The fiber material and concrete are mixed through the concrete preparation equipment, and the tensile, bending, impact strength, elongation and toughness of the concrete produced are improved.

[0003] The existing technology has the following problems: after the existing concrete preparation device has been in operation for a long time, a large amount of residual concrete will accumulate inside the device, which is troublesome to clean up and will condense inside the device after a long time, affecting the operation of internal components. Utility Model Content

[0007] By adopting the above technical scheme, a first feed port and a second feed port are respectively provided on the shell, and fiber materials and concrete raw materials can be respectively placed in the shell, and the first rotating rod and the stirring rod, the second rotating rod and the stirring rod stir the fiber materials and the concrete materials respectively, and the stirred fiber materials and concrete raw materials are filtered through a screen, and then mixed and stirred by a stirring rod. When the stirring rod stirs the mixed material, the support rod simultaneously supports the first scraper to scrape the inner wall of the shell, which can reduce the adhesion and accumulation of the mixed material on the shell, so as to reduce the waste of materials and improve the mixing preparation efficiency of the device.

[0008] Optionally, the driving assembly includes a first motor, a driving gear, a driven gear and a connecting gear.

[0018] Optionally, a propeller is fixed on the central shaft along the circumference, and the propeller is fixed below the stirring rod.

[0019] By adopting the above technical solution, a propeller is fixed under the stirring rod, which can not only fully stir the mixed material, but also transmit the mixture stirred by the stirring rod to the discharge port, thereby increasing the stirring and transmission efficiency of the mixture of fiber material and concrete material in the shell.

[0020] Optionally, the diameter of one end of the shell close to the discharge port gradually shrinks toward the middle.

[0021] By adopting the above technical solution, the diameter of one end of the shell near the discharge port gradually shrinks, so that the stirred mixture in the shell can fall to the discharge port to reduce adhesion and accumulation on the inner wall of the shell.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The first rotating rod and the first stirring rod, the second rotating rod and the second stirring rod can stir the fiber material and the concrete material respectively, and the stone crusher can also crush the particles with larger diameters, so that the diameter of the mixed materials is more uniform and the mixing is more complete;
