Description

Technical Field

[0001] This invention belongs to the field of bio-organic fertilizer fermentation technology, specifically a fermentation device for bio-organic fertilizer processing. Background Technology

[0002] Bio-organic fertilizer is an environmentally friendly organic fertilizer made from organic waste such as livestock and poultry manure, straw, mushroom residue, and kitchen waste through microbial fermentation and harmless treatment. Turning the compost pile is a crucial step in the production process. Turning and stirring the compost allows it to fully contact the air, replenishing oxygen, dissipating heat from the pile, and regulating temperature and humidity, thereby promoting microbial activity and accelerating the fermentation process.

[0003] Currently, in large-scale production, existing fermentation devices typically only perform simple top-to-bottom turning, swapping the positions of organic fertilizer at the bottom and surface of the fermentation pile. This simplistic turning method lacks specificity and cannot classify and precisely turn the organic fertilizer according to its nutrient state and actual fermentation stage. Organic fertilizers at different fermentation levels and requiring different fermentation conditions are easily turned to unsuitable positions. Specifically, because the device's operating path is fixed, organic fertilizers that were originally on the outer layer and had lower temperatures often return to the outer layer after turning, failing to change their fermentation environment. This leads to prolonged fermentation time, reduced efficiency, and uneven decomposition of the organic fertilizer. Some organic fertilizers are under-fermented, while others are over-fermented, ultimately affecting the quality of the bio-organic fertilizer product. Summary of the Invention

[0004] The purpose of this invention is to provide a fermentation device for processing bio-organic fertilizer, so as to solve the problems mentioned in the background art.

[0005] The technical solution of this invention is as follows: A fermentation device for processing bio-organic fertilizer includes a movable frame, on which a conveying mechanism and a driving mechanism are installed. The driving mechanism drives the conveying mechanism. A first screening plate is fixedly connected to the movable frame, and a receiving shell is fixedly connected to the movable frame. The receiving shell has first openings distributed symmetrically at the center. A second screening plate located below the receiving shell is fixedly connected to the movable frame. A crushing mechanism located below the second screening plate is installed on the movable frame. A dispersing plate is rotatably connected to the movable frame. The receiving shell has second openings located above the dispersing plate and distributed in an array. A pressing mechanism for discharging organic fertilizer from the receiving shell is provided. An auxiliary dispersing mechanism for dispersing the organic fertilizer on the dispersing plate is provided on the movable frame.

[0006] Furthermore, the first screening plate is located between the conveying mechanism and the receiving shell, and the receiving shell is located between the first screening plate and the dispersing plate.

[0007] Furthermore, the pressing mechanism includes: a drive motor mounted on the receiving shell, with the output shaft of the drive motor passing through the receiving shell; a pressing rod, comprising several rods arranged in an array, all fixed to the output shaft of the drive motor, the pressing rods being in contact with the side wall of the receiving shell; and an intercepting plate, the intercepting plates being centrally symmetrically distributed, all rotatably connected to the receiving shell, and used to seal the corresponding first opening, with a first elastic element provided between the intercepting plate and the receiving shell.

[0008] Furthermore, an array of fixed rods are fixedly connected inside the receiving shell, and the fixed rods are staggered with the extrusion rods.

[0009] Furthermore, the extrusion rod is at the same height as the corresponding second opening, and the thickness of the extrusion rod is not greater than the height of the second opening.

[0010] Furthermore, both the compression rod and the fixing rod are composed of two arc-shaped rods that are centrally symmetrically distributed.

[0011] Furthermore, an array of guide plates is fixed to the side of the receiving shell near the second opening, and the guide plates gradually tilt from top to bottom toward the side away from the receiving shell.

[0012] Furthermore, the auxiliary material distribution mechanism includes: a drive shaft rotatably connected to the movable frame; an extrusion member fixed to the drive shaft for extruding the dispersion plate; and a pressing plate slidably connected to the movable frame, with a second elastic member provided between the pressing plate and the movable frame, and the pressing plate being located above the dispersion plate.

[0013] Furthermore, it also includes a clearing mechanism, which is disposed on the first screening plate and is used to clear the screen holes on the first screening plate. The clearing mechanism includes symmetrically distributed mounting plates, which are fixedly connected to the first screening plate. The symmetrically distributed mounting plates are rotatably connected to an array of drive shafts. All the drive shafts are drively connected to the drive mechanism. The drive shafts are fixedly connected to uniformly distributed fixing blocks. Adjacent fixing blocks on the same drive shaft are staggered. The fixing blocks are slidably connected to sliding shells. The sliding shells are rotatably connected to intercepting bars. A third elastic element is disposed between the sliding shells and the intercepting bars. The sliding shells are fixedly connected to symmetrically distributed limiting posts. The first screening plate is located on the moving path of all the limiting posts.

[0014] Furthermore, the mounting plate is fixedly connected with an array of scrapers, each scraper corresponding to one of the drive shafts. The scrapers are used to limit the movement of the intercepting bars, and the fixing blocks are used to limit the movement of adjacent intercepting bars.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a first screening plate to initially screen organic fertilizer, allowing dry and dispersed organic fertilizer to fall preferentially into the composting pit. Then, based on the state of the organic fertilizer, a receiving shell is used to sort it, transferring the organic fertilizer that is difficult to cut to a crushing mechanism for crushing. This crushed portion of the organic fertilizer falls onto the dry and dispersed organic fertilizer. Simultaneously, the receiving shell transfers the remaining, shredable organic fertilizer to a dispersing plate, which then moves it to the top layer of organic fertilizer in the composting pit. This disperses the organic fertilizer to appropriate locations according to its different states, facilitating rapid fermentation, improving the quality of turning the compost, and increasing the fermentation efficiency of the organic fertilizer.

[0016] This invention uses a relatively rotating extrusion rod and a fixed rod to shear and crush the organic fertilizer inside the receiving shell, thereby processing agglomerated or hard organic fertilizer and reducing the particle size of this part of the organic fertilizer for subsequent fermentation.

[0017] This invention uses the rotation of the intercepting strip to move the fibrous material remaining on the first screening plate, reducing the obstruction of the passageway by the fibrous material on the first screening plate, so that the first screening plate can screen the organic fertilizer, improve the quality of turning, and thus improve the fermentation effect.

[0020] The technical solution will be further explained below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to the components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning.

[0021] Example 1 like Figures 1-7 As shown, a fermentation device for processing bio-organic fertilizer includes a movable frame 1, on which a conveying mechanism 2 and a driving mechanism 3 are installed. The driving mechanism 3 drives the conveying mechanism 2 to work. A first screening plate 4 is fixedly connected to the movable frame 1, and a receiving shell 5 is fixedly connected to the movable frame 1. The receiving shell 5 is provided with centrally symmetrically distributed first openings 501. A second screening plate 6 located below the receiving shell 5 is fixedly connected to the movable frame 1. A crushing mechanism 7 located below the second screening plate 6 is installed on the movable frame 1. A dispersing plate 41 is rotatably connected to the movable frame 1. The receiving shell 5 is provided with second openings 502 located above the dispersing plate 41 and arranged in an array. A pressing mechanism for discharging the organic fertilizer inside the receiving shell 5 is provided. An auxiliary dispersing mechanism for dispersing the organic fertilizer on the dispersing plate 41 is provided on the movable frame 1. The first screening plate 4 is located between the conveying mechanism 2 and the receiving shell 5, and the receiving shell 5 is located between the first screening plate 4 and the dispersing plate 41.

[0022] The above scheme can change the stacking position between different layers of organic fertilizer; the mobile frame 1 is placed on the existing composting pit and has its own active moving structure. The active moving structure is an electric drive structure in the prior art. Four electric wheels can be installed on the lower side of the mobile frame 1, and a guide rail is set on the upper side of the composting pit to guide the electric wheels (this specific structure is consistent with the electric drive structure of the turning structure in the existing fermentation device). The conveying mechanism 2 is an existing belt conveyor. A guide plate 32 with an inclined surface is installed on the lower side of the conveying mechanism 2, which is in contact with the bottom surface of the composting pit. The first screening plate 4 has an array of channels for screening dry and dispersed organic fertilizer. The left side of the first screening plate 4 is higher than its right side. The receiving shell 5 is located to the right of the first screening plate 4. A portion of the organic fertilizer that has clumped or hardened due to excessive moisture on the receiving shell 5 falls onto the second screening plate 6 through the first opening 501. The first opening 501 has two symmetrically distributed openings, and the second opening 502 has two arranged in an array. The crushing mechanism 7 is an existing roller crushing device used to crush the organic fertilizer on the second screening plate 6. The remaining clumps or hardened organic fertilizer on the receiving shell 5 fall onto the dispersing plate 41 through the second opening 502. The dispersing plate 41 is located to the right of the receiving shell 5, and its left side is higher than its right side.

[0023] like Figures 2-5 As shown, the pressing mechanism includes: a drive motor 21, which is mounted on the receiving shell 5 and has its output shaft passing through the receiving shell 5; a pressing rod 22, which has several rods arranged in an array and fixed to the output shaft of the drive motor 21, with the pressing rods 22 in contact with the side wall of the receiving shell 5; and an intercepting plate 23, which is centrally symmetrically distributed and rotatably connected to the receiving shell 5, and used to block the corresponding first opening 501. A first elastic element is provided between the intercepting plate 23 and the receiving shell 5. The pressing rods 22 and the corresponding second opening 502 are at the same height, and the thickness of the pressing rods 22 is not greater than the height of the second opening 502.

[0024] In the above scheme, the drive motor 21 is located on the lower side of the receiving shell 5, and a protective shell is provided on its outer side to prevent organic fertilizer from entering the interior of the drive motor 21; there are two extrusion rods 22 distributed vertically, which extrude the clumped organic fertilizer during the rotation of the extrusion rods 22 and drive it to move to the corresponding first opening 501 and second opening 502, so that the organic fertilizer on the receiving shell 5 falls onto the second screening plate 6 and the dispersing plate 41 respectively; the first elastic element on the intercepting plate 23 is a torsion spring, which is used to drive the corresponding intercepting plate 23 to reset.

[0025] like Figures 2-5As shown, two fixed rods 31 are fixedly connected in an upper and lower array inside the receiving shell 5, and the fixed rods 31 and the extrusion rod 22 are staggered. During the rotation of the extrusion rod 22, the extrusion rod 22 and the fixed rod 31 together shear and crush the organic fertilizer in the receiving shell 5, so as to disperse the clump of organic fertilizer. The clump of organic fertilizer that has been crushed in the receiving shell 5 is discharged from the second opening 502, while the clump of organic fertilizer that cannot be crushed is discharged from the first opening 501 by the pushing of the extrusion rod 22 and the limiting guidance of the fixed rod 31. The extrusion rod 22 and the fixed rod 31 are both composed of two arc-shaped rods that are centrally symmetrically distributed. The arc structure guides the organic fertilizer, making it easier for the extrusion rod 22 to drive the organic fertilizer to move.

[0026] like Figures 2-5 As shown, two guide plates 32 are fixedly connected to the right side of the receiving shell 5 in an array. The guide plates 32 gradually tilt from top to bottom away from the receiving shell 5. The guide plates 32 are used to guide the organic fertilizer discharged from the corresponding second opening 502 to reduce organic fertilizer splashing.

[0027] like Figure 2 , Figure 6 and Figure 7 As shown, the auxiliary bulking mechanism includes: a drive shaft 42, which is rotatably connected to the movable frame 1 and is drive-connected to the drive shaft of the electric wheel in the active moving structure on the movable frame 1; an extrusion member 43, which is composed of a circular plate and circumferentially distributed protrusions, and is fixedly connected to the drive shaft 42. The protrusions of the extrusion member 43 are used to extrude the dispersing plate 41, causing the dispersing plate 41 to vibrate up and down, which facilitates the loosening of the organic fertilizer on the dispersing plate 41; and a pressing plate 44, which is slidably connected to the movable frame 1, and a second elastic element, which is a spring, is provided between the pressing plate 44 and the movable frame 1. The pressing plate 44 is located above the dispersing plate 41 and is used to press the blocky organic fertilizer on the dispersing plate 41, change the state of the blocky organic fertilizer, and improve the fermentation efficiency of the organic fertilizer.

[0028] The working principle of this embodiment: When it is necessary to turn the organic fertilizer in the composting pit, move the mobile frame 1 to the right side of the composting pit, start the drive mechanism 3, crushing mechanism 7 and drive motor 21. The drive mechanism 3 drives the conveying mechanism 2 to move, and at the same time the output shaft of the drive motor 21 drives all the extrusion rods 22 to rotate. Then start the mobile frame 1 and make it move slowly to the left. During the movement, the guide plate 32 on the lower side of the conveying mechanism 2 guides the organic fertilizer and moves the organic fertilizer onto the conveying mechanism 2. Then the conveying mechanism 2 transports the organic fertilizer upward to the first screening plate 4. The first screening plate 4 screens the organic fertilizer on it. The dry and dispersed organic fertilizer falls back into the composting pit through the through groove of the first screening plate 4. Under normal circumstances, the dry and dispersed organic fertilizer is located on the upper side of the organic fertilizer in the composting pit. The fermentation state of this part of the organic fertilizer is better than that of the organic fertilizer on the lower side.

[0029] During the screening process of organic fertilizer on the first screening plate 4, organic fertilizer with a particle size larger than the through groove on the first screening plate 4 will move to the right under the guidance of the first screening plate 4 and fall into the receiving shell 5. Most of the organic fertilizer in the receiving shell 5 is organic fertilizer that has clumped due to excessive moisture, and a small part is residual dry and dispersed organic fertilizer. The rotating extrusion rod 22 extrudes most of the organic fertilizer and drives the organic fertilizer to move. When the extrusion rod 22 passes the fixed rod 31, the two together shear some of the clumped organic fertilizer, so that the clumped organic fertilizer can be dispersed, so that the moisture in the clumped organic fertilizer can be discharged and contact with the outside air. During this process, the extrusion rod 22 pushes the crushed organic fertilizer to the second opening 502 of the receiving shell 5. Then, under the extrusion action of the extrusion rod 22, this part of the organic fertilizer falls through the second opening 502 onto the right-side dispersion plate 41.

[0030] For the tough and difficult-to-shred organic fertilizer inside the receiving shell 5, during the rotation of the extrusion rod 22, the extrusion rod 22 pushes this part of the organic fertilizer to move. When this part of the organic fertilizer comes into contact with the fixing rod 31, the fixing rod 31 limits this part of the organic fertilizer, preventing it from continuing to rotate circumferentially. As the extrusion rod 22 pushes, this part of the organic fertilizer gradually moves outward under the combined guiding action of the extrusion rod 22 and the fixing rod 31, until it moves to the first opening 501 on the receiving shell 5. When this part of the organic fertilizer is aligned with the first opening 501 on the receiving shell 5, under the pushing action of the extrusion rod 22, this part... The organic fertilizer is squeezed against the adjacent interceptor plate 23, causing the interceptor plate 23 to deflect. The first elastic element stores force and releases the obstruction of the corresponding first opening 501, so that the organic fertilizer falls through the first opening 501 onto the second screening plate 6. Some of the dry and dispersed organic fertilizer will preferentially pass through the second screening plate 6 and fall into the composting tank. The remaining organic fertilizer will move along the second screening plate 6 and enter the crushing mechanism 7. The crushing mechanism 7 crushes the organic fertilizer that enters it, reducing the particle size of the organic fertilizer so that the organic fertilizer can come into contact with the outside air, thereby improving the fermentation efficiency of the organic fertilizer.

[0031] Once the interceptor plate 23 is no longer compressed by the organic fertilizer, it resets under the action of the first elastic element and seals the corresponding first opening 501 again.

[0032] During the process of the first screening plate 4 and the crushing mechanism 7 processing the organic fertilizer, since the first screening plate 4 is located on the left side of the crushing mechanism 7, the organic fertilizer at the first screening plate 4 will fall into the composting pit before the organic fertilizer at the crushing mechanism 7. That is, the dry and dispersed organic fertilizer will fall into the composting pit first and be located at the bottom of the organic fertilizer. The crushed clumps of organic fertilizer will cover the dry and dispersed organic fertilizer and be located in the middle of the whole organic fertilizer.

[0033] During the movement of the mobile frame 1, the electric wheel of the active moving structure on the mobile frame 1 drives the transmission shaft 42 to rotate. The transmission shaft 42 drives the extruder 43 to rotate. The extruder 43 drives the convex column on it to rotate and extrudes the dispersing plate 41, causing the dispersing plate 41 to vibrate up and down. After the organic fertilizer that has been shredded in the receiving shell 5 falls onto the dispersing plate 41, the dispersing plate 41 guides the organic fertilizer on it to move to the right and shakes the organic fertilizer on it, so that this part of the organic fertilizer is dispersed and falls into the composting pit. Since the dispersing plate 41 is located on the right side of the crushing mechanism 7, the organic fertilizer at the crushing mechanism 7 falls into the composting pit before the organic fertilizer at the dispersing plate 41. That is, the organic fertilizer falling from the dispersing plate 41 is located on the top layer of organic fertilizer. By dispersing and layering organic fertilizers in different fermentation states, the position of the organic fertilizer is changed, so that organic fertilizers in different states are in suitable positions, which helps the fermentation of organic fertilizer and improves the overall fermentation efficiency.

[0034] During the vibration of the dispersing plate 41, the organic fertilizer gradually moves to the right. When the dispersing plate 41 swings upward, it drives the organic fertilizer on it to move upward synchronously, causing the pressing plate 44 to press the organic fertilizer. The pressing plate 44 compresses the second elastic element, thereby dispersing the lumpy organic fertilizer on the dispersing plate 41 and changing the state of the organic fertilizer clumping on the dispersing plate 41 so that it can come into contact with the outside air and improve the fermentation efficiency of the organic fertilizer. When the protrusion of the extruder 43 no longer presses the dispersing plate 41, the dispersing plate 41 swings downward under the action of gravity and comes into contact with the circular plate of the extruder 43. The pressing plate 44 moves downward under the action of the second elastic element.

[0035] When the mobile frame 1 moves to the left side of the composting pit, the turning operation of the organic fertilizer is completed. Then, turn off the drive mechanism 3, the crushing mechanism 7 and the drive motor 21. If the turning operation needs to be performed again, move the mobile frame 1 to the right side of the composting pit and repeat the above process.

[0036] Example 2 Because some bio-organic fertilizers contain fibrous materials, these fibrous materials may not be able to be fermented and decomposed. As a result, during the turning process, the fibrous materials will become entangled or piled on the screening plate, causing blockage of the screening plate mesh. This will affect the screening effect of different layers of organic fertilizer and reduce the fermentation efficiency.

[0037] Based on Example 1, such as Figures 8-11 As shown, it also includes a clearing mechanism, which is disposed on the first screening plate 4 and is used to clear the screen holes on the first screening plate 4. The clearing mechanism includes two mounting plates 51 symmetrically distributed front and rear, which are respectively fixed to the front and rear sides of the first screening plate 4. The two mounting plates 51 are rotatably connected to a plurality of arrayed drive shafts 52. All drive shafts 52 are connected to the drive mechanism 3. In this embodiment, the drive mechanism 3 is connected to all drive shafts 52 through a gear set and a pulley belt set. Evenly distributed fixing blocks 53 are fixed on the drive shafts 52. The fixing blocks 53 are aligned with the corresponding through slots on the first screening plate 4. Adjacent fixing blocks 53 on the same drive shaft 52 are staggered vertically. The fixing blocks 53 are slidably connected to a sliding shell 54. A rotatable intercepting bar 55 is connected, and a third elastic element is provided between the sliding shell 54 and the intercepting bar 55. In this paper, the material of the sliding shell 54 and the intercepting bar 55 can be the same as that of the existing counterweight. A spring can be provided between the sliding shell 54 and the fixed block 53. The material limitation and spring limitation here are used to ensure that the sliding shell 54 slides smoothly along the fixed block 53, so that the protrusion of the fixed block 53 loses connection with the groove of the intercepting bar 55. The intercepting bar 55 is used to clean the fibers accumulated in the corresponding through groove on the first screening plate 4. The third elastic element is a torsion spring. The sliding shell 54 is fixed with symmetrically distributed limiting posts 56, and the first screening plate 4 is located on the moving path of all the limiting posts 56. When the drive shaft 52 drives the fixed block 53 on it to rotate to the upper side, the first screening plate 4 contacts the corresponding limiting post 56.

[0038] like Figures 8-10 As shown, the mounting plate 51 is fixedly connected with an array of scraper blades 61, which correspond one-to-one with the drive shaft 52. The scraper blades 61 are used to limit the interception strips 55. The fixing block 53 is provided with a protrusion, and the interception strips 55 are provided with a groove. The protrusion of the fixing block 53 is used to limit the adjacent interception strips 55. When the protrusion of the fixing block 53 is inserted into the groove of the interception strip 55, the interception strip 55 cannot rotate, and at this time the interception strip 55 is located above the fixing block 53.

[0039] The working principle of this embodiment: During the operation of the drive mechanism 3, the drive mechanism 3 drives all the drive shafts 52 to rotate counterclockwise (with) through the gear set and pulley belt set. Figure 1(Based on the front view perspective), the drive shaft 52 drives all the fixed blocks 53 on it to rotate, and the fixed blocks 53 drive the adjacent sliding shells 54 to rotate, so as to... Figure 10 Taking the part on the right as an example, the sliding shell 54 drives the intercepting strip 55 to rotate synchronously, and the scraper 61 intercepts the intercepting strip 55, causing the intercepting strip 55 to rotate relative to the sliding shell 54. The third elastic element begins to store force, and the groove of the intercepting strip 55 is misaligned with the protrusion of the fixed block 53. During this process, the scraper 61 moves relative to the intercepting strip 55, and at the same time, the scraper 61 cleans the fibers on the intercepting strip 55.

[0040] After passing the scraper 61, the intercepting strip 55 swings back to its original position under the action of the third elastic element, that is, the groove of the intercepting strip 55 aligns with the protrusion of the fixing block 53. As the fixing block 53 rotates, it drives the sliding shell 54 to rotate synchronously. The sliding shell 54 drives the limiting post 56 on it to rotate until the limiting post 56 contacts the first screening plate 4. The first screening plate 4 then squeezes the limiting post 56, preventing it from moving upward. The limiting post 56 drives the sliding shell 54 to move downward relative to the fixing block 53, so that the protrusion of the fixing block 53 enters the groove of the corresponding intercepting strip 55. The moving shell 54 cannot rotate relative to the moving shell. As the intercepting bar 55 rotates, the intercepting bar 55 moves the fiber material remaining on the corresponding through groove on the first screening plate 4 and drives the fiber material to move. The fiber material passes through the corresponding through groove and moves to the lower side of the first screening plate 4 until the fixed block 53 rotates to tilt downward. Under the action of gravity, the intercepting bar 55 and the sliding shell 54 slide downward, causing the protrusion of the fixed block 53 to move out of the groove of the intercepting bar 55. At this time, the intercepting bar 55 and the sliding shell 54 can rotate relative to each other until the intercepting bar 55 contacts the scraper 61. The above operation is repeated so that the scraper 61 cleans the corresponding intercepting bar 55.

[0041] The present invention has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
