Description

Technical Field

[0001] This invention relates to the field of organic fertilizer production technology, and in particular to a turning device for organic fertilizer fermentation. Background Technology

[0002] In the process of organic fertilizer preparation, raw materials such as animal manure (e.g., chicken manure, cow manure), straw, and fermentation agents are mixed using mixing equipment and then composted. The fermentation cycle is usually quite long, and during the composting process, it is necessary to monitor the changes in the carbon-to-nitrogen ratio (C / N), temperature, and moisture content of the fermented material in real time.

[0003] When tests reveal an imbalance in the carbon-nitrogen ratio or insufficient moisture in the fermentation material, it is necessary to replenish dry materials, microbial agents, or conditioners promptly. Currently, the industry commonly uses manual hand-spreading for replenishment. However, due to the large volume of organic fertilizer piles, manual spreading is labor-intensive and prone to uneven replenishment. Summary of the Invention

[0004] The purpose of this invention is to provide a turning device for organic fertilizer fermentation, which has the effect of improving the uniformity of organic fertilizer feeding.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a fermentation tank, a movable support horizontally mounted on the fermentation tank, and a material turning mechanism mounted on the movable support. A material spreading mechanism is horizontally mounted on the top of the movable support. The material spreading mechanism includes a material spreading cylinder horizontally mounted on the movable support and a material spreading shaft rotatably mounted inside the material spreading cylinder. Spiral material spreading blades are mounted on the material spreading shaft. A feed hopper is connected to the top of the material spreading cylinder. An elongated discharge port is opened at the bottom of the material spreading cylinder in a direction parallel to the central axis of the material spreading shaft. A drive motor for driving the material spreading shaft to rotate is mounted on the movable support. A material spreading auxiliary mechanism for expanding the spreading area is mounted on the movable support, and the material spreading auxiliary mechanism is located directly below the discharge port.

[0006] By adopting the above technical solution, during the organic fertilizer composting fermentation process, when an imbalance in the carbon-nitrogen ratio of the fermenting material in the fermentation tank is detected and process replenishment is required, the material to be replenished (such as straw powder, dry manure, etc.) is put into the feed hopper of the spreading mechanism; the drive motor is started, and the drive motor drives the spreading shaft in the spreading cylinder to rotate at a constant speed. The spiral spreading blades on the spreading shaft rotate synchronously with the spreading shaft, pushing the material in the feed hopper evenly along the length of the spreading cylinder. During the pushing process, the material flows out at a constant speed from the long strip-shaped discharge port at the bottom of the spreading cylinder under the squeezing action of the spiral blades; since the spreading auxiliary mechanism is located directly below the discharge port, the flowing material falls directly into the spreading auxiliary mechanism, which expands the spreading coverage area; at the same time, the moving support moves slowly along the horizontal direction of the fermentation tank, driving the spreading mechanism, spreading auxiliary mechanism and turning mechanism to move synchronously, realizing full-area and continuous replenishment of the fermenting material in the fermentation tank; at the same time as replenishment, the turning mechanism also turns the material in the fermentation tank, mixing the newly added material with the fermentation tank. The existing fermentation material is turned and mixed to ensure full contact between the supplementary material and the original material, guaranteeing uniform fermentation. The spiral-shaped spreading blades push the material at a constant speed, ensuring a continuous and uniform flow from the long, narrow discharge port, preventing localized accumulation or interruptions. Combined with the horizontal movement of the moving support, this achieves uniform coverage of the supplementary material along the length of the fermentation tank. The spreading auxiliary mechanism further expands the spreading area, solving the problems of "localized accumulation and omissions" inherent in traditional manual spreading, significantly improving the uniformity of the process and ensuring consistent carbon-nitrogen ratios and material composition in all areas of the fermentation tank, thus guaranteeing the organic fertilizer's composting effect. By integrating the spreading mechanism onto the moving support and linking it with the turning mechanism, the material is turned and mixed simultaneously with the supplementary material, eliminating the need for additional supplementary equipment and processes, simplifying the organic fertilizer production process, and improving the synergistic efficiency of supplementation and turning. The long, narrow discharge port is parallel to the central axis of the spreading shaft, ensuring that the material flow direction matches the moving direction of the moving support, further improving the uniformity of the supplementary material and preventing uneven supplementation caused by material deviation.

[0007] A further configuration of the present invention is as follows: the material spreading auxiliary mechanism includes an auxiliary shaft rotatably mounted on the movable support in a direction parallel to the central axis of the material spreading shaft, and a plurality of auxiliary blades uniformly arranged on the auxiliary shaft in a direction parallel to the central axis of the auxiliary shaft, wherein an open material spreading cavity is formed between two adjacent auxiliary blades, a first gear is provided at the end of the auxiliary shaft, and a second gear meshing with the first gear is provided at the end of the material spreading shaft, wherein the gear ratio of the first gear and the second gear is 1:2.

[0008] By adopting the above technical solution, when the spreading shaft rotates, the second gear at its end rotates synchronously. Since the second gear meshes with the first gear at the end of the auxiliary shaft (gear ratio 1:2), the second gear drives the first gear to rotate at a uniform speed, thereby driving the auxiliary shaft to rotate along its own central axis. Several auxiliary blades evenly arranged on the auxiliary shaft rotate synchronously with the auxiliary shaft. The open spreading chamber formed between adjacent auxiliary blades moves cyclically to directly below the discharge port as the auxiliary shaft rotates. After the material flowing out of the discharge port falls into the spreading chamber, the auxiliary blades continue to rotate, using centrifugal force to evenly distribute the material in the spreading chamber to both sides, expanding the spreading coverage width. Simultaneously, since the gear ratio of the first gear to the second gear is 1:2, the speed of the spreading shaft is twice the speed of the auxiliary shaft, ensuring that the speed at which the spreading shaft pushes the material matches the speed at which the auxiliary shaft throws the material, avoiding material accumulation in the spreading chamber or uneven feeding caused by excessively fast throwing. The open spreading chamber enables... The quantitative material receiving avoids localized concentration caused by direct material falling. Combined with the rotating and scattering of auxiliary blades, the linear flow of material from the discharge port is transformed into a uniform lateral diffusion, significantly expanding the coverage area and ensuring even distribution of feed across the width of the fermentation tank. A 1:2 gear ratio enables coordinated rotation between the spreading shaft and the auxiliary shaft, ensuring precise matching of material delivery and scattering. This avoids both excessive localized feeding due to material accumulation and insufficient feeding due to excessively rapid scattering, further improving the uniformity of process feeding. The gear meshing linkage between the spreading auxiliary mechanism and the spreading shaft eliminates the need for additional drive equipment, simplifying the equipment structure and reducing energy consumption. The evenly distributed auxiliary blades ensure consistent material delivery to each spreading chamber, resulting in uniform scattering force and preventing localized dense or sparse scattering. The open-type spreading chambers facilitate material entry and exit, reducing material adhesion and further guaranteeing feeding uniformity.

[0009] A further configuration of the present invention is as follows: the material turning mechanism includes a rotating shaft rotatably mounted on the movable support in a direction parallel to the central axis of the spreading shaft, and a plurality of first material turning blocks uniformly arranged on the rotating shaft; a first synchronous wheel is provided at the end of the material turning shaft, a second synchronous wheel is provided at the end of the auxiliary shaft, and a synchronous belt is provided between the first synchronous wheel and the second synchronous wheel.

[0010] By adopting the above technical solution, when the auxiliary shaft rotates, the second synchronous wheel at its end rotates synchronously, driving the first synchronous wheel at the end of the rotating shaft to rotate via a synchronous belt, thereby driving the rotating shaft to rotate at a constant speed along its own central axis; several first turning blocks evenly arranged on the rotating shaft rotate synchronously with the rotating shaft, turning and stirring the fermented material in the fermentation tank; after the feeding auxiliary mechanism evenly spreads the material on the surface of the fermented material, the first turning blocks fully turn and mix the surface material with the original fermented material at the bottom, so that the material is evenly distributed throughout the fermentation pile, avoiding the material remaining only on the surface and not participating in fermentation; at the same time, the feeding mechanism, the feeding auxiliary mechanism, and the turning mechanism are linked by gears and synchronous belts to achieve synchronous "feeding-turning", ensuring that the material is mixed immediately after feeding; through the synchronous belt The system is interconnected, enabling coordinated operation of material spreading and turning. After material replenishment, turning and mixing can be performed immediately, preventing the replenished material from accumulating on the surface of the fermenting material and ensuring that the replenished material is evenly distributed throughout the fermentation pile. This ensures that every part of the fermenting material in the fermentation tank can fully contact the replenished material, effectively solving the problem of "rich surface and scarce bottom layer" of the replenished material. This further improves the uniformity of process replenishment and ensures stable fermentation parameters. The evenly distributed first turning block ensures that the turning range covers the entire cross-section of the fermentation tank, avoiding turning dead corners and further improving the mixing uniformity of the replenished material with the original material. No additional turning drive equipment is required. The turning mechanism is linked by the driving force of the spreading shaft, simplifying the equipment structure, reducing equipment manufacturing costs and maintenance difficulty, while improving the coordination efficiency of replenishment and turning, and shortening the production cycle.

[0011] A further feature of the present invention is that the radius of the first synchronous pulley is smaller than the radius of the second synchronous pulley, and the transmission ratio between the first synchronous pulley and the second synchronous pulley is 1:3.

[0012] By adopting the above technical solution, the radius of the first synchronous wheel is smaller than that of the second synchronous wheel, and the transmission ratio is 1:3. When the second synchronous wheel rotates once, the first synchronous wheel rotates three times, that is, the auxiliary shaft rotates once and the rotating shaft rotates three times. The auxiliary shaft drives the material spreading auxiliary mechanism to slowly spread the material (ensuring uniform spreading), and the rotating shaft drives the first turning block to quickly turn the fermented material, so that the material spread by the material spreading auxiliary mechanism can be quickly and evenly turned into the fermentation pile, avoiding local accumulation caused by the material staying on the surface for too long. At the same time, the reasonable setting of the speed difference... The system ensures that the turning and spreading speeds are matched, preventing material splashing due to excessive turning and spreading, and preventing material accumulation due to excessive turning and spreading. A 1:3 transmission ratio achieves coordinated rotation speeds for spreading and mixing. Slow spreading ensures that the material is evenly distributed across the width of the fermentation tank, while rapid turning ensures that the supplementary material is fully mixed with the existing fermented material, preventing localized enrichment of the supplementary material and ensuring that the supplementary material is evenly distributed throughout the fermentation pile. This significantly improves the uniformity and effectiveness of the process-based supplementation, ensures a consistent carbon-nitrogen ratio in all areas of the fermentation tank, and improves the quality of the finished organic fertilizer.

[0013] A further feature of the present invention is that: first traveling wheels are symmetrically arranged at both ends of the auxiliary shaft, and elongated moving grooves are symmetrically opened at the top of the movable bracket, with the bottom of the first traveling wheels engaging with the moving grooves.

[0014] By adopting the above technical solution, when the spreading shaft rotates, it drives the auxiliary shaft to rotate synchronously. Simultaneously, the first traveling wheels at both ends of the auxiliary shaft rotate synchronously. Since the first traveling wheels are engaged in the elongated moving groove at the top of the moving support, the rotating first traveling wheels and the moving groove form a rolling fit, thereby driving the moving support to move smoothly along the moving groove, that is, along the horizontal direction of the fermentation tank. During the movement of the moving support, the first traveling wheels always roll along the moving groove, providing stable support and guidance for the auxiliary shaft, ensuring that the auxiliary shaft always rotates synchronously in a direction parallel to the spreading shaft, avoiding misalignment between the spreading chamber and the discharge port caused by auxiliary shaft deviation. At the same time, the engagement of the first traveling wheels in the moving groove effectively limits the vertical floating of the auxiliary shaft, ensuring that the height and angle of material sprayed by the auxiliary blades remain stable, avoiding material spray deviation and uneven feeding caused by auxiliary shaft swaying and moving support deviation, thus achieving synchronous coordination between spreading and moving support movement. To ensure uniform material distribution across the entire area, the auxiliary shaft drives the first traveling wheel to rotate, which in turn drives the moving support to move smoothly along the moving trough. This achieves synchronous linkage between material distribution and movement, preventing uneven distribution caused by the discontinuity between the moving support's speed and the material distribution speed. The auxiliary shaft, in conjunction with the first traveling wheel, drives the moving support, eliminating the need for an additional drive unit for the moving support, simplifying the overall structure of the equipment, and reducing energy consumption and manufacturing costs. The rolling contact between the first traveling wheel and the moving trough not only reduces friction during the rotation of the auxiliary shaft, ensuring smooth operation of the auxiliary shaft and moving support, but also effectively prevents axial deviation of the auxiliary shaft, extending the equipment's service life. Simultaneously, the linkage structure of "auxiliary shaft-first traveling wheel-moving support" ensures that the relative position of the material distribution auxiliary mechanism and the material distribution mechanism remains stable, guaranteeing the continuity of the material distribution process, further improving the uniformity of material distribution, and preventing distribution interruptions or deviations due to equipment linkage failures.

[0015] A further configuration of the present invention is as follows: a first support block is symmetrically arranged on one side of the movable support, and a second support block is symmetrically arranged on the other side of the movable support; a second traveling wheel that cooperates with the movable groove is rotatably arranged at the bottom end of the first support block; a third traveling wheel that cooperates with the movable groove is rotatably arranged at the bottom end of the second support block; and the first traveling wheel is located between the second traveling wheel and the third traveling wheel.

[0016] By adopting the above technical solution, when the mobile support moves horizontally along the fermentation tank, the second traveling wheel at the bottom of the first support block on one side and the third traveling wheel at the bottom of the second support block on the other side roll synchronously along the moving groove, cooperating with the first traveling wheels at both ends of the auxiliary shaft to jointly support the mobile support and the auxiliary shaft. Since the first traveling wheel is located between the second and third traveling wheels, the three form a triangular support structure, ensuring that the mobile support remains horizontal and stable during the movement, avoiding the displacement of the feeding mechanism and feeding auxiliary mechanism caused by the tilting of the mobile support. At the same time, the cooperation between the second and third traveling wheels and the moving groove further improves the stability of the mobile support's movement, ensuring that the feeding mechanism moves at a uniform speed along the length of the fermentation tank, achieving uniform feeding; the second traveling wheel, The triangular distribution of the third and first traveling wheels ensures that the mobile support does not tilt or sway during movement, keeping the material spreading mechanism and auxiliary spreading mechanism horizontal at all times. This ensures uniform material flow from the discharge port and a stable throwing angle by the auxiliary spreading mechanism. Simultaneously, the uniform speed of the mobile support prevents uneven feeding along the length of the fermentation tank due to speed fluctuations, further improving the overall uniformity of process feeding. The coordinated support of multiple traveling wheels distributes the stress on the equipment, reduces wear on individual traveling wheels, and extends the equipment's service life. The precise matching of the traveling wheels and the moving trough ensures smooth movement of the mobile support, preventing jamming and guaranteeing the continuity of the feeding process. It also reduces vibration during equipment operation, preventing material spreading deviation caused by vibration, further ensuring uniform feeding.

[0017] A further provision of the present invention is that a reinforcing plate is fixedly disposed between the first support block, the movable bracket and the second support block, and a support structure with a triangular longitudinal section is formed between the first support block, the second support block and the reinforcing plate.

[0018] By adopting the above technical solutions, the triangular support structure effectively disperses the impact force and load generated during the operation of the mobile support, the spreading mechanism, and the turning mechanism, preventing deformation or breakage of the first and second support blocks and ensuring that the mobile support maintains a stable structural shape. Simultaneously, the triangular support structure enhances the overall rigidity of the mobile support, preventing bending during long-term operation and ensuring the relative stability of the spreading mechanism, spreading auxiliary mechanism, and turning mechanism, guaranteeing smooth material replenishment and turning processes. The reinforcing plates improve the overall strength and service life of the mobile support, reducing equipment maintenance frequency. The triangular support structure disperses the operating load, reducing wear on the wheels and support blocks, ensuring long-term stable operation of the equipment, further guaranteeing the stability of material replenishment uniformity, and preventing material replenishment interruptions due to equipment failure, thus improving organic fertilizer production efficiency.

[0019] A further provision of the present invention is that a second turning block is provided at the end of the first turning block away from the rotating shaft, and the cross-sectional area of ​​the second turning block is greater than the cross-sectional area of ​​the first turning block.

[0020] By adopting the above technical solution, since the cross-sectional area of ​​the second turning block is larger than that of the first turning block, the second turning block can drive more fermented material and supplementary material to turn over during the turning process, thus expanding the turning range. At the same time, the contact area between the second turning block and the fermented material is larger, and the turning force is more uniform. This allows the supplementary material sprinkled on the surface of the fermented material by the spreading auxiliary mechanism to be quickly and evenly turned into the bottom layer, fully mixed with the original fermented material, avoiding the accumulation of supplementary material on the surface, and ensuring that the supplementary material is evenly distributed throughout the entire fermentation pile.

[0021] A further configuration of the present invention is as follows: baffle frames are symmetrically arranged at both ends of the movable support, and the first synchronous wheel, the second synchronous wheel, the first gear and the second gear are all located in adjacent baffle frames between the inner wall of the fermentation tank and the spreading cylinder.

[0022] By adopting the above technical solution, the baffle frames at both ends of the movable support seal the first synchronous wheel, the second synchronous wheel, the first gear, and the second gear inside. When the spreading mechanism, the spreading auxiliary mechanism, and the turning mechanism are running, the fermented material, dust, and supplementary material in the fermentation tank are blocked by the baffle frames and cannot enter the gaps of the synchronous wheel, gear, and other transmission components. At the same time, the baffle frames are located between the inner wall of the fermentation tank and the spreading cylinder, which can prevent material from splashing onto the transmission components, ensuring smooth synchronous belt drive and gear meshing, avoiding jamming and wear of transmission components, ensuring stable rotation speed of the spreading shaft, auxiliary shaft, and rotating shaft, and ensuring the uniformity of the feeding and turning process.

[0023] A further configuration of the present invention is as follows: baffles are symmetrically arranged on both sides of the movable support in a downward direction, the auxiliary blade is located between the two baffles, and the baffles are located above the material turning mechanism.

[0024] By adopting the above technical solution, when the auxiliary blades of the material spreading auxiliary mechanism rotate and spread the material, the baffles set on both sides of the movable support in a downward direction wrap the auxiliary blades between the two baffles. When the material is spread by the auxiliary blades, the baffles can prevent the material from splashing excessively to both sides, and at the same time guide the material to be spread onto the surface of the fermented material in the fermentation tank, avoiding the material from splashing to the outside of the fermentation tank or other parts of the equipment. At the same time, the baffles are located above the turning mechanism, which can prevent the fermented material and the supplementary material from splashing upward during the turning process, preventing the material from sticking to the spreading mechanism and transmission components, ensuring the normal operation of the spreading mechanism, and ensuring the uniformity of the supplementary material.

[0025] The beneficial effects of this invention are:

[0026] 1. The spiral-shaped spreading blades push the material at a uniform speed, ensuring a continuous and uniform flow from the long, narrow discharge port. This prevents localized accumulation or interruptions in the material flow. Combined with the horizontal movement of the moving support, this achieves uniform coverage of the material along the length of the fermentation tank. The spreading auxiliary mechanism further expands the spreading area, solving the problems of "localized accumulation and missed areas" inherent in traditional manual spreading. This significantly improves the uniformity of the process-based feeding, ensuring consistent carbon-nitrogen ratios and material composition across all areas of the fermentation tank, thus guaranteeing the organic fertilizer's composting effect. By integrating the spreading mechanism onto the moving support and linking it with the turning mechanism, the material is simultaneously turned and mixed during feeding. This eliminates the need for additional feeding equipment and procedures, simplifying the organic fertilizer production process and improving the synergistic efficiency of feeding and turning. The long, narrow discharge port is parallel to the central axis of the spreading shaft, ensuring that the material flow direction matches the moving direction of the moving support, further improving feeding uniformity and preventing uneven feeding caused by material deviation.

[0027] 2. A synchronous belt drives the first synchronous pulley at the end of the rotating shaft to rotate, thereby causing the rotating shaft to rotate at a constant speed along its central axis. Several first turning blocks evenly arranged on the rotating shaft rotate synchronously with the rotating shaft, turning and stirring the fermenting material in the fermentation tank. After the feeding auxiliary mechanism evenly spreads the material on the surface of the fermenting material, the first turning blocks fully turn and mix the surface material with the original fermenting material at the bottom, so that the material is evenly distributed throughout the fermentation pile, preventing the material from just staying on the surface and not participating in fermentation. At the same time, the feeding mechanism, the feeding auxiliary mechanism, and the turning mechanism are linked by gears and synchronous belts to achieve synchronous "feeding-turning" to ensure that the material is mixed immediately after feeding. The synchronous belt linkage enables the coordinated operation of feeding and turning. After feeding is completed, the material can be immediately turned and mixed to prevent it from piling up on the surface of the fermenting material. This ensures that the feeding is evenly distributed throughout the fermentation pile, allowing every part of the fermenting material in the fermentation tank to fully contact the feeding. This effectively solves the problem of "rich surface and scarce bottom layer" feeding, further improving the uniformity of feeding during the process and ensuring stable fermentation parameters. The even distribution of the first turning block ensures that the turning range covers the entire cross-section of the fermentation tank, avoiding turning dead corners and further improving the mixing uniformity of the feeding and the original materials. No additional turning drive equipment is needed. The turning mechanism is linked by the driving force of the spreading shaft, simplifying the equipment structure, reducing equipment manufacturing costs and maintenance difficulty, while improving the coordination efficiency of feeding and turning, and shortening the production cycle.

[0034] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] This invention provides a turning device for organic fertilizer fermentation, such as... Figures 1 to 4As shown, the system includes a fermentation tank 1, a movable support 2 movably mounted on the fermentation tank 1 in a horizontal direction, and a material turning mechanism 3 mounted on the movable support 2. A material spreading mechanism 4 is mounted on the top of the movable support 2 in a horizontal direction. The material spreading mechanism 4 includes a material spreading cylinder 4a mounted on the movable support 2 in a horizontal direction and a material spreading shaft 4b rotatably mounted inside the material spreading cylinder 4a. Spiral material spreading blades 5 are mounted on the material spreading shaft 4b. A feed hopper 6 is connected to the top of the material spreading cylinder 4a. A long strip-shaped discharge port 7 is opened at the bottom of the material spreading cylinder 4a in a direction parallel to the central axis of the material spreading shaft 4b. A drive motor 8 for driving the material spreading shaft 4b to rotate is mounted on the movable support 2. A material spreading auxiliary mechanism 9 for expanding the material spreading area is mounted on the movable support 2. The material spreading auxiliary mechanism 9 is located directly below the discharge port 7.

[0036] Furthermore, the material spreading auxiliary mechanism 9 includes an auxiliary shaft 9a rotatably mounted on the movable support 2 in a direction parallel to the central axis of the material spreading shaft 4b, and a plurality of auxiliary blades 9b uniformly arranged on the auxiliary shaft 9a in a direction parallel to the central axis of the auxiliary shaft 9a. An open material spreading cavity 10 is formed between two adjacent auxiliary blades 9b.

The gear ratio of the first gear 11 and the second gear 12 is 1:2.

[0037] Furthermore, the material turning mechanism 3 includes a rotating shaft 3a rotatably mounted on the movable support 2 in a direction parallel to the central axis of the spreading shaft 4b, and a plurality of first material turning blocks 3b evenly arranged on the rotating shaft 3a. The end of the material turning shaft is provided with a first synchronous wheel 13, and the end of the auxiliary shaft 9a is provided with a second synchronous wheel 14. A synchronous belt 15 is provided between the first synchronous wheel 13 and the second synchronous wheel 14.

[0038] Furthermore, the radius of the first synchronous pulley 13 is smaller than the radius of the second synchronous pulley 14, and the transmission ratio between the first synchronous pulley 13 and the second synchronous pulley 14 is 1:3.

[0039] Furthermore, the auxiliary shaft 9a is symmetrically provided with first traveling wheels 16 at both ends, and the top of the movable support 2 is symmetrically provided with elongated moving grooves 17, with the bottom of the first traveling wheels 16 engaging with the moving grooves 17.

[0040] Furthermore, a first support block 18 is symmetrically arranged on one side of the movable support 2, and a second support block 19 is symmetrically arranged on the other side of the movable support 2. A second traveling wheel 20 that cooperates with the movable groove 17 is rotatably arranged at the bottom end of the first support block 18, and a third traveling wheel 21 that cooperates with the movable groove 17 is rotatably arranged at the bottom end of the second support block 19. The first traveling wheel 16 is located between the second traveling wheel 20 and the third traveling wheel 21.

[0041] Furthermore, a reinforcing plate 22 is fixedly provided between the first support block 18, the movable bracket 2, and the second support block 19, forming a support structure with a triangular longitudinal section between the first support block 18, the second support block 19, and the reinforcing plate 22.

[0042] Furthermore, a second turning block 23 is provided at the end of the first turning block 3b away from the rotating shaft 3a, and the cross-sectional area of ​​the second turning block 23 is greater than the cross-sectional area of ​​the first turning block 3b.

[0043] Furthermore, the movable support 2 is symmetrically provided with baffle frames 24 at both ends, and the first synchronous wheel 13, the second synchronous wheel 14, the first gear 11 and the second gear 12 are all located in the adjacent baffle frames 24 between the inner wall of the fermentation tank 1 and the spreading cylinder 4a.

[0044] Furthermore, the movable support 2 is symmetrically provided with baffles 25 on both sides in a downward direction, the auxiliary blade 9b is located between the two baffles 25, and the baffles 25 are located above the material turning mechanism 3.

[0045] During the organic fertilizer composting fermentation process, when an imbalance in the carbon-nitrogen ratio of the fermenting material in fermentation tank 1 is detected, requiring process replenishment, the material to be replenished (such as straw powder, microbial agents, dry manure, etc.) is put into the feed hopper 6 of the spreading mechanism 4. The drive motor 8 is started, and the drive motor 8 drives the spreading shaft 4b inside the spreading cylinder 4a to rotate at a uniform speed. The spiral spreading blades 5 on the spreading shaft 4b rotate synchronously, evenly pushing the material in the feed hopper 6 along the length of the spreading cylinder 4a. Under the squeezing action of the spiral blades, the material is evenly discharged from the long strip-shaped discharge port 7 at the bottom of the spreading cylinder 4a. As the material flows out rapidly, the second gear 12 at its end rotates synchronously with the material spreading shaft 4b. Through meshing with the first gear 11 at the end of the auxiliary shaft 9a (gear ratio 1:2), the auxiliary shaft 9a rotates at a constant speed along its central axis. Several auxiliary blades 9b evenly arranged on the auxiliary shaft 9a rotate synchronously, and the open-type material spreading chamber 10 formed between adjacent auxiliary blades 9b circulates and moves directly below the discharge port 7 to receive the material flowing out of the discharge port 7. Then, through the centrifugal force of the rotating auxiliary blades 9b, the material is evenly scattered to both sides, expanding the material spreading coverage. The width, along with a 1:2 tooth ratio, ensures precise matching between the material spreading and scattering speeds, preventing material accumulation or uneven scattering. As the auxiliary shaft 9a rotates, its two ends of the first traveling wheel 16 rotate synchronously. Since the first traveling wheel 16 engages with the elongated moving groove 17 at the top of the moving support 2, the rotating first traveling wheel 16 and the moving groove 17 form a rolling engagement, thereby driving the moving support 2 to move smoothly along the moving groove 17, i.e., along the horizontal direction of the fermentation tank 1. During the movement of the moving support 2, the second traveling wheel 20 at the bottom of the first support block 18 on one side and the third traveling wheel 21 at the bottom of the second support block 19 on the other side roll in conjunction with the first traveling wheel 16, forming a triangular distribution support to ensure the horizontal stability of the moving support 2 and prevent tilting or deviation. Simultaneously, the reinforcing plate 22 between the first support block 18, the moving support 2, and the second support block 19 forms a triangular support structure, improving the overall rigidity of the moving support 2, preventing structural deformation, ensuring the relative positional stability of the spreading and moving mechanisms, achieving synchronous coordination of spreading and moving, covering the entire area of ​​the fermentation tank 1, and preventing gaps or localized accumulation in the material supply.Simultaneously, when the auxiliary shaft 9a rotates, its second synchronous wheel 14 drives the first synchronous wheel 13 at the end of the rotating shaft 3a to rotate via the synchronous belt 15. Since the radius of the first synchronous wheel 13 is smaller than that of the second synchronous wheel 14, the transmission ratio is 1:3. When the auxiliary shaft 9a rotates one revolution, the rotating shaft 3a rotates three revolutions. The auxiliary shaft 9a drives the material spreading auxiliary mechanism 9 to slowly spread the material, and the rotating shaft 3a drives the first turning block 3b on it to quickly turn and spread the material. The second turning block 23 at the end of the first turning block 3b (with a cross-sectional area larger than the first turning block 3b) expands the turning range and increases the turning force, quickly and evenly turning the supplementary material spread on the surface of the fermented material into the bottom layer, fully mixing it with the original fermented material, and avoiding the need for supplementary material to be added. The surface layer of the material is enriched to ensure that the feed is evenly distributed throughout the fermentation pile. The material baffles 24 at both ends of the movable support 2 seal the transmission components such as the first synchronous wheel 13, the second synchronous wheel 14, the first gear 11, and the second gear 12 inside, preventing fermentation material and dust from entering the transmission gap, avoiding transmission jamming and wear, and ensuring stable rotational speed of each shaft. The baffles 25 set diagonally downward on both sides of the movable support 2 wrap the auxiliary blades 9b within them, preventing the material from splashing excessively to both sides and guiding the material to fall accurately into the fermentation tank 1. At the same time, it prevents the material from splashing upward during the turning process, preventing the material from adhering to the spreading mechanism 4 and the transmission components, ensuring stable operation of the equipment, and further improving the uniformity of feeding.

[0046] Through the coordinated design of "spiral spreading and pushing + auxiliary blade 9b sprinkling + mobile support 2 linkage", the core pain points of traditional manual sprinkling and feeding are solved: "local accumulation and omissions". The spiral spreading blade 5 ensures uniform and continuous material flow, and the long strip-shaped discharge port 7 ensures uniform linear discharge. The design of the auxiliary blade 9b and the sprinkling chamber 10 transforms the linear discharge into uniform lateral diffusion, expanding the sprinkling width. The auxiliary shaft 9a, linked with the first traveling wheel 16, drives the mobile support 2 to move smoothly. With the help of the triangular support structure, the movement is stable, realizing uniform feeding throughout the length and width of the fermentation tank 1. This ensures that the carbon-nitrogen ratio and material composition of the fermented material are consistent in all areas of the fermentation tank 1, greatly improving the uniformity of process feeding.

[0047] Through the linkage design of gears and synchronous belts 15, the three major actions of spreading, moving, and turning are synchronized. The spreading auxiliary mechanism 9 slowly spreads the material to ensure even spreading, while the turning mechanism 3 quickly turns the material to ensure that the supplementary material is fully mixed with the original fermentation material. The 1:3 synchronous wheel transmission ratio and the 1:2 gear tooth ratio achieve precise matching of the speed of each mechanism, avoiding material accumulation, splashing, or uneven mixing, effectively solving the problem of "rich surface and poor bottom layer of supplementary material", and further improving the uniformity and effectiveness of supplementary material.

[0048] The protective design of the baffle frame 24 and the shielding plate 25 prevents the transmission components from jamming and the material from splashing, ensuring the stable operation of each mechanism. The triangular support structure and multiple wheels provide support to prevent the moving support 2 from tilting or deforming, ensuring the precise relative position of the spreading mechanism 4 and the spreading auxiliary mechanism 9, and the precise docking of the discharge port 7 and the spreading chamber 10. The spreading angle and moving speed are stable. From the perspective of equipment structure and operational stability, the uniformity of material replenishment is guaranteed, and material replenishment deviation caused by equipment failure or offset is avoided.
