[0002] In industrial production, feeding silos, as key equipment for material storage and dispensing, are widely used in various industries such as chemicals, food processing, and building materials. Traditional feeding silos have relatively simple functions, only capable of basic material storage and dispensing. When handling materials that are prone to caking or have uneven composition, these feeding silos struggle to ensure material uniformity, leading to unstable product quality in subsequent production stages. Furthermore, traditional feeding silos often employ static screening methods, resulting in low screening efficiency and easy material clogging of the screens. This not only reduces production efficiency but also increases the workload and cost of manually cleaning the screens.

[0003] Therefore, it is necessary to provide a new feeding hopper with a stirring function to solve the above-mentioned technical problems. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] This utility model provides a feeding bin with a stirring function, which includes: a support frame 1; a feeding bin 11 installed on the top of the support frame 1, and a cover plate 12 connected to the top of the feeding bin 11; wherein, a stirring component is provided inside the feeding bin 11, and the stirring component can stir the material inside the feeding bin 11; a screen plate 2 is slidably connected inside the feeding bin 11, and a screening component for driving the screen plate 2 to move up and down is installed on the top of the cover plate 12.

[0021] It should be noted that: the mixing component is installed inside the feeding hopper 11, which breaks the static accumulation of materials within the hopper, effectively preventing material agglomeration and stratification. The sieve plate 2 is slidably connected within the feeding hopper 11, enabling the screening of the input materials based on particle size. The screening component is installed on top of the cover plate 12, driving the sieve plate 2 to move up and down, forming a dynamic screening mode. A discharge valve is installed at the bottom of the feeding hopper 11; the discharge valve is an existing, mature structure and will not be further described here. A feeding port is provided at the top of the cover plate 12.

[0022] In an embodiment of this utility model, the stirring assembly includes a stirring shaft 3 rotatably connected to the bottom of the cover plate 12, and the stirring shaft 3 is located inside the feeding bin 11. Multiple stirring rods 31 are equidistantly connected to the bottom outer side of the stirring shaft 3. The top of each stirring rod 31 is inclined towards the inner side wall of the feeding bin 11. A bracket 32 ​​is installed at the bottom of the cover plate 12. A drive bevel gear 33 is rotatably connected to the bottom of the bracket 32. A transmission shaft 34 is connected to the bottom of the drive bevel gear 33. The bottom of the transmission shaft 34 passes through the top of the cover plate 12 and is connected to the top of the stirring shaft 3. A drive component for driving the drive bevel gear 33 to rotate is installed at the top of the bracket 32.

[0023] It should be noted that the stirring shaft 3 is rotatably connected to the bottom of the cover plate 12 and extends into the feeding bin 11. As the core component of the stirring assembly, it provides stable power transmission for the stirring operation. Multiple stirring rods 31 are equidistantly connected to the bottom outer side of the stirring shaft 3. The design of the top of the stirring rods 31 inclined towards the inner wall of the feeding bin 11 allows the material to form a three-dimensional circulating flow along the bin wall and axis during the stirring process. When the material is mixed, the stirring rods 31 not only push the material in the central area outwards but also bring the material near the bin wall back to the center, effectively preventing material accumulation near the bin wall and greatly improving the uniformity of mixing. The transmission system composed of the active bevel gear 33 and the drive shaft 34 ensures stable power transmission from the drive component to the stirring shaft 3. The bracket 32 ​​not only provides stable support for the active bevel gear 33 but also optimizes the layout of the entire transmission structure. The drive component is an electric motor mounted on top of the bracket 32, providing power for the rotation of the active bevel gear 33.

[0024] In an embodiment of this utility model, the screening assembly includes a transmission rod 21 installed on the top of the cover plate 12, and the two transmission rods 21 are arranged opposite to each other. The relatively close ends of the two transmission rods 21 are each connected to a driven bevel gear 22, and the relatively close sides of the two driven bevel gears 22 are each meshed with a driving bevel gear 33. The relatively far ends of the two transmission rods 21 are each connected to a cam 23. A lifting rod 24 is provided below each of the two cams 23. A limiting hole is provided on the cover plate 12 for the lifting rod 24 to pass through. The bottom of the two lifting rods 24 passes through the limiting hole and is respectively connected to the top two sides of the screen plate 2. An abutment pad 25 is connected to the top of the lifting rod 24, and the abutment pad 25 is located below the cam 23. A return spring 26 is sleeved on the outer top of the lifting rod 24, and the return spring 26 is located between the abutment pad 25 and the cover plate 12. A limiting block 27 is connected to the outer top of the lifting rod 24, and the limiting block 27 is located below the cover plate 12.

[0025] It should be noted that the screening assembly is installed on top of the cover plate 12, cleverly utilizing the power of the stirring assembly to achieve the up-and-down movement of the screen plate 2. The transmission rods 21 are mounted opposite each other on top of the cover plate 12, one end of which is connected to the driven bevel gears 22. The two driven bevel gears 22 mesh with the driving bevel gear 33. When the driving bevel gear 33 rotates under the drive of the driving component, it drives the driven bevel gears 22 and the transmission rods 21 to rotate synchronously through the meshing action. The cam 23 connected to the other end of the transmission rod 21 rotates accordingly. During the rotation of the cam 23, it periodically presses the abutment pad 25, pushing the lifting rod 24 downwards. The lifting rod 24 passes through the limiting hole on the cover plate 12 and connects to both sides of the top of the screen plate 2, thereby driving the screen plate 2 downwards. The design of the return spring 26 and the limiting block 27 ensures the smooth lifting and lowering of the screen plate 2. When the cam 23 rotates past the pressing position, the return spring 26 pushes the abutment pad 25 and the lifting rod 24 upwards to reset, and the screen plate 2 also rises accordingly.

[0026] The working principle of the feeding hopper with stirring function provided by this utility model is as follows: When the drive unit is started, the drive unit drives the active bevel gear 33 on the top of the support 32 to rotate. The active bevel gear 33 drives the stirring shaft 3 to rotate through the transmission shaft 34, and the stirring rod 31 installed at the bottom of the stirring shaft 3 rotates accordingly, stirring the material in the feeding hopper 11. Since the top of the stirring rod 31 is inclined towards the inner wall of the feeding hopper 11, the material forms a three-dimensional circulating flow during the stirring process, so that the material is fully mixed and prevents agglomeration and stratification. At the same time, the rotation of the active bevel gear 33 drives the two driven bevel gears 22 to rotate synchronously through meshing. The driven bevel gears 22 are installed at one end of the transmission rod 21, so their rotation will drive the transmission rod 21 to rotate, and the cam 23 installed at the other end of the transmission rod 21 will also rotate accordingly. During the rotation, the cam 23 periodically squeezes the abutment pad 25, pushing the lifting rod 24 to move downward. The lifting rod 24 passes through the limiting hole opened on the cover plate 12, and its bottom is connected to the top two sides of the screen plate 2, thereby driving the screen plate 2 to move downward. When cam 23 rotates past the pressing position, return spring 26 pushes the abutment pad 25 and lifting rod 24 upward to reset, and screen plate 2 also rises accordingly. This process is repeated, and screen plate 2 achieves dynamic screening by moving up and down to screen the material in feeding bin 11. Material that meets the specifications passes through screen plate 2, while material that does not meet the specifications is blocked.

[0027] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
