Description

Technical Field

[0001] This utility model relates to the field of corn cob fermentation technology, specifically to an automatic stirring device for corn cob fermentation. Background Technology

[0002] Corn cobs are a rich source of agricultural waste, containing a large amount of cellulose, hemicellulose, and lignin. Through fermentation technology, corn cobs can be transformed into a variety of valuable products, such as biofuels, organic acids, and enzyme preparations. The fermentation process can effectively utilize the organic matter in corn cobs, realize resource recycling, reduce environmental pollution, and create certain economic benefits.

[0003] First, use a corn cob crushing device to put whole corn cobs into it. The crushing device uses high-speed rotating blades or grinding parts to crush the corn cobs into uniformly sized particles. Transfer the crushed corn cob particles to a mixing device. According to the fermentation process requirements, add a specific type and quantity of microbial inoculants. After the mixing device is started, the internal stirring blades begin to rotate, so that the corn cobs and microorganisms are fully mixed. Then, wrap the evenly mixed corn cob material with a material that is breathable and can effectively block external impurities. After wrapping, place the material in a sunny place. Utilize the heat generated by solar radiation to gradually warm the material inside the wrapping, providing suitable temperature conditions for fermentation.

[0004] Considering that after the corn cob and microbial community are thoroughly mixed by the mixing device, they need to be transferred to a separate molding device. This device uses a specific mold and extrusion mechanism to shape the material into a regular cylindrical shape. Considering that the transfer process between the mixing device and the molding device is cumbersome, it not only increases the cost of manual operation and time, but also easily causes material spillage and loss. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the traditional corn cob fermentation pretreatment requires mixing corn cobs and microbial flora with a stirring device and then transferring them to a separate molding device for shaping. This process involves multiple transfers, which is cumbersome, has high labor and time costs, and is prone to material spillage and loss. The present invention provides an automatic stirring device for corn cob fermentation.

[0006] To achieve the above objectives, this utility model provides an automatic stirring device for corn cob fermentation, including a support body, a connecting frame fixedly connected to the top of the support body, a crushing barrel fixedly installed in the inner cavity of the connecting frame, a driving device for crushing corn cobs connected to the inner wall of the crushing barrel via a rotating shaft, and a mixing and forming component provided at the bottom of the inner cavity of the connecting frame, the mixing and forming component being located directly below the crushing barrel for receiving the crushed corn cobs.

[0007] The mixing and molding assembly includes a spiral conveying roller and a molding barrel. The spiral conveying roller is used to mix the crushed corn cobs with microorganisms and convey them to the molding barrel. The molding barrel is used to stack the corn cobs into shape under the squeezing action of the spiral conveying roller.

[0008] The corn cob raw material and microorganisms are simultaneously crushed by the drive device. The crushing barrel completes the initial crushing. The mixing and molding component receives the crushed material. The spiral conveyor roller stirs and mixes the corn cob and microorganisms during the conveying process and pushes the material to the molding barrel. The corn cob is then extruded and shaped. This process simplifies the traditional multi-equipment step-by-step operation into an integrated process, improving processing efficiency.

[0009] As a further improvement to this technical solution, the surface of the crushing barrel is provided with multiple through slots, and the driving device can be composed of multiple staggered cutting blades. A feeding frame is fixedly connected to the inner cavity of the connecting frame. The feeding frame is located at the bottom of the crushing barrel and has a certain inclination angle. A feeding port is provided on the surface of the feeding frame. A feeding pipe is fixedly connected to the inner wall of the feeding port. A fixed cylinder is fixedly connected to the end of the feeding pipe away from the feeding port. The spiral conveying roller rotates on the inner wall of the fixed cylinder. A support frame is fixedly connected to the surface of the fixed cylinder. The bottom of the support frame is fixedly connected to the bottom of the inner cavity of the connecting frame. The end of the forming barrel is fixedly connected to the end of the fixed cylinder. A baffle is contacted at the end of the forming barrel away from the fixed cylinder. A telescopic device is fixedly connected to the surface of the connecting frame. The output end of the telescopic device is connected to the surface of the baffle. A drive motor is fixedly connected to the output end of the spiral conveying roller through the surface of the fixed cylinder. The drive motor is fixedly connected to the surface of the connecting frame.

[0010] The grooves on the surface of the crushing barrel, combined with the staggered cutting blades in the drive unit, allow the crushed corn cobs to pass through the grooves more evenly, improving the crushing effect and the uniformity of the output. The tilt angle of the feeding rack and the design of the feeding port guide the crushed corn cobs smoothly into the feeding pipe, avoiding material accumulation and ensuring smooth discharge. The feeding pipe connects the feeding port to the fixed cylinder, forming a stable material transmission channel and preventing material from spilling or deviating during transmission. The spiral conveying roller rotates inside the fixed cylinder, not only mixing the corn cobs with microorganisms evenly but also conveying the mixture to the forming barrel. The baffle initially blocks the material, allowing the corn cobs to accumulate and compact in the forming barrel. The telescopic device controls the movement of the baffle. After the corn cobs are formed, the telescopic device drives the baffle to separate from the forming barrel, so that the formed corn cobs can be smoothly discharged under the thrust of the spiral conveying roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this automatic mixing device for corn cob fermentation, the driving device crushes the corn cob raw materials and microorganisms, and the mixing and molding component directly receives and completes the mixing and molding, reducing intermediate transfer links, significantly shortening the production cycle, increasing the processing capacity per unit time, and effectively avoiding waiting and delays in the material transfer process. During the material conveying process, the spiral conveyor roller's spiral blades continuously stir, ensuring that the corn cob particles and microorganisms are fully and evenly mixed, providing good conditions for subsequent fermentation. Under the continuous extrusion of the spiral blades, the molding barrel gradually accumulates and compresses the material. As the pressure increases, the formed cylindrical material integrates crushing, mixing, and molding functions into one unit. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1-5As shown, this embodiment provides an automatic stirring device for corn cob fermentation, including a support body 1, a connecting frame 11 fixedly connected to the top of the support body 1, a crushing barrel 12 fixedly installed in the inner cavity of the connecting frame 11, a driving device 120 for crushing corn cobs connected to the inner wall of the crushing barrel 12 through a rotating shaft, and a mixing and forming component 2 provided at the bottom of the inner cavity of the connecting frame 11, the mixing and forming component 2 being located directly below the crushing barrel 12 for receiving the crushed corn cobs;

[0024] The mixing and molding assembly 2 includes a spiral conveying roller 22 and a molding barrel 24. The spiral conveying roller 22 is used to mix the crushed corn cobs with microorganisms and convey them to the molding barrel 24. The molding barrel 24 is used to stack the corn cobs into shape under the squeezing action of the spiral conveying roller 22.

[0025] The corn cob raw material and microorganisms fed into the crushing barrel 12 are simultaneously crushed by the drive device 120 to achieve a predetermined particle size. The crushed mixture falls into the mixing and molding component 2 through the discharge port at the bottom of the crushing barrel 12 under the action of gravity. The rotating blades of the spiral conveying roller 22 push the material towards the molding barrel 24. During the conveying process, the spiral blades of the spiral conveying roller 22 stir the material, so that the corn cob particles and microorganisms are fully mixed. The mixture enters the molding barrel 24 under the continuous push of the spiral conveying roller 22. Under the squeezing action of the spiral blades, the material gradually accumulates and compresses in the molding barrel 24. As the material is continuously input, the pressure in the molding barrel 24 continues to increase, so that the corn cob particles and microorganisms are tightly combined under high pressure, and finally form a cylindrical shape.

[0026] The improvement in this embodiment is as follows:

[0027] Considering that after the corn cob and microbial flora are thoroughly mixed by the mixing device, they need to be transferred to a separate molding device. This device uses a specific mold and extrusion mechanism to shape the material into a regular cylindrical shape. Considering that the transfer process between the mixing device and the molding device is cumbersome, it not only increases the cost of manual operation and time, but also easily causes material spillage and loss. Therefore, the corn cob raw material and microorganisms are crushed by the drive device 120, and the mixing and molding component 2 directly receives and completes the mixing and molding, reducing intermediate transfer links, significantly shortening the production cycle, increasing the throughput per unit time, and effectively avoiding waiting and delays in the material transfer process. During the material conveying process, the spiral conveyor roller 22 continuously stirs the spiral blades to ensure that the corn cob particles and microorganisms are fully and evenly mixed, providing good conditions for subsequent fermentation. Under the continuous extrusion of the spiral blades, the molding barrel 24 gradually accumulates and compresses the material. As the pressure increases, the formed cylindrical material integrates the functions of crushing, mixing and molding into one.

[0028] In order to ensure that the corn cobs cut by the driven device 120 can reach the mixing and molding component 2 evenly, multiple through slots are provided on the surface of the crushing barrel 12, and the driven device 120 can be composed of multiple staggered cutting blades. By providing multiple through slots on the surface of the crushing barrel 12, when the driven device 120 cuts the corn cobs, the high-speed rotating blades cut the corn cobs into small pieces. At this time, under the action of gravity, corn cobs of the appropriate size will be thrown out of the through slots and fall into the mixing and molding component 2.

[0029] In order to ensure that the corn cob can fall smoothly into the mixing and molding component 2 when it flies out of the through slot of the drive device 120, the inner cavity of the connecting frame 11 is fixedly connected to the feeding frame 13. The feeding frame 13 is located at the bottom of the crushing barrel 12. The feeding frame 13 has a certain inclination angle and the surface of the feeding frame 13 has a feeding port 130. After the corn cob is thrown out, it falls onto the surface of the feeding frame 13 and slides down along the inclined feeding frame 13 under the action of gravity. The feeding port 130 is opened on the surface of the feeding frame 13.

[0030] To ensure that the mixing and molding assembly 2 can smoothly receive the corn cobs discharged from the discharge port 130, a feed pipe 230 is fixedly connected to the inner wall of the discharge port 130. A fixed cylinder 23 is fixedly connected to the end of the feed pipe 230 away from the discharge port 130. The spiral conveying roller 22 rotates on the inner wall of the fixed cylinder 23. After the corn cobs are discharged from the discharge port 130 of the feeding rack 13, they directly enter the feed pipe 230 fixedly connected to the inner wall of the discharge port 130. The feed pipe 230 serves as a directional guide, accurately distributing the corn cobs... The corn cobs are conveyed into the fixed cylinder 23, which serves as the working carrier for the spiral conveying roller 22. Its internal space provides a temporary storage and mixing place for the corn cobs. When the spiral conveying roller 22 starts to rotate, the spiral structure on the surface of the roller generates a propulsive force. On the one hand, it fully mixes the corn cobs that have just entered the fixed cylinder 23 with the microorganisms that have been added before or subsequently. On the other hand, during the rotation, the spiral conveying characteristics are used to transport the evenly mixed corn cobs along the axial direction of the fixed cylinder 23 and gradually push them into the forming barrel 24.

[0031] In order for the spiral conveying roller 22 to rotate, a driving force needs to be provided to the spiral conveying roller 22. Therefore, a drive motor 21 is fixedly connected to the output end of the spiral conveying roller 22 through the surface of the fixed cylinder 23. The drive motor 21 is fixedly connected to the surface of the connecting frame 11. The operation of the drive motor 21 can drive the spiral conveying roller 22 to rotate in the inner cavity of the fixed cylinder 23.

[0032] In order to keep the fixed cylinder 23 stable in the inner cavity of the connecting frame 11, the fixed cylinder 23 needs to be supported. Therefore, a support frame 231 is fixedly connected to the surface of the fixed cylinder 23, and the bottom of the support frame 231 is fixedly connected to the bottom of the inner cavity of the connecting frame 11. By setting the support frame 231 to be fixedly connected to the bottom of the inner cavity of the connecting frame 11, the fixed cylinder 23 can be supported. At the same time, the surface of the support frame 231 matches the curvature of the surface of the fixed cylinder 23.

[0033] To enable the forming barrel 24 to receive and shape the corn cobs conveyed by the spiral conveyor roller 22, the end of the forming barrel 24 is fixedly connected to the end of the fixed cylinder 23. A baffle 240 is attached to the end of the forming barrel 24 away from the fixed cylinder 23. A telescopic device 25 is fixedly connected to the surface of the connecting frame 11, and the output end of the telescopic device 25 is connected to the baffle 240. When the spiral conveyor roller 22 rotates continuously inside the fixed cylinder 23, the axial thrust generated by its spiral structure continuously pushes the uniformly mixed corn cobs into the forming barrel 24. The end of the forming barrel 24 away from the fixed cylinder 23 is tightly fitted with the baffle 240, which is in contact with the baffle 240 at the initial start of the device. During this period, the baffle 240 acts as a material barrier. As the spiral conveyor roller 22 continues to rotate, corn cobs are continuously fed into the forming barrel 24. The material inside the barrel gradually accumulates and compacts. During this process, the baffle 240, due to its tight fit, firmly restricts the corn cobs from moving outward. After the corn cobs are fully compacted in the forming barrel 24 and achieve the expected forming effect, the telescopic device 25 on the surface of the connecting frame 11 is activated. The telescopic device 25 drives the baffle 240 to move upward through its output end, separating it from the port of the forming barrel 24 and releasing the obstruction restriction on the formed corn cobs. At this time, the thrust generated by the continuous operation of the spiral conveyor roller 22 is released, and the formed corn cobs are smoothly pushed out of the forming barrel 24.

[0034] In practical use, the automatic stirring device for corn cob fermentation of this utility model first involves feeding microorganisms and corn cobs into the crushing barrel 12 via the connecting frame 11. At this time, when the driving device 120 cuts the corn cobs, the high-speed rotating blades cut the corn cobs into small pieces. Under the action of gravity, corn cobs of the appropriate size are thrown out of the trough and fall onto the surface of the feeding rack 13. Under the action of gravity, they slide downwards along the inclined feeding rack 13. The feeding port 130 on the surface of the feeding rack 13 directly enters the feed pipe 230 fixedly connected to the inner wall of the feeding port 130. The feed pipe 230 plays a directional guiding role, accurately conveying the corn cobs into the fixed cylinder 23. The fixed cylinder 23 serves as the working carrier of the spiral conveying roller 22, and its internal space provides a temporary storage and mixing area for the corn cobs. When the spiral conveying roller 22 starts to rotate, the spiral structure on the surface of the roller generates propulsion force. On the one hand, the corn cobs that have just entered the fixed cylinder 23 are thoroughly mixed with the microorganisms that have been pre-added or added later. On the other hand, during the rotation, the spiral conveyor characteristics are used to transport the evenly mixed corn cobs along the axial direction of the fixed cylinder 23 and gradually push them into the forming barrel 24. As the spiral conveyor roller 22 continues to rotate, the corn cobs are continuously fed into the forming barrel 24, and the material in the barrel gradually accumulates and compacts. During this process, the baffle 240, with its tight fit, firmly restricts the corn cobs from moving outward. After the corn cobs are fully compacted in the forming barrel 24 and the expected forming effect is achieved, the telescopic device 25 on the surface of the connecting frame 11 is activated. The telescopic device 25 drives the baffle 240 to move upward through the output end, separating it from the port of the forming barrel 24 and releasing the obstruction restriction on the formed corn cobs. At this time, the thrust generated by the continuous operation of the spiral conveyor roller 22 is released, and the formed corn cobs are smoothly pushed out of the forming barrel 24.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
