Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mixers, in particular to a mixer used in a concrete mixing station. Background Art
[0002] As an important piece of machinery, a concrete mixer's primary function is to mix cement, sand and gravel aggregate, and water to create a concrete mixture. However, in actual operation, site constraints can lead to incomplete or improper mixing of the various materials, preventing the full performance of each component. This uneven mixing can affect the strength of buildings using the concrete and potentially lead to a series of quality issues. Therefore, to ensure concrete quality and building safety, the use of a mixer is essential for mixing and stirring concrete materials.
[0003] Most current concrete mixers rely on a single mixing shaft for stirring and mixing. However, concrete easily sticks to and accumulates on the inner wall of the mixer when it comes into contact with water, resulting in uneven mixing. It takes a long time to continuously stir the concrete, which reduces the mixing efficiency and affects work efficiency. Utility Model Content

[0006] Preferably, the upper end of the transmission shaft is fixedly connected to a mounting bracket, the mounting bracket is connected to the stirring box via screws, and the upper end of the stirring shaft is clamped to a stirring rod.
[0007] Preferably, both sides of the base are axially connected to brackets, one side of the bracket is axially connected to a pull rod, and the pull rod abuts against one side of the bracket through a limit screw.
[0008] Preferably, limiting rods are diagonally engaged on both sides of the bracket, and the limiting rods abut against the base.

[0010] Preferably, the stirring shaft is connected to the transmission shaft via a bearing.
[0011] Compared with the prior art, the beneficial effects achieved by the present invention are:
[0012] First, the present invention utilizes a drive motor, a mixing shaft, and a mixing tank to ensure thorough mixing of concrete. The drive motor drives the gears, which mesh and rotate the first and second gears in opposite directions. The first gear drives the mixing shaft, while the second gear drives the transmission shaft. The transmission shaft drives the mounting bracket, which in turn drives the mixing tank. The mixing tank rotates in opposite directions to the mixing shaft, ensuring thorough mixing of concrete and water, preventing adhesion and improving mixing efficiency and work efficiency.
[0013] Second, the present invention can quickly pour out concrete by arranging pull rods and brackets. The limit rods on both sides of the brackets are removed. At this time, the limit screws are unscrewed by manpower, and the pull rods are pushed to drive the limit box to tilt, and the concrete in the mixing box is poured out, which makes it easier for workers to pour concrete from the mixing box, thereby increasing the speed of loading and unloading concrete and further improving work efficiency.

[0020] See also Figure 1-4A mixer for a concrete mixing station includes a base 2 and a limit box 3. The upper end of the base 2 is fixedly connected to the limit box 3. The base 2 is fixedly connected to the support frame 8. One side of the support frame 8 is fixedly connected to the drive motor 9. A drive gear 10 is provided in the middle of the drive motor 9. The two sides of the drive gear 10 are respectively engaged with the first gear 11 and the second gear 12. The first gear 11 is fixedly connected to the stirring shaft 14. The second gear 12 is fixedly connected to the transmission shaft 13. A stirring box 16 is installed on the transmission shaft 13. The stirring shaft 14 is inserted into the middle of the stirring box 16. The drive motor 9 drives the drive gear 10 to rotate. The drive gear When 10 rotates, the meshing drives the first gear 11 and the second gear 12 to rotate in opposite directions. The first gear 11 drives the stirring shaft 14 to rotate, and the second gear 12 drives the transmission shaft 13 to rotate. The transmission shaft drives the mounting frame 15 to rotate, and the mounting frame 15 drives the mixing box 16 to rotate. The first gear 11 and the second gear 12 drive the mixing box 16 to rotate in the opposite direction to the stirring shaft 14. The mixing box 16 rotates in the opposite direction to the stirring shaft 14, so that the concrete and water inside the mixing box 16 are fully mixed, and the concrete is prevented from accumulating and adhering to the inner wall of the mixing box 16, thereby improving the mixing efficiency and further improving the work efficiency.
[0021] The upper end of the transmission shaft 13 is fixedly connected to the mounting bracket 15, and the mounting bracket 15 is connected to the mixing box 16 by screws. The upper end of the mixing shaft 14 is clamped with the mixing rod.
