Description

Technical Field

[0001] This utility model relates to an anti-arching structure for feed silos, belonging to the field of feed processing technology. Background Technology

[0002] In the field of feed processing and storage, traditional feeding systems mostly rely on gravity-driven natural feeding or single-auger conveyor structures. Their fundamental flaw lies in the lack of an active intervention mechanism to prevent the deterioration of the material's cohesion. Since feed raw materials generally have hygroscopic and agglomerating properties, they are easily affected by temperature and humidity changes during storage, leading to the formation of a stable adhesive force field between particles. This results in a frequent "arching effect" in the conical section of the silo: when the internal friction angle of the material exceeds the inclination angle of the silo wall, the particles interlock to form an arched support structure, severely hindering material flow. Therefore, an anti-arching structure for feed silos is proposed. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide an anti-arching structure for feed silos, which eliminates the formation of arched structures caused by the adhesion of the silo walls, and keeps the materials in a loose and fluidized state, ensuring the continuity and stability of the discharge process.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides a feed silo anti-arching structure, comprising:

[0005] A storage bin, wherein the lower end of the storage bin is provided with a discharge port and the upper end of the storage bin is provided with a bin cover;

[0006] A central rod, which rotates in the middle of the storage bin, with its lower end extending into the interior of the discharge port;

[0007] Screw blade one, the screw blade one is disposed inside the discharge port and fixed to the lower end of the central rod;

[0008] The central rod is equipped with multiple stirring rods to prevent material from bridging.

[0009] Preferably, a fixed sleeve is fixed to the lower end of the central rod, the lower ends of multiple stirring rods are connected to the fixed sleeve, a movable sleeve is connected to the upper end of the central rod, multiple connecting rods are connected to the movable sleeve, and the ends of the multiple connecting rods away from the movable sleeve are connected to the upper ends of the corresponding stirring rods.

[0010] Preferably, the movable sleeve slides upward or downward along the axis of the central rod on the central rod;

[0011] in:

[0012] The lower end of the stirring rod is rotatably connected to the fixed sleeve;

[0013] The connecting rod is rotatably connected to the movable sleeve;

[0014] The stirring rod is rotatably connected to the connecting rod.

[0015] Preferably, the outer end face of the stirring rod is uniformly fixedly connected with a plurality of pressure plates for pressing the material downward.

[0016] Preferably, a hydraulic cylinder is fixedly connected to the side wall of the compartment cover, the lower end of the hydraulic cylinder passes through the compartment cover and is connected to a shift fork, and an annular groove is formed on the side wall of the movable sleeve, with the shift fork inserted into the annular groove.

[0017] Preferably, a spline block is fixed on the side wall of the central rod along the axial direction of the central rod, and a keyway adapted to the spline block is provided on the movable sleeve.

[0018] Preferably, a motor for driving the central rod to rotate is fixedly installed on the compartment cover.

[0019] Preferably, a conveying pipe is horizontally arranged below the storage silo, one end of the conveying pipe is connected to the discharge port, and the other end of the conveying pipe is provided with a discharge port;

[0020] The conveying pipe is internally connected to a screw conveyor blade via a motor.

[0021] Preferably, the silo cover is provided with an injection port for injecting materials into the storage silo.

[0022] Preferably, the storage silo is provided with a support frame.

[0023] Compared with existing technologies:

[0024] 1. When the central rod is driven to rotate by the motor, the auger blades at the lower end generate axial propulsion force, pushing the material to be discharged in an orderly manner along the spiral channel; the stirring rod in the middle section generates radial disturbance, continuously cutting the material accumulation layer, and disrupting the balance of adhesion and static friction between particles. This not only eliminates the formation of arched structures caused by the adhesion of the bin wall, but also keeps the material in a loose fluidized state, ensuring the continuity and stability of the discharge process.

[0025] 2. This invention utilizes the continuous rotation of multiple auger blades to form a bottom material conveying channel, while the periodic oscillation of the stirring rod driven by the movable sleeve generates radial shear force in the middle layer. Combined with the pulsed pressing action of the pressure plate, a dynamic mixing field is formed within the silo. This composite motion mode effectively disrupts the balance of adhesion and friction between materials, keeping the feed particles in a loose, fluidized state. Attached Figure Description

[0041] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0042] Example 1

[0043] like Figures 1-6 As shown in this embodiment, a feed silo anti-arching structure is provided, including a storage silo 1, a discharge port 101 at the lower end of the storage silo 1, and a silo cover 102 at the upper end of the storage silo 1; a central rod 2 is rotatably connected to the middle of the storage silo 1, and a motor 10 for driving the central rod 2 to rotate is fixedly installed on the silo cover 102. The output shaft of the motor 10 is connected to the upper end of the central rod 2, and the lower end of the central rod 2 extends into the interior of the discharge port 101; an auger blade 3 is provided inside the discharge port 101, and the auger blade 3 is fixed to the lower end of the central rod 2; wherein, a plurality of stirring rods 4 for preventing material arching are provided on the central rod 2.

[0044] Work process:

[0045] When the storage silo 1 needs to discharge material, the motor 10 at the top of the silo cover 102 starts, driving the central rod 2 to rotate at a set speed. The auger blade 3 at the lower end of the central rod 2 rotates with the rod, and its spiral surface forms a propulsion channel with the inner wall of the discharge port 101, pushing the material at the bottom of the silo axially to the discharge port 101. At the same time, multiple stirring rods 4 distributed in the middle section of the central rod 2 generate radial disturbances during rotation, continuously cutting the material accumulation layer and disrupting the balance of adhesion and friction between feed particles. This effectively prevents the material from forming a stable arched structure on the silo wall, ensuring that the feed is discharged in a continuous flow.

[0046] The cover 102 is provided with a filling port 103 for injecting materials into the storage bin 1.

[0047] A support frame 16 is installed on the storage silo 1.

[0048] Example 2

[0049] like Figures 1-4 As shown, based on Embodiment 1, in this embodiment, the lower end of the central rod 2 is fixed with a fixed sleeve 5, the lower ends of multiple stirring rods 4 are connected to the fixed sleeve 5, the upper end of the central rod 2 is connected with a movable sleeve 6, multiple connecting rods 7 are connected to the movable sleeve 6, and the ends of the multiple connecting rods 7 away from the movable sleeve 6 are connected to the upper ends of the corresponding stirring rods 4.

[0050] The movable sleeve 6 slides up or down along the axis of the central rod 2; wherein: the lower end of the stirring rod 4 is rotatably connected to the fixed sleeve 5; the connecting rod 7 is rotatably connected to the movable sleeve 6; the stirring rod 4 and the connecting rod 7 are rotatably connected.

[0051] Multiple pressure plates 401 for pressing materials downward are evenly fixedly connected to the outer end face of the stirring rod 4.

[0052] A hydraulic cylinder 8 is fixedly connected to the side wall of the compartment cover 102. The lower end of the hydraulic cylinder 8 passes through the compartment cover 102 and is connected to a shift fork 9. An annular groove 601 is provided on the side wall of the movable sleeve 6, and the shift fork 9 is inserted into the inside of the annular groove 601.

[0053] A spline block 201 is fixed on the side wall of the center rod 2 along the axial direction of the center rod 2, and a keyway 602 adapted to the spline block 201 is provided on the movable sleeve 6.

[0054] Work process:

[0055] When the system starts, the central rod 2 rotates continuously under the drive of motor 10, and the auger blades 3 push the material axially. Simultaneously, the piston rod of the hydraulic cylinder 8 extends, driving the movable sleeve 6 downwards along the spline structure via the shift fork 9. During this process, the connecting rod 7 converts the vertical movement of the movable sleeve 6 into the radial oscillation of the stirring rod 4—when the movable sleeve 6 moves downwards, the connecting rod 7 pushes the upper end of the stirring rod 4 towards the bin wall, and the pressure plate 401 presses down on the material layer; when the hydraulic cylinder 8 retracts, the movable sleeve 6 moves upwards, and the stirring rod 4 returns to its original position. This periodic oscillation, combined with the rotation of the central rod 2, forms a mixing field, disrupting the material's cohesion and effectively preventing the material from forming a stable arched structure on the bin wall, ensuring that the feed is discharged in a continuous flow.

[0056] Example 3

[0057] like Figure 1 , Figure 2 and Figure 4 As shown, based on the above embodiments, in this embodiment, a conveying pipe 11 is horizontally arranged below the storage bin 1. One end of the conveying pipe 11 is connected to the discharge port 101, and the other end of the conveying pipe 11 is provided with a discharge port 12.

[0058] The conveying pipe 11 is connected to the screw conveyor blade 14 by a motor 13.

[0059] When motor 13 starts, auger blade 14 conveys the material in conveying pipe 11 from the end near the discharge port 101 to the discharge port 12.

[0060] In addition, such as Figure 5 As shown, the discharge port 101 is provided with a support plate 15 for supporting the lower end of the center rod 2. When the conveying pipe 11 is installed below the storage bin 1, the support plate 15 is installed and fixed simultaneously.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model.
