Description
Technical Field
[0001] This utility model belongs to the field of automatic mixing technology, and in particular relates to a high-efficiency automatic concrete mixing device. Background Technology
[0002] In construction, a large amount of concrete is needed to ensure good connections between buildings. Concrete mixing mainly includes traditional manual mixing and automated mixing.
[0003] However, the automated mixing equipment widely used in the market at present mainly uses unidirectional mixing. When mixing concrete, unidirectional mixing often makes it difficult to fully mix the various components in the concrete due to the single mixing direction. Repeated mixing is required, which greatly increases the time required for mixing, leading to increased workload and reduced mixing efficiency. To address this, we propose a high-efficiency automatic concrete mixing device. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency automatic concrete mixing device. Specifically, a mixing frame drives several mixing blades to rotate, and a scraper adheres to the inner wall of the mixing drum, scraping concrete off the drum wall during mixing to prevent hardening and cleaning difficulties after use. A round rod drives several mixing blades to rotate, and the mixing blades work in opposite directions with the mixing blades to achieve a more thorough mixing effect. This bidirectional mixing allows for uniform mixing of concrete in a short time, improving mixing efficiency. This invention solves the problem that widely used automated mixing equipment on the market primarily uses unidirectional mixing. Unidirectional mixing often fails to fully mix the various components of concrete due to the single mixing direction, requiring repeated mixing, significantly increasing the time required, workload, and reducing mixing efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a high-efficiency automatic concrete mixing device, including a base and a vertical plate, wherein the top of the base is fixedly connected to the bottom of the vertical plate;
[0007] A mixing assembly is installed on the vertical plate above the base. The mixing assembly includes a mixing tank, with fixed frames fixedly connected to the left and right sides of the mixing tank. A protective shell is installed below the center of the fixed frames. Three bevel gears are installed inside the protective shell, and the three bevel gears are meshed with each other. The bevel gear on the right side is rotatably connected to the inner wall of the right side of the protective shell. A motor is fixedly connected to the top of the protective shell. The top of the top bevel gear is fixedly connected to the bottom output end of the motor. A round rod is fixedly connected to the bottom of the top bevel gear. Several mixing blades are fixedly connected to the outer surface of the round rod. A mixing frame is fixedly connected to the bottom of the bottom bevel gear. Several scrapers are fixedly connected to the outer surface of the mixing frame. Several mixing blades are fixedly connected to the inner surface of the mixing frame. The round rod drives the several mixing blades to rotate. The mixing blades cooperate with the mixing blades in opposite directions to make the mixing effect more thorough. Under bidirectional mixing, the concrete can be mixed evenly in a short time and the mixing efficiency can be improved.
[0008] Furthermore, a support plate is fixedly connected to the bottom of the protective shell. The left and right surfaces of the support plate are fixedly connected to the inner wall of the mixing tank. The support plate fixes the bottom of the protective shell, making the mixing more stable during operation. The protective shell provides protection for the first bevel gear to prevent excessive material from being added, and prevents particles in the concrete from affecting the normal operation of the three first bevel gears.
[0009] A tilting component is provided on the left side of the stirring assembly. The tilting component includes a tilting frame, and a limiting shaft is fixedly connected to the inner top of the tilting frame. The limiting shaft limits the stirring tank, making it more stable during the adjustment of the stirring tank and preventing tilting.
[0010] Furthermore, the surface of the limiting shaft is rotatably connected to the inner side of the top center of the fixed frame, and a limiting hole is opened at the bottom of the flipping frame. The limiting hole also plays a limiting role for the mixing tank. The limiting hole and the limiting shaft cooperate with each other to provide stable support for the mixing tank.
[0011] Furthermore, the limiting hole is rotatably connected to the bottom of the mixing tank, and a second motor is fixedly connected to the inner side of the bottom of the tilting frame. A third bevel gear is fixedly connected to the top output end of the second motor. The second motor provides power for adjusting the angle of the mixing tank and can output power continuously and stably. The rotation direction of the mixing tank can also be controlled by changing the rotation direction of the second motor.
[0012] Furthermore, a bevel gear two is provided on the left side of the bevel gear three. The bottom of the bevel gear two meshes with the left side of the bevel gear three. The bevel gear three and the bevel gear two cooperate with each other. The bevel gear three rotates along the tooth groove of the bevel gear two, making the adjustment angle more precise and more stable when adjusting the angle.
[0013] Furthermore, the left side of the second bevel gear is fixedly connected to the right side of the vertical plate, and the center of the second bevel gear is rotatably connected to a rotating shaft. The right surface of the rotating shaft is rotatably connected to the inner side of the tilting frame, and the left side of the rotating shaft is rotatably connected to the inner side of the vertical plate. The rotating shaft provides a support center point for adjusting the angle, thus defining the rotation range and making it more standardized.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model sets up a mixing component, specifically a mixing frame that drives several mixing blades to rotate, and a scraper that adheres to the inner wall of the mixing bucket to scrape off the concrete on the bucket wall during the mixing process. This prevents the concrete from hardening and becoming difficult to clean after use if it is not cleaned in time. A round rod drives several mixing blades to rotate, and the mixing blades cooperate with the mixing blades to mix in opposite directions, making the mixing effect more thorough. Under bidirectional mixing, the concrete can be mixed evenly in a short time and the mixing efficiency can be improved.
[0016] 2. This utility model, by setting up a flipping component, specifically, the rotation of bevel gear three drives the flipping frame to rotate around the pivot shaft along the tooth groove of bevel gear two. The flipping frame drives the mixing bucket to rotate to a suitable position, pouring out the mixed concrete. After pouring out the concrete, the mixing bucket is adjusted to a suitable angle for cleaning, making the cleaning work after use more convenient, reducing the difficulty of cleaning, and improving the cleaning efficiency.

During the mixing process, the concrete on the bucket wall is scraped off, preventing the concrete from hardening and making cleaning difficult if it is not cleaned in time after use. The round rod 114 drives several mixing blades 141 to rotate. The mixing blades 141 and the mixing blades 182 cooperate with each other to stir in opposite directions, so that the mixing effect is more thorough. Under bidirectional stirring, the concrete can be mixed evenly in a short time and the mixing efficiency can be improved.
[0030] A support plate 117 is fixedly connected to the bottom of the protective shell 112, and the left and right surfaces of the support plate 117 are fixedly connected to the inner wall of the mixing tank 111.
[0031] A tilting assembly 12 is provided on the left side of the mixing assembly 11. The tilting assembly 12 includes a tilting frame 121. A limiting shaft 211 is fixedly connected to the inner top of the tilting frame 121. By setting the tilting assembly 12, specifically, the bevel gear 3 241 rotates and drives the tilting frame 121 to rotate around the rotating shaft 122 along the tooth groove of the bevel gear 2 123. The tilting frame 121 drives the mixing bucket 111 to rotate to a suitable position, and the mixed concrete is poured out.

[0036] A specific application of this embodiment is as follows: Various pre-prepared raw materials are poured into the mixing drum 111 according to a predetermined ratio. Then, the motor 115 is started, driving the upper bevel gear 116 to rotate. The rotation of bevel gear 116 drives the right bevel gear 116, causing it to rotate synchronously. As the right bevel gear 116 rotates, the lower bevel gear 116 is also driven, causing the mixing frame 118 to rotate. The mixing frame 118 drives several scrapers 181 and mixing blades 182 to rotate. The scrapers 181 are tightly attached to the inner wall of the mixing drum 111, continuously scraping down concrete from the drum wall during mixing, reducing concrete residue inside the drum and facilitating maintenance. The mixing blades 182 are driven by the mixing frame 118. The raw materials are thoroughly mixed together. At the same time, the upper bevel gear 116 drives the rotation of the round rod 114, and several stirring blades 141 on the round rod 114 also begin to rotate. The stirring blades 141 and stirring blade 182 work together to form a reverse stirring effect, making the stirring effect more thorough and uniform. After the stirring work is completed, the motor 124 drives the rotation of the bevel gear 241, and the bevel gear 241 drives the tilting frame 121 to rotate around the rotating shaft 122 along the tooth groove of the bevel gear 123. The tilting frame 121 rotates together with the mixing bucket 111 to a suitable position, and the mixed concrete is poured out smoothly. After the concrete is poured out, the angle of the mixing bucket 111 can be adjusted again to place it in a position that is easy to clean, reducing the difficulty of cleaning and improving efficiency.
