Description

Technical Field

[0001] This utility model relates to the technical field of grain machinery, and in particular to a buffer feeding steel silo. Background Technology

[0002] A buffer feed silo is an industrial device used for material storage and buffering. It is mainly used to solve problems such as unstable feeding rate, material accumulation or material interruption in the production process, and to ensure the continuity and stability of subsequent processes.

[0003] In related technologies, traditional steel silos typically use simple vertical feed pipes or inclined chutes for direct feeding. The buffer design relies on fixed baffles or static buffer layers (such as rubber pads or ramp structures), resulting in a relatively simple structure. High-speed material falling directly impacts the bottom of the silo or accumulates materials, which can easily lead to silo deformation and material breakage. At the same time, the uneven distribution of materials by fixed distribution plates can easily cause material accumulation and eccentricity, affecting the smoothness of discharge and even causing blockages. Some improved solutions use hydraulically driven movable baffles or rotary distributors, which lack dynamic adjustment capabilities. They utilize static buffer structures, which cannot adapt to different feed rates, are prone to material accumulation, require frequent cleaning, have low buffering efficiency, and increase the labor intensity of workers. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a buffered feeding steel silo that integrates dynamic volume adjustment, multi-level buffering, and mechanical guidance functions to achieve full control over the material from feeding to accumulation in the silo. It can adjust the volume of the feeding chamber in real time to adapt to different feeding rates. At the same time, it can perform segmented buffering and material distribution to achieve multi-level buffering, actively gather and disperse the falling material, improve the uniformity of material distribution, reduce manual intervention, effectively reduce the labor intensity of workers, and improve the feeding buffering efficiency.

[0006] To achieve the above objectives, this utility model proposes a buffer feed steel silo, comprising a silo body and a feeding mechanism. The silo body is provided with an inlet and an outlet. The feeding mechanism includes a feed baffle, two symmetrically arranged first driving devices, a packing assembly, and a propulsion assembly. The feed baffle is movably connected to the silo body through the two symmetrically arranged first driving devices and forms a feeding cavity between the baffle and the inner wall of the silo body. The packing assembly is disposed on the inlet and communicates with the feeding cavity. The propulsion assembly is disposed on the packing assembly and located below the packing assembly.

[0007] In addition, the buffer feed steel silo proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the packing assembly includes a limiting baffle, a feed pipe, a cover plate, and a first distribution plate. The limiting baffle is disposed on the feed inlet, the feed pipe is movably connected to the limiting baffle, the limiting baffle has a first through hole, the cover plate is movably connected to the feed pipe, and the first distribution plate is disposed on the feed pipe.

[0009] Specifically, the feed baffle has a second through hole and multiple third through holes.

[0010] Specifically, the propulsion assembly includes a second driving device, a rotating rod, a spiral blade, two actuating plates, multiple positioning rods, and a second distributing plate. The second distributing plate is disposed on the feed baffle via the multiple positioning rods and is located below the feed baffle. The rotating rod is rotatably connected to the second distributing plate via the second driving device, passes through the second through hole, and is located below the feed pipe. The spiral blade is disposed on the rotating rod, and the two actuating plates are disposed on the rotating rod.

[0011] Specifically, the two actuating plates are respectively arranged in an arc shape and are in contact with the feed baffle.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The buffer feed steel silo of this utility model embodiment will be described below with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, the buffer feeding steel silo of this utility model embodiment may include a silo body 1 and a feeding mechanism 2.

[0024] The silo body 1 is equipped with an inlet 11 and an outlet 12.

[0025] It should be noted that the bin body 1 described in this embodiment can stably support the feeding mechanism 2, and the feeding port 11 is located on the upper part of the bin body 1, the feeding mechanism 2 is located inside the feeding port 11, and the discharge port 12 is located at the bottom of the bin body 1.

[0026] The feeding mechanism 2 includes a feeding baffle 21, two symmetrically arranged first drive devices 22, a filling assembly 23, and a propulsion assembly 24.

[0027] The feed baffle 21 is movably connected to the hopper 1 through two symmetrically arranged first drive devices 22, and forms a feed cavity 211 between it and the inner wall of the hopper 1. The packing assembly 23 is disposed on the feed inlet 11 and communicates with the feed cavity 211. The propulsion assembly 24 is disposed on the packing assembly 23 and is located below the packing assembly 23.

[0028] It should be noted that the first driving device 22 proposed in the above embodiment adopts a cylinder. It is stably connected to and adjusts the height of the feed baffle 21 through a set of symmetrical cylinders, and adjusts the volume of the feed chamber 211 in real time to adapt to different feed rates. When the volume of the feed chamber 211 is expanded, the feed rate of the feed pipe 232 can be increased, and the rotation speed of the second driving device 241 can be increased, thereby increasing the buffer feed rate inside the hopper 1, and segmented buffering and material distribution are realized in sequence through the packing assembly 23 and the propulsion assembly 24.

[0029] Specifically, during the actual feeding process, relevant personnel open the cover plate 233 on the feed pipe 232 and connect it with the filling device (not shown in the figure). In the initial state, the first drive device 22 is in a retracted state, the feed baffle 21 is located at the highest point inside the silo 1, the feed chamber 211 has the smallest volume, and at the same time, the first through hole 2311 on the side wall of the feed pipe 232 coincides with the limiting baffle 231, blocking the material from falling through the first through hole 2311.

[0030] During feeding, when the first drive device 22 extends, the feed pipe 232, feed baffle 21, and propulsion assembly 24 move downwards synchronously, and the volume of the feed chamber 211 expands. The material in the feed pipe 232 slides down the inclined surface of the first distribution plate 234 and falls into the receiving chamber through multiple first through holes 2311. Then, the second drive device 241 is driven, which drives the spiral blade 243 and two actuating plates 244 to rotate. The two actuating plates 244 adhere to the upper wall of the feed baffle 21 and gather the material towards the center. When the material is actuated, it passes through... The material is dispersed and falls into the bottom of the silo 1 through multiple second through holes 212. At the same time, some material is gathered to the center of the feed baffle 21 and falls downward through the third through hole 213. The spiral blades 243 on the central rotating rod 242 push the material downward at a uniform speed, falling onto the second distribution plate 246 and scattering it around. This achieves uniform and buffered material drop, making the entire process from material feeding to accumulation in the silo controllable, improving the uniformity of material distribution, reducing manual intervention, effectively reducing the labor intensity of workers, and improving the feeding buffer efficiency.

[0031] After feeding, the first drive device 22 is driven to retract, closing the first through hole 2311 and fastening the cover plate 233, increasing the sealing of the silo 1. At the same time, the volume of the storage cavity is reduced, increasing the material storage volume.

[0032] In one embodiment of this utility model, such as Figure 2 , Figure 3and Figure 5 As shown, the packing assembly 23 includes a limiting baffle 231, a feed pipe 232, a cover plate 233, and a first distribution plate 234.

[0033] The limiting baffle 231 is provided on the feed inlet 11, the feed pipe 232 is movably connected to the limiting baffle 231, the limiting baffle 231 has a first through hole 2311, the cover plate 233 is movably connected to the feed pipe 232, and the first material distribution plate 234 is provided on the feed pipe 232.

[0034] It should be noted that the bottom of the feed pipe 232 described in this embodiment is closed and forms a cavity with the first distribution plate 234. The first through holes 2311 are evenly distributed on the side wall of the feed pipe 232. The first distribution plate 234 is frustum-shaped and the bottom of the inclined surface is located below the first through hole 2311. When feeding, the material slides down the inclined surface of the first distribution plate 234 and exits through the first through hole 2311 into the receiving cavity, realizing a first-level buffer and reducing the initial kinetic energy.

[0035] In one embodiment of this utility model, such as Figure 3 , Figure 4 and Figure 5 As shown, the feed baffle 21 has a second through hole 212 and multiple third through holes 213.

[0036] It should be noted that the second through hole 212 described in this embodiment is located at the center of the feed baffle 21, and a plurality of third through holes 213 are arranged in a circular pattern with equal spacing around the second through hole 212. During the process of the agitator retracting, the material is evenly dropped along the cross-section of the feed baffle 21.

[0037] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the propulsion assembly 24 includes a second drive device 241, a rotating rod 242, a spiral blade 243, two actuating plates 244, multiple positioning rods 245, and a second material distribution plate 246.

[0038] The second material distribution plate 246 is mounted on the feed baffle 21 via multiple positioning rods 245 and is located below the feed baffle 21. The rotating rod 242 is rotatably connected to the second material distribution plate 246 via the second driving device 241, passes through the second through hole 212, and is located below the feed pipe 232. The spiral blade 243 is mounted on the rotating rod 242, and two actuating plates 244 are mounted on the rotating rod 242.

[0039] It should be noted that the second driving device 241 proposed in the above embodiment adopts a rotary motor. The second driving device 241 is housed in the cavity between the bottom wall of the feed pipe 232 and the first distribution plate 234. Multiple positioning rods 245 are set on the bottom wall of the feed baffle 21 to fix the position of the second distribution plate 246. The rotating rod 242 is set at the output end of the second driving device 241 and rotatably connected to the second distribution plate 246 to improve the rotational stability of the rotating rod 242. At the same time, the feed baffle 21 drives the propulsion assembly 24 and the feed pipe 232 to move up and down synchronously and adjust. The stable rotating rod 242 stably supports and synchronously rotates the two actuating plates 244 and the spiral blades 243 to maintain their rotational stability.

[0040] In one embodiment of this utility model, such as Figures 3-5 As shown, the buffer feed steel silo has two actuating plates 244 that are respectively curved and fit against the feed baffle 21.

[0041] It should be noted that the two actuating plates 244 described in this embodiment are arranged in opposite directions and are symmetrically distributed, but their bending directions are opposite, so that they can push and gather materials synchronously when rotating.

[0042] In summary, this utility model integrates dynamic volume adjustment, multi-level buffering, and mechanical guidance functions into one unit, enabling full control over the material from feeding to accumulation in the silo. It adjusts the volume of the feeding chamber in real time to adapt to different feeding rates. Simultaneously, it performs segmented buffering and material distribution, achieving multi-level buffering, actively gathering and dispersing the falling material, improving the uniformity of material distribution, reducing manual intervention, effectively reducing the labor intensity of workers, and improving the feeding buffering efficiency.
