Description

Technical Field

[0001] This utility model relates to the technical field of concrete mixing equipment, and in particular to a fiber concrete mixing equipment. Background Technology

[0002] In the preparation process of hybrid fiber concrete, the raw materials and fibers for preparing hybrid fiber concrete are first selected, and the raw materials and fibers are weighed according to the proportion. Then, the raw materials are put into a mixer for mixing. Different fiber raw materials are added during the mixing process. After the mixture is evenly mixed by the mixer, the hybrid fiber concrete is discharged.

[0003] Application CN218985249U relates to a mixing device for hybrid fiber concrete, specifically within the technical field of fiber concrete mixing equipment. The device includes a frame and a mixing drum. The mixing drum is equipped with a mixing mechanism, which comprises a main mixing shaft, a dispersion disc, a secondary mixing shaft, and a drive assembly. The main mixing shaft has main mixing blades, and the secondary mixing shaft has secondary mixing blades. The main and secondary mixing shafts rotate in opposite directions. The drive assembly, when activated, causes the main and secondary mixing shafts to rotate in opposite directions. This causes the dispersion disc to rotate and disperse the fiber material. The main mixing blades then agitate the dispersed fibers, dispersing the fiber material into the concrete. Simultaneously, the rotation of the secondary mixing shaft drives the secondary mixing blades to rotate, further dispersing the fiber material through the dispersion disc. The combined action of the main and secondary mixing blades agitates the dispersed fiber material, ensuring its uniform dispersion in the concrete and thus improving the mixing effect of the hybrid fiber concrete.

[0004] The mechanical structures such as the sliding sleeve, limit rod, and rotating disk in the device disclosed in the above application require frequent manual operation, resulting in high labor costs. Long-term use can easily lead to positioning failure due to wear, increasing maintenance costs. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5A fiber-reinforced concrete mixing device includes a mixing drum 1, a top cover 2 on the mixing drum 1, a drive motor 3 on the top cover 2, a main drive gear 4 connected to the output shaft of the drive motor 3, a main mixing rod 5 connected to the shaft of the main drive gear 4, the main mixing rod 5 being located inside the mixing drum 1, a connecting base 6 being located outside the mixing drum 1 at the lower part of the drum body, a connecting block 7 being located at the outer edge of the top cover 2, the connecting block 7 being positioned corresponding to the connecting base 6, and an electric telescopic rod 8 being provided between the connecting block 7 and the connecting base 6, the body of the electric telescopic rod 8 being provided on the connecting base 6, and its telescopic rod being connected to the connecting block 7.

[0024] When using this equipment, the electric telescopic rod 8 is activated, and the moving rod of the electric telescopic rod 8 moves upward, thereby pushing the upper cover 2 upward. This removes the upper cover 2 from the mixing drum 1, making it easier to put concrete and fibers into the mixing drum 1 through the opening. After the materials are put in, the electric telescopic rod 8 drives the moving rod to move downward, so that the upper cover 2 closes on the mixing drum 1. Then, the transmission motor 3 drives the main transmission gear 4 to rotate, which in turn drives the main mixing rod 5 to rotate, thereby achieving the purpose of mixing the concrete.

[0025] Specifically, in this embodiment, the upper cover 2 has a cavity 9, the main drive gear 4 is located inside the cavity 9, the drive motor 3 is located on the upper part of the upper cover 2, and the output shaft of the drive motor 3 passes through the upper wall of the cavity 9 and is connected to the main drive gear 4. The cavity 9 allows the main drive gear 4 to be placed inside the upper cover 2, so that the upper cover 2 acts as a protective shell to protect the main drive gear 4 and prevent the main drive gear 4 from being contaminated with concrete and other dust, which would affect the normal mixing operation of the equipment.

[0026] Specifically, in this embodiment, three auxiliary transmission gears 10 mesh with the main transmission gear 4. All three auxiliary transmission gears 10 are located within the cavity 9, and each of the three auxiliary transmission gears 10 is connected to an auxiliary stirring rod 11 at its center. This allows the main transmission gear 4 to drive the three auxiliary transmission gears 10 to rotate synchronously in opposite directions when it rotates, thereby driving the three auxiliary stirring rods 11 to rotate. This results in the main stirring rod 5 rotating in the opposite direction to the three auxiliary stirring rods 11, thus breaking up the fibers and improving the stirring quality. At the same time, the arrangement of the three auxiliary stirring rods 11 can form a planetary motion trajectory, eliminating stirring dead zones.

[0027] Specifically, in this embodiment, the main drive gear 4 and the main stirring rod 5, and the auxiliary drive gear 10 and the auxiliary stirring rod 11 are all detachably connected. This allows the main stirring rod 5 or the auxiliary stirring rod 11 to be removed from the equipment without disassembling the screw. The disassembly and installation can be completed quickly by simply inserting and pulling, thus enabling rapid replacement.

[0028] Specifically, in this embodiment, the drive motor 3 is a variable frequency motor that supports stepless speed regulation from 0 to 1500 rpm. This allows for different adjustments to the speed of the stirring mechanism based on the softness or hardness of the fiber material, enabling it to meet the stirring requirements of different fiber materials and further improving the practicality of the device.

[0029] Specifically, in this embodiment, two water supply pipes 12 are provided on the bottom wall of the upper cover 2. One end of the two water supply pipes 12 is rotatably connected by a pipe, and a water injection pipe 18 is connected to the pipe. The water injection pipe 18 is used to connect to an external water source. Several rotary nozzles 13 are provided on the U-shaped water supply pipe 12. A first bevel gear 14 is provided at both ends of the U-shaped water supply pipe 12. A second bevel gear 15 is meshed on both first bevel gears 14. The two second bevel gears 15 are connected to the same drive shaft 16. One end of the drive shaft 16 is connected to the output shaft of the servo motor 17. After the stirring work is completed, the user can control several nozzles 13 to spray water into the stirring tank 1 by connecting a water source, thereby achieving the purpose of cleaning the stirring tank 1. By operating the servo motor 17, the rotation of the two second bevel gears 15 can be controlled, thereby driving the rotation of the two first bevel gears 14, which in turn drives the two water supply pipes 12 to rotate in opposite directions, thereby achieving the purpose of adjusting the angle of the nozzles 13, making the spraying area of ​​the nozzles 13 wider, thereby improving the cleaning efficiency.

[0030] Specifically, in this embodiment, a protective shell 19 is provided on the bottom wall of the upper cover 2. The water supply pipe 12, the first bevel gear 14, the second bevel gear 15 and the servo motor 17 are all inside the protective shell 19. Several nozzles 13 extend through the protective shell 19 into the mixing tank 1. The protective shell 19 can effectively protect each cleaning component, prevent it from being contaminated with concrete and affecting the normal operation of each component, and at the same time facilitate the nozzles 13 to perform normal cleaning work.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
