Description

Technical Field

[0001] This application relates to the technical field of the fermentation preparation of biological fertilizers, and particularly relates to a device and process for the fermentation preparation of biological fertilizers. Background Art

[0002] Biological fertilizers play an extremely important role in agricultural production. They can effectively improve soil quality and promote crop growth. The development of microbial fermentation technology has provided new possibilities for the preparation of biological fertilizers. Through specific culture conditions and the selection of microbial strains, reacting with waste materials (such as straw, animal manure, etc.) can produce a large amount of biological fertilizers in a relatively short time, not only improving the effectiveness of the fertilizers, but also significantly enhancing their stability and application scope.

[0003] In order to facilitate the full contact between straw and microorganisms, the straw is often crushed before the reaction. For example, the patent application with the publication number CN116655414A discloses a device for preparing waste straw fermentation fertilizer, which mainly consists of a bottom plate, a crushing box and a fermentation box. The top of the crushing box is provided with a feeding port and equipped with a two-stage pretreatment mechanism: the upper crushing component initially crushes the straw, and the lower flattening component further flattens the crushed material through a dividing inclined plate to increase the contact area of the material and shorten the subsequent fermentation cycle. This device significantly improves the straw decomposition efficiency through combined crushing-flattening pretreatment.

[0004] However, there are still the following problems when using the above prior art to crush straw: The above prior art can perform roll crushing on straw. Although it can flatten and crush it, it does not completely destroy the fiber bundle structure of the straw, resulting in the interior of the straw not being fully exposed to the outside, affecting the subsequent contact area between the straw and microorganisms, and thus affecting the preparation rate of biological fertilizers.

[0038] The following is combined with Figures 1 to 7 This application is described in further detail.

[0039] The embodiments of the present application disclose a bio-fertilizer fermentation preparation device and process, which can strip the straw into multiple structures during the straw processing process, thereby completely destroying the fiber bundle structure of the straw, exposing the interior of the straw to the outside, increasing the contact area between the straw and the microbial strains, and thus improving the bio-fertilizer preparation rate.

[0040] Example 1:

[0041] Reference Figure 1 as well as Figure 2, a device for fermenting and preparing biological fertilizers, including a processing frame 1 with an upward opening and a U-shaped structure. A conveying mechanism 2 is commonly installed on the two vertical sections of the processing frame 1, and a crushing mechanism 3 is installed inside the processing frame 1. The crushing mechanism 3 includes:

[0042] Rotating shafts 31 are symmetrically arranged along the depth direction of the processing frame 1, and a rubber belt 32 is commonly installed between the two rotating shafts 31.

[0043] Fixed frames 33 are provided at both ends of the rotating shaft 31, and the rotating shaft 31 is installed on the fixed frame 33 through bearings.

[0044] Multiple groups of stripping rods 34 are evenly arranged along the width direction of the rubber belt 32. Each group of stripping rods 34 is evenly arranged with a plurality of them along the length direction of the rubber belt 32 and is used for stripping the straw.

[0045] During the movement of the stripping rods 34, the straw can be stripped. And each time it is stripped, the straw rotates a certain angle. Thus, during the process of treating the straw by the stripping rods 34, the straw can be stripped into multiple strips, and then the stripping rods 34 can completely destroy the fiber bundle structure of the straw, making the inside of the straw exposed to the outside, increasing the contact area between the straw and the microbial strains, and thereby improving the preparation rate of biological fertilizers.

[0046] Refer to Figure 3 and Figure 4 , the conveying mechanism 2 includes:

[0047] Two support frames 21 are provided and are respectively installed on the two vertical sections of the processing frame l. A conveying rack 22 is commonly installed between the two support frames 21.

[0048] Conveying rollers 23 are installed at the four corners of the bottom of the conveying rack 22 through bearings. A conveyor belt 24 for conveying the straw is commonly installed between two adjacent conveying rollers 23 along the length direction of the conveying rack 22.

[0049] Two groups of pressing shafts 25 are symmetrically installed at the bottom of the conveying rack 22 along its width direction, and the pressing shafts 25 are evenly distributed along the length direction of the conveying rack 22 and are used for pressing and limiting the conveyor belt 24. [[ID=二十九]] [[ID=三十]]

[0050] The stripping rod 34 and the rubber belt 32 are located below any group of conveyor rollers 23, and one end of the stripping rod 34 close to the two conveyor belts 24 coincides with the gap between the two conveyor belts 24 to ensure that the stripping rod 34 can strip the straw between the two conveyor belts 24 during movement. During specific operation, the conveyor roller 23 close to the side of the stripping rod 34 is driven to rotate by an external driving force (a motor, etc., not shown in the figure). The conveyor belt 24 is driven to move during the rotation of the conveyor roller 23. At this time, the straw is placed between the two conveyor belts 24 in turn. The moving conveyor belt 24 cooperates with the stationary conveyor belt 24 to drive the straw to move intermittently into the processing frame 1, that is, every time the straw moves a certain distance into the processing frame 1, the moving conveyor belt 24 stops for a while to ensure that the stripping rod 34 can fully strip the straw.

[0051] During the period when the moving conveyor belt 24 stops, the rotating shaft 31 is driven to rotate by an external driving force (motor, etc., not shown in the figure). During the rotation of the rotating shaft 31, the rubber belt 32 is driven to move. During the movement of the rubber belt 32, the stripping rod 34 is driven to move along the depth direction of the processing frame 1, and then the stripping rod 34 can strip the straw, so that the straw is stripped into a strip structure.

[0052] It should be noted that the rubber belt 32 is divided into a stripping part and an empty return part. The stripping part is equipped with a stripping rod 34, and the empty return part is not equipped with a stripping rod 34. Moreover, every time the rotating shaft 31 drives the rubber belt 32 to move a certain distance, the stripping part of the rubber belt 32 is completely facing the straw or the empty return part of the rubber belt 32 is completely facing the straw.

[0053] After the stripping rod 34 has stripped the straw once, the rotating shaft 31 rotates to drive the stripping part of the rubber belt 32 to leave the straw, and the empty return part of the rubber belt 32 faces the straw. At this time, the moving conveyor belt 24 continues to work to drive the straw to continue moving. Since the empty return part of the rubber belt 32 gives way, the straw will not collide with the stripping rod 34 during the movement. At this time, the moving conveyor belt 24 and the stationary conveyor belt 24 cooperate with each other to drive the straw to rotate synchronously by a certain angle during the movement of the straw, and then the rotating shaft 31 continues to rotate to drive the stripping part of the rubber belt 32 to move toward the side of the straw. During the movement of the rubber belt 32, the stripping rod 34 strips the straw.

[0054] By repeating the above-mentioned actions, the moving straw can be stripped so that the straw has a strip structure. Therefore, the stripping rod 34 can completely destroy the fiber bundle structure of the straw, exposing the inside of the straw to the outside, increasing the contact area between the straw and the microbial strains, thereby improving the biofertilizer preparation rate.

[0055] The extrusion shaft 25 can play an extrusion and limiting role on the conveyor belt 24 to ensure the friction between the conveyor belt 24 and the straw, thereby ensuring that the conveyor belt 24 will not easily fall off the conveyor belt 24 during the conveying of straw and the stripping process of the straw.

[0056] Reference Figure 4 In order to further ensure the straw conveying effect, a plurality of rubber strips 241 are evenly arranged on the conveyor belt 24 along its width direction, and the rubber strips 241 on the two conveyor belts 24 are staggered along the width direction of the conveyor belt 24.

[0057] During specific operation, the conveyor belt 24 adopts an array of staggered rubber strips 241 to form a serrated meshing structure, which generates vertical constraint force and lateral friction force, so that the straw is in closer contact with the conveyor belt 24 when conveying the straw, further reducing the possibility of the straw falling during conveying and stripping the straw.

[0058] Reference Figure 5 During the stripping process, the straw strip structure will be broken due to the large rigid pulling force of the stripping rod 34. The feeding belt 12 provided by the present invention can collect and transport the broken straw strip structure. Specifically, the processing frame 1 is provided with rotating shafts 11 symmetrically arranged along its length direction, and the feeding belt 12 is installed between the rotating shafts 11.

[0059] During specific operation, when stripping the straw, the rotating shaft 11 is driven to rotate by an external drive (motor, etc., not shown in the figure), and the feeding belt 12 is driven to move during the rotation of the rotating shaft 11. During the movement of the feeding belt 12, the broken straw can be collected and transported to the outside of the processing frame 1 and collected, so as to prevent the broken straw from falling to the bottom of the processing frame 1 and causing the accumulation of straw.

[0060] Reference Figure 5 as well as Figure 6 Since the straw fibers are subjected to shear force during the stripping process, electrostatic adsorption and mechanical entanglement are generated, causing the fibers to adhere to the surface of the stripping rod 34. The periodic movement of the reciprocating push plate 321 can achieve fiber stripping through the following mechanism. Specifically, a plurality of push plates 321 are evenly arranged along the width direction of the rubber belt 32 on one side of the rubber belt 32 close to the side wall of the vertical section of the processing frame 1, and the push plates 321 are located between each adjacent group of stripping rods 34 and can move back and forth along the length direction of the stripping rod 34.

[0061] A plurality of linkage rods 322 corresponding to the push plates 321 are slidingly provided on the vertical section of the processing frame 1, and the end of the linkage rod 322 located inside the processing frame 1 is installed on the push plate 321, and the end of the linkage rod 322 located outside the processing frame 1 is jointly installed with a linkage plate 323, and a telescopic spring rod 324 for resetting the linkage plate 323 is jointly installed between the linkage plate 323 and the vertical section of the processing frame 1.

[0062] A linkage straight rod 325 is installed on the rotating shaft 11 on the side close to the rubber belt 32, and the linkage straight rod 325 is installed on the processing frame 1 through a bearing. A linkage connecting rod 326 is installed on the processing frame 1 through a bearing. A traction rope 327 is installed on the linkage connecting rod 326. The end of the traction rope 327 away from the linkage connecting rod 326 is installed on the linkage plate 323. An incomplete gear 328 is installed on the linkage straight rod 325, and a spur gear 329 meshing with the incomplete gear 328 is installed on the linkage connecting rod 326.

[0063] A cylindrical rod 1 which is level with the linkage rod 322 is installed on the vertical section of the processing frame 1 on which the linkage link 326 is installed, and a fixed pulley 13 is installed on the cylindrical rod 1. A cylindrical rod 2 is arranged between the cylindrical rod 1 and the linkage link 326, and the cylindrical rod 2 is installed on the vertical section of the processing frame 1, and a fixed pulley 2 14 is installed on the cylindrical rod 2. The end of the traction rope 327 away from the linkage plate 323 passes through the side of the fixed pulley 13 away from the processing frame 1 and the side of the fixed pulley 2 14 close to the processing frame 1 in sequence, and then is installed on the linkage link 326.

[0064] During specific operation, the corresponding rotating shaft 11 drives the linkage straight rod 325 to rotate during the rotation of the linkage straight rod 325, and the incomplete gear 328 and the spur gear 329 are engaged with each other during the rotation of the linkage straight rod 325, further driving the linkage connecting rod 326 to rotate. During the rotation of the linkage connecting rod 326, the traction rope 327 is wound around it. At this time, the traction rope 327 cooperates with the fixed pulley 13 and the fixed pulley 2 14 to drive the linkage plate 323 to move away from the processing frame 1. At this time, the telescopic spring rod 324 is stretched, and the linkage plate 323 drives the linkage rod 322 to move synchronously during the movement of the linkage plate 323, and the linkage rod 322 drives the pushing plate 321 to move during the movement of the linkage rod 322. At this time, the pushing plate 321 can push the straw fiber wrapped around the stripping rod 34 out of the stripping rod 34 and fall onto the feeding belt 12 during the movement.

[0065] When the teeth on the incomplete gear 328 are disengaged from the spur gear 329, the traction rope 327 is no longer subject to the restraint force of the linkage link 326, and the telescopic spring rod 324 is reset to drive the linkage plate 323 to reset. At this time, the linkage plate 323 drives the push rod to reset synchronously through the linkage rod 322, and the traction rope 327 is reset synchronously at this time. Repeating the above action can drive the push plate 321 to move back and forth periodically, thereby achieving the purpose of separating the straw fiber from the stripping rod 34.

[0066] It should be noted that the fixed pulley 13 and the fixed pulley 2 14 cooperate with each other to reverse the traction rope 327 to ensure that the traction rope 327 drives the linkage plate 323 to move toward the side away from the processing frame 1 during the rotation of the linkage link 326.

[0067] Example 2: Review Figure 2 On the basis of the first embodiment, a liquid inlet pipe 15 is installed through both vertical sections of the processing frame 1 , and a liquid spray pipe 16 is installed on the opposite surface of the liquid inlet pipe 15 .

[0068] The conveyor belt 24 rotates the stripped straw strips through friction, generating centrifugal force that spreads the straw strips outward, increasing the space between them and further exposing their internal structure. The liquid inlet pipe 15 and the liquid spray pipe 16 work together to precisely spray the microbial strains into the exposed interior of the straw strips during the spreading process, ensuring sufficient and effective contact between the microbial strains and the straw strips. This significantly increases the reaction rate and efficiency between the straw and the microbial strains, enabling rapid and sufficient biofertilizer production.

[0069] Finally, the straw sprayed with microorganisms is collected and processed.

[0070] Finally, refer to Figure 7 The present invention also provides a biofertilizer fermentation preparation process, the preparation process comprising the following steps:

[0071] S1: Feeding preparation, the conveyor roller 23 near the stripping rod 34 is driven to rotate by an external driving force, and the conveyor belt 24 is driven to move during the rotation of the conveyor roller 23. At this time, the straw is placed between the two conveyor belts 24 in turn. The moving conveyor belt 24 cooperates with the stationary conveyor belt 24 to drive the straw to move intermittently into the processing frame 1, that is, every time the straw moves a certain distance into the processing frame 1, the moving conveyor belt 24 stops for a while.

[0072] S2: Stripping treatment. During the period when the moving conveyor belt 24 stops, the rotating shaft 31 is driven to rotate by an external driving force. During the rotation of the rotating shaft 31, the rubber belt 32 is driven to move. During the movement of the rubber belt 32, the stripping rod 34 is driven to move along the depth direction of the processing frame 1. Then, the stripping rod 34 can strip the straw, so that the straw is stripped into a strip structure.

[0073] S3: Spraying treatment, spraying microbial strains on the stripped straw.

[0074] S4: Collection and processing: collecting and processing the straw sprayed with microbial strains.
