Abstract

The present application relates to the technical field of fermentation, and discloses a rapid compost fermentation machine and a method thereof, which comprises a fermentation and turning machine. The present application realizes self-adaptive adjustment of the distance and the spraying angle of the nozzle through cooperation of the variable spraying assembly and the positioning plate. The flat groove and the reversing groove on the positioning plate correspond to the top plane of the fertilizer pile and the two inclined side walls respectively. When the protrusion at the top of the top rod slides along the groove body, it can drive the adjusting pipe to rise and fall synchronously, so that the distance between the nozzle and the surface of the fertilizer pile is always kept stable. At the same time, the limiting plate pushes the swing arm to drive the nozzle to adjust the angle, so that the nozzle and the spraying surface are always in an approximately vertical state. This ensures that each area of the fertilizer pile can be uniformly sprayed with water or bacteria liquid, guarantees the consistency of the fermentation environment, avoids the occurrence of local fermentation deficiency or anaerobic fermentation, improves the pass rate of the compost product, speeds up the compost fermentation speed, shortens the compost period, and meets the needs of large-scale and efficient composting.

Description

Technical Field

[0001] This invention belongs to the field of fermentation technology, specifically, it relates to a rapid composting fermentation machine and method. Background Technology

[0002] In the field of organic waste composting and fermentation treatment, in order to accelerate the fermentation process and ensure fermentation uniformity, it is necessary to spray water or bacterial solution onto the compost pile to maintain suitable fermentation humidity and microbial activity. This is one of the key steps in the composting fermentation process, which directly affects the composting efficiency and the quality of the final product.

[0003] Currently, most existing composting fermentation equipment uses vertical spraying structures with fixed nozzle positions and spray angles. However, in actual composting operations, after turning, the fertilizer pile typically presents a trapezoidal or triangular structure with a high center and low sides. The top is flat, and the sides are sloping sidewalls, with significant differences in spatial position between the top and sides. Because the nozzles of existing spraying devices remain vertical, the distance between the nozzles and the top and sides of the fertilizer pile is inconsistent. Furthermore, the spray angle on the top surface of the fertilizer pile cannot be matched with the sloping sides. This uneven spraying leads to differences in moisture content and bacterial concentration in different areas of the fertilizer pile. Some areas may have excessive moisture or bacterial solution, easily triggering anaerobic fermentation and producing foul odors, while other areas may have insufficient moisture or bacterial solution, resulting in slow fermentation. Ultimately, this prolongs the composting cycle, reduces the yield of qualified compost products, and fails to meet the demands of large-scale, high-efficiency composting fermentation.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A rapid composting fermentation machine includes a fermentation turning machine.

[0007] The fermentation turning machine is equipped with a scraper assembly and a variable spraying assembly, and a drive assembly for driving the scraper assembly and the variable spraying assembly to slide back and forth is installed at the bottom of the fermentation turning machine.

[0008] The scraper assembly includes a flattening plate for sliding on and flattening the fertilizer pile after turning.

[0009] The variable spraying assembly includes a positioning tube, an adjusting tube inserted inside the positioning tube, and a nozzle rotatably mounted at the bottom of the adjusting tube, with the nozzle aligned with the compost surface. A positioning plate is installed at the bottom of the fermentation turning machine, with a leveling groove at the center of the positioning plate and reversing grooves on both sides of the leveling groove. The adjusting tube is slidably connected to the leveling groove, and the reversing groove is an inclined groove. The leveling groove corresponds to the plane of the top of the compost pile, and the reversing groove corresponds to the inclined side wall of the compost pile, to ensure that the distance between the nozzle and the compost surface does not change significantly.

[0010] The nozzle rotation center is equipped with a swing arm, and the positioning plate on the back of the positioning plate slides vertically and slides synchronously with the adjustment pipe. The positioning plate corresponds to the reversing groove. When the nozzle aligns with the side wall of the fertilizer pile, the angle of the swing arm and the nozzle changes through the positioning plate, so that the nozzle and the spraying surface are in an approximately perpendicular state.

[0012] In a preferred embodiment of the present invention, a sleeve is installed on the slide block, and a rod is vertically inserted into the outer wall of the sleeve, with the rod and the sleeve being vertical. A locking bolt is installed between the rod and the sleeve, and a flat plate is installed at the bottom of the rod. A synchronization frame is also installed on the side wall of the sleeve, and the end of the synchronization frame is connected to the side wall of the positioning tube.

[0013] In a preferred embodiment of the present invention, the fermentation turning machine is equipped with a water conveying system, and a hose is installed at the pump output end of the water conveying system. The hose is movably connected to the fermentation turning machine, and the end of the hose is connected to the end of the positioning pipe.

[0014] In a preferred embodiment of the present invention, a goose-shaped tube is installed at the output end of the regulating tube, and the output end of the goose-shaped tube is connected to the nozzle. A pair of positioning seats are installed on the regulating tube, and a positioning shaft is rotatably installed on the pair of positioning seats. The positioning shaft is connected to the nozzle housing. A torsion spring is sleeved on the positioning shaft. One end of the torsion spring is engaged with the swing arm, and the other end of the torsion spring is engaged with the positioning seat.

[0015] In a preferred embodiment of the present invention, a sealing piston is installed on the adjusting tube. The sealing piston is movably connected to the inner wall of the positioning tube, and the sealing piston is used to ensure the sealing between the adjusting tube and the positioning tube. A positioning spring is sleeved on the outer wall of the adjusting tube. One end of the positioning spring is engaged with the end of the sealing piston, and the other end of the positioning spring is engaged with the end of the adjusting tube.

[0016] In a preferred embodiment of the present invention, a connecting seat is installed on the outer wall of the adjusting tube, a top rod is installed on the connecting seat, a limiting seat is movably installed through the outer wall of the top rod, the outer wall of the limiting seat is installed on the side wall of the positioning tube, a protrusion is installed on the top of the top rod, and the end of the protrusion is slidably disposed on the flat groove, and the flat groove is a straight groove.

[0017] In a preferred embodiment of the present invention, a limiting rod is movably installed inside the connecting seat, and fixed seats are installed at both ends of the limiting rod. A bracket is installed at the end of the fixed seat, and the bracket is slidably connected to the positioning plate. The bracket is connected to the side wall of the limiting plate.

[0018] In a preferred embodiment of the present invention, a pair of slide rails are installed on the outer side wall of the positioning plate. The pair of slide rails are parallel to each other, are vertical, and are slidably connected to the side wall of the bracket.

[0019] The following are the steps for using a rapid composting fermentation machine:

[0020] Step 1: Equipment debugging. Put the fertilizer to be processed into the fermentation chamber of the fermentation turning machine. Adjust the height of the flat plate by cooperating with the insert rod and insert sleeve. Tighten the locking bolts to fix the position of the flat plate and ensure that the flat plate can fit the top of the fertilizer pile after turning.

[0021] Step 2: Turning pretreatment. Start the fermentation turning machine to operate its internal turning structure, and fully turn and stir the fertilizer to be treated in the fermentation chamber to break up the clumps of fertilizer, so that the fertilizer materials are evenly mixed, break up the dense layer formed by the fertilizer accumulation, and ensure the air permeability and uniformity of all parts of the fertilizer. The turning operation continues until there are no obvious clumps of fertilizer and the mixture is evenly mixed, then turn off the fermentation turning machine.

[0022] Step 3: Start the drive assembly and leveling operation. Start the drive motor of the drive assembly. The output end of the drive motor drives the lead screw shaft to rotate in the slide groove. The lead screw shaft meshes with the slide block, causing the slide block to slide back and forth along the slide groove. The bellows cover extends and retracts with the slide block to seal and protect the lead screw shaft. The slide block drives the insert sleeve, insert rod and leveling plate to move synchronously. The leveling plate always abuts against the top of the fertilizer pile and slides along the top of the pile, pushing and flattening the protruding material on the top of the pile, and shaping the top of the fertilizer pile into a flat state.

[0023] Step 4: Variable spraying operation. As the slide block slides, the synchronous frame drives the positioning pipe to move synchronously, and the pump of the water delivery system is started to deliver the water or bacterial solution required for fermentation to the positioning pipe through the hose, and then into the regulating pipe. The protrusion at the top of the top rod slides along the flat groove in the center of the positioning plate to keep the distance between the nozzle and the top surface of the fertilizer pile stable, so as to achieve uniform spraying. When the protrusion slides into the reversing groove, it drives the top rod and the regulating pipe to rise and fall, so as to keep the distance between the nozzle and the side wall of the fertilizer pile stable. At the same time, the limit plate pushes the swing arm to rotate, which drives the nozzle to adjust the angle to be perpendicular to the side wall spraying surface, ensuring uniform side wall spraying.

[0024] Step 5: Cyclic operation and reset. During the reciprocating sliding of the slide, the flat plate continues to flatten the fertilizer pile, and the nozzle simultaneously completes the uniform spraying of the top and side walls of the fertilizer pile. When the nozzle moves back to the top of the fertilizer pile with the slide, the torsion spring generates an elastic reset force, which drives the swing arm and nozzle to return to the initial angle, adapting to the top spraying requirements.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] This invention achieves adaptive adjustment of nozzle distance and spray angle through the cooperation of a variable spraying component and a positioning plate. The leveling groove and reversing groove on the positioning plate correspond to the top plane of the fertilizer pile and the inclined side walls on both sides, respectively. When the protrusion at the top of the top rod slides along the groove, it can drive the adjusting pipe to rise and fall synchronously, ensuring that the distance between the nozzle and the surface of the fertilizer pile remains stable. At the same time, the limiting plate pushes the swing arm to adjust the angle of the nozzle, so that the nozzle and the spraying surface are always in a near-perpendicular state. This ensures that water or bacterial liquid can be sprayed evenly in all areas of the fertilizer pile, ensuring the consistency of the fermentation environment, avoiding insufficient local fermentation or anaerobic fermentation, improving the qualification rate of compost products, accelerating the composting fermentation speed, shortening the composting cycle, and meeting the needs of large-scale and efficient composting.

[0027] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0040] Example 1:

[0041] like Figures 1 to 9 As shown, a rapid composting fermentation machine includes a fermentation turning machine 1.

[0042] The fermentation turning machine 1 is equipped with a scraper assembly and a variable spraying assembly. The bottom of the fermentation turning machine 1 is equipped with a drive assembly for driving the scraper assembly and the variable spraying assembly to slide back and forth. The model of the fermentation turning machine 1 is XGFD-3500A[4].

[0043] The scraper assembly includes a flattening plate 2, which is used to slide on the top of the fertilizer pile after turning and to flatten the fertilizer pile.

[0044] The variable spraying assembly includes a positioning tube 12, an adjusting tube 14 is inserted into the positioning tube 12, and a nozzle 16 is rotatably installed at the bottom of the adjusting tube 14, with the nozzle 16 aligned with the compost surface. A positioning plate 26 is installed at the bottom of the fermentation turning machine 1, a leveling groove 27 is opened at the center of the positioning plate 26, and reversing grooves 28 are installed on both sides of the leveling groove 27. The adjusting tube 14 is slidably connected to the leveling groove 27, and the reversing groove 28 is an inclined groove. The leveling groove 27 corresponds to the plane of the top of the compost pile, and the reversing groove 28 corresponds to the inclined side wall of the compost pile, which is used to ensure that the distance between the nozzle 16 and the compost surface does not change significantly.

[0045] The nozzle 16 is equipped with a swing arm 30 at its rotation center. The positioning plate 26 has a vertical sliding limit plate 29 that slides synchronously with the adjusting pipe 14. The limit plate 29 corresponds to the reversing groove 28. When the nozzle 16 is aligned with the side wall of the fertilizer pile, the limit plate 29 pushes the swing arm 30 and the nozzle 16 to change their angle, so that the nozzle 16 is in a state of near perpendicularity with the spraying surface.

[0046] like Figures 1 to 9 As shown, in a specific embodiment, the drive assembly includes a lead screw shaft 7. A groove 6 is provided at the bottom of the fermentation turning machine 1, and the lead screw shaft 7 is rotatably mounted inside the groove 6. A drive motor 8 is mounted on the outer wall of the fermentation turning machine 1, and the output end of the drive motor 8 is connected to the end of the lead screw shaft 7. A slide block 5 is meshed on the lead screw shaft 7. A bellows cover 9 is installed between the side wall of the slide block 5 and the side wall of the fermentation turning machine 1, and the bellows cover 9 covers the outer wall of the groove 6 to cover the lead screw shaft 7. This structure allows for the reciprocating sliding of the scraper assembly and the variable spray assembly. Simultaneously, the bellows cover 9 provides a sealing protection for the lead screw shaft 7, preventing fertilizer debris from entering the groove 6 and affecting the normal operation of the drive assembly, thus extending the service life of the drive assembly.

[0047] like Figures 1 to 9 As shown, further, a sleeve 4 is installed on the slide block 5, and a rod 3 is vertically inserted into the outer wall of the sleeve 4, with the rod 3 and the sleeve 4 in a vertical position. A locking bolt is installed between the rod 3 and the sleeve 4. A flat plate 2 is installed at the bottom of the rod 3, and a synchronization frame 13 is also installed on the side wall of the sleeve 4. The end of the synchronization frame 13 is connected to the side wall of the positioning tube 12. The height of the flat plate 2 can be adjusted by the cooperation of the sleeve 4 and the rod 3 to adapt to fertilizer piles of different heights. The locking bolt ensures that the height of the flat plate 2 is fixed. The synchronization frame 13 enables the synchronous movement of the positioning tube 12 and the slide block 5, ensuring that the scraper assembly and the variable spraying assembly work together and improving work efficiency.

[0048] Example 2:

[0049] The difference between the above embodiments and this embodiment is that: Figures 1 to 9As shown, a water delivery system 10 is installed on the fermentation turning machine 1. A hose 11 is installed at the pump output end of the water delivery system 10, and the hose 11 is movably connected to the fermentation turning machine 1. The end of the hose 11 is connected to the end of the positioning pipe 12. Through the cooperation of the water delivery system 10, the hose 11 and the positioning pipe 12, a stable delivery of water or bacterial solution can be achieved, providing material support for the spraying operation of the nozzle 16. The movable connection design of the hose 11 can adapt to the reciprocating movement of the positioning pipe 12, avoiding damage to the pipeline by pulling.

[0050] like Figures 1 to 9 As shown, in a specific embodiment, a gooseneck tube 15 is installed at the output end of the regulating pipe 14. The output end of the gooseneck tube 15 is connected to the nozzle 16. A pair of positioning seats 17 are installed on the regulating pipe 14, and a positioning shaft 18 is rotatably installed on the pair of positioning seats 17. The positioning shaft 18 is connected to the outer shell of the nozzle 16. A torsion spring 19 is sleeved on the positioning shaft 18. One end of the torsion spring 19 is engaged with the swing arm 30, and the other end of the torsion spring 19 is engaged with the positioning seat 17. The gooseneck tube 15 can flexibly adjust the spraying direction of the nozzle 16. The cooperation between the positioning seat 17 and the positioning shaft 18 provides support for the rotation of the nozzle 16. The torsion spring 19 can realize the automatic reset of the nozzle 16 angle, ensuring that the nozzle 16 can quickly adapt to the top spraying angle when moving back to the top of the fertilizer pile, ensuring smooth cycle operation.

[0051] like Figures 1 to 9 As shown, a sealing piston 20 is further installed on the regulating pipe 14. The sealing piston 20 is movably connected to the inner wall of the positioning pipe 12, and the sealing piston 20 is used to ensure the sealing between the regulating pipe 14 and the positioning pipe 12. A positioning spring 21 is sleeved on the outer wall of the regulating pipe 14. One end of the positioning spring 21 is engaged with the end of the sealing piston 20, and the other end of the positioning spring 21 is engaged with the end of the regulating pipe 14. The sealing piston 20 ensures the sealing between the regulating pipe 14 and the positioning pipe 12, avoiding material waste and environmental pollution caused by leakage of moisture or bacterial liquid. The positioning spring 21 provides elastic support for the sealing piston 20, ensuring that the regulating pipe 14 maintains a stable fit with the positioning pipe 12 during the lifting and lowering process, thereby improving the stability and reliability of the device operation.

[0052] Example 3:

[0053] The difference between the above embodiments and this embodiment is that: Figures 1 to 9As shown, a connecting seat 22 is installed on the outer wall of the regulating pipe 14, and a top rod 23 is installed on the connecting seat 22. A limiting seat 24 is movably installed through the outer wall of the top rod 23. The outer wall of the limiting seat 24 is installed on the side wall of the positioning pipe 12. A protrusion 25 is installed on the top of the top rod 23, and the end of the protrusion 25 is slidably set on the leveling groove 27, which is a straight groove. Through the above structure, the regulating pipe 14 can be raised and lowered smoothly. The limiting seat 24 can limit and guide the top rod 23, ensuring that the protrusion 25 slides smoothly along the leveling groove 27, thereby ensuring a stable distance between the nozzle 16 and the top of the fertilizer pile and improving the uniformity of spraying.

[0054] like Figures 1 to 9 As shown, in a specific embodiment, a limiting rod 33 is movably installed inside the connecting seat 22. Fixed seats 34 are installed at both ends of the limiting rod 33, and a bracket 31 is installed at the end of each fixed seat 34. The bracket 31 is slidably connected to the positioning plate 26 and to the side wall of the limiting plate 29. A pair of slide rails 32 are installed on the outer wall of the positioning plate 26. The pair of slide rails 32 are parallel to each other and vertical, and are slidably connected to the side wall of the bracket 31. This structure enables synchronous lifting and lowering of the limiting plate 29 and the adjusting pipe 14. The slide rails 32 provide a limiting and guiding function for the bracket 31, ensuring the smooth lifting and lowering of the limiting plate 29. This, in turn, precisely pushes the swing arm 30 to adjust the angle of the nozzle 16, ensuring that the nozzle 16 is perpendicular to the spraying surface of the fertilizer pile side wall.

[0055] This invention also discloses a method for using a rapid composting fermentation machine, the steps of which are as follows:

[0056] Step 1: Equipment debugging. Put the fertilizer to be processed into the fermentation chamber of the fermentation turning machine 1. Adjust the height of the flat plate 2 by cooperating with the insert rod 3 and the insert sleeve 4. Tighten the locking bolts to fix the position of the flat plate 2, ensuring that the flat plate 2 can fit the top of the fertilizer pile after turning.

[0057] Step 2: Turning pretreatment. Start the fermentation turning machine 1 to operate its internal turning structure, fully turn and stir the fertilizer to be treated in the fermentation chamber, break up the clumps of fertilizer, make the fertilizer materials evenly mixed, break up the dense layer formed by the fertilizer accumulation, and ensure the air permeability and uniformity of all parts of the fertilizer. The turning operation continues until there are no obvious clumps of fertilizer and the mixture is even, then turn off the fermentation turning machine 1.

[0058] Step 3: Start-up of the drive assembly and leveling operation. Start the drive motor 8 of the drive assembly. The output end of the drive motor 8 drives the lead screw shaft 7 to rotate in the slide groove 6. The lead screw shaft 7 meshes with the slide block 5, causing the slide block 5 to slide back and forth along the slide groove 6. The bellows cover 9 extends and retracts with the slide block 5 to seal and protect the lead screw shaft 7. The slide block 5 drives the insert sleeve 4, insert rod 3 and leveling plate 2 to move synchronously. The leveling plate 2 always abuts against the top of the fertilizer pile and slides along the top of the pile, pushing and flattening the protruding material on the top of the pile, and leveling the top of the fertilizer pile into a flat state.

[0059] Step 4: Variable spraying operation. While the slide block 5 slides, the synchronous frame 13 drives the positioning pipe 12 to move synchronously, and the pump of the water delivery system 10 is started to deliver the water or bacterial solution required for fermentation to the positioning pipe 12 through the hose 11, and then into the regulating pipe 14. The protrusion 25 at the top of the top rod 23 slides along the flat groove 27 in the center of the positioning plate 26 to keep the distance between the nozzle 16 and the top surface of the fertilizer pile stable, so as to achieve uniform spraying. When the protrusion 25 slides into the reversing groove 28, it drives the top rod 23 and the regulating pipe 14 to rise and fall, so that the distance between the nozzle 16 and the side wall of the fertilizer pile is stable. At the same time, the limiting plate 29 pushes the swing arm 30 to rotate, which drives the nozzle 16 to adjust the angle to be perpendicular to the side wall spraying surface, so as to ensure uniform side wall spraying.

[0060] Step 5: Cyclic operation and reset. During the reciprocating sliding of the slide block 5, the flat plate 2 continues to flatten the fertilizer pile, and the nozzle 16 simultaneously completes the uniform spraying of the top and side walls of the fertilizer pile. When the nozzle 16 moves back to the top of the fertilizer pile with the slide block 5, the torsion spring 19 generates an elastic reset force, which drives the swing arm 30 and the nozzle 16 to return to the initial angle, adapting to the top spraying requirements.

[0061] The implementation principle of the rapid composting fermentation machine of the present invention is as follows:

[0062] During composting fermentation, the fermentation turner 1 is started first, and its internal turning structure is put into operation to fully turn and stir the fertilizer to be treated in the fermentation chamber, breaking up any clumps of fertilizer and ensuring that the materials inside the fertilizer are fully mixed. This ensures the permeability and uniformity of the fertilizer in all parts, completely breaking up the dense layer formed during the fertilizer accumulation process, and avoiding insufficient fermentation in some areas. This lays a solid foundation for the subsequent leveling operation 2 and the variable spraying operation of the nozzles 16, ensuring the smooth progress and effectiveness of subsequent operations.

[0063] After the turning is completed, the drive assembly is started, and the drive motor 8 starts to work. Its output end drives the lead screw shaft 7 to rotate in the slide groove 6 at the bottom of the fermentation turning machine 1. Since the lead screw shaft 7 and the slide block 5 mesh with each other, the rotation of the lead screw shaft 7 will be converted into the reciprocating sliding of the slide block 5 along the slide groove 6. The bellows cover 9 on the outside of the slide block 5 will extend and retract accordingly, which will seal and protect the lead screw shaft 7 inside the slide groove 6, preventing fertilizer debris from entering the slide groove 6 and affecting the normal operation of the drive assembly.

[0064] During the sliding process of the slide block 5, the top sleeve 4 moves synchronously. The sleeve 4 drives the flat plate 2 to move together through the insert rod 3. The locking bolt between the insert rod 3 and the sleeve 4 ensures that the height of the flat plate 2 is fixed, so that the flat plate 2 can accurately fit the top of the fertilizer pile after turning. During the sliding process, the fertilizer pile is flattened to ensure that the top of the fertilizer pile is flat, which provides a guarantee for uniform spraying in the future. At the same time, the synchronous frame 13 on the side wall of the sleeve 4 drives the positioning tube 12 to move synchronously. The positioning tube 12 is connected to the water delivery system 10 on the fermentation turning machine 1 through the hose 11. The pump of the water delivery system 10 delivers the water or bacterial solution required for fermentation to the inside of the positioning tube 12 through the hose 11, and then enters the regulating tube 14 inserted in the positioning tube 12.

[0065] A top rod 23 is installed on the connecting seat 22 on the outer wall of the regulating pipe 14. The protrusion 25 at the top of the top rod 23 is slidably set in the leveling groove 27 in the center of the positioning plate 26. The leveling groove 27 corresponds to the plane of the top of the fertilizer pile. Therefore, when the sliding seat 5 drives the positioning pipe 12 and the regulating pipe 14 to slide along the top of the fertilizer pile, the protrusion 25 slides smoothly along the leveling groove 27. At this time, the distance between the nozzle 16 at the bottom of the regulating pipe 14 and the top surface of the fertilizer pile remains stable, ensuring uniform spraying. The sealing piston 20 on the regulating pipe 14 is tightly fitted with the inner wall of the positioning pipe 12, ensuring the sealing of water or bacterial solution during the transportation process and preventing leakage. The positioning spring 21 provides elastic support for the sealing piston 20, ensuring that the regulating pipe 14 always maintains a stable fit with the positioning pipe 12 during the sliding process.

[0066] When the sliding seat 5 moves the regulating pipe 14 to the side wall of the fertilizer pile, the protrusion 25 on the top of the top rod 23 slides from the leveling groove 27 into the reversing groove 28 on both sides of the positioning plate 26. Since the reversing groove 28 is an inclined groove and corresponds to the inclined surface of the side wall of the fertilizer pile, when the protrusion 25 slides along the inclined reversing groove 28, it will drive the top rod 23 and the connecting seat 22 to rise and fall synchronously, thereby driving the regulating pipe 14 to slide vertically in the positioning pipe 12, so that the distance between the nozzle 16 and the side wall surface of the fertilizer pile remains stable, avoiding uneven spraying due to changes in spraying distance. At the same time, the limiting rod 33 on the connecting seat 22 drives the fixed seat 34 and the bracket 31 to rise and fall synchronously. The bracket 31 slides vertically along the slide rail 32 on the outer side wall of the positioning plate 26. The limiting plate 29 connected to the bracket 31 also rises and falls synchronously. The limiting plate 29 is set in correspondence with the reversing groove 28. When the nozzle moves to the corresponding position on the side wall of the fertilizer pile, the limiting plate 29 will push the swing arm 30 to rotate. The swing arm 30 drives the positioning shaft 18 to rotate on the positioning seat 17, thereby driving the nozzle 16 to adjust the angle so that the nozzle 16 is in a nearly perpendicular state to the spraying surface of the side wall of the fertilizer pile, further improving the spraying uniformity and ensuring that every part of the side wall of the fertilizer pile can be evenly sprayed with water or bacterial liquid.

[0067] In addition, one end of the torsion spring 19 on the regulating pipe 14 is attached to the swing arm 30, and the other end is attached to the positioning seat 17. When the nozzle 16 completes the side wall spraying and moves back to the top of the fertilizer pile with the sliding seat 5, the torsion spring 19 will generate an elastic restoring force, which will drive the swing arm 30 and the nozzle 16 to return to the initial angle so as to adapt to the spraying needs of the top of the fertilizer pile, ensure that the subsequent spreading and spraying operations are carried out stably, and ultimately achieve the purpose of rapid and uniform fermentation of fertilizer.

[0068] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

10. A method of using a rapid composting fermentation machine, characterized in that, The rapid composting fermentation machine according to any one of claims 1 to 9 is used in a method comprising the following steps: Step 1: Equipment debugging. Put the fertilizer to be processed into the fermentation chamber of the fermentation turning machine (1). Adjust the height of the flat plate (2) by the cooperation of the insert rod (3) and the insert sleeve (4). Tighten the locking bolt to fix the position of the flat plate (2) and ensure that the flat plate (2) can fit the top of the fertilizer pile after turning. Step 2: Turning pretreatment. Start the fermentation turning machine (1) to make its internal turning structure operate, and fully turn and stir the fertilizer to be treated in the fermentation chamber to break up the clumps of fertilizer, so that the fertilizer materials are evenly mixed, break up the dense layer formed by the fertilizer accumulation, and ensure the air permeability and uniformity of each part of the fertilizer. The turning operation continues until the fertilizer has no obvious clumps and is evenly mixed, and then the fermentation turning machine (1) is turned off. Step 3: Start-up of the drive assembly and leveling operation. Start the drive motor (8) of the drive assembly. The output end of the drive motor (8) drives the lead screw shaft (7) to rotate in the slide groove (6). The lead screw shaft (7) meshes with the slide block (5) and drives the slide block (5) to slide back and forth along the slide groove (6). The bellows cover (9) extends and retracts with the slide block (5) to seal and protect the lead screw shaft (7). The slide block (5) drives the insert sleeve (4), insert rod (3) and leveling plate (2) to move synchronously. The leveling plate (2) always abuts against the top of the fertilizer pile and slides along the top of the pile to push and flatten the protruding material on the top of the pile and level the top of the fertilizer pile. Step 4: Variable spraying operation. While the slide (5) slides, the synchronous frame (13) drives the positioning tube (12) to move synchronously. The pump of the water delivery system (10) is started to deliver the water or bacterial liquid required for fermentation to the positioning tube (12) through the hose (11) and then into the regulating tube (14). The protrusion (25) on the top of the top rod (23) slides along the flat groove (27) in the center of the positioning plate (26) to keep the distance between the nozzle (16) and the top surface of the fertilizer pile stable, so as to achieve uniform spraying. When the protrusion (25) slides into the reversing groove (28), it drives the top rod (23) and the regulating tube (14) to rise and fall, so that the distance between the nozzle (16) and the side wall of the fertilizer pile is stable. At the same time, the limiting plate (29) pushes the swing arm (30) to rotate, driving the nozzle (16) to adjust the angle to be perpendicular to the side wall spraying surface, so as to ensure uniform side wall spraying. Step 5: Cyclic operation and reset. During the reciprocating sliding of the slide (5), the flat plate (2) continues to flatten the fertilizer pile, and the nozzle (16) simultaneously completes the uniform spraying of the top and side walls of the fertilizer pile. When the nozzle (16) moves back to the top of the fertilizer pile with the slide (5), the torsion spring (19) generates an elastic reset force, which drives the swing arm (30) and the nozzle (16) to return to the initial angle and adapt to the top spraying requirements.
