Description

Technical Field

[0001] This invention relates to the field of composting technology, specifically to a composting device and method for natural fermentation of microbial agents. Background Technology

[0002] Natural fermentation using microbial agents refers to the process of biodegrading and transforming organic waste using specific functional microbial communities under suitable temperature, humidity, and aeration conditions. It is widely used in organic fertilizer production, sludge treatment, and the resource utilization of agricultural waste. However, during natural fermentation, uneven oxygen distribution can lead to localized anaerobic putrefaction, large temperature gradients can cause incomplete fermentation, and moisture migration can be hindered. Therefore, it is essential to periodically turn and mix the materials to force oxygen replenishment, evenly dissipate heat and moisture, break up material clumps, and promote microbial activity, thereby ensuring efficient, uniform, and odorless fermentation.

[0003] However, the following problems still exist in the process of turning over the inoculant materials: Current methods for turning and crushing fermented materials often involve turning and crushing simultaneously. However, fermented materials are highly viscous and prone to caking, and the size distribution of clumps is extremely uneven. Direct crushing without prior screening results in excessive crushing of fine particles due to repeated rolling, while large clumps are not fully crushed because they cannot easily enter the crushing zone or are not subjected to sufficient force. This leads to an imbalance in the crushing effect, which not only wastes energy but also damages the pore structure of the material, reducing fermentation uniformity and oxygen supply efficiency.

[0004] Currently, most crushing mechanisms adopt a fixed-strength, unidirectional shearing or extrusion mode, applying the same crushing force regardless of the material size. This causes fine materials to be easily crushed into mud, affecting air permeability, while large materials are difficult to effectively deagglomerate due to insufficient shear stroke or unidirectional action. Ultimately, this results in uneven pile structure and large differences in microbial metabolic environment, seriously affecting the quality of turning, fermentation consistency and overall processing efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a turning device and method for natural fermentation of microbial agents, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a natural fermentation and turning device for microbial agents, comprising: a machine frame; a wedge-shaped screening chamber, wherein the wedge-shaped screening chamber is located below the machine frame, and an annular chain plate is fitted on the outer side of the wedge-shaped screening chamber. Several rectangular slots are evenly distributed along the circumference of the annular chain plate. A material discharge channel is provided on the inclined section of the wedge-shaped screening chamber, and a grid plate is sequentially arranged along the inclined direction within the material discharge channel, with the mesh aperture of the grid plate gradually increasing from bottom to top; a shearing and crushing assembly, wherein multiple shearing and crushing assemblies are arranged in the internal cavity of the wedge-shaped screening chamber, each corresponding to one of the grid plates, for shearing the material that falls into the chamber after being screened by the grid plates; and a receiving conveyor belt, wherein the receiving conveyor belt is inclinedly arranged below the shearing and crushing assembly for receiving the sheared material and conveying it to the back side area of ​​the vertical section of the wedge-shaped screening chamber.

[0007] Furthermore, the shearing and crushing assembly consists of multiple circumferentially evenly distributed angled shearing blades. The lower end of the inclined section of the angled shearing blade is hinged to the fixed base, and a connecting rod is hinged at the corner of the angled shearing blade. The other end of the connecting rod is hinged to the sliding base, and a cross blade is provided in the middle of the upper end of the sliding base.

[0008] Furthermore, the shearing and crushing assembly consists of multiple circumferentially evenly distributed angled shearing blades. The lower end of the inclined section of the angled shearing blade is hinged to the fixed base, and a connecting rod is hinged at the corner of the angled shearing blade. The other end of the connecting rod is hinged to the sliding base, and a multi-directional extrusion blade is provided in the middle of the upper end of the sliding base.

[0009] Furthermore, the multi-directional extrusion blade includes multiple circumferentially evenly distributed triangular prisms, each triangular prism and the angled shearing blade are arranged alternately along the circumferential direction, and the side of the triangular prism near the angled shearing blade is provided with an inclined surface.

[0010] Furthermore, the shearing and crushing assembly also includes a movable shaft, a triangular slider is installed at the lower end of the movable shaft, a wedge plate is provided below the triangular slider, the inclined surface of the triangular slider slides into contact with the inclined surface of the wedge plate, and the contact directions of two adjacent sets of triangular sliders and wedge plates are opposite.

[0011] Furthermore, a horizontal frame is provided between the grid plate and the shearing and crushing component. The upper end of the horizontal frame is provided with evenly distributed levers, and a rotating shaft fixedly connected to the grid plate is rotatably installed in the middle of the horizontal frame, allowing the horizontal frame to reciprocate around the rotating shaft.

[0012] Furthermore, the horizontal frame is equipped with sliding plates that slide in cooperation with the wedge-shaped screening chamber at both ends. The outer wall of the wedge-shaped screening chamber is equipped with an arc-shaped groove plate. The sliding plate is equipped with a sliding column that slides in cooperation with the arc-shaped groove plate. The upper end of the arc-shaped groove plate is provided with a rectangular groove plate that slides in cooperation with the sliding column.

[0013] Furthermore, baffles fixedly installed inside the wedge-shaped screening chamber are respectively provided on both sides of the material discharge chute along the length direction. A movable rod that slides with the wedge-shaped screening chamber is provided at the lower end of the baffle near the vertical section of the wedge-shaped screening chamber. Evenly distributed dividing blades are installed at the lower end of the movable rod.

[0014] Furthermore, after the front end of the moving rod passes through the wedge-shaped screening chamber, an inclined surface fixing block is installed. An inclined surface slider is provided on the front side of the inclined surface fixing block, and the inclined surface of the inclined surface slider slides in cooperation with the inclined surface of the inclined surface fixing block.

[0015] This invention also provides a method for turning over a compost pile during natural fermentation of microbial agents, applicable to a compost pile turning device for natural fermentation of microbial agents, comprising the following steps: Step 1: The machine's working frame drives the wedge-shaped screening chamber to move along the length of the fermentation tank, while simultaneously activating the annular chain plate to make it run in a closed loop around the outer periphery of the wedge-shaped screening chamber; Step 2: The running ring chain plate scoops up the material at the bottom of the fermentation tank and lifts it to a high position. The material falls into the material discharge chute under the action of gravity and is screened by the grid plate. The material with smaller particle size falls through the lower grid plate and the material with larger particle size falls through the upper grid plate. Step 3: The material falling through the screen enters the internal cavity of the wedge-shaped screening chamber, where the shearing and crushing components perform corresponding shearing and crushing treatment. Step 4: The material after shearing and crushing falls into the receiving conveyor belt below, which then transports and throws it into the fermentation tank area on the back side of the vertical section of the wedge-shaped screening bin, completing one turning operation.

[0016] The present invention has the following beneficial effects: (1) The natural fermentation turning device of the microbial agent realizes simultaneous conveying and grading by setting a wedge-shaped screening bin during the material conveying process: the material falls through the rectangular channel and the discharge channel in sequence under the push of the ring chain plate. With the help of the grid plate with the aperture gradually increasing from bottom to top, small particles are screened into the bin at the low position, while large pieces are sent to the corresponding aperture at the high position to fall. Thus, efficient and orderly gradient screening is completed in continuous movement, providing a stable supply of particle size matching and uniform distribution for subsequent crushing.

[0017] (2) The natural fermentation turning device of the microbial agent is equipped with shearing and crushing components that correspond one-to-one with each layer of grid plate in the wedge-shaped screening chamber, so that materials of different particle sizes fall directly into the matching shearing area and are dynamically sheared in a targeted, periodic and multi-directional manner by the corresponding blades. This avoids the fine material from being too crushed and ensures that the large pieces are fully crushed, resulting in uniform output particle size and loose structure, thereby improving fermentation uniformity, turning efficiency and oxygen supply effect.

[0018] (3) The natural fermentation turning device of the microbial agent achieves staggered shearing action by making adjacent groups of angled shearing blades in different opening and closing phases, which effectively prevents the material from slipping due to unidirectional force and significantly improves the stability and uniformity of the crushing process. At the same time, the arrangement density of the angled shearing blades in each layer decreases from top to bottom. The upper layer adopts a high-density arrangement to perform strong and dense shearing on large clumps, while the lower layer adopts a sparse layout to only moderately process the small particles that have been screened, avoiding over-crushing. As a result, large pieces of material are efficiently refined in the upper layer, and small pieces of material maintain a reasonable particle size in the lower layer. The final output particle size distribution is uniform and the structure is loose, and the overall crushing effect is consistent.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0024] The following reference Figures 1-13 This invention describes the microbial agent natural fermentation turning device and turning method provided in the embodiments of the present invention.

[0025] On the one hand, the present invention provides a device for turning over the natural fermentation of microbial agents.

[0026] Example 1, please refer to this example. Figures 1-12 .

[0027] Please refer to Figure 1 and Figure 2This microbial agent natural fermentation turning device is suitable for trough fermentation. It includes a whole machine working frame 2 spanning tracks on both sides of the fermentation trough 1, which can move along the length of the trough. A wedge-shaped screening chamber 3 is suspended below the whole machine working frame 2. A ring-shaped chain plate 31 is fitted on the outside of the wedge-shaped screening chamber 3. The whole machine working frame 2 integrates a hydraulic system and a drive component (not specifically shown in the figure). The hydraulic system is used to control the vertical lifting and lowering of the wedge-shaped screening chamber 3, so that it slowly enters the area to be turned in the fermentation trough 1 (usually the blank area) to reduce the disturbance to the active material. At the same time, the drive component drives the ring-shaped chain plate 31 to rotate continuously counterclockwise. During the operation, the ring-shaped chain plate 31 grabs the material at the bottom of the trough upward and conveys it obliquely to a higher position along the inclined surface of the wedge-shaped screening chamber 3, forming a continuous and stable material flow, providing a reliable feeding basis for subsequent screening and crushing processes.

[0028] Please refer to Figure 3 and Figure 5 Because the material in the fermentation tank 1 is highly viscous and prone to caking, in order to improve the uniformity of turning and processing efficiency, the wedge-shaped screening bin 3 can simultaneously complete the grading and screening during the material conveying process. Specifically, several rectangular through slots 311 are evenly opened along the circumference on the annular chain plate 31. Since the annular chain plate 31 is in close contact with the wedge-shaped screening bin 3, while ensuring its ability to continuously grab and convey materials, the material is allowed to pass through the rectangular through slots 311. Correspondingly, a material drop slot is opened on the inclined section of the wedge-shaped screening bin 3. When the annular chain plate 31 carries the material through this area, the material, under the action of gravity and the thrust of the annular chain plate 31, passes through the rectangular through slots 311 and the material drop slot in sequence and falls into the wedge-shaped screening bin 3.

[0029] Please refer to Figure 3 and Figure 5 To achieve precise grading, grid plates 32 are sequentially installed along the inclined direction in the material discharge channel, and the mesh size of the grid plates 32 gradually increases from bottom to top. Smaller particles can pass through the fine mesh plates 32 and fall into the bin at the lower position of the conveying path, while larger lumps are continued to be conveyed upward until they reach the larger mesh plate 32 that matches their size before falling in. In this way, materials of different particle sizes complete efficient and orderly gradient screening in continuous movement.

[0030] Please refer to Figure 3 , Figure 4 and Figure 7To ensure that materials of different particle sizes after screening receive shearing and crushing treatment that matches their dimensions, thereby improving the uniformity of turning and the efficiency of operation, shearing and crushing components 33 are installed in the cavity inside the wedge-shaped screening chamber 3. Multiple sets of shearing and crushing components 33 are installed and correspond one-to-one with the grid plates 32. When the material after being classified by the grid plates 32 falls into the wedge-shaped screening chamber 3, the material of different grades falls directly into the corresponding shearing area and is targeted by the corresponding shearing and crushing components 33 for shearing and crushing. This avoids over-crushing of fine materials or insufficient crushing of large pieces, ensuring uniform particle size and loose structure of the output, and effectively improving the quality of turning and the oxygen supply efficiency.

[0031] Please refer to Figures 7-10 Specifically, the shearing and crushing assembly 33 consists of multiple circumferentially evenly distributed angled shearing blades 331. The lower end of the inclined section of the angled shearing blade 331 is hinged to the fixed base 332, and a connecting rod 333 is hinged at the corner of the angled shearing blade 331. The other end of the connecting rod 333 is hinged to the sliding base 334. When the sliding base 334 moves downward, it drives the multiple connecting rods 333 to move downward synchronously, thereby pulling each angled shearing blade 331 inward around its hinge point with the fixed base 332. The oscillating motion applies a shearing action in an inclined direction to the material falling between them. The sliding seat 334 can move up and down reciprocally, causing the angled shearing blade 331 to open and close periodically, thereby continuously performing dynamic shearing on the material, effectively breaking up sticky lumps and improving the looseness of the material. At the same time, the connecting rod 333 travels between the materials as it oscillates with the angled shearing blade 331. Its rod body applies disturbance and local compression to the material, which helps to break up slight clumps and improves the overall crushing efficiency in conjunction with the main shearing action.

[0032] Please refer to Figure 3 and Figure 7 In this case, each fixed seat 332 in the same group of shearing and crushing components 33 is installed on the same fixed plate 335. The fixed plate 335 is fixedly installed on the inner wall of the wedge-shaped screening chamber 3 to ensure the overall structure of the shearing and crushing components 33 is stable and the force is balanced.

[0033] Please refer to Figure 7 and Figure 8 A cross blade 336 is provided at the middle of the upper end of the sliding seat 334. The cross blade 336 can move up and down synchronously with the sliding seat 334. When the angled shearing blade 331 closes inward, its cutting edge and the cutting edge of the cross blade 336 form an interlocking shearing pair, thereby achieving multi-directional cutting when the material passes through, further improving the crushing uniformity and shearing efficiency.

[0034] Please refer to Figure 7 and Figure 9To enable the sliding seat 334 to move, a moving shaft 337 that slides through the fixed seat 332 is installed at the lower end of the sliding seat 334. A triangular slider 338 is installed at the lower end of the moving shaft 337. A wedge plate 339 is provided below the triangular slider 338. The inclined surface of the triangular slider 338 and the inclined surface of the wedge plate 339 slide in cooperation. The wedge plate 339 in the same shearing and crushing assembly 33 is installed on the same moving plate 340. When the moving plate 340 moves back and forth in the horizontal direction, the relative sliding of the wedge plate 339 pushes each triangular slider 338 to move up and down synchronously, thereby driving the moving shaft 337 and the sliding seat 334 connected to it to move up and down reciprocally.

[0035] Please refer to Figure 7 To further improve the shearing and crushing effect, the adjacent sets of triangular sliders 338 and wedge plates 339 are aligned in opposite directions. In the initial state, the adjacent sets of angled shear blades 331 are in different opening and closing phases. When the moving plate 340 moves horizontally back and forth, since the inclined surfaces of the adjacent wedge plates 339 are in opposite directions, the vertical component of the force on each triangular slider 338 is also in opposite directions. This causes the adjacent sets of angled shear blades 331 to open and close alternately, forming a staggered shearing action. This effectively prevents the material from slipping due to unidirectional force and improves the crushing uniformity and processing efficiency.

[0036] In addition, by adjusting the initial engagement position between each wedge plate 339 and the corresponding triangular slider 338, the opening and closing phases of different groups of angled shearing blades 331 in the initial state can be made different. When the moving plate 340 moves, each group of angled shearing blades 331 moves in sequence according to their phase difference, forming a multi-phase, asynchronous opening and closing motion, which further enhances the staggered shearing effect and improves the crushing uniformity and processing efficiency of complex agglomerated materials.

[0037] Please refer to Figure 8 and Figure 10 It should be noted that, in order to ensure stable cooperation and reliable operation of moving parts such as the angled shearing blade 331, connecting rod 333, triangular slider 338 and wedge plate 339 during operation, flexible protective covers can be wrapped around each hinge or sliding joint to prevent fermentation material from entering the gaps between moving parts and avoid jamming or wear. At the same time, inverted conical cylinders are provided at the upper ends of the sliding seat 334 and the fixed seat 332. The outwardly expanding inclined surface of the cylinders guides the material to slide down, effectively preventing the material from accumulating on the top of the seat and ensuring the long-term stable operation of the mechanism.

[0038] Please refer to Figure 7To match the screening characteristics of the progressively increasing aperture of the mesh plates 32 from top to bottom, the density of the angled shear blades 331 arranged in the shearing and crushing component 33 decreases from top to bottom. The upper layer corresponds to larger materials, and a high-density blade arrangement is used to fully shear large clumps through dense cutting edges. The lower layer corresponds to smaller materials, and a lower-density blade arrangement is used to moderately crush small materials to avoid over-crushing. As a result, large materials are efficiently refined in the upper layer, while small materials maintain their original particle size in the lower layer, ultimately making the output particle size more uniform, the overall crushing effect more consistent, and the energy consumption more reasonable.

[0039] Please refer to Figure 4 and Figure 6 To ensure that the material can pass smoothly through the grid plate 32 and enter the wedge-shaped screening chamber 3, a horizontal frame 34 is set between the grid plate 32 and the shearing and crushing component 33. The upper end of the horizontal frame 34 is equipped with evenly distributed levers 341. The middle of the horizontal frame 34 is rotatably mounted with a rotating shaft 342 that is fixedly connected to the grid plate 32. The horizontal frame 34 can reciprocate around the rotating shaft 342. When the material falls through the discharge chute, the horizontal frame 34 drives the levers 341 to swing synchronously, quickly moving and dispersing the material falling into the chute. On the one hand, this prevents the material from accumulating and blocking under the grid plate 32, and on the other hand, it applies a preliminary crushing effect to the agglomerated material, providing looser and more uniform feeding conditions for subsequent shearing processing.

[0040] Please refer to Figure 6 and Figure 11 To achieve the reciprocating rotation of the horizontal frame 34 around the pivot 342, slide plates 343 that slide in cooperation with the wedge-shaped screening chamber 3 are installed at both ends of the horizontal frame 34. An arc-shaped groove plate 344 is installed on the outer wall of the wedge-shaped screening chamber 3. A sliding column that slides in cooperation with the arc-shaped groove plate 344 is installed on the slide plate 343. A rectangular groove plate 345 that slides in cooperation with the sliding column is provided at the upper end of the arc-shaped groove plate 344. When the rectangular groove plate 345 moves reciprocally in the horizontal direction, it drives the sliding column to move reciprocally along the trajectory of the arc-shaped groove plate 344. In turn, the sliding column pushes the slide plate 343 to swing on the arc path, thereby driving the horizontal frame 34 to reciprocate around the pivot 342 in the middle, and finally realizing the continuous agitation and disturbance of the material in the discharge channel by the lever 341.

[0041] Please refer to Figures 3-5Inside the wedge-shaped screening bin 3, a receiving conveyor belt 35 is installed. The receiving conveyor belt 35 is inclined and located below the shearing and crushing component 33 to receive the material after shearing. The receiving conveyor belt 35 is driven by an existing drive source (not specifically shown in the figure) to transport the crushed material upward and throw it to the back area of ​​the vertical section of the wedge-shaped screening bin 3. The vertical section of the wedge-shaped screening bin 3 at the corresponding position is provided with a discharge channel to ensure that the material is discharged smoothly. At the same time, the running path of the ring chain plate 31 does not interfere with the discharge area, ensuring that the discharge process is continuous and stable, realizing the directional transfer and orderly stacking of materials, and providing a smooth discharge channel for the continuous turning and stacking operation of the whole machine.

[0042] Please refer to Figures 3-5 To ensure that the material passes through the lever 341 and the shearing and crushing component 33 sequentially and orderly after passing through the material discharge chute, baffles 351 fixedly installed inside the wedge-shaped screening chamber 3 are provided on both sides of the material discharge chute along the length direction. This ensures that the material is always constrained between the two baffles 351 during the falling and conveying process until it enters the receiving conveyor belt 35 area.

[0043] Please refer to Figure 5 , Figure 11 and Figure 12 To further improve the uniformity of turning and piling, a movable rod 352 that slides with the wedge-shaped screening bin 3 is provided at the lower end of the baffle 351 near the vertical section of the wedge-shaped screening bin 3. The lower end of the movable rod 352 is equipped with evenly distributed dividing blades 353. When the receiving conveyor belt 35 conveys the crushed material upward, the dividing blades 353 are simultaneously inserted into the material layer to perform lateral separation and sorting of the material, so that it is more evenly scattered to the outside of the bin, avoiding accumulation and concentration, thereby achieving efficient and uniform turning and piling of the material.

[0044] Please refer to Figure 9 and Figure 10 The moving rod 352 can move back and forth in the front and back direction. Its front end passes through the wedge-shaped screening chamber 3 and is equipped with an inclined surface fixing block 354. An inclined surface slider 355 is provided on the front side of the inclined surface fixing block 354. The inclined surface of the inclined surface slider 355 slides and engages with the inclined surface of the inclined surface fixing block 354. When the inclined surface slider 355 moves back and forth, the horizontal displacement is converted into the back and forth movement of the inclined surface fixing block 354 and the moving rod 352 through the relative sliding between the two inclined surfaces. This drives the separator blade 353 at its lower end to move back and forth synchronously, so as to realize the dynamic separation and uniform spreading of materials.

[0045] Please refer to Figure 2 and Figure 11To improve the overall efficiency of the machine, the moving plate 340, the rectangular groove plate 345 and the inclined slider 355 can move back and forth synchronously. Specifically, a vertical rod 36 is connected between the moving plate 340 and the rectangular groove plate 345. Adjacent vertical rods 36 are fixedly connected by a horizontal rod 361. The inclined slider 355 is connected to the corresponding vertical rod 36 through an L-shaped connecting rod 362. The uppermost vertical rod 36 is connected to the output end of the cylinder 363. The cylinder 363 is fixedly installed outside the wedge-shaped screening chamber 3.

[0046] When the cylinder 363 extends or retracts, the driving force is transmitted through the vertical rod 36, the horizontal rod 361 and the L-shaped connecting rod 362, which simultaneously drives the moving plate 340, the rectangular groove plate 345 and the inclined slider 355 to reciprocate in the horizontal direction, thereby realizing the coordinated action of shearing drive, lever 341 swing and material separation, and improving the continuity and stability of turning operation.

[0047] It should be noted that the figure only shows part of the structure of the wedge screening chamber 3. In actual application, the wedge screening chamber 3 has a large overall height, and its external drive mechanism is arranged on the material layer of the fermentation tank 1, without direct contact with the material in the tank, thereby avoiding contamination of the drive components and ensuring operational reliability.

[0048] In actual operation (use), the machine's working frame 2 moves along the length of the fermentation tank 1, while simultaneously activating the annular chain plate 31 to operate in a closed loop around the outer periphery of the wedge-shaped screening chamber 3. The annular chain plate 31 continuously grabs and lifts the material from the bottom of the tank to a high position. Under the action of gravity, the material falls into the discharge chute and undergoes gradient screening through multiple layers of mesh plates 32 during its descent. Smaller particles are screened and fall through the lower mesh plate 32, while larger particles are screened and fall through the upper mesh plate 32. The screened material then enters the internal cavity of the wedge-shaped screening chamber 3 according to its grade, where it is further processed by the corresponding shearing and crushing components 33. The shearing process ensures uniform particle size of the output material. At the same time, the horizontal frame 34 drives the lever 341 to swing back and forth to prevent material from clogging in the screening area. The crushed material falls into the inclined receiving conveyor belt 35 below, which is then conveyed upward and thrown into the fermentation tank 1 area on the back side of the vertical section of the wedge-shaped screening bin 3. During this process, the moving rod 352 drives the separating blade 353 to reciprocate synchronously, which laterally separates and spreads the material on the receiving conveyor belt 35, making the material distribution more uniform after turning over. This efficiently completes the continuous turning over operation that integrates digging, screening, crushing, conveying and reconstructing the pile.

[0049] Example 2, please refer to this example. Figure 13 .

[0050] The difference between this embodiment and Embodiment 1 is that a multi-directional extrusion blade 346 is provided at the upper center of the sliding seat 334. The multi-directional extrusion blade 346 includes multiple circumferentially evenly distributed triangular prisms. Each triangular prism and the angled shearing blade 331 are arranged alternately along the circumference. The side of the triangular prism closest to the angled shearing blade 331 is provided with an inclined surface. It should be noted that the triangular prism is made of lightweight material and has a light overall weight, so it will not cause additional burden on the reciprocating motion of the sliding seat 334.

[0051] When the sliding seat 334 moves up and down, the angled shearing blade 331 moves inward or outward simultaneously. At the same time, the multi-directional extrusion blade 346 moves up and down synchronously with the sliding seat 334, forming a dynamic interlocking action with the angled shearing blade 331 during the movement. Specifically, when the angled shearing blade 331 swings, its cutting edge moves closer to the inclined surface of the adjacent triangular prism, applying shearing and extrusion actions in opposite directions to the material, achieving multi-directional kneading and crushing. In addition, the material falling into the top of the triangular prism can naturally slide down its inclined surface to the effective working area of ​​the angled shearing blade 331, avoiding material retention and further improving the crushing uniformity and processing efficiency.

[0052] On the other hand, the present invention also provides a method for turning over the compost pile during natural fermentation of microbial agents, applicable to a device for turning over the compost pile during natural fermentation of microbial agents, combined with... Figures 1-3 This includes the following steps: Step 1: The machine frame 2 drives the wedge-shaped screening chamber 3 to move along the length of the fermentation tank 1, and at the same time, the ring chain plate 31 is activated to make it run in a closed loop around the outer periphery of the wedge-shaped screening chamber 3; Step 2: The running ring chain plate 31 scoops up the material at the bottom of the fermentation tank 1 and lifts it to a high place.
