Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a feed mixing device. Background Technology

[0002] In feed production and aquaculture applications, feed is typically composed of a variety of raw materials. These raw materials differ in nutritional composition and physical form. Direct use of these materials can fail to provide a balanced supply of nutrients, potentially leading to uneven growth and development, weakened immunity, and reduced aquaculture efficiency. Furthermore, uneven mixing can result in localized areas of excessive or insufficient nutrients. Therefore, mixing is essential to ensure thorough integration of the raw materials, creating a uniform feed product with consistent nutritional ratios to meet the demands for balanced and stable nutrition during aquaculture.

[0003] Currently, in pig feed mixing operations, due to the viscosity characteristics of the feed itself, the mixed material easily adheres to the inner wall surface of the mixing container. The internal structure of the mixing container is complex, and operators face space constraints during cleaning operations, making it difficult to thoroughly clean the structural dead corners and other areas on the inner wall of the mixing container. If the residual material is not effectively removed, it will directly cause cross-contamination of subsequent batches of feed, affecting the quality stability of feed products and the safety of breeding. Utility Model Content

[0004] The purpose of this invention is to provide a feed mixing device that addresses the problem in the prior art where feed easily adheres to the inner wall of the mixing container after mixing, leading to cross-contamination of subsequent feeds. This device provides a solution to the problem of efficient cleaning of the container's interior without dead corners, thus preventing cross-contamination of subsequent batches of feed.

[0005] This utility model is achieved through the following technical solution:

[0006] A feed mixing device includes: a frame; a mixing container mounted on the frame; two end plates respectively mounted on both sides of the mixing container; a rotating main shaft rotatably mounted between the two end plates; a mixing assembly mounted on the outer wall of the rotating main shaft; an isolation liner adapted to the interior of the mixing container, the isolation liner being detachably embedded in the mixing container, and clearance notches being provided on both sides of the isolation liner; and a drive assembly mounted on the frame and drivingly connected to the rotating main shaft; wherein, when the isolation liner is embedded in the mixing container, the rotating main shaft passes through the two clearance notches to form a clearance fit; the isolation liner can rotate around the rotating main shaft to the outside of the mixing container, thereby separating the isolation liner from the rotating main shaft.

[0007] Furthermore, in this invention, gap baffles are detachably installed on both sides of the two end plates; the gap baffles can be embedded in the gap between the mixing container and the isolation liner to restrict the isolation liner from detaching from the mixing container.

[0008] Furthermore, in this utility model, limit slots are respectively opened on opposite sides of the end plate, and an assembly channel is opened on the inner wall of the limit slot, and a limit component is installed in the assembly channel; wherein, when the gap baffle is embedded in the limit slot, the limit component can limit the gap baffle to the limit slot.

[0009] Furthermore, in this utility model, the aforementioned limiting component includes: a limiting pin, which is movably inserted into the assembly channel; and an elastic member, which is disposed in the assembly channel, with one end of the elastic member connected to the inner wall of the assembly channel and the other end of the elastic member connected to the limiting pin; wherein, in its natural state, the limiting pin can at least partially extend out of the assembly channel.

[0010] Furthermore, in this utility model, a guide structure is provided at the end of the limiting pin away from the elastic element; wherein, when the gap baffle enters the limiting slot, the gap baffle can cooperate with the guide structure.

[0011] Furthermore, in this utility model, the bottom end of the mixing container is provided with a first discharge port; the bottom end of the isolation liner is provided with a second discharge port, and a discharge pipe is detachably installed at the second discharge port, which can overlap with the first discharge port.

[0012] Furthermore, in this invention, the aforementioned drive assembly includes a drive motor; the drive motor is mounted on the frame, and the output end of the drive motor is connected to the rotating spindle.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] 1. This utility model combines a detachable isolation liner with a clearance fit structure with a rotating main shaft, and a fully exposed disassembly and assembly mechanism in which the isolation liner rotates around the rotating main shaft. This eliminates the drawbacks of cross-contamination caused by incomplete cleaning of residues on the inner wall of traditional fixed mixing containers, avoids feed quality risks and batch rework losses caused by dead corner residues, and significantly improves the cleanliness of feed mixing operations and batch production stability.

[0015] 2. The present invention features a coaxial fit between the isolation liner and the mixing container; it overcomes the limitations of interference between the isolation liner and the stirring components during the traditional mixing process, and achieves full positioning of the isolation liner and interference-free operation of the mixing components, significantly improving the uniformity of feed mixing and the reliability of equipment operation.

Detailed Implementation

[0025] 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 embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0026] Example

[0027] Please refer to Figures 1 to 6This utility model provides a feed mixing device. It includes a frame 1, a mixing container 2, end plates 3, a rotating main shaft 4, a mixing component 5, an isolation liner 8, and a drive assembly. The mixing container 2 is fixedly installed on the frame 1, and its interior is a cylindrical cavity. Two end plates 3 are respectively located at both ends of the mixing container 2. The rotating main shaft 4 is rotatably assembled via the two end plates 3. One end of the rotating main shaft 4 is partially attached to the inner wall of the mixing container 2 and partially connected to the end plates 3, while the other end of the rotating main shaft 4 partially passes through the mixing container 2 and partially through the end plates 3, ensuring that the rotating main shaft 4 is positioned on the central axis of the mixing container 2. The mixing component 5 is installed on the outer wall of the rotating main shaft 4. The isolation liner 8 is adapted to the inner cavity of the mixing container 2 and is detachably embedded within the mixing container 2. The isolation liner 8 has clearance notches 10 at both ends. The drive assembly is mounted on the frame 1 and is connected to the rotating main shaft 4 via a transmission connection.

[0028] When the isolation liner 8 is installed in the mixing container 2, the rotating main shaft 4 passes through the clearance notch 10 and forms a clearance fit. The central axis of the isolation liner 8 and the mixing container 2 are collinear. The isolation liner 8 can fit against the inner wall of the mixing container 2 to eliminate shaking. After feed is put into the isolation liner 8, the drive component drives the rotating main shaft 4 to rotate. The mixing component 5 moves synchronously with the rotating main shaft 4 to realize the mixing operation of the feed in the isolation liner 8. After the mixing is completed, the feed can be directly taken out.

[0029] After long-term operation, the inner wall of the isolation liner 8 may be prone to material residue or wear, requiring cleaning or maintenance. After releasing the connection constraint between the isolation liner 8 and the mixing container 2, the isolation liner 8 can be rotated around the main shaft 4. Once the isolation liner 8 is rotated outside the mixing container 2, the isolation liner 8 can be removed for subsequent cleaning or maintenance operations.

[0030] It should be noted that the inner cavity of the mixing container 2 is a semi-cylindrical cavity, and the structure of the isolation liner 8 is adapted to the inner cavity of the mixing container 2, also adopting a semi-cylindrical cavity design; this adaptation structure provides the isolation liner 8 with rotational freedom relative to the mixing container 2, ensuring that the isolation liner 8 can rotate along the corresponding axis.

[0031] The mixing container 2 is equipped with a movable cover that can be rotated on the side. During mixing, the movable cover can be rotated to close the top of the mixing container 2. At this time, the movable cover and the mixing container 2 form a complete cylindrical structure, which can prevent feed from spilling during mixing. When it is necessary to remove the feed or disassemble the isolation liner 8, the movable cover can be rotated in the opposite direction to open the top of the mixing container 2.

[0032] Please refer to Figure 2 and Figure 3In some embodiments of this application, gap baffles 9 are detachably mounted on the opposite inner sides of the two end plates 3; the gap baffles 9 are embedded in the gap between the mixing container 2 and the isolation liner 8 to restrict the isolation liner 8 from detaching from the mixing container 2. When the isolation liner 8 is embedded in the mixing container 2 and fits against the inner wall of the mixing container 2, the gap baffles 9 can be used to limit the isolation liner 8, preventing displacement of the isolation liner 8 during the mixing operation and ensuring the normal operation of the mixing operation.

[0033] The two end plates 3 each have a limiting groove 11 on their opposite sides that is adapted to the gap baffle 9. The inner wall of the limiting groove 11 has an assembly channel 13, in which a limiting component is assembled. When assembling the gap baffle 9, the two ends of the gap baffle 9 are inserted into the limiting grooves 11 on the same side of the two end plates 3. The limiting component simultaneously locks and limits the gap baffle 9, so that the gap baffle 9 is embedded in the gap between the mixing container 2 and the isolation liner 8, thereby achieving anti-detachment constraint on the isolation liner 8.

[0034] Please refer to Figure 4 Specifically, the limiting component includes a limiting pin 12 and an elastic element 14. The limiting pin 12 is movably inserted into the assembly channel 13, and the elastic element 14 (spring) is disposed inside the assembly channel 13. One end of the elastic element 14 is connected to the inner wall of the assembly channel 13, and the other end is connected to the limiting pin 12. The assembly channel 13 can be opened at the top of the limiting slot 11. When the elastic element 14 is in its natural state, the limiting pin 12 extends at least partially out of the assembly channel 13 and into the limiting slot 11. The limiting pin 12 and the inner wall of the limiting slot 11 cooperate to form a locking and limiting position on the gap baffle 9. When it is necessary to remove the gap baffle 9, the operator pushes the limiting pin 12 into the assembly channel 13, causing the limiting pin 12 to fully retract into the assembly channel 13. Simultaneously, the elastic element 14 undergoes compression deformation, releasing the limiting constraint on the gap baffle 9.

[0035] Please refer to Figure 4 In some embodiments of this application, a guide structure 15 is provided at the end of the limiting pin 12 away from the elastic member 14; when the gap baffle 9 is inserted into the limiting slot 11, the gap baffle 9 and the guide structure 15 form a guiding engagement. Specifically, during the insertion process, the gap baffle 9 contacts the guide structure 15, and the thrust it applies is decomposed by the guide structure 15 to form a component force toward the assembly channel 13. This component force can drive the limiting pin 12 to retract completely into the assembly channel 13, so that the assembly of the gap baffle 9 can be completed without the operator manually pushing the limiting pin 12, thus improving the ease of operation.

[0036] It should be noted that the surface of the gap baffle 9 is provided with an elastic layer. When the gap baffle 9 is embedded in the gap between the mixing container 2 and the isolation liner 8, the elastic layer is compressed and deformed. This not only fills the assembly gap between the gap baffle 9 and the mating surface, but also forms an elastic compression constraint on the gap baffle 9, thereby preventing the gap baffle 9 from shaking during the mixing operation.

[0037] Please refer to Figure 5 and Figure 6 In some embodiments of this application, the bottom end of the mixing container 2 is provided with a first discharge port 16, and the bottom end of the isolation liner 8 is provided with a corresponding second discharge port 17. A discharge pipe 7 is detachably mounted at the second discharge port 17, and the second discharge port 17 can overlap with the first discharge port 16. After the mixing operation is completed, opening the discharge pipe 7 allows the material to enter through the second discharge port 17 and then be discharged and collected through the discharge pipe 7. When it is necessary to disassemble the isolation liner 8, first disassemble the discharge pipe 7 from the second discharge port 17, then remove the discharge pipe 7 from the first discharge port 16 to eliminate interference, and then the isolation liner 8 can be rotated to complete the disassembly operation.

[0038] The detachable connection between the discharge pipe 7 and the second discharge port 17 can be achieved using conventional mechanical structures, specifically threaded or snap-fit ​​structures. If a threaded connection structure is used, internal threads can be machined on the inner wall of the second discharge port 17, and corresponding external threads can be machined on the outer wall of the discharge pipe 7. If a snap-fit ​​structure is used, elastic claws can be provided on the inner wall of the second discharge port 17, and an annular groove can be opened at the corresponding position of the discharge pipe 7. During assembly, the elastic claws are inserted into the annular groove to form a clamping and fixing. During disassembly, the elastic claws are pressed to disengage from the annular groove, and the discharge pipe 7 can be removed from the second discharge port 17.

[0039] The discharge pipe 7 is equipped with a valve. The valve can adopt an elastic plug structure, which can completely fill the inner cavity of the discharge pipe 7 to achieve material sealing and prevent leakage. When discharging, the elastic plug can be removed to allow the material to be discharged along the discharge pipe 7. In addition, the valve can also adopt a simple opening and closing structure commonly used in the mechanical field, such as a flip-top valve, in which a flip-top is hinged to the inner wall of the discharge pipe 7. The flip-top forms a seal against the inner wall of the discharge pipe 7 by its own weight or torsion spring. When discharging, flipping the flip-top opens the channel. Alternatively, a slide gate valve structure can be used, in which a slot is opened on the side wall of the discharge pipe 7. A slide gate is inserted into the discharge pipe 7 along the slot to block the material channel. The slide gate can be pulled out to allow the material to be discharged, which is suitable for the use needs of feed unloading scenarios.

[0040] For example, the mixing component 5 is mounted on the outer wall of the rotating main shaft 4 and can adopt a multiple mixing blade structure. The multiple mixing blades are arranged along the axial direction of the rotating main shaft 4. When the rotating main shaft 4 rotates, it drives the mixing blades to rotate synchronously. The mixing of feed in the isolation liner 8 is achieved by the mixing blades stirring. In addition, the mixing component 5 can also be a spiral stirring and conveying blade. The spiral stirring and conveying blade is installed on the rotating main shaft 4. When the rotating main shaft 4 rotates, it drives the spiral stirring and conveying blade to rotate synchronously, which can realize both the mixing of feed and the function of feed conveying. During the mixing operation, the spiral stirring and conveying blade can be driven to move the feed back and forth along the axial direction by controlling the forward and reverse rotation of the rotating main shaft 4. The mixing effect is enhanced during the back-and-forth conveying process. After the mixing is completed, the valve corresponding to the discharge pipe 7 is opened to control the rotating main shaft 4 to rotate in one direction, so that the spiral stirring and conveying blade conveys the feed to the discharge pipe 7 to complete the discharge operation.

[0041] The mixing component 5 can also adopt a double helical belt structure, with two helical belts rotating in opposite directions installed on the rotating main shaft 4. When the rotating main shaft 4 is running, the forward-rotating helical belt drives the feed to one end, and the reverse-rotating helical belt synchronously drives the feed to the other end. The opposing conveying forces formed by the two cause the feed to tumble back and forth along the axial direction in the isolation liner 8, and the mixing effect is enhanced through shearing and convection.

[0042] It should be noted that the inner cavity contour dimensions of the isolation sleeve 8 are designed to match the outer dimensions of the mixing component 5. The inner cavity space of the isolation sleeve 8 is larger than the space occupied by the mixing component 5, ensuring that the isolation sleeve 8 maintains a preset safe gap with the mixing component 5 during rotation, thus avoiding motion interference.

[0043] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
