding ports, each with a discharge pipe, and the bottom opening of the discharge pipe is provided with an inverted V-shaped guide block. When adding chemical additives, the guide blocks ensure that the chemical additives are evenly dispersed into the mixing tank.

[0032] In this structure, such as Figure 2 The discharge gate 4 is rotatably mounted at the discharge port via a pair of left and right rotating shafts 20. The rotating shafts extend out of the batching box and are equipped with an arc-shaped plate 21. The opening assembly includes an opening cylinder 22, the drive shaft of which is rotatably connected to the tail of the arc-shaped plate 21. In this structure, the opening and closing of the discharge gate can be controlled by the extension and retraction of the opening cylinder, achieving precise discharge control.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
