Description
Technical Field
[0001] The utility model relates to the technical field of concrete sand and gravel equipment, in particular to a concrete sand and gravel mixing mixer. Background Art
[0002] Concrete sand and gravel are important components of concrete, mainly used to provide the skeleton of concrete and enhance the strength and stability of concrete. The following are some basic concepts and considerations about concrete sand and gravel:
[0003] Composition of concrete:
[0004] Concrete is mainly composed of cement, water, fine aggregate (such as sand) and coarse aggregate (such as crushed stone or gravel). In the mixing process of these four basic materials, sand and gravel play an irreplaceable role and have a decisive influence on the comprehensive performance of concrete.
[0005] The role of sand and gravel:
[0006] 1. Provide skeleton: Sand and gravel are skeleton materials in concrete, which can effectively bear and disperse the load applied to concrete and improve the compressive strength and durability of concrete.
[0007] 2. Reduce shrinkage cracks: Concrete may shrink during the hardening and drying process. The right amount of sand and gravel can effectively reduce cracks caused by shrinkage.
[0008] 3. Improve workability: Appropriate sand and gravel can improve the workability of concrete, making it easier to mix, transport and shape.
[0009] 4. Reduce costs: Sand and gravel are relatively economical materials, and their large-scale use in concrete helps to reduce overall costs.
[0010] Factors to consider when choosing sandstone:
[0011] 1. Particle size distribution: Sand and gravel with appropriate particle size distribution should be selected to ensure that the concrete has good density and workability.
[0012] 2. Cleanliness: Sand and gravel must be clean and free of dirt, organic matter and other impurities that will affect the setting and strength of concrete.
[0013] 3. Grain type: Smooth sand and gravel grain type improves the workability of concrete, while angular particles help improve the strength of concrete.
[0014] 4. Compressive strength: The selected sand and gravel should have sufficient compressive strength and durability to ensure the long-term stability of the concrete structure.
[0015] The quality of sand and gravel directly affects the performance of concrete. Therefore, when selecting sand and gravel, its quality standards must be strictly controlled to ensure that the strength, durability and working performance of the final concrete product meet the design requirements.
[0016] The application number is CN202320776425.6. The concrete sand and gravel mixer includes an equipment base, a rotating frame is provided on one side of the upper end of the equipment base, a connecting frame is provided in the middle of the upper end of the equipment base, a control cabinet is provided on the other side of the upper end of the equipment base, a sealing cover fixing mechanism is provided on the outer surface of one side of the rotating frame, a mixing and stirring barrel is provided on the inner wall of the rotating frame, and a sealing cover is provided in the middle of the upper end of the mixing and stirring barrel. This kind of building concrete sand and gravel mixer can limit and fix the position of the power cord through the power cord storage mechanism and the sealing cover fixing mechanism, but the equipment cannot ensure the mixing degree of the sand and gravel when mixing.

The angle formed by the inner side of the piercing rod is an acute angle, so that the stirring radius formed by the piercing rod when rotating is smaller than the stirring radius formed when the stirring blade rotates.
[0022] Furthermore, the stirring blade has a fan-shaped shape, so that a larger stirring radius is formed when the stirring blade rotates, so as to facilitate stirring of sand and gravel with a particle radius.
[0023] Furthermore, the thorn rod and the rotating rod are fixedly connected to prevent the thorn rod from falling off.
[0024] Furthermore, the thorn rod is made of a hard material to prevent the sand and gravel from being too hard and damaging the use of the thorn rod.
[0025] Furthermore, the screening structure includes a discharge hole and a diverter pipe. The bottom end of the guide pipe is provided with a diverter pipe, and the bottom end of the diverter pipe is provided with a discharge hole. The length of the diverter pipe is equal to the length of the mixing tank, so that the discharge hole can evenly guide the sand and gravel into the mixing range inside the mixing tank.
[0026] Furthermore, the inner side of the diverter pipe is in a truncated cone shape, which is convenient for the discharge of sand and gravel.
[0027] Compared with the prior art, the beneficial effects of the utility model are:
[0028] 1. The utility model drives the stirring blade and the thorn rod through the rotating rod, the rotating rod drives the sand and gravel with larger particles to stir, and the thorn rod is set to stir the sand and gravel in the next step, thus improving the mixing degree of the sand and gravel;

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] like Figure 1-Figure 2 As shown, a concrete sand and gravel mixing mixer comprises a mixing tank 1, a guide hopper 2 is arranged at one end of the top of the mixing tank 1, a power box 3 is arranged at one end of the mixing tank 1, and an auxiliary structure 6 is arranged transversely at one end of the power box 3;
[0038] A guide pipe 7 is provided at the bottom end of the guide hopper 2, a base frame 5 is provided at the lower end of the outer side of the mixing tank 1, a discharge box 4 is provided in the middle of the bottom end of the mixing tank 1, and a screening structure 8 is provided at the bottom end of the guide pipe 7.
[0039] like Figure 1-Figure 5 As shown, a concrete sand and gravel mixing mixer, the auxiliary structure 6 includes a stirring blade 601, a rotating rod 602 and a thorn rod 603, one end of the power box 3 is provided with a rotating rod 602, one end of the outer side of the rotating rod 602 is provided with a stirring blade 601, and the other end of the outer side of the rotating rod 602 is provided with a thorn rod 603. The angle formed by the inner side of the thorn rod 603 is an acute angle. The power box 3 drives the rotating rod 602 to rotate, and the rotating rod 602 drives the stirring blade 601 and the thorn rod 603 to rotate. The stirring radius of the rotating rod 602 is different from the stirring radius of the thorn rod 603. The rotating rod 602 and the thorn rod 603 mix the sand and gravel evenly, and the effects include:
[0040] 1. Improve mixing efficiency: The power box 3 drives the rotating rod 602 and the stirring blades 601 and the thorn rods 603 on the outside thereof to rotate, so that the sand and gravel in the concrete can be mixed more evenly and efficiently during the mixing process. The stirring blades 601 are used for large-scale, basic mixing, and the thorn rods 603 are designed to break up large pieces of material in the concrete or remove air bubbles, thereby ensuring the uniformity of the concrete.
[0041] 2. Optimize stirring power: The design of the rotating rod 602 enables the stirring blade 601 and the thorn rod 603 to have different stirring radii. Such a design helps to form different stirring intensities and ranges, and achieve more detailed and in-depth stirring. In particular, the sharp angle formed on the inner side of the thorn rod 603 can effectively cut and disperse the sand and gravel in the concrete, reduce the gaps in the concrete mixing process, and improve the density of the concrete.
[0042] 3. Improve the quality of concrete: Due to the combined effect of the stirring blade 601 and the thorn bar 603, the cement paste and sand and gravel can be mixed more thoroughly, avoiding material sedimentation and stratification, thereby producing concrete with higher quality and more uniform structure.
[0043] 4. Reduce the mixing time: This configuration of the auxiliary structure 6 improves the efficiency of the mixing process. Compared with the traditional mixing method, the mixing process can be completed in a shorter time, which is of great significance for improving production efficiency and reducing energy consumption and costs.
[0044] 5. Increased operational flexibility: This design increases the flexibility of adjusting for different concrete proportions and characteristics during the mixing process. For example, for concrete containing more large-size sand and gravel, the effect of the spike 603 can more significantly improve the quality of the concrete.
[0045] In summary, the design of the auxiliary structure 6 effectively improves the efficiency of concrete mixing and the quality of concrete products, and helps to meet the high requirements of modern buildings on concrete performance.
[0046] like Figure 1-Figure 5 As shown, a concrete sand and gravel mixing machine, the screening structure 8 includes a discharge hole 802 and a diverter pipe 801, the bottom end of the guide pipe 7 is provided with a diverter pipe 801, the bottom end of the diverter pipe 801 is provided with a discharge hole 802, the length of the diverter pipe 801 is equal to the length of the mixing tank 1, the guide pipe 7 guides the sand and gravel into the diverter pipe 801, at this time the diverter pipe 801 cooperates with the discharge hole 802 to evenly distribute the sand and gravel raw materials inside the mixing tank 1, wherein the design of the screening structure 8, especially the application of the discharge hole 802 and the diverter pipe 801 in the mixing tank 1, has the following important effects:
[0047] 1. Even distribution of sand and gravel raw materials: Through the cooperation of the discharge hole 802 and the diverter pipe 801, even distribution of sand and gravel raw materials can be achieved inside the mixing tank 1. This even distribution is critical to ensuring the quality of concrete because it helps to avoid material accumulation and stratification, ensuring that each part of the concrete has similar composition and quality.
[0048] 2. Improve mixing efficiency: When the sand and gravel are evenly distributed into the mixing tank 1 through the discharge hole 802, the stirring blades 601 and other mixing equipment can more effectively contact the concrete material, thereby improving the efficiency and effect of mixing. The uniform material distribution reduces the risk of uneven mixing and shortens the required mixing time.
[0049] 3. Reduce material waste: The precise discharging and diversion design helps to reduce material overflow or unnecessary waste that may occur during the mixing process. By accurately controlling the position and amount of sand and gravel entering the mixing tank 1, it can ensure that every portion of raw material used plays a role in production.
[0050] 4. Optimize the material loading process: The length of the diversion pipe 801 is equal to the length of the mixing tank 1, which means that the sand and gravel raw materials can be evenly distributed over the entire length of the mixing tank 1, which is not only beneficial for improving the mixing uniformity, but also helps to speed up the entire loading and mixing process and achieve an efficient production process.
[0051] 5. Improve concrete quality: Since sand, gravel and other raw materials can be evenly mixed, the final concrete product will have better structural uniformity and strength, which is especially important for meeting the requirements of high-performance concrete.
[0052] In general, the screening structure 8 improves the uniformity and efficiency of mixing by optimizing the distribution of sand and gravel raw materials in the mixing tank 1, which helps to produce higher quality concrete while improving production efficiency and reducing costs.
[0053] Working principle: When using the concrete sand and gravel mixing mixer, first transfer the raw materials into the mixing tank 1 through the guide hopper 2. At this time, the guide hopper 2 guides the sand and gravel into the guide pipe 7, and the guide pipe 7 guides the sand and gravel into the diversion pipe 801. At this time, the diversion pipe 801 cooperates with the discharge hole 802 to evenly distribute the sand and gravel raw materials inside the mixing tank 1. At the same time, the power box 3 drives the rotating rod 602 to rotate, and the rotating rod 602 drives the stirring blades 601 and the thorn rod 603 to rotate. The stirring radius of the rotating rod 602 is different from the stirring radius of the thorn rod 603. The rotating rod 602 and the thorn rod 603 mix the sand and gravel evenly, and finally the processed sand and gravel enter the discharge box 4. This is the working principle of the concrete sand and gravel mixing mixer.
[0054] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
