Description

Technical Field

[0001] This utility model belongs to the field of concrete mixing technology, and in particular relates to a vibrating feeding structure for aggregate bins in concrete mixing plants. Background Technology

[0002] The aggregate bin vibrating feeder is a vibrating feeding device specifically designed for the storage and conveying of aggregates (such as crushed stone, sand, ore and other granular materials). It is usually installed below or on the side of the aggregate bin. Through the power generated by mechanical vibration, it conveys the aggregate in the bin evenly and continuously to the subsequent processing equipment (such as crushers, screening machines, mixers, etc.), and plays a role in controlling the material flow and regulating the conveying speed.

[0003] During the feeding process of aggregate bins into vibrating feeders, aggregates are prone to forming arches (hollow material retention phenomenon caused by aggregate blockage) due to differences in moisture content and particle size. This makes it difficult for aggregates to be fed stably. At the same time, fine aggregates or wet materials are prone to adhering to the bin walls, forming an adhesive layer, which affects the feeding efficiency. Therefore, it is necessary to provide a vibrating feeding structure for aggregate bins in concrete mixing plants, using mechanical arch breaking and inner wall scraping to specifically treat coarse and fine aggregates or dry and wet aggregates in the bins, so as to avoid the occurrence of aggregate bin blockage.

[0019] In the following description, embodiments of the vibratory feeding structure for aggregate bins in concrete mixing plants according to the present invention will be described with reference to the accompanying drawings.

[0020] Figure 1-4 This invention illustrates a vibratory feeding structure for an aggregate bin in a concrete mixing plant, comprising a bin 1. A vibratory feeding trough 2 is located at the bottom of the bin 1. The outlet of the bin 1 extends into the inner cavity of the vibratory feeding trough 2. A rotating ring 3 is located at the bottom of the inner wall of the bin 1. A connecting arm 4 is fixedly connected to the right side of the inner cavity of the rotating ring 3. A stirring rod 5 is fixedly connected to the top of one side of the connecting arm 4. Two limiting tubes 13 are welded to the surface of the stirring rod 5. Two limiting rods 12 are welded to the surface of the shovel plate 6. The limiting rods 12 are slidably connected to the limiting tubes 13. The inner cavity of the stirring rod 5, through the cooperation of the limiting rod 12 and the limiting tube 13, plays a limiting and guiding role for the shovel plate 6, improving the stability of the shovel plate 6 during sliding and its reliability during rotation. The shovel plate 6 is slidably connected to the inner cavity of the stirring rod 5. The right side of the shovel plate 6 is in contact with the inner wall of the hopper 1. A reducer 7 is fixedly installed on the top left side of the hopper 1. A servo motor 8 is fixedly installed on the bottom of the reducer 7. The output shaft of the servo motor 8 is fixedly connected to the input shaft of the reducer 7. A gear is fixedly connected to the output shaft of the reducer 7. A gear ring 10 is fixedly connected to the surface of the rotating ring 3, and the gear ring 10 meshes with the gear 11. An adjustment assembly 9 is provided on the surface of the stirring rod 5. The adjustment assembly 9 includes a fixing sleeve 91 fixedly connected to the surface of the stirring rod 5. An adjustment bolt 92 is rotatably connected to the inner cavity of the fixing sleeve 91. A threaded hole 93 is opened on the surface of the shovel plate 6. The bottom end of the adjustment bolt 92 passes through the inner cavity of the stirring rod 5 and is threadedly connected to the threaded hole 93. Threaded pins 94 are welded to the top and bottom of the shovel plate 6. Threaded pins 94 are opened at the top and bottom of the stirring rod 5. The arc-shaped groove 95 has a threaded pin 94 that passes through its inner cavity and is threadedly connected to a nut 96. By adjusting the assembly 9, the adjusting bolt 92 and the threaded hole 93 work together to push the scraper plate 6 forward, allowing it to slide within the inner cavity of the stirring rod 5. At the same time, the threaded pin 94, the arc-shaped groove 95, and the nut 96 work together to lock and fix the scraper plate 6, ensuring that it can be stably positioned in the designated position within the inner cavity of the stirring rod 5 after adjustment.

[0021] Working principle: When using this utility model, the user rotates the adjusting bolt 92, causing it to rotate within the cavity of the fixing sleeve 91. Simultaneously, the adjusting bolt 92, through the engagement of its surface thread and the inner wall thread of the threaded hole 93, pushes the scraper plate 6, causing the side of the scraper plate 6 away from the stirring rod 5 to contact the inner wall of the hopper 1. Then, the user rotates the nut 96, compressing the surface of the stirring rod 5, thereby locking and fixing the scraper plate 6. During use, the aggregate falls from the inner cavity of the hopper 1 into the inner cavity of the vibrating feed trough 2, and is conveyed forward by the vibrating feed trough 2. At the same time, the servo motor 8 is turned on and drives the reducer 7 to run. The reducer 7 drives the gear 11 to rotate, causing the rotating ring 3 to rotate within the inner cavity of the hopper 1. This causes the connecting arm 4, stirring rod 5, and scraper plate 6 to rotate simultaneously. During the rotation, the stirring rod 5 breaks up the blocked aggregate, and the scraper plate 6 scrapes off the aggregate adhering to the inner wall of the hopper 1.

[0022] In summary, the vibratory feeding structure of the aggregate bin in this concrete mixing plant, through the coordinated use of reducer 7, servo motor 8, gear ring 10 and gear 11, drives the connecting arm 4 to rotate in the inner cavity of the bin 1. At the same time, the mixing rod 5 breaks up the arches of the aggregate in the inner cavity of the bin 1, and the scraper plate 6 removes the aggregate adhering to the inner wall of the bin 1. This achieves the purpose of discharging materials with different moisture content and effectively preventing the inner wall from adhering and clogging.
