[0014] like Figures 1-3 As shown, the mixing device for building material testing includes a mixing tank 1, a rotating main shaft 10 is provided inside the mixing tank 1, blades 11 are fixed on both sides of the main shaft 10, the ends of the blades 11 are in close contact with the inner wall of the mixing tank 1, and a spiral blade 12 is fixed at the end of the main shaft 10, the spiral blade 12 is located at the discharge port 3 below the mixing tank 1. A top cover 4 is fixedly installed on the top of the mixing tank 1, and a motor 7 is fixedly installed in the middle of the top cover 4. The output shaft of the motor 7 is fixedly connected to the main shaft 10. The top cover 4 has multiple feed ports for material input. The raw materials for the insulation wall include various solid supports and liquid additives, which are added to the mixing tank 1 in proportion from their respective feed ports. The motor 7 drives the main shaft 10 to rotate, thereby causing the paddle 11 to mix the raw materials. The spiral blades 12 at the end of the main shaft 10 can also flip the raw materials that have settled at the bottom discharge port 3 to the top for mixing, greatly improving the efficiency and quality of mixing. After mixing is completed, the spiral blades 12 can be flipped to speed up the discharge of materials from the discharge port 3.

[0015] The mixing tank 1 contains a rotating main shaft 10, with blades 11 mounted on both sides of the main shaft. These blades will be close to the inner wall of the mixing tank during mixing to prevent the material from sticking to the inner wall and help ensure that the material is fully mixed.

[0016] The main shaft is equipped with a spiral blade 12 at the end, located at the discharge port 3 below the mixing tank. The spiral blades prevent material sedimentation and help the material circulate to the mixing area, while also assisting in the unloading process.

[0017] A motor 7 is mounted on the top of the upper cover 4, and the motor's output shaft is directly connected to the main shaft 10 to provide power for stirring. The upper cover also has multiple feed inlets for adding different types of solid supports and liquid additives. Various raw materials are added to the mixing tank through different feed inlets according to preset proportions. After the motor starts, the main shaft drives the impeller to rotate, ensuring thorough mixing of the materials. The spiral blades not only help improve mixing efficiency but also accelerate the material discharge process after mixing is complete.

[0018] Preferably, multiple support legs 2 are fixed to the bottom periphery of the mixing tank 1. These legs support the mixing tank 1, and the number of legs can be determined based on the size and weight of the mixing tank; common configurations include three-legged or four-legged supports. The legs are generally made of sturdy metal materials, such as steel or stainless steel, to ensure sufficient strength and durability. The legs can be upright or angled outwards, the latter contributing to increased overall stability. Adjustable-height legs are available to accommodate uneven terrain.

[0019] Preferably, the feed inlet includes a solid feed inlet 5 and a liquid feed inlet 6, which are located on both sides of the upper cover 4. Separating the solid and liquid feeds avoids mutual interference between materials, making feeding more convenient. Separating solids and liquids entering the mixing tank reduces cross-contamination between materials of different properties. Since solid and liquid materials have different characteristics, separate feeding facilitates more efficient initial mixing.

[0020] Ensure that solid and liquid raw materials are added in the correct order and proportion to achieve efficient mixing. In actual operation, the operator can add the solid support first through the solid inlet 5, and then add the liquid additive through the liquid inlet 6, according to the formulation requirements. This method allows for better control of the mixing process, ensuring the quality and performance of the final product.

[0021] Preferably, a water inlet pipe 8 is provided on one side of the top of the mixing tank 1, and a control valve is installed on the water inlet pipe 8. Water can be injected into the mixing tank through the water inlet pipe, which facilitates cleaning the inside of the mixing tank, especially important when changing different types of building material raw materials. If water needs to be added as a solvent or to adjust the flowability of materials during the mixing process, the water inlet pipe provides a simple and controllable method. The presence of the control valve allows the operator to precisely control the water volume, which is crucial for ensuring the consistency and quality of the mixture.

[0022] Preferably, a hinge seat is fixed on one side of the discharge port 3, and a rotating locking shaft 14 is provided on the other side. A cover plate 9 is provided at the discharge port 3. One side of the cover plate 9 is connected to the hinge seat via a pin 13, and the other side is connected to the locking shaft 14 via a nut 15. The cover plate 9 is opened by hinge and is connected to the locking shaft 14 via the nut 15 to abut against the discharge port 3, which facilitates the discharge of materials.

[0023] The cover plate 9 opens via a hinge, making operation simple and quick. The connection between the nut 15 and the locking shaft 14 ensures the stability of the cover plate 9 when closed, preventing accidental leakage of materials during mixing. The opening mechanism of the cover plate 9 also facilitates cleaning and maintenance of the discharge port 3.

[0024] Preferably, a sealing ring is provided between the cover plate 9 and the discharge port 3. The cover plate 9 presses against the sealing ring at the discharge port 3 to achieve a seal.

[0025] Preferably, the cover plate 9 has a notch on one side, the locking shaft 14 abuts against the notch, and the cover plate 9 is pressed against the discharge port 3 by the nut 15. The locking shaft 14 is hinged to one side of the discharge port 3. By rotating the locking shaft 14, it abuts against the notch on one side of the cover plate 9 and can be pressed by the nut 15, making installation and disassembly more convenient.

[0026] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
