[0016] 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.

[0017] Example: Please see Figures 1 to 5 This utility model provides a technical solution: A vibratory fiber dispersion feeder for fresh concrete includes a storage silo 1, a feeding assembly 2, a vibrating screen assembly 3, a primary dispersion assembly 4, and a rubber pad 5. The storage silo 1 has an internal mounting frame 11, wherein: The vibrating screen assembly 3 is mounted on the mounting frame 11, and the primary dispersion assembly 4 is mounted on the vibrating screen assembly 3; The primary dispersion component 4 includes a rotating disk 41, a conical guide frame 42, star-shaped material distribution discs 43, and a power component 44. The rotating disk 41 is rotatably mounted on the vibrating screen component 3 and faces the feeding end of the feeding component 2. Fibers falling from the feeding component 2 will touch the conical guide frame 42, and under the action of the conical guide frame 42, the fibers can be dispersed for the first time. The conical guide frame 42 is located at the center of the rotating disk 41. At least three star-shaped material distribution discs 43 are rotatably mounted on the rotating disk 41 in a circumferential array and are arranged around the conical guide frame 42. After passing through the conical guide frame 42, the fibers are dispersed. The fibers initially dispersed by the conical guide frame 42 fall onto the rotating disk 41. As the disk 41 rotates, the fibers on it rotate with it, and under centrifugal force, the fibers move outwards from the disk 41. This allows heavier fibers to fall off the disk 41 earlier, thus dispersing them according to their weight. Meanwhile, some fibers will contact the star-shaped material distribution disk 43. As the star-shaped material distribution disk 43 rotates, its edges will agitate the contacting fibers, further dispersing them. The power unit 44 is mounted on the vibrating screen assembly 3 and is poweredly connected to the rotating disk 41, the conical guide frame 42, and the star-shaped material distribution disk 43.

[0018] In a preferred embodiment, the vibrating screen assembly 3 includes a rotary vibrating frame 31, a spring 32, and a vibrating motor 33. The rotary vibrating frame 31 is movably mounted on the mounting frame 11 via the spring 32. The rotary vibrating frame 31 is a conical shape, narrower at the top and wider at the bottom. The vibrating motor 33 is mounted on the mounting frame 11 and is poweredly connected to the rotary vibrating frame 31. Fibers passing through the primary dispersion assembly 4 fall onto the side of the rotary vibrating frame 31, and the vibrating motor 33 can drive the rotary vibrating frame 31 to vibrate, thus further dispersing the fibers.

[0019] As a preferred embodiment, driving the rotary vibrating frame 31 to vibrate via the vibrating motor 33 is a conventional technical means in the field of vibrating screens, and its principle and solution will not be elaborated here.

[0020] In a preferred embodiment, the power assembly 44 includes an inner gear ring 441, gear I 442, gear II 443, and a motor 444. The inner gear ring 441 is fixedly mounted on the rotary vibrating frame 31. Gear I 442 is rotatably mounted on the rotary vibrating frame 31. Gear II 443, which is the same number as the star-shaped material distribution plate 43, is rotatably mounted on the rotating disk 41. The inner gear ring 441 and gear I 442 are coaxial and concentric, with gear I 442 located inside the inner gear ring 441. Gear II 443 is located between the inner gear ring 441 and gear I 442 and meshes with both of them. The rotating disk 41 is connected to gear I 442, and the two are concentrically arranged. The star-shaped material distribution plate 43 and gear II 443 are connected by a coupling. The motor 444 is mounted on the rotary vibrating frame 31 and is powered by gear I 442.

[0021] In a preferred embodiment, the rotating disk 41 is rotatably mounted on the upper end of the rotary vibration frame 31. The rotating disk 41 functions similarly to the planet carrier in a planetary gear assembly.

[0022] In a preferred embodiment, the conical guide frame 42 has a series of loose material blocks 421 arranged on its curved surface. For example... Figure 4 As shown, the bulk material block 421 is used to further break up the fibers.

[0023] In a preferred embodiment, the feeding assembly 2 includes a rotary feeding bin 21, a sealing plate 22, and an electric push rod 23. The rotary feeding bin 21 is provided at the upper end of the storage bin 1. The rotary feeding bin 21 is a conical shape that is wider at the top and narrower at the bottom. Two sealing plates 22 are movably installed at the feeding port of the rotary feeding bin 21. The electric push rod 23 is provided on the rotary feeding bin 21 and is poweredly connected to the sealing plate 22.

[0024] In a preferred embodiment, a rubber pad 5 is provided between the mounting frame 11 and the rotary vibrating frame 31. The rubber pad 5 is used to prevent fibers from entering the interior of the mounting frame 11.

[0025] In a preferred embodiment, there is a gap between the mounting frame 11 and the storage bin 1 to allow fibers to pass through.

[0026] The working principle of this utility model: In use, the fiber enters the sealing plate 22 from the rotary feeding hopper 21. Then, two electric push rods 23 drive the two sealing plates 22 away from each other, causing the fiber to fall from the outlet of the rotary feeding hopper 21 onto the conical guide frame 42. Under the action of the conical guide frame 42, the fiber can be dispersed for the first time. The fiber dispersed by the conical guide frame 42 will fall onto the rotating disk 41. Since the rotating disk 41 rotates, it will cause the fiber on it to rotate with it. Then, under the action of centrifugal force, the fiber will move to the outside of the rotating disk 41. This allows the heavier fiber to fall off the rotating disk 41 earlier. Thus, the fiber can be dispersed according to its weight. At this time, some fiber will also come into contact with the star-shaped dispersing disk 43. When the star-shaped dispersing disk 43 rotates, its edges will push the fiber in contact with it, thus further dispersing the fiber. After passing through the primary dispersion component 4, the fibers fall onto the side of the rotary vibrating frame 31, and the vibration motor 33 can drive the rotary vibrating frame 31 to vibrate, thus further dispersing the fibers.

[0027] The fibers passing through the rotating vibrating frame 31 will fall from the discharge hole between the rotating vibrating frame 31 and the storage bin 1, and then fall from the gap between the mounting frame 11 and the storage bin 1 into the mixing device or the conveying device.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
