Abstract
Description
Technical Field
[0001] This utility model belongs to the field of engineering equipment, and specifically relates to a construction engineering mixer with a material premixing structure. Background Technology
[0002] Construction mixers are mechanical devices used in construction processes to mix various building materials (such as cement, sand, gravel, water, and additives). While some common construction mixers on the market are widely used in the construction industry, they still have certain limitations. During the mixing process, it is difficult for different materials to quickly achieve a uniform mixture. Taking concrete mixing as an example, cement, sand, gravel, and admixtures have different properties. Cement powder is light, while sand and gravel particles are large and heavy. When directly added to the mixing drum, gravity easily causes cement to float and sand and gravel to settle, resulting in uneven initial mixing.
[0003] Conventional methods often rely on extending the mixing time, hoping that the continuous rotation of the mixing drum and the repeated tumbling of the mixing blades will gradually promote uniform mixing of the materials. However, this method has obvious drawbacks. On the one hand, extending the mixing time will significantly reduce production efficiency, potentially delaying construction progress and increasing labor and time costs in tight construction projects. On the other hand, prolonged high-intensity mixing causes significant wear and tear on the equipment, accelerating the wear of components such as mixing blades and transmission devices. This not only shortens the equipment's lifespan but also increases the economic burden due to frequent maintenance and parts replacement. Therefore, a new structure is needed to solve the above-mentioned technical problems. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a construction engineering mixer with a material premixing structure to solve the problems mentioned in the background technology.
[0005] This utility model is achieved through the following technical solution: a construction engineering mixer with a material premixing structure, comprising: a premixing component and a stirring component, wherein a premixing component for premixing materials is installed on the outer surface of the stirring component, the premixing component includes a premixing tank for holding materials, a support is installed on the outer surface of the premixing tank, a transmission component is installed on the outer surface of the premixing tank, a stirring component one is installed inside the premixing tank, and the stirring component includes a stirring tank for fine mixing of materials, a stirring component two is installed inside the stirring tank.
[0006] In a preferred embodiment, four support legs are installed on the outer surface of the mixing tank, a sampling tube is installed at the lower edge of the outer surface of the mixing tank through a valve, and a discharge pipe is installed at the center of the lower surface of the mixing tank through a valve.
[0007] In a preferred embodiment, the second stirring component includes a mounting cover, a stirring motor, an injection pipe, a rotating shaft, and a stirring rod. The mounting cover is installed at the center of the upper surface of the stirring tank, and the injection pipe is installed on the upper surface of the mounting cover through a valve.
[0008] In a preferred embodiment, a stirring motor is installed at the center of the upper surface of the mounting cover. The output shaft of the stirring motor passes through the mounting cover and is connected to the rotating shaft. Two sets of stirring rods are installed on the outer surface of the rotating shaft. The two sets of stirring rods have the same structure. During use, the stirring component two finely mixes the materials inside the mixing tank. In construction engineering, materials such as concrete are prone to local enrichment if they are not finely mixed, which will lead to uneven concrete quality. At this time, the inclined stirring rods with a cross-shaped structure in the stirring component two can make the materials fully turn over and collide in the mixing tank, ensuring that the various components are evenly distributed in the mixture.
[0009] In a preferred embodiment, a cover plate is hinged to the left side surface and the right edge of the mounting cover, a handle is installed on the upper surface of the cover plate, and a sealing ring is provided at the contact point between the cover plate and the mixing tank.
[0010] In a preferred embodiment, the outer surface of the mixing tank is supported by a bracket via support legs, and a premixing tank is rotatably mounted between the brackets. The upper surface of the premixing tank is designed to be open.
[0011] In a preferred embodiment, a discharge plate is installed on the right edge of the premix tank opening, and a transmission component for connecting to a drive motor is installed on the left side surface of the premix tank.
[0012] In a preferred embodiment, a stirring element is rotatably mounted inside the premixing tank via a transmission component. Two sets of premixing components are provided, located on the left and right sides of the mixing tank. During use, the stirring element in the premixing tank can initially mix these materials during the premixing stage. Through stirring, materials of different densities and particle sizes can be initially mixed evenly, avoiding excessive differences in local components during subsequent fine mixing, and making them initially more evenly distributed.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting a mixing assembly, which includes a mixing tank for fine mixing of materials, and a second mixing component installed inside the mixing tank, the second mixing component finely mixes the materials inside the mixing tank during use. In construction engineering, materials such as concrete, if not finely mixed, these components are prone to local enrichment, which will lead to uneven concrete quality. At this time, the inclined mixing rod with a cross-shaped structure in the second mixing component can make the materials fully turn over and collide in the mixing tank, ensuring that various components are evenly distributed in the mixture, thereby improving the quality of building materials such as concrete and making the building structure more stable.
[0014] By setting up a premixing component, a premixing component for premixing materials is installed on the outer surface of the mixing component. The premixing component includes a premixing tank for holding materials, a transmission component installed on the outer surface of the premixing tank, and a mixing component installed inside the premixing tank. In construction engineering, the material composition is relatively complex. For example, concrete contains cement, sand, gravel, admixtures, and other components. The mixing component in the premixing tank can perform preliminary mixing of these materials during the premixing stage. Through stirring, materials with different densities and particle sizes can be initially mixed evenly, avoiding excessive differences in local composition during subsequent fine mixing, and making them initially more evenly distributed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 3 This utility model provides a technical solution: a construction engineering mixer with a material premixing structure, comprising: a premixing component 100 and a mixing component. The outer surface of the mixing component is equipped with a premixing component 100 for premixing materials. The premixing component 100 includes a premixing tank 110 for holding materials. A support is installed on the outer surface of the premixing tank 110. A transmission component 130 is installed on the outer surface of the premixing tank 110. A mixing component 140 is installed inside the premixing tank 110. The mixing component includes a mixing tank 200 for fine mixing of materials. A mixing component 300 is installed inside the mixing tank 200.
[0024] Please see Figures 1 to 3 As the first embodiment of this utility model: four support legs 210 are installed on the outer surface of the mixing tank 200, a sampling tube 220 is installed on the lower edge of the outer surface of the mixing tank 200 through a valve, and a discharge pipe is installed at the center of the lower surface of the mixing tank 200 through a valve.
[0025] The mixing component 300 includes a mounting cover 310, a mixing motor 330, an injection unit, a rotating shaft 340, and a mixing rod 350. The mounting cover 310 is installed at the center of the upper surface of the mixing tank 200, and an injection pipe 320 is installed on the upper surface of the mounting cover 310 through a valve.
[0026] A stirring motor 330 is installed at the center of the upper surface of the mounting cover 310. The output shaft of the stirring motor 330 passes through the mounting cover 310 and is connected to the rotating shaft 340. Two sets of stirring rods 350 are installed on the outer surface of the rotating shaft 340. The two sets of stirring rods 350 have the same structure.
[0027] A cover plate is hinged to the left side surface and the right edge of the cover 310. A handle is installed on the upper surface of the cover plate, and a sealing ring is provided at the contact point between the cover plate and the mixing tank 200.
[0028] When using the equipment, the user first prepares the materials to be mixed, and then premixes them through the premixing tank 110 in the premixing component 100 (the specific premixing speed and time need to be selected according to the actual situation, which will not be elaborated here). After premixing, the user can open the cover plate on the upper surface of the mixing tank 200 to allow the premixed materials in the premixing component 100 to be put into the mixing tank 200 for fine mixing. After the materials enter the mixing tank 200 and the water source for mixing is injected through the injection pipe 320, the user can start the stirring motor 330 on the upper surface of the mounting cover 310, causing the output shaft of the stirring motor 330 to rotate, thereby causing the stirring rod 350 on the outer surface of the rotating shaft 340 to stir the materials inside the mixing tank 200. Since the stirring rod 350 has a cross-shaped structure and is set at a 45-degree angle outside the rotating shaft 340, it can be used to stir the materials inside the mixing tank 200. Due to its special inclination angle and structure, the side surface of the mixing element 300 allows for fine mixing of materials inside the mixing tank 200. In construction engineering, materials like concrete, without fine mixing, can easily lead to localized enrichment of these components, resulting in uneven concrete quality. The cross-shaped, inclined mixing rod 350 in the mixing element 300 ensures that the materials are fully agitated and collided within the mixing tank 200, guaranteeing a uniform distribution of various components in the mixture. This improves the quality of building materials like concrete, making the building structure more stable. During mixing, the user can use the sampling tube 220 to discharge and inspect the materials inside the mixing tank 200. After mixing is complete, the user can open the discharge pipe on the lower surface of the mixing tank 200. (In actual use, the diameters of the discharge pipe and sampling tube 220 need to be matched according to the materials being mixed to avoid blockage during material discharge due to a smaller pipe diameter.)
[0029] Please see Figures 1 to 3 As a second embodiment of the present invention: a bracket is installed on the outer surface of the mixing tank 200 via a support leg 210, and a premixing tank 110 is rotatably installed between the brackets. The upper surface of the premixing tank 110 is designed to be open.
[0030] A discharge plate 120 is installed on the right edge of the opening of the premix tank 110, and a transmission component 130 for connecting to a drive motor is installed on the left side surface of the premix tank 110.
[0031] Inside the premixing tank 110, a stirring component 140 is rotatably mounted via a transmission component 130. Two sets of premixing components 100 are provided, and the premixing components 100 are located on the left and right sides of the mixing tank 200.
[0032] When using the material premixing process according to the operation steps of the first embodiment, the user first puts the material into the premixing tank 110, and then uses an external drive motor and a transmission component 130 to rotate the stirring component 140 inside the premixing tank 110, thereby achieving the premixing operation of the material inside the premixing tank 110, so that the material is mixed in the premixing tank 110 beforehand. After the mixing is completed, the user can rotate the premixing tank 110 between the supports to change the orientation of the opening on the upper surface of the premixing tank 110, so that it is aligned with the orientation of the cover plate. At this time, the operation can be carried out according to the operation steps of the first embodiment. Since the material composition is relatively complex in construction engineering, such as concrete containing cement, sand, gravel, admixtures and other components, the stirring component 140 in the premixing tank 110 can perform preliminary mixing of these materials during the premixing stage. Through stirring, materials with different densities and particle sizes can be initially mixed evenly, avoiding excessive local component differences in the subsequent fine mixing process, and making them initially more evenly distributed.
[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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
