Description

Technical Field

[0001] This invention relates to the field of feed fermentation, and more specifically to a storage and fermentation chamber for fermenting cattle feed. Background Technology

[0002] Fermented feed, through microbial fermentation, allows for better release and transformation of nutrients, making the protein, vitamins, and minerals in the feed more easily absorbed by cattle and sheep. Simultaneously, the abundant beneficial bacteria in fermented feed help regulate the gut microbiota of cattle and sheep, reducing harmful bacteria and thus promoting digestion and absorption. Furthermore, during fermentation, some indigestible components are broken down, allowing cattle to obtain more energy from the same amount of feed; some anti-nutritional factors present in natural feeds are degraded or neutralized during fermentation, further ensuring the high quality of the feed.

[0003] Existing methods for fermenting cattle feed in fermentation chambers have some drawbacks. For example, if the raw materials contain high moisture content, leachate is easily generated during fermentation. This leachate contains high levels of COD pollutants, so it needs to be both drained and properly treated; otherwise, it will affect the subsequent fermentation process. Additionally, corresponding inoculum strains need to be added during fermentation. However, in existing fermentation chambers, opening the inoculation port when adding inoculum allows cold outside air to enter, causing the indoor temperature to drop and affecting the fermentation effect. Summary of the Invention

[0004] The purpose of this invention is to provide a storage and fermentation chamber for fermenting cattle feed, thereby solving at least one of the above-mentioned technical problems.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A storage and fermentation chamber for fermented cattle feed, comprising:

[0007] The fermentation chamber has an opening at the top for adding inoculum; the opening is also equipped with a sealing mechanism to keep the fermentation chamber isolated from the outside during the process of adding inoculum.

[0008] Furthermore, the sealing mechanism includes a sliding shaft, an arc-shaped through groove is provided on the side wall of the fermentation chamber, a sealing groove is provided on the groove wall of the arc-shaped through groove, a folded sealing sheet is slidably connected in the sealing groove, the folded sealing sheet is sleeved and fixed on the sliding shaft, the sliding shaft is slidably installed on the arc-shaped through groove and one end of it extends out of the fermentation chamber as a handle;

[0009] The other end of the slide shaft is fixedly connected to an arc-shaped plate, which has multiple protrusions spaced apart. Each protrusion has an elastic strip, and the space between two adjacent protrusions serves as a material trough. The opening is designed as an arched structure, and the protrusions fit tightly against the arched surface of the opening.

[0010] Furthermore, the sealing mechanism also includes a shaking component with an opening located on one side of the top of the fermentation chamber. The shaking component is used to shake off the inoculated bacteria that have moved to the central area of ​​the fermentation chamber.

[0011] Furthermore, the shaking assembly includes a heart wheel, which is rotatably mounted at the end of the sliding shaft extending out of the fermentation chamber. An arc-shaped channel is fixedly provided on one side of the arc-shaped channel, and teeth are provided on the outer side of the heart wheel. The upper surface of the arc-shaped channel is roughened. The heart wheel rotates as it slides with the sliding shaft due to the friction between the teeth of the heart wheel and the roughened surface.

[0012] The thickness of the mandrel is greater than the width of the arc-shaped channel. A power transmission rod is set on the side of the mandrel away from the arc-shaped channel. A matching component is set in the fermentation chamber to link with the power transmission rod to impact the arc-shaped plate and shake off the inoculated bacteria in the feeding trough.

[0013] Furthermore, the supporting components include: a slide, an impact head, and a connecting rod. The connecting rod is configured as a gate-shaped structure with slides fixed at both ends. An arc-shaped groove is provided on the inner side wall of the fermentation chamber. Two slides are slidably connected in the corresponding arc-shaped grooves. Multiple impact heads are evenly arranged on the connecting rod. A first magnet is provided on the slide. An energy storage spring is provided at the bottom of the arc-shaped groove. The movement trajectories of the slide and the power transmission rod intermittently overlap. A second magnet is provided on the power transmission rod. The first magnet and the second magnet are magnetically attracted to each other.

[0014] Furthermore, when the slide shaft slides to two-fifths to three-fifths of the arc-shaped through groove, the movement trajectories of the slide block and the power transmission rod intermittently overlap, allowing the first magnet and the second magnet to exert magnetic force within their respective ranges.

[0015] Furthermore, a leachate discharge mechanism is provided at the bottom of the fermentation chamber. The leachate discharge mechanism includes a grid, which is located at the bottom of the fermentation chamber. A guide channel is provided at the bottom of the grid, and the guide channel is connected to a guide pipe. One end of the guide pipe is sealed to the guide channel, and the other end extends out of the fermentation chamber and is connected to a storage tank. A one-way valve is also provided on the guide pipe, and a manual valve and a flow observation window are provided in the middle of the guide pipe to control the discharge speed of the leachate and observe the flow status.

[0016] Furthermore, the depth of the guide channel gradually increases at one end of the guide pipe, making the guide channel inclined at 5°-10°.

[0017] The beneficial effects of this invention are:

[0018] This invention, through the setting of a sealing mechanism, on the one hand, uses a dynamic sealing design with convex ridges and elastic strips to block the intrusion of external bacteria, ensuring fermentation purity and reducing the risk of feed spoilage or fermentation failure; on the other hand, the inclined unloading and feeding trough structure enables quantitative and stepwise delivery of bacteria, simplifying operation, reducing contact, and the arc-shaped trajectory allows the bacteria to disperse naturally, which is conducive to uniform reproduction and improves fermentation efficiency and quality stability.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-5 As shown, the present invention is a storage and fermentation chamber for fermenting cattle feed, comprising:

[0028] Fermentation chamber 1 has an opening 2 at the top for adding inoculum; a sealing mechanism 3 is also provided at the opening 2 to keep fermentation chamber 1 isolated from the outside during the process of adding inoculum.

[0029] The sealing mechanism 3 includes a sliding shaft 31. An arc-shaped through groove 32 is provided on the side wall of the fermentation chamber 1. A sealing groove 33 is provided on the groove wall of the arc-shaped through groove 32. A folded sealing sheet 34 is slidably connected in the sealing groove 33. The folded sealing sheet 34 is sleeved and fixed on the sliding shaft 31. The sliding shaft 31 is slidably installed on the arc-shaped through groove 32 and one end of it extends out of the fermentation chamber 1 as a handle.

[0030] The other end of the sliding shaft 31 is fixedly connected to an arc plate 35. Multiple protrusions 36 are spaced apart on the arc plate 35. Elastic strips 37 are provided on the protrusions 36. The space between two adjacent protrusions 36 serves as a material trough 38. The opening 2 is set in an arched structure, and the protrusions 36 are tightly fitted to the arched surface of the opening 2.

[0031] In this invention, to reduce the likelihood of low-temperature air entering the room during feed fermentation and causing a drop in indoor temperature, thus affecting the fermentation effect, a sealing mechanism 3 is provided. During operation, the operator pushes the handle formed by the extended end of the sliding shaft 31 along the arc-shaped groove 32, causing the sliding shaft 31 and the arc-shaped plate 35 to move along a predetermined arc trajectory. This allows the auxiliary material of the mixed oil inoculated bacteria added from the opening 2 to enter the leftmost feeding trough 38 on the arc-shaped plate 35. As the arc-shaped plate 35 moves, the auxiliary material in the feeding trough 38 gradually slides to the left and enters the fermentation chamber 1 until it detaches from the arched surface at the opening 2. At this point, the feeding trough 3... The auxiliary material inside the 8th chamber is exposed inside the fermentation chamber 1. As the arc plate 35 continues to move, it changes from a top-bearing posture to a tilted posture on the left, allowing the auxiliary material to automatically detach from the material trough 38 and scatter on the raw materials inside the fermentation chamber 1. Since the arc plate 35 is provided with multiple protruding ribs 36 and elastic strips 37, the elastic strips 37 can enhance the sealing. After the leftmost material trough 38 moves away, the remaining protruding ribs 36 and elastic strips 37 are successively replenished, thereby forming leverage to ensure that at least one protruding rib 36 and elastic strip 37 are always kept in close contact on both sides of the opening 2, forming an isolation between the opening 2 and the internal fermentation chamber 1. This achieves the goal of keeping the fermentation chamber 1 as unaffected as possible by the external temperature during the inoculation process.

[0032] Through the aforementioned technical solution, on the one hand, the sealing mechanism 3 forms a dynamic seal through the continuous replenishment of the convex ribs 36 and the elastic strips 37, which can effectively prevent miscellaneous bacteria in the outside air from entering the fermentation chamber 1, reducing the risk of inoculated bacteria being contaminated and the impact of low external temperatures; at the same time, because the elastic strips 37 have good deformation capabilities, they can tightly fit the arched surface of the opening 2, and even during the movement of the arc plate 35, the sealing gap can be minimized, preventing miscellaneous bacteria from entering the fermentation environment with the airflow, ensuring the purity of the fermentation process, and reducing the problem of feed spoilage or fermentation failure caused by the growth of miscellaneous bacteria; on the other hand, the inclined unloading design of the arc plate 35 is combined with The structural features of the combined feeding trough 38 enable quantitative addition and step-by-step delivery of inoculated microorganisms. Workers only need to add an appropriate amount of auxiliary material to the opening 2 once, and it will automatically enter each feeding trough 38. By pushing the sliding shaft 31, multiple feeding troughs 38 can be controlled to unload material sequentially, eliminating the need to repeatedly open the sealing structure. This simplifies the operation process and reduces the chance of hand contact with the internal environment of the fermentation chamber 1. Simultaneously, the arc-shaped trajectory of the movement allows the auxiliary material to naturally disperse when leaving the feeding trough 38, avoiding concentrated accumulation. This creates favorable conditions for the uniform reproduction of microorganisms during subsequent fermentation, improving the overall efficiency and quality stability of feed fermentation.

[0033] The sealing mechanism 3 also includes a shaking component 39. The opening 2 is located on one side of the top of the fermentation chamber 1. The shaking component 39 is used to shake the inoculated bacteria that have moved to the middle area of ​​the fermentation chamber 1.

[0034] The shaking assembly 39 includes a heart wheel 391, which is rotatably mounted at the end of the slide shaft 31 that extends out of the fermentation chamber 1. An arc-shaped channel 392 is fixedly provided on one side of the arc-shaped through groove 32. A tooth 393 is provided on the outer side of the heart wheel 391. The upper surface of the arc-shaped channel 392 is roughened. The heart wheel 391 rotates as it slides with the slide shaft 31 due to the friction between the tooth 393 of the heart wheel 391 and the roughened surface.

[0035] The thickness of the heart wheel 391 is greater than the width of the arc-shaped channel 392. A power transmission rod 394 is provided on the side of the heart wheel 391 away from the arc-shaped channel 32. A matching component 4 is provided in the fermentation chamber 1 to link with the power transmission rod 394 to impact the arc-shaped plate 35 and shake off the inoculated bacteria in the feeding trough 38.

[0036] The cooperating component 4 includes: a slide 41, an impact head 42, and a connecting rod 43. The connecting rod 43 is configured as a gate-shaped structure and both ends are fixed with slides 41. An arc-shaped groove 44 is provided on the inner side wall of the fermentation chamber 1. Two slides 41 are slidably connected in the corresponding arc-shaped groove 44. Multiple impact heads 42 are evenly arranged on the connecting rod 43. A first magnet 45 is provided on the slide 41. An energy storage spring 46 is provided at the bottom of the arc-shaped groove 44. The movement trajectory of the slide 41 and the power transmission rod 394 intermittently overlaps. A second magnet 47 is provided on the power transmission rod 394. The first magnet 45 and the second magnet 47 are magnetically attracted to each other.

[0037] When the slide shaft 31 slides to two-fifths to three-fifths of the position of the arc-shaped through groove 32, the movement trajectory of the slide block 41 and the power transmission rod 394 intermittently coincides, so that the first magnet 45 and the second magnet 47 have a magnetic force action range.

[0038] In this invention, to improve the distribution effect of the inoculated strain, a shaking component 39 and a cooperating component 4 are provided. Through the cooperation of the shaking component 39 and the cooperating component 4, the purpose of rapid and uniform distribution of the inoculated strain is achieved. Specifically, when the arc-shaped plate 35 is moved by the sliding shaft 31, the teeth 393 on the outer surface of the core wheel 391 in the shaking component 39 interact with the rough surface on the arc-shaped channel 392. Utilizing the friction between the teeth 393 and the rough surface, the sliding shaft 31 drives the core wheel 391 to rotate as it moves. During this rotation, the core wheel 391 drives the power transmission rod 394 to move circumferentially. When the core wheel 391 moves to two-fifths to three-fifths of the arc-shaped through groove 32, the first magnet 45 and the second magnet 47 in the cooperating component 4... Within the range of magnetic force, when the power transmission rod 394 moves circumferentially again, it will drive the first magnet 45 and the slide 41 to move along the bottom of the arc-shaped groove 44 through magnetic force. Since the direction of movement of the second magnet 47 is consistent with the direction of the arc-shaped groove 44, the energy storage spring 46 will be compressed and stored until the second magnet 47 moves to a distance and the magnetic force weakens. Therefore, the energy storage spring 46 releases its elastic force instantly, pushing the first magnet 45, the slide 41 and the connecting rod 43 to reset along the arc-shaped groove 44. This process is repeated multiple times. The reciprocating motion of the connecting rod 43 drives the impact head 42 to impact and unload multiple material placement troughs 38 in sequence, so that the inoculum added on the right side moves to the middle area and is shaken off, achieving relatively uniform addition to the raw materials to improve the overall fermentation effect.

[0039] Through the aforementioned technical solution, on the one hand, the shaking component 39 and the sealing mechanism 3 form a dynamic linkage. Through the frictional rotation of the heart wheel 391 and the arc-shaped channel 392, the linear sliding of the sliding shaft 31 is converted into the circumferential motion of the power transmission rod 394. The conversion of motion mode allows the displacement action of the sealing mechanism 3 to directly drive the working of the cooperating component 4 without the need for an additional power source. At the same time, when the sliding shaft 31 drives the arc plate 35 to move to the middle of the fermentation chamber 1, the rotation of the heart wheel 391 just allows the power transmission rod 394 to enter the magnetic action range with the slide seat 41. With the magnetic attraction between the first magnet 45 and the second magnet 47, the continuous action of the sliding shaft 31 moving, the heart wheel 391 rotating, and the power transmission rod 394 being linked to the slide seat 41 to store force is realized. This makes the impact rhythm of the impact head 42 precisely match the unloading process of the arc plate 35, ensuring that the inoculated inoculum is impacted the moment it leaves the feeding trough 38, and avoiding the inoculum from sticking together. The residual bacteria are removed, improving the thoroughness of the shaking. On the other hand, the energy storage spring 46 in component 4 stores and releases energy, causing the impact head 42 to form a high-frequency reciprocating impact action. The dynamic force is transmitted to the feeding trough 38 through the arc plate 35. This not only shakes off the surface bacteria but also causes the feeding trough 38 to vibrate slightly, promoting the dispersion of the bacteria that have clumped in the trough. At the same time, the sliding trajectory of the slide seat 41 along the arc groove 44 is matched with the movement trajectory of the arc plate 35. The impact point of the impact head 42 changes synchronously with the movement of the arc plate 35, ensuring that each feeding trough 38 receives a targeted impact when it moves to the central area. Combined with the tilting posture of the arc plate 35, the shaken bacteria fall naturally along the arc trajectory and spread to the surroundings under the impact force. This works in conjunction with the dynamic sealing of the sealing mechanism 3 to isolate the external environment while achieving a uniform distribution of bacteria in the fermentation chamber 1, further improving fermentation efficiency.

[0040] The bottom of the fermentation chamber 1 is equipped with a leachate discharge mechanism 5, which includes a grid 51. The grid 51 is located at the bottom of the fermentation chamber 1, and a guide channel 52 is provided at the bottom of the grid 51. The guide channel 52 is connected to the guide pipe 53. One end of the guide pipe is sealed to the guide channel 52, and the other end extends out of the fermentation chamber 1 and is connected to a storage tank 54. A one-way valve is also provided on the guide pipe. A manual valve and a flow observation window are provided in the middle of the guide pipe to control the discharge speed of the leachate and observe the flow status. The depth of the guide channel 52 gradually increases at one end of the guide pipe, so that the guide channel 52 is inclined at 5°-10°.

[0041] In this invention, the leachate during the fermentation process is collected in a timely manner by the leachate discharge mechanism 5. First, the raw materials are isolated from the guide channel 52 by the grid 51 to reduce the possibility of the raw materials entering the guide channel 52. Then, the leachate flows out of the fermentation chamber 1 through the guide pipe and into the storage tank 54. The entire guide process can be controlled by a manual valve and observed through the flow observation window. The one-way valve is used to prevent backflow of the guide pipe. Through the aforementioned technical solution, the leachate is effectively treated.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
