Description

Technical Field

[0001] This invention relates to the field of organic fertilizer preparation technology, specifically to an agricultural waste treatment device for organic fertilizer preparation. Background Technology

[0002] In the process of preparing organic fertilizer from aerobic fermentation of agricultural waste, the turning of materials is the core and key process that determines the uniformity of fermentation and the quality of decomposition. A reasonable layered and fully covered turning method can ensure that the materials in the deep and shallow layers of the fermentation tank can be breathed, dissipated and decomposed at the same time.

[0003] Most conventional organic fertilizer turning equipment on the market currently adopts a fixed single-height turning structure, which can only achieve planar turning operations with a single trajectory and height. The equipment lacks the ability to perform multi-height, stepped operations and cannot complete reciprocating turning operations with forward and reverse switching. However, agricultural waste in actual fermentation tanks is stacked in a three-dimensional, stratified state. The density, aeration conditions, fermentation temperature, and maturity progress of the shallow, middle, and deep layers of material all differ significantly. The traditional uniform-height turning mode cannot adapt to the differentiated fermentation needs of materials at different depths. Conventional equipment operation easily leads to repeated turning of shallow materials and neglect of turning of deep materials. Corners and deep materials in the fermentation tank easily form solidified fermentation dead zones, resulting in the industry-wide problem of large differences in material stratification and poor overall turning uniformity. Ultimately, this leads to uneven maturity of organic fertilizer materials, weak fermentation stability, significantly reduced quality of the finished organic fertilizer, and a prolonged overall fermentation production cycle, making it difficult to meet the production needs of large-scale, high-quality organic fertilizer. Summary of the Invention

It can perform differentiated turning and covering of shallow, medium and deep materials in the fermentation tank, completely avoiding fermentation dead zones caused by turning at a single height, effectively solving the problems of uneven material turning and large differences in layered fermentation, and greatly improving the uniformity and composting effect of agricultural waste fermentation. 2. This invention utilizes a PLC controller in conjunction with an angle adjustment structure consisting of a hydraulic cylinder, a rack and pinion, and a spur gear, combined with a stepped layout of multiple turning frames, to achieve layered gradient angle turning operations throughout the entire fermentation cycle of organic fertilizer. The tilt angle of the C-shaped turning rod can be adaptively adjusted according to different stages of fermentation, such as heating, high temperature, and cooling and maturation, to precisely adapt to the fermentation conditions of materials at different depths.

The following describes embodiments of the invention based on its overall structure.

[0019] In the fermentation production process of organic fertilizer from agricultural waste, traditional turning equipment operates in a fixed and monotonous manner, often employing a flat turning method with a uniform height and fixed trajectory. This fails to provide layered and comprehensive turning of agricultural waste at different depths and in different areas within the fermentation tank. During operation, problems such as excessive turning of surface materials, insufficient turning of middle and deeper materials, and the existence of fermentation dead zones easily occur, directly resulting in uneven overall fermentation, poor aeration and oxygen permeability of the material layer, and significantly reducing the fermentation efficiency and quality of the finished organic fertilizer. Furthermore, traditional turning structures are ineffective at breaking up clumps of accumulated agricultural waste, leading to significant material compaction and further hindering oxygen penetration and microbial growth, severely impacting the composting effect. Therefore, this solution proposes the following technical improvements: Please see Figures 1-9This embodiment provides an agricultural waste treatment device for organic fertilizer preparation, including: a gantry frame 1 and multiple longitudinal linear modules installed on the top of the gantry frame 1. Each longitudinal module has a transverse linear module 2 installed at its execution end, and a vertical linear module 3 is installed at the execution end of the transverse linear module 2. A turning frame 4 is installed at the straight end of the vertical linear module 3. The height difference of the multiple turning frames 4 is stepped, which is used to perform gradient turning treatment during the fermentation process of agricultural waste to prepare organic fertilizer. A turning roller 8 is provided, which rotates continuously. A servo motor 6 is installed on the top of the throwing frame 4, and a synchronous wheel 5 is fixedly connected to one end of the throwing roller 8 through the end of the throwing frame 4. The output end of the servo motor 6 is also equipped with a synchronous wheel 5. A synchronous belt 7 is installed on the outer wall of the two synchronous wheels 5. There are multiple auxiliary seats 10, and multiple throwing rollers 8 are arranged in a ring on the outside of the throwing roller 8. A C-shaped throwing rod 11 is fixedly connected to the end of each auxiliary seat 10. Multiple tapered rods 13 are fixedly connected to the inner side of the C-shaped throwing rod 11. Using the gantry frame 1 as the overall load-bearing installation base, multiple sets of longitudinal linear modules are evenly assembled on the top of the gantry frame 1. Each set of longitudinal linear modules has a transverse linear module 2 installed at its execution end, and a vertical linear module 3 is installed at the execution end of the transverse linear module 2. The three linear modules cooperate with each other to form a multi-dimensional high-precision linkage displacement mechanism, which can realize the all-round position adjustment of the throwing frame 4 in the transverse, longitudinal, and vertical directions, providing stable structural support for full-area, layered, and reciprocating throwing operations. The throwing frame 4 is fixedly installed at the linear working end of each set of vertical linear modules 3. The throwing frame 8 is rotatably connected to the inner side of the throwing frame 4. A servo motor 6 is fixedly installed on the top of the throwing frame 4. Synchronous pulleys 5 are fixedly installed at the output end of the servo motor 6 and the end of the throwing roller 8. A synchronous belt 7 is sleeved between the two synchronous pulleys 5 to form a stable synchronous transmission structure, providing a reliable power source for the continuous uniform rotation of the throwing roller 8. Multiple sets of auxiliary seats 10 are evenly distributed in a ring on the outer side of the turning roller 8. Each auxiliary seat 10 is fixedly connected to a C-shaped turning rod 11 at its end. Multiple tapered rods 13 are densely fixed on the inner side of the C-shaped turning rod 11. During operation, the servo motor 6 is started. The servo motor 6 drives the turning roller 8 to rotate in a uniform circular motion inside the turning frame 4 through the synchronous transmission action of the synchronous pulley 5 and the synchronous belt 7. This drives the multiple sets of C-shaped turning rods 11 distributed in a ring on the outer side to rotate in a synchronous circular motion, continuously grabbing, lifting, turning over and loosening the agricultural waste materials inside the fermentation tank. The multiple sets of turning frames 4 adopt an initial stepped height difference layout structure. During operation, the PLC control system coordinates and controls the operation of the three-axis linear modules. The longitudinal linear module at the top of the gantry 1 drives the overall turning mechanism to complete longitudinal displacement, while the transverse linear module 2 drives the turning frames 4 to achieve precise transverse movement. The vertical linear module 3 precisely fixes the stepped height of each set of turning frames 4. Relying on the height difference characteristics of the multiple sets of turning frames 4, the materials in the shallow, middle, and deep layers of the fermentation tank can be turned in a gradient layer simultaneously, covering the entire working area of ​​the fermentation tank at one time. This completely eliminates the fermentation dead zones that exist in traditional single-height turning, and achieves synchronous and uniform turning of materials at different depths, ensuring the basic uniformity of material fermentation. After the device completes the single-wheel lateral full-coverage, forward-stepping turning operation, the control system regulates the independent operation of each set of vertical linear modules 3, adjusting the working height of multiple sets of turning frames 4 in the opposite direction, so that the multiple sets of turning frames 4 form a reverse stepping height distribution. Subsequently, in conjunction with the longitudinal linear module at the top of the gantry frame 1, the overall turning mechanism is driven to complete the reverse longitudinal movement, realizing bidirectional stepping reciprocating turning operation. Through the operation mode of forward and reverse cross-layered turning, the material in the fermentation tank is turned in a multi-level, all-round circulation, further enhancing the uniformity of material turning, completely solving the problem of insufficient fermentation and uneven maturity of local materials, and comprehensively optimizing the fermentation environment.

[0020] In the fermentation process of agricultural waste organic fertilizer, the traditional turning devices mostly have fixed and non-adjustable turning angles, which can only achieve material turning operations at a single angle and amplitude, and cannot adapt to the material state and fermentation requirements at different stages of the entire fermentation cycle. Furthermore, traditional equipment relies solely on a single height difference for turning, and cannot match the turning depth and amplitude according to the oxygen requirements, material fluffiness, and pile temperature at different stages of fermentation, such as heating, high temperature, and cooling maturation. This easily leads to problems such as excessive turning in the early stages of fermentation, resulting in heat loss from the pile and slow activation of microorganisms; and insufficient turning amplitude in the middle and later stages of fermentation, resulting in poor material aeration and heat dissipation, and inability to break up clumps. This causes uneven fermentation and inconsistent maturation cycles, seriously affecting the quality of the finished organic fertilizer. Based on this technical problem, the following technical improvements are made: Please see Figures 2-4The inner side of the turning roller 8 is provided with an angle adjuster for adjusting the angle of the auxiliary seat 10. The angle adjuster includes: a rotating shaft 14, which is rotatably connected to the inner side of the turning roller 8 and extends to the outer side of the turning roller 8; a spur gear 16, which is fixedly connected to the outer wall of the rotating shaft 14; a sliding disk 19, which is slidably connected to the inside of the turning roller 8, and a rack 17 that meshes with the spur gear 16 is fixedly connected to the inner side of the sliding disk 19. Every two racks 17 at the same horizontal position of the turning roller 8 are fixed together by a connecting rod, and the rack 17 at the end of the roller is fixedly connected to the sliding disk 19; and a hydraulic cylinder 18, which is installed inside the turning roller 8, and the output end of the hydraulic cylinder 18 is fixedly connected to the sliding disk 19. According to the different fermentation stages, the hydraulic cylinder 18 is controlled by the PLC controller to extend and retract, thereby driving the spur gear 16 to rotate through the rack 17, and then driving the C-shaped turning rod 11 to adjust the angle through the rotating shaft 14. Combined with the stepped structure of multiple turning frames 4, the layered gradient angle turning is implemented to match the working conditions of each fermentation stage. During the material fermentation and heating stage, the PLC controller independently adjusts the tilt angle adjusters corresponding to each set of turning frames 4 to achieve differentiated angle control: the tilt angle of the C-shaped turning rod 11 on the inner side of the first set of turning frames 4 is controlled at 10°-15°, mainly for small-amplitude shallow turning, to retain the initial heat of the pile to the maximum extent and provide a stable temperature environment for microbial activation and reproduction; the tilt angle of the C-shaped turning rod 11 on the inner side of the second set of turning frames 4 is controlled at 25°-30°, to moderately loosen the middle layer of material and ensure the basic aeration and oxygen supply requirements; the tilt angle of the C-shaped turning rod 11 on the inner side of the third set of turning frames 4 is controlled at 40°-45°, to deeply disturb the deep compacted material, break the bottom layer of material accumulation and avoid deep anaerobic fermentation; As the fermentation process continues, the material successively enters the early high-temperature stage, the late high-temperature stage, and the cooling and maturation stage. According to the fermentation characteristics of each stage, the device gradually increases the inclination angle of the C-shaped turning rods 11 on the inner side of each set of stepped turning frames 4. The turning angle can be gradually increased from the initial gradient angle to a maximum of 90°. In the high-temperature stage, by increasing the turning angle and widening the turning range, the fermentation clumps of material can be fully broken up, the air permeability and heat dissipation of the material layer can be enhanced, and the overheating of the pile can be effectively prevented from burning the inoculum. In the cooling and maturation stage, the large-angle all-round turning operation is used to achieve full mixing and uniform heat dissipation of materials in the deep and shallow layers, ensuring that the material is stably and fully decomposed.

[0021] During the turning and turning of agricultural waste for organic fertilizer production, the fermented material often contains hard lumps, hard impurities, and large clumps of material. Existing traditional turning devices typically use a rigid, fixed connection between the C-shaped turning rod 11, the auxiliary seat 10, and the rotating shaft 14, lacking any buffering or obstacle avoidance function. During high-speed rotating turning operations, the turning structure impacts the hard material directly, easily causing the C-shaped turning rod 11 to deform, bend, or break. Simultaneously, equipment jamming and jamming are common, significantly reducing the continuity and stability of the turning operation, accelerating wear on equipment parts, increasing the probability of equipment failure and maintenance costs, and severely impacting the efficiency of continuous organic fertilizer production. Based on this technical problem, the following technical improvements are proposed: Please see Figures 4-5 Each auxiliary seat 10 is provided with an auxiliary bending member between it and the rotating shaft 14. The auxiliary bending member includes: a fixed seat 21, which is fixedly connected to the top of the fixed seat 21; a rotating seat 20 is fixedly connected to the bottom of the auxiliary seat 10; a connecting shaft 23 is rotatably connected to one side of the fixed seat 21; and the rotating seat 20 is rotatably connected to the outer wall of the connecting shaft 23. A connecting spring 27 is installed between the rotating seat 20 and the connecting shaft 23. A protective sleeve 22 is fixedly connected to the end of the connecting shaft 23 to isolate the connecting spring 27 from the outside. The turning roller 8 drives the auxiliary seat 10 and the C-shaped turning rod 11 to rotate at a uniform speed in a circular motion, performing routine turning and loosening operations on the fermentation material. When the C-shaped turning rod 11 comes into contact with hardened material or large hard impurities and experiences significant operating resistance during the circular turning process, the hard resistance is transmitted to the rotating seat 20 through the C-shaped turning rod 11 and the auxiliary seat 10, driving the rotating seat 20 to rotate relative to the connecting shaft 23. Simultaneously, the rotating seat 20 twists and compresses the connecting spring 27. Through the elastic torsional deformation of the connecting spring 27, the C-shaped turning rod 11 instantly generates an adaptive offset avoidance angle, effectively offsetting the hard impact force and achieving flexible avoidance operation.

[0022] In the process of organic fertilizer fermentation and turning, traditional turning equipment passively introduces air only through mechanical turning, resulting in a single and highly random oxygen supply method. It can only provide trace amounts of oxygen to the surface of the material, leaving serious oxygen-depleted blind spots in the deeper layers of the fermentation tank and within the material accumulation area. This easily leads to localized anoxic fermentation, causing problems such as souring, uneven maturation, and prolonged fermentation cycles, significantly reducing the quality of the finished organic fertilizer and failing to meet the production requirements for efficient fermentation of agricultural waste. The following technical improvements are made to address these shortcomings: Please see Figures 4-5The conical rod 13 and the C-shaped throwing rod 11 are equipped with an oxygen supply auxiliary component extending into the throwing roller 8. The oxygen supply auxiliary component includes: a fixed pipe 12 fixedly connected inside the throwing roller 8, with a connecting pipe 9 rotatably connected to the air inlet of the fixed pipe 12, and one end of the connecting pipe 9 passing through the outside of the synchronous wheel 5 and rotatably connected to the synchronous wheel 5; a first hose 15 installed at the exhaust port of the fixed pipe 12, and the other end of the first hose 15 connected to the air inlet of the rotating shaft 14, the rotating shaft 14 and the auxiliary seat 10 being connected by a second hose 24, and one end of the second hose 24 passing through the auxiliary seat 10 and the inside of the C-shaped throwing rod 11; and a nozzle 29 installed inside the conical rod 13, with the air inlet of the nozzle 29 connected to the second hose 24 through a pipe, and oxygen being sprayed out of the conical rod 13 through the nozzle 29. Connecting the connecting pipe 9 to an external oxygen supply device, external oxygen can be initially guided and transported through the connecting pipe 9 and the fixed pipe 12 inside the turning roller 8, then introduced into the rotating shaft 14 through the first flexible hose 15, and continuously transported through the second flexible hose 24 to the C-shaped turning rod 11 and the conical rod 13, and finally sprayed directionally into the material pile through the nozzle 29 inside the conical rod 13. While the device pierces, turns, and loosens the clumped material through the C-shaped turning rod 11 and the conical rod 13, it uses the nozzle 29 to achieve an integrated operation mode of turning and deep oxygen supplementation at the same time. It can directly and accurately deliver oxygen to the deep layer of the material and the fermentation blind zone, which can effectively eliminate the deep anaerobic fermentation zone of the material, greatly increase the overall oxygen content of the pile material, provide a sufficient oxygen environment for the reproduction of fermentation microorganisms, effectively improve the problem of uneven fermentation and poor maturity of the material, significantly accelerate the maturity of agricultural waste, and improve the efficiency and quality of organic fertilizer preparation.

[0023] Please see Figures 3-9A regulator for adjusting the size of the exhaust port is provided at the exhaust port of the conical rod 13. The regulator includes: a fixed sleeve 30 fixedly connected to the exhaust port of the conical rod 13, with a filter screen 39 installed at the outlet of the fixed sleeve 30; multiple sealing plates 31 arranged in a ring to block the end of the filter screen 39; the regulator also includes a drive ring 33 rotatably connected to the end of the fixed sleeve 30, with multiple inclined grooves 42 on the inner side of the drive ring 33; a connecting post 41 fixedly connected to one side of each sealing plate 31, and the connecting post 41 is located inside the inclined groove 42; multiple straight grooves 40 are opened on one side of the fixed sleeve 30, with each straight groove 40 intersecting in pairs; a limit block is fixedly connected to one side of the sealing plate 31, and the limit block is slidably connected to the inner side of the straight groove 40; a piston chamber 34 is opened on the inner side of the fixed sleeve 30, and a partition plate 35 is fixedly connected to the inner side of the piston chamber 34; the drive ring 33 is rotatably connected to the end of the fixed sleeve 30. An arc-shaped traction rod 37 is fixedly connected to one side of the ring 33. One end of the arc-shaped traction rod 37 passes through the inside of the piston chamber 34 and is fixedly connected to an arc-shaped piston 38. The arc-shaped piston 38 is slidably connected to the inside of the piston chamber 34. An arc-shaped spring 36 is installed between the partition plate 35 and the arc-shaped traction rod 37. An auxiliary pipe 32 is installed at the oil inlet of the piston chamber 34. A limiting groove matching the arc-shaped traction rod 37 is opened on the inner side of the fixed sleeve 30. A rotating ring 25 is rotatably connected to the inner side of the fixed seat 21. A piston sleeve 26 is fixedly connected to the end of the fixed seat 21. The oil outlet of the piston sleeve 26 is connected to each auxiliary pipe 32 inside the C-shaped throwing rod 11 through a connecting hose, so that the hydraulic oil inside the piston sleeve 26 enters the auxiliary pipe 32 respectively. A piston ring 28 is fixedly connected to one side of the rotating ring 25 and is rotatably connected to the inside of the piston sleeve 26. The rotating ring 25 is fixedly connected to the rotating seat 20. During the operation of the device, when the overturning encounters resistance and triggers the elastic avoidance action, the rotating seat 20 rotates simultaneously, driving the rotating ring 25 to rotate in conjunction. This, in turn, pushes the piston ring 28 to slide and compress axially inside the piston sleeve 26, causing the hydraulic oil inside the piston sleeve 26 to be pressurized and delivered to each auxiliary pipe 32 through the connecting hose. The hydraulic oil pressure further pushes the arc-shaped piston 38 in the piston chamber 34 to move, and pulls the drive ring 33 to rotate relative to the fixed sleeve 30 through the arc-shaped traction rod 37. By utilizing the guiding cooperation between the inclined groove 42 on the inner side of the drive ring 33 and the connecting column 41, combined with the limiting and guiding effect of the straight groove 40 on the sealing plate 31, multiple sealing plates 31 can be driven to slide laterally simultaneously, precisely adjusting the size of the exhaust opening formed by the encirclement of multiple sealing plates 31. Under the basic operating condition of constant total air flow from nozzle 29, adaptive matching of resistance and oxygen supply parameters can be achieved: when the turning resistance of C-shaped turning rod 11 is too high and the material is densely agglomerated, the opening of sealing plate 31 is automatically enlarged, greatly increasing the oxygen spray flow to meet the high oxygen demand of dense materials and completely eliminating the dead zone of deep anaerobic fermentation; when the turning resistance is low and the material is loose overall, the opening of sealing plate 31 is automatically reduced, the oxygen injection pressure increases accordingly and the spray flow decreases, effectively improving the oxygen penetration depth, avoiding the waste of oxygen supply to loose materials, greatly improving the oxygen utilization rate, and accurately adapting to the fermentation oxygen supply needs under different material conditions.

[0024] When the resistance of the tumbling operation decreases and the material becomes loose, the rotating seat 20 resets and rotates, simultaneously driving the rotating ring 25 and piston ring 28 to reset. The oil pressure inside the piston sleeve 26 drops, the arc spring 36 elastically resets and pushes the arc piston 38 back, driving the drive ring 33 to rotate in the opposite direction. This drives multiple sealing plates 31 to synchronously retract inward, reducing the exhaust opening diameter. After the diameter is reduced, the oxygen injection pressure increases significantly, enabling high-pressure long-distance injection, increasing the penetration depth of oxygen in the loose material, avoiding oxygen dispersion and waste, and effectively improving oxygen supply utilization. At the same time, the filter screen 39 at the end of the fixed sleeve 30 can block material dust from entering the structure throughout the process, preventing the sealing plates 31, inclined grooves 42, and straight grooves 40 from getting stuck and blocked, ensuring the long-term stable operation of the control structure.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
