Description

Technical Field

[0001] The present invention relates to the technical field of concrete mix design, and particularly to a new type of concrete mix design device and mix design method. Background Art

[0002] In the booming process of the modern construction industry, concrete has become an indispensable core building material in infrastructure construction, high-rise buildings, bridge projects and other fields due to its many advantages such as high strength, strong plasticity, and good durability. From the rise of urban landmark buildings to the completion of bridges and tunnels in the transportation network, concrete plays a crucial role. The quality of concrete not only directly determines the structural strength of buildings, affects whether buildings can withstand natural disasters such as earthquakes and strong winds, but also has a profound impact on the durability of buildings, determining the service life and maintenance cost of buildings. At the same time, the construction performance of concrete also directly affects the project progress and construction quality. For example, whether its workability is good or not will directly affect whether the concrete can be poured smoothly and vibrated densely. The concrete mix design process is a key link in determining its quality and performance. A scientific and reasonable mix design can accurately control key performance indicators such as the strength grade, setting time, and impermeability of concrete, enabling it to meet the construction performance requirements of different projects, optimize the use of raw materials, reduce production costs, achieve the optimal balance between cost and performance, and thus promote the sustainable development of the construction industry. Therefore, a new type of concrete mix design device is designed.

[0003] Currently, in terms of precise mix design of common concrete mix design devices on the market, existing devices often lack an accurate mixing structure adjustment system, making it difficult to adjust the position of mixing components according to different material mix requirements, unable to provide a suitable layout for concrete mixing, affecting the mixing effect and mix design accuracy. At the same time, the control of water and material addition is not precise enough, and problems such as insufficient mixing and local segregation of materials are likely to occur during the mixing process. Especially for some concretes with complex mix designs and high requirements for uniformity, traditional mixing methods are difficult to meet their quality requirements, resulting in impacts on the performance such as the strength and durability of concrete.

[0014] The invention discloses a novel concrete proportioning device and a proportioning method, comprising the following steps:

[0015] 1) A crushing bin is installed on each of the two cover plates on the mixing bin. Different types of bulk materials are put into the corresponding crushing bins through two feed hoppers. Two fifth motors are started at the same time to drive the crushing rollers in the crushing bins to crush the materials. The feeding speeds of the two feed hoppers are controlled by adjusting the chutes on the two baffle plates, so that different raw materials are crushed to appropriate particle sizes. At the same time, the external water supply equipment is turned on to transport water to the connecting pipe through a hose.

[0016] 2) Start the second motor, drive the screw to rotate through the worm gearbox, move the movable seat on the rail rod, adjust the position of the support rod to meet the requirements of different material ratios, and run the third motor to rotate the connecting plate on its output shaft.

[0019] The present invention provides a novel concrete proportioning device and proportioning method, which have the following beneficial effects:

[0020] In the present invention, in the precise proportioning stage, the second motor drives the lead screw to rotate through the worm gear box, which can accurately adjust the position of the movable seat on the rail rod, thereby changing the position of the support rod, and providing an adaptive mixing structure layout for different material proportions.

By controlling the valves of each feed port, the different materials crushed by the two crushing bins can be put into the mixing bin body strictly according to the proportion, which ensures the accuracy of the concrete proportion from multiple dimensions and ensures the stable and reliable quality of the finished product.

[0021] In addition, in the present invention, the first motor accurately drives the second rotating rod to rotate through a transmission mechanism composed of a pulley and a connecting belt, thereby driving the round rod, the stirring rod and the stirring frame to operate in coordination. During operation, the sprocket on the round rod is linked with the sprocket of the stirring frame with the help of a chain, giving the stirring frame the characteristic of independent rotation, and together with the stirring rod, a three-dimensional composite stirring mode is constructed, breaking the limitations of traditional single stirring, allowing the concrete raw materials to achieve multi-dimensional tumbling, shearing and fusion in the mixing bin, effectively avoiding local stirring dead corners and material segregation problems, greatly improving the uniformity and density of concrete mixing, and providing reliable guarantee for high-quality finished product output.

[0022] In addition, two crushing bins are provided in the present invention, which correspond to the two cover plates on the mixing bin respectively, and different kinds of bulk materials can be crushed at the same time. In the raw material pretreatment stage of the proportioning method, the crushing rollers in the respective crushing bins are driven by two fifth motors respectively, and the feed speed and crushing degree of different raw materials are flexibly controlled in conjunction with the adjustable baffle plate on the feed hopper, which not only avoids insufficient crushing caused by too fast feeding, but also solves the problem of low production efficiency caused by too slow feeding, thereby significantly improving the efficiency and pertinence of raw material pretreatment, laying a solid foundation for subsequent precise proportioning and high-quality concrete production, meeting diverse raw material processing needs, and effectively improving the efficiency and pertinence of raw material pretreatment.
